Abstract
Acoustic transducer systems involving tilt control, and methods for operating the acoustic transducer systems, are described herein. An example acoustic transducer system includes: a driver motor to generate a magnetic flux; a diaphragm operably coupled to the driver motor; a voice coil structure coupled to the diaphragm and movable in response to the magnetic flux, the voice coil structure includes: a former; a voice coil coupled to the former and movable in response to an input audio signal; and a tilt control coil coupled to the former; a tilt sensing module coupled to the voice coil structure and detects a misalignment of the voice coil structure relative to an initial alignment of the voice coil structure; and a controller for transmitting the input audio signal to the voice coil; and generating and transmitting a correction signal to the tilt control coil for minimizing the misalignment of the voice coil structure.
