Abstract: A system for magnetically securing an electronics enclosure proximate a surface of a separate structure. The system includes a mounting apparatus that has a first surface, a second surface, and an interface structure that is constructed and arranged to allow the mounting apparatus to be secured to the surface of the separate structure, with the first surface of the mounting apparatus closer to the surface of the separate structure than is the second surface of the mounting apparatus. One or more magnets are fixed to one or both of the mounting apparatus and the electronics enclosure such that the one or more magnets are arranged to magnetically couple the electronics enclosure to the mounting apparatus.

Abstract: Audio network interface devices that are configured to be used with different types of microphones, and analog or digital audio devices. There is a housing that carries at least one set of electrical connectors adapted to be electrically connected to a microphone or audio device. The microphone connector including at least one general purpose input, at least two general purpose outputs and DC power. There is a first network connector that is adapted to provide connection to a data network, and a second network connector that is adapted to provide connection to a different electronic device. A microphone phantom power source is configured to provide phantom power to a microphone that is connected to a set of electrical connectors. A processing system is configured to cause the conversion of input and output signals from/to a microphone or other audio device that is connected to a set of electrical connectors, to/from digital output signals that are provided to the first network connector.

Abstract: A speaker includes a housing, at least one electro-acoustic driver including a diaphragm, and a cover secured to one or more of the housing and driver. The cover is configured to partially extend over the diaphragm to affect an associated cavity resonance frequency of an air cavity adjacent to the diaphragm.

Abstract: An apparatus for positioning two speakers relative to each other includes a link member with a first securing through hole and a first plurality of adjusting through holes. A first anchor plate which can be secured to a first speaker has a second securing through hole. A first pin is able to be passed through the first and second securing through holes to secure the link member and the first anchor plate together at a back, central location of the speaker. A second anchor plate which can be secured to a second speaker has a second plurality of adjusting through holes. A second pin is able to be passed through one of the first plurality of adjusting through holes and one of the second plurality of adjusting through holes to secure the link member and the second anchor plate together.

Abstract: The technology described in the document can be embodied in a speaker that includes one or more drivers, and an acoustic horn that includes a first side panel and a second side panel. Edges of the first and second side panels defines an opening for receiving acoustic outputs from one or more drivers. The speaker also includes a manifold disposed between the opening and the one or more drivers, the manifold including a plurality of acoustic passages for connecting the opening to each of the one or more drivers, and an adaptor. The adaptor is disposed between the manifold and the acoustic horn, and includes multiple apertures for the plurality of acoustic passages. The adaptor is configured to conform to a profile of the opening while maintaining a seal between the acoustic horn and the plurality of acoustic passages.
