Abstract
The invention discloses a coaxial array horn sound box composed of two speakers in n rows and N columns and a horn box, wherein n>=1, and N>=1. The coaxial array horn sound box is characterized in that the horn box consists of a box and a horn, the throat of the horn is connected with a speaker mounting surface of the box, the speakers are coaxial speaker units (coaxial units for short), and the coaxial units are mounted on a box panel, wherein n coaxial units are longitudinally arranged and mounted on the box panel at the throat of the horn, and N coaxial units are transversely arranged and mounted on the box panel at the throat of the horn. The tweeter of each coaxial unit is mounted in the center of the woofer unit, and the positions of the tweeter and the woofer are coaxial, which ensures the coverage of the whole hearable frequency band and satisfies a point sound source speaker required by an ideal linear array.
Description
Art
The present invention relates to a kind of for audio playback technology for loudspeaker box, especially coaxial array bugle audio amplifier.
Background technology
The object that array bugle technology for loudspeaker box will reach is in range of audibility audio frequency, produce long drive sound field or flat directive property, symmetric array bugle audio amplifier produces long drive spherical wave directive property, longitudinal array bugle audio amplifier produces the flat directive property of horizontal plane, horizontal array bugle audio amplifier produces the flat directive property of vertical plane, and ideal array bugle audio amplifier equidistantly should be arranged by the point sound source loud speaker covering range of audibility frequency response.Current known array bugle audio amplifier is separately independently arranged on casing by middle bass unit and alt unit, bass array speaker in medium and low spectrum loudspeaker composition, medium and high pitch loudspeaker composition alt array speaker, the two is mechanically combined, and known array speaker all also exists following imperfection part:
(1) known array speaker due to be multiple narrow frequency array speaker mechanical combination together, the radiation waveform combined of multiple narrow frequency array speaker is less than the standard of ideal array, and therefore performance reduces greatly;
(2) in known array speaker, bass and alt, owing to installing respectively, create serious phase distortion, and therefore do not meet the full range point sound source requirement of linear array, its acoustic irradiation does not reach the long drive of expection and flat directive property, have very large sound wave distortion.
(3) in known array speaker, bass and alt are installed respectively, and alt array uses bugle usually, and middle bass is without bugle, and the two sound property differs greatly, and waveform reduction distortion produces serious distortion.
(4) use because known array high pitch bass unit is separately independent, therefore install the cabinet panel that needs are larger, volume is comparatively large, and produce, use inconvenience, cost is higher.
Summary of the invention
For overcoming the deficiency of known technology, the invention provides a kind of coaxial array bugle audio amplifier, by longitudinal n coaxial loudspeaker unit (being called for short same axle unit), laterally N number of same axle unit and bugle casing composition, wherein, n >=1, N >=1, it is characterized in that: bugle casing is made up of casing and bugle two parts, bugle throat is connected with casing loudspeaker installed surface, loud speaker is coaxial loudspeaker unit, be called for short same axle unit, each same axle unit is installed on cabinet panel, wherein, n is arranged on the cabinet panel of bugle throat with axle unit longitudinal arrangement, N number of coaxial unit transverse arrangement is arranged on the cabinet panel of bugle throat.The high pitch of above-mentioned same axle unit is arranged on the center of bass unit, and high pitch and the position of bass form the installation relation of coaxial concurrent, to ensure both to cover whole range of audibility frequency range, meets again the point sound source loud speaker required for ideal array.
The technical solution adopted for the present invention to solve the technical problems is:
Coaxial array bugle audio amplifier, the multiple coaxial loudspeaker unit merged by high and low sound and forming with the casing of bugle, wherein N number of coaxial unit transverse is arranged on cabinet panel equally spacedly, n is longitudinally arranged on cabinet panel equally spacedly with axle unit, transversely arranged quantity N >=1, longitudinal arrangement quantity n >=1, the throat of bugle is connected with the panel installing loudspeaker, is the aditus laryngis place that same axle unit is in bugle.
The invention has the beneficial effects as follows by use realize point sound source characteristic with axle unit, equidistantly arrange by multiple unit transverse, longitudinal direction again, again by the diffusion loading effect of bugle, effectively ensure that the radiation characteristic of long drive sound field, make coaxial array bugle audio amplifier become comparatively ideal array speaker.
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of coaxial array bugle audio amplifier.
Fig. 1-1 is the transverse sectional view of coaxial array bugle audio amplifier.
Fig. 1-2 is the longitudinal sectional view of coaxial array bugle audio amplifier.
Fig. 2 is a kind of special case schematic diagram of coaxial array bugle audio amplifier.
Fig. 3 is that multiple small gauge coaxial array bugle audio amplifier is stacked into many lattice coaxial array bugle audio amplifier schematic diagram.
Specific embodiment is:
Fig. 1, Fig. 1-1, Tu1-2Zhong, regularly arrange with axle unit 1-1 and be arranged on the loudspeaker installation panel 1-2 of casing 1-4, coaxial cell S PKn1, SPKn2 ... SPKnN laterally equidistantly installs along cabinet panel, coaxial cell S PK1N, SPK2N ... SPKnN longitudinally equidistantly installs along cabinet panel, wherein n >=1, N >=1, the aditus laryngis of bugle 1-3 is connected with panel, and same axle unit is distributed in aditus laryngis plane just.
In Fig. 2, when n >=2, will form a special case of coaxial array bugle audio amplifier during N=1, its performance is desirable longitudinal linear array characteristic, and its long drive sound field and horizontal directivity all will reach perfect condition.
In Fig. 3, when n, N value is very large, bugle casing adopts modular construction, both large bugle casing is divided into multiple small-sized bugle casing, and carries out the coaxial bugle audio amplifier of the many lattice of stacking formation with modular system, the transversely arranged H of small-sized bugle audio amplifier quantity after segmentation
