Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0021] As shown in the figure, the dumbbell-type inverter speaker with treble compensation in the embodiment is mainly composed of a front cavity 1, a rear cavity 2, a mid-range speaker unit 3, a front tweeter unit 4 and a side tweeter unit 5.

[0022] Such as Figure 1~Figure 4 As shown, the front cavity 1 and the rear cavity 2 form an oblong box, the panel of the front cavity 1 is provided with several screw holes 1e, and the inner wall of the rear cavity 2 is provided with several The screw post 2c, the screw post 2c corresponds to the screw hole 1e one by one, and the front cavity 1 and the rear cavity 2 are fastened and connected through the screw hole 1e and the screw in the screw post 2c.

[0023] Such as Figure 1~Figure 4 As shown, the length direction of the front cavity 1 is provided with two mid-bass speaker installation holes 1a arranged symmetri...

Abstract

The invention relates to a dumbbell-type phase-inverted sound box with treble compensation, which includes a box body, and is characterized in that: the box body is flat and long, and two centrally symmetrically arranged mid-bass speaker installation holes are arranged on the length direction of the front panel of the box body. A mid-bass speaker unit is installed in the mid-bass speaker installation hole; a front tweeter installation hole is installed in the middle of the two mid-bass speaker installation holes, and a front tweeter unit is installed in the front tweeter installation hole; two mid-bass speaker units It is set on the same plane and coaxial with a front tweeter unit, and their sound radiation direction is toward the front of the box; there is a side tweeter installation hole on the long side of the box, and a side tweeter is installed in the side tweeter installation hole unit. The invention has the advantages of ingenious, compact and reasonable structure, wide sound field, small distortion, good balance and low frequency, high withstand power, good 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.
