Abstract

856,829. Binaural pick-ups. BAYLIFF, R. W. Sept. 18, 1958 [Oct. 8, 1957], No. 31481/57. Class 40 (4). A binaural pick-up has an armature 10 mounted so that it can move vertically or laterally, as viewed in Fig. 1, so as to influence the flux through coils 29 and 17, respectively. The armature is carried by a leaf-spring 11 and a wire (not shown) in the manner described in Specification 748,982. Lateral movement of the armature affects the flux between the polepieces 18 of a magnet 33 so inducing a current in a pancake-shaped coil 17. Vertical movement affects the gap 31 of a second magnetic system so inducing a current in coils 29. The magnetic systems are adjustable (Figs. 3 and 5, not shown) with respect to the armature. For use with combined lateral and hill-and-dale records the coils 17 and 29 feed the appropriate channels separately. For use with records in which the two channels are recorded at angles of 45 degrees to the vertical the outputs of the coils are added and subtracted to reproduce the signals. In this case the coils 29 may be duplicated and the circuit is then as shown in Fig. 7.
