Abstract

626,086. Stereophonic microphones. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 21, 1946, No. 34545. Convention date, May 17, 1943. [Class 40 (iv)] To produce a stereophonic effect, an artificial head is made in two halves 1, 2, each with a microphone 3, 4, whereby the microphones can be adjusted to face in desired directions. To maintain the microphones in a horizontal plane the head is supported on a concave base 5.
