Abstract

791,901. Loud-speakers. WHITELEY, A. H. Aug. 25, 1955 [Aug. 27, 1954], No. 24947/54. Class 40 (4). A loud-speaker has an air gap in which is disposed a moving coil in at least two parts adapted to have separate electrical connections made to them, so that different impedances can be obtained by connecting them in series or in parallel. Specification 787,424 is referred to.
