Claim:
1. An electro-acoustic transducer comprising: a cone; a voice coil connected to the cone; a magnetic circuit including a front plate and defining a gap within which the voice coil is disposed, the magnetic circuit being configured for creating magnetic flux across the gap for the voice coil to interact with, thereby to drive motion of the cone; and a conductor for providing an input signal to the voice coil, wherein a first portion of the conductor is fixedly secured to the front plate such that the first portion of the conductor does not move relative to the magnetic circuit while the cone is in motion, and wherein at least the first portion of the conductor is electrically isolated from the front plate, wherein the conductor further comprises a second portion that is displaceable relative to the front plate, and wherein the front plate defines a radial slot which accommodates relative movement of the second portion of the conductor.
