Abstract
1,016,298. Stereophonic pick-ups. NIPPON COLUMBIA KABUSHIKI KAISHA. June 27, 1963 [Aug. 2, 1962; May 1, 1963], No. 25629/63. Heading H4J. A sterophonic pick-up comprises two conductors supported parallel to one another each in a magnetic field and joined by a stylus carrier. The two conductors R 1 , R 2 (Fig. 2), are metal ribbons or wires. They are disposed in air gaps g 1 , g 2 respectively of a magnetic circuit comprising a permanent magnet 1 and a member 2 of " soft " magnetic material. The conductors R 1 , R 2 are held under tension by supports S 1 , S 1 <SP>1</SP> and S 2 , S 2 <SP>1</SP> (Fig. 1, not shown), at their ends. The supports S 1 , S 1 <SP>1</SP> and S 2 , S 2 1 are connected to terminals t 1 , t 1 <SP>1</SP> and t 2 , t 2 <SP>1</SP> respectively. In use the output from terminals t 1 , t 1 <SP>1</SP> corresponds to modulations of one groove wall of a 45/45 type record while the output from terminals t 2 , t 2 1 corresponds to modulations of the other groove wall. In another arrangement (Figs. 4 to 8, not shown), two parallel coils L 1 , L 2 are wound on a common bobbin 11 secured in non-magnetic housing. The portions L 10 , L 20 of the coils L 1 , L 2 are adjacent a groove 13 in the bobbin 11 and vibrate in the air gap provided by a permanent magnet 1 and polepieces in response to movement of a stylus 3c.
