Abstract
A transducer assembly including a stiffener plate having a first side and a second side; a voice coil coupled to the second side of the stiffener plate; a magnet assembly positioned along the second side of the stiffener, the magnet assembly operable to produce a magnetic field that causes a movement of the magnet assembly relative to the voice coil; and a spring suspending the magnet assembly from the stiffener plate such that the movement of the magnet assembly drives a movement of the stiffener plate.
