Abstract

An electronic device is disclosed. The electronic device includes a housing, a display, at least one through-hole, a speaker module, and an internal structure. The housing includes a front plate, a rear plate, and a side member. The display and the speaker module are disposed between the front plate and the rear plate. The through-hole is formed through the front plate between a portion of the side member and the display. The speaker module includes an acoustic generation surface facing the front plate near the through-hole. The internal structure is disposed between the front plate and the acoustic generation surface. The internal structure and the acoustic generation surface form a space, acoustically connected to the through-hole. The internal structure includes a surface facing the acoustic generation surface. The surface of the internal structure includes a plurality of areas, each with a different clearance from the acoustic generation surface.

First claim

What is claimed is:

1 . An electronic device, comprising:
a housing configured to include a front plate, a rear plate facing a direction opposite to the front plate, and a side member that surrounds a space between the front plate and the rear plate; a touch screen display configured to be disposed between the front plate and the rear plate; at least one through-hole configured to, when seen from the front plate, be formed through the front plate between a portion of the side member and the touch screen display; a speaker module configured to be disposed between the front plate and the rear plate and, when seen from the front plate, include an acoustic generation surface facing the front plate, near the through-hole; and an internal structure configured to be disposed between the front plate and the acoustic generation surface, wherein the internal structure and the acoustic generation surface form a space, acoustically connected to the through-hole, together, wherein the internal structure comprises a surface facing the acoustic generation surface, and wherein the surface of the internal structure comprises a plurality of areas, each of the plurality of areas includes a different clearance.

2 . The electronic device of claim 1 , wherein the acoustic generation surface is substantially flat, and
wherein the plurality of areas comprise: a first area including a first clearance from the acoustic generation surface; and a second area including a second clearance greater than the first clearance from the acoustic generation surface.

3 . The electronic device of claim 2 , wherein the plurality of areas further comprise:
a third area including the second clearance from the acoustic generation surface, wherein, when seen from the front plate, the first area is disposed between the second area and the third area, and wherein the first area, second area, and third area are extended substantially parallel to each other in a direction facing the portion of the side member from the touch screen display.

4 . The electronic device of claim 3 , wherein the second clearance increases in a direction.

5 . The electronic device of claim 4 , wherein the first area is substantially parallel to the acoustic generation surface.

6 . The electronic device of claim 1 , wherein, when seen from the front plate, the acoustic generation surface overlaps at least in part with the touch screen display.

7 . The electronic device of claim 6 , wherein the internal structure is at least in part disposed between the touch screen display and the acoustic generation surface.

8 . An electronic device, comprising:
a housing configured to include a front plate disposed to face a first direction, a rear plate facing a second direction opposite to the first direction, and a side member that surrounds a space between the front plate and the rear plate; a display configured to face the first direction and be disposed between the front plate and the rear plate; a supporting member configured to be disposed between the display and the rear plate; a speaker module configured to include an acoustic generation surface, capable of outputting an acoustic signal, facing the first direction; and a waterproof member configured to be disposed between a portion of the supporting member and the acoustic generation surface, wherein the front plate comprises a through-hole configured to face the first direction and be acoustically connected with the acoustic generation surface, wherein the supporting member comprises a speaker module receiving part configured to include a surface facing the speaker module in an area adjacent to the through-hole, the speaker module receiving part in which the speaker module is received; and wherein the surface of the speaker module receiving part comprises a rib protruded to the acoustic generation surface.

9 . The electronic device of claim 8 , wherein the rib is extended in a direction perpendicular to a direction where the through-hole is extended.

10 . The electronic device of claim 9 , wherein the rib gradually increases in width, as distance between the rib and the through-hole increase.

11 . The electronic device of claim 8 , wherein a surface of the rib is substantially parallel to the acoustic generation surface.

12 . The electronic device of claim 8 , wherein the rib includes a rounded edge portion that is adjacent to the acoustic generation surface.

13 . The electronic device of claim 8 , wherein the surface of the speaker module receiving part is closer to the acoustic generation surface as distance between the speaker module receiving part and the through-hole increase.

14 . The electronic device of claim 8 , wherein the rib is integrally formed of the same material as the speaker module receiving part.

15 . An electronic device, comprising:
a housing configured to include a front plate disposed to face a first direction, a rear plate facing a direction opposite to the first direction, and a side member that surrounds a space between the front plate and the rear plate; a display configured to face the first direction and be disposed between the front plate and the rear plate; a supporting member configured to be disposed between the display and the rear plate; a speaker module configured to include an acoustic generation surface, capable of outputting an acoustic signal, facing the first direction; and a waterproof member configured to be disposed between a portion of the supporting member and the acoustic generation surface, wherein the front plate comprises a through-hole configured to face the first direction and be acoustically connected with the acoustic generation surface, wherein the supporting member comprises a speaker module receiving part configured to include a surface facing the speaker module in an area adjacent to the through-hole, the speaker module is received in the speaker module receiving part; and wherein the surface of the speaker module receiving part comprises a plurality of areas, each of the plurality of areas includes a different clearance from the acoustic generation surface.

16 . The electronic device of claim 15 , wherein the plurality of areas comprise:
a first area including a first clearance from the acoustic generation surface; and a second area including a second clearance greater than the first clearance from the acoustic generation surface.

17 . The electronic device of claim 16 , wherein the first area is an area corresponding to the center of the acoustic generation surface.

18 . The electronic device of claim 16 , wherein the first area is substantially parallel to the acoustic generation surface.

19 . The electronic device of claim 16 , wherein, the second area is closer to the acoustic generation surface as distance between the second area and the through-hole increase.

20 . The electronic device of claim 16 , wherein the second area receives liquid material introduced through the through-hole.
