Reel device with music play function

Abstract

A reel device with music play function includes a reel box, a music player and an earphone. The reel box has a shell and a reel element mounted in the shell. The music player is combined with the shell of the reel box. The earphone has a cable electrically connected with the music player and an audio output unit electrically connected with the cable. The reel element can reel in the cable of the earphone. Basing on the above structure, the present invention can provide a music play function and is convenient for carry, use and collection of the cable of the earphone.

1 . A reel device with music play function, comprising:
 a reel box having a shell and a reel element for providing an automatically retracting force mounted in the shell;   a music player combined with the shell of the reel box; and   an earphone having a cable electrically connected with the music player and an audio output unit electrically connected with the cable, the cable passing through and coiling round the reel element.   
     
     
         2 . The reel device as claimed in  claim 1 , wherein the shell has an axle pole and a limiting groove formed thereinside, and the reel element includes:
 a rotating plate, sleeving the axle pole and having a first groove annularly formed therein, an inclined guiding groove adjacent to and connected with the first groove, and a cut groove annularly formed therein and adjacent to the inclined guiding groove, wherein the cut groove is connected with the inclined guiding groove and the first groove;   a wind spring engaging with the axle pole and the rotating plate for providing an automatically retracting force for the rotating plate; and   a rolling ball rollably placed in the first groove, the inclined guiding groove or the cut groove and corresponding to the limiting groove.   
     
     
         3 . The reel device as claimed in  claim 2 , wherein the rotating plate has a collecting portion concavely formed in a side edge thereof and a through-hole connected with the collecting portion, and the cable passes through the through-hole and coils round the collecting portion. 
     
     
         4 . The reel device as claimed in  claim 2 , wherein the wind spring has two positioning ends, the axle pole has an axial slot for receiving one position end of the wind spring, and the rotating plate further has a positioning groove formed in a side edge thereof for receiving the other positioning end of the wind spring. 
     
     
         5 . The reel device as claimed in  claim 2 , wherein the wind spring is volute-shaped. 
     
     
         6 . The reel device as claimed in  claim 1 , wherein the music player is a MP3 player. 
     
     
         7 . The reel device as claimed in  claim 1 , further comprising a Bluetooth transceiver mounted in the shell. 
     
     
         8 . The reel device as claimed in  claim 7 , wherein the Bluetooth transceiver is electrically connected with the music player.
