Description

Integrated 5.1 channel or 7.1 channel stereo sound system {STEREOPHONIC SOUND SYSTEM FOR IMPLEMENTING 5.1 CHANNEL OR 7.1 CHANNEL SUSROUND EFFECT}

The present invention relates to an integrated 5.1-channel or 7.1-channel stereophonic sound system, and more particularly, it is possible to set the direction (angle) of the speaker according to the position of the listener to realize a more natural and realistic stereophonic sound. An improved integrated 5.1-channel or 7.1-channel stereophonic sound system is further provided with a 7.1-channel headphone output system to realize stereophonic sound through headphones.

Audio speaker systems are rapidly evolving from the initial two channels of one left and right speaker, which is the basic configuration of traditional stereo, to 5.1 channels, 6.1 channels, and 7.1 channels. The multi-channel speaker system is not composed of only left and right speakers, but is a method of arranging speakers to surround the listener, such as front left, front right, center (center), rear left and rear right.

For example, the 5.1-channel system has a center (C), front left (FL), front right (FR), rear left (F) to realize a three-dimensional realistic audio signal output from an audio device such as a home theater or a DVD player. RL), rear-right (RR) speaker and woofer or subwoofer. On the other hand, the 7.1-channel system refers to the 5.1 channel is arranged by adding a surround left (SBL) speaker and a surround right (SBR) speaker behind the listener.

Recently, a front surround sound system has been developed that forms a three-dimensional effect using a front speaker without additional side and rear speakers. The front surround sound playback system fixes the direction of some of the speakers included in the integrated speaker system by turning it at a certain angle to the left and right, and forms a three-dimensional effect by reflecting the wall of the sound beam output from the fixed speaker by turning it at a predetermined angle. The reflected sound makes the listener feel as though the sound is coming from the side and rear speakers.

However, such a conventional front surround sound reproduction system is manufactured at a fixed angle at the time of product shipment, and thus, there is a disadvantage in that it does not sufficiently obtain the intended stereoscopic sound effect in each condition of listening to the actual sound of the listener. Particularly in the current general living room form (the "c" shaped living room, which is open to one side by the kitchen), the conventional stereotyped front surround sound reproduction system is used to realize a natural and realistic three-dimensional sound level to satisfy the listener. I'm falling short.

On the other hand, technology that applies multi-channel to headphone, not speaker system, has recently emerged. The front left and right, rear left and right, center and woofer are arranged on the left and right ear parts of the headphone, respectively. The woofer signal in Eq. Is implemented in a manner in which vibration is usually generated by the vibrator V in the headphones. For example, in the case of 5.1-channel headphones, three units ([FR, SR, C], [FL, SL, C]) and a vibrator serving as a woofer are provided on the left and right sides, respectively. In this case, surround left (SBL) and surround right (SBR) speakers are additionally arranged in left and right units.

The object of the present invention is to provide a new integrated 5.1-channel or 7.1-channel stereophonic sound system that can set the direction (angle) of the speaker according to the position of the listener, unlike a conventional stereophonic sound system in which all the speakers face the front.

Another object of the present invention is to provide an integrated 5.1-channel or 7.1-channel stereophonic sound system that can implement stereophonic sound through headphones by additionally providing a 5.1-channel or 7.1-channel headphone output system in the integrated speaker.
