Abstract

659,066. Sound reproducing circuits. BOSWELL, I. I., and PLANER, F. E. Nov. 6, 1947, No. 29643. Drawings to Specification. [Class 40 (iv)] In a transducer arrangement in which two or more electro-acoustic transducers are employed concurrently and negative feed-back is provided around at least two of them, each transducer incorporating negative feed-back has a separate feed-back path. If the transducers each deal with a different frequency range the feed-back path of each is prevented from affecting other transducers.
