Abstract
An electro-acoustic transducer includes a cone, a voice coil connected to the cone, and magnetic circuit that defines a gap within which the voice coil is disposed. The magnetic circuit is configured for creating magnetic flux across the gap for the voice coil to interact with, thereby to drive motion of the cone. A conductor is included for providing an input signal to the voice coil. A first portion of the conductor is fixedly secured to the magnetic circuit such that the first portion of the conductor does not move relative to the magnetic circuit while the cone is in motion.
