Abstract: A detachable audio system with an interface plate mounted on a head strap, and a mounting plate assembly removably attachable to the interface plate with a portion of the strap between the plates to provide independent electrical and mechanical connections between the plates. The mounting plate assembly connects to an earbud assembly via a flexible audio cable. The mounting plate assembly has a threaded attachment member that mates with a threaded attachment member on the interface plate. A pair of electrical connectors on opposing sides of the threaded attachment member protrude from spaced apart cylindrical bosses, such that when the mounting plate is attached to the interlace plate, independent mechanical and electrical connections are provided for detachable retention and operation of the earbud assembly.

Abstract: Handheld remote control assemblies with battery retention mechanisms are disclosed. An assembly can include a body and with a substantially cylindrical aperture formed in the body and defined by a sidewall. A substantially cylindrical battery is disposed within the aperture, and a latch arm is disposed on one side of the aperture, the latch arm urging the battery toward an opposite side of the aperture. A first tab extends from an upper portion of the latch arm towards the aperture such that the first tab extends partially over an upper surface of the battery. A second tab extends from an upper portion of the sidewall at a position diametrically opposed to the latch arm such that the second tab extends partially over the upper surface of the battery.

Abstract: An earbud assembly with separate, flexible overmold sections configured to cover a seam between adjacent portions of an underling earbud housing. The earbud assembly includes a first housing member and a second housing member attached to the first housing member and forming enclosure with the first housing member that houses an audio transducer. A first flexible overmold is formed on an first exterior surface of the first housing member, and a second flexible overmold is formed on an exterior surface of the second housing member. The flexible overmolds each include an edge portion along their perimeters. Each edge portion is configured to abut the other and thereby cover the seam of the earbud housing.

Abstract: A connector assembly mountable to a head strap comprises a connector plate with an engagement portion and a threaded attachment member projecting therefrom. Two cylindrical bosses are adjacent to the attachment member and project away from the engagement portion. Spring-biased pin connectors extend through the bosses and connect electrical line coupled to the engagement portion. The pin connectors have retractable tips projecting from their respective boss for engagement with an electrical contact.
