Abstract
The utility model relates to a linear array loudspeaker, comprising a casing and a loudspeaker unit inside the casing, wherein the loudspeaker unit comprises a middle-pitch loudspeaker and a high-pitch loudspeaker; and the high-pitch loudspeaker of the linear array loudspeaker is of a horn loudspeaker, with the horn part shaped like a flat triangle with horizontal direction no less than 90 degrees and vertical direction no greater than 30 degrees. The linear array loudspeaker of the utility model adopts a self-made horn made of wood, with the horizontal direction of the designed self-made horn no less than 90 degrees and the vertical direction thereof no greater than 30 degrees. The linear array loudspeaker is capable of substantially reducing sound interference and the ununiformity of amplitude-frequency response.
Description
Technical field:
The utility model relates to a kind of public address speaker system, particularly a kind of line array loudspeaker.
Background technology:
In order to be applicable to the outdoor public address of area broadness, domestic and international many manufacturers have all designed line array loudspeaker miscellaneous system.Yet the method for designing great majority all more roughly the same.Existing outdoor public address speaker system, owing to be subjected to the line source Theory Influence, installation loudspeaker unit as much as possible in single system is all embodied a concentrated reflection of in its design.In order to realize this purpose, usually middle and high sound loudspeaker unit is installed in the casing of V word structure, system's directive property of forming is still between point sound source (high frequency) and line source (low frequency), its high frequency (more than the 3KHz) exists that vertical directivity is excessive, horizontal directivity is sharp-pointed, the effect as far as possible little with horizontal directivity broadness, the vertical directivity of our actual needs is just in time opposite, the above line source of 2KHz is difficult to realize that acoustic interference is very serious; (the amplitude-frequency response unevenness that the acoustic interference of actual measurement of 0.6KHz~3KHz) causes is stronger than the influence of pectination characteristic for its intermediate frequency.The result is very undesirable, gets half the result with twice the effort, It dones't help the situation.
Summary of the invention:
A kind of horizontal directivity broadness, the vertical directivity outdoor public address speaker system as far as possible little, that can be used in the area broadness that the utility model is researched and developed in order to solve above-mentioned the deficiencies in the prior art just.
The utility model can be realized by following technological means:
A kind of line array loudspeaker of the present utility model, described line array loudspeaker comprise the loudspeaker unit in casing and the casing; Loudspeaker unit comprises Squawker, high pitch loudspeaker; High pitch loudspeaker in the described line array loudspeaker is a horn speaker, and horn partly is level and points to 〉=90 °, the vertical flat triangle shape that points to≤30 °.
The horn of described horn speaker partly adopts wood materials to make.
A kind of line array loudspeaker of the present utility model adopts the self-control horn of wooden structures, the self-control horn horizontal directivity of design 〉=90 °, and vertical directivity≤30 ° can reduce acoustic interference significantly, have also reduced the amplitude-frequency response unevenness simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Specific embodiment:
With reference to the accompanying drawings 1, a kind of line array loudspeaker of the present utility model comprises a plurality of loudspeaker units in casing and the casing; Loudspeaker unit comprises Squawker 1, high pitch loudspeaker 2; High pitch loudspeaker in the line array loudspeaker is a horn speaker, and horn 3 parts are level and point to 〉=90 °, the vertical flat triangle shape that points to≤30 °.
This is because the acoustic characteristic of system configuration and loudspeaker unit has determined to realize the particularity of line source, if line source with respect to medium-high frequency, the acoustic interference influence that brings so is excessive, its replay quality is not as good as the point sound source excellence, closely the system of Shi Yonging needs point sound source, has only the system of remote use just to need line source.Loss on the transmission range can remedy at power amplifier, and design focal point is placed on horizontal directivity.And the key that solves directive property control is the design of horn speaker.Horn speaker in the market can not be satisfied the demand, thus adopt the self-control horn speaker of wooden structures, and horizontal directivity 〉=90 of design °, vertical directivity≤30 ° had both reduced acoustic interference, had also reduced the amplitude-frequency response unevenness simultaneously.
A kind of line array loudspeaker of the present utility model, medium-high frequency definition, angle of coverage significantly improve.Because each group linear system is carried out power division by different amplifiers, the acoustic pressure of far and near sound field can be accomplished evenly substantially.
Although it is pointed out that here the utility model is described in detail, with regard to this area staff, the similar modification of the class Sihe of making on this basis all should belong to the utility model protection range.
Claims (2)
1. line array loudspeaker is characterized in that: described line array loudspeaker comprises the loudspeaker unit in casing and the casing; Loudspeaker unit comprises Squawker, high pitch loudspeaker; High pitch loudspeaker in the described line array loudspeaker is a horn speaker, and horn partly is level and points to 〉=90 °, the vertical flat triangle shape that points to≤30 °.
2. a kind of line array loudspeaker according to claim 1 is characterized in that: the horn of described horn speaker partly adopts wood materials to make.
