Each ring comprises a subset of the plurality of microphones positioned at predetermined intervals along a circumference of the ring.

An example apparatus includes a speaker housing with a recessed portion having a spring-loaded lip and a set of leads to provide power to the speaker when connected to a lead, and a lead interface plate external to the speaker housing with a set of leads to match the leads in the speaker housing, and when press-fitted into the recessed portion, provides a locked position with one side of the lead interface plate secured in front of the spring-loaded lip.

A speaker assembly may be for being resiliently mounted to spaced apart frame members of a vehicle. The speaker assembly may include an elongate housing having a respective retention chamber at each opposing end, and audio speakers and associated wireless receiver circuitry carried by the housing. The speaker assembly may also include a respective inboard elastomeric body within each retention chamber, and a respective vehicle frame mounting bracket at each end of the elongate housing and to be mounted to an adjacent frame member of the vehicle. The assembly may further include respective fasteners coupling each vehicle frame mounting bracket to the elongate housing via a corresponding inboard elastomeric body so that each vehicle frame mounting bracket is resiliently coupled to the elongate housing.

A beamforming microphone array may be integrated into a wall or ceiling tile as a single unit. The beamforming microphone array includes a plurality of microphones that picks up audio input signals. In addition, the wall or ceiling tile may include an acoustically transparent outer surface on the front side of the tile, and the beamforming microphone array picks up the audio input signals through the outer surface of the tile. The beamforming microphone array may be coupled to the tile as a single unit and may be integrated into the back side of the tile.

A flat panel speaker comprises a mounting unit for mounting inside the surface and having a front and a back; a speaker unit having a flat panel, wherein the speaker unit is seated in the mounting unit and at least partially extending frontwardly from the front of the mounting unit; and at least one holding portion arranged for extending frontwardly outwards past the speaker unit and to be usable to hold the flat panel speaker in the surface during mounting. A method of mounting the flat panel speaker in a surface is also disclosed, comprising: inserting the mounting unit of the flat panel speaker through an opening defined in the surface; using the at least one holding portion to hold the flat panel speaker in the surface during mounting; and securing the mounting unit to the surface, whereby to hold the flat panel speaker in place in the surface.

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.

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.

A sound masking system includes a self-amplified loudspeaker emitter unit, with a driver and enlarged ported enclosure, sufficient to provide a frequency range down to a low frequency, such as about 125 Hz. To deliver the power, the power distribution architecture includes audio power amplifiers in the emitter housing of each loudspeaker. Raw power is delivered to each emitter unit through a cable and connectors, such as an Ethernet cable and connectors, in the same cable with the sound masking and audio signals. Inside the emitter units are electronics that efficiently convert the raw power and low level signal to drive the loudspeaker directly. The power comes from a typical desktop power supply, from which the power is combined with the sound masking and audio signals using a power injector unit that distributes the combined power and signals to loudspeakers. The loudspeakers can connect to an individually addressed sound masking network.

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.

A system is disclosed for safely and efficiently removing or returning a radio microphone from a mounting surface. The system includes a first magnet attached to the rear side of a radio microphone and a second magnet located at a desired mounting position on the mounting surface. The second magnet preferably includes an outer vinyl layer to prevent breaking or cracking of the first second magnet when returning the radio microphone to its mounting position.
