MICROPHONE WHICH INCREASES TREBLE RANGE AND SOUND PRESSURE BY CONNECTING ELEMENT OF PIEZOELECTRIC CERAMICS OR UNIT OF CARTRIDGE TO UNIT OF ELECTRET CAPACITOR MICROPHONE OR DYNAMIC MICROPHONE WHILE ADDING CAPACITOR AND RESISTOR AND ALSO SERVES AS PHANTOM POWER SOURCE

摘要

PROBLEM TO BE SOLVED: To provide a self power generation type microphone without requiring the use of a phantom power source when using an electret capacitor microphone for dynamic microphone correspondent equipment while correcting a sealed vibrating microphone such as an earhole microphone or a throat microphone liable to have lower sounds or stuffy sounds into treble range and high sound pressure. ;SOLUTION: Concerning a self power generation type microphone having an effect for increasing a sound pressure of the microphone by radiating a treble range with piezoelectric ceramic to compensate for lower sounds or stuffy sounds in the case of picking up the sounds of a unit of electret capacitor microphone E or dynamic microphone L for sealed vibrating microphone while using it as a phantom power source by adding a capacitor or resistor on the basis of characteristics that a voltage is generated when an element or a cartridge of piezoelectric ceramics is vibrated, this microphone can be also used for equipment using the capacitor microphone or dynamic microphone as it is without the phantom power source.;COPYRIGHT: (C)1999,JPO
