<P>PROBLEM TO BE SOLVED: To provide a three-dimensional sound transceiver for localization of sound images including depth feeling or depth perception by movement of a sound source. <P>SOLUTION: A three-dimensional sound transceiver comprises a transmitter and a receiver. The transmitter has: a modulation section for multiplexing and modulating a signal input from a sound field microphone section composed of a plurality of right and left microphones; and a signal transmission section for transmitting the signal modulated by the modulation section. The receiver has: a demodulation section for demodulating the modulated signal; a calculation section for calculating a moving direction of a sound source from differences of sound pressure in arbitrary time change; a distance measurement section for measuring a distance from a listener; a speaker section composed of a plurality of speakers; and a sound wave deflection section for making sound output from the speaker section reflect, by being controlled based on the calculation result by the distance measurement section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
