The present invention relates to a DMB receiver, and more particularly, to a foldable speaker attached to a DMB (Digital Multimedia Broadcasting) receiver that can be freely connected to a computer, a mobile phone, a PDA or the like.

The radio broadcasts currently in use are analogue forms, originally developed for fixed reception, so that the reception of sound while walking or driving a vehicle is considerably degraded and requires high power and a wide frequency band.

In order to solve these problems, the standardization and commercialization of digital audio broadcasting is progressing all over the world, and various methods are used in each country as the digital audio broadcasting standard, and in Korea, the DMB (Digital Multimedia Broadcasting) It is used as a name.

DMB, ie, digital multimedia broadcasting is digitalization of voice broadcasting, so it goes beyond conventional AM and FM radio forms, various data services that can transmit high-quality CD-quality sound, text, graphics and moving image data, two-way, excellent mobile reception quality. It is the next generation broadcast to provide.

Therefore, a DMB receiver for receiving DMB broadcasts is also commercially released.

However, recently released DMB receiver has a problem in that the size of the speaker is limited due to the small size of the portable and can not provide high quality sound.

The present invention has been made to solve the above-described drawbacks, by mounting a speaker that can be folded and extended to the front side of the DMB receiver, it is possible to provide a high-quality sound by the size of the speaker, as well as the DMB receiver An object of the present invention is to provide a DMB receiver having a foldable speaker that can adjust the degree of unfolding of the speaker at a convenient angle when mounted on a vehicle or a table, and protect the LCD screen of the DMB receiver when the speaker is folded.

The present invention for achieving the above object, in the DMB receiver equipped with a foldable speaker, the speaker is rotated around the hinge portion on both sides of the main body of the DMB receiver is installed, is provided with a foldable speaker folded and unfolded to the front side of the main body Provides a DMB receiver.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a DMB receiver equipped with a foldable speaker according to the present invention, Figure 2 is a perspective view of a closed state of the DMB receiver according to the present invention, Figure 3 is a state diagram of the use of the DMB receiver according to the present invention.

As shown in FIG. 1, the DMB receiver includes a main body 10 and a speaker 30 that is rotated at both sides of the main body 10.

The front side of the main body 10 is provided with a liquid crystal screen 12 for viewing the received broadcast, the hinge portion 20 is provided on both sides of the main body 10.

And each hinge portion 20 is provided with a speaker 30 that is electrically connected to the main body 10.

Each speaker 30 corresponds to half the size of the main body 10, and preferably, when the speaker 30 on both sides is closed, the entire front surface of the main body 10 can be covered.

And locking means is provided on one side of each speaker 30, that is, one side facing the hinge portion 20. The locking means has a hook 32 formed on one side of one side of the speaker 30, and the hook groove 34 is formed on one side of the speaker 30 to be fixed when it is closed facing each other.

Referring to the operation of the DMB receiver with a foldable speaker according to the present invention configured as described above are as follows.

As shown in FIG. 2, when the speaker 30 is folded around the hinge portion 20, the entire front surface of the main body 10 is closed to easily carry the LCD screen 12 in a protected state.

At this time, the opposing speaker 30 may be continuously maintained in a closed state by the locking coupling of the hook 32 and the hook groove 34.

In this state, for use of the DMB receiver, as shown in FIG. 3, the speaker 30 from which the hook 32 is separated from the hook groove 34 is unfolded to both sides, and the unfolding degree is a proper angle for smooth mounting. Unfold (30).

Then, the speaker 30 on both sides of the unfolded is closed for carrying or storing again.

As such, it is a very useful invention in which the compact speaker 30 is mounted on the compact DMB receiver to compensate for the sound that can be applied as a disadvantage of the DMB receiver.

What has been described above is only one embodiment for implementing a DMB receiver with a foldable speaker according to the present invention, the present invention is not limited to the above-described embodiment, as claimed in the following claims Without departing from the gist of the invention, anyone of ordinary skill in the art to which the present invention will have the technical spirit of the present invention to the extent that various changes can be made.

As described above, the DMB receiver equipped with the foldable speaker of the present invention can provide a high quality sound by mounting the foldable speaker, as well as the angle of the speaker at a convenient angle when the DMB receiver is mounted on a vehicle or a table. The degree of spreading can be adjusted, and when the speaker is folded, it can protect the LCD screen of the DMB receiver.
