Abstract

The electrodynamic loudspeaker has a cone shaped plastic support with a cone shaped diaphragm. The central section contains a loudspeaker coil which is mounted in the active air gap of a magnetic system. The outer edge of the coil is supported by the plastic cone support. The power handling capacity is 10 Watt. the diaphragm consists of a double layer. The first layer (1) reproduces the low tones and the second layer (2) produces the hgih tones. Both the diaphragms are connected at the centre and to the coil former (3) with centering ring (4). The magnetic system is connected to the cone support via a plate shaped metallic spacer. There is a terminal tag on the spacer for the electrical supply leads to the load speaker coil.
