Abstract

The invention discloses a vibration sensor and audio equipment. The vibration sensor includes a housing, a microphone assembly, a vibration assembly and a pressure regulating plate. The microphone assembly cooperates with the housing to form a storage space; the vibration assembly is arranged on the In the storage space, the vibration assembly includes a first diaphragm fixed on the casing and a mass block attached to the first diaphragm, and the first diaphragm divides the storage space into a second A cavity and a second cavity, the mass block is provided with a mass block pressure equalization hole communicating with the first cavity and the second cavity; the pressure regulating plate is arranged at the mass block pressure equalization hole , and is used to follow the air flow between the first cavity and the second cavity to adjust the opening diameter of the pressure equalization hole of the mass block. The technical scheme of the invention is sensitive to low-frequency vibrations, and the vibrating membrane is not easy to break when heat is increased sharply or impacted.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a vibration sensor and audio equipment using the vibration sensor. Background technique [0002] At present, the existing vibration sensor includes a vibration sensing device and a vibration detection device that converts vibration into an electrical signal. The vibration sensing device has a diaphragm that induces vibration. The diaphragm resonates after receiving external vibration, thereby generating a resonant air wave. The vibration detection device converts and outputs vibration signals by detecting resonant air waves, and realizes the function of vibration sensing. In order to facilitate the vibration of the diaphragm, a mass block is usually arranged on the surface of the diaphragm, and pressure equalization holes are opened on the mass block to facilitate air pressure balance. When the opening of the pressure equalizing hole is large, the response of the vibration detec...
