Abstract

319,118. Midhat, C. Aug. 20, 1928. Loud-speakers; diaphragms.-A loud-speaker comprises a resonance body 11, Fig. 2, and a plurality of strings 5, Fig. 1, stretched ever it, and connected to a freely suspended disc 1, driven by a driving unit 2, through a rod 10. A diaphragm 3 of known construction may be attached to the disc 1, and for speech reproduction a damper 4 may be lowered on to the strings. The resonance box itself may serve as a diaphragm, in which case a bridge member 8, Fig. 3, is clamped between the disc 1 and the front wall 7 of the resonance body 11, by nuts 9. The strings may be arranged inside the body 11, if desired.
