DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel ultrasonic
transducer such as a ceramic microphone. The implanting ultrasonic vibrator applies an electrical
signal to both terminals to vibrate the piezoelectric element and the resonator. Thus, the 1jL
movement of the piezoelectric element and the resonator continues even if the electric signal
applied to both terminals is removed. This is called reverberation and there are many causes. The
present invention has been made in view of the above points, that is, the lead wire connecting
both terminals and the piezoelectric element is provided with a 7φ-h twin screw, which causes
the reverberation due to the vibration of the lead wire. The purpose is to remove the The
following description will be made based on the drawings in which the present invention is given
as one embodiment. X is a vibrator main body, which is composed of a piezoelectric element 1
and a resonator 2. 3 is what the input terminal 4 is based on. Reference numeral 5 denotes a lead
wire connecting the input terminal 4 and the piezoelectric element 1 and attached with a weight
6. The weight 6 adheres an adhesive, for example. In the present invention, since the weight 6 is
attached to the lead wire 5 connecting the terminal 4 and the piezoelectric element 1 as
described above, the reverberation due to the vibration cause of the lead wire 5 is reduced and
thus the sensitivity of the vibrator is not reduced There is an effect that can reduce the
reverberation.
