The electrical device is an electrical device that is mounted on a wall of a building, the electrical device including: an actuator that vibrates; and absorbing member that absorbs vibration of the actuator and is positioned behind the actuator in a predetermined direction, where a direction from a back side to a front side of the wall is defined as a direction toward a front in the predetermined direction in a state where the electrical device is mounted on the wall.

An elliptically shaped speaker has a driver assembly which may include a woofer driver and a tweeter driver. The speaker has a uniquely designed bridge member. The bridge member acts both as a structural element and waveguide for the tweeter. It has a specific elongated, elliptical shape that allows the speaker to be inserted into a corresponding cut-out opening in a wall, ceiling or any other structural panel, then rotated behind the panel and re-inserted from behind into the opening, thereby providing a secure seal and exact positioning within the panel. The resulting system allows for a low frequency speaker to be installed behind the panel with a noticeably smaller opening than the total size of the speaker.

A wireless sound-emitting device includes a housing adapted to be coupled to a wall at a source of electric power, a loudspeaker positioned at a periphery of the housing, a control module outputting an electric audio signal to the at least one loudspeaker, and a wireless communications module in electrical communication with the control module. The loudspeaker emits acoustic signals in a direction parallel to the wall, when the housing is coupled to the wall, with the acoustic signals reflecting off the wall. The device may produce a sound masking noise or play a sound recorded on an internal memory. The device may include an electric plug or be adapted to replace an electric outlet faceplate. The device may have electric pass-through outlets and may be powered by the source of electric power. The device may be controlled remotely, for example via an Internet of Things (IoT) platform.

In one example embodiment, a device mounting system is provided for in-wall and/or in-ceiling use in residential and commercial structures, suitable for both retro-fit and new construction applications. The system includes a mounting ring and a device can. The mounting ring is installed directly into a hole cut at a selected location in the wall or ceiling or into a pre-construction bracket arranged in the wall or ceiling. The device can is later inserted into the mounting ring and retained therein by a combination of a number of magnets that are attracted to a mounting ring flange and a number of spring clips that engage an inner face of a mounting ring body.

A commercial lighting system, the system comprising, an integral housing adapted to be coupled to a ceiling of a building, a lighting unit mounted to the integral housing and a loudspeaker assembly mounted to the integral housing, the loudspeaker assembly comprising a low directivity index, and oriented to provide an acoustic sound signal from the integral housing to a listener in an area of the building comprising the ceiling.

Elevator systems including an elevator car moveable within an elevator shaft, the elevator car having a first elevator car component, the first elevator car component having a first side facing an interior of the elevator car and a second side opposite from the first side and a structural sound-generation system. The structural sound-generation system having at least one audio actuator coupled to the second side of the first elevator car component and an audio system controller in communication with the at least one audio actuator. The structural sound-generation system is configured to generate vibrations within the first elevator car component such that sound waves are produced therefrom and projected into the interior of the elevator car.

A loudspeaker to be attached to an attachment member, the loudspeaker including: a temporary joint pin which is inserted into a temporary joint hole and temporarily holds the loudspeaker in a suspended state. The temporary joint pin includes a rod-like portion backwardly projects from a rear end surface of a frame; a tilted surface portion which is part of an inner circumferential surface of a circumferential surface of the rod-like portion to be brought into contact with the temporary joint hole, and is tilted to become closer to the central axis of the rod-like portion from a base end toward a distal end of the rod-like portion in a direction of projection; and a flanged portion which is adjacent to the tilted surface portion at the distal end of the rod-like portion, protrudes in a direction crossing the direction of projection, and catches onto the attachment member.

Audio systems and methods for obtaining location information are disclosed. A portable, wireless speaker that may include a beacon that a user may activate to remotely trigger a request for shot information, which may include location information of the user or speaker. The beacon may be wirelessly coupled to the speaker. The speaker may receive location information from a remote device, such as a GPS-enabled mobile phone. The shot information may be converted into an audio format for playback by the speaker. The speaker may pause the playback of the speaker to play out the shot information.

A mount for a soundbar includes a positioning column, and a positioning mechanism operably coupled to the positioning column. The positioning column is selectively shiftable relative to the positioning mechanism. A pair of mounting arms is coupled to the positioning mechanism, the mounting arms adapted to attach to a television and a sound bar interface is operably coupled to the positioning column,

To provide an electric light bulb type light source apparatus capable of reducing backlash, which results in noise, and improving the sound quality of a speaker. The electric light bulb type light source apparatus may include a speaker, a light source unit, a supporting unit, a casing, and a base. The supporting unit may support the speaker. The supporting unit may include a base portion. The base portion may include a tapered surface and a supporting surface that supports the light source unit. The casing may include an abutting surface that abuts against the tapered surface of the base portion. The base maybe used for supplying a power to the light source unit and the speaker.
