Abstract

990,267. Stereophonic pick-ups. O. STEIDINGER, and S. STEIDINGER, [trading as STEIDINGER KOMM. - GES. GEB.]. July 12, 1962, No. 26785/62. Heading H4J. A sterophonic pick-up comprises a stylus 18, a stylus mounting 16 permitting movement in two orthogonal directions, a web 13 of resilient material mounted on the stylus mounting 16, two rigid links 11, 12 connected to the web 13 and located at right angles to one another, and two electro-acoustic transducers 1, 2, each acted upon by one link 11, 12 via a resilient coupling member 7. Coupling member 7 and web 13 are preferably of rubber and links 11, 12 are of aluminium alloy. The ends 14, 15 of the links 11, 12 are of angled cross-section. Each limb 9, 10, 14, 15 increases in crosssectional area away from the main link portion to ensure permanent seating in member 7 or 13. The transducers are piezoelectric " twisters " or are of electromagnetic type.
