Description

Soundbar equipped with ultra-directional speakers{SOUNDBAR EQUIPPED WITH ULTRADIRECTIONAL SPEAKER}

The present invention relates to a sound bar equipped with a super-directional speaker, and more specifically, to a sound bar equipped with a super-directional speaker that improves stereoscopic sound reproduction quality by using a super-directional speaker.

Today's movie soundtracks are delivered in surround format for a variety of playback channels. The most recent audio formats offer the possibility of immersive sound reproduction. With immersive formats, legacy surround sound formats (e.g. 5.1 or 7.1), which can faithfully reproduce sound only in the horizontal plane, are extended to loudspeakers placed at various heights. Therefore, sound can be faithfully reproduced in 3D space.

Audiophiles can install speakers wherever they need them, including height speakers, but most consumers tend to avoid the effort of installing a traditional surround sound setup. Therefore, mounting additional loudspeakers in the ceiling may be preferred by even fewer consumers. Nevertheless, home consumers want the benefits of improved sound quality.

Soundbars have become widely available to reproduce high-quality sound without the need to install standalone loudspeakers. Soundbars offer better sound quality than most loudspeakers built into flat screens, and can produce virtual surround through special processing and loudspeaker layout.

In the case of conventional sound bars, it is explained that height speakers are installed on the upper surface to reflect sound waves from the ceiling to enhance three-dimensional sound for consumers. However, in reality, simply using ordinary speakers as height speakers reduces sound quality due to interference. It is difficult to expect any improvement in stereophonic sound as it only provides negative effects.
