Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 and fig. 2, the utility model discloses a novel audio amplifier of panorama sound, include: the box 1, the box 1 outside is equipped with screen panel 2, box 1 bottom is equipped with back plate 3.

As shown in fig. 1 and 2, a plurality of accommodating grooves 12 are formed in the box body 1, and speakers 13 are disposed in the accommodating grooves 12. Be equipped with in the box 1 and accomodate chamber 14, accomodate the intracavity and be equipped with audio amplifier frequency divider 15. The accommodating groove 12 is distributed on the periphery of the accommodating cavity 14, the accommodating groove 12 penetrates through the box body 1, the loudspeaker 13 is arranged in the accommodating groove 12, an opening of the loudspeaker 13 is opened towards the mesh enclosure 2 and exposed out of the box body 1, and an extending direction of the opening of the loudspeaker 13 and a horizontal plane direction at the bottom of the box body 1 form an included angle of 30 degrees. The loudspeaker 13 is connected to the loudspeaker box divider 15. The novel audio amplifier of panorama sound is equipped with a plurality ofly speaker 13, it can make a plurality of speakers of one side send different sounds one by one, more really build the audio by far and near, and the cooperation ceiling adds establishes the audio amplifier, realizes that the sound field surrounds, shows more sound details, promotes spectator's sight shadow impression. The method not only improves better surround sound experience in the horizontal plane direction, but also enables listeners to feel the level and the change of sound in the vertical height, fills the gap of scene sound effect at the top due to the fact that the space on the cantilever is lack of additional sound channels, and enables the whole sound system and the picture to be full and complete.
