A loudspeaker arrangement comprises a frame including at least two mounting fixtures and a connecting element. The connecting element connects the at least two mounting fixtures to each other. The loudspeaker arrangement further comprises at least two loudspeakers. Each of the at least two loudspeakers is arranged in a different one of the at least two mounting fixtures. The loudspeaker arrangement further comprises an amplifier configured to amplify audio signals to be reproduced by the at least two loudspeakers. The amplifier is mechanically coupled to the connecting element between the at least two mounting fixtures.

A voice augmentation device disposed at a specific position with respect to a droplet suppressing member disposed between a speaker and a listener to suppress droplet generated from at least one of a mouth and nose of the speaker causes a base vibration input part to receive vibration from at least one of the droplet suppressing member and air between the droplet suppressing member and the base vibration input part, causes a mounting part to receive the vibration from the droplet suppressing member, causes a coupling part to receive the vibration from at least one of the droplet suppressing member and air between the droplet suppressing member and the coupling part, and causes a base vibration output part to transmit the vibration received by the base vibration input part, the mounting part, and the coupling part to air on a side of the listener.

A guitar holder with a built-in guitar amplifier for enabling convenient guitar practice and/or play with a compact, space-saving footprint. The guitar holder may comprise any of a variety of guitar holders, including but not limited to a guitar stand and/or a guitar wall hanger.

An audio system includes an audio/video receiver, a power supply/wireless audio distribution assembly connected to the audio/video receiver, speaker wire, and speakers compatible with the power supply/wireless audio distribution assembly.

A speaker unit that has a housing, a lower substrate that is fixed to the housing, a plurality of first ultrasonic vibrators that are arranged on the lower substrate, an upper substrate that is fixed to the housing and has a plurality of openings (OP) formed therein at locations that correspond to the first ultrasonic vibrators, and a plurality of second ultrasonic vibrators that are arranged on the upper substrate.

A light speaker structure with a ring handle includes a speaker body, a speaker enclosure, a lighting mechanism and an auxiliary mechanism. The speaker body is mounted within the speaker enclosure, and the auxiliary mechanism is mounted on the speaker enclosure. The lighting mechanism includes a lampshade, a light strip, and LED beads. The light strip is mounted within the lampshade. The LED beads are fixedly connected to the light strip and electrically connected to the speaker body. The light strip is disposed in a laterally inverted C-shape around the speaker enclosure. The lampshade covers the light strip, so that the light strip is held between the lampshade and the speaker enclosure. The light strip and the lampshade are so shaped that they can be arranged around the speaker enclosure, thereby achieving a better lighting effect, providing a larger lighting area and producing a stereoscopic effect.

Embodiments disclosed herein include headphone devices with spatially diverse antennas employing multiple operational modes and antenna switching policies. The headphone device may identify a current mode of operation and wirelessly communicate with at least one external device based at least in part on the current mode of operation. Further, operating in a first mode of operation, the headphone device may cause switching circuitry to selectively couple a first antenna to the common port in accordance with a first antenna switching policy. While operating in the second mode of operation, the headphone device may cause circuitry to selectively couple a second antenna to the common port in accordance with a second antenna switching policy that is different from the first antenna switching policy.

Disclosed is a method for acclimating animals in a habitat area to specific sounds caused by humans, specifically motorized vehicle sounds. Also disclosed is a device for acclimating animals in a habitat area to specific sounds caused by humans acclimating Recorded sounds are played back at specified times using the device, which is remotely positioned in the habitat area. This playback, when conducted for a sufficient period of time, acclimates the animals in that habitat to the recorded sounds.

Examples disclosed herein include a speaker. The speaker may include a group of microphones and a processor. The processor may determine a first speaker-channel identifier for a multi-speaker system at least partially responsive to a first tone captured at the group of microphones. The processor may also determine a position of a source of the captured first tone relative to the speaker at least partially responsive to position information derived from the captured first tone. The processor may also determine a second speaker-channel identifier at least partially responsive to the first speaker-channel identifier and the position of the source of the captured first tone. The processor may also determine speaker settings at least partially responsive to the second speaker-channel identifier. Related devices, systems and methods are also disclosed.

Provided is a guitar case that can include a body for placement of a guitar; a translucent or transparent window where a portion of the guitar is visible from outside of the case; and a speaker; wherein the guitar placed inside of the case is configured to play over the speaker with a wired or wireless connection. The guitar case can further include a panel or a screen. The screen can be a touch-screen. The panel can be configured to move to allow access to electronics inside of the case. The panel can pivot out. The guitar case can further include a door, the door having the window. The guitar case can further include a camera or a microphone. The case can be configured so that a guitar is placed at an angle of less than vertical.
