BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross sectional view of a conventional
piezoelectric monomorph electroacoustic transducer, and FIG. 2 is a cross sectional view showing
one embodiment of the piezoelectric monomorph electroacoustic transducer according to the
present invention.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement
in the structure of an electro-acoustic transducer for generating an audible sound by bending and
vibrating a monomorph vibrator in which a piezoelectric element and a diaphragm are joined and
integrated. The aim is to enable large amplitude excitation efficiently and without damaging the
piezoelectric element in order to emit a loud alarm line. Mon-Electronic Memo (1)-"I" is a 7-to-1
electrical 8-to-sound conversion group or, for example, for automatic heavy-duty use in
conjunction with the Ho 7 1 "jt! One side is 115 dh (· ! A conventional piezoelectric
monomorph electroacoustic transducer, generally referred to as a piezoelectric stressor, where a
sound pressure of − is necessary, as shown in FIG. The maximum sound pressure of the
piezoelectric stressor is l771 ahead (· about 105 tlb, and a large input is put into question as a
problem in history, and the damage to the element is inevitable). I wanted. This invention is to
register utility model in order to achieve surface distortion purpose. 6) which constitutes the
electroacoustic transducer of the structure described in the scope of the invention, and in order
to make the present invention more clear, the specific embodiment shown in FIG. 1 (Majority of a
