First Claim
Patent Images
1. 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.

10. 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 positioned within a speaker opening in the frame; 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 front volume aperture positioned transverse to the diaphragm such that sound from the diaphragm exits the front volume in a direction parallel to the diaphragm; 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; a substantially U-shaped channel that couples acoustic energy from the front volume aperture to a sound port defined by the frame; and a panel of acoustic mesh positioned within the substantially U-shaped channel and having a perimeter embedded within a portion of the frame. - View Dependent Claims (11, 12, 13, 14)
