<Embodiment>
As shown in FIG. 1, an audio system 1 according to an embodiment of the present invention includes a plurality of speaker devices 10-1, 10-2, and 10-3 (hereinafter referred to as speaker device 10 when not distinguished from each other) and A communication device 20 is included. FIG. 1 is an explanatory diagram showing the configuration of the audio system 1. First, the outline of the audio system 1 will be described.

  When the communication device 20 carried by the user moves as indicated by an arrow AR1 and approaches the speaker devices 10-1, 10-2, and 10-3 in order, the communication device 20 is sequentially connected by wireless communication. The audio signal being reproduced by the above is transmitted to the connected speaker devices 10-1, 10-2, 10-3 and emitted. Here, the user operates the communication device 20 to set a common overall volume value for the entire speaker device 10, and to set individual individual volume values for each of the speaker devices 10. Can do. Then, each speaker device 10 emits sound at a volume corresponding to the set overall volume value and individual volume value. As a result, the audio signal is emitted from the speaker device 10 within a specific range from the communication device 20 at a volume corresponding to the set overall volume value and individual volume value.

  FIG. 2 is an explanatory diagram showing the appearance of the speaker device 10 and the communication device 20 of the audio system 1. As shown in FIG. 2, the communication device 20 is a device in which a portable audio device 21 and a communication module 25 are connected, and wireless communication is performed between the communication module 25 of the communication device 20 and the communication unit 150 of the speaker device 10. Is done. Hereinafter, configurations of the speaker device 10 and the communication device 20 will be described in order with reference to FIGS. 3 and 4. FIG. 3 is a block diagram illustrating a configuration of the speaker device 10. FIG. 4 is a block diagram illustrating a configuration of the communication device 20.

  As shown in FIG. 3, the speaker device 10 includes an audio signal processing device 100 and a sound emitting unit 120. The audio signal processing apparatus 100 includes a control unit 101, a power supply unit 102, an amplification unit 103, an operation unit 110, a storage unit 111, a communication unit 150, and a light emitting unit 180. The communication unit 150 includes a wireless communication unit 151 and a communication control unit 152 that operate upon receiving power supply.

  The wireless communication unit 151 establishes wireless communication at the physical level by searching for the communication device 20 that exists within the communication range corresponding to the intensity of the output radio wave (hereinafter, establishment of wireless communication is establishment at the physical level). Then, communication is performed with the communication device 20 that has established wireless communication under the control of the communication control unit 152. In addition, when the communication control unit 152 is controlled to connect to the communication device 20 as described later, the encoded audio signal Sin transmitted from the communication device 20 is received during the connected state. An audio signal Sin (in this example, stereo 2 channels) obtained by decoding is output.

  Similarly, in a period in which the speaker device 10 and the communication device 20 are in a connected state, the wireless communication unit 151 performs signal processing parameters (in this example, volume values (0, 1, 2,..., 255). )) Is received and acquired from the communication device 20 and output. In addition, as described later, there is transmission request information indicating a transmission request for selection information indicating the speaker device 10 (hereinafter referred to as a specific speaker device) or the entire speaker device specified by the communication device 20 and overall setting information indicating the entire volume value. The request signal Sr included is also received from the communication device 20 and acquired and output. In addition, what is necessary is just to make specific information indicate a specific speaker apparatus by apparatus ID etc.

  That is, the state in which the speaker device 10 and the communication device 20 are connected is a state in which the audio signal Sin, the control signal Sc, and the request signal Sr transmitted from the communication device 20 can be received and acquired by the speaker device 10. It is. At this time, the channel through which the control signal Sc and the request signal Sr are communicated and the channel through which the audio signal Sin is communicated are the same channel (different frequency). Unlike the audio signal Sin, occupying another channel for the control signal Sc that is less frequently used is not preferable because the use efficiency of that channel deteriorates. Therefore, mixing in the channel reserved for the audio signal Sin and finding the gap of the audio signal Sin to be communicated and communicating the control signal Sc is more effective than providing another channel for the control signal Sc. Efficiency is good. In this example, the audio signal Sin is communicated at a predetermined interval, and the control signal Sc is communicated during a period in which the audio signal Sin is not communicated. The request signal Sr may also be handled in the same manner as the control signal Sc.

  In addition, the wireless communication unit 151 transmits a feedback signal Sf output from the control unit 101 to the communication device 20. As will be described later, the feedback signal Sf includes setting information indicating a volume value changed by operating the speaker device 10. The channel through which the feedback signal Sf is communicated may be the same channel as the channel through which the control signal Sc and the request signal Sr are communicated or may be a different channel.

  The communication control unit 152 controls communication of the wireless communication unit 151. This control is performed, for example, by outputting a signal indicating the control content from the communication control unit 152 to the wireless communication unit 151. The communication control unit 152 performs control so that signals are transmitted / received to / from the communication device 20 in which wireless communication is established at the physical level by the wireless communication unit 151. As a result, when a predetermined connection condition is satisfied, the communication device The wireless communication unit 151 is controlled to start the connection with the wireless communication unit 20. Further, when the communication control unit 152 is in a connection state with the communication device 20 and satisfies a preset disconnection condition, the communication control unit 152 disconnects the connection and ends the connection. The connection condition and disconnection condition will be described later.

  Further, the communication control unit 152 outputs connection information indicating a connection status with the communication device 20 to the control unit 101. Thereby, the control part 101 can recognize whether the speaker apparatus 10 and the communication apparatus 20 are connected by radio | wireless communication. Note that the communication control unit 152 may change the communication range by changing the intensity of the radio wave output from the wireless communication unit 151 in accordance with an operation of an operation unit (not shown).

  The power supply unit 102 is a power source that supplies power to the amplification unit 103 and the light emitting unit 180, and the start and stop of power supply are controlled by the control unit 101. The power supply destination is not limited to the amplifying unit 103 and the light emitting unit 180, but may include a processing circuit (not shown) (for example, a circuit that performs acoustic processing on the audio signal). In the control unit 101, the part that controls the power supply unit 102 is supplied with power regardless of the start and stop of power supply to the amplification unit 103 and the light emitting unit 180 of the power supply unit 102. The power to be supplied may be generated inside the apparatus by having a battery or the like inside the apparatus, or may be taken from outside the apparatus using an outlet or the like. For example, if the outlet is connected to a power strip outside the apparatus and power is supplied, power is always supplied to the communication unit 150 and the control unit 101 that controls the power supply unit 102. You may do it. In addition, the supply of power to the communication unit 150 is not limited to the supply from the power supply unit 102, and may be supplied from a power supply unit provided separately from the power supply unit 102.

  When receiving the power supply from the power supply unit 102, the amplifying unit 103 is activated and initialized, and sets the input audio signal, that is, the audio signal Sin output from the wireless communication unit 151, to the control unit 101. The signal is amplified with the amplification factor and output as an audio signal Sout. It should be noted that, immediately after receiving power supply from the power supply unit 102 under the control of the control unit 101, a larger second amplification factor (a volume value described later) is obtained from the first amplification factor over a preset time. The amplification factor of the amplifying unit 103 may be set so as to gradually change to an amplification factor according to

  As illustrated in FIG. 2, the operation unit 110 includes operation elements 110 </ b> A and 110 </ b> B. When the operation elements 110 </ b> A and 110 </ b> B are operated, the operation unit 110 outputs an operation signal indicating the operated operation element to the control unit 101. In this example, the operation element 110A is an operation element that instructs a change to decrease the volume value by “1”, and the operation element 110B is an operation element that instructs a change to increase the volume value by “1”. The operation element is not limited to such an operation element, and may be a rotary encoder, a keyboard capable of inputting numerical values, or the like.

  The storage unit 111 is a storage unit such as a non-volatile memory, and stores overall setting information and individual setting information. The overall setting information and the individual setting information are the above-described overall volume value and individual volume value, respectively, and both indicate the volume value.

  The sound emitting unit 120 includes speakers for the L channel and the R channel, and emits the signal of each channel of the audio signal Sout output from the amplifying unit 103 from the speaker for each channel.

  The light emitting unit 180 is a light emitting element such as an LED (Light Emitting Diode), and emits light in a preset mode (always on, blinking, etc.) when supplied with power from the power supply unit 102.

  The control unit 101 recognizes the connection state with the communication device 20 based on the connection information from the communication control unit 152, and when the wireless communication between the speaker device 10 and the communication device 20 is started, the power supply unit 102 Control is performed so that power supply to the amplification unit 103 is started. On the other hand, when the connection between the speaker device 10 and the communication device 20 is disconnected, the control unit 101 performs control so that the supply of power from the power supply unit 102 to the amplification unit 103 is stopped. In other words, in this example, power is supplied from the power supply unit 102 to the amplification unit 103 during a period from the start of connection to the communication device 20 until disconnection, and power supply is stopped during other periods. These controls are performed, for example, by outputting a signal indicating control contents from the control unit 101 to the power supply unit 102.

  Here, the timing at which power supply from the power supply unit 102 to the amplification unit 103 is started, which is controlled by the control unit 101, is the same as the timing at which connection between the speaker device 10 and the communication device 20 via wireless communication is started. Alternatively, the supply of electric power may be started after elapse of a preset time from the timing when the connection is started. On the other hand, the timing for stopping the supply of power may be the same as the timing at which the connection between the speaker device 10 and the communication device 20 through wireless communication is disconnected, or is set in advance from the timing at which the connection is disconnected. The supply of power may be stopped after a lapse of time.

  In addition, when the speaker device 10 and the communication device 20 are connected to each other by wireless communication, the control unit 101 performs the overall setting mode, individual setting mode, and setting stop mode determined according to the selection information included in the request signal Sr. Each part is controlled by any setting mode. Here, each setting mode will be described.

  First, the individual setting mode refers to selection information in which the specific speaker device indicates another device after the control unit 101 acquires the request signal Sr including selection information indicating that the specific speaker device indicates the own device. Alternatively, the setting mode is set in a period until the request signal Sr including selection information indicating the entire speaker device is acquired. That is, the individual setting mode is a mode indicating that the communication apparatus 20 is set as a specific speaker device for which an individual volume value is set.

  Next, the setting stop mode refers to selection information indicating that the specific speaker device indicates its own device after the control unit 101 acquires the request signal Sr including selection information indicating that the specific speaker device indicates another device. Or a setting mode set in a period until a request signal Sr including selection information indicating the entire speaker device is acquired. That is, the setting stop mode is a mode indicating that the speaker device 10 is not set for the individual volume value from the communication device 20.

  The overall setting mode is a setting mode that is set in a period other than the individual setting mode and the setting stop mode. That is, the overall setting mode is a mode that is set when the control unit 101 acquires a request signal Sr including selection information indicating the entire speaker device, and the entire speaker device is set from the communication device 20. This mode indicates that it is targeted. Therefore, in the overall setting mode, the overall volume values relating to all the speaker devices 10 connected to the communication device 20 by wireless communication are set in parallel. The above is the description of the setting mode.

  When the control unit 101 obtains the control signal Sc from the wireless communication unit 151 in the overall setting mode, the control unit 101 stores the whole stored in the storage unit 111 so that the volume value indicated by the setting information included in the control signal Sc is obtained. Update the entire volume value in the setting information. Further, when the control unit 101 acquires the control signal Sc from the wireless communication unit 151 in the individual setting mode, the control unit 101 stores the control signal Sc in the storage unit 111 so that the volume value indicated by the setting information included in the control signal Sc is obtained. The individual volume value of the individual setting information is updated. On the other hand, even when the control unit 101 acquires the control signal Sc from the wireless communication unit 151 in the setting stop mode, neither the overall setting information nor the individual setting information is updated. In the setting stop mode, the wireless communication unit 151 may not receive the control signal Sc or output it to the control unit 101.

  Further, when acquiring the operation signal from the operation unit 110, the control unit 101 updates the individual volume value of the individual setting information stored in the storage unit 111 according to the operation signal. That is, if the acquired operation signal indicates the operation element 110A, the control unit 101 decreases the individual volume value of the individual setting information stored in the storage unit 111 by “1”, and the acquired operation signal is If the child 110B is indicated, the update is performed by increasing the individual volume value of the individual setting information stored in the storage unit 111 by “1”. At this time, the increase / decrease amount may be changed according to the volume value of the setting information stored in the storage unit 111. For example, when the volume value is “0” to “122”, it may be increased or decreased by “1”, and when it is “123” to “255”, it may be increased or decreased by “5”. In the individual setting mode, the control unit 101 updates the individual setting information only according to the setting information included in the control signal Sc as described above, and sets the individual setting information according to the operation signal. It may not be updated.

  Then, the control unit 101 sets an amplification factor for the amplification unit 103 according to the overall setting information and the individual setting information stored in the storage unit 111. In this example, the amplification factor may be set according to the product of the overall volume value indicated by the overall setting information and the individual volume value indicated by the individual setting information, but the overall volume value indicated by the overall setting information and the individual setting information are As long as the amplification factor is set according to the individual volume value shown, any mode may be used.

  In addition, the control unit 101 outputs a feedback signal Sf including either the entire setting information or the individual setting information stored in the storage unit 111 as setting information to the wireless communication unit 151. Here, when the control unit 101 acquires the request signal Sr including the transmission request information, the control unit 101 reads out the entire setting information from the storage unit 111 and outputs a feedback signal Sf including the entire setting information as the setting information. When the setting mode is switched from another setting mode, that is, when the request signal Sr including the selection information indicating that the specific speaker device indicates its own device is acquired, the individual setting information is read from the storage unit 111, and this individual setting information is read. Is output as the setting information. Here, the output of the feedback signal Sf is performed in response to an inquiry about a state change from the communication device 20, as will be described later.

  Further, the control unit 101 controls to supply power from the power supply unit 102 to the light emitting unit 180 during the period of the individual setting mode, and causes the light emitting unit 180 to emit light in a preset manner, thereby automatically. Notifies that the device is in the individual setting mode. The above is the description of the configuration of the speaker device 10.

  Next, the configuration of the communication device 20 will be described. The communication device 20 includes a portable audio device 21 and a communication module 25 as shown in FIG. The portable audio device 21 includes a control unit 211, a storage unit 212, an operation unit 213, a display unit 214, an audio output unit 215, and an interface 216, which are connected via a bus 210, and are not shown. Battery). The communication module 25 includes an interface 251, a wireless communication unit 252, a communication control unit 253, and an operation unit 255.

  The portable audio device 21 and the communication module 25 are connected by interfaces 251 and 216. In this example, the communication module 25 is supplied with power from the power supply unit (not shown) of the portable audio device 21 via the interfaces 251 and 216 by connection with the portable audio device 21. Therefore, when the communication module 25 is detached from the portable audio device 21 and the connection is released, the function of each part of the communication module 25 is stopped. Note that the communication module 25 may include a battery that supplies power to each unit inside the communication module 25.

  The control unit 211 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU controls each part of the portable audio device 21 via the bus 210 by reading the control program from the ROM into the RAM and executing it. The details of control in the control unit 211 will be described later.

  The storage unit 212 is a large-capacity storage unit such as a hard disk or a nonvolatile memory, and stores data indicating an audio signal and a video signal. Also, setting information indicating the volume value is stored.

  The operation unit 213 includes an operation element for a user to perform an operation. When the user operates the operation unit 15, an operation signal indicating the operation content is output to the control unit 211. In this example, the operation element has an operation element that can be rotated, and the clockwise rotation of the operation element when the display unit 214 displays according to the setting information as described later is as follows. A change for increasing the volume value is instructed, and a counterclockwise rotation indicates a change for decreasing the volume value.

  The display unit 214 is a display device such as a liquid crystal display that displays video, and performs display in accordance with a video signal and an image signal input by the control of the control unit 211.

  The audio output unit 215 has a connection terminal for connecting sound emission means such as headphones, and supplies an audio signal input by the control of the control unit 211 to the connected sound emission means.

  The interface 216 is a connection terminal for connecting to an external device and inputting / outputting various data. In this example, the communication module 25 is connected to the interface 216, and the audio signal Sin and the control signal Sc are output to the connected communication module 25 under the control of the control unit 211. The interface 216 receives a feedback signal Sf from the connected communication module 25 and outputs the feedback signal Sf to the control unit 211.

  For example, the control unit 211 reads out and reproduces data indicating the audio signal stored in the storage unit 212 in accordance with the selection and reproduction operation by the user of the operation unit 213, for example, 16-bit 48 kHz sampling × 2 ch audio signal It is output to the audio output unit 215 and the interface 216 as Sin. In addition, when the setting information is updated, that is, when the user operates the operation unit 213, the control unit 211 outputs a control signal Sc including the setting information stored in the storage unit 212 to the interface 216. . Further, the control unit 211 may output the control signal Sc including the setting information stored in the storage unit 212 even when the communication device 20 and the speaker device 10 are connected.

  At this time, the control unit 211 acquires information indicating whether or not the speaker device 10 and the communication device 20 are in the connected state from the communication control unit 253, and outputs the audio signal Sin to the audio output unit 215 in the connected state. Or the output of the audio signal Sin and the control signal Sc to the interface 216 may be stopped when the connection state is not established. When outputting the audio signal Sin to the audio output unit 215, the control unit 211 may adjust the output level of the audio signal Sin according to the volume value indicated by the setting information stored in the storage unit 212. However, the output level of the audio signal Sin output to the interface 216 is not adjusted. This is because sound quality degradation such as keeping the SN ratio high can be reduced by not adjusting the output level of the audio signal Sin before transmission to the speaker device 10.

  In addition, the control unit 211 generates an image signal indicating an image corresponding to the volume value indicated by the setting information stored in the storage unit 212 and outputs the image signal to the display unit 214, thereby causing the display unit 214 to respond to the setting information. Display. This display is performed, for example, by displaying the volume value indicated by the setting information as shown in FIG. 2 and the volume value as a bar graph.

  Further, when acquiring the feedback signal Sf from the interface 216, the control unit 211 updates the volume value of the setting information stored in the storage unit 212 in accordance with the setting information included in the feedback signal Sf.

  In addition, the control unit 211 displays the volume value indicated by the setting information stored in the storage unit 212 in accordance with the operation signal acquired from the operation unit 213 when the display unit 214 performs display according to the setting information. Update as you increase or decrease. That is, if the acquired operation signal indicates clockwise rotation, the control unit 211 increases the volume value of the setting information stored in the storage unit 212, and the acquired operation signal rotates counterclockwise. Is updated by decreasing the volume value of the setting information stored in the storage unit 111. Here, the amount of increase or decrease of the volume value may be determined according to the amount of rotation of the operation element, and the volume value may be changed by “1” for each preset rotation angle. . Then, the control signal Sc may be output every time the volume value changes.

  When the volume value indicated by the setting information stored in the storage unit 212 is updated in this way, the display on the display unit 214 changes in accordance with the update. For example, when the volume value displayed on the display unit 214 is 135 and the volume value is updated so as to decrease by “1”, the volume value indicated by the setting information stored in the storage unit 212 is “135. To “134”, the volume value displayed on the display unit 214 also changes to “134”.

  The interface 251 is a connection terminal for connecting to an external device and inputting / outputting various data. In this example, the portable audio device 21 is connected to the interface 251, and the audio signal Sin and the control signal Sc output from the interface 216 of the portable audio device 21 are output to the wireless communication unit 252. Further, the interface 251 outputs the feedback signal Sf output from the wireless communication unit 252 to the interface 216 of the portable audio device 21.

  The wireless communication unit 252 searches for the speaker device 10 existing within the communication range corresponding to the strength of the output radio wave, establishes wireless communication at a physical level, and the communication control unit 253 with the speaker device 10 that has established wireless communication. Communication is performed under control. When the connection between the speaker device 10 and the communication device 20 is started by wireless communication with the wireless communication unit 151 of the speaker device 10 as described above, the wireless communication unit 252 is in a period until the connection is disconnected. The audio signal Sin output from the interface 251 is encoded and transmitted to the speaker device 10.

  Here, the transmission of the audio signal Sin may be performed only when the speaker device 10 and the communication device 20 are in the connected state, or the audio signal Sin is transmitted regardless of the connected state, and the connected state. If not, the audio signal Sin may not be acquired in the speaker device 10.

  Similarly, during a period in which the speaker device 10 and the communication device 20 are in a connected state, the wireless communication unit 252 determines the request signal Sr and the control signal Sc output from the interface 251 under the control of the communication control unit 253. 10 is transmitted by wireless communication. Further, the wireless communication unit 252 receives the feedback signal Sf from the speaker device 10 and outputs it to the interface 251.

  The operation unit 255 has an operation element for a user to perform an operation. When the user operates the operation unit 255, an operation signal indicating the operation content is output to the communication control unit 253. In this example, a toggle switch is used as the operator, and when it is turned on, an operation signal indicating that it is turned on is output to the communication control unit 253.

  The communication control unit 253 controls communication of the wireless communication unit 252. This control is performed by, for example, outputting a signal indicating the control content from the communication control unit 253 to the wireless communication unit 252. The communication control unit 253 performs control so as to transmit and receive signals to and from the speaker device 10 for which wireless communication has been established at the physical level by the wireless communication unit 252, and as a result, in the same manner as the communication control unit 152 of the speaker device 10, When the set connection condition is satisfied, the wireless communication unit 252 is controlled to start connection with the speaker device 10. Further, when the communication control unit 253 is in a connection state with the speaker device 10 and satisfies a preset disconnection condition, the communication control unit 253 disconnects the connection and ends the connection. In addition, the communication control unit 253 stores a connection list that identifies the speaker device 10 in a connected state. The connection list will be described later. Note that the communication control unit 253 may change the communication range by changing the intensity of the radio wave output from the wireless communication unit 252 according to an operation of an operation unit (not shown).

  Further, the communication control unit 253 generates selection information and transmission request information according to the operation signal from the operation unit 255 and causes the wireless communication unit 252 to transmit a request signal Sr including the selection information and transmission request information. In this example, selection information and transmission request information are generated as follows.

  First, when the communication device 20 and the speaker device 10 are first connected by wireless communication, the communication control unit 253 generates transmission request information and includes the transmission request information for the speaker device 10. The request signal Sr is transmitted from the wireless communication unit 252. The request signal Sr including the transmission request information is not transmitted to the speaker devices 10 connected after the second. Here, the communication control unit 253 determines whether the connection by wireless communication is the first or second or later by referring to the connection list. That is, when the speaker device 10 already exists in the connection list, it can be determined that the second or later.

  When the operation signal is acquired by operating the operation unit 255 after being connected to the plurality of speaker devices 10, the communication control unit 253 refers to the connection list, identifies one of the speaker devices 10, and sets In order to select a specific speaker device as a target, selection information indicating the specified speaker device 10 as a specific speaker device is generated, and a request signal Sr including the selection information is transmitted from the wireless communication unit 252. In this example, the speaker device 10 is specified from the top of the connection list (in the order from the early connection state). The specification of the speaker device 10 is not limited to a mode performed from the top of the connection list, and may be random. Further, display according to the connection list may be performed on the display unit such as the display unit 214 and specified by operation of the operation unit such as the operation units 213 and 255, or radio communication radio waves from each speaker device 10 may be specified. The intensity may be detected by the wireless communication unit 252 and specified according to the detected intensity. Furthermore, two or more speaker devices 10 may be specified simultaneously in a predetermined manner.

  Then, whenever the communication control unit 253 acquires an operation signal by operating the operation unit 255, the communication control unit 253 changes the specified speaker device 10 to newly generate selection information, and a request signal Sr including the selection information. Is transmitted from the wireless communication unit 252. By repeating this, when the specification of all speaker devices 10 in the connection list is completed, the communication control unit 253 generates selection information indicating the entire speaker device in order to select the entire speaker device as a setting target, and the selection is performed. A request signal Sr including information is transmitted from the wireless communication unit 252. At this time, the request signal Sr also includes transmission request information. As for the transmission request information, any speaker device 10 may be designated and transmitted as a request signal Sr acquired by the speaker device 10.

  Thereafter, when the communication control unit 253 obtains an operation signal by operating the operation unit 255, the communication control unit 253 again specifies one of the speaker devices 10 from the connection list and selects the specified speaker in order to select the specific speaker device as a setting target. Selection information indicating the device 10 as a specific speaker device is generated, a request signal Sr including the selection information is transmitted from the wireless communication unit 252, and the above process is repeated. At this time, a light emitting unit (not shown) is provided in the communication module 25, and a light emitting mode (for example, green light emission) when the communication control unit 253 selects the entire speaker device as a setting target and a specific speaker device are selected. The setting target may be notified by separating the light emission mode (for example, red light emission) at the time of performing.

  The communication control unit 253 transmits a request signal Sr including selection information of various contents from the wireless communication unit 252 by the operation of the operation unit 255 by the user. Each setting mode is set by 101. The above is the description of the configuration of the communication device 20.

  Next, operations of the speaker device 10 and the communication device 20 in the audio system 1 will be described with reference to FIGS. FIG. 5 is an explanatory diagram of the wireless communication between the speaker device 10 and the communication device 20. 6 to 10 are explanatory diagrams of operations of the speaker device 10 and the communication device 20 when the speaker device 10 and the communication device 20 are connected by wireless communication. Is.

  FIG. 11 is an explanatory diagram showing changes in the overall setting information, individual setting information, and setting information in the storage unit 212 of the communication device 20 in the operations from FIG. 6 to FIG. It is. In this figure, the horizontal axis represents time, and the vertical axis represents “0” to “255” from “0%” to “100%” for the volume values of the setting information, the entire setting information, and the individual setting information. ". In the following description, the volume value is described as being replaced from “0%” to “100%” for the correspondence with FIG.

  Here, the speaker devices 10-1, 10-2, and 10-3 are installed in advance, and the user carries the communication device 20, and the user has the speaker devices 10-1, 10-2, After entering the communication range from outside the communication range 10-3, the operation units 213 and 255 are operated to change the overall volume values and individual volume values of the speaker devices 10-1, 10-2, and 10-3. It is assumed that an instruction is given and the user leaves the communication range. In the portable audio device 21 of the communication device 20, it is assumed that an audio signal is reproduced by a user operation. The wireless communication performed between the speaker device 10 and the communication device 20 in this case will be described.

  As shown in FIG. 5, first, in a state where the speaker device 10 and the communication device 20 are outside the communication range, a communication partner that can establish wireless communication with each other is searched. At this time, power is not supplied to the amplification unit 103 of the speaker device 10. When the user moves and the communication device 20 enters the communication range of the speaker device 10, the speaker device 10 and the communication device 20 detect a communication partner, and the wireless communication unit 151 and the communication device of the speaker device 10 are detected. The 20 wireless communication units 252 establish wireless communication with each other at the physical level.

  When the wireless communication is established, the wireless communication unit 151 controls the communication control unit 152 of the speaker device 10 so that the wireless communication unit 151 requests the connection with the communication device 20 and the identification information for identifying the own device (for example, device ID, A connection request signal including a group ID, product information, manufacturer information, and the like is transmitted to the communication device 20. The speaker device 10 transmits a connection request signal and waits for a determination as to whether or not the connection condition is satisfied. In this example, the connection condition is that the speaker device 10 receives a connection response signal indicating connection permission transmitted from the communication device 20 in response to the connection request signal.

  When the communication device 20 receives the connection request signal transmitted from the speaker device 10 by the wireless communication unit 252, the communication control unit 253 evaluates the identification information and determines whether to connect to the speaker device 10. The determination based on the evaluation of the identification information may be performed as follows, for example. The identification information in the speaker device 10 is defined as a group ID (for example, groups 1, 2, and 3), and this group ID can be set by operating means (not shown) such as a DIP switch. On the other hand, in the communication module 25 of the communication device 20, similarly, the group ID of the communication module 25 can be set by operating means (not shown) such as a DIP switch.

  In such a configuration of the speaker device 10 and the communication device 20, when the connection request signal including identification information indicating the group ID transmitted from the speaker device 10 is received by the wireless communication unit 252 of the communication device 20, the communication control unit 253. May determine whether the group ID indicated by the identification information matches the group ID set in the communication module 25. In this way, since a pair of connectable speaker device 10 and communication device 20 can be easily set, when a plurality of speaker devices 10 are installed, the group ID of each speaker device 10 is set. By setting, the speaker device 10 connected to the communication device 20 by wireless communication can be easily set.

  When the communication device 20 determines to connect to the speaker device 10, the communication device 20 transmits a connection response signal indicating connection permission to the speaker device 10. Further, when it is determined that the speaker device 10 is not connected, a connection response signal may not be transmitted, or a connection response signal indicating that connection is not permitted may be transmitted.

  When the communication control unit 152 of the speaker device 10 receives a connection response signal indicating connection permission by the wireless communication unit 151, the communication control unit 152 determines that the connection condition described above is satisfied, and connects the speaker device 10 and the communication device 20 by wireless communication. Start and connect. Accordingly, the audio signal Sin, the control signal Sc, the request signal Sr, and the feedback signal Sf can be transmitted and received between the speaker device 10 and the communication device 20. In addition, the control unit 101 supplies power from the power supply unit 102 to the amplification unit 103, and sets the amplification factor according to the entire setting information and the individual setting information stored in the storage unit 111 in the amplification unit 103.

  Here, the communication control unit 152 of the speaker device 10 continues to determine the connection condition for a certain period, but when the connection response signal indicating connection permission is not received by the wireless communication unit 151 within the period, A communication device capable of establishing wireless communication by searching for whether or not another communication device 20 exists within the communication range by maintaining a state in which wireless communication is established without performing connection with the communication device 20 If 20 exists, the connection with the communication device 20 is attempted as described above. A search is started to determine whether another communication device 20 exists within the communication range.

  Thus, the speaker device 10 is connected to one communication device 20 by wireless communication, while the communication device 20 is connected to a plurality of speaker devices 10 by wireless communication. Then, the audio signal Sin reproduced in the portable audio device 21 is emitted from the plurality of connected speaker devices 10.

  Next, when the speaker device 10 starts connection with the communication device 20, the speaker device 10 continues to determine whether or not the disconnection condition is satisfied. In this example, the disconnection condition is that the communication device 20 moves out of the communication range or the communication module 25 is removed from the portable audio device 21 so that wireless communication cannot be established.

  If the user carrying the communication device 20 further moves and moves outside the communication range of the speaker device 10, wireless communication between the speaker device 10 and the communication device 20 cannot be established, and the communication control unit 152 of the speaker device 10, communication The communication control unit 253 of the device 20 determines that the disconnection condition described above is satisfied, and disconnects the connection between the speaker device 10 and the communication device 20. Then, the control unit 101 of the speaker device 10 stops the power supply from the power supply unit 102 to the amplification unit 103, and the wireless communication unit 252 does not acquire the audio signal Sin. Sound emission from the sound emission unit 120 stops.

  Next, the operations of the speaker device 10 and the communication device 20 from when the wireless communication connection with the communication device 20 is started in order of the speaker devices 10-1, 10-2, and 10-3 are illustrated in FIG. 11 will be used for explanation. The operation of the power supply unit 102 for supplying power to the amplification unit 103 is not described here.

  First, it demonstrates using FIG. When the communication device 20 moves and enters the communication range of the speaker device 10-1, the speaker device 10-1 and the communication device 20 are connected by wireless communication. As a result, the communication control unit 253 of the communication device 20 adds the device ID indicating the speaker device 10-1 to the connection list and the transmission request information is sent to the speaker device 10-1 that is first connected. The included request signal Sr is transmitted from the wireless communication unit 252. When the control unit 101 of the speaker device 10-1 receives and acquires the request signal Sr, the control unit 101 reads out the entire setting information stored in the storage unit 111 of the speaker device 10-1, and sets the read out entire setting information. A feedback signal Sr included as information is output to the wireless communication unit 151 as a response to the request signal Sr, and is transmitted to the communication device 20.

  When the communication device 20 receives the feedback signal Sr, the control unit 211 of the communication device 20 indicates the volume value indicated by the setting information stored in the storage unit 212 of the communication device 20 by the setting information included in the feedback signal Sf. Update to the volume value. As a result, under the control of the control unit 211, a display corresponding to the volume value indicated by the updated setting information is displayed on the display unit 214, and the user can change the overall settings stored in the storage unit 111 of the speaker device 10-1. It is possible to recognize the entire volume value indicated by the information, that is, the current setting of the entire volume value in the speaker device 10-1.

  When the communication device 20 further moves and enters the communication range of the speaker device 10-2, the speaker device 10-2 and the communication device 20 are connected by wireless communication. Thereby, the communication control part 253 of the communication apparatus 20 adds apparatus ID etc. which show the speaker apparatus 10-2 to a connection list. And if the communication control part 253 notifies the control part 211 that it connected with the new speaker apparatus 10-2, the control part 211 will read the setting information memorize | stored in the memory | storage part 212, and the read setting information Is output to the communication module 25 and transmitted from the wireless communication unit 252.

  Note that if the communication control unit 253 stores the setting information included in the control signal Sc or feedback signal Sf communicated last in the wireless communication unit 252, the communication module 25 does not need to be notified of the setting information. This process can be completed. That is, the communication control unit 253 may transmit the setting information stored in the communication control unit 253 from the wireless communication unit 252 as the control signal Sc. In addition, the control signal Sc may be transmitted to the speaker devices 10-1 and 10-2, or may be transmitted by specifying the speaker device 10-2. Sc may not be transmitted.

  When the control unit 101 of the speaker device 10-2 receives and acquires the control signal Sc, since it is set as the overall setting mode at this point in time as described above, the setting information indicated by the control signal Sc indicates The entire volume value indicated by the entire setting information stored in the storage unit 111 is updated so as to be the volume value.

  When the communication device 20 further moves and enters the communication range of the speaker device 10-3, the speaker device 10-3 and the communication device 20 are connected by wireless communication. Since the subsequent processing is the same as that when connecting to the speaker device 10-2, the description thereof is omitted. In this way, the entire volume values set in the speaker devices 10-1, 10-2, 10-3 are the same. Here, the connection list stored in the communication control unit 253 of the communication device 20 is a list arranged in the order of connection with the speaker devices 10-1, 10-2, and 10-3 as shown in FIG.

  Next, the description will be continued with reference to FIG. First, t0 shown in FIG. 7 corresponds to t0 on the horizontal axis (time) in FIG. Hereinafter, the same applies to tn (n = 0, 1, 2,...). At time t0, the volume value indicated by the setting information related to the communication device 20 (hereinafter referred to as volume value Vc) is “40%”, and the overall volume value indicated by the overall setting information (hereinafter referred to as overall volume value Va) is the same. “40%”. As described above, the overall volume value Va does not become a different value even if the processing described later is performed, and is common to the speaker devices 10-1, 10-2, and 10-3. Since it is a value, it is written together. The individual volume value indicated by the individual setting information related to the speaker device 10-1 (hereinafter referred to as the individual volume value Vp1) is “80%”, and the individual volume value indicated by the individual setting information related to the speaker device 10-2 (hereinafter referred to as “individual volume value Vp1”). The individual volume value Vp2) is “20%”, and the individual volume value (hereinafter referred to as individual volume value Vp3) indicated by the individual setting information related to the speaker device 10-3 is “60%”. Hereinafter, when the individual volume values Vp1, Vp2, and Vp3 are described together, they are referred to as individual volume values Vp.

  At this time, the amplification factor set in the amplification unit 103 of the speaker device 10-1 corresponds to the product “40%” × “80%” = “32%” of the entire volume value Va and the individual volume value Vp1. In this example, the amplification factor is set as “32%” when the settable range is changed from “0%” to “100%”. Similarly, the amplification factor set in the amplification unit 103 of the speaker device 10-2 is “40%” × “20%” = “8%”, and the amplification factor set in the amplification unit 103 of the speaker device 10-3. Is “40%” × “60%” = “24%”.

  At this time, when the user operates the operation unit 213 of the communication device 20 to instruct the change of the volume value Vc, the control unit 211 changes the volume value Vc indicated by the setting information stored in the storage unit 212 to Update the volume value according to the instruction. In addition, the control unit 211 outputs a control signal Sc including setting information indicating the updated volume value Vc to the communication module 25 and causes the wireless communication unit 252 to transmit the control signal Sc. At this time, the user can operate the operation unit 213 while confirming that the display of the volume value on the display unit 214 changes according to the operation of the operation unit 213. Vc can be specified accurately.

  When the speaker devices 10-1, 10-2, and 10-3 receive the control signal Sc, the control unit 101 is set as the overall setting mode at this time point. -2 and 10-3, the overall volume value Va indicated by the overall setting information stored in the storage unit 111 is updated to become the volume value Vc indicated by the setting information included in the control signal Sf. In addition, each control unit 101 of the speaker devices 10-1, 10-2, and 10-3 sets, in the amplification unit 103, the updated overall volume value Va and an amplification factor according to the individual volume value Vp. As a result, the volume of the audio signal Sin emitted from the sound emitting unit 120 of each of the speaker devices 10-1, 10-2, and 10-3 changes. Here, it is assumed that the volume value Vc is instructed to be changed from “40%” to “60%”, and the volume value Va is similarly changed by the transmission / reception of the control signal Sc (see FIG. 11: t0 → t1). At this time, the amplification factor set in the amplification unit 103 of the speaker device 10-1 changes from “32%” to “48%” (= “Va = 60%” × “Vp1 = 80%”). Similarly, the set amplification factor also changes for the speaker devices 10-2 and 10-3.

  Next, when the user operates the operation unit 255 of the communication device 20, the communication control unit 253 specifies the speaker device 10-1 at the beginning of the connection list in order to select the specific speaker device as the setting target. The wireless communication unit 252 transmits a request signal Sr including selection information indicating the speaker device 10-1 as a specific speaker device. Thereby, the control part 101 of the speaker apparatus 10-1 will switch from whole setting mode to individual setting mode, if this request signal Sr is received and acquired. On the other hand, when receiving and acquiring the request signal Sr, the control unit 101 of the speaker devices 10-2 and 10-3 switches from the overall setting mode to the setting stop mode.

  When switching to the individual setting mode, the control unit 101 of the speaker device 10-1 supplies power to the light emitting unit 180 to start light emission. Further, the control unit 101 of the speaker device 10-1 reads the individual setting information in the storage unit 111, outputs a feedback signal Sf including the read individual setting information as setting information to the wireless communication unit 151, and transmits it to the communication device 20. Send it.

  When the communication device 20 receives the feedback signal Sr, the control unit 211 of the communication device 20 uses the volume value Vc indicated by the setting information stored in the storage unit 212 of the communication device 20 as the setting information included in the feedback signal Sf. The volume is updated to the individual volume value Vp1 (“80%”), and the individual volume value Vp1 is copied to the volume value Vc. Thereby, the display according to the volume value Vc indicated by the updated setting information is displayed on the display unit 214 under the control of the control unit 211, and the user is stored in the storage unit 111 of the speaker device 10-1. The individual volume value Vp1 indicated by the setting information, that is, the current setting of the individual volume value Vp1 in the speaker device 10-1 can be recognized (see t2 in FIG. 11).

  At this time, when the user operates the operation unit 213 of the communication device 20 to instruct the change of the volume value Vc, the control unit 211 changes the volume value Vc indicated by the setting information stored in the storage unit 212 to Update the volume value according to the instruction. Here, it is assumed that an instruction to change the volume value Vc from “80%” to “40%” is given (see FIG. 11: t2 → t3).

  The control unit 211 outputs a control signal Sc including setting information indicating the updated volume value Vc to the communication module 25. At this time, the communication control unit 253 prevents transmission from the wireless communication unit 252. Controlled by.

  Proceeding to FIG. Next, when the user operates the operation unit 255 of the communication device 20, first, the communication control unit 253 of the communication device 20 transmits a control signal Sc including setting information stored in the storage unit 212 to the wireless communication unit 252. To send from. In this transmission, when the communication control unit 253 notifies the control unit 211 that the operation unit 255 has been operated, the control unit 211 reads the setting information stored in the storage unit 212, and reads the read setting information. The control signal Sc including the control signal Sc may be output to the communication module 25, or the control signal Sc output to the communication module 25 in response to the user's operation of the operation unit 213 as described above. The communication control unit 253 stores the latest setting information stored from the wireless communication unit 252 when the communication control unit 253 obtains the operation signal by the operation of the operation unit 255. The control signal Sc may be transmitted.

  Thus, when the control unit 101 of the speaker device 10-1 receives the control signal Sc, since it is in the individual setting mode at this time, the volume value Vc (“40%” indicated by the setting information included in the control signal Sc is set. ”), The individual volume value Vp1 indicated by the individual setting information stored in the storage unit 111 of the speaker device 10-1 is updated (see t4 in FIG. 11), and the volume value Vc is changed to the individual volume value Vp1. Copied. Thereby, the control unit 101 of the speaker device 10-1 amplifies the amplification factor according to the product (“24%”) of the entire volume value Va (“60%”) and the individual volume value Vp1 (“40%”). Section 103. Therefore, the volume level of the audio signal Sin to be emitted is in accordance with the overall volume value Va and the individual volume value Vp1. Here, since the other speaker devices 10-2 and 10-3 are set to the setting stop mode, the overall setting information and the individual setting information are not updated even when the control signal Sc is received. Therefore, in FIG. 8, the description of the communication of the control signal Sc to the speaker devices 10-2 and 10-3 is omitted (hereinafter the same is omitted).

  In addition, the communication control unit 253 specifies the speaker device 10-2 next to the speaker device 10-1 in the connection list, and receives the request signal Sr including selection information indicating the speaker device 10-2 as the specific speaker device. Transmission is performed from the wireless communication unit 252. Thereby, the control part 101 of the speaker apparatus 10-2 will switch from setting stop mode to individual setting mode, if this request signal Sr is received and acquired. On the other hand, when receiving and acquiring the request signal Sr, the control unit 101 of the speaker device 10-1 switches from the individual setting mode to the setting stop mode, stops the power supply to the light emitting unit 180, and the light emitting unit 180 emits light. No longer. The speaker device 10-3 remains in the setting stop mode.

  Since the subsequent processing in the speaker device 10-2 is the same as that of the above-described speaker device 10-1, it will be briefly described. First, the light emitting unit 180 of the speaker device 10-2 emits light, the individual setting information stored in the storage unit 111 of the speaker device 10-2 is read, and a feedback signal Sf indicated as setting information is transmitted to the communication device 20. Is done. Then, the volume value indicated by the setting information stored in the storage unit 212 of the communication device 20 is updated to become the individual volume value Vp2 (“20%”) (see t5 in FIG. 11), and the individual volume value Vp2 is updated. Copied to volume value Vc.

  When the operation unit 213 of the communication unit 20 is operated to change the volume value Vc from “20%” to “80%”, the setting information stored in the storage unit 212 is updated (FIG. 11: t5). (See t6).

  Proceeding to FIG. Next, when the user operates the operation unit 255 of the communication device 20, first, the communication control unit 253 of the communication device 20 transmits a control signal Sc including setting information stored in the storage unit 212 to the wireless communication unit 252. To send from. Accordingly, when the control unit 101 of the speaker device 10-2 receives the control signal Sc, since it is in the individual setting mode at this time, the volume value Vc (“80%” indicated by the setting information included in the control signal Sc is set. ”), The individual volume value Vp2 indicated by the individual setting information stored in the storage unit 111 of the speaker device 10-2 is updated (see t7 in FIG. 11), and the volume value Vc is changed to the individual volume value Vp2. Copied. Thereby, the control unit 101 of the speaker device 10-2 amplifies the amplification factor according to the product (“48%”) of the total volume value Va (“60%”) and the individual volume value Vp2 (“80%”). Section 103. Accordingly, the volume level of the audio signal Sin to be emitted is in accordance with the overall volume value Va and the individual volume value Vp2. Here, since the other speaker devices 10-1 and 10-3 are set to the setting stop mode, the overall setting information and the individual setting information are not updated even when the control signal Sc is received.

  Further, the communication control unit 253 specifies the speaker device 10-3 next to the speaker device 10-2 in the connection list, and receives a request signal Sr including selection information indicating the speaker device 10-3 as the specific speaker device. Transmission is performed from the wireless communication unit 252. Thereby, the control part 101 of the speaker apparatus 10-3 will switch from setting stop mode to individual setting mode, if this request signal Sr is received and acquired. On the other hand, when receiving and acquiring this request signal Sr, the control unit 101 of the speaker device 10-2 switches from the individual setting mode to the setting stop mode, stops the power supply to the light emitting unit 180, and the light emitting unit 180 emits light. No longer. The speaker device 10-1 remains in the setting stop mode.

  Since the subsequent processing in the speaker device 10-3 is the same as that of the above-described speaker device 10-2, a brief description will be given. First, the light emitting unit 180 of the speaker device 10-3 emits light, the individual setting information stored in the storage unit 111 of the speaker device 10-3 is read, and a feedback signal Sf indicated as setting information is transmitted to the communication device 20. Is done. Then, the volume value indicated by the setting information stored in the storage unit 212 of the communication device 20 is updated to become the individual volume value Vp3 (“40%”) (see t8 in FIG. 11), and the individual volume value Vp3 is updated. Copied to volume value Vc.

  When the operation unit 213 of the communication unit 20 is operated to change the volume value Vc from “40%” to “20%”, the setting information stored in the storage unit 212 is updated (FIG. 11: t8). (See t9).

  Proceeding to FIG. Next, when the user operates the operation unit 255 of the communication device 20, first, the communication control unit 253 of the communication device 20 transmits a control signal Sc including setting information stored in the storage unit 212 to the wireless communication unit 252. To send from. Accordingly, when the control unit 101 of the speaker device 10-3 receives the control signal Sc, since it is in the individual setting mode at this time, the volume value Vc (“20%” indicated by the setting information included in the control signal Sc is set. ”), The individual volume value Vp3 indicated by the individual setting information stored in the storage unit 111 of the speaker device 10-3 is updated (see t10 in FIG. 11), and the volume value Vc is changed to the individual volume value Vp3. Copied. As a result, the control unit 101 of the speaker device 10-3 has an amplification factor corresponding to the product (“12%”) of the overall volume value Va (“60%”) and the individual volume value Vp3 (“20%”). Set in the amplification unit 103. Accordingly, the volume level of the audio signal Sin to be emitted is in accordance with the overall volume value Va and the individual volume value Vp3. Here, since the other speaker devices 10-1 and 10-2 are set to the setting stop mode, the overall setting information and the individual setting information are not updated even when the control signal Sc is received.

  Further, since there is no speaker device next to the speaker device 10-3 in the connection list, the communication control unit 253 has selection information and transmission request information indicating the entire speaker device in order to select the entire speaker device as a setting target. The included request signal Sr is transmitted from the wireless communication unit 252. Accordingly, when the control unit 101 of all the speaker devices 10-1, 10-2, and 10-3 receives and acquires the request signal Sr, the control unit 101 switches to the overall setting mode, and the speaker device 10-3 emits light. The power supply to the unit 180 is stopped, and the light emitting unit 180 does not emit light. Further, the control units 101 of all the speaker devices 10-1, 10-2, and 10-3 read out the entire setting information stored in the storage unit 111, and include a feedback signal that includes the read out entire setting information as setting information. Sf is output to the wireless communication unit 151 and transmitted to the communication device 20.

  Here, the entire volume value Va indicated by the setting information included in the feedback signal Sf is the same “60%” regardless of which speaker device 10 transmits the communication device 20. The feedback signal Sf may be received. Therefore, you may make it designate the speaker apparatus 10 which transmits the feedback signal Sf by transmission request information. In this example, the feedback signal Sf from the speaker device 10-1 is illustrated as being received by the communication device 20. Therefore, in FIG. 10, the description of communication of the feedback signal Sf in the speaker devices 10-2 and 10-3 is omitted.

  Then, the control unit 211 of the communication device 20 updates the volume value Vc indicated by the setting information stored in the storage unit 212 so that the entire volume value Va indicated by the setting information included in the received feedback signal Sf is obtained. (See FIG. 11: t11), the entire volume value Va is copied to the volume value Vc. Thereafter, if the user continues each operation, the same volume is repeated from t0 in FIG. 7, and the entire volume value Va and the individual volume values Vp1, Vp2, and Vp3 can be set. In this example of operation, the individual setting information stored in the storage unit 111 may be updated at any time by the operation of the operation unit 110 in the speaker device 10, but it is newly acquired by acquiring the control signal Sc. The individual setting information is updated according to the setting information included in the control signal Sc.

  Thus, in the audio system 1 according to the embodiment of the present invention, when the user carrying the communication device 20 moves into the communication range of the speaker device 10, the speaker device 10 and the communication device 20 are wirelessly communicated. The audio signal Sin reproduced in the portable audio device 21 of the communication device 20 is emitted from the sound emitting unit 120 of the speaker device 10 connected. When the plurality of speaker devices 10-1, 10-2, 10-3 and the communication device 20 are connected, the user can easily perform a plurality of remote operations by operating the operation units 213 and 255 of the communication device 20. The overall volume value Va of the entire speaker apparatus can be controlled, and the individual volume values Vp1, Vp2, and Vp3 of the speaker apparatuses 10-1, 10-2, and 10-3 can be controlled.

  As mentioned above, although embodiment of this invention was described, this invention can be implemented in various aspects as follows.

<Modification 1>
In the embodiment described above, the overall volume value Va indicated by the overall setting information stored in the storage unit 111 of the speaker device 10, the individual volume value Vp indicated by the individual setting information, and the storage unit 212 of the communication device 20 are stored. The volume value indicated by the setting information is the same, and both take values from “0” to “255”, but may be different. For example, in the communication device 20, the volume value is designated in 256 steps from “0” to “255”, and in the speaker device 10, the volume value is designated in 52 steps from “0” to “51”. Also good.

  In this case, the control unit 101 of the speaker device 10 stores a conversion table indicating the relationship between reception parameters and conversion parameters as shown in FIG. When the control unit 101 acquires the control signal Sc received from the communication device 20, the control unit 101 refers to the conversion table, treats the volume value indicated by the setting information included in the control signal Sc as a reception parameter, and sets the corresponding conversion parameter. The overall volume value Va indicated by the overall setting information stored in the storage unit 111 or the individual volume value Vp indicated by the individual setting information is updated so that the indicated volume value is obtained.

  On the other hand, when the control unit 101 acquires an operation signal by operating the operation unit 110, the individual volume value indicated by the individual setting information stored in the storage unit 111 is updated according to the operation signal, as in the embodiment. Then, the control unit 101 treats the individual volume value Vp indicated by the individual setting information stored in the storage unit 111 as a conversion parameter, and recognizes the volume value indicated by the corresponding reception parameter as the volume value indicated by the setting value of the feedback signal Sf. To do.

  Here, when the conversion parameter is “2”, the volume value indicated by the corresponding reception parameter is a plurality of volume values indicated by the corresponding reception parameter, as in the case where the volume value is indicated by “6” to “10”. Is set in advance so that one of the values is selected. In this example, a median value “8” from “6” to “10” is selected. . Note that this selection may be set so as to be changed depending on the update mode. That is, when the control unit 101 updates the volume value Vp indicated by the individual setting information stored in the storage unit 111 according to the operation signal, for example, the minimum value (“6” in the above example). ) Is selected and updated so as to decrease the individual volume value Vp, for example, the maximum value (“10” in the above example) may be selected.

  In this way, even when the range and step in which the change of the volume value in the operation unit 213 of the communication device 20 can be instructed is different from the range and step in which the change of the volume value in the operation unit 110 of the speaker device 10 can be instructed. The user can give an instruction to change the volume value by an operation without feeling uncomfortable.

<Modification 2>
In the above-described embodiment, the audio signal Sin is transmitted from the communication device 20 to the speaker device 10 and is acquired by receiving the audio signal Sin by the wireless communication unit 151 of the speaker device 10. However, the audio signal Sin is acquired. May be performed by another method. In this case, as illustrated in FIG. 14, the speaker device 10 </ b> A including the audio signal processing device 100 </ b> A having the input unit 105 that acquires the audio signal and inputs the audio signal to the amplification unit 103 may be used. The input unit 105 may have an input terminal to which the audio signal Sin is input, and may acquire the audio signal Sin input from the input terminal, or a musical sound generating means (not used) for generating the audio signal Sin. In this case, the audio signal Sin may be acquired from the musical sound generating means.

  In this way, the portable audio device 21 of the communication device 20 does not need to output the audio signal Sin, and when the user carrying the communication device 20 has moved within the communication range of the speaker device 10, The audio signal Sin acquired by the input unit 105 of the speaker device 10 is emitted from the sound emitting unit 120. In this case, the user can use the communication device 20 like a remote control that can change the sound volume to be emitted.

<Modification 3>
In the embodiment described above, the speaker device 10 includes the audio signal processing device 100, and in the amplification unit 103 of the audio signal processing device 100, the overall volume value Va indicated by the overall setting information and the individual volume value indicated by the individual setting information. The audio signal Sin is amplified at an amplification factor corresponding to Vp. However, the audio signal Sin is not limited to the amplifying unit 103. When power is supplied, the entire parameter and individual setting information indicated by the entire setting information indicate the audio signal Sin. It may be a signal processing unit that performs signal processing (for example, equalizing processing, reverberation processing, etc.) according to individual parameters. For example, when performing equalizing processing as signal processing, the overall parameters indicated by the overall setting information and the individual parameters indicated by the individual setting information may indicate frequency characteristics, and when performing reverberation processing, The overall parameter indicated by the setting information and the individual parameter indicated by the individual setting information may be a reverberation time or the like.

<Modification 4>
In the embodiment described above, as shown in FIGS. 8, 9, and 10, when the user operates the operation unit 255 of the communication device 20, the control signal Sc for updating the individual setting information related to the speaker device 10. Is transmitted from the communication device 20 and the feedback signal Sf related to the individual setting information is transmitted from the speaker device 10 when the individual setting mode is set. However, the transmission timing is not limited to this mode. . For example, as shown in FIG. 15, the control signal Sc is transmitted when the operation unit 213 of the communication device 20 is operated, and the feedback signal Sf is transmitted when the operation unit 110 of the speaker device 10 is operated. May be.

  The transmission of the feedback signal Sf from the speaker device 10 may be realized by the communication device 20 making an inquiry to poll the setting information related to the speaker device 10 at a predetermined interval. Specifically, it is performed as follows. First, the communication device 20 transmits an inquiry signal indicating whether the setting information has been updated from the previous inquiry by the operation of the operation unit 110 from the wireless communication unit 252 to the speaker device 10 under the control of the communication control unit 253. . When the inquiry signal is received by the speaker device 10, the control unit 101 of the speaker device 10 is stored in the storage unit 111 by the operation of the operation unit 110 between the reception of the previous inquiry signal and the current inquiry signal. If the updated setting information is updated, a response signal indicating that is output to the wireless communication unit 151 to be transmitted to the communication apparatus 20.

  When the communication device 20 receives the response signal, the wireless communication unit 252 transmits a transmission request signal indicating a request for transmitting the setting information related to the speaker device 10 to the speaker device 10 under the control of the communication control unit 253. When the transmission request signal is received by the speaker device 10, the control unit 101 of the speaker device 10 reads the setting information stored in the storage unit 111 and sends a feedback signal Sf including the setting information to the wireless communication unit 151. To be transmitted to the communication device 20. As described above, when the operation unit 110 of the speaker device 10 is operated, the communication device 20 receives the feedback signal Sf in response to a polling inquiry performed at a predetermined interval. This is merely an example, and the feedback signal Sf may be output in response to the inquiry signal regardless of whether or not the operation unit 110 is operated.

  FIG. 15 is an explanatory diagram when the process from t1 to t3 shown in FIG. 10 is processed according to this example. Since the process up to t2 is the same as the process of the embodiment, the description thereof is omitted, and the process after t2 will be described below with reference to FIGS. FIG. 16 corresponds to a part of FIG. 11 and relates to the volume value Vc indicated by the setting information that changes in accordance with the processing of this example shown in FIG. 15, the volume value Va indicated by the overall setting information, and the speaker device 10-1. It is explanatory drawing which shows the individual volume value Vp1 which individual setting information shows.

  When the user is instructed to change the volume value Vc by operating the operation unit 213 of the communication apparatus 20, the control unit 211 indicates the volume value indicated by the setting information stored in the storage unit 212 in response to the instruction. Vc is updated, and a control signal Sc including the setting information is transmitted. Here, the speaker device 10-1 is in the individual setting mode, and the speaker devices 10-2 and 10-3 are in the setting stop mode. When the control unit 101 of the speaker device 10-1 in the individual setting mode receives and acquires the control signal Sc, the control unit Sc uses the individual volume value Vp <b> 1 indicated by the individual setting information stored in the storage unit 111. The volume value Vc indicated by the included setting information is updated, and an amplification factor according to the setting information is set for the amplification unit 103.

  On the other hand, when the operation unit 110 of the speaker device 10-1 set to the individual setting mode is operated to change the individual volume value Vp1, the control of the speaker device 10-1 is performed according to the instruction. The unit 101 updates the individual volume value Vp1 indicated by the individual setting information stored in the storage unit 111, and sets the amplification factor according to the entire setting information and the individual setting information in the amplifying unit 103. Further, the speaker device 10 transmits a feedback signal Sf including the individual setting information as setting information to the communication device 20 in response to a polling inquiry from the communication device 20. Accordingly, when the control unit 211 of the communication apparatus 20 receives and acquires the feedback signal Sf, the individual volume indicated by the setting information included in the feedback signal Sf indicates the volume value Vc indicated by the setting information stored in the storage unit 212. Update to be the value Vp1. Therefore, regardless of which one of the operation unit 213 of the communication device 20 and the operation unit 110 of the speaker device 10-1 is operated, the volume value Vc indicated by the setting information related to the communication device 20 and the individual setting related to the speaker device 10-1. The individual volume value Vp1 indicated by the information is the same value (see FIG. 16: t2 → t3 ′). Here, when the operation unit 110 of the speaker devices 10-2 and 10-3 set to the setting stop mode (the same applies to the overall setting mode) is operated, the speaker devices 10-2 and 10-3, respectively. The individual setting information stored in the storage unit 111 is updated and the setting of the amplification factor is changed. The feedback signal Sf related to the update of the individual setting information is not set until the next individual setting mode is set. Do not send.

  In this way, the audio signal Sin reproduced in the portable audio device 21 is output from the sound emitting unit 120 of the speaker device 10 at a volume corresponding to the overall volume value Va indicated by the overall setting information and the individual volume value Vp indicated by the individual setting information. Sound is emitted. These volume values can be changed by operating the operation unit 213 of the communication device 20 or the operation unit 110 of the speaker device 10. In either operation, the display unit 214 of the communication device 20 It is possible to display the current entire volume value Va or individual volume value Vp according to the entire volume value Va or individual volume value Vp that can be changed by operating the operation unit 213 of the communication device 20. That is, among the overall volume value Va and the individual volume value Vp that specify the amplification factor to be set in the amplification unit 103 in the speaker device 10, a volume value that can be currently changed according to the operation of the operation unit 213 of the communication device 20, The communication device 20 can be synchronized so that the volume value Vc specifying the display content of the display unit 213 matches.

  Note that the timing at which the control signal Sc and the feedback signal Sf are transmitted and received is that the speaker device 10 is instructed to change the individual volume value Vp or the communication device 20 is instructed to change the volume value Vc. 10, the volume value that can be changed in accordance with the operation of the operation unit 213 of the communication device 20 among the entire volume value Va and the individual volume value Vp that specify the amplification factor to be set in the amplification unit 103 at 10. Although the correspondence relationship with the volume value Vc specifying the display content on the display unit 214 has shifted, the present invention is not limited to this timing. For example, while the speaker device 10 and the communication device 20 are connected by wireless communication, the control signal Sc and the feedback signal Sf may be transmitted and received at predetermined intervals.

<Modification 5>
In the above-described embodiment, when the connection by the wireless communication between the speaker device 10-1 and the communication device 20 is first started, first, the entire setting information stored in the storage unit 111 of the speaker device 10-1 is stored. The volume value Vc indicated by the setting information stored in the storage unit 212 of the communication device 20 has been updated so that the overall volume value Va is the reference, and the storage device 212 stores the volume value Vc. The volume value indicated by the overall setting information stored in the storage unit 111 of the speaker device 10-1 with reference to the volume value Vc indicated by the setting information stored in the unit 212 (volume value Vc at the time of connection by wireless communication) Va may be updated. In other words, the overall volume value Va related to the speaker device 10-1 and the volume value Vc specifying the display content of the display unit 214 in the communication device 20 when controlling the overall volume value Va are synchronized in correspondence. Just take it.

<Modification 6>
In the embodiment described above, when the connection by the wireless communication between the speaker device 10 and the communication device 20 is disconnected, the entire volume value Va indicated by the entire setting information stored in the storage unit 111 of the speaker device 10 and the individual setting information The individual volume value Vp indicated by may be updated to a preset volume value. Similarly, the volume value Vc indicated by the setting information stored in the storage unit 212 of the communication device 20 may be updated to a preset volume value.

  Here, the volume value Vc indicated by the setting information stored in the storage unit 212 of the communication device 20 is first updated after the connection by the wireless communication between the speaker device 10 and the communication device 20 is started. The previous volume value is stored as initial setting information in the storage unit 212. When the wireless communication between the speaker device 10 and the communication device 20 is disconnected, the setting information stored in the storage unit 212 indicates The volume value Vc may be updated to the volume value indicated by the initial setting information. In this way, it is possible to easily return to the volume value before the connection is started after the connection by the wireless communication between the speaker device 10 and the communication device 20 is disconnected.

<Modification 7>
In the embodiment described above, when the entire speaker device is selected as a setting target, the control unit 211 of the communication device 20 acquires the setting information included in the feedback signal Sf, and the acquired setting information is Although the volume value Vc indicated by the setting information stored in the storage unit 212 has been updated according to the indicated overall volume value Va, the acquisition of the setting information may not be based on reception of the feedback signal Sf. For example, if the entire setting information indicating the entire volume value Va is stored in the storage unit 212 of the communication device 20 or stored in the communication control unit 253, instead of using transmission / reception of the request signal Sr including the transmission request information, What is necessary is just to acquire the whole setting information memorize | stored in the communication apparatus 20, and to update the volume value Vc which the setting information memorize | stored in the memory | storage part 212 shows.

  The total volume value Va stored in this way is the state in which the specific speaker device is selected from the state in which the entire speaker device is selected as the setting target, or the wireless communication between all speaker devices 10 and the communication devices 20. When the connection by communication is changed to a disconnected state, the volume value Vc indicated by the setting information stored in the storage unit 212 may be read and the volume value Vc may be used.

<Modification 8>
In the embodiment described above, the selection of the entire speaker device or the specific speaker device as the setting target and the specification of the specific speaker device are both performed by operating one operator of the operation unit 255. It is also possible to provide a child so that the entire speaker device or a specific speaker device as a setting target can be operated by an operator different from the specification of the specific speaker device.

  In this way, even after all the speaker devices 10 in the connection list are specified as specific speaker devices, they can be specified again from the speaker devices 10 in the connection list. In other words, the selected state of the specific speaker device can be maintained by preventing the entire speaker device from being selected as the setting target. Further, even if not all the speaker devices 10 in the connection list are specified as the specific speaker device, the entire speaker device can be selected as the setting target.

<Modification 9>
In the embodiment described above, the speaker device 10 is configured to emit light in the light emitting unit 180 in order to notify that the own device is specified and is in the individual setting mode. However, the notification may be made in various modes such as sound, vibration, and movement. For example, in the case of notification by vibration, a vibration unit having a vibrator that vibrates the speaker device 10 when power is supplied may be provided instead of the light emitting unit 180.

<Modification 10>
In the embodiment described above, the wireless communication unit 151 of the speaker device 10 is provided with a detection unit that detects the strength of communication radio waves from the communication device 20, and the control unit 101 acquires the detection result and detects the detected communication radio wave intensity. Depending on, the amplification factor set in the amplification unit 103 may be changed. For example, as the detected communication radio wave intensity decreases, the distance between the speaker device 10 and the communication device 20 increases. Therefore, the amplification factor set in the amplifying unit 103 is changed to increase, and the distance is increased. The sound volume heard by the user carrying the communication device 20 may be kept small even when the user is away from the terminal. As described above, the control unit 101 detects the overall volume value Va indicated by the overall setting information stored in the storage unit 111 and the individual volume value Vp indicated by the individual setting information with respect to the amplification unit 103 by the detection unit. The amplification factor may be set according to the strength of the communication radio wave.

  Note that the communication control unit 152 may determine whether or not to connect using a condition according to the strength of the communication radio wave detected by the detection unit as a connection condition and a disconnection condition. For example, the connection condition may be that the strength of the communication radio wave from the communication device 20 that has established the wireless communication is equal to or higher than a preset threshold value, and the connection condition is less than the preset threshold value. It may be a condition.

  In this way, the communication control unit 152 can increase or decrease the set threshold value in accordance with an operation of an operation unit (not shown) without changing the intensity of the radio communication radio wave, so that the speaker device 10 And the communication device 20 are connected by wireless communication, and the range from the speaker device 10 can be adjusted. If the control signal Sc can be transmitted and received even before the speaker device 10 and the communication device 20 start connection by wireless communication, the threshold value is increased or decreased according to the control signal Sc. You may do it. For example, the threshold value may be decreased as the volume value Vc indicated by the setting information included in the control signal Sc increases, and the distance that the speaker device 10 and the communication device 20 can be connected by wireless communication may be increased. .

<Modification 11>
In the above-described embodiment, the operation unit 110 of the speaker device 10 instructs the change of the individual volume value Vp by outputting an operation signal corresponding to the operation to the control unit 101. A terminal may be provided, and a change in the volume value Vp may be instructed by outputting a signal instructing the change in the individual volume value Vp from an external device connected to the connection terminal to the control unit 101. Further, in the case of the configuration of the speaker device 10 as shown in the modification example 2, an external device that outputs the audio signal Sin acquired by the input unit 105 and an external device that outputs a signal instructing to change the volume value May be the same device.

<Modification 12>
In the above-described embodiment, the connection condition for starting connection by wireless communication between the speaker device 10 and the communication device 20 is transmitted from the communication device 20 in response to the connection request signal transmitted from the speaker device 10. However, other conditions may be used. For example, the connection condition may be that wireless communication is established between the speaker device 10 and the communication device 20 without performing transmission / reception of a connection request signal and a connection response signal.

  As another example, it is assumed that the connection relationship between the connection request signal and the connection response signal is reversed, and the communication device 20 transmits the connection request signal and receives it at the speaker device 10, and the speaker device 10 responds to it. Then, the connection response signal may be transmitted and received by the communication device 20. Then, the connection condition may be that the communication device 20 receives a connection response signal indicating connection permission. In this case, the communication control unit 253 of the communication device 20 may determine whether to connect depending on whether the connection condition is satisfied.

  On the other hand, regarding the disconnection condition, not only the wireless communication cannot be established but also other conditions may be used. For example, the disconnection condition may be that the audio signal Sin is not received from the communication device 20 connected by wireless communication for a preset time, for example, 10 minutes. In addition, in the control signal Sc transmitted from the communication device 20, the state of the portable audio device 21 such as information set in advance (for example, the remaining battery level of the portable audio device 21 is equal to or less than a predetermined amount or the sleep mode is entered). It is good also as a cutting condition that the control part 101 detected that the information which shows) was included.

<Modification 13>
In the embodiment described above, when the speaker device 10 and the communication device 20 are connected by wireless communication, the control unit 101 of the speaker device 10 starts supplying power from the power supply unit 102 to the amplification unit 103. However, after the speaker device 10 and the communication device 20 are connected by wireless communication, when the control signal Sc including information on the preset contents is further received from the communication device 20, the control unit 101 The supply of power from the supply unit 102 to the amplification unit 103 may be started.

  Here, the preset content information may indicate a volume value, for example, like the setting information in the embodiment, or playback generated by an operation of playing back an audio signal in the portable audio device 21. It may be information indicating an operation. In this way, even if the speaker device 10 and the communication device 20 are connected, the speaker device 10 is not used until the user performs a preset operation on the operation unit 213 of the portable audio device 21. Therefore, when the user carrying the communication device 20 only passes near the speaker device 10, the sound is not unnecessarily emitted. You can also.

<Modification 14>
In the embodiment described above, the determination based on the evaluation of the identification information in the communication control unit 253 of the communication device 20 is performed based on the group ID set in advance and the group ID indicated by the identification information included in the connection request signal received from the speaker device 10. However, another method may be used. For example, the following may be used.

  For example, the communication control unit 253 stores a list indicating connectable identification information in advance, compares the list with the identification information included in the connection request signal, and if there is matching identification information, Then, if there is no identification information that coincides with the determination, it may be determined that the connection is not established.

  Further, this determination may be performed by the user operating the operation unit 213 to determine whether or not to connect. In this case, the identification information included in the connection request signal is output to the portable audio device 21 via the interfaces 251 and 216, and a display according to the output identification information, for example, wireless communication is established and is a connection candidate. A display for specifying the speaker device 10, for example, a device ID or the like is displayed on the display unit 214. Then, the user confirms this display and operates the operation unit 213 to determine whether or not to connect to the speaker device 10 that is a connection candidate. Information indicating this determination is output to the communication module 25 via the interfaces 216 and 251 so that the communication control unit 253 may determine whether or not to connect to the speaker device 10.

<Modification 15>
In the above-described embodiment, the operation of the communication device 20 in the state where the portable audio device 21 and the communication module 25 are connected has been described, but when the portable audio device 21 and the communication module 25 are not connected. The communication module 25 does not operate, and even if the communication device 20 falls within the communication range of the speaker device 10, wireless communication is not established.
