き受話器。 A thin ceramic plate with a safe electrode is pasted on one or both sides of a thin metal plate, and a diaphragm 2 that vibrates and generates a sound wave corresponding to the signal voltage by applying a signal voltage to the electrode is attached to the frame 1. A groove 1a is provided on the side surface of the frame 1, and a coil 10 for passing a signal current is wound therein.A printed circuit board 8 is attached to the back of the frame 1, and a back case 4 is attached. A passage is formed between the back case 4 and the second volume 13b between the diaphragm 2 and the frame 1 and the third volume 13c between the frame 1 and the back case 4 through acoustic resistance. The electrode printed circuit board 8 of the diaphragm 2 has one end electrically connected to the terminal piece 6 and the other end electrically connected to the terminal 9 protruding outside the back case.
