The microphone indication information may have multiple representations in practical applications, and will be described in detail in the following embodiments. 102. The walkie-talkie selects a corresponding target microphone according to the microphone indication information.

After the interphone obtains the microphone indication information, the target microphone corresponding to the microphone indication information may be selected according to the microphone indication information.

103. The walkie-talkie uses the target microphone for audio collection.

After the walkie-talkie selects the corresponding target microphone, the target microphone can be used for audio acquisition.

In this embodiment, the interphone can have at least two microphones, and can select a corresponding target microphone according to the microphone indication information, so that the target microphone is used for audio collection, so in practical applications, the interphone can select each microphone according to actual needs. The target microphone is used for audio collection, so it can provide users with more choices;

In practical applications, the microphone indication information obtained by the walkie-talkie can have multiple manifestations, which are described below:

1. The microphone indication information is the selection information input by the user:

In this embodiment, the walkie-talkie can use the selection information input by the user as the microphone indication information, so the user can choose which microphone to use for the call and the recording. For details, please refer to FIG. 2, another embodiment of the audio collection control method of the walkie-talkie of the present invention. Includes:

201. The walkie-talkie displays a microphone selection interface to the user;

In this embodiment, the walkie-talkie can display the microphone selection interface to the user through the display screen, for example, the user can display [using the front microphone] and [using the rear microphone] for the user to select.

It should be noted that the foregoing step 201 is not a mandatory step. In practical applications, the walkie-talkie may not display the microphone selection interface on the display screen, but directly set the [use front microphone] and [use the rear microphone] at the keyboard. 】 button, the user can select by pressing the button.

Alternatively, the walkie-talkie can also be set in the built-in software program so that the user can select a microphone when inputting a specific command through the keyboard. For example, when the user inputs *#back#, the rear microphone can be selected. There is no limit here.

202. The walkie-talkie receives the selection information input by the user; After the user inputs the selection information, the walkie-talkie can receive the selection information sent by the user, and the selection information is used as the microphone indication information, and the selection information includes the identifier of the microphone that the user currently wishes to use.

For example, if the user inputs *#back#, the walkie-talkie can know that the microphone that the user currently wants to use is only "back".

203. The walkie-talkie uses the microphone that the user currently wants to use as the target microphone;

In this embodiment, when the walkie-talkie determines the identifier of the microphone that the user currently wants to use, the microphone that the user wishes to use can be queried according to the identifier.

It should be noted that, in this embodiment, a microphone can be disposed on the front and the back of the walkie-talkie, which are a front microphone and a rear microphone respectively. It can be understood that, in practical applications, the walkie-talkie can also have more microphones. , not limited to two, and the microphone that the user selects to use currently is not limited to one of them.

After the walkie-talkie uses the microphone that the user currently wants to use as the target microphone, the target microphone can be used for audio collection.

Specifically, the walkie-talkie may specifically include a microprocessor (MPU, Micro Processing Unit) and a codec (CODEC). The MPU and the CODEC are connected through a control channel and a voice channel, and each microphone is electrically connected to the CODEC.

After the target microphone is determined, the MPU can control the CODEC to turn on the electrical path of the target microphone through the analog switch, and temporarily turn off the electrical path of the other microphones, thereby achieving audio acquisition using the target microphone.

It should be noted that if the walkie-talkie is provided with two microphones, it is determined that the target microphone is a rear microphone. After the wind, the MPU can control the CODEC to use the rear microphone for audio acquisition in a mono mode.

The target microphone in each microphone performs audio acquisition, thus providing the user with more choices.

Second, the microphone indication information is the orientation detection information:

In this embodiment, the intercom can use the result of the azimuth detection as the microphone indication information, so the user does not need to actively select, but the result of the orientation detection by the intercom itself can determine which microphone to use for the call and recording, and the specific orientation detection mode. It can be divided into the following situations: (1), using the gravity sensor for orientation detection:
