摘要： The present invention relates to a condenser microphone whose body can be miniaturized while keeping a property and a sound quality comparable to those of a conventional condenser microphone. The condenser microphone includes a cylindrical body, a plurality of vibration plates which are formed into the shapes of squares and placed in parallel to a body axis line within the body, acoustic holes formed on a body side wall in a direction vertical to the vibration plates and back pole plates which are placed on a side opposite to the acoustic holes with the vibration plate between and face on the respective vibration plates at an interval of a micro gap. A potential of the back pole plate is varied according to a vibration of the vibration plate.

摘要： In a microphone, unnecessary radiation can be easily reduced with a simple construction. This invention provides a power supply output generating means for generating a power supply output of predetermined voltage on the basis of an output of a power supply unit; a tone signal generating means for operating according to the output of the power supply unit and generating a tone signal; a sound electric signal converting means for converting a sound into an electric signal; a mixing means for mixing the sound signal obtained by the sound electric signal converting means and the tone signal; a modulating means for modulating a carrier wave with a low frequency signal consisting of the sound signal and tone signal which are mixed by the mixing means; and a transmitting means for transmitting modulated wave signal modulated by the modulating means in an electric wave, and wherein the tone signal generating means generates the tone signal having predetermined frequency and predetermined frequency deviation such as not to extend across predetermined frequency bandwidth of the carrier wave, and the voltage generating means generates the power supply output of predetermined voltage on the basis of the output of the power supply unit by using the tone signal as a clock.
