BONE CONDUCTION SPEAKER APPARATUS HAVING PREVENTING STRUCTURE A VIBRATION

摘要

A bone conduction speaker having an anti-vibration structure is provided to maximize efficiency of vibrating sound by outputting forwardly the vibrating sound generated therefrom by applying a vibration-proof structure. A housing is positioned in an inside of an external housing of a bone conduction speaker. A magnet and a voice coil are installed in the inside of the housing in order to be coupled with a yoke(100). A vibration plate(20) is installed at the outside of the yoke. One or two or more ribs are formed by extending an outer circumference of the vibration plate to the outside. A coupling part is positioned at an end of the rib in order to be fixed to a casing(30). The coupling part having a coupling hole is formed at an end of the rib. The rib is coupled with the casing by using a coupling unit such as a screw or a rivet. A neck having a narrow width is formed among the coupling part, the vibration plate, and the housing.
