Abstract
The utility model relates to an aluminum rear frame of a soundbox. The aluminum rear frame mainly comprises an aluminum box, a PCB (Printed Circuit Board), a quadrangular pressing strip, a spring steel pressing plate, a fastening screw and a heat radiating tube, wherein the fastening screw passes through circular holes in the spring steel pressing plate, the quadrangular pressing strip and the PCB and is matched with a screw hole in the aluminum box and fastened on the aluminum box. As the full-aluminum-alloy outer frame is adopted, the defect of insufficient heat radiation is overcome, the heat radiating cost and the cost of adding an iron box on the reverse surface are saved, the whole set of aluminum rear frame mold is high in molding and producing efficiency, the size accuracy is greatly improved, and the production efficiency and the quality stability of the aluminum rear frame are improved.
Description
Technical field
The utility model relates to the stereo set field, especially a kind of sound equipment aluminium after-frame that reaches heat radiation and sealing effectiveness that utilizes the aluminium frame to substitute can.
Background technology
At present, traditional sound equipment internal structure is all that pcb board is arranged on above can of sound equipment, because the shell fan thermal effect of irony is poor, is easy to cause the circuit of the inside to burn out because heating causes power tube and other spare and accessory parts thereof; And its structural strength after installing is poor, after the shock that is subject to external force and the vibrations of itself, is easy to make the structure of pcb board or the inside to come off, and damages the electronic component of the inside, brings many troubles in the process of using in to people.
The utility model content
Thermal effect is poor and the structure installation is insecure, the defective of intensity difference owing to fanning in order to overcome traditional acoustic structure, the utility model provides a kind of sound equipment aluminium after-frame, it is simple in structure, not only solved the not enough defective of heat radiation, and saved heat radiation cost and the sub-cost of reverse side increase can, improved the stability of production efficiency and product quality.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of sound equipment aluminium after-frame, mainly comprise aluminium box, pcb board, four jiaos of press strips, spring steel compressing tablet, holding screw, radiating tube, described holding screw passes the circular hole on spring steel compressing tablet, four jiaos of press strips, pcb board, screw hole coupling with on the aluminium box is fastened on the aluminium box.
Described pcb board is provided with five circular holes, and four corners and centre on four jiaos of press strips respectively are provided with a socle, totally five socles, and its length has been just pcb board and radiating tube gross thickness.
Five circular holes that five socles of described four jiaos of press strips pass pcb board withstand the inner surface of aluminium box.
Described four jiaos of press strips are provided with the spring steel compressing tablet, are used for pushing down four jiaos of press strips.
Described spring steel compressing tablet, four jiaos of press strips, pcb boards are provided with the circular hole of a holding screw slightly larger in diameter, and the aluminium box corresponding with it is provided with a screw hole that mates with holding screw.
Described radiating tube is fixed on pcb board, just is attached on the inner edge face of aluminium box after fixing.
The beneficial effects of the utility model are: sound equipment aluminium after-frame adopts all aluminium alloy housing, solved the not enough defective of heat radiation, save heat radiation cost and reverse side and increased the sub-cost of can, a whole set of aluminium after-frame mould molding, production efficiency is high, dimensional accuracy increases greatly, has improved the stability of production efficiency and product quality.
