Abstract

A refrigerator is provided. The refrigerator includes a main body, a storage compartment, a door configured to open and close the storage compartment, and a speaker device embedded in the door, wherein the door includes upper door and lower door, wherein the speaker device includes at least one first speaker facing a first direction that is a user handle space direction, and configured to output sound in a full-range frequency band, and at least one second speaker facing a second direction that is a door inner wall surface direction as a direction different from the first direction, and configured to output sound in a full-range frequency band.

First claim

What is claimed is:

1 . A refrigerator comprising:
a main body; a storage compartment; a door configured to open and close the storage compartment; and a speaker device embedded in the door, wherein the door comprises:
an upper door, and
a lower door, and
wherein the speaker device comprises:
at least one first speaker facing a first direction that is a user handle space direction, and configured to output sound in a full-range frequency band, and
at least one second speaker facing a second direction that is a door inner wall surface direction as a direction different from the first direction, and configured to output sound in a full-range frequency band.

2 . The refrigerator of claim 1 , further comprising:
a passive radiator arranged at an opposite side to the at least one second speaker and facing a third direction opposite to the second direction.

3 . The refrigerator of claim 2 ,
wherein the speaker device is installed inside the upper door, wherein the first direction is a direction from the upper door to the lower door, wherein the second direction is a direction toward a front side of the refrigerator in the upper door, and wherein the third direction is a direction toward a rear side of the refrigerator.

4 . The refrigerator of claim 1 ,
wherein the speaker device is embedded in a vertical direction of the upper door, and wherein the speaker device has a first certain space in the second direction between the at least one second speaker and an inside wall surface of the upper door of the refrigerator.

5 . The refrigerator of claim 4 , wherein a width of the first certain space differs in the vertical direction of the upper door.

6 . The refrigerator of claim 4 , wherein a width of the first certain space increases downward in the vertical direction of the upper door.

7 . The refrigerator of claim 3 ,
wherein a second certain space is provided in the third direction between the passive radiator and an inner wall surface of the upper door, and wherein a width of the second certain space increases downward in a vertical direction of the upper door.

8 . The refrigerator of claim 1 , wherein the at least one first speaker is exposed in a direction from the upper door of the refrigerator toward the lower door.

9 . The refrigerator of claim 1 , further comprising:
a grill covering a front side of the at least one first speaker.

10 . A refrigerator comprising:
a main body; a storage compartment; a door configured to open and close the storage compartment; and a speaker device embedded in the door, wherein the door comprises:
an upper door, and
a lower door, and
wherein the speaker device comprises:
at least one first speaker configured to output high-band sound, facing a first direction that is a direction toward a handle of the door,
at least one second speaker configured to output low-band sound, facing a second direction that is a direction toward an inner wall surface of the door, and
a passive radiator in a rear side of the second speaker, facing a third direction that is opposite to the second direction.

11 . The refrigerator of claim 10 ,
wherein the speaker device is installed inside the upper door, wherein the first direction is a direction from the upper door to the lower door, wherein the second direction is a direction toward a front side of the refrigerator in the upper door, and wherein the third direction is a direction toward a rear side of the refrigerator.

12 . The refrigerator of claim 10 ,
wherein the speaker device is embedded in a vertical direction of the upper door, and wherein the speaker device has a first certain space in the second direction between the at least one second speaker and an inside wall surface of the upper door.

13 . The refrigerator of claim 12 , wherein a width of the first certain space between the at least one second speaker and an inner wall surface of the upper door increases downward in the vertical direction of the upper door.

14 . The refrigerator of claim 13 ,
wherein a second certain space is provided in the third direction between the passive radiator and an inner wall surface of the upper door, and wherein a width of the second certain space increases downward in the vertical direction of the upper door.

15 . The refrigerator of claim 10 , wherein the at least one first speaker is exposed in a direction from the upper door toward the lower door.
