Abstract

PURPOSE:To attach and detach not only easily but also prevent an electric discharge phenomenon, without giving a sense of incongruity to a user when it is installed, by providing a transformer and a capacitor in the head phone housing. CONSTITUTION:In the casing, the electric acoustic unit 16 is installed so as to be opposed to the sound emitting part 14. This unit 16 makes a fixed electrode 21 having plural through-holes 20 install to the stretched fixed ring 18 of the diaphragm 17 so as to be opposed. Also, a holding ring 22 consisting of a conductive material is made to contact against the reverse side of this electrode 21. Moreover, a capacitor 41 for preventing the electric discharge is connected between the rings 18, 22 in the casing 11. And, when the signal voltage is raised by the transformer 35 and it is applied to the rings 18, 22, the diaphragm 17 is vibrated. At this time, even if the intensity of electric field between the diaphragm 17 and the electrode 21 exceeds 10<6>V/m, generation of the electric discharge phenomenon is prevented by operation of the capacitor 41.
