ABSTRACT:
A loudspeaker for generating sound from an electrical current provided by an external source may include an adapter and/or a guide for supporting, directing and routing lead wires carrying the electrical current from the external source. The lead wires may be routed through a guide supported by a pole assembly in the center of the loudspeaker in order to keep the mass associated with the lead wires as near as possible to a moving voice coil former. In this manner, detrimental effects of premature failures and undesirable noise caused by movement of loudspeaker components during operation may be significantly reduced. The guide may include apertures for supporting the lead wires at a desired angle and directing the lead wires toward the external source. Alternatively, or in combination with the aforementioned guide, the lead wires may be routed through an adapter attached to the voice coil former. The adapter may include apertures for positioning splices connecting flexible wires and voice coil lead wires which form the lead wires. A method of protecting the lead wires which carry the electric signal from the external source to the loudspeaker from damage due to movement during operation of the loudspeaker is also provided.
