摘要： Driver for an acoustic transducer having a moving coil of substantially equal length to the air gap. The air gap may itself be extended in length using an upper or lower lip, or both. A stationary coil is also provided. The moving and stationary coils can be controlled by suitable control blocks to form an electromagnet-based transducer with reduced distortion.

摘要： This invention relates to acoustic drivers with stationary and moving coils. Time varying signals are applied to the moving and stationary coils to control the movement of a diaphragm, which produces audible sound. The time varying signals correspond to an input audio signal such that the sound corresponds to the input audio signal. Some of the described embodiments include multiple moving coils, multiple stationary coils or both. Some embodiments include feedback for adjusting one or more of the signals based on a characteristic of the acoustic driver. Various compensation and other features of the invention are also described in relation to various embodiments.

摘要： A system for and a method of outputting sound having a variable apparent source distance and/or width. The system may be used in a vehicle and the apparent source distance may be varied depending on parameters of the driving style or the drivers behaviour, so that the less concentration or perceptual/cognitive surplus the driver has for listening to the audio, the narrower will the apparent source width be.
