Abstract
The present disclosure provides a vibration sensor. The vibration sensor may include a vibration receiver and an acoustic transducer. The vibration receiver may include a housing, a limiter and a vibration unit. The housing and the acoustic transducer may form an acoustic cavity. The vibration unit may be located in the acoustic cavity to separate the acoustic cavity into a first acoustic cavity and a second acoustic cavity. The acoustic transducer may be acoustically connected to the first acoustic cavity. The housing may be configured to generate a vibration based on an external vibration signal. The vibration unit may change an acoustic pressure within the first acoustic cavity in response to the vibration of the housing, such that the acoustic transducer generates an electrical signal. The vibration unit may include a mass element and an elastic element. A first side of the elastic element may be connected around a side wall of the mass element. A second side of the elastic element may be connected with the limiter.
