Abstract
A vibration sensor includes a vibration receiver and an acoustic transducer. The vibration receiver includes a housing and a vibration unit. The housing forms an acoustic cavity. The vibration unit is located in the acoustic cavity and divides the acoustic cavity into a first acoustic cavity and a second acoustic cavity. The acoustic transducer is acoustically connected to the first acoustic cavity. The housing is configured to generate vibration based on an external vibration signal. The vibration unit vibrates in response to the vibration of the housing and transmits, through the first acoustic cavity, the vibration to the acoustic transducer to generate an electrical signal. The vibrating unit includes a mass element and an elastic element. A deviation between cross-sectional areas of the mass element and the first acoustic cavity perpendicular to a vibration direction of the mass unit is less than 25%.
