In addition, in the present embodiment, when this baffle main body 102 is set as linear pattern or broken line type, also linear pattern or broken line type can be correspondingly set as the above-mentioned support frame 101 fixing this baffle main body 102.
In an execution mode of the present embodiment, as shown in Figure 1, baffle main body 102 is provided with perforate 1021; As shown in Figure 2, audio amplifier 104 is positioned at the rear of perforate 1021, the loud speaker face 1041 of audio amplifier 104 is positioned at same level with the baffle main body 102 at perforate 1021 place corresponding to it, the sounding of audio amplifier 104 can be guaranteed thus, and, as shown in Figure 5, between this perforate 1021 and audio amplifier 104, be provided with sealing frame 401, the audio frequency that can prevent gap from additionally causing thus rings peak valley.Any sealing means of the prior art all comprises in the present embodiment.Wherein, sealing frame 401 also can adopt sheet material, and uses screw to be fixed, and certain the present embodiment is not in this, as restriction.
In the present embodiment, the area of perforate 1021 can be greater than the projected area of audio amplifier 104 in baffle main body 102, structure thus, can ensure that the audio amplifier of any shape can pull out from perforate 1021.
Structure thus, achieves the acoustics baffle that can design processing in advance, and can realize the on-the-spot Fast Installation of acoustics baffle device, and, the acoustic radiation properties deteriorate quoted when audio amplifier being placed in ground can be prevented, thus the tonequality of playback sound can not be affected.
In an execution mode of the present embodiment, as shown in Figure 2, sound box bracket 103 can comprise: rack body 1031, audio amplifier lower bolster 1032, slide mechanism 1033, audio amplifier upper padding plate 1034 and handle 1035.Wherein, audio amplifier lower bolster 1032 is fixed on rack body 1031, slide mechanism 1033 is fixed on this audio amplifier lower bolster 1032, audio amplifier upper padding plate 1034 is positioned on slide mechanism 1033, and, this audio amplifier upper padding plate 1034 relative to slide mechanism 1033 slide anteroposterior, this audio amplifier upper padding plate 1034 can place above-mentioned audio amplifier 104 under external force, and handle 1035 is arranged on a side of the close baffle main body 102 of audio amplifier upper padding plate 1034.Structure thus, 1035 audio amplifier 104 and audio amplifier upper padding plate 1034 can be pulled out from the perforate 1021 of baffle main body 102 by shaking hands, thus audio amplifier etc. break down need to safeguard time, a people just can shift out heavy audio amplifier quickly and easily and modify, thus realizes Fast-Maintenance.
Fig. 6 is the vertical view of the slide mechanism in the utility model embodiment.In the present embodiment, as shown in Figure 6, slide mechanism 1033 can comprise: framework 1036 and roller bearing 1037.As shown in Figure 2 and Figure 6, framework 1036 is fixed on audio amplifier lower bolster 1032, and roller bearing 1037 is arranged in framework 1036, this roller bearing 1037 can roll along the fore-and-aft direction of baffle main body 102 under external force, further, roller bearing 1037 has certain damping characteristic, and audio amplifier can be prevented to be free to slide.
In the present embodiment, as shown in Figure 2, audio amplifier upper padding plate 1034 is also positioned at the rear (not shown) of perforate 1021, be convenient to along with audio amplifier is drawn out together, therefore, between perforate 1021 and audio amplifier upper padding plate 1034, also gap may be there is, then in the present embodiment, sealing frame 401 is also arranged between audio amplifier upper padding plate 1034 and perforate 1021, as shown in Figure 7.Structure thus, can prevent the audio frequency additionally caused by the gap between perforate and audio amplifier upper padding plate from ringing peak valley.In the present embodiment, sealing frame 401 can cover the side of the close baffle main body 102 of this audio amplifier upper padding plate 1034, also can not cover, specifically depend on performance.
In the present embodiment, handle 1035 uses soft thin material usually, as leather etc., occurs to prevent handle 1035 and sealing frame 401 constructive interference installed.
Below the installation and maintenance process of acoustics baffle device 10 of the present utility model is described, with the structure of clear and definite this acoustics baffle device 10.
First, the bulk of installing the space of acoustics baffle device is as required processed (such as, being processed as the section bar of 50mm × 50mm) support frame 101, installs after transporting scene to this support frame 101, as shown in Figure 2, ground is fixed in.By by after good for baffle main body 102 processing of cutting, this baffle main body 102 is screwed on support frame 101, as shown in Figure 1.In the present embodiment, be not limited to the form shown in Fig. 1 and 2, support frame 101 and baffle main body 102 can be processed as linear pattern or broken line type respectively.
Then, sound box bracket 103 is placed in the rear of baffle main body 102, in the present embodiment, during in order to ensure to observe from the front of baffle main body 102 or rear, audio amplifier 104 faces the perforate 1021 of baffle main body 102, can precalculate the height of sound box bracket 103 according to the distance of perforate 1021 to ground and process, but also can be not limited thereto, such as, the Height Adjustable of the rack body 1031 of sound box bracket 103 can be made, ensure that audio amplifier 104 faces the perforate 1021 of baffle main body 102 with this.After placing sound box bracket 103, audio amplifier 104 is positioned on the audio amplifier upper padding plate 1034 of sound box bracket 103.
Finally, sealing frame 401 is screwed in baffle main body 102, thus, when sealing frame 401 is for sealing the gap between audio amplifier and perforate, during from the forward observation baffle device of baffle main body 102, only can see that the loud speaker face of audio amplifier is from baffle main body 102, as shown in Figure 5; And when sealing frame 401 is for sealing the gap between audio amplifier upper padding plate and perforate, during from the forward observation baffle device of baffle main body 102, the handle 1035 can seen the loud speaker face of audio amplifier, the above-mentioned side of audio amplifier upper padding plate and be arranged on this side, as shown in Figure 7.
Thus, achieve the acoustics baffle lightweight, processing can be designed in advance, and the on-the-spot Fast Installation of acoustics baffle device can be realized.
Need at audio amplifier to carry out, in the process of periodic maintenance or repairing, first sealing frame 401 being pulled down from baffle main body 102, by handle 1035, audio amplifier 104 and audio amplifier upper padding plate 1034 are pulled out from the perforate 1021 of baffle main body 102.Thus, even if the weight of audio amplifier is comparatively large, a people also easily can be shifted out baffle main body, realizes the Fast-Maintenance to audio amplifier.
By the structure of acoustics baffle device of the present utility model, achieve the acoustics baffle lightweight, processing can be designed in advance, and the on-the-spot Fast Installation of acoustics baffle device and the Fast-Maintenance to audio amplifier can be realized, all can implement in the low load building of the overwhelming majority.
More than being described the utility model in conjunction with concrete execution mode, but it will be apparent to those skilled in the art that these descriptions are all exemplary, is not the restriction to the utility model protection range.Those skilled in the art can make various variants and modifications according to spirit of the present utility model and principle to the utility model, and these variants and modifications are also in scope of the present utility model.
