Abstract: A sensor includes a housing having a accommodating room, a flexible plate provided in the accommodating room and moveable to induce a medium pressure change in the accommodating room, and a pressure sensing component for sensing the pressure change. The pressure sensing component and the flexible plate are assembled and moveable together.

Compared with the conventional sound sensor, the sensor of the present invention provides no opening communicating with the external environment. Therefore, the impact of foreign objects, noise and other environmental factors on the sensor can be avoided, and the signal generated by the object not to be sensed can be effectively reduced.
