Abstract

An electronic device is provided. The electronic device includes a housing including a front plate, a rear plate, and a lateral member surrounding a space between the front and rear plates and having at least one through-hole. The electronic device further includes a display disposed to be seen through the front plate, and a speaker structure disposed near the through-hole in the space between the display and the rear plate. The speaker structure includes a yoke disposed between the display and the rear plate and facing the display, a diaphragm disposed between the rear plate and the yoke and spaced apart from the rear plate, a magnet disposed between the yoke and the diaphragm, a speaker housing surrounding, at least in part, at least one of the diaphragm, the yoke, or the magnet and including a first opening formed toward the rear plate and a second opening formed toward the through-hole. The electronic device further includes a sealing member disposed between the speaker housing and the rear plate and surrounding the first opening when viewed from the rear plate. A sound conduit includes, between the diaphragm and the through-hole, a first space formed by the first opening, the rear plate, and the sealing member, and a second space connected to the first space through the second opening.

First claim

What is claimed is:

1. An electronic device comprising:
a housing comprising:
a front plate facing a first direction,
a rear plate facing a second direction opposite to the first direction, and
a lateral member surrounding a space between the front plate and the rear plate, the lateral member having at least one through-hole;

a display disposed to be viewed through the front plate;
an intermediate plate disposed between the display and the rear plate; and
a speaker structure disposed adjacent to the at least one through-hole in the space,
wherein the speaker structure comprises:
a yoke disposed between the intermediate plate and the rear plate, the yoke facing the rear plate,
a diaphragm disposed between the intermediate plate and the yoke, the diaphragm being spaced apart from the intermediate plate,
a magnet disposed between the yoke and the diaphragm,
a speaker housing surrounding, at least in part, at least one of the diaphragm, the yoke, or the magnet, the speaker housing including a first opening formed toward the intermediate plate, a recess formed as a thin stepped portion at a part of the speaker housing, and a second opening formed toward the at least one through-hole, and
a sealing member disposed in the recess between the speaker housing and the intermediate plate, the sealing member surrounding the first opening when viewed from the intermediate plate, and

wherein a sound conduit includes, between the diaphragm and the at least one through-hole, a first space formed by the first opening, the intermediate plate along a rim of the first opening, and the sealing member, and a second space connected to the first space through the second opening.

2. The electronic device of claim 1 , wherein the first opening is in sound communication with the second opening and the diaphragm.

3. The electronic device of claim 1 , wherein the sealing member is formed of at least one of rubber, urethane, or silicone.

4. The electronic device of claim 1 , wherein the sealing member is attached to the recess.

5. The electronic device of claim 1 , wherein the first opening is disposed at a position overlapped with the diaphragm when the front plate is viewed from above.

6. The electronic device of claim 1 , wherein a distance between the diaphragm and the intermediate plate through the first opening is determined by a maximum vibration width of the diaphragm.

7. An electronic device comprising:
a housing comprising:
a front plate facing a first direction,
a rear plate facing a second direction opposite to the first direction, and
a lateral member surrounding a space between the front plate and the rear plate, the lateral member having at least one through-hole;

a display disposed to be viewed through the front plate;
an intermediate plate disposed between the display and the rear plate;
a structure disposed between the front plate and the rear plate;
an acoustic device disposed adjacent to the at least one through-hole in the space, the acoustic device comprising:
an acoustic device housing disposed in the space and including a first opening and a second opening, the first opening being formed toward the intermediate plate, a recess formed as a thin stepped portion at a part of the acoustic device housing, and the second opening being formed toward the at least one through-hole, the second opening being in sound communication with the first opening,
a diaphragm disposed to be exposed, at least in part, toward the structure through the first opening in the acoustic device housing,
at least one magnet disposed adjacent to the diaphragm, and
at least one yoke disposed to be at least partially in contact with the at least one magnet; and

a sealing member disposed in the recess between the acoustic device housing and the intermediate plates along a rim of the first opening,
wherein a sound conduit comprises:
a first space formed by the first opening, the structure, and the sealing member, and
a second space connected to the first space through the second opening.

8. The electronic device of claim 7 , wherein the acoustic device comprises at least one of a speaker or a microphone.

9. The electronic device of claim 7 , wherein a distance between the diaphragm and the structure through the first opening is determined by a maximum vibration width of the diaphragm.
