5. The receiver of claim 1 wherein the projection unit includes an inner space disposed between the receiver hole and the inner space of the casing.
6. The receiver of claim 1 wherein the receiver hole comprises a plurality of holes.
7. The receiver of claim 1 , further comprising a tele-coil (T-coil) disposed in the projection unit adjacent the receiver hole.
8. The receiver of claim 1 wherein the audio path comprises a non-linear path.
9. The receiver of claim 1 wherein the diaphragm is disposed between the diaphragm driving unit and the inner space, and the audio path extends from the diaphragm central region through the inner space to the receiver hole.
10. A mobile terminal comprising:
a receiver including:
a casing including walls and an inner space defined at least partially by the walls,
a diaphragm driving unit disposed in the casing,
a diaphragm including a central region disposed in the casing,
a projection unit extending from the casing, the projection unit including walls and a receiver hole disposed in one of the walls, and
an audio path defined within the casing walls and the projection unit walls; and
a Printed Circuit Board (PCB) including a cutout along an edge;
wherein the receiver is disposed in the cutout in the PCB.
11. The mobile terminal of claim 10 , further comprising:
a display module; and
a glass plate,
wherein the display module is disposed between the glass plate and the PCB, and the projection unit of the receiver disposed on the PCB extends beyond an edge of the display module.
12. The mobile terminal of claim 11 wherein the glass plate includes a hole that aligns with the receiver hole.
13. The mobile terminal of claim 11 wherein the receiver hole comprises a plurality of receiver holes and the glass plate includes a cutout that aligns with a length of the plurality of receiver holes.
14. The mobile terminal of claim 10 wherein the receiver further comprises a guide groove disposed on an outer wall of the casing, and the cutout in the PCB is slid into the guide groove of the receiver.
15. The mobile terminal of claim 14 wherein the receiver further comprises an electrical contact disposed in the guide groove, and the PCB comprises an electrical contact point that contacts the electrical contact when the PCB is disposed in the guide groove of the receiver.
16. The mobile terminal of claim 10 wherein the receiver further comprises a tele-coil (T-coil) disposed in the projection unit adjacent to the receiver hole.
17. The mobile terminal of claim 10 wherein the PCB comprises a plurality of PCBs each including a cutout and the receiver comprises a plurality of guide grooves disposed on an outer wall of the casing, and each cutout in the plurality of PCBs is slid into a corresponding guide groove of the plurality of guide grooves.
18. The mobile terminal of claim 10 wherein the diaphragm is disposed between the diaphragm driving unit and the inner space, and the audio path extends from the diaphragm central region through the inner space to the receiver hole.
19. A method for disposing a receiver in a mobile terminal, the method comprising:
providing a receiver including:
a casing including walls and an inner space defined at least partially by the walls,
a diaphragm driving unit disposed in the casing,
a diaphragm including a central region disposed in the casing,
a projection unit extending from the casing, the projection unit including walls and a receiver hole disposed in one of the walls, and
an audio path defined within the casing walls and the projection unit walls,
wherein the diaphragm is disposed between the diaphragm driving unit and the inner space, and the audio path extends from the diaphragm central region through the inner space to the receiver hole; and
providing a Printed Circuit Board (PCB) including a cutout along an edge; and
disposing the receiver into the cutout on the PCB.
20. The method of claim 19 , further comprising:
providing a display module; and
providing a glass plate;
wherein the display module is disposed between the glass plate and the PCB, and the projection unit of the receiver extends over the display module.
21. The method of claim 20 , wherein the glass plate includes a hole, and the method further comprises aligning the glass plate hole with the receiver hole.
22. The method of claim 20 wherein the receiver further comprises a guide groove disposed on an outer wall of the casing, and the method further comprises sliding the cutout in the PCB into the guide groove of the receiver.
