Abstract

An electronic device may include a housing, a first frame disposed inside the housing and including a first surface, a second frame forming an internal space by being coupled with the first frame, and including a second surface opposed to the first surface, a speaker disposed in the internal space and including at least one voice coil, and a battery disposed on a side of the second frame. The second frame may include at least one frame hole, and a ratio μ/μ0 of a magnetic permeability to a vacuum permeability of at least one of a material of the first frame or a material of the second frame may be equal to or greater than 1000.

First claim

The invention claimed is:

1 . An electronic device including:
a housing defining a first internal space; a first frame disposed at least partially inside the first internal space of the housing and including a first surface; a second frame including a second surface opposed to the first surface, wherein the first frame and the second frame form a second internal space between the first and second surfaces and at least partially inside the first internal space; a speaker disposed in the second internal space and including at least one voice coil; and a battery disposed on a side of the second frame, wherein the second frame includes at least one frame hole, and wherein a ratio μ/μ0 of a magnetic permeability to a vacuum permeability of at least one of a material of the first frame or a material of the second frame is at least 1000.

2 . The electronic device of claim 1 , wherein the voice coil includes a first voice coil and a second voice coil, and the second voice coil is disposed adjacent to the second frame.

3 . The electronic device of claim 1 , wherein an outer surface of the second frame contacts an inner surface of the first frame.

4 . The electronic device of claim 1 , wherein an inner surface of the second frame contacts an outer surface of the first frame.

5 . The electronic device of claim 1 , wherein the frame hole is formed at least partially in the second surface.

6 . The electronic device of claim 1 , wherein the frame hole is a side frame hole formed at least partially in a side surface of the second frame.

7 . The electronic device of claim 1 , wherein a central axis of the battery coincides with a central axis of the speaker.

8 . The electronic device of claim 1 , wherein a central axis of the battery is spaced apart from a central axis of the speaker.

9 . The electronic device of claim 1 , further including a winding disposed adjacent to the battery.

10 . The electronic device of claim 1 , further including a mesh disposed on the frame hole.

11 . An electronic device including:
a housing defining a first internal space; a first frame disposed at least partially inside the first internal space of the housing and including a first surface; a second frame including a second surface opposed to the first surface, wherein the first frame and the second frame form a second internal space between the first and second surfaces and at least partially inside the first internal space; a speaker disposed in the second internal space and including a first voice coil and a second voice coil; and a battery disposed on a side of the second frame, wherein the second frame includes at least one frame hole, and wherein a ratio μ/μ0 of a magnetic permeability to a vacuum permeability of at least one of a material of the first frame or a material of the second frame is at least 1000.

12 . The electronic device of claim 11 , wherein an outer surface of the second frame contacts an inner surface of the first frame.

13 . The electronic device of claim 11 , wherein an inner surface of the second frame contacts an outer surface of the first frame.

14 . The electronic device of claim 11 , wherein the frame hole is at least partially formed in the second surface.

15 . The electronic device of claim 11 , wherein the frame hole is a side frame hole at least partially formed in a side surface of the second frame.

16 . The electronic device of claim 11 , wherein a central axis of the battery coincides with a central axis of the speaker.

17 . The electronic device of claim 11 , wherein a central axis of the battery is spaced apart from a central axis of the speaker.

18 . The electronic device of claim 11 , further including a winding disposed adjacent to the battery.

19 . The electronic device of claim 11 , further including a mesh disposed on the frame hole.

20 . The electronic device of claim 11 , further including an adhesive member comprising adhesive material and a protection member disposed on the second frame.
