Abstract[English]
The present utility model provides a bone conduction microphone, comprising a base provided with a cavity having openings at both ends, a back plate provided above the base, and a vibration structure provided between the back plate and the base. The vibration structure comprises a diaphragm provided between the back plate and the base and spaced apart from the back plate and the base, and a mass block suspended below the diaphragm and inserted into the cavity from the opening at one end of the cavity. The bone conduction microphone further comprises a limiter configured to limit the maximum displacement of the vibration structure. The bone conduction microphone of the present utility model has high reliability.[French]
Le présent modèle d'utilité concerne un microphone à conduction osseuse, comprenant une base pourvue d'une cavité ayant des ouvertures aux deux extrémités, une plaque arrière disposée au-dessus de la base, et une structure de vibration disposée entre la plaque arrière et la base. La structure de vibration comprend une membrane disposée entre la plaque arrière et la base et espacée de la plaque arrière et de la base, et un bloc de masse suspendu sous la membrane et inséré dans la cavité à partir de l'ouverture à une extrémité de la cavité. Le microphone à conduction osseuse comprend en outre un limiteur conçu pour limiter le déplacement maximal de la structure de vibration. Le microphone à conduction osseuse du présent modèle d'utilité présente une fiabilité élevée.[Chinese]
