Abstract

The present disclosure relates to an electronic device having a side acoustic emission speaker. The electronic device may include a speaker module accommodated in the electronic device. The speaker module may include a first substrate, a speaker having a lower surface formed on the first substrate, a waterproof member contacting at least one part of an upper surface and at least one part of a first side surface of the speaker, and a second substrate contacting a second side surface of the speaker and overlapping the upper surface of the speaker. The second substrate may include a first subarea displaced from the upper surface of the speaker by a first distance and having a first thickness and a second subarea displaced from the upper surface of the speaker by a second distance and having a second thickness. A space disposed between the waterproof member and the first subarea may include an acoustic emission hole configured to transfer a sound emitted by the speaker to the outside of the electronic device.

First claim

What is claimed is:

1. An electronic device comprising:
a speaker module disposed in the electronic device;
wherein the speaker module comprises:
a first substrate,
a speaker including a lower surface disposed on the first substrate,
a waterproof member contacting at least one part of an upper surface of the speaker and at least one part of a first side surface of the speaker, and
a second substrate contacting a second side surface of the speaker and overlapping an upper surface of the speaker;
wherein the second substrate comprises a first subarea spaced apart from the upper surface of the speaker by a first distance, the first subarea having a first thickness, and a second subarea spaced apart from the upper surface of the speaker by a second distance, the second subarea having a second thickness;
wherein a space between the waterproof member and the first subarea includes an acoustic emission hole configured to transfer a sound emitted by the speaker to the outside of the electronic device, and
wherein the first thickness is less than or equal to the second thickness.

2. The electronic device of claim 1 , wherein the first subarea corresponds to an end of the waterproof member covering a part of the upper surface of the speaker, and to a conduit area between a sound path and a sound reflection space located on the upper surface of the speaker; and the second subarea corresponds to the inside of the sound reflection space.

3. The electronic device of claim 1 , wherein the first distance is greater than or equal to the second distance.

4. The electronic device of claim 1 , wherein the first and second subareas of the second substrate comprise different materials from each other.

5. The electronic device of claim 4 , wherein the first subarea comprises a metallic material and the second subarea comprises a plastic extrusion material.

6. The electronic device of claim 1 , wherein the second substrate comprises at least one groove in the second subarea.

7. The electronic device of claim 6 , wherein the groove is located at the rear surface portion of the second subarea facing the upper surface of the speaker.

8. The electronic device of claim 6 , wherein the groove comprises a plurality of grooves arranged in substantially a center area of the second subarea excluding a peripheral border portion of the second subarea.

9. The electronic device of claim 1 , wherein the second subarea facing the upper surface of the speaker has a greater area than an area of the first subarea facing the upper surface of the speaker.

10. An electronic device comprising:
a speaker module accommodated in the electronic device;
wherein the speaker module comprises:
a speaker,
an enclosure case configured to surround at least one part of the speaker, and
a waterproof member disposed in the enclosure case and disposed to cover a side surface and a part of an upper surface of the speaker;
wherein an upper substrate of the enclosure case facing the upper surface of the speaker includes at least two subareas, each subarea having a different thickness,.
wherein the enclosure case comprises:
a first substrate configured to accommodate at least one part of the speaker, and
a second substrate of which at least one side surface extends from a side surface of the first substrate, at least a portion of the second substrate corresponding to an upper surface of the speaker;
wherein the second substrate comprises a first subarea spaced apart from the upper surface of the speaker by a first distance, the first subarea having a first thickness, and a second subarea spaced apart from the upper surface of the speaker by a second distance, the second subarea having a second thickness;

wherein a space between the waterproof member and the first subarea includes an acoustic emission hole configured to transfer a sound emitted by the speaker to outside of the electronic device, and
wherein the first thickness is less than or equal to the second thickness.

11. The electronic device of claim 10 , wherein the first subarea corresponds to an end of the waterproof member covering a part of the upper surface of the speaker, and to a conduit area between a sound path and a sound reflection space located on the upper surface of the speaker; and the second subarea corresponds to the inside of the sound reflection space.

12. The electronic device of claim 10 , wherein the first distance is greater than or equal to the second distance.

13. The electronic device of claim 10 , wherein the first and second subareas of the second substrate comprise different materials from each other.

14. The electronic device of claim 13 , wherein the first subarea comprises a metallic material and the second subarea comprises a plastic extrusion material.

15. The electronic device of claim 10 , wherein the second substrate comprises at least one groove in the second subarea.

16. The electronic device of claim 15 , wherein the groove is located at a rear surface portion of the second subarea facing the upper surface of the speaker.

17. The electronic device of claim 15 , wherein the groove comprises a plurality of grooves arranged in substantially a center area of the second subarea excluding a peripheral border portion of the second subarea.
