Abstract

An electronic device is disclosed that may include a housing including a first surface facing in a first direction, a second surface facing in a second direction, and a third surface, the first and second direction being generally opposed to one another, the third surface being positioned between the first and second surfaces and being generally orthogonal relative to the first and second directions; at least one speaker arranged in at least a part of the housing; and a speaker enclosure protecting the speaker. The speaker enclosure may include an upper speaker enclosure arranged to face the first surface; and a lower speaker enclosure arranged to face the second surface, and confronting the upper speaker enclosure. Each of the upper and lower speaker enclosures may be at least partially made with magnetic materials that shield a magnetic flux generated in the speaker.

Claims (28)

1. An electronic device comprising:

a housing including a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and a side surface that at least partially surrounds a space between the first surface and the second surface;

a touch screen display between the first surface and the second surface, and at least partially exposed through the first surface; and

at least one speaker arranged in the housing,

wherein the speaker includes a speaker enclosure comprising:

an upper speaker enclosure arranged to face the first surface; and

a lower speaker enclosure arranged to face the second surface, and confronting the upper speaker enclosure,

wherein the upper and lower speaker enclosures are at least partially made with magnetic materials that shield a magnetic flux generated in the speaker,

wherein the magnetic materials compensate a magnetic flux density lost in the speaker enclosure so as to prevent a decrease of a sound pressure generated in the speaker,

wherein the speaker is disposed between the touch screen display and the second surface while aligning to speaker holes formed on the side surface, and

wherein the speaker includes a thin film speaker, the thin film speaker comprising:

a support member coupled to a surface of the lower speaker enclosure facing the upper speaker enclosure between the upper speaker enclosure and the lower speaker enclosure;

an elastic member disposed between the support member and the surface of the low speaker enclosure; and

a speaker core disposed on the support member between the support member and the upper speaker enclosure;

wherein the speaker core includes:

inner and outer magnetic bodies disposed on the support member between the support member and the upper speaker enclosure, wherein the inner magnetic body is surrounded by the outer magnetic body when viewed from above the first surface;

a diaphragm located between the outer magnetic body and the upper speaker enclosure;

a voice coil disposed between the inner magnetic body and the outer magnetic body, vibrating the diaphragm when current is provided to the voice coil; and

a suspension coupled with the diaphragm.

2. The electronic device of claim 1 , wherein the at least one speaker comprises a first speaker and a second speaker that are arranged approximately symmetrically relative to a home key of the electronic device when viewed from a front of the electronic device,

wherein the speaker holes includes first speaker holes aligned to the first speaker and second speaker holes aligned to the second speaker.

3. The electronic device of claim 2 , wherein the first speaker and the second speaker are arranged side by side, without overlapping with each other.

4. The electronic device of claim 1 , further comprising:

an internal support structure disposed between the at least one speaker and the touch screen display, and at least partially comprising metallic materials.

5. The electronic device of claim 4 , wherein at least part of the housing includes a magnetic material, and the lower speaker enclosure is mounted on the at least part of the housing including the magnetic material.

6. The electronic device of claim 1 , wherein the respective upper and lower speaker enclosures are configured to have the same thickness.

7. The electronic device of claim 1 , wherein the respective upper and lower speaker enclosures are configured to have different thicknesses.

8. The electronic device of claim 1 , wherein the touch screen display includes a digitizer for receiving an input by an electronic pen.
