Abstract
A loudspeaker having a compressible lead wire is described. The lead wire carries an electrical audio input signal to a voice coil. The electrical audio input signal drives the voice coil to oscillate in an axial direction. The compressible lead wire includes an elastic portion that stretches and compresses in the axial direction to allow the voice coil to oscillate freely. The elastic portion includes several compressible elements that are located within a cavity of the loudspeaker. The compressible elements extend through the cavity in the axial direction. Other aspects are also described and claimed.
