To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is
Some embodiments of the present application, instead of all the embodiments.The application being usually described and illustrated herein in the accompanying drawings is implemented
The component of example can be arranged and be designed with a variety of different configurations.
Therefore, the detailed description of the embodiments herein provided in the accompanying drawings is not intended to limit below claimed
Scope of the present application, but be merely representative of the selected embodiment of the application.Based on the embodiment in the application, this field is common
Technical staff's every other embodiment obtained without creative efforts belongs to the model of the application protection
It encloses.
With reference to the accompanying drawing, it elaborates to some embodiments of the application.In the absence of conflict, following
Feature in embodiment and embodiment can be combined with each other.
Referring to Fig. 1, audio frequency apparatus test macro 1 includes audio frequency apparatus 10 and test equipment 20.Audio frequency apparatus 10 and test
The wireless communication connection of equipment 20.Test equipment 20 is for sending test signal to audio frequency apparatus 10 and playing testing audio.Sound
Frequency equipment 10 is used to start to test according to test signal.Analytic signal is exported according to testing audio, and analytic signal is sent to
Test equipment 20.Test equipment 20 judges whether testing audio equipment 10 is qualified according to analytic signal and testing audio.
Referring to fig. 2, audio frequency apparatus 10 includes first processing module 110 and at least one digital microphone 120.First processing
Module 110 is electrically connected at least one digital microphone 120.In audio frequency apparatus 10, including main microphon and secondary microphone.Its
In, main microphon is used for pickup.Secondary microphone is for reducing environmental noise, to ensure the pickup quality of main microphon.
First processing module 110 is used for the test signal sent according to test equipment 20, controls microphone to be tested and opens,
And control other microphones in addition to microphone to be tested and remain off, digital microphone include microphone to be tested and
Other microphones.
The testing audio that microphone to be tested is used to pick up the broadcasting of test equipment 20 obtains audio signal, and by audio signal
It is sent to first processing module 110.
For example, digital microphone 120 can be 3, e.g., MIC1, MIC2, MIC3.Based on one of digital microphone
Microphone, remaining 2 digital microphone are secondary microphone.Digital microphone 120 may be, but not limited to, YX-350M number wheat
The digital microphones such as gram wind, M8RF digital microphone, CT5000 digital microphone.
It should be noted that since digital microphone 120 cannot directly receive the test signal of the transmission of test equipment 20, because
This, needs to receive test signal by first processing module 110, by first processing module 110 according to test signal, directly control
Microphone to be tested is opened.
It should also be noted that, when testing one of microphone at least one digital microphone 120,
The microphone is microphone to be tested, and microphone to be tested is opened, remaining microphone remains off, i.e., only opens one every time
A microphone avoids interference of remaining microphone to microphone to be tested.After the completion of to test microphone test, at it
A microphone is opened in the remaining microphone without test as microphone to be tested, until all microphones are tested
Afterwards, audio frequency apparatus 10 is completed.
Continuation is illustrated by taking 3 microphones as an example, as shown in Figure 1,3 microphones are as follows: MIC1, MIC2 and MIC3.When
Microphone to be tested is MIC1, then MIC1 unlatching is tested, remaining microphone MIC2 and MIC3 are remained off.When right
After the completion of MIC1 test, a microphone is opened in microphone MIC2 and MIC3 not after tested and is tested, such as is opened
MIC2, MIC2 are test microphone, and MIC1 and MIC3 are closed.After completing test to MIC2, opens MIC3 and tested, MIC3
To test microphone, MIC1 and MIC2 are closed.After all microphone MIC1, MIC2 and MIC3 are tested, audio frequency apparatus 10 is complete
At test.
Optionally, the microphone opened in digital microphone 120 is test microphone, and the unlatching of digital microphone 120 is suitable
Sequence can be opened according to the sequence of microphone at least one digital microphone 120 numbered from small to large.

It crosses and swept-frequency signal is sent to audio player 220, audio player 220 plays out after picking up the swept-frequency signal, to be tested
Microphone picks up the swept-frequency signal of the broadcasting of audio player 220.Due in swept-frequency signal with the signal of different frequency range, with sweeping
Frequency signal tests microphone to be tested, ensure that microphone to be tested is tested under different frequency range signal, thus
Avoid the need for the complicated processes that test frequency is set one by one.
Audio player 220 can be, but be not limited only to the broadcasting of the audios such as artificial mouth, computer, plate, mobile terminal and set
It is standby.For example, can choose M300 type artificial mouth.
Second processing module 210 is also used to judge whether microphone to be tested is qualified according to testing audio and analytic signal,
And when determining all digital microphones qualification, the qualified test result of audio frequency apparatus 10 is obtained.When all digital wheats
Deposited in gram wind microphone test result be it is unqualified, then obtain the underproof test result of audio frequency apparatus 10.
Audio frequency apparatus test macro and method provided by the present application, test equipment 20 and the wireless communication of audio frequency apparatus 10 connect
It connects, test signal is sent to the first processing module 110 of audio frequency apparatus 10, first processing module 110 by Second processing module 210
According to the test signal, the microphone to be tested controlled in digital microphone 120 is opened, and is controlled in digital microphone 120
Remaining microphone remains off, i.e., only opens a digital microphone 120 every time.Second processing module 210 sends test
Audio, test microphone pick up the testing audio and obtain audio signal, since the audio signal of test microphone output is number
Signal obtains analytic signal, and parsing is believed therefore, it is necessary to which audio signal is sent to first processing module 110 to parse
Number it is sent to Second processing module 210, Second processing module 210 judges wheat to be tested according to testing audio and analytic signal
Whether gram wind is qualified.When all digital microphones 120 are qualified, test result is that audio frequency apparatus 10 is qualified.Pass through control
It tests microphone to open, remaining microphone remains off, and tests test microphone, the test microphone is by surveying
After examination, then remaining microphone that do not tested at least one digital microphone 120 is tested, until all digital microphones
Wind 120 is tested.The test to audio frequency apparatus 10 is completed in a testing process, is improved audio frequency apparatus 10 and is tested speed
Degree, improves factory efficiency.
