Abstract

686,934. Loud-speakers. PLESSEY CO., Ltd. Nov. 21, 1951 [Nov. 21, 1950], No. 28414/50. Class 40 (iv). To prevent the leads of a moving coil rattling against the diaphragm and to avoid the introduction of resonances in the diaphragm by the use of an adhesive, the leads pass through eyelets or holes 2 and 6 in the centring member before passing to the fixed terminals on the rigid chassis of the speaker.
