Abstract
A Passive loudspeaker enclosure for a television receiver. Interference in the reproduced picture caused by magnetic stray fields from the enclosure occurs, in particular, with color television receivers with 33 inch picture tubes. The task is to reduce the magnetic stray fields by employing simple measures and without using additional components until the interference no longer appears in the picture. In particular, for a loudspeaker enclosure in a television receiver with a 33 inch picture tube.
Claims7
A passive multipath loudspeaker enclosure for a television receiver for minimizing magnetic interference in a proximal picture tube, comprising the combination of the following features:
- a) the only magnetic part within the enclosure is a loudspeaker magnet structure, which has a screen for magnetic stray fields, with other portions of a loudspeaker frame and a diaphragm being made from non-magnetic materials;
- b) a plurality of housing components, said components being made from non-magnetic material and fitted together without any metal parts using a plurality of interlocking clip connectors and an adhesive connection;
- and
- c) filters for dividing the frequency bands between a plurality of loudspeakers being realized by means of mechanical measures disposed at the loudspeakers.
