PIEZOELECTRIC THROAT MICROPHONE

PROBLEM TO BE SOLVED: To solve the problem that the conventional throat microphone is not usable in noisy conditions since outside noise easily enters therein, is highly likely to cause howling, and does not allow achievement of reduction in thickness, size and weight.

Summary:PROBLEM TO BE SOLVED: To solve the problem that the conventional throat microphone is not usable in noisy conditions since outside noise easily enters therein, is highly likely to cause howling, and does not allow achievement of reduction in thickness, size and weight. SOLUTION: A piezoelectric throat microphone is a completely novel type of piezoelectric throat microphone that generates a sufficient sound range with clear sound pressure, especially, from a low-frequency range to a high-frequency range. The piezoelectric throat microphone allows selective use of a driver that meets the use purpose. Technically, the piezoelectric throat microphone is an excellent piezoelectric throat microphone which adopts bimorph specifications that are not used up until the present, use of trapezoidal ceramics, and new specifications or the like of an electrode plate.
