Abstract
The utility model discloses a voice box structure with eight acoustic radiators, which is formed by arranging six loudspeaker units and two passive radiators according to the following sequence: two passive radiators are arranged on the first position and the fifth position in the array, the loudspeaker voice boxes are arranged on a straight line or an arc line similar to the straight line, and low-frequency frequency response is improved.
Description
Technical field
The utility model relates to the method to set up and the device of the audio amplifier with eight acoustic radiators, and a kind of loudspeaker box structure with eight acoustic radiators comprises loudspeaker unit and passive radiator erection sequence in its body structure and the audio amplifier.
Background technology
The applicant Shen Yong, the safe and comfortable five-sound source loudspeaker array with wide radiation angle that proposes, application number: 201010140934.7; Shen Yong, Dong Guiguan, propositions such as Xia Jie are wide radiation angle six sound source to nine sound source loudspeaker arrays, application number: 201010586885.X, five to nine identical loud speakers arranging according to the order of sequence by the signal mixing that amplitude is different with phase place, five to nine different loud speakers through design that perhaps that amplitude is identical with phase place signal mixing is arranged are according to the order of sequence realized the optimization of five-sound source to nine sound source loudspeaker array directive property.But do not provide the structure with the obvious optimization of directive property of the audio amplifier of eight acoustic radiators.
The utility model content
The purpose of this utility model is: propose a kind of loudspeaker box structure with eight acoustic radiators, comprise loudspeaker unit and passive radiator erection sequence in its body structure and the audio amplifier.After the vanning of unit and passive radiator, actual measurement shows that its directive property significantly optimizes.
The purpose of this utility model is achieved in that the loudspeaker box structure with eight acoustic radiators, six loudspeaker units and two passive radiators in eight acoustic radiators in the audio amplifier are constituted according to following arrangement, loudspeaker acoustic enclosure refers to the loudspeaker acoustic enclosure with eight acoustic radiators that linear array or near linear (less radian) camber line is arranged, and two passive radiators come first in array and the 5th position; Make it all have wide radiation angle in operating frequency range, the low frequency frequency response is improved.
The body structure of eight acoustic radiator audio amplifiers of the utility model design, and loudspeaker unit and passive radiator are installed in array in regular turn.Loudspeaker acoustic enclosure with eight acoustic radiators described in the utility model refers generally to the loudspeaker acoustic enclosure with eight acoustic radiators that linear array or near linear (less radian) camber line is arranged, and also can relate to the loudspeaker acoustic enclosure of curved arrangement.Eight acoustic radiator audio amplifiers described in the utility model refer generally to many sound source loudspeakers array that a plurality of acoustic radiators that (less radian) camber line of horizontal linear array or near linear arranges constitute.
The utility model improves: the loudspeaker unit horizontal positioned is constituted " sound beam " formula transverse arrangement of turbo.Be specially adapted to " sound beam " (sound girder, sound crossbeam) formula transverse arrangement of turbo of loudspeaker array horizontal positioned is used.
The emulation that the utility model provides, experimental data are example with the linear pattern loudspeaker acoustic enclosure all.And for the little loudspeaker acoustic enclosure of degree of crook, its optimization characteristics are maintained substantially.So can according to actual needs linear pattern be set, perhaps have the loudspeaker acoustic enclosure of less radian.
The beneficial effects of the utility model are: the loudspeaker acoustic enclosure with eight acoustic radiators, six loudspeaker units and two passive radiators are arranged in order according to certain rule, make it in operating frequency range, all have wide radiation angle, and the low frequency frequency response is improved.At this moment, sound beam of the present utility model all has the radiation angle of broad in the horizontal direction with vertical direction, is easy to obtain radiated sound field more uniformly, and the low frequency frequency response of sound beam also can be significantly improved.The sound beam is easy for installation in some cases and attractive in appearance, practical.

Specific implementation method
Below with formal specification specific implementation method of the present utility model for example.Fig. 1-the 3rd the utlity model has body structure and the loudspeaker unit and the passive radiator erection sequence of the audio amplifier of eight acoustic radiators.
Body structure is made casing as Figure 1-3, and loudspeaker unit 1 and passive radiator 2 are installed in regular turn.Box sizes is selected according to the size of actual loudspeaker unit and passive radiator; The front is installed six loudspeaker units and two passive radiators in regular turn, and the size of unit and passive radiator is decided by the size of material object.Two passive radiators come first in the array and the 5th position or the 4th and 8 positions.
The utility model particularly is: according to loudspeaker unit and passive radiator, design has the body structure of the audio amplifier of eight acoustic radiators, and as shown in Figure 1, box sizes is selected according to the size of actual loudspeaker unit and passive radiator; The front is installed six loudspeaker units and two passive radiators (the same loudspeaker unit of structure, the device of short of electricity source driver part) in regular turn, and the size of unit and passive radiator is decided by the size of material object.
Claims (2)
1. the loudspeaker box structure that has eight acoustic radiators, it is characterized in that: six loudspeaker units and two passive radiators in eight acoustic radiators in the audio amplifier are constituted according to following array, two passive radiators come first in array and the 5th position, loudspeaker acoustic enclosure refers to the loudspeaker acoustic enclosure with eight acoustic radiators that the camber line of linear array or near linear is arranged, and the low frequency frequency response is improved.
2. the loudspeaker box structure with eight acoustic radiators as claimed in claim 1 is characterized in that: loudspeaker unit and two passive radiation volume array horizontal positioned constitute " sound beam " formula transverse arrangement of turbo.
