Title: Microphone
Inventor: NAONO HIROYUKI
IPC: H04R1/40
Filed: 1982-04-19
Abstract: PURPOSE:To attain the microphone used for loudspeaking in a room hardly causing howling and hardly collecting noise on a stage, by arranging plural microphone units on a primary dimension bow and in parallel with a horizontal plane by taking a point as a center, and picking up outputs with summation. CONSTITUTION:MiC0-MiCN are arranged in a circular arc by taking a focus F as a center with a distance Lo and outputs are picked u with summation. The unidirectional microphones are directed to th focus F and fitted horizontally to a stage 1. In Figure, RS is a sound source and IMS is its image. When the sound source is placed at the focus F, the synthesized output is (2N+1)-times the output of one microphone. When the sound source is placed other than the focus F, a phase difference is caused, the synthesized output is decreased and only the sound at the focus F only is collected efficiently. The sound other than the focus F is cancelled with each other because of the phase difference, and even if there is a noise source between the focus F and the microphone, the sound of the focus only is collected in the good way. In constituting the microphones horizontally to the stage 1, even if the sound source is moved up and down at the focus F, the distance Lo between each microphone and the sound source is constant and the moved sound source is collected efficiently.
