Abstract:
1. A portable telephone comprising: a bone conduction device having an outer surface edge; a housing having a concave portion with a bottom portion and an inner edge surface, said concave portion of said housing being larger in diameter than said bone conduction device when said bone conduction device is operatively positioned therein; a cushioning material operatively disposed between said inner edge surface of said concave portion of said housing and said outer surface edge of said bone conduction device such that said bone conductive device is supported in the concave portion of the housing only by the cushioning material disposed around the bone conduction device; a gap formed between said bone conduction device and said bottom portion of said concave portion of said housing such that no cushioning material is disposed in said gap, thereby reducing the thickness of the portable telephone; and a vibration surface of said bone conduction device positioned to be slightly extended outward from said housing by said cushioning material.
