A wireless mobile electronic device includes a first housing and a first acoustic chamber disposed within the first housing. A sound generator, within said first housing, is acoustically coupled to the first acoustic chamber. Additionally, a first acoustic port defines an opening into the first acoustic chamber. The acoustic port includes a first mating structure configured for mating with a second mating structure of a second acoustic chamber, exclusive of said first housing.

Attachable external acoustic chambers for a mobile device

An external acoustic chamber () for attachment to a mobile device () is provided. The external acoustic chamber () optimizes the audio performance of the mobile device () thus reducing the need for signal equalization and/or hardware to amplify the sound signal. The mobile device () includes a loudspeaker () and a first acoustic chamber () acoustically coupled to the loudspeaker (). The external acoustic chamber () comprises at feast a second acoustic chamber () which penetrates the first acoustic chamber () adding volume to the first acoustic chamber (). The combined greater volume reduces the dampening of loudspeaker () caused by the pressure in the first acoustic chamber (). The result is an improvement in the frequency response of loudspeaker () approaching the natural frequency response of loudspeaker (). The at least second acoustic chamber () is sized and shaped so that a first exterior surface portion of the acoustic chamber () covers or is flush with the battery () installed in the housing () of the mobile device (). The first, exterior surface portion is substantially aligned with a second exterior surface portion enclosing the at least second acoustic chamber ().

A device that includes a circuit board () and a first electrical contact (). The first electrical contact can include a jacket () and a magnetic member () that slideably engages the jacket. The jacket can be soldered, fastened or clamped to the circuit board, or conductively attached to the circuit board in any other suitable manner. A first portion of the jacket can be attached to the circuit board so as to provide electrical continuity between the jacket and a conductive portion of the circuit board. The magnetic member can include a flange () and can be translationally moveable between a first position in which the flange does not engage the jacket and a second position in which the flange does engage the jacket.

An acoustic seal system (). The system () includes a flexible sealing element () having a ridge () for engaging a cover () with a sealing interference fit, a plate () in which the flexible sealing element () is secured to the plate () and a mesh () for controlling particle contamination. The mesh () is secured to the plate (), and the plate () and at least a portion of the flexible sealing element () are secured to a portion of an inner housing (). The portion of the flexible sealing element () engages the portion of the inner housing () with a sealing interference fit. When the cover () engages the inner housing (), the flexible sealing element () provides an acoustic seal between the cover () and the inner housing ().
