Title:
VIBRATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/142737
Kind Code:
A1
Abstract:
A vibration sensor (200). The vibration sensor comprises: a vibration receiver (210) comprising a housing (211) and a vibration unit (212), wherein the housing (211) defines an acoustic cavity, and the vibration unit (212) is located in the acoustic cavity to divide the acoustic cavity into a first acoustic cavity (213) and a second acoustic cavity (214); and an acoustic transducer (220) in communication with the first acoustic cavity (213), wherein the housing (211) is configured to generate vibrations on the basis of an external vibration signal, and the vibration unit (212) changes the acoustic pressure in the first acoustic cavity (213) in response to the vibrations of the housing (211), such that the acoustic transducer (220) generates an electrical signal; and the vibration unit (212) comprises a mass element (2121) and an elastic element (2122), the area of one side, away from the acoustic transducer (220), of the mass element (2121) is smaller than the area of one side, close to the acoustic transducer (220), of the mass element (2121), and the elastic element (2122) is connected to a side wall of the mass element (2121) in a surrounding manner.
