US 9,319,760 B2 · Low-profile speaker arrangements for compact electronic devices

Abstract

A portable electronic device that provides audio sound output from multiple internal speakers to a common output audio opening in a housing of the portable electronic device is disclosed. In one embodiment, the multiple internal speakers are provided in close proximity to one another, such as adjacent to one another, and serve to produce audio sound pertaining to different audio channels. The sound (i.e., pressure waves) produced by each of the internal speakers is directed into a respective acoustic chamber and output via the output audio opening in the housing. Accordingly, the acoustic chambers for the multiple internal speakers can each direct their audio sound output to the same output audio opening in the housing. The respective acoustic chambers can be formed adjacent to one another with a structural barrier serving to separate the distinct acoustic chambers.

Dependent claims

A portable electronic device comprising:

a housing comprising an audio opening;
a first acoustic component operatively coupled to a first back chamber of the housing;
a second acoustic component positioned adjacent to the first acoustic component, the second acoustic component operatively coupled to a second back chamber of the housing;
a first audio chamber defined in part by a common structural barrier and within the housing, the first audio chamber configured to interface the first acoustic component with the audio opening;
and
a second audio chamber defined in part by the common structural barrier and within the housing, the second audio chamber configured to interface the second acoustic component-with the audio opening, wherein:
the common structural barrier extends from the first and second audio components to the audio opening and isolates the first audio chamber from the second audio chamber;
the first back chamber is sealed with respect to the first audio chamber:
and
the second back chamber is sealed with respect to the second audio chamber.
