- Commodity name: A2B Car Microphone Testing Solution
- Commodity ID: Car Microphone
The car microphone is the core component for car voice interaction (navigation, voice control, communication), active noise cancellation (ANC), and in car sound field acquisition. Its audio performance directly determines the speech recognition rate, noise resistance, and communication clarity. By using the high-performance audio analyzer independently developed by Aptec, combined with acoustic testing accessories such as electroacoustic testing interface, artificial mouth, standard microphone, and sound calibrator, the acoustic characteristics of the microphone can be tested.
The audio analyzer sends out a standard test signal, which is amplified by the power amplifier to drive the artificial mouth to produce sound. The DUT MIC collects the artificial mouth sound signal and transmits it back to the Master interface of the A2B module, which is then analyzed and displayed by the upper computer software.
