Problems solved by technology

[0002] In the prior art, speakers used in LCD, OLED and other flat-panel TVs usually use multiple speakers to form a "sound column" array, although the maximum sound pressure level can be increased, but due to the interference between multiple speakers, the directional Narrow sex
In order to improve the high-frequency directivity of the speaker array, a dumbbell structure with a front tweeter at the vertical center position of two identical mid-bass speakers appeared. , small distortion, good balance and low frequency, high power withstand, etc., but because the two mid-bass speakers will still interfere with each other, it will cause shortcomings such as narrow vertical directivity and poor high frequency.

Abstract

The invention relates to a dumbbell reverse-phase sound box with high pitch compensation. The sound box comprises a box body and is characterized in that the box body is long and flat, two low-mid pitch loudspeaker installation holes which are in center symmetry are formed in a front panel of the box body in the length direction, and a low-mid pitch loudspeaker unit is installed in each low-mid pitch loudspeaker installation hole. A front high pitch loudspeaker installation hole is formed in the middle of the two low-mid pitch loudspeaker installation holes, and a front high pitch loudspeaker unit is installed in the front high pitch loudspeaker installation hole. The two low-mid pitch loudspeaker units and the front high pitch loudspeaker unit are located coaxially on the same plane, and the sound of the units is radiated towards the front of the box body. A lateral high pitch loudspeaker installation hole is formed in a long side of the box body, and a lateral high pitch loudspeaker unit is installed in the lateral high pitch loudspeaker installation hole. The dumbbell reverse-phase sound box is ingenious, compact and reasonable in structure, wide in sound field, small in distortion, good in balance degree and low frequency, high in bearable power and good in vertical directivity and high frequency performance.

Description

technical field [0001] The invention relates to a loudspeaker sound box, in particular to a dumbbell-type phase-inverted sound box with treble compensation suitable for use on a television, and belongs to the technical field of electroacoustics. Background technique [0002] In the prior art, speakers used in LCD, OLED and other flat-panel TVs usually use multiple speakers to form a "sound column" array, although the maximum sound pressure level can be increased, but due to the interference between multiple speakers, the directional Sex narrow. In order to improve the high-frequency directivity of the speaker array, a dumbbell structure with a front tweeter at the vertical center position of two identical mid-bass speakers appeared. , small distortion, good balance and low frequency, and high power withstand, but because the two mid-woofers still interfere with each other, it will cause shortcomings such as narrow vertical directivity and poor high frequency.
