Abstract: An in-wall or in-ceiling speaker enclosure includes a speaker back box having one or more apertures covered with an air-filtering member (e.g., open cell foam, baffling material, etc.) that may be utilized with speakers mounted on a large baffle (wall or ceiling) for reducing sound transmission to an adjacent room while significantly lowering the resonance of the speaker system and allowing the speakers to produce much greater bass energy into a desired room. Such a speaker back box includes a posterior surface, a plurality of sidewalls engaged with the posterior surface and extending anterior thereof wherein one of the sidewalls includes a first aperture. The speaker back box further includes an anterior opening oppositely disposed from the posterior surface. A flexible and resilient air-filtering member is positioned against the first aperture wherein the air-filtering member is intermediately located between the posterior surface and anterior opening.

Abstract: A sleek ceiling speaker having an annular magnetic assembly and annular dust cap through which extends an elongated actuator, which may also be a light pipe. The elongated actuator supports a variable transformer tap which is manually operated by rotating a bottom end of the elongated actuator which is expanded into a sound disperser plug. Changing the transformer tap changes the volume produced by the speaker. The elongated actuator may also support an LED board that provides light to the light pipe and to the transparent or translucent sound disperser plug. Rotating the elongated actuator may also be used to change the lighting. The housing is secured to a ceiling tile by attaching a releasably attachable outwardly extending circumferential flange to a sound funnel that supports the sound disperser.

Abstract: A loudspeaker includes a diaphragm, a frame, an attachment unit, and a fixing member. The frame has a front surface, a mounting surface disposed on a side opposite to the front surface, and a wall surface disposed in a standing manner from the mounting surface. And the frame holds an outer peripheral edge of the diaphragm. The attachment unit includes: a base portion having a top surface facing the mounting surface, a bottom surface on a side opposite to the top surface, a first side surface facing the wall surface, and a second side surface disposed on a side opposite to the first side surface; a first base rib projecting toward the wall surface from the first side surface; a second base rib projecting from the second side surface and extending to the top surface; and a locking portion disposed on a side near the bottom surface of the base portion. The fixing member penetrates the frame from the front surface to the mounting surface and is fixed to the base portion by screwing.

Abstract: Disclosed is a speaker unit which includes a speaker surface provided in a bottom surface of a cabinet section and a provisionally fastening mechanism provided on a side surface of the cabinet section. The provisionally fastening mechanism includes: an engagement section for provisionally fastening the speaker unit to the mounting part; an operating section exposed on a face side of a mounting part with the speaker unit provisionally fastened via the engagement section; and a non-shielded portion formed adjacent to the outer periphery of the speaker surface for allowing the operating section to be visible from a face side of the speaker surface. The non-shielded portion is an opening or a recess formed in a flange section projecting radially outward from the outer peripheral edge of the bottom surface of the cabinet section.

Abstract: 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.
