Description

Speaker device for TV with genre setting function {SPEAKER APPARATUS FOR TELEVISION}

The present invention relates to a TV-only speaker device having a genre-specific setting function using a high and low loudspeaker together with a midrange speaker. More particularly, the present invention relates to a speaker that is displayed on an LCD panel as a user controls a remote control button according to the characteristics of each genre. The present invention relates to a speaker-equipped television-only speaker device having a high, mid and low tone setting menu function for each genre (eg, movie, sports, drama, music, etc.) to transmit sound sources through.

Conventionally, amplifier built-in speakers have been developed in various products and widely installed and spread in electronic products and communication devices. However, such conventional speakers are mainly music-only speakers or computer-only speakers, which are mainly mainstream. Since their use is mainly limited to listening to music, they are classified into genres of music such as jazz, rock, classical and pop. It was only there.

On the other hand, in the television field, expensive televisions with built-in setting functions for each genre have been introduced, but they have the following limitations. First, since the function itself is only a part of the TV function, the concept is different from that of a dedicated speaker. In particular, the sound coming out of the TV speaker is suppressed as much as possible from the sound sources output by each entertainment medium. There was a significant difference from the actual sound source.

As described above, the speaker mounted on the existing TV has difficulty in controlling the sound source freely due to the limitations of the TV itself, and it was also difficult to develop a function of receiving and adjusting the TV sound source using a general speaker. Therefore, in order to maximize the sound effect of each genre by listening to the sound source for each genre viewed from the television close to the actual sound, it is necessary to have a sound source setting function for each genre using a TV-only speaker. In particular, since the preferred sound (combination of high, mid and low) is different for each race and country, if the speaker has the ability to set the sound source, a speaker product having various performances according to each race and country's taste is recommended. Can develop.

In particular, modern televisions are gateway aggregates of all entertainment media (eg, digital / analog set-top boxes, DVD / CD / VCD / VHS and game boxes, etc.). Therefore, the demand of consumers for a dedicated speaker having a function that can maximize the audio effect of each medium is increasing.

In accordance with the demands of the times, the inventors have focused on the fact that, in order to obtain the sound effect closest to the real sound source through the television, a speaker that first reinforces the high and low parts of the sound source closest to the real sound is required. The need to develop a dedicated speaker has led to the present invention.

Accordingly, the present invention provides a genre setting function that can be applied to the sound source setting technology to the mid, low and high speakers through the remote control to maximize the sound effect of the entertainment genre of the TV in order to solve the problems of the conventional speaker as described above It is an object of the present invention to provide a dedicated speaker device including a television.
