Abstract

The utility model relates to a gain guiding horn for a loudspeaker. The gain guiding horn comprises an horn upper plate, a horn left-side plate, a horn right-side plate and a horn lower plate. The horn upper plate is welded to the horn left-side plate and the horn right-side plate, and the horn lower plate is welded to the horn left-side plate and the horn right-side plate. The gain guiding horn employs a rectangular horn form, the horn upper plate is flat, and the horn left-side plate, the horn right-side plate and the horn lower plate are all flaring curved surfaces. The sectional area of the horn is calculated by theoretical formulas. The technical effects of the gain guiding horn are that the horn is of light weight, thin thickness and low price, and has good low-frequency effects, water is hard to go into the horn, the horn is of good rainproof performance particular to a high pitch horn loudspeaker, and the loudspeaker employing the gain guiding horn can acquire directivity different from a common horn loudspeaker.

Description

Gain guiding horn for loud speaker

Technical field

The utility model relates to a kind of loud speaker horn, particularly gain guiding horn for a kind of loud speaker.

Background technology

The horn of common horn speaker adopts full symmetric design, the directive property of horn has symmetry, in the time that horn speaker is positioned at eminence horizontal positioned, have acoustic energy greatly and be diffused into sky, this part acoustic energy slatterns completely, how to reduce the waste of this part acoustic energy, traditional method is slightly downward by horn by installing installing rack additional, but this method causes the product form of installation not attractive in appearance, installation process is more loaded down with trivial details, and because needs tilt to install, easily cause the product after installation insecure, make sound propagate and there is very strong practicality towards the direction of needs, need to study the horn speaker that a kind of horizontal positioned still can make sound oliquely downward propagate for this reason.

Summary of the invention

In view of the requirement of above technology, the utility model provides a kind of loud speaker gain guiding horn, concrete technical scheme is, gain guiding horn for a kind of loud speaker, comprise horn upper plate, horn left plate, horn right plate, horn lower plate, it is characterized in that: horn upper plate and the welding of horn left plate, horn upper plate and the welding of horn right plate, horn lower plate and the welding of horn left plate, horn lower plate and the welding of horn right plate, adopt rectangular horn form, horn upper plate is plate shaped, horn left plate, horn right plate, horn lower plate is the exhibition curved surface shaped of wriggling, the sectional area of horn adopts theoretical formula to calculate.

Technique effect of the present utility model is lightweight, thin thickness, price is low, low-frequency effect good, it is good in horn mouth, to be not easy into water, water-resistant performance, particularly, for horn loudspeaker, adopt this horn can obtain the directive property that is different from common horn speaker.

Fig. 2 is right view of the present utility model.

Fig. 3 is vertical view of the present utility model.

Embodiment

As shown in Figure 1, 2, 3, comprise horn upper plate 1, horn left plate 2, horn right plate 3, horn lower plate 4, horn upper plate 1 welds with horn left plate 2, horn upper plate 1 welds with horn right plate 2, and horn lower plate 4 is welded with horn left plate 2, and horn lower plate 4 is welded with horn right plate 3, adopt rectangular horn form, horn upper plate 1 is plate shaped, and horn left plate 2, horn right plate 3, horn lower plate 4 are the exhibition curved surface shaped of wriggling, and the sectional area of horn adopts theoretical formula to calculate.

Its principle is by asymmetrical horn structure, make the acoustic axis of horn amesiality, thereby change the propagation angle of sound, making sound is not to propagate along dead ahead as traditional horn speaker, but have a certain degree with the normal of horn mouth, reaching sound in the situation of horn horizontal positioned tiltedly propagates below, this feature is positioned at high-altitude for horn speaker, and target audience be positioned at below situation there is special ease for use, simultaneously, also horn can be positioned over to ground uses, situation about using on ground is specially adapted to target audience and is positioned at the situation of eminence, for example stadiums, use this horn audience that just can aim at the mark that need not tilt up or down.

Claims

1. a gain guiding horn for loud speaker, comprise horn upper plate (1), horn left plate (2), horn right plate (3), horn lower plate (4), it is characterized in that: horn upper plate (1) and horn left plate (2) welding, horn upper plate (1) and horn right plate (2) welding, horn lower plate (4) and horn left plate (2) welding, horn lower plate (4) and horn right plate (3) welding, adopt rectangular horn form, horn upper plate (1) is plate shaped, horn left plate (2), horn right plate (3), horn lower plate (4) is the exhibition curved surface shaped of wriggling, the sectional area of horn adopts theoretical formula to calculate.
