Abstract: A plurality of speakers are carried on a generally vertical board. The board is carried for pivotal motion about a vertical axis. The board is housed within an enclosure permitting sound radiation in all directions. Some speakers are directed to face oppositely from other speakers, all of which having a different operating frequency. One of the speakers is driven by a separate amplifier. The system is truly omnidirectional with acoustical phase problems being overcome because all but the high frequency drivers or tweeters have the same size.

Abstract: A sound bar having a mounting assembly configured to pivotally secure the bar. The sound bar includes an elongated, at least partially hollow, housing. The housing has a body extending between two opposing ends. A speaker array is positioned in the body. At least one speaker is positioned in at least one end of the bar. The end speaker(s) are preferably bass speakers in fluid communication with the hollow housing. A grill is preferably positioned over at least one of the housing ends. The grill preferably has a center hub affixed to an outer rim by spokes defining open spaces in the grill to facilitate the emission of sound. A mount is attached to the sound bar to secure the bar to a structure while allowing the bar to pivot along its longitudinal axis. Preferably, the mount is secured to the center hub of the grill.

Abstract: The sound amplifier system disclosed herein can transmit discrete electronic output signals via discrete channels to different speaker types or different speaker sets. For example, in some situations a guitarist may want to play a clean tone through a speaker type designed to play clean tones. In other situations, a guitarist may want to play a distorted tone through a speaker type designed to play distorted tones. The sound amplifier system allows the guitarist to select which speaker type they wish to transmit their guitar output signal to depending on what sound they want to play. In addition, this disclosure also concerns various embodiments of a sound amplifier system which have articulating speakers that may be tilted vertically or horizontally.

Abstract: A system and method is described for determining whether a loudspeaker device has relocated, tilted, rotated, or changed environment such that one or more parameters for driving the loudspeaker may be modified and/or a complete reconfiguration of the loudspeaker system may be performed. In one embodiment, the system may include a set of sensors. The sensors provide readings that are analyzed to determine 1) whether the loudspeaker has moved since a previous analysis and/or 2) a distance of movement and/or a degree change in orientation of the loudspeaker since the previous analysis. Upon determining the level of movement is below a threshold value, the system adjusts previous parameters used to drive one or more of the loudspeakers. By adjusting previous parameters instead of performing a complete recalibration, the system provides a more efficient technique for ensuring that the loudspeakers continue to produce accurate sound for the listener.

Abstract: A modular audio assembly for use with a vehicle headrest includes a speaker assembly including a support member arranged to be rotatably mounted to the vehicle headrest, and a speaker module coupled to the support member, the speaker module including a housing having a front face and at least one speaker mounted therein for generating audio output. An actuator is operably connected to the speaker assembly and configured to position the speaker assembly in an inactive position with the front face generally adjacent a lateral side of the vehicle headrest and in an active position with the speaker assembly rotated away from the lateral side of the vehicle headrest and the front face oriented in an inward direction.

Abstract: A wearable device can provide an audio module that is operable to provide audio output from a distance away from the ears of the user. For example, the wearable device can be worn on clothing of the user and direct audio waves to the ears of the user. Such audio waves can be focused by a parametric array of speakers that limit audibility by others. Thus, the privacy of the audio directed to the user can be maintained without requiring the user to wear audio headsets on, over, or in the ears of the user. The wearable device can further include microphones and/or connections to other devices that facilitate calibration of the audio module of the wearable device. The wearable device can further include user sensors that are configured to detect, measure, and/or track one or more properties of the user.

Abstract: An array frame adapter for positioning flying speaker arrays in sound rigs enables a user to expediently create a desired tilt angle of an entire speaker array by singlehanded action applied to rotate a threaded drive member. The threaded drive member is operationally coupled to a lever arm which is caused to pivot as the threaded drive member is rotated. The lever arm is caused to travel incrementally between a first position and a second position within an arcuate track to produce a maximum tilt angle of the suspended array.

Abstract: Embodiments are described for a high-frequency waveguide that improves the performance of large-scale surround sound and immersive audio environments. A horn waveguide is configured to be asymmetric about one of a vertical axis and horizontal axis of the waveguide to form an asymmetric horn waveguide. A spherical enclosure surrounds the asymmetric horn waveguide to form a horn speaker, and a three-axis mounting system is configured to fix the horn speaker to one of a wall or ceiling surface of the venue, wherein the mounting system facilitates rotating the horn speaker to a location that provides maximum coverage of the venue within the passband of the asymmetric horn waveguide.

Abstract: A headset is described which includes a speaker capsule and a headband connected to the speaker capsule with a first sensor on the headset for sensing an angle of rotation of the speaker capsule relative to the headband, and a second sensor on the headset for sensing a Don/Doff event. The angle of rotation sensor can indicate whether the speaker capsule on the headband is in a wearable position or in a non-wearable position. Logic controls an operation of the headset in response, such as changing power management modes, signaling host devices, and enabling/disabling the second sensor.
