The present invention relates to a vibrating earphone unit for transmitting a vibrating sound to a user from a source which generates both vibrations and sound, the vibrating earphone unit comprising: an upper housing; a lower housing; a vibrator; an elastic part, which is composed of a flat spring whose inside is connected between a yoke and a rivet of the vibrator and an insert gasket coupled to the outer peripheral surface of the flat spring such that the upper and lower sides thereof are fixed and coupled by the lower side of the upper housing and the bottom surface of the lower housing; a sound source transmission part, which is composed of a sound source transmission plate in the form of a thin plate coupled to an open surface of the upper side of the upper housing and a high-pitched sound offset plate for offsetting a high-pitched sound towards the upper side of the sound source transmission plate; and a voice coil on the lower side of the sound source transmission plate of the sound source transmission part. Because the sound source transmission plate of the sound source transmission block, which is an aluminum thin plate, generates vibrations by receiving, at a minute level, a sympathetic vibration that is produced and gathered in the housing when the vibrator causes vibrations by an applied current from the coil, the vibration earphone of the present invention can increase the efficiency of vibration through such a dual vibration effect. |
