金属And a pair of lead-out pins electrically connected to the double-sided electrodes of the
piezoelectric element on the bottom surface of the outer case O, and the outer surface of the
metal cylinder and the -port end edge And an ultrasonic microphone comprising a vibration
absorbing material loaded between them and the inner surface of the corresponding outer case.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic
microphone that emits ultrasonic waves in the air or receives reflected waves from an object, and
provides an objective microphone that can be fixedly attached to a holder. It is to be. In general,
in the ultrasonic microphone, an insulating cover plate is attached to the opening end face of a
bottomed cylindrical metal case having a piezoelectric element attached to the inner side of the
closing surface to make a sound wave transmitting / receiving surface. The lid plate is sealed, and
a pair of lead pins electrically connected to both electrodes of the piezoelectric element are
embedded in the lid plate, and the microphone main body is brazed to the holder by the lead
pins. There has been a drawback that the lead-out pin is easily bent due to dynamic vibration,
impact, etc., and the state of the sound wave transmission / reception surface changes to
deteriorate directivity. On the other hand, if the outer surface of the metal case is directly held, it
can be held firmly, but in this case, the outer surface of the metal case is also vibrated integrally
with the sound wave transmitting / receiving surface, which causes a problem in terms of
transmission / reception sensitivity.
The present invention has been made to solve such a drawback, and in the following description
of the embodiments of the drawings, I represents stainless steel etc. k) 7'1. A metal cylinder
molded into a bottomed cylindrical shape by thread processing, etc., a piezoelectric element
integrally bonded by an adhesive to the inside of the coughing metal cylinder so that the closing
1111111 / a of the coughing metal cylinder is to be the sound wave transmitting / receiving
surface The metal cylinder is used as its sound wave transmitting / receiving surface l! An
insulating outer case made of synthetic resin loosely fitted with L facing upward, and has 7
mounting flanges (") Ja on the outer surface. A pair of + a and dab are disposed on the bottom
surface of the extranuclear case 3 so that one end thereof projects into the case, and are
electrically connected to both sides of the piezoelectric element via electrodes a and b via
conductors ja * jb. A lead-out pin, 6 is a spacer interposed between the open end edge of the
metal cylinder 0 and the inner bottom surface of the outer case 3, 7 is a periphery p of the outer
surface of the metal cylinder and the inward facing of the outer case In the case of the adhesive,
the spacer and the adhesive 7 respectively vibrate the vibration from the metal cylinder 1? A
substance having a function of relaxing and absorbing so as not to be transmitted to, for
example, silicone foam rubber as the spacer t, and a silicone rubber adhesive as the adhesive 7

are selected and used. As described above, the present invention is configured such that the
outward direction of the metal-coated cylindrical body to which the f electric element is bonded
is fitted to the insulating outer case through the vibration absorbing material so that the
vibration from the metal cylindrical body is not transmitted to the outer case Since the outer
surface of the outer case can be firmly attached to the holder, there is a great advantage that the
sound wave transmitting / receiving surface of the microphone body can always be maintained in
a fixed state even if external impact or vibration is applied. is there.
