Abstract:
An electro-acoustic driver comprises a sleeve having a first end and a second end; a first wire exit opening at a first position of the sleeve; a second wire exit opening at a second position of the sleeve; a voice coil within the sleeve; a magnetic assembly in magnetic communication with the voice coil in the sleeve between the first end and the second end; and a conductive wire of the voice coil having a first region at the first wire exit opening, a second region at the voice coil, and a third region between the first and second regions configured as a helix about the acoustic assembly. The third region of the conductive wire is substantially unsupported between the voice coil and the first wire exit opening.
