    摘要: A dual purpose loudspeaker incorporating at least two audio signal inputs and at least one switch is adapted to receive and reproduce either a single audio signal input or two audio signal inputs according to the position of the switch. A switch slide mechanically linked to the switch is provided which blocks one of the audio signal inputs when the switch is in the single-channel position, thereby preventing erroneous connection to the blocked audio signal input.

    摘要: A compact audio reproduction system for two input signals includes at least four loudspeakers disposed at the vertices of a quadrilateral not more than two feet on any side and such that no two loudspeakers are located at a distance from one another which is less than one-fourth the greatest distance between any two loudspeakers. The two input signals are connected to alternate speakers such that no two loudspeakers at adjacent vertices of the quadrilateral produce the same signal such that a listener at an arbitrary location perceives a sound source larger than the quadrilateral and significant stereo image. The signals received by two loudspeakers located at adjacent vertices may receive signals which are equalized separately from the signals received by the other loudspeakers for the purpose of reducing comb filtering and improving the tolerance of the device to placement near walls and other obstructions. Two loudspeakers may be delayed by a time corresponding to a sound distance at least equal to the shortest distance between two loudspeakers and not greater than the longest distance between two loudspeakers, for the purpose of reducing comb filtering and improving the perception of large sound source size and stereo imaging for listeners at arbitrary locations.

    摘要: A single enclosure loudspeaker system projects multi-channel surround sound into a listener's room, and so replaces multiple conventional surround channel loudspeakers. The loudspeaker system includes a pair of opposing multi transducer arrays oriented laterally toward walls or reflecting surfaces (relative to the viewing axis) within the media space. The multi-element arrays are housed in a single self-powered loudspeaker enclosure along with a single (or multiple) low-frequency electro-acoustical drive element(s). In one embodiment of the invention, surround channel program material is pre-processed by an integrated wireless transmission device that performs certain digital signal processing and channel mixing steps in advance of wireless surround signal broadcast to a receiver.

    摘要: A multi-element single enclosure loudspeaker system uses all of the available driver elements in a linear array of loudspeaker drivers for purposes of reproducing center channel program material, whether discrete within a multichannel mix (such as Dolby Digital 5.1™) or derived from a 2-channel mixdown via any appropriate means (such as SRS™ or Dolby ProLogic™ algorithms), in a manner that provides optimized intelligibility of dialog, improved overall clarity, natural timbre and dynamics of music or other effects and wide bandwidth for a wide range of seating/viewing locations for (domestic) home theater environments.

    摘要: A system and method are provided for smoothing the in-room acoustic magnitude response of an audio reproduction system. An in-room acoustic magnitude response analysis is performed to determine a room resonance induced peak associated with an audio signal. A replica of the audio signal is filtered at the room resonance induced peak. The filtered replica signal is added with the audio signal. Through this, smoothing of the room resonance induced peak may be achieved, such that a subjective impression of transient response and dynamics of the audio signal are preserved.
