Problems solved by technology

However, due to the increasingly obvious thinning trend of flat-panel TVs, the structure of supporting speaker products is required to be thinner, and it is difficult to obtain better sound quality when multiple traditional speaker units are integrated in a thinner space structure.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0022] As shown in the figure: the horn-type multi-point excitation speaker box in the embodiment is mainly composed of an upper shell 1, a woofer unit 2, a lower shell 3, a rear damping ring 4, a tweeter unit 5, a front damping ring 6, and a horn 7 And screw 8 etc. are formed.

[0023] Such as Figure 1~Figure 3 As shown, the quantity of the woofer unit 2 is two, and the structural properties of the two woofer units 2 are exactly the same; the quantity of the tweeter unit 5 is also two, and the structural properties of the two tweeter units 5 are also the same. Exactly the same; the box body is prolate, the upper surface of the box body is provided with two upper mounting holes 1a distributed along the direction of its long axis, and the lower surface of the box body is provided with two holes distributed along the direction of its long axis. The lower mount...

Abstract

A horn type multi-point excitation loudspeaker enclosure comprises an enclosure body, bass loudspeaker units (2) and high pitch loudspeaker units (5), and is characterized in that: there are at least two bass loudspeaker units (2) and the number of the high pitch loudspeaker units (5) is the same as that of the bass loudspeaker units (2); the enclosure body is flat and elongated and is provided with lower mounting holes (3a) and upper mounting holes (1a), the number of the lower mounting holes (3a) and the upper mounting holes (1a) is the same as that of the bass loudspeaker units (2), the bass loudspeaker units (2) are mounted in the upper mounting holes (1a) and the lower mounting holes (3a); a plurality of side holes (1b, 3b) distributed along a long shaft of the enclosure body are arranged on the long side of the enclosure body, the number of the side holes (1b, 3b) is the same as that of the high pitch loudspeaker units (5), and the high pitch loudspeaker units (5) are mounted in the side holes (1b, 3b); a horn (7) is arranged in front of the high pitch loudspeaker units (5), and the horn (7) is provided with bugles (7a) in one-to-one correspondence with the high pitch loudspeaker units (5).

Description

technical field [0001] The invention relates to a loudspeaker box, in particular to a horn-type multi-point excitation loudspeaker box loaded with horns, belonging to the technical field of electroacoustics. Background technique [0002] In the prior art, loudspeaker products used in large-size high-end LCD and PDP flat-panel TVs generally use multiple speaker units to form a speaker box to obtain a wider frequency response bandwidth and better high, medium and low frequency bands. sound quality. However, due to the increasingly obvious thinning trend of flat-panel TVs, the supporting speaker products are required to have a thinner structure, and it is difficult to obtain better sound quality when multiple traditional speaker units are integrated in a thinner space structure. Therefore, it is extremely important to seek a new type of speaker box, and obtain the best frequency response curve and sound quality through the arrangement and combination of multiple speaker units ...
