The automobile ECU is the core of the automobile electronic control system, which obtains sound through the microphone and drives the actuator to operate after processing. The use of microphone heads is mainly in the following areas:
1. In Car Communication System
Single directional or noise cancelling microphone heads are used in the car phone module to convert sound signals into electrical signals through the amplifier of the ECU, and then transmit them to the communication network through the controller to ensure call quality.
2. Voice Control Function
The polar body microphone collects driver commands, and the ECU interprets the voice content and performs operations, such as adjusting windows, air conditioning, or starting navigation.
