System and method for adjusting frequency response characteristics of a speaker based upon placement near a wall or other acoustically-reflective surface

摘要

The present invention is directed to a speaker system that more accurately reproduces audio sounds by minimizing the negative effects from sound reflecting from a nearby wall. The invention is embodied in both methods and apparatus of differing forms. In one embodiment, the invention comprises a method that receives an electrical signal embodying an audio signal to be communicated to the speaker, and modifies the electrical signal by a measure that is based upon a separation distance separating the speaker and a wall. In another embodiment, the invention comprises a driver circuit for a an audio amplifier that, in turn, drives a speaker. The driver circuit includes a circuit configured to receive an electrical signal embodying an audio signal to be communicated to the speaker, and a signal modifying circuit configured to modify the electrical signal by a measure that is based upon a separation distance separating the speaker and a wall.
