High-fidelity combined loudspeaker box for curved screen

Abstract

The invention relates to a high-fidelity combined loudspeaker box for a curved screen. The high-fidelity combined loudspeaker box comprises a box body; the high-fidelity combined loudspeaker box is characterized in that the section of the box body is L-shaped; the box body is in a long shape with a wide end and a narrow end in an overhead view; the front side surface of the box body is divided into upper and lower two stages; the front side surface of the upper stage shrinks backwards, while the front side surface of the lower stage stretches forwards, and the front side surface of the upper stage and the front side surface of the lower stage are in transitional connection with each other through a middle plane; a bass loudspeaker unit of which a sound radiation direction faces right above the box body is mounted at the wider end of the top plane of the box body, and a treble loudspeaker unit and a midrange loudspeaker unit, of which the radiation directions both face right ahead of the box body, are mounted at the narrower end of the front side surface of the lower stage of the box body; furthermore, an inverted-phase sound outlet is formed in the box body. The high-fidelity combined loudspeaker box for the curved screen is capable of realizing the multiple-frequency splitting technical advantages of treble, midrange and bass of the loudspeaker box and also overcoming the sound replay defects of the combined loudspeaker; when used in combination with a large-screen video-audio apparatus, the high-fidelity combined loudspeaker box is capable of radiating sound with high fidelity and greatly improving the subjective sound hearing effect, and furthermore, the appearance can be beautified.

Description

technical field [0001] The invention relates to a loudspeaker sound box, in particular to a high-fidelity combination sound box for a curved screen suitable for use on audio-visual entertainment equipment such as a television set and a notebook computer, and belongs to the technical field of electroacoustic equipment. Background technique [0002] In the prior art, combined speakers used in TV sets can only use long strip structures and short-stroke small-caliber speaker units to radiate sound due to structural limitations, resulting in weak low frequencies and low sound pressure in the entire sound system, which is difficult for subjective listening. The effect is poor, and it cannot meet the high-fidelity sound playback requirements for large screens. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a high-fidelity combination speaker for a curved screen. The sound reproduction defect o...
