The external speaker can be electrically connected with the mobile terminal through the contact connected with the external speaker, so that the mobile terminal can transmit signal data to the external speaker.
The external loudspeaker is an external expansion device which can be detachably connected with the contact. The contact can have various structural modes, optionally, the contact can be a section of bare wire on a circuit board arranged in the mobile terminal, and the external speaker can be electrically connected with the mobile terminal through the section of wire; or, the contact may be a connection terminal, one end of the connection terminal is electrically connected to a circuit board disposed in the mobile terminal, and the other end of the connection terminal may be electrically connected to the external speaker.
Of course, the contact may also be used to connect other external expansion devices such as an external backup battery, and the embodiment of the present disclosure takes the example of the contact being connected with an external speaker as an example.
As shown in fig. 2, the method may include:
step 201, the audio playing apparatus obtains an instruction for playing audio data.
The audio data may be sound data in an audio file, and the audio file may be a local file stored in the mobile terminal or a network file obtained from a network in real time. When the user triggers an instruction to play the audio file, the audio playing device can correspondingly acquire the instruction to play the audio data corresponding to the audio file.
The mode of the user triggering the instruction to play the audio file may be various, and optionally, the instruction to play the audio file may be triggered by clicking a play button of the audio file, or the instruction to play the audio file may be automatically triggered by opening the audio file (opening the audio file is an instruction to play the audio file), which is not limited in this disclosure.
Step 202, the audio playing device obtains the enabling state of the at least two contacts, wherein the enabling state comprises enabled or not enabled.
If the starting state is started, the mobile terminal can transmit audio data to the external speakers connected with the at least two contacts through the at least two contacts; if the enabled state is not enabled, it indicates that the mobile terminal cannot transmit audio data to the external speakers connected with the at least two contacts through the at least two contacts.
In the embodiment of the present disclosure, the audio playing apparatus may be integrated in an application installed in the mobile terminal, and the application may be an application carried by the mobile terminal when the mobile terminal leaves a factory, or may be a third-party application. The audio playing device can be provided with a switch capable of changing the starting states of the at least two contacts, the switch can be arranged in a User Interface (UI) of an application program, the switching state of the switch can correspond to the starting states of the contacts, and the starting states of the contacts can be changed by triggering the switch. For example, when the switch is in the on state, the contacts are in the enabled state; when the switch is in the off state, the contacts are in the inactive state. Fig. 3 schematically shows a schematic diagram of a switch 31 disposed in a user interface 30 of an XX application, the XX application corresponds to a name of an application in which an audio playing device is integrated, and the embodiment of the disclosure is not limited herein, and the switch 31 may include a trigger button 32, and an on state and an off state of the switch 31 may be set by pressing the trigger button 32. Of course, the switch may also be presented in other forms in the user interface of the application program, and the disclosed embodiment is not limited herein.
Step 203, when the activation state of the at least two contacts is activated, the audio playing device determines a target contact of the at least two contacts, and the target contact is connected with an external speaker.
When the audio playing device obtains the enabling states of the at least two contacts and determines that the enabling states of the at least two contacts are enabled, the contact connected with the external speaker in the at least two contacts can be determined as a target contact. Optionally, the audio playing device may determine the enabling state of the at least two contacts according to the on state and the off state of the switch.
And step 204, the audio playing device controls the external loudspeaker connected with the target contact to play audio data.
The audio playing device outputs audio data to an external loudspeaker connected with the target contact point through the target contact point in the enabled state, so that the external loudspeaker plays the audio data.
Alternatively, the target contact may be multiple, that is, multiple external speakers may be electrically connected to the mobile terminal through the multiple target contacts, respectively.
For example, the target contact may include a first contact and a second contact, and a volume of the external speaker connected to the first contact is greater than a volume of the external speaker connected to the second contact.
Then, as shown in fig. 4, step 204 may include several sub-steps as follows:
substep 2041, the audio playing device obtains the playing volume of the audio data.
The playing volume of the audio data may be determined by the player volume and/or the system volume control in the mobile terminal, and optionally, the external speaker may also have a function of adjusting the playing volume: and adjusting the playing volume of the audio data played by the external loudspeaker. Optionally, the external speaker may be provided with a key or a knob for adjusting the playing volume, and the playing volume of the audio data played by the external speaker is controlled by adjusting the key or the knob. In the embodiment of the disclosure, the volume of the external speaker connected to the first contact is adjusted to be greater than the volume of the external speaker connected to the second contact.
And a substep 2042, when the playing volume of the audio data is lower than a first volume threshold, playing the audio data by the audio playing device through the external speaker connected with the first contact.
The external speaker connected with the first contact point can have larger playing volume of the audio data, and when the playing volume of the audio data is lower than the first volume threshold, the audio playing device can play the audio data through the external speaker with the larger playing volume of the audio data, so that the situation that the playing sound of the played audio data is too small can be avoided.
Under the certain circumstances of broadcast volume and/or system volume in mobile terminal, can adjust the size of the broadcast volume of audio data through the broadcast volume of control external speaker, practiced thrift mobile terminal's energy consumption: compared with the prior art that the playing volume and/or the system volume of the mobile terminal need to be increased to achieve the effect of playing outside, the method provided by the embodiment of the disclosure saves the energy consumption of the mobile terminal.
And a substep 2043, when the playing volume of the audio data is higher than the second volume threshold, playing the audio data by the audio playing device through the external speaker connected with the second contact.
The external speaker connected to the second contact may have a smaller audio data playing volume, and when the audio data playing volume is higher than the second volume threshold, the audio playing device may play the audio data through the external speaker having the smaller audio data playing volume, so that the external speaker may adjust the audio data playing volume, and the situation that the playing sound of the played audio data is too large to affect the use of the user is avoided.
When the playing volume of the audio data is between the first volume threshold and the second volume threshold, the audio playing device may select to play the audio data without through the external speaker or through any external speaker, which is not limited herein in the embodiments of the present disclosure.
For example, the first volume threshold is 65 db, the second volume threshold is 80 db, and when the audio playing device obtains the playing volume of the audio data as 40 db, the audio playing device plays the audio data through the external speaker connected to the first contact; when the audio playing device obtains that the playing volume of the audio data is greater than 90 decibels, the audio playing device plays the audio data through the external loudspeaker connected with the second contact; when the audio playing device obtains the playing volume of the audio data as 70 db, the audio playing device may not play the audio data through any external speaker.
The playing volume of the external speaker connected to the first contact and the playing volume of the external speaker connected to the second contact can be adjusted in advance by the user, so as to implement the method described in the sub-step 2042 and the sub-step 2043.
Wherein the first volume threshold is lower than the second volume threshold. The first volume threshold and the second volume threshold may be automatically set according to the playing volume of the external speaker, for example, the first volume threshold may be set as the volume value of the external speaker connected to the second contact, and the second volume threshold may be set as the volume value of the external speaker connected to the first contact.
For another example, in order to better meet the requirement of the volume of the audio data that the user wants to play, it may be configured that, when the difference between the playing volumes of the external speaker connected to the first contact and the external speaker connected to the second contact is greater than the preset threshold, the determining that the playing volume of the audio data is lower than the first volume threshold or higher than the second volume threshold as described in the foregoing sub-step 2042 and sub-step 2043 is performed.
Step 205, the audio playing device outputs the audio data to the built-in speaker and/or the earphone.
In the embodiment of the present disclosure, in addition to the audio data that can be output from the external speaker, the audio data can also be output to an internal speaker and/or an earpiece of the mobile terminal, so as to achieve a better sound playing effect of the mobile terminal.
Optionally, the at least two contacts may be distributed on the back of the mobile terminal, and a user may freely select to connect the external speaker with any one of the at least two contacts. Alternatively, as shown in fig. 5, which shows a schematic diagram of the back side of the mobile terminal M, when the mobile terminal M includes two contacts a1 and a2, the external speaker C1 and the external speaker C2 may be disposed in connection with the contact a1 and the contact a2, respectively, one contact a1 of the two contacts may be disposed at a first position B1 on the back side of the mobile terminal M, the first position B1 is a position corresponding to the internal speaker of the mobile terminal M, the other contact a2 of the two contacts is disposed at a second position B2 on the back side of the mobile terminal M, and the second position B2 is a position corresponding to the earpiece of the mobile terminal M.
Fig. 6 shows a schematic side view of a mobile terminal M, from which it can be seen more clearly that a contact a1 is arranged in a first position B1 in which a built-in speaker E is arranged, an external speaker C1 is arranged on a contact a1, a contact a2 is arranged in a first position B2 in which an earpiece D is arranged, and an external speaker C2 is arranged on a contact a 2.
When the target contact point is A1, the playing effect of the built-in loudspeaker E of the mobile terminal M can be enhanced; when the target contact point is A2, the playing effect of a receiver D of the mobile terminal M can be enhanced; when the target contacts are a1 and a2, the playing effect of the built-in speaker E and the earpiece D of the mobile terminal M can be enhanced at the same time. The target contact point can be freely selected by a user (by changing the starting states of at least two contact points and the position where the external loudspeaker is arranged), and the flexibility of playing audio data by the mobile terminal is improved.
By the arrangement, when the mobile terminal plays audio, the audio data can be played from the built-in loudspeaker and/or the receiver and the external loudspeaker at the same time, so that the playing volume of the mobile terminal playing the audio data is enhanced, the stereoscopic playing effect of playing the audio frequency by the mobile terminal can be enhanced, and the function of the external loudspeaker is further expanded.
It should be noted that, in the embodiments shown in fig. 5 and fig. 6, the built-in speaker E and the handset D of the mobile terminal are respectively located at the lower and upper positions of the mobile terminal M in the figures, and in other possible embodiments, the built-in speaker and the handset may be located at other positions. Correspondingly, the two contacts may also be located at other corresponding positions, and details of the embodiments of the disclosure are not described herein.
In summary, according to the audio playing method provided by the embodiment of the present disclosure, audio data is transmitted to the external speaker connected to the target contact, so that the external speaker can play audio, thereby solving the problem that in the related art, the external speaker connected to the contact is only used for implementing a voice intercom function, which results in a single function of the external speaker, and enriching the functions of the external speaker connected to the mobile terminal.
Alternatively, step 203 and step 204 describe a method for determining the target contact, in which the at least two contacts correspond to a switch, and the activation state of the at least two contacts can be changed simultaneously by activating the switch. Of course, in other possible embodiments, each of the at least two contacts may correspond to a switch, and the audio playing device may obtain the enabled states of the at least two contacts, respectively, and fig. 7 shows a method for the audio playing device to determine the target contact in this case, which may be used to replace the above step 203 and step 204, and the method for determining the target contact further includes:
step 301, the audio playing apparatus obtains an enabled state of each of the at least two contacts, where the enabled state includes enabled or disabled.
Step 302, the audio playing device determines a contact point, which is activated and connected with the external speaker, of the at least two contact points as a target contact point.
It should be noted that, when each of the at least two contacts corresponds to a switch, the audio playing apparatus obtains the respective enabling states of the at least two contacts, and then step 203 may further be: and when the switches of all the at least two contacts are closed, the enabling states of the at least two contacts are determined to be the non-enabling states. Of course, the audio playing apparatus may have other configurations, and the embodiment of the disclosure is not limited herein.
Alternatively, when the audio playing device is integrated into an application installed in the mobile terminal, the switch may be disposed in a user interface of the application, and the enabling state of each contact may be controlled by one switch, for example, fig. 8 shows that in the user interface 30 of the XX application, two switches 31 are disposed, and the enabling states of the first contact and the second contact may be controlled by pressing a trigger button 32 in each switch.
In other possible embodiments, the audio playing device may determine the target contact of the at least two contacts without acquiring the activation status of the at least two contacts: the audio playback device may be set to default to which contact the external speaker is connected, and then automatically set that contact as the target contact. After the audio playing device obtains the instruction for playing the audio data, the audio data can be directly input to the external speaker connected to the target contact for playing. The user connects the external speaker with any one of the at least two contacts through free selection, so that the playing function of the external speaker on the contact can be realized, and the flexibility of playing audio data by the mobile terminal is improved.
In summary, according to the audio playing method provided by the embodiment of the present disclosure, audio data is transmitted to the external speaker connected to the target contact, so that the external speaker can play audio, thereby solving the problem that in the related art, the external speaker connected to the contact is only used for implementing a voice intercom function, which results in a single function of the external speaker, and enriching the functions of the external speaker connected to the mobile terminal.
