IPC: H03L1/00
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain the circuit, preventing frequency fluctuation due to load fluctuation of a conventional PLL frequency synthesizer circuit adopting a conventional technology. SOLUTION: A switch SW 2 is provided between a PLL synthesizer 1 and an LPF 3, the switch SW 2 is open before an on/off timing of a power supply of an amplifier or a mixture being a load circuit, so as to disconnect an output of a phase comparator of the PLL synthesizer IC from the LPF, thereby keeping a frequency of a VCO 4 constant.

Title: Piezoelectric type electroacoustic transducer
Inventor: YAMAMOTO KAZURO
IPC: H04R17/10
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to lower the resonance frequency without varying the diameter and thickness of a piezoelectric diaphragm and requiring any special case material by providing a stress transmission suppressing means at the peripheral part of the piezoelectric diaphragm formed by sticking a piezoelectric element on one surface of a metallic plate. SOLUTION: The piezoelectric diaphragm 4 is constituted by sticking piezoelectric ceramics and an electrode 6a on the surface of the metallic plate 5 in order. The piezoelectric diaphragm 4 is fixed to a case with projections 5a which are decentralized and formed at the outer peripheral edge of the metallic plate 5 and spaces are formed between the projections 5. The spaces between the projections 5a operate as the stress transmission suppressing means and cut off the circumference-directional propagation of stress generated in the piezoelectric diaphragm 4 when the piezoelectric ceramics 6 are driven, thereby lowering the resonance frequency. In this case, the resonance frequency can effectively be lowered by properly adjusting the number, width W, and height H of the projections 5a. Consequently, the resonance frequency can be made low without varying the diameter D and thickness of the piezoelectric diaphragm 4 and requiring any special case material.
