Hearing structure utilizing bone conduction and hearing device utilizing bone conduction provided with the structure

摘要

To provide a sound structure having bone conduction and bone conduction having the structure, which does not feel stress due to tightening, is lightweight, has excellent design, is easy to install and remove, is comfortably and stably mountable Provide a used hearing device.A bone conduction drive for converting an acoustic electric signal into vibration is housed in a housing, a vibration output structure for outputting vibration converted by the bone conduction drive, a bone conduction drive disposed above the casing A hook to be hooked on a recess in the vicinity of the bevelling protruded from the outer peripheral edge of the ear canal and a clip disposed openably and closably on the lower part of the housing, And the vibration output structure is brought into contact with the vicinity of the antitragal cartilage to enable sound recognition by bone conduction.BACKGROUND OF THE INVENTION
