Filed: 1984-09-03
Abstract: PURPOSE:To improve tone quality and to enlarge mechanical strength by fixing an outer circumference of a component element to a frame which forms a rib at the part protecting a component oscillating part. CONSTITUTION:Ribs 7a, 7b and 7c extending radially almost to the center part are formed at a metallic frame 4'. A method to fit a piezoelectric component element 3 to the frame 4' is the same as the conventional one. Because of such a composition, a resonance point of a frame 4 itself can be designed so as to stand high frequency, and for that reason, chatter and noise in an audible scope can be removed, sound pressure will not be decreased, a reproducing sound at the high sound area is also very clear and easy to hear and tone quality can be widely improved. Since mechanical strength can be sufficiently large, a damage of external appearance and an element due to external impacts such as dropping and collision can be prevented and by a thinner metallic frame than conventional, a piezoelectric sounding body with more increased strength can be supplied.
