<First Embodiment>
As shown in FIG. 1, the sound transmission system 1 of this embodiment is arrange | positioned in the building which has several rooms 10 (10A-10D). The drawings based on the embodiments are schematic. When each of a plurality of components having the same function is indicated, one alphabetic character is deleted at the end of the code. For example, each of the rooms 10A to 10D is referred to as a room 10.

  As will be described later, in the sound transmission system 1 shown in FIG. 1, the user 9 who was watching a program on the television receiver (television) 20 in the room 10 </ b> A that is the first area exits from the first area. In this case, the room 10D is passed through the room 10B and the room 10C. The user 9 in the room 10D is listening to the sound of the television receiver (television) 20 output from the sound output unit 40D of the room 10D.

Here, the room 10 is not limited to a room having a general meaning such as a living room, a kitchen, a bedroom, and a child room, and the room 10 includes a hallway, an entrance, a bathroom, a storage room, a toilet, and the like. This includes areas that are not clearly independent. A large room may be regarded as a plurality of rooms.
The number of rooms 10 is two or more, but in the sound transmission system 1, there are four rooms as shown in FIG.

  In the sound transmission system 1, a television 20 that is a sound source and a transmission unit 30 are arranged in a room 10 </ b> A. The television 20 outputs a video signal and a sound signal S. The video signal and the sound signal are output from the monitor 21 and the speaker 22 of the television 20.

  The sound signal S output from the television 20 is also transmitted to the transmission unit 30 by wire or wirelessly. The transmission unit 30 transmits the sound signal S output from the television 20. Although the transmission means of the transmission unit 30 may be wired, it is preferable to use wireless communication, particularly short-range wireless communication because the construction is simple. Note that the television 20 and the transmission unit 30 may be integrated. For example, the television 20 may have the function of the transmission unit 30 that wirelessly transmits the sound signal S.

  On the other hand, the sound output units 40 (40B to 40D) are arranged in the rooms (separate areas) 10B to 10D different from the first area (room 10A), respectively. Of course, it is not necessary that the sound output unit 40 is provided in every room in the building. Conversely, in another embodiment to be described later, the sound output unit 40 is also arranged in the first region 10A.

  As shown in FIG. 2, each of the sound output units 40 (40B, 40C, 40D) of the room 10 (10B, 10C, 10D) includes a speaker 42 (42B, 42C, 42D) and a human sensor 43 (43B). , 43C, 43D) and a switch unit 44 (44C, 44C, 44D).

  The speaker 42 includes an amplifier that amplifies the sound signal S as necessary. Since the transmission means of the transmission unit 30 of the sound transmission system 1 is wireless, the sound output unit 40 is a sound signal transmitted wirelessly. It has the receiving part 41 (41B, 41C, 41D) which receives S.

  The human sensor 43 detects that there is a user (human) 9 in the room 10. The human sensor 43 is, for example, an imaging device such as an ultrasonic sensor, an infrared sensor, or a CCD having an image processing function. The human sensor 43 may be set to detect only an adult, or may be set to detect only a specific user by a known face recognition function based on the image of the imaging device. .

  The switch unit 44 controls the receiving unit 41 and the speaker 42 so that the sound signal S transmitted from the television 20 can be output by the speaker 42 only when it is detected that the user 9 is in the room 10. A control unit comprising a processor and the like.

  As shown in FIG. 1, in the sound transmission system 1, only the sound output unit 40 in the room 10 where the user 9 is located outputs the sound signal S transmitted from the television 20. For example, when a user 9 who has been watching a television program in the living room (room 10A) on the first floor enters the room 10B in order to move to the child room (room 10D) on the second floor, the user 9 enters the sound output unit 40B. Can listen to the sound of TV programs. Next, when entering the room 10C, the sound output unit 40B of the room 10B stops outputting sound, and the user 9 can hear the sound of the television program output by the sound output unit 40C. As shown in FIG. 1, when the user 9 enters the room 10D, no sound can be heard in the room 10C, and the sound output from the sound output unit 40D can be heard in the room 10D. In addition, it is possible to automatically continue listening to the program sound on the way home.

  Note that the user 9 may activate the transmission unit 30 before the start of movement, or may be set so that the transmission unit 30 is automatically activated when the television 20 is activated. The sound transmission system 1 is convenient because it does not require complicated settings / operations. In addition, since no sound signal is output in the room 10 where no human 9 is present, energy saving is also excellent.

  As shown in FIG. 3, the television 20 (transmission unit 30) and the sound output unit 40 (40B to 40D) of the sound transmission system 1 are connected by wire or wireless via a GW (gateway) 30X that is a hub. May be.

Second Embodiment
Next, a sound transmission system 1A according to the second embodiment will be described with reference to FIG. In addition, since the sound transmission system of the following embodiment and a modification is similar to the sound transmission system 1 of 1st Embodiment, the same code | symbol is attached | subjected to the component of the same function, and description is abbreviate | omitted.

  As shown in FIG. 4, in the sound transmission system 1 </ b> A, lighting devices 50 (50 </ b> A to 50 </ b> D) are disposed in the respective rooms 10 (10 </ b> A to 10 </ b> D). The sound output unit 40 is disposed integrally with the lighting device 50. The sound transmission system 1A in which the sound output unit 40 is disposed in the lighting device 50 is referred to as a lighting system 2A. Note that the illumination device 50 and the sound output unit 40 may also be arranged in the room 10A.

  The sound transmission system 1 </ b> A (lighting system 2 </ b> A) has the effect of the sound transmission system 1, and the sound output unit 40 can obtain driving power from the in-home power wiring connected to the lighting device 50. For this reason, the sound transmission system 1A (illumination system 2A) is easy to dispose. For example, the sound transmission system 1A (illumination system 2A) can be arranged more easily by integrally disposing the sound output unit 40 inside the illumination device 50 disposed on the ceiling or wall. In addition, the atmosphere of the room 10 is not impaired by the arrangement of the sound output unit 40.

  It is particularly preferable that the sound output unit 40 can be retrofitted as an option of the lighting device 50. That is, it is preferable that the lighting device 50 includes a sound output unit connection unit that completes electrical connection when the sound output unit 40 is attached. After the lighting device 50 is installed, the sound output unit 40 can be arranged very easily and at low cost as necessary.

<Modification of Second Embodiment>
Next, 1B (illumination system 2B) of the modification of 2nd Embodiment is demonstrated using FIG. In the sound transmission system 1B (lighting system 2B), the sound output unit 40 detects that the person 9 is in the room 10 based on the ON / OFF state of the lighting device 50. The ON / OFF operation of the illumination device 50 is performed, for example, by a user 9 remote control operation.

  In the sound transmission system 1B, it is assumed that the person 9 is present in the room 10 where the lighting device 50 is ON. For this reason, the sound output unit 40 of the sound transmission system 1B does not require a human sensor. Even if the dimmable lighting device 50 is in the ON state, it may be regarded as not being in the ON state when the light is adjusted to a very dark state. When the lighting device 50 includes a human sensor, the sound output unit 40 may output the sound signal S based on the detection result of the human sensor of the lighting device 50.

  The sound transmission system 1B (illumination system 2B) has the effect of the sound transmission system 1A (illumination system 2A), is simple in structure, and is inexpensive.

<Third Embodiment>
Next, the sound transmission system 1C (illumination system 2C) of the third embodiment will be described with reference to FIG. In the sound transmission system 1C (lighting system 2C), the sound sources 20A and 20B and the transmission units 30A and 30B are arranged in two or more rooms 10A and 10B, respectively, and the sound output unit 40 in another room is at least one of the sound sources. The sound signal S transmitted from 20A and 20B is output. In other words, in the sound transmission system 1C, there are a plurality of first regions where the sound source 20 is arranged.

  Note that the sound output unit 40 including the illumination device 50 and the transmission unit 30A may also be arranged in the first region 10A.

  For example, the receiving unit 41C in the room 10C receives the sound signal SA transmitted from the transmitting unit 30A in the room 10A and the sound signal SB transmitted from the transmitting unit 30B in the room 10B. When the human sensor 44C detects the person 9, the sound signal SA and the sound signal SB are simultaneously output from the speaker 42C.

  In the room 10B, only the sound signal SA is output. However, for example, when the sound source 20 and the transmission unit 30 are also arranged in the room 10C, the sound signal from the room 10C is output in addition to the sound signal SA in the room 10B.

  The sound output unit 40 may be set so that the reproduction volumes of the plurality of sound signals are different, or may automatically change the sound signals to be output at predetermined time intervals.

  The sound transmission system 1C (lighting system 2C) has the effect of the sound transmission system 1A (lighting system 2A), and is more convenient.

<Modification of Third Embodiment>
Next, the sound transmission system 1D (illumination system 2D) of the modification of 3rd Embodiment is demonstrated using FIG. The sound transmission system 1D (illumination system 2D) includes a selection unit 60 (60C, 60D) that selects the sound source 20 output by the sound output unit 40 (40C, 40D).

  The selection unit 60 is, for example, a remote controller or a smart phone operated by the user 9 in the room 10C or the like. However, the selection unit 60 may automatically perform selection according to preset conditions, for example, time. For example, a sound signal from the TV 20A that is a sound source is selected during a time period when the TV 20 is broadcasting news, and a sound signal from the sound source 20B that is a music player is selected during other time periods. Also good.

  The sound transmission system 1D (lighting system 2D) has the effect of the sound transmission system 1C (lighting system 2C), and is more convenient.

<Fourth embodiment>
Next, the sound transmission system 1E (illumination system 2E) of the modification of 4th Embodiment is demonstrated using FIG. 8 and FIG. Note that FIG. 9 is a diagram for explaining the transmission path of the sound signal, and therefore, components not directly related to transmission are not shown. In the sound transmission system 1E (lighting system 2E), each sound output unit 40 (40B, 40C, 40D) has a transmission unit (30B, 30C, 30D) that transmits and relays the received sound signal.

  That is, as shown in FIG. 9, in the sound transmission system 1E, the transmission path of the sound signal is meshed. For example, the sound signal output from the transmission unit 30A is not only the route (D) but also the reception unit of the room 10D via the route (F)-(C) or the route (A)-(B)-(C). It is received by 41D.

  The room 10D is the final transmission path of the sound signal. For this reason, the transmission unit 30D of the room 10D does not need to transmit (relay) the received sound signal. That is, the transmission unit in a room in which the person 9 is detected, for example, a room in which the lighting device 50 is ON does not transmit the received sound signal.

  The sound transmission system 1E can simplify wiring for transmission when the transmission means is wired. When the transmission means is wireless, a low noise signal having the highest transmission efficiency, in other words, a strong signal strength is received. For example, when the floor on the second floor is a member that blocks radio waves, such as concrete, the radio wave output from the transmitting unit 30A of the first floor room 10A is difficult to reach the second floor room 10D. However, in the paths (A)-(B)-(C), since there is no member for blocking radio waves, the transmission distance is longer than that in the path (D), but the transmission efficiency is high.

  The sound transmission system 1E (illumination system 2E) has effects such as the sound transmission system 1A (illumination system 2A), and can transmit sound signals more efficiently.

<Fifth Embodiment>
Next, the sound transmission system 1F (illumination system 2F) of the modification of 5th Embodiment is demonstrated using FIG. In the sound transmission system 1F (illumination system 2F), the sound source 20F is a device that outputs a sound signal according to the operating state.

  For example, the sound source 20 </ b> F is a notification sound output unit that notifies the completion of washing of the washing machine 23. The sound source 20F outputs a notification sound from a speaker (vibrator) 42 disposed in the washing machine 23, and outputs a sound signal of the notification sound from a transmission unit (not shown).

  As shown in FIG. 10, a lighting device 50D is arranged in a room 10A of the sound transmission system 1F (illumination system 2F), and the transmission unit 30A and the reception unit 41A are part of the sound output unit 40A. . The sound signal of the notification sound from the washing machine 23 is received by the receiving unit 41A. Moreover, the sound output units 40B, 40C, and 40D may each include the transmission unit 30.

  The user 9 in the room 10D can hear a notification sound for notifying completion of washing of the washing machine 23 via the sound output unit 40D.

  Note that a device that outputs a sound signal according to the operating state is not limited to an audio device such as the washing machine 23 and the television 20, or a cooking device such as a microwave oven, and may be a device that outputs a notification sound. For example, a bath system that outputs a hot water completion sound may be used.

  In addition, when the sound output unit 40D outputs sound signals from a plurality of sound sources as in the sound transmission system 1C of the third embodiment, the sound output unit 40D prioritizes the notification sound over another sound. It is preferable to output, for example, output with a louder sound.

  The sound transmission system 1F (illumination system 2F) has the same effect as the sound transmission system 1A (illumination system 2A), and does not miss the notification sound output by the device.

<Sixth Embodiment>
Next, the sound transmission system 1G (illumination system 2G) of the modification of 6th Embodiment is demonstrated using FIG. In the sound transmission system 1G (illumination system 2G), the sound source 20 in the first area 10A displays a video corresponding to the sound signal, and the room 10A is based on the information of the sound output unit in the first area 10A. The device does not display an image when there is no human 9 in the screen.

  The television 20 is a sound source that outputs the sound signal S, and is a device that displays a video corresponding to the sound signal S on the monitor 21. As already described, according to the sound transmission system (illumination system) of the embodiment of the present invention, even when the user 9 is away from the room 10A in which the television 20 is disposed, the sound of the television 20 can be heard in another room. Can hear.

  However, even when there is no user 9 in the room 10A in which the television 20 is disposed, the video is displayed on the monitor 21 of the television 20, which is useless.

  In the sound transmission system 1G (lighting system 2G), a sound output unit 40A including a reception unit 41A, a transmission unit 30A, and a human sensor 43A is also provided in the room 10A.

  When the human sensor 43 </ b> A does not detect the human 9, the sound output unit 40 </ b> A controls the television 20 not to display the video signal on the monitor 21. For example, the sound output unit 40A controls to turn off the backlight of the monitor 21.

  The room 10A is a large room, and there is an obstacle between the user 9 and the monitor 21, and the sound output unit 40A does not display the video signal on the monitor 21 even when the user 9 cannot visually recognize the monitor 21. It is preferable to control as described above. That is, in the case of a large room in which a plurality of lighting devices are arranged in a room, one room may be regarded as being composed of a first area where a sound source is located and a room different from the first area. it can. Furthermore, when the presence of the user 9 is detected by the imaging device, the line-of-sight direction of the user 9 is detected by image processing, and when the user 9 has not seen the monitor 21 for a predetermined time or more, the television 20 becomes the monitor 21. You may control so that a video signal is not displayed.

  The sound transmission system 1G (illumination system 2G) has the effect of the sound transmission system 1A (illumination system 2A), and further, does not display an image on the monitor 21 without a human being viewed, and thus has excellent energy saving performance. It goes without saying that not only the video signal but also the output of sound from the speaker 22 of the television 20 may be stopped.

<Seventh embodiment>
Next, the sound transmission system 1H (illumination system 2H) of the modification of 7th Embodiment is demonstrated using FIG. In the sound transmission system 1H (illumination system 2H), the sound source is the microphone 20H arranged in the room 10A.

  For example, the microphone 20H in the child room 10A converts the cry of the infant 9A into a sound signal and outputs the sound signal.

  The user 9 can hear the cry of the infant 9 </ b> A through the sound output unit 40 that detects the presence of the human 9 in any room.

  The sound transmission system 1H (illumination system 2H) has the effect of the sound transmission system 1A (illumination system 2A), and can hear the cry of the infant 9A reliably in any room, so it is highly convenient. .

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention.
