Abstract
In a moving coil loudspeaker, a soft magnetic plate 13 and pot 12 are held rigidly together by one or more indentations 10 formed in a generally frusto-conical frame 16. Conical part (121), Fig. 2 (not shown), has an apical angle ([alpha]) a little smaller than the apical angle (#) of the frame part (161) to assist in providing a rigid assembly. In manufacture, the frame 16 is placed on a press and the pot 12 and plate 13 are then placed in position. Grooves or other indentations 10 are then made with four or six different balls. The loudspeaker includes a central magnet 13 which is secured by adhesive or a brass centring ring either before the formation of the indentations or subsequently. The frame 16 is of aluminium coated with plastics material or is of extruded plastics.
