Abstract
A vibration sensor () is provided, comprising: a vibration receiver () including a housing () and a vibration unit (), the housing () forming an acoustic cavity, the vibration unit () being located in the acoustic cavity and separating the acoustic cavity into a first acoustic cavity () and a second acoustic cavity (); and an acoustic transducer () acoustically connected to the first acoustic cavity (). The housing () is configured to generate a vibration based on an external vibration signal, the vibration unit () changes an acoustic pressure within the first acoustic cavity () in response to the vibration of the housing (), causing the acoustic transducer () to generate an electrical signal. The vibration unit () includes a quality element () and an elastic element (), an area of the quality element () on a side away from the acoustic transducer () is smaller than an area of the quality element () on a side close to the acoustic transducer. The elastic element () is connected around a side wall of the quality element ().
