Abstract

PURPOSE:To make it possible to wireless-receive signals transmitted from the acoustic unit main body, by providing a receiving antenna, a receiving part and a sounding part inside the earphone unit. CONSTITUTION:Ear contact part 12 is provided on the reverse face of the earphone, and this part is provided with through holes 13 which cause sound generated by the sounding part to pass through. Loop-form ear hook part 14 is provided coaxially in the earphone main body. Ear hook part 14 is formed with flexible resin and so on. The inside of earphone main body 11 and ear hook part 14 are provided with receiving antenna 21, a receiving part, a sounding part, and a power source. Receiving antenna 21 is stored in groove part 142 provided along the reverse face part of ear hook part 14 to form a loop-form antenna.
