DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement
of a piezoelectric sounding system for generating an acoustic wave by grasping a body bonded to
a body 11ri piezoelectric element and a metal I by an electric circuit. The # 41sl + is a crosssectional view of a conventional piezoelectric sounding reconnaissance unit, in which a lead

vessel tslK 11111! Then, the complex is moved by 1 纏 (as K + * I l like-+ a + to generate a sound
wave in the direction of the arrow (-in the direction of-arrow) around one shield and one
vibration frequency of the complex. In addition, one combination is supported by bonding in the
above-mentioned の -vibration node @ ti 1116 ′ lK and case + 111 VC in a point-like or bell-like
manner (1) In such a 1241 鋤 S bowl, one bowl vibrates. Nodal part: 1A has a width 411 which is
less than gold <[1] and has a very small amplitude S as compared with the other C1 portion.
Therefore, it is a non-committee that raises the electrical bond sheet 7 by suppressing vibrations
from supporting the chained steel as in the case of persuasion, and also suppressing vibration
from the treatment. In addition, in the narrow area of about 11 IJ 1 in the section of the node, the
adhesion is difficult, and the indisonian may grow larger. In addition, because it is not E%

is a cross-sectional view of the amount of silver applied by applying the proposal *, which differs
from 4 in Figure 1 in that the sound wave generation port is opened and the composite ommxv
outer sheath is covered with polyethylene etc. A1 material (covered and supported by te J).
Because of this structure, the cost of the foam material is low and the suppression of the riot is
low, and the resonance impedance ta is 50 嘔 lower than the average at the average value as
shown in No. 31 S? Because the piezoelectric element, 11 and reef 111 [1 ffil and the
constriction S are isolated from the outside because of complete and complete sealing, the
danger of sodium hydroxide due to water droplets etc. is all. The cost of the sample measured at t
and i3 o'clock was tested. Piezoelectric element 55φxO, 5z% peristalsis 1 [50φX (T, 5tfl ones
