Abstract
A speaker system for an electronic device includes a keypad with keys, a housing with first spaces for receiving respective ones of the keys, and a flat speaker located under the keypad. The keys and the first spaces are sized such that there are gaps between the keys and the housing when the keys are received within the first spaces. The speaker is co-planar with the keypad and when sound is projected from the speaker, it is emitted through the gaps between the keys and the housing.
Claims15
An electronic device, comprising:
- a keypad having a plurality of keys;
- a housing with first spaces for receiving respective ones of the plurality of keys of the keypad, wherein the keys and the first spaces are sized such that there are gaps between the keys and the housing when the keys are received within the first spaces;
- a planar audio speaker located under the keypad, the speaker being co-planar with the keypad, wherein sound projected from the speaker is emitted through the gaps between the keys and the housing;
- and
- a keypad printed circuit board (PCB) operatively coupled with the keypad, wherein the keypad PCB is co-planar with the keypad and the speaker, the speaker is located between the keypad and the keypad PCB, and the keypad has a plurality of holes generally aligned with the gaps.

- a planar audio speaker located under the keypad, the speaker being co-planar with the keypad, wherein sound projected from the speaker is emitted through the gaps between the keys and the housing;
- and
- wherein the speaker includes a flexible printed circuit (FPC) diaphragm and a magnet, and wherein the FPC has a keypad wiring pattern printed on one side thereof that is operatively coupled with the keypad such that the speaker and the keypad are integrated.
An electronic device, comprising:
- a keypad having a plurality of keys;
- a housing with first spaces for receiving respective ones of the plurality of keys of the keypad;
- a keypad printed circuit board (PCB) co-planar to and operatively coupled with the keypad;
- and
- a planar magnet located below the keypad PCB and co-planar to the keypad and the keypad PCB, wherein the keypad PCB includes a speaker coil therein such that the keypad PCB and the magnet form a planar audio speaker, and wherein the keypad PCB includes a polyimide flexible printed circuit diaphragm having the speaker coil printed on one side thereof and a keypad circuit printed on a second, opposing side.
