Abstract
The utility model relates to a sound box bracket with a lifting mechanism, which belongs to the technical field of mechanical devices. The sound box bracket is characterized in that a lifting mechanism adopting a hydraulic linkage device is arranged between a base and each bracket. A take-up pulley is arranged between every two brackets through a shaft and a bearing. The sound box bracket has simple structure and convenient use. The use height of the sound box can be manually adjusted in a certain range, so that the sound field effect is very uniform.
Description
One, technical field
The utility model relates to a kind of support that raises and reduce audio amplifier, and specifically a kind of sound box bracket that has elevating mechanism belongs to mechanical device manufacturing technology field.
Two, background technology
Opera theatre troupe all have every year the performance of performing active many times, particularly large-scale theatre troupe all to relate to audio amplifier put angle with the height, this point is extremely important, it directly affects acoustics and performing quality.
At present, still be open-air mobile stage performance no matter at indoor stage, audio amplifier all is placed on the support of level altitude, and its audio amplifier height can't be regulated.And stage performance in the open air, different landform and the sizes in performance place, and spectators' the distribution that how much reaches shape, the capital produces different influences to performance, the situation more complicated in open-air performance place, reach high-quality performance, to the quality of audio amplifier and position of putting and very strictness of requirement for height.Facts have proved: putting of audio amplifier should be above the ground level more than 2 meters, the angle of entablature both sides audio amplifier is not greater than 45 degree yet, can avoid producing sound feedback like this, correct audio amplifier putting position can make the sound reinforcement system sound field even, can improve the sound pressure level listening zone, can fully obtain the direct sound wave of audio amplifier, play a multiplier effect.All there is relatively good locomotive function our its position of putting of employed audio amplifier now, but can not regulate in certain scope the height of audio amplifier, place the optimum efficiency that audio amplifier just can not reach performance like this, the putting position of audio amplifier is very important for replaying bass performance and whole structure.
Three, utility model content
The purpose of this utility model is can't regulate in order to solve existing sound box bracket height, makes the sound reinforcement system sound field inhomogeneous, and the dynamic sound equipment of audio amplifier can not get a desired effect, thereby proposes a kind of new technical scheme.
For achieving the above object, the utility model solves its designing technique defective and adopts following technical scheme to be:
A kind of sound box bracket that has elevating mechanism, it is to be made of audio amplifier frame, support and base, is provided with elevating mechanism between base and support; Between support and support, be provided with take-up pulley by axle and bearing.
The elevating mechanism that is provided with between base and each support is a hydraulicefficiency elevation structure, and the elevating mechanism that is provided with between each support and base is the hydraulic pressure linkage.
The advantage that the utility model is compared with prior art had is: simple in structure, easy to use, the sound box bracket height can artificially can be regulated in certain scope, by regulating the audio amplifier height, can make sound field effect very even.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic diagram of the utility model.
Five, embodiment
Now with specific embodiment the utility model is described in further details in conjunction with the accompanying drawings:
A kind of sound box bracket that has elevating mechanism, it is to be made of audio amplifier frame 1, four supports 2 and base 5, be respectively equipped with elevating mechanism 4 between base 5 and four supports 2, and the elevating mechanism 4 that is provided with between each support 2 and base 5 is the hydraulic pressure linkage.Between support 2 and support, be provided with take-up pulley 3 and be used to collect power line by axle and bearing.
During use, audio amplifier is placed on the audio amplifier frame 1, tramps with one's feet and step on pressurizing valve 6 elevating mechanism 4 is slowly raise, stop pressurization when arriving predetermined altitude, power line on the audio amplifier and the acoustic controller on the stage are electrically connected and can use.Can control elevating mechanism 4 as required, audio amplifier is placed on the best height, can fully represent stage sound effect.
