Research Abstract	We conducted vibration apparatus composed of small device of electric coil and magnet, and examined frequency characteristics and input-output function resulted froma variety of waveforms and frequencies applied (pure tones, tone burst, and FM waves). The abovementioned new apparatus will be expected to improve the fitness and usefulness due to good passage of external ear canal.
