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. 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.

Abstract: A dual-axis acceleration detection element comprises a first detection element, a second detection element and a stationary unit. The first detection element is movable relative to the second detection element. The second detection element is movable relative to the stationary unit. The relative movements take place on different axes to detect acceleration on two different axes. The first detection element and the second detection element are interposed by corresponding detection electrodes, and the second detection element and the stationary unit also are interposed by other corresponding detection electrodes. Hence when the relative movements occur among the first and second detection elements and the stationary unit, overlapped areas of the detection electrodes change to generate and output a capacitance difference, thereby acceleration alteration can be detected.
