Abstract: A method and speaker system that provides a single, user adjustable tool for controlling how and which spatialization parameters are used in a single speaker multi-driver system to enhance the sound stage. The tool creates the desired amount of audio surround effect to enhance the sound stage experience or effects in multiple sound recording mode, such as music or movies. The tool is represented in a scale that runs from ‘?10’ (less immersive) to ‘+10’ (more immersive) is set to taste by the listener and will vary with room acoustics and placement.

Abstract: A retractable gaming headphone communication system without a retractable microphone boom retracted in a simple one touch fashion. The headphone communication system is automatically disengaged and put in an off or mute mode when boom is in a deployed position and an operational communication mode when in a deployed position. the system provides an interface for digital bidirectional communication with other users. The system further provide for kinetic integration in the gaming environment.

Abstract: A modular headphone system and method of assembling a pair of headphones to satisfy individual personal fashion, comfort and performance preferences. The inventive headphone system is comprised of a plurality of modular interchangeable headphone components, each component being interchangeable and having a plurality of unique fashion, comfort or quality grade variations.

Abstract: A ceiling-mounted loudspeaker includes a horn-shaped enclosure, an acoustic driver, and a front module. The tubular or horn-shaped enclosure carries a slanted woofer or loudspeaker driver which radiates into an angled or slanted first opening. The tubular enclosure terminates at bottom in a second, circular opening substantially parallel to a second plane, wherein the woofer's slanted plane is inclined with respect to the second plane. The slanted woofer can be oval and radiates sound through the enclosure's interior lumen and outwardly through ports defined in a substantially circular baffle carrying the front module and connected to the second opening. The baffle carries a midrange and tweeter near the ceiling where they can provide enhanced sound dispersion.

Abstract: 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.

Abstract: 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.

Abstract: A loudspeaker system for use with a stereo system having right R and left L signal outputs, has a right main speaker and right sub-speaker, and a left main speaker and left sub-speaker. Inter-speaker cabling means, which connect to the R and L signal outputs, apply an R signal to the right main speaker and an R-L signal to the right sub-speaker, as well as an L signal to the left main speaker and an L-R signal to the left sub-speaker. The inter-speaker cabling means includes impedances for substantially attenuating the -R portion of the L-R signal and the -L portion of the R-L signal for signal frequencies below approximately 200 Hz.

Abstract: Apparatus for reproducing sound having a realistic ambient field and acoustic image is used in a stereophonic sound reproduction system having a left channel output and a right channel output. A right main speaker and a left main speaker are disposed at right and left main speaker locations, respectively, which are equidistantly spaced from a listening location along a listening axis perpendicular to a line joining the left and right main speakers. A right sub-speaker and a left sub-speaker are respectively disposed at right and left sub-speaker locations equidistantly spaced from the listening location, and further from the listening location than the main speaker. In one particular arrangement each sub-speaker includes a driver and a tweeter, with the driver spaced a distance approximately 50% further from the main speaker location than the tweeter. The left and right channel outputs are respectively coupled to the left and right main speakers.

Abstract: Apparatus for reproducing sound having an expanded acoustic image is used in a stereophonic sound reproduction system having a left channel output and a right channel output, which need not be binaural. A right main speaker and a left main speaker are disposed at right and left main speaker locations, respectively, which are equidistantly spaced from a listening location along a listening axis perpendicular to a line joining the left and right main speakers. The interaural time delay between the ears of a listener at the listening location with respect to the main speakers is .DELTA.t. A first right sub-speaker and a first left sub-speaker are respectively disposed at right and left sub-speaker locations equidistantly spaced from the listening location, and spaced such that sound from the sub-speakers as perceived by the ears of a listener is delayed as compared to sound from the main speakers by .DELTA.t. The left and right channel outputs are coupled to the left and right main speakers, respectively.

Abstract: A moving coil transducer such as a loudspeaker has its coil formed of multiple strand or litz wire. The structure includes a form having multiple turns of the stranded wire thereon, and the leads or ends of the stranded wire forming the coil extend continuously from the moving coil structure to attachment or terminal means carried on some portion of a fixed structure associated with the moving coil. The multiple strand wire is twisted to a predetermined lay throughout its length.

Abstract: A loudspeaker subwoofer system is disclosed which combines signals from more than one audio channel. A single enclosure mounts an active driver for each of a plurality of audio channels, which active drivers are respectively connected to each respective audio channel. A passive radiator loudspeaker is also mounted in the single enclosure. The passive radiator is acoustically coupled to the active drivers and functions as a subwoofer.
