Connectors 13 for connection are respectively provided. The coupling means includes a plurality of coupling grooves 14 and coupling hooks 15 and the like.

In addition, one side of the front speaker 30, the upper case (30a) is connected to the front speaker 30 is provided with a tweeter (tweeter 33) for reproducing high-pitched sound.

As shown in FIG. 4, an integrated connector 41 is installed at the lower end of the lower case 10a to simultaneously apply power to the subwoofer 11, the front speaker 30, and the rear speaker 20. do.

In addition, a lower sound output port 12 for outputting low sound is formed in the lower front portion of the lower case 10a, and a support plate for supporting the case 10 and having a sense of stability at the bottom of the lower case 10a ( 40) is installed.

And the direction of the negative radiation axis of the rear speaker 20 is provided on the side inclined at about 30 ° to 60 ° from the horizontal plane with respect to the direction of the negative radiation axis of the front speaker 30. That is, as shown in Figure 6, the rear speaker 20 is installed with an inclination angle (α) of about 30 ° to 60 ° from the front of the upper case (30a).

On the other hand, reference numerals 21 and 31, which are not described in the drawings, indicate jersey cloth of the front and rear speakers 30 and 20, respectively.

Referring to the operation of the speaker system integrated with the front, rear speakers and subwoofer according to the present invention having the configuration as described above are as follows.

Referring back to the drawings, the speaker system 100 in which the front, rear speakers and subwoofers are integrated according to the present invention is, for example, a front that is installed in front of a listener normally provided in a speaker system for a home theater. The speaker (30), the rear speaker (20) (or surround speaker) and the subwoofer (11) that were installed behind the listener, are integrated into one case (10).

In particular, the subwoofer 11 and the front and rear speakers (30, 20) are separated, respectively, to enable selective use. Also in the power supply system, power can be applied to all the speakers 100 through one connector 41.

Therefore, as shown in FIG. 7, the connection between the speaker 100 and the AMP 52 is connected by one cable, and at the same time, the speaker 100 is powered by one connection using the connector 41. Authorization is possible.

In addition, the integrated speaker 100 according to the present invention provided on the left and right of the amplifier 52 and the screen device 51 has a radiated acoustic sound C output from the rear speaker 20 at the rear of the listener P. It is a directional speaker provided to be reflected and listened.

In more detail, the radiated acoustic sound C emitted from the rear speaker 20 is reflected on the wall, that is, the side wall and the rear wall, to be listened to by the listener P.

That is, although the radiating sound C of the rear speaker 20 is output from the front of the listener P and radiates, the radiating sound C is reflected from the rear of the listener P so that the rear of the listener P is rearward. In which the acoustic sound C is output and radiated to the listener P with the same effect.

And the radio sound (A, B) radiated from the front speaker 30 to be directly listened to the listener (P), the low-frequency direct radio sound directly radiated to the listener (P) of the radio sound of the rear speaker (20) The sound is absorbed by the sound absorbing member 23.

That is, the voice component (surround sound) radiated from the rear speaker 20 is not directly radiated toward the listener P. To this end, the sound absorbing member 23 is used.

By installing the subwoofer 11 at the bottom of the case 10, for example, low-frequency effect sound (LFE) is reproduced in 5.1ch surround reproduction. Therefore, 5.1ch surround sound reproduction can be realized with only two speaker systems 100 installed in front of the listener P, and the convenience of installation and the place of installation can be reduced, thereby greatly improving the usability of the consumer.

In addition, since the subwoofer 11 is integrated with the front and rear speakers 30 and 20, the crossover frequency of the front and rear speakers 30 and 20 and the subwoofer 11 is relatively high. Even if the sound source position of the subwoofer 11 is felt, there is no problem at all. That is, as shown in the figure, the front and rear speakers 30 and 20 can be extremely miniaturized than before.

In addition, even if the front and rear speakers 30 and 20 are miniaturized as described above, the installation stand is not necessary because of the installation, and the installation stand is not necessary even if the front and rear speakers 30 and 20 are installed together with the subwoofer 11. As a result, a separate installation place is not required, so the installation efficiency is high.

As described above, the speaker system in which the front and rear speakers and the subwoofer are integrated according to the present invention has the following effects.

Front speaker, rear speaker, and subwoofer are integrated, so there is no need to connect and install the speaker and subwoofer separately as in the prior art, and do not need the wire required for installation, and there is no need to arrange the wire There is no required cost, simplifying installation, and the overall manufacturing cost and installation cost can be low.

In addition, there is no need to install a separate rear speaker, and the number of speakers is reduced, so that the installation environment is improved and management is easy.

In addition, the front radiant sound allows the listener to listen directly, and the radiator of the rear speaker allows only the reflected sound to be heard, thereby improving the directivity of the speaker, which in turn improves the satisfaction of the sound quality.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
