Abstract

A microphone module, comprising a housing, a circuit board disposed on the housing, and a microphone disposed on the circuit board, a PIN pin is connected between the housing and the circuit board, the A first connection hole is formed on the circuit board, a second connection hole is formed on the housing, one end of the PIN pin is fixed to the first connection hole, and the other end is fixed to the second connection hole, the The first connection hole and the second connection hole are arranged at intervals, the PIN needle and the circuit board are fixed by soldering, and the distance between the solder and the second connection hole is not less than 1.5 times the width of the PIN needle , the microphone module of the present invention expands the deformation area of ​​the PIN pin by increasing the length of the PIN pin between the circuit board and the housing, so that the internal force (bending moment) at the welding point between the PIN pin and the circuit board is reduced, and the PIN pin is indirectly reduced. The stress amplitude and average stress of the needle can be improved to improve its fatigue resistance and avoid cracking.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted voice recognition, in particular to a vehicle-mounted microphone module. Background technique [0002] With the vigorous development of on-board electronic equipment, the danger of operating equipment during driving is also increasing. Therefore, most vehicles have begun to be equipped with microphone modules to recognize the driver's voice commands, freeing the driver's hands and eyes, and providing an important guarantee for driving safety. Assure. The basic composition of the existing microphone module includes a circuit board (PCB) and a microphone connected to the PCB, a voice recognition chip, a processor, etc. The microphone converts the driver's voice signal into an electrical signal and outputs it to the voice recognition chip. The chip compares and recognizes the received signals, and the processor generates corresponding control signals according to the recognition results of t...
