DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sound generator
of an electronic buzzer. Conventionally, a piezoelectric element is attached to a metal plate, and
there is no integration. In the sound-production body, the metal plate and the piezoelectric
element are bonded and then painting is performed, or a rustproofing treatment such as plating
is performed beforehand on a base metal plate. -> After nine, the number of processes was large,
such as attaching a piezoelectric element. The present invention solves the above-mentioned
drawbacks, and it is an object of the present invention to provide a sound-producing body in
which bonding and coating of a metal plate and a piezoelectric element are performed in a simple
process. Next, an embodiment of the present invention will be described with reference to the
drawings. The drawings are sectional views of the present invention. 1 is a piezoelectric element,
2 is a metal plate, 5 is a support member at the periphery of the metal plate 2, and 4 is an
adhesive. Bonding the piezoelectric element 1 and the metal plate 2 by coating the piezoelectric
element 1 on one surface of the metal plate 2 and applying the adhesive 4 to the entire surface
of the superposed metal plate 2 and the piezoelectric element At the same time. Although not
shown in the south turn, the adhesive 4 penetrates into the joint between the piezoelectric
element 1 and the metal plate 2 so that the piezoelectric element and the metal plate are
integrally bonded. As described above, according to the present invention, bonding of the soundproducing body can be performed and painting can be performed in a simple process, and a
place that contributes to the improvement of productivity and the reduction of the price is thick.
