Patent ID: 11601538

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. Of the two portions, one or a portion connected thereto provides a cartilage conduction portion to be contacted with the ear cartilage, with the elastic body disposed between the two portions. From both of the two portions, vibrations to be conducted to the elastic body are obtained.
