Abstract

1,224,199. Reverberation devices. AKUSTISCHE U KINO-GERATE G.m.b.H. 27 Nov., 1968 [29 Nov., 1967], No. 56218/68. Heading H4R. An artificial reverberation device includes an helical spring which has straight portions axially extended in the. direction of spring tension joined by a curved portion where the turns are sufficiently spaced to prevent contact between adjacent turns. Since the spring is required to carry out torsional vibration it must be mounted at points on its axis and a spring turn near the end of straight portions 1, 3 is deformed and attached to supports 9, 10 through a suspension wire or small spring. The free ends of the spring are attached to input and output transducers 7, 11. To accommodate very long springs further bends, not confined to a single plane, may be provided.
