Abstract

980,067. Loud-speakers; reverberation devices. W. REHDE. May 21, 1962 [March 12, 1962], No. 19490/62. Headings H4J and H4R. A reverberatory loud-speaker device comprises at least one spring fixed at its ends on a support and connected at a point between its ends to a loud-speaker cone so that vibrations of the cone give rise to reverberatory vibrations in the spring or springs. A loud-speaker driving unit is secured in a bass reflex cabinet and has a cone to which is adhered a ring. Integral with the ring is a rod 7. Three helical springs are connected at their centres to the rod 7 and at their ends 4 1 , 4 2 , 5 1 , 5 2 , 6 1 , 6 2 to supports secured to the cabinet. In front of and spaced from the front wall of the cabinet is a cloth screen.
