Backpack structure

Abstract

A backpack primarily includes a backpack housing in which two straps are connected thereto. A speaker is buried in each of the two straps with meshes being disposed thereon. Two first pocket bodies are disposed at suitable locations from the bottom of each of the two speakers. An amplifier is then disposed in an interior of the backpack, so that the amplifier is connected to the speaker buried inside the backpack housing and the straps and further connected to a plug emerged from a top of one of the pocket bodies. Therefore, playing devices such as MP3, radios, etc. can be placed in the pocket bodies and music and songs can be played over the two speakers, by means of the conductive wires and the amplification of the amplifier.

1 . A backpack structure comprising: 
 a backpack housing having two straps are disposed on a front thereof; two speakers are disposed at suitable locations from a top of the two straps with meshes being disposed on the speakers; a first pocket body is disposed at a suitable location from a bottom of the speaker; a second pocket body is disposed on an interior of the backpack housing to hold an amplifier, which is then connected to the speakers buried in a backpack cloth interlayer and an interlayer of the straps, and further connected to a plug emerged from a top of one of the first pocket bodies; a playing device is placed into the other of the first pocket bodies, and connected to the plug therefrom, such that signals emitted from the playing device can be transmitted by the conducting wires and amplified by the amplifier, thereby receiving and playing music and songs over the speakers.    
   
   
       2 . The backpack structure as claimed in  claim 1 , wherein a top cover is disposed on a top of each of the first pocket bodies formed on the straps and the second pocket body disposed on the interior of the backpack housing respectively.  
   
   
       3 . The backpack structure as claimed in  claim 1 , wherein a wider interlayer is disposed in the backpack housing to hold objects such as a portable computer, a notebook, etc.
