Field of the Invention The present invention relates to a television combined refrigerator having a television installed at a freezer door or a refrigerator compartment door, and more particularly, to an acoustic device of a television combined refrigerator capable of improving sound quality by improving performance of a speaker for transmitting sound.

In general, a refrigerator is mainly formed of a top mount type refrigerator, in which a freezer compartment and a refrigerating compartment are formed up and down, and a freezer door and a refrigerating compartment door can be opened and closed in the freezer compartment and the refrigerating compartment, respectively. Accordingly, many side by side type refrigerators are formed on both sides of the freezer compartment and the refrigerating compartment, and the freezer compartment door and the refrigerating compartment door are configured to be opened and closed with both end portions pivoted.

Recently, side-by-side refrigerators are not only to satisfy various needs of the user, but also to prevent cold air loss. An ice extractor capable of extracting cold water or ice is integrally formed on the freezer door side. The home bar is formed so that the stored beverage or water can be easily taken out even if the refrigerator door is not opened or closed.

However, the side-by-side refrigerator as described above requires a relatively large installation space in a limited residential space because the product is made large as the capacity of the freezer compartment and the refrigerating compartment is large.

However, in recent years, as the kitchen and living room are used as one space, as the side-by-side refrigerator is installed in the kitchen and living room, the actual living space that the user can use decreases as well. The installation space of electronic products is also reduced.

Therefore, the conventional refrigerator can not only control the installation space with other electronic products as the capacity increases, but also need to be manufactured integrally with other electronic products in order to satisfy various needs of consumers. Is being developed.

By the way, the television combined refrigerator as described above is configured to include a speaker to transmit sound as the television is integrally formed on the freezer door or the refrigerating compartment door side, and the sound generated simply in front of the speaker is transferred to the outside through the speaker hole. Since the sound generated to the rear of the speaker is directly reflected to the adjacent freezer door or the refrigerator door side is diffusely reflected, not only the bass sound is hardly heard but also the high sound is emphasized and torn.

The present invention has been made to solve the problems of the prior art, it is an object of the present invention to provide a sound system of a refrigerator for a television combined to improve the sound quality by installing a separate component around the speaker.

According to an aspect of the present invention, there is provided a sound system of a television combined refrigerator according to the present invention, a monitor mounted on a side of a freezer compartment or a refrigerator compartment door, a mounting panel mounted around the monitor, and including a speaker hole and an operation button, and the mounting panel.

A freezer compartment door 4 and a refrigerator compartment door 14 are installed on the front of the main body 2 and the refrigerating compartment main body 12 so as to be openable and closed, and an ice extraction device 10 is provided on the front of the freezer compartment door 4 so that the user can If you press the container such as a cup without opening and closing the freezer door 4, the ice or cold water can be easily taken out, and the front of the refrigerator compartment door 14 is provided with a television (Television: 20) integrally The television 20 can be easily watched even in a space where a refrigerator is easily installed.

Of course, a plurality of shelves 6 and 16 are installed in multiple stages inside the freezing compartment body 2 and the refrigerating compartment body 12, and a plurality of door baskets 8 are inside the freezing compartment door 4 and the refrigerating compartment door 14. , 18) is detachably installed so that storage items including various foods and the like can be placed therein.

Here, the television 20 preferably uses a thin LCD monitor 22 to prevent excessive projection from the refrigerating compartment door 14 as shown in FIG. 3, and the LCD monitor 22. The speaker panel (24a, 24b, 24c) is formed around the periphery so that the sound can be transmitted to the outside, and the mounting panel (24) equipped with the operation button (24d) so that the user can directly adjust the channel and volume, etc. Is installed.

In addition, a speaker 26 is installed on the rear surface of the speaker holes 24a, 24b, and 24c of the mounting panel to transmit sound by transforming an electric signal into sound waves, and the mounting panel is provided on the back of the operation button 24d of the mounting panel. A controller (not shown) is installed to be connected to the operation button 24d of the LCD monitor 22 and the speaker 26 to control the operation of the LCD monitor 22 and the speaker 26.

In this case, the television 20 may be installed on the freezing compartment door 4 side, and even if the television 20 is mounted on the refrigerating compartment door 14 side, a separate decorative panel 28 may not be exposed to the exterior. ) May be installed around the television 20.

Specifically, the mounting panel 24 is installed so as to be positioned around the LCD monitor 22, the plurality of speaker holes 24a so as to be concentrated on the center side to the mounting panel 24 installed to cover the speaker 26 , 24b and 24c are formed, and the speaker holes 24a, 24b and 24c of the mounting panel surround the speaker 26 while having a predetermined space with the speaker 26 as shown in FIG. 4. The rectangular box-shaped ring 32 is installed so that the sound generated from the front of the speaker 26 and the sound generated from the back of the speaker 26 are reflected to improve the bass.

In addition, a predetermined length is installed at one side of the ring barrel 32 so as to communicate with the speaker holes 24a, 24b, and 24c of the mounting panel so that the sound generated on the rear surface of the speaker 26 is reflected and transmitted to the outside. It is configured to further include a delivery pipe 34 of the sound through the delivery pipe 34 so that the sound is transmitted to the outside because the sound pressure is transmitted to the outside while passing through the delivery pipe 34 is greater. .

On the other hand, the sound absorbing material (36) is installed on the inner surface of the ring barrel 32 so as to absorb high sound on the surface opposite to the rear surface of the speaker 26, the sound absorbing material (36) has a plurality of fine holes on the surface or inside It is preferable that a kind of cloth is used as the formed porous sound absorbing material, and the sound absorbing material 36 improves the sound quality by allowing the high sound of the sound generated from the speaker 26 to hit inside a minute hole to be consumed by thermal energy.

As described above, when the television 20 mounted on the freezer compartment door 4 or the refrigerating compartment door 14 side is turned on in the refrigerator, sound is transmitted to the outside through the speaker 26, specifically, the speaker 26. The sound generated from the front of the) is directly transmitted to the outside through the speaker holes 24a, 24b, and 24c of the mounting panel, while the sound generated from the rear surface of the speaker 26 is reflected by the ringing cylinder 32. As the sound pressure is increased while passing through the delivery pipe 34, the sound may be transmitted farther to the outside, and the sound may be improved to be louder.

In addition, the high sound of the sound generated on the rear surface of the speaker 26 is bumped and rubbing inside the minute hole of the sound absorbing material 36, so that the sound energy is converted into heat energy and is consumed, thereby preventing the high sound from being torn off. Can improve the treble.

Therefore, as shown in FIG. 5, the sound generated from the speaker that does not include the ring according to the prior art is not easily heard by the user because the pitch of the bass is low, and the pitch of the high pitch is high in some frequency bands, so as to be torn by the user.
