Cartilage conduction hearing device using an electromagnetic vibration unit, and electromagnetic vibration unit
First Claim
1. A hearing device, comprising:
- an electromagnetic vibrating element including two parts that move relative to each other; and
an elastic body, whereinone of the two parts includes a voice coil bobbin around which a voice coil is wound,the other of the two parts includes;
a yoke holding a magnet and a central magnetic pole, anda top plate anchored to the magnet and the central magnetic pole,the voice coil penetrates into a gap in the top plate without making contact with the top plate,the other of the two parts is movable relative to the one of the two parts,the elastic body is in contact with at least one of the voice coil bobbin and the yoke, andvibration for cartilage conduction is extracted from at least one of the two parts.

Abstract
Provided is a portable telephone or an earphone or an electromagnetic-type vibration unit that comprises an electromagnetic-type vibrator including two mutually relatively moving portions supported via an elastic body, and that is configured to produce vibrations from at least one of the two portions for cartilage conduction. The elastic body provides a cartilage conduction portion to be contacted with the ear cartilage. The elastic body is disposed on or in the vicinity of an upper corner portion of a housing. One of the two portions is supported on a housing structure with the elastic body supported by the housing structure, and the other of the two portions is supported by the elastic body. Of the two portions, one with a greater weight is supported by the elastic body.
