Abstract
One described in the utility model adjacent audio amplifier center angle of release structure, comprise audio amplifier body, the rear portion of adjacent audio amplifier body is hinged, hinged axis of rotation is arranged on contact-making surface when adjacent audio amplifier body two sides contacts, the side of audio amplifier body is provided with connecting plate near rear positions, connector is provided with between the connecting plate of adjacent audio amplifier, described connecting plate and connector are equipped with through hole, described through hole is equipped with screw rod, described connecting plate is positioned on contact-making surface when described adjacent audio amplifier body two sides contacts, and connecting plate is fixed on described audio amplifier body by latch.The utility model can ensure that sound box hanging gets up after angle of release degree, audio amplifier below can not toward retrodeviating, the audio amplifier is more there will not be more to walk back, because after audio amplifier has been walked back, the starting point of every audio amplifier high pitch is not just on same bar line, what just there will be that audio amplifier high pitch more down postpones is more severe, even and if several audio amplifiers hold angle successfully and put on the ground, the gravity of audio amplifier is still in centre.
Description
Technical field
The utility model relates to technology for loudspeaker box field, specifically, relates to a kind of adjacent audio amplifier center angle of release structure.
Background technology
Can use a large amount of audio amplifiers in present concert, the rear portion of adjacent audio amplifier is hinged, and the curved array of several audio amplifiers is lifted on stage both sides, to obtain preferably sound effect.
But, the hinged axle center of existing adjacent audio amplifier is at the rear portion of audio amplifier, consult Fig. 1, 2, when adjacent audio amplifier is hinged, two non-central angle of releases of audio amplifier, audio amplifier more prolongs more backward, because after audio amplifier has prolonged backward, the starting point of every audio amplifier high pitch is not just on same camber line, it is more severe that the audio amplifier high pitch that just there will be more down postpones, to open 5 degree, traditional loudspeaker can retrodeviate 5.23mm, and the wavelength of 10kzhz is about 34mm, traditional angle of release causes phase deviation 5/34=14% (360 × 0.14=52 degree), in like manner the wavelength of 15khz is 22mm, phase deviation 5/22=22% (360 × 0.22)=81 degree, so the angle of release of more than 10Khz in wide-angle time, not good acoustically.
Utility model content
The utility model overcomes shortcoming of the prior art, provide a kind of adjacent audio amplifier center angle of release structure, sound box hanging gets up after angle of release degree, and audio amplifier below can not toward retrodeviating, even if several audio amplifiers are held angle successfully and put on the ground, the gravity of audio amplifier is still in centre.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of adjacent audio amplifier center angle of release structure, comprise audio amplifier body, the rear portion of adjacent audio amplifier body is hinged, and described hinged axis of rotation is arranged on contact-making surface when adjacent audio amplifier body two sides contacts.
Further, the side of described audio amplifier body is provided with connecting plate near rear positions, connector is provided with between the connecting plate of adjacent audio amplifier, described connecting plate and connector are equipped with through hole, described through hole is equipped with screw rod, and described connecting plate is positioned on contact-making surface when described adjacent audio amplifier body two sides contacts.
Further, described connecting plate is fixed on described audio amplifier body by latch.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can ensure that sound box hanging gets up after angle of release degree, audio amplifier below can not toward retrodeviating, the audio amplifier is more there will not be more to walk back, because after audio amplifier has been walked back, the starting point of every audio amplifier high pitch is not just on same bar line, what just there will be that audio amplifier high pitch more down postpones is more severe, even and if several audio amplifiers hold angle successfully and put on the ground, the gravity of audio amplifier is still in centre.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in FIG. 3 to 7, one described in the utility model adjacent audio amplifier center angle of release structure, comprise audio amplifier body 1, the side of audio amplifier body 1 is provided with connecting plate 2 near rear positions, connector 3 is provided with between the connecting plate 2 of adjacent audio amplifier, connecting plate 2 and connector 3 are equipped with through hole 4, through hole 4 is equipped with screw rod 5, connecting plate 2 is positioned on contact-making surface when adjacent audio amplifier body 1 two sides contacts, realize on contact-making surface that hinged axis of rotation is arranged on when adjacent audio amplifier body 1 two sides contacts, the rear portion of adjacent audio amplifier body 1 by connecting plate 2 and connector 3 hinged.
Connecting plate 2 is fixed on the side of audio amplifier body 1 by latch 6.
Consult Fig. 6, adjacent audio amplifier body 1 center angle of release, would not occur audio amplifier after angle of release degree not on a radian, high pitch is not also just interfered and delay issue.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
