  • Patent number: 10904669
    Abstract: A head-mounted wearable device (HMWD) provides audio output from a first speaker that is driven with a first signal and a second speaker that is driven with a second signal. Based on a volume level setting, an equalization profile and inversion frequency are determined. The equalization profile selectively amplifies or attenuates particular frequencies or ranges of frequencies. Those frequencies in the second signal that are above the inversion frequency have their amplitude inverted, relative to the first signal. When driven by the first signal and the second signal, the first speaker and the second speaker operate as acoustic dipoles below the inversion frequency and acoustic quadrupoles above the inversion frequency. Sound from the first and second speakers with frequencies above the inversion frequency exhibits destructive interference. As a result, the user wearing the HMWD is able hear audio output while audio amplitude perceived by the bystanders is significantly reduced.

  • Publication number: 20140105426
    Abstract: A narrow profile speaker unit comprises at least one speaker outputting sound towards an internal surface and through a duct with an output terminus, such as a slot, having a narrow dimension, effectively changing the cross-section of the speaker's audio output wave. A pair of speakers may face one another, outputting sound towards a common output slot. Multiple pairs of speakers may be used to form an inline speaker unit for increased sound output. A slotted speaker unit may include multiple speakers facing the same direction, towards a groundplane or reflecting surface, and having parallel apertures for allowing sound radiation. The speaker units may be integral with or attached to electronic appliances such as desktop computers or flatscreen devices, or may be used in automobiles or other contexts.

  • Patent number: 8660290
    Abstract: A display device includes an image display component, first and second speakers, and a stand. The first and second speakers are mounted to the image display component. The first and second speakers are spaced apart from each other in a first direction of the image display component. The stand includes a base with first and second sound reflecting faces. The first and second sound reflecting faces are opposite the first and second speakers in a second direction of the image display component, respectively. The second direction is perpendicular to the first direction. The first sound reflecting face slopes downward as moving away from the second sound reflecting face and forward of the image display component. The second sound reflecting face slopes downward as moving away from the first sound reflecting face and forward of the image display component.

  • Patent number: 8638959
    Abstract: A reduced acoustic signature loudspeaker system includes left and right loudspeaker assemblies that include cabinets having a plurality of sides. A full range acoustic driver/array is mounted to the first side and facing a side wall of a listening space, the second side forms the rear of the loudspeaker assembly to which is mounted a set of input terminals. The full range on-axis directional acoustic output of each loudspeaker assembly is directed outward toward the left and right side walls respectively of the listening space at an azimuth of approximately 180+/?45 degrees. No acoustic output of the loud speaker system is directed toward the listening space or directed vertically, up or down and the first sides of the left and right loud speaker assemblies are separated by a distance of at least approximately 1.0 feet.

  • Patent number: 8634586
    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.

  • Publication number: 20130343579
    Abstract: A portable loudspeaker includes a base and a speaker cap opposing the base. The base and speaker cap are interposed by a movable resonance portion. The movable resonance portion is formed in a storing state and a releasing state. The base has a resonance reflection portion to receive reverse resonance sound waves generated by a speaker. The movable resonance portion includes a first transmission channel to transmit the reverse resonance sound waves to the resonance reflection portion and a second transmission channel to transmit base sound waves generated by the resonance reflection portion from the reverse resonance sound waves towards the speaker cap. The speaker cap has a second audio outlet to output the bass sound waves.

  • Publication number: 20130208925
    Abstract: A reflector and an electronic system produce a diffuse way by creating time delays in accordance with a number sequence. An acoustical passive reflector incorporates a series of wells in its surface to transform an acoustical wave into a series of acoustical waves having a time difference based on a number sequence. The electronic signal conversion system converts a signal into a series of signals having a time difference based on a number sequence. This can be used in an audio speaker system having N×N array of speakers where N is an odd prime number, arranged to be driven by the electronic signal conversion system in which the signal is converted into a series of signals centred on the signal with at least one signal being timed to precede the signal and at least one signal to follow the signal and the signal being arranged to be sent to the central speaker in the N×N array.

  • Publication number: 20130204629
    Abstract: An voice input device includes a wave guide unit for guiding an incident sound wave, a microphone unit for converting a sound wave guided through the wave guide unit to an electrical sound signal, and a signal processing unit for processing the sound signal obtained by the microphone unit, using an acoustic characteristic given by the wave guide unit to the sound wave, in which, the wave guide unit has a structure which gives the acoustic characteristic that is different between direct sound, which is sound that reaches the microphone unit without reflecting off an internal surface of the wave guide unit, and indirect sound, which is sound that is reflected off the internal surface before reaching the microphone unit, and the signal processing unit determines whether or not the direct sound is input based on a difference in the acoustic characteristic between the direct sound and the indirect sound.

  • Patent number: 8477967
    Abstract: A speaker assembly is provided with a housing, a speaker mounted to the housing, and a reflector spaced apart from and facing the speaker. The reflector is symmetrical and has an arcuate central convex region for reflecting pressure back to the speaker for amplifying back pressure to the speaker. The reflector has a secondary region with an arcuate cross-section for reflecting acoustic vibrations past and outboard of the housing. The reflector is partially translucent, and a light source is provided adjacent the reflector for conveying light to the reflector, past and outboard of the housing for illuminating a region that receives acoustic vibrations reflected from the reflector. A media assembly is provided with a fan operably connected to a generator so that air that passes into a housing through an inlet and out of an outlet, causes the fan to rotate thereby providing a power source to a media device.
