Abstract

An electronic device includes a speaker module which includes a speaker unit and a first speaker housing that is coupled to the speaker unit in a first direction. The first speaker housing accommodates the speaker unit, and is arranged in the inner space of the electronic device. A soundproof device allows the inner space of the electronic device to communicate with the outside, and an acoustic passage connects the soundproof device and a portion from which a sound is radiated by the speaker unit of the speaker module. The speaker module can further include an airtight member for sealing a gap between the speaker module and the acoustic passage so that the sound radiated from the speaker unit is transmitted to the acoustic passage.

First claim

1 . An electronic device comprising:
a speaker module including a speaker unit and a first speaker housing coupled to the speaker unit in a first direction, the speaker module accommodating the speaker unit and disposed in an inner space of the electronic device; a soundproof device connecting the inner space of the electronic device with an outside area external to the electronic device; and an acoustic passage connecting the soundproof device and a portion from which a sound is radiated from the speaker unit of the speaker module, wherein the speaker module further includes an airtight member which seals a gap between the speaker module and the acoustic passage so that the sound radiated from the speaker unit is transmitted to the acoustic passage.

2 . The electronic device of claim 1 , wherein the airtight member of the speaker module is disposed in the first speaker housing.

3 . The electronic device of claim 1 , wherein the speaker module comprises further a conduit member forming the acoustic passage, and the airtight member of the speaker module is disposed on the conduit member.

4 . The electronic device of claim 1 , wherein the speaker module comprises further a second speaker housing coupled to the first speaker housing in the first direction and a resonance space formed by the first speaker housing and the second speaker housing.

5 . The electronic device of claim 4 , wherein at least one electronic component is disposed in the second speaker housing of the speaker module.

6 . The electronic device of claim 4 , wherein an antenna of the electronic device is disposed in the second speaker housing of the speaker module.

7 . The electronic device of claim 1 , wherein the airtight member of the speaker module comprises:
an airtight frame corresponding to an outer periphery of the speaker unit and disposed in the speaker unit; and an airtight part disposed in the airtight frame to seal a gap between the airtight frame and the acoustic passage, the airtight part formed of a material having an elastic force.

8 . The electronic device of claim 1 , wherein the speaker unit of the speaker module comprises:
a unit frame; a diaphragm at least partially fixed to the unit frame; a voice coil coupled to the diaphragm; a magnet disposed adjacent to the voice coil; and a yoke accommodating the magnet.

9 . The electronic device of claim 8 , wherein the yoke of the speaker unit of the speaker module comprises:
a first yoke part having a first thickness; and a second yoke part having a second thickness smaller than the first thickness of the first yoke part, wherein at least a portion of the first speaker housing of the speaker module is disposed on the second yoke part of the yoke of the speaker unit.

10 . The electronic device of claim 8 , wherein at least a portion of the first speaker housing of the speaker module is disposed on the unit frame of the speaker unit.

11 . The electronic device of claim 8 , wherein at least a portion of the first speaker housing of the speaker module is disposed on the magnet of the speaker unit, at least a portion of which protrudes toward an outer surface of the speaker unit.

12 . A speaker module comprising:
a speaker unit;
a first speaker housing coupled to the speaker unit in a first direction and accommodating the speaker unit; and
an airtight member sealing an acoustic passage connecting the speaker unit and a portion of the speaker unit from which a sound is radiated.

13 . The speaker module of claim 12 , wherein the airtight member comprises an airtight frame formed to correspond to an outer periphery of the speaker unit and disposed on the speaker unit.

14 . The speaker module of claim 12 , wherein the airtight member is disposed in the first speaker housing.

15 . The speaker module of claim 12 , further comprising a conduit member forming the acoustic passage, wherein the airtight member is disposed on the conduit member.

16 . An electronic device comprising:
a speaker housing defining an acoustic passage configured to radiate sound; a speaker unit disposed in the speaker housing and configured to output sound; an acoustic passage extending from the speaker unit to radiate the sound output from the speaker unit; an airtight member interposed disposed on the speaker unit and defining a gap between the airtight member and the speaker housing; an airtight part on the airtight member and sealing the gap so that the sound output from the speaker unit is directed to the acoustic passage.

17 . The electronic device of claim 16 , wherein the airtight member includes a single airtight frame having an opening configured to radiate the sound therethrough and towards the acoustic passage.

18 . The electronic device of claim 16 , wherein the airtight member includes:
a first airtight frame accommodating an outer periphery of the speaker unit; and a second airtight frame coupled in the first airtight frame portion, each of the first and second airtight frames having an opening configured to radiate the sound therethrough and towards the acoustic passage.

19 . The electronic device of claim 16 , wherein one or both of the airtight part and the airtight member is formed from an elastomer material.

20 . The electronic device of claim 16 , further comprising:
a display module covering the speaker housing; and a soundproof hole between the speaker housing and the display module to provide access to an outside area external from the electronic device.
