Abstract

PURPOSE:To miniaturize an ultrasonic vibrator, by bringing an elastic material into contact with a surface desired to prevent vibration from the opposite side of an ultrasonic wave transmitting surface thereof to house the elastic material on the side where a piezo-electric is to be arranged. CONSTITUTION:In an ultrasonic vibrator in which a piezo-electric element 1 is junctioned on the inner surface of a diaphragm 2 having a closed construction, an elastic material 3 is brought into contact with a surface desired to prevent vibration from the opposite side of an ultrasonic wave transmitting surface and a terminal base 4 is provided to pressurize so that the elastic material 3 is pressed evenly on the contact surface. This can house the elastic material 3 on the side where the piezo-electric element is arranged, thereby enabling minimaturization of the device. This also makes the elastic material 3 press on the surfaces desired to prevent vibration, thereby enabling a reduction in the reverberation of the diaphragm 2 quantitatively and accurately.
