DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a piezoelectric
transducer that is simple in construction and easy to assemble. In the conventional converter of
this type, as shown in FIG. 1, the conduction from the 1- (l- / Linno piezoelectric element 2 side is
performed by soldering such as a lead a6. However, since the electrode on the surface of the
piezoelectric element is generally very thin, the soldering is +15 and uneasy in terms of strength,
which makes it difficult to handle during assembly. Furthermore, there is a disadvantage that it is
necessary to connect the external terminal 6 by soldering etc. through the relay terminal 4 and
the lead and the weir 5 and the structure is complicated and it takes time to assemble. In
addition, since the spacer 8, the spacer pressing 9, the spacer 10, etc. are used to form the
braking slit 7, the number of parts is large, and the structure for adding one m1 is also
complicated. In order to eliminate the defects as described above, the conductive rubber rod and
the like are conducted from the piezoelectric element 1 through the elastic member, and the
parts are integrated by integrating the frame and the braking member. The purpose is to reduce
the size by 1-4 and simplify the process and make the assembly easy. This will be described in
detail according to FIG. Fig. 2 shows 1 ? 7) 1! ! Fig. 42 is a vertical cross-sectional view of V0,
and an exploded perspective view thereof. 1 is a metal plate, 2 is a piezoelectric cable, 11 is a
terminal plate made of a conductive material (11, 12 are conductive elastic members such as
conductive rubber, 16 is a terminal plate made of conductive material (2+, 14 is plastic etc.
Frame made of insulator, 15 is a protective case. One of the air leaks of the sound-to-air
converter composed of the metal plate 1 and the piezoelectric element 2 is fixed to the metal
plate 1 by pressure, and the terminal plate (1) 14 having continuity is taken out through the
frame 14 One of the air terminals is taken out from the pole face of the piezoelectric element 2
through the frame 14 via the conductive-elastic member 12 such as conductive rubber, and the
terminal plate +2113 bent in a tip-like shape. . By adopting such a configuration, it is possible to
stop the conventional soldering 7 times and simplify the construction 4 times, and it is also
possible to set up one direction by piling up of parts and the number of T-senior construction
works is also reduced. FIG. 6 is a longitudinal sectional view of an embodiment of the present
invention when the acoustic system has two degrees of freedom, and FIG. 5 is a perspective view
of Fs thereof. 16 is a first back air chamber composed of a flameproof plate consisting of a metal
plate 1 and a piezoelectric cable 2 and a frame 20, and 3-re 17 is a second back air chamber
composed of a frame 20 and a bottom plate 18 The number of parts can be reduced by utilizing
the plurality of holes 19 provided in the frame 2D as the auxiliary movement elements.
21 is a mesh damper such as a rope which is used for one history as needed for braking, and it
goes without saying that it may not be used depending on the necessary characteristics. As
described above, V (in accordance with the present invention, if the soldering of the piezoelectric
element is eliminated and the lead wire is removed, the terminal structure is simplified and the
one-way assembly is made ijJ, and the sound system is free By setting multiple fA holes in the
frame when making a decision, it is effective to reduce the cost and reduce the cost of a fourstory plant that saves parts for braking. 11A is a longitudinal cross-sectional view of the prior art
