Abstract
318,380. Aspden, R. L. Aug. 25, 1928. Phonographic recorders and reproducers; magnetic instruments.-In a combined gramophone sound box and pick-up or recorder, the stylus bar carries a coil which oscillates in a magnetic field. The stylus bar b, Fig. 1, has a ring k attached, supporting a coil l in air gaps of a pot magnet m, the leads from the coil to the amplifier being taken from terminals g, f. The ring k may be secured directly on the diaphragm d. The stylus bar b, Fig. 2, has a winding o, connected to terminals g, f, which oscillates in the field of the magnet p, secured to the rim of the sound box a. Acoustic recording may be made simultaneously with electric recording.
