[0002] With the popularization of vehicles, the improvement of people's living standards, people's requirements for the sound effect in the car are higher and higher, the vehicle-mounted high-pitched loudspeaker is usually shrunk and clamped on the surface of the vehicle instrument desk, and the operator needs to stretch it to separate it from the surface of the vehicle instrument desk when maintaining the vehicle-mounted high-pitched loudspeaker, and the operator's skin is easily pinched after the vehicle-mounted high-pitched loudspeaker is loosened, so it is necessary to set an anti-pinch detection device in the vehicle-mounted high-pitched loudspeaker.

[0003] The existing vehicle-mounted high-pitched loudspeaker human body anti-pinch detection device mostly sets an electric telescopic rod, a driving motor, a pressure sensor and a micro-control switch at the bottom of the loudspeaker to control the lifting of the loudspeaker (when the loudspeaker is pressed downward, the force of the electric telescopic rod at the bottom of the loudspeaker is transmitted to the pressure sensor, the pressure signal is transmitted to the micro-control switch by the pressure sensor, and finally the micro-control switch controls the driving motor to drive the electric telescopic rod to extend upward, and after the top of the loudspeaker is released, the micro-control switch controls the driving motor to drive the electric telescopic rod to shrink downward) to avoid the loudspeaker from moving and pinching the human body; but this anti-pinch detection device needs the user to apply a certain force to the loudspeaker to start, and there is still a safety hazard in the use process, therefore we propose a vehicle-mounted loudspeaker human body anti-pinch device.
