IPC: H04R1/40
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To show strong directivity by automatically switching whether to output only the output signal of a first microphone or to output the difference signal between first and second microphones so as to prevent the increase of the sound gathering quantity of surrounding random noise to reduce the output of sound generated from the direction except for that of a speaking person.
