Abstract
The utility model relates to a tweeter of a linear array sound box. The tweeter is a horn loudspeaker, the horn is flat-triangle-shaped, and the inside of the horn is provided with a sound transmission channel; the horn is vertically arranged, the horn is enclosed by triangle side plates at left and right sides and sealing plates at up and down bottom surfaces, the small end of the horn is connected with a loudspeaker, and two sides of an opening of the big end of the horn are provided with reflecting plates; and an included angle of the small end of the horn is 40-45 DEG, an included angle between the two reflecting plates is 95-105 DEG, and the length of the horn is 220-250 mm. High frequency directivity is strongly superposed due to the specific shape of the horn, energy can be radiated further, and sound can be transmitted for a longer distance.
Description
Technical field
The utility model relates to audio amplifier, especially line array loudspeaker.
Background technology
Linear array loundspeaker box is generally comprised of the bass horn of middle loudspeaker and both sides, and because the linear array of its formation is narrow beam in main shaft vertical plane directive property, energy stack radiation at a distance, is therefore generally used for outdoor broadcasting.The loudspeaker that far and closely depends primarily on mid portion of a Linear array loundspeaker box radiation scope, according to using MAPP software analysis, the directive property of linear array is along with frequency rising directive property is more sharp-pointed, arrive certain frequency, during as 2kHz, it is radial that directive property is, and lobe appears in directivity pattern, at this moment the acoustic wave form of tweeter composition is grown up to be a useful person and is just worked, and the stack of high frequency directive property is strengthened.Loudspeaker high frequency directive property stack in existing Linear array loundspeaker box is not strong, and therefore energy emission scope is not far away.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Linear array loundspeaker box loudspeaker, and the stack of high frequency directive property is strong, and therefore energy emission scope is farther.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of Linear array loundspeaker box loudspeaker, and described loudspeaker is Horn loudspeaker, and described horn is flat triangle, and its inside is provided with sound transmission passage; Described horn is vertical setting, and described horn is surrounded by the triangle side plate of the left and right sides and the shrouding of upper bottom surface, and the small end of horn is connected with loudspeaker, and the large end opening both sides of horn are provided with reflecting plate; The angle of described horn small end is 40 ~ 45 °, and the angle between described two reflecting plates is 95 ~ 105 °, and the length of described horn is 220 ~ 250mm.The specific shape of the utility model horn makes the stack of high frequency directive property stronger, and energy emission obtains farther, and the propagation distance of sound is farther.
As improvement, in described horn, be provided with the dividing plate that sound transmission passage is divided into symmetrical halves, described dividing plate assumes diamond in shape.
As improvement, the triangle side plate of described horn is provided with installation fixed block.
The beneficial effect that the utility model compared with prior art brought is:
The specific shape of the utility model horn makes the stack of high frequency directive property stronger, and energy emission obtains farther, and the propagation distance of sound is farther.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of Linear array loundspeaker box, Linear array loundspeaker box is mainly comprised of the bass horn 2 of middle loudspeaker 1 and both sides.As shown in Figures 2 to 4, described loudspeaker 1 is Horn loudspeaker, and described horn is flat triangle, and its inside is provided with sound transmission passage 11, is provided with the dividing plate 16 that sound transmission passage 11 is divided into symmetrical halves in described horn, and described dividing plate 16 assumes diamond in shape.Described horn is vertical setting, and described horn is surrounded by the triangle side plate 13 of the left and right sides and the shrouding of upper bottom surface 15, and the small end of horn is connected with loudspeaker, and the large end opening both sides of horn are provided with reflecting plate 12; The angle b of described horn small end is 40 ~ 45 °, and the angle a between described two reflecting plates 12 is 95 ~ 105 °, and the length L of described horn is 220 ~ 250mm.The triangle side plate 13 of described horn is provided with installs fixed block 14, for installing and fixing horn.
The specific shape of the utility model horn makes the stack of high frequency directive property stronger, and energy emission obtains farther, and the propagation distance of sound is farther.
