Abstract
An electronic device is disclosed that includes one or more sealed audio modules that are unaffected by changes in the internal pressure within the electronic device. The audio modules can also include one or more features that increase the audible bandwidth of the electronic device.
Claims20
An audio module for an electronic device, the audio module comprising:
- a driver assembly comprising:
- a diaphragm defining a speaker plane;
- and
- a voice coil attached to the diaphragm and positioned adjacent one or more magnets;
- and
- an enclosure surrounding the driver assembly and defining:
- a front volume positioned on a first side of the speaker plane and coupled to a sound port;
- a back volume positioned on the first side of the speaker plane and on a second side of the speaker plane;
- and
- a resonant cavity coupled to the front volume via a resonant cavity port and separated from the back volume by a resonant cavity cover.

An audio module for an electronic device, the audio module comprising:
- a frame;
- a driver assembly disposed within the audio module and including a diaphragm that defines a speaker plane;
- a front cover attached to the frame and positioned parallel to and spaced apart from the diaphragm in a first direction, wherein the front cover, the diaphragm and the frame define a front volume;
- a back volume positioned at least partially on a first side of the speaker plane and at least partially on a second side of the speaker plane;
- a front volume aperture coupled to the front volume;
- a rear cover attached to the frame and positioned parallel to and spaced apart from the diaphragm in a second direction that is opposite the first direction;
- and
- a substantially U-shaped channel that couples acoustic energy from the front volume aperture to a sound port defined by the frame.

An electronic device comprising:
- a device enclosure;
- a display assembly coupled to the device enclosure, the combination thereof defining an interior volume, wherein the display assembly includes a touch sensitive layer and a force sensitive layer;
- and
- an audio module disposed within the interior volume and comprising:
- (1) a driver assembly including:
- a diaphragm defining a speaker plane;
- and
- a voice coil attached to the diaphragm and positioned adjacent one or more magnets;
- and
- (2) an audio module enclosure surrounding the driver assembly and defining:
- a front volume coupled to a speaker opening formed in the device enclosure;
- a back volume positioned on the first side of the speaker plane and on a second side of the speaker plane;
- and
- a resonant cavity coupled to the front volume via a resonant cavity port and separated from the back volume by a resonant cavity cover.
