Abstract

282,383. K³chenmeister, H. J. Dec. 15, 1926, [Convention date]. Magnetic instruments. - A sound recording device is actuated by two or more actuating means influenced by separate sound receivers, and the means are made adjustable and interchangeable and the impulses supplied thereto may be amplified so as to vary the effect of each means to overcome resonance and enhance the values of anv desired receiver or receivers. Provision is also made for adjustably damping the recording device. The invention is applicable for recording by a stylus, to photographic recording, or to magnetic recording on a strip or wire. Fig. 1 shows a recording stylus a secured to a centrally pivoted aluminium disc b carrying sets of armatures d', d<2>, d<3>, influenced by adjustable and interchangeable electromagnets e<1>, e<2>, e<3> connected with separate sound receivers, through terminals f<1>, f<2>, f<3> and amplifiers if desired. Damping of the disc is effected by electromagnets g<1>, g supplied with current which may be adjusted. Resilient means are provided for centralizing the disc.
