PROBLEM TO BE SOLVED: To provide a silicon chip for an earphone with a holder for transmitting a powerful sound to an eardrum by applying appropriate pressure without protruding from an ear hole.SOLUTION: By making a chip 1 and a holder 2 to be an integral structure, the chip 1 is not protruded from an ear hole and appropriate pressure can be applied, so that a powerful sound source of the earphone whose medium-to-high sound range does not become unclear is transmitted to an eardrum.SELECTED DRAWING: Figure 1 |
