Abstract

A cover for a display device and a case for a communication device are provided. The cover comprises: external dimensions shaped to fit said cover in a case for said communication device; a top surface; a bottom surface; a non-opaque region adapted to cover said display device allowing a user to see said display device; and a region defining a top of an enclosure cavity for a speaker associated with said communication device. Sound holes in the cover are preferably present. A recess around the region is provided for fitting with a cover for the recess. A communication device comprising the cover is also provided. The case comprises: an exterior frame; a first opening in the frame; an internal wall defined within the exterior frame; a first cavity located in the internal wall; and an air channel to connect the first cavity to a region in the case.

Claims (33)

1. A cover system for a display device and a speaker of a communication device, the cover system comprising:

a first cover having

external dimensions shaped to fit in a recessed region of a case for said communication device, said recessed region bounding a first opening through which said display device projects and a second opening through which said speaker projects;

a top surface;

a bottom surface;

a non-opaque first region adapted to cover said first opening through which said display device projects;

a second region defining a top of an enclosure cavity for said second opening; and

at least one sound hole located about said second region, said at least one sound hole extending from said top surface through said first cover to said bottom surface and connecting to said enclosure cavity; and

a second cover to fit over said second region, said second cover being shaped to allow passage of air from above said second cover to said at least one sound hole on said first cove,

wherein said first cover does not cover an opening for a keypad for said communication device.

2. The cover system for a display device for a communication device as claimed in claim 1 , wherein said second region has a recess extending inwardly from said top surface into said first cover.

3. The cover system for a display device for a communication device as claimed in claim 2 , wherein said recess has a stunted hexagonal shape on said first cover.

4. The cover system for a display device for a communication device as claimed in claim 3 , wherein said second cover has a stunted hexagonal shape to fit said recess.

5. The cover system for a display device for a communication device as claimed in claim 2 , wherein said second cover has a stunted hexagonal shape to fit said recess.

6. A case for a communication device, the case comprising:

an exterior frame;

a first opening in said frame for providing access to a display for said device through a front face of said device;

an internal wall defined within said exterior frame spanning between lateral sides of said exterior frame to define a boundary between a region and said first opening to receive a speaker for said device to allow said speaker to project sound towards said front face;

a first cavity located in said internal wall about said region shaped to provide acoustic tuning for said speaker;

an air channel to connect said first cavity to said region;

a second cavity defined in said external frame to provide acoustic tuning for said speaker; and

a second air channel defined in said external frame connecting said second cavity to a region below said speaker,

wherein said first cavity is covered by a first cover for said communication device when said cover is affixed to said external frame.

7. The case as claimed in claim 6 , further comprising:

a continuous recess running around said opening for receiving said first cover in said frame, said first cover covering said first opening for said display and said region for said speaker and providing a part of said front face of said device.

8. The case as claimed in claim 6 , wherein said second cavity is covered by a printed circuit board (PCB) when said PCB is assembled with said external frame.

9. The case as claimed in claim 6 , wherein said second cavity spans both sides of said second region.

10. The case as claimed in claim 6 , wherein said first cavity is a Helmholtz cavity.

11. The case as claimed in claim 6 , further comprising:

a second cavity defined in said external frame to provide acoustic tuning for said speaker; and

a second air channel connecting said second cavity to a region below said speaker.

12. The case as claimed in claim 11 , wherein said second cavity is covered by a printed circuit board (PCB) when said PCB is assembled with said external frame.

13. The case as claimed in claim 11 , wherein said second cavity spans both sides of said second region.
