DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic
apparatus for bonding an electrostrictive transducer to a diaphragm or a solid body to emit or
detect ultrasonic waves. In this eyebrow ultrasonic device, there is 1N8 in which one side of the
electrodes provided on the vibrator is bonded to a diaphragm or a solid with an adhesive or the
like. In order to connect with the circuit, the device as shown in FIG. 2 and FIG. In FIG. 1, 1 is a
vibrator, 2 is a diaphragm or solid, 3 is a W pole on the non-adhesion surface side of the vibrator
l, 4 is a lead wire attached to the electrode 3, 5 is an adhesion surface of the vibrator 1 A part of
the electrode 1 covers the side face of the vibrator 1 and a part q of the non-adhesive surface.
The figure shows the wisdom of an adhesive that adheres to a 6-piece W ? 5 and adheres a
wedge lead-out wire, a 7-fold electrode 5 and a diaphragm or a solid 2. The ultrasonic device
shown in FIG. 2 has substantially the same configuration as that shown in FIG. 1 except that the
electrode 5 reaches the side surface of the imaging lever l. As described above, in the
conventional ultrasonic device, a part of WW on the adhesive surface side of the transducer is
extended to the side surface or the non-adhesive surface side of the imaging actuator, and the
lead wire is attached to the part. Therefore, the electrode on the non-adhesive side can not be
provided over the entire surface of the vibrator, in other words, since the polarization ineffective
portion exists in the perturbation, the efficiency of the vibrator is deteriorated. The ultrasonic
device according to the present invention is made to eliminate the above-mentioned conventional
drawbacks, and electrodes are provided on the entire surface of the city strain type resonator,
respectively, while lead wires are attached to the electrodes of il, The conductor is adhered to the
diaphragm or solid in contact with the conductor, and the conductor portion protruding from the
electrostrictive vibrator is used as a lead wire or a lead wire is attached to the conductor portion.
As a result, the polarization ineffective portion is eliminated and the efficiency of the vibrator is
better than that of the prior art. Hereinafter, an embodiment shown in the drawings will be
described. In FIG. 3, W poles 12.13 are provided on both sides of the electrostrictive vibrator 11
so as to be uniform. Attach the lead wire 14 to the negative electrode 12. The other wedging I3 is
adhered to the support 16 while the metal foil 15 is in contact with a part thereof. Reference
numeral 17 denotes an adhesive spring, and in fact, a thickness as thin as that of the metal foil
15 is preferable, and the lead wire 18 is attached to the portion of the metal foil 15 protruding
from the b0 vibrator 11. In place of the metal foil 15, the wedge 13 may be adhered to the
diaphragm 16 in a state where the lead wire 18 is in direct contact with the V pole 13. It goes
without saying that the object to which the vibrator 11 is attached is not limited to the
diaphragm lO.
As apparent from the above-described embodiment, the ultrasonic device according to (3) of the
present invention has the vibrator electrode between the vibrator electrode bonded to the
diaphragm and the solid and the vibrator electrode or the solid. The conductor is attached to the
diaphragm or solid by interposing a conductor of about the thickness of the adhesive layer so as
to contact with the conductor, and the grooved rod portion protruding from the vibrator is drawn
out. Since the lead wire is attached to the conductor, the electrode can be provided on the entire
surface of both surfaces of the perturbator, and the efficiency of the vibrator is improved.
