Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
