Abstract
An audio speaker having a removable voice coil, which may be a part of a voice coil assembly. The voice coil may be user-removable to facilitate replacement of a damaged voice coil or reconfiguration of a speaker system. Properly positioning the voice coil assembly may provide a solder-free electrical connection between the voice coil and leads that provide current to the voice coil. In some embodiments, the voice coil is user-removably attached to an inner circumferential surface of a diaphragm. In other embodiments, the voice coil is connected to the diaphragm, and the voice coil assembly and the diaphragm are both user-removably attached to a frame.
