Detailed Description
The embodiment of the invention provides an interphone audio acquisition control method and an interphone, which can effectively improve the conversation quality and the recording quality of the interphone.
Referring to fig. 1, an embodiment of the method for controlling audio acquisition of an intercom includes:
101. the interphone acquires microphone indication information;
in this embodiment, the intercom may obtain microphone indication information, where the microphone indication information is used to indicate which microphone should be used by the intercom for audio collection.
The microphone indication information may have various expressions in practical application, and will be described in detail in the following embodiments one by one.
102. The interphone selects a corresponding target microphone according to the microphone indication information;
after the interphone acquires the microphone indication information, a target microphone corresponding to the microphone indication information can be selected according to the microphone indication information.
103. The interphone uses the target microphone to perform audio acquisition.
And when the corresponding target microphone is selected by the interphone, the target microphone can be used for carrying out audio acquisition.
In this embodiment, the intercom may have at least two microphones, and may select a corresponding target microphone according to the microphone indication information, so as to use the target microphone to perform audio acquisition, so in practical application, the intercom may select the target microphone in each microphone according to actual requirements to perform audio acquisition, thereby providing more selection spaces for users;
in addition, when a certain microphone faces to the obstacle, the microphone which does not face to the obstacle can be selected to collect the audio, so that the communication quality and the recording quality can be effectively improved.
In practical applications, the microphone indication information acquired by the intercom may have a plurality of expression forms, which are described below:
firstly, microphone indication information is selection information input by a user:
in this embodiment, the intercom may use the selection information input by the user as the microphone indication information, so that the user may independently select which microphone to use for communication and recording, specifically referring to fig. 2, another embodiment of the intercom audio acquisition control method of the present invention includes:
201. the interphone displays the microphone selection interface to a user;
in this embodiment, the intercom may show the microphone selection interface to the user through the display screen, for example, it may show [ using the front microphone ] and [ using the rear microphone ] to the user for the user to select.
It should be noted that, the step 201 is not an essential step, and in practical applications, the intercom may also set buttons [ using a front microphone ] and [ using a rear microphone ] directly at the keyboard instead of displaying the microphone selection interface on the display screen, and the user may select the selection by pressing the buttons.
Alternatively, the intercom may also perform a certain setting in the built-in software program, so that the user can select the microphone when inputting a certain specific instruction through the keyboard, for example, the user can select the rear microphone when inputting the # back #, and the specific implementation manner is not limited herein.
202. The interphone receives selection information input by a user;
after the user inputs the selection information, the interphone can receive the selection information sent by the user and uses the selection information as the microphone indication information, wherein the selection information comprises the identification of the microphone which the user currently wants to use.
For example, if the user inputs # back #, the intercom may learn that the microphone that the user currently wishes to use is labeled "back".
203. The interphone takes a microphone which a user currently wants to use as a target microphone;
in this embodiment, when the intercom determines the identifier of the microphone that the user currently wants to use, the microphone that the user wants to use can be queried according to the identifier.
For example, after the intercom knows that the microphone currently desired to be used by the user is identified as "back", it can be queried that the microphone currently desired to be used by the user is the rear microphone, and the intercom can use the rear microphone as the target microphone.
It should be noted that, in this embodiment, both the front side and the back side of the intercom may be provided with one microphone, which is a front microphone and a back microphone, respectively, and it is understood that, in practical applications, the intercom may also have more microphones, which are not limited to two microphones, and the microphone that the user selects and wants to use at present is not limited to one of the microphones.
For example, the intercom may be provided with four microphones, respectively located at the top and bottom of the front side, and the top and bottom of the back side, and the user may input # front1& back1# when inputting the selection information, and then the intercom may select the microphone at the top of the front side and the microphone at the top of the back side as the target microphones.
There are many similar situations for the specific number of microphones and the selection manner, and this is not limited here.
204. The intercom uses the target microphone for audio acquisition.
When the interphone takes the microphone which the user currently wants to use as the target microphone, the target microphone can be used for audio acquisition.
Specifically, the intercom may specifically include a microprocessor unit (MPU) and a coder-decoder (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 switch on the electric path of the target microphone through the analog switch and temporarily close the electric paths of other microphones, so that the target microphone is used for audio acquisition.
It should be noted that, if the intercom has two microphones and the target microphone is determined to be the rear microphone, the MPU may control the CODEC to perform audio acquisition using the rear microphone in a mono mode.
If the interphone has multiple microphones and the target microphone is also multiple microphones, for example, the interphone has four microphones respectively located at the top and bottom of the front side and the top and bottom of the back side, and the target microphone is the microphone at the top of the front side and the microphone at the top of the back side, then the MPU can control the CODEC to use the microphone at the top of the front side and the microphone at the top of the back side in a stereo manner to perform audio acquisition.
In this embodiment, the intercom may have at least two microphones, and may select a corresponding target microphone according to a microphone that the user currently desires to use, so as to use the target microphone to perform audio acquisition.
Secondly, the microphone indication information is azimuth detection information:
in this embodiment, the intercom can use the result of the direction detection as the microphone indication information, so that the user does not need to actively select, but the result of the direction detection performed by the intercom itself can determine which microphone to use for the call and recording, and the specific direction detection method can be divided into the following cases:
(1) and using a gravity sensor to detect the orientation:
in this embodiment, the gravity sensor of the intercom can be used for detecting the direction, and which microphone is used for calling and recording is determined according to the detection result.
In practical applications, the gravity sensor can detect a multi-directional state, and the following description is divided into cases:

in this embodiment, the front and the back of the intercom may be provided with a microphone, which is a front microphone and a back microphone respectively, and when the result of the gravity sensing detection indicates that the intercom is horizontally placed, it indicates that one microphone is downward and the other microphone is upward, and at this time, the intercom may use the microphone horizontally upward as the target microphone.
For example, when the interphone is right side up, the front microphone can be selected as the target microphone, and when the interphone is back side up, the rear microphone can be selected as the target microphone.
It is understood that in practical applications, the intercom may have more microphones, and is not limited to two microphones, and the target microphone is not limited to one of the microphones.
For example, the intercom may be provided with four microphones, respectively located at the front top and bottom, and the back top and bottom, and when the intercom is front up, the microphone at the front top and the microphone at the front bottom may be selected as the target microphones, and when the intercom is back up, the microphone at the back top and the microphone at the back bottom may be selected as the target microphones.
304. The intercom uses the target microphone for audio acquisition.
In this embodiment, after the interphone determines that the microphone facing horizontally upwards is used as the target microphone, the target microphone may be used for audio acquisition.
Specifically, the intercom may specifically include an MPU and a 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 switch on the electric path of the target microphone through the analog switch and temporarily close the electric paths of other microphones, so that the target microphone is used for audio acquisition.
It should be noted that, if the intercom has two microphones and the target microphone is determined to be the rear microphone, the MPU may control the CODEC to perform audio acquisition using the rear microphone in a mono mode.
If the interphone has multiple microphones and the target microphone is also multiple microphones, for example, the interphone has four microphones respectively located at the top and bottom of the front and the top and bottom of the back, and the target microphone is the microphone at the top of the front and the microphone at the bottom of the front, then the MPU can control the CODEC to use the microphone at the top of the front and the microphone at the bottom of the front in a stereo manner to collect audio.

403. When the result of the gravity sensing detection indicates that the interphone is laterally placed, the interphone tries to collect through each microphone;
in this embodiment, when the intercom determines that the intercom is placed in the side direction through the gravity sensor, each microphone may be used to try to acquire the current sound source.
404. Selecting a microphone with the sound source signal intensity higher than a preset threshold as a target microphone by the interphone according to the attempted acquisition result;
in this embodiment, the intercom may specifically include an MPU and a CODEC, the MPU and the CODEC are connected through a control channel and a voice channel, each microphone is electrically connected to the CODEC, and after the acquisition is completed, the CODEC may acquire the intensity of the sound source signal of each microphone, so that a microphone with the intensity of the sound source signal higher than a preset threshold may be selected as the target microphone.
In practical applications, if two microphones are provided in the intercom, the microphone with the higher intensity of the sound source signal may be selected as the target microphone.
It is understood that the intercom may have more microphones, and is not limited to two microphones, and the target microphone is not limited to one of the microphones.
For example, if the intercom has four microphones, the microphone with the highest intensity of the sound source signal may be selected as the target microphone, or two or three microphones with higher intensity of the sound source signal may also be selected as the target microphone, which is not limited herein.
405. The intercom uses the target microphone for audio acquisition.

503. When the distance sensing detection result indicates that the distance between the interphone and the barrier is smaller than a preset value, the interphone takes a microphone on the surface back to the barrier as a target microphone;
in this embodiment, the intercom may detect the distance between the intercom and the obstacle through the distance sensor, and when the result of the distance sensing detection indicates that the distance between the intercom and the obstacle is smaller than a preset value, the microphone on the face facing away from the obstacle may be used as the target microphone.
In this embodiment, the front and the back of the intercom may be provided with a microphone, which is a front microphone and a back microphone, respectively, and when the distance sensing result indicates that the distance between the front of the intercom and the obstacle is too small, the intercom may use the back microphone on the back as the target microphone.
