DESCRIPTION JPS5136673
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal sectional view of an
embodiment of the present invention. E resonance box, 4 ииииииии Support rod, 5 иииииииииииииииии ????
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic shoe
having a piezoelectric or mineral electromagnetic type sounding diaphragm. As a conventional
electronic buzzer, there is known an electronic buzzer having a sound generation diaphragm
which is magnetically excited in a piezoelectric sound generation diaphragm in which a metal
plate and a piezoelectric element are bonded). In order to obtain sound pressure, it is difficult to
obtain sufficient sound pressure with low power. (1) Smallness, -J ant, Si 'The present invention
eliminates the above-mentioned drawbacks, and by supporting a resonance box on a sound
generation diaphragm, an electron which can obtain an efficient sound pressure It is intended to
be able to provide a buzzer and to provide new resonance effect techniques. Next, an
embodiment of the present invention will be described with reference to the drawings. The
drawing is a longitudinal side view of the present invention. The sound generation diaphragm 1
is a piezoelectric sound generation diaphragm to which a piezoelectric element is attached, or a
sound generation diaphragm excited electromagnetically. A resonance box 5 is provided on the
upper surface of the sound generation diaphragm 1, and is supported by the resonance box 3
company support rods 4, and the support rods 4 are fixed to the sound generation diaphragm 1.
The number of the support rods 4 supporting the resonance box 5 may not be one, and may be
two or more. The sound is enhanced when the number of resonance fluid determined by the
shape of the resonance box 3 is equal to the vibration frequency of the one sound generation
diaphragm 1, and the sound is emitted from the relation between the outer circumference of the
resonance box S and the sound generation diaphragm 1 Be done. The present invention company
offers a low power electronic pump because it sells a large sound pressure by vibration of a
slight sound production *** due to a small sound generation ***. ?),: ,, lt) There is a sharp effect.
