Description
Technical field
The present invention relates to audio amplifier, be specifically related to a kind of band SD card data and read and charge function portable loudspeaker box.
Background technology
Nowadays, the portable loudspeaker box scope of application is more and more wider, in the time that needs are given outside charging of mobile devices, conventionally needs extra charging device, if band SD card data read functions, we can break away from the burden of wire harness, bring great convenience to us.
Summary of the invention
The object of this invention is to provide a kind of band SD card data and read and charge function portable loudspeaker box, this audio amplifier is to overcome the deficiencies in the prior art.
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is: a kind of band SD card data read and charge function portable loudspeaker box, it is characterized in that, it comprises audio amplifier body, power interface, switch, audio interface, control circuit board, lithium battery, loud speaker, operating key, standard USB seat, SD draw-in groove; In the embedded installation audio amplifier of described power interface body, switch is embedded to be arranged in audio amplifier body, audio interface is embedded to be arranged in audio amplifier body, the embedded audio amplifier body interior that is arranged on of operating key, control circuit board is arranged on audio amplifier body interior, and lithium battery is arranged on audio amplifier body interior, and loud speaker is arranged on audio amplifier body interior, standard USB seat is embedded to be arranged in audio amplifier body, and SD draw-in groove is embedded to be arranged in audio amplifier body.
Described audio amplifier body is aluminium material.
On described control circuit board, be furnished with power amplifier and charge-discharge circuit.
Described switch, audio interface, lithium battery, loud speaker, operating key are connected to control circuit board by wire.
Described audio interface is standard 3.5mm audio interface.
The adjustable sound size of described operating key, next song, last song, F.F. and retreat.
Described standard USB seat is connected on control circuit board by wire.
Described SD draw-in groove is connected to the power amplifier on control circuit board by wire.
Advantage of the present invention and good effect are: 1. easy to use and carry; 2. chargeable and external data reads conveniently.
Accompanying drawing explanation
Fig. 1 is with SD card data for one and reads and charge function portable loudspeaker box.
Fig. 2 regards routine backsight structural representation as shown in Fig. 1.
Wherein: 1, audio amplifier body, 2, loud speaker, 3, control circuit board, 4, switch, 5, operating key, 6, audio interface, 7, power interface, 8, lithium battery, 9, standard USB seat, 10, SD draw-in groove.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of band SD card data read and charge function portable loudspeaker box, and as Fig. 1, shown in Fig. 2, it comprises audio amplifier body 1, loud speaker 2, control circuit board 3, switch 4, operating key 5, audio interface 6, power interface 7, lithium battery 8, standard USB seat 9, SD draw-in groove 10; In the embedded installation audio amplifier of described power interface 7 body 1, switch 4 is embedded to be arranged in audio amplifier body 1, audio interface 6 is embedded to be arranged in audio amplifier body 1, embedded audio amplifier body 1 inside that is arranged on of operating key 5, control circuit board 3 is arranged on audio amplifier body 1 inside, lithium battery 8 is arranged on audio amplifier body 1 inside, loud speaker 2 is arranged on audio amplifier body 1 inside, standard USB seat 9 is embedded to be arranged in audio amplifier body 1, SD draw-in groove 10 is embedded to be arranged in audio amplifier body 1, forms band SD card data and reads and charge function portable loudspeaker box.
Concrete operations are as follows: first external power source is connect and is put in the power interface 7 being embedded in audio amplifier body 1, via the charging circuit on control circuit board 3, lithium battery 8 is charged, external sound source is linked into audio interface 6 or external data card is inserted in SD draw-in groove 10, open switch 4, after sound amplifies via the power amplifier on control circuit board 3, send from loud speaker 2 again, the adjustable sound size of operating key 5, next song, last song, F.F. and retreating, in the time that we need to give outside charging of mobile devices, only USB line need be inserted in standard USB seat 9.
In the present invention, as becoming row embodiment, audio amplifier body is aluminium material.Therefore the scope that the scope of the present invention limits with claims is as the criterion.
