Various implementations include portable speakers with detachable wireless transmitters. In some particular aspects, a portable speaker includes an enclosure housing: at least one electro-acoustic transducer for providing an audio output, a processor coupled with the at least one transducer; an audio input module coupled with the processor for receiving audio input signals; and an input channel for receiving a hard-wired audio input connection at the enclosure; at least one wireless transmitter detachably housed in the enclosure and in communication with a corresponding wireless input channel for receiving audio input from a source device.

Portable speaker with integrated wireless transmitter

A waveguide assembly for a loudspeaker is provided. The waveguide assembly includes a plurality of panels and a plurality of trays, which together at least partially defines a waveguide. One or more of the panels are arranged to be movable relative to the trays to adjust a coverage pattern of the waveguide.

Adaptable waveguides

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.

Electronics enclosure mounting

A connection pin comprises an elongated neck and a base at an end of the neck. The base may include a first portion, a second portion between the first portion and the neck, and a lip between the first portion and the second portion. A distance between the lip and the neck may be less than a radius of the neck. The connection pin may further comprises at least one spring-loaded element along the neck for maintaining the connection pin in a temporary fixed position relative to another element in which the neck is constructed for insertion and an actuator that retracts the at least one spring-loaded element when in a pressed position. An end of the actuator does not exceed a surface of the base when the actuator is in an unpressed position. An opening in the base may be threaded.

Low profile connection pin for audio system

A speaker includes a housing, a member secured to the housing, and a locking pin which passes through a first portion of the speaker. The member substantially covers at least two sides of the locking pin. The member thus provides some protection against the locking pin unintentionally coming into contact with another object. The member has two or more feet which are secured to the member and which can support the speaker on a substantially horizontal surface when the speaker is oriented such that the member is facing the surface.

Speaker

An array of speaker modules includes a first speaker module having at least one electroacoustic driver and a housing that together define a first acoustic cavity having a first cavity volume. The array also includes a second speaker module having at least one electroacoustic driver and a housing that together define a first enclosed volume that is greater than the first cavity volume by a first volume difference. The second speaker module includes a first internal enclosure having a first internal volume that is substantially equal to the first volume difference. The portion of the first enclosed volume that is outside the first internal volume defines a second acoustic cavity having a second cavity volume that is substantially equal to the first cavity volume. This configuration enables the performance of low frequency acoustic drivers in the speaker modules to be substantially matched without requiring complicated alternative approaches for matched performance.

Speaker modules having different module housing geometries and similar acoustic properties

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. An internal power supply is configured to derive power from the data network connected via the first network connector, and provide derived power to the microphone phantom power source, DC power to a microphone connector, and the processing system.

Audio network interfacing

Audio network interface device

In one aspect, an apparatus for connecting a first object to a second object includes a member with a plurality of teeth and an attachment element which includes a plurality of teeth which can engage with the teeth of the member. One of the member and the attachment element are securable to one of the first and second objects. The other of the member and the attachment element are securable to the other of the first and second objects. A securing device prevents the member's teeth from disengaging with the attachment element's teeth such that the attachment element is secured to the member at a certain location along the member. As such, the attachment element can be secured to the member at a plurality of different locations along the member so that the first object can be connected to the second object in a plurality of different positions.

Connection apparatus

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.

Mitigating effects of cavity resonance in speakers

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.

Relative positioning of speakers

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.
