Background
The microphone can convert external sound and vibration signals into electric signals through an acoustoelectric conversion process, so that the sound is acquired and identified.
At present, in some vehicles or other automatic control devices, in order to sense vibration and impact caused by the outside, detection can be generally carried out by arranging a microphone. When an object is impacted on the vehicle, the vibration of the sound wave is transmitted to the microphone, and is detected and identified by the microphone. Generally, the microphone can convert the vibration that inside vibrating diaphragm received into electric capacity or inductance change, and when there was sound wave vibration in the external world, the sound wave can be through getting into inside the microphone and promoting the vibrating diaphragm and produce the deformation, and the electric capacity that the microphone formed or inductance will change this moment to produced the voltage change along with the sound wave change, can discern the sound wave change through reading voltage this moment.
However, when the microphone collects the sound wave vibration generated by external impact, the vibration is transmitted to the microphone due to the large energy of the external vibration, and the diaphragm inside the microphone generates too large amplitude, so that the original information is lost, and the sound cannot be accurately detected and restored.
