AN ELECTRICAL SYSTEM FOR A SPEAKER AND ITS CONTROL

摘要

An electrical apparatus includes a frame, a speaker connected to the frame, a digital signal processor in communication with the speaker to receive audio data and control data to control the speaker, the digital signal processor connected to the frame, and a lamp base coupler electrically connected to the speaker and receiver, the lamp base coupler detachably connectable to a power source, when the power source is present. A method for creating a diffused sound field by use of a specially designed diffuser is presented. A method of steering the diffused sound field includes, broadcasting at least one calibration audio signal through each of a plurality of speakers (M) in an audio system, receiving the at least one calibration audio signal in a plurality of microphones spaced apart and positioned about at a listening position, and calculating respective relative speaker placement angles relative to the listening position between each of the plurality of speakers in response to receipt of the at least one calibration audio signal in the plurality microphones, wherein the angular location of each of the plurality of speakers is determined in relation to the listening position to facilitate virtual channel positioning.
