DETACHABLE AUDIO SYSTEM FOR HEAD-MOUNTED DISPLAYS

摘要

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.
