[description of drawings]
Fig. 1 is a perspective exploded view of the present utility model.
[embodiment]
Below in conjunction with actual accompanying drawing, the utility model is further described:
As shown in Figure 1, the utility model is; A kind of portable loudspeaker box comprises that shell 1, loudspeaker 2, switch 3 and control circuit constitute, and loudspeaker 2 are arranged in the shell 1, are preferably disposed on shell 1 bottom, in addition in the lower end of loudspeaker 2; A bottom end cover can also be set, be used to protect loudspeaker 2, make the outward appearance of audio amplifier more attractive in appearance simultaneously. be provided with the sub-cavity 5 of storage battery cavity 4 and audio input end in the described shell 1, be respectively applied for and deposit storage battery 9 and audio input end 10.The top of shell 1 is provided with the upper end cover 6 that matches with shell 1 upper surface, and the top of upper end cover 6 is provided with the connecting hole 8 that is used to articulate noose 7, and this hole is generally through hole, can connect lanyard 7 by the structure that hook or link are set equally.Also be provided with storage battery 9 in the described storage battery cavity 4, the effect of upper end cover 6 mainly is to change among storage battery 9 and the taking-up audio input end 10 insertion mp3 to pick up audio signal, and when not using audio amplifier, above-mentioned audio input end 10 put back in the audio amplifier deposit.Storage battery 9 mainly can adopt common dry cell and rechargeable battery all can, this storage battery 9 is electrically connected with loudspeaker 2 and control circuit.
