The pressure sensing component and the flexible plate are assembled and moveable together. In the sensor of the present invention, after an external signal to be sensed is transmitted to the sensor, the flexible plate moves to induce air disturbances, and then the pressure sensing component receives a pressure change induced by the air disturbances and performs signal sensing. 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. ## Claims ### Claim 1 A sensor, wherein the sensor comprises a housing having an accommodating room, a flexible plate that is accommodated in the accommodating room and is moveable to induce a medium pressure change in the accommodating room, and a pressure sensing component configured for sensing the medium pressure change, wherein the pressure sensing component and the flexible plate are assembled together and can move together;
