This system uses our own high-performance two-channel A2 audio analyzer and related acoustic test accessories, such as standard microphones, artificial mouths, etc., to achieve the performance index test of the microphone under test, such as sensitivity, frequency response, distortion curve, array Mai's consistency test.
In order to solve the problem that Apple products cannot be directly controlled on the market, this solution uses the development of a WIFI-based APP (named: APPForIphone) on the Apple ipod touch to assist the test, so as to achieve the ability to play different test signals according to different test items. Audio test Parameters: Headphone Total Harmonic Distortion, Headphone Frequency Response, Microphone Frequency Response / Smartness, Microphone Total Harmonic Distortion.
The main control board usually supports multiple working modes such as WIFI and Bluetooth, and parses MIC voice commands; The power amplifier board realizes voice playback of Smart speaker; The MIC board realizes voice command recording, usually recording 6-8 microphones simultaneously; Other auxiliary function boards such as buttons, LEDs, etc.
