Abstract: Acoustic transducer systems involving position sensing, and methods of operating and providing the acoustic transducer systems, are described herein. The described systems include a driver motor with a voice coil structure coupled to a diaphragm, the voice coil structure movable within an air gap in response to a magnetic flux; a position sensor to generate a position signal to represent a displacement of the diaphragm; and a system controller to modify an input signal based on the position signal and transmit the modified input signal to a voice coil so the voice coil can move in response to the modified input signal. The position sensor can generate the position signal based on optical sensing or strain measurements.

Abstract: Acoustic transducer systems are described herein and in particular, acoustic transducer systems involving high displacement are described. An example acoustic transducer system includes an acoustic driver, a diaphragm position sensing module for generating a position signal corresponding to a displacement of a diaphragm of the acoustic driver, and a controller operable to: receive an input audio signal; generate a control signal based at least on the input audio signal and the position signal; and transmit the control signal to a voice coil operably coupled to the diaphragm so that the voice coil moves within an air gap within the acoustic driver at least partially in response to the control signal. A height of the voice coil can correspond substantially to a gap height in some embodiments.
