Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, and provides one to be convenient for carrying and the adjustable Portable earphone of line length.Specific as follows:
A kind of Portable earphone, comprise headband, earmuff, earphone cord, headband two ends are connected to earmuff, are provided with coiling in earmuff, are plenum chamber in coiling, the two ends of coiling are installed with rotating shaft respectively, and spring mountings is through the rotating shaft of inner side and coiling and be arranged in the plenum chamber of coiling; The chamber interior of coiling is provided with spring coil, and one end of spring coil is fixed on coiling chamber interior through stator, and the other end of spring coil is connected with spring mountings.Described coiling is cylindrical.
Rotating shaft outer setting has sleeve, is fixedly connected with outside sleeve through support bar, and support bar is fixed on earmuff inside, and rotating shaft does not contact with sleeve.
Be connected with disk through earmuff outside rotating shaft, disk centre is provided with the collar, and the collar is equidistant is outward provided with at least 8 cylinder bolts.
Coiling outside is wound with earphone cord, and earphone cord after coiling is repeatedly wound around, then is connected with circuit board after the gap between support bar with rotating shaft is fixing, and earphone cord is connected with the hole that amplifies through circuit board again.The place that left and right earphone cord crosses is provided with volume knob, and afterbody is provided with headset plug.
When adopting said structure, what be positioned at coiling inside can realize elongation and the shortening of earphone cord by Compression and Expansion spring coil device by the Tension and Compression of spring, coiling outside is wound with earphone cord, can realize the smooth winding of earphone cord and loosen; Spring mountings can realize the fixing of earphone internal structure, spring mountings and stator achieve can Compression and Expansion spring coil two ends fixing, fixing of the rotating shaft that fixed muffle realizes, prevents rotating shaft from rocking, and the collar on disk is enclosed within cylinder bolt and realizes the fixing of earphone cord length; Support bar realizes the support of countershaft, and they sup-port is in the below of fixed muffle, and fixed muffle is enclosed within the outside of rotating shaft, and support bar achieves the support of countershaft; The cylindrical sleeves that earphone cord is arranged near the place of earmuff shell can realize rectilinear motion when earphone cord elongation is shortened, and volume knob realizes the adjustment of volume; Headband realizes earphone fixing at head.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of Portable earphone, wherein, and 1. spring mountings, 2. stator, 3. spring coil, 4. rotating shaft, the 5. collar, 6. cylinder bolt, 7. fixed muffle, 8. support bar, 9. coiling, 10. earmuff, 11. cylindrical sleeves, 12. earphone cords, 13. circuit boards, 14. amplify hole, 15. volume knob, 16. Earphone joints, 17. headbands, 18. disks.
Embodiment
As shown in Figure 1, a kind of Portable earphone, comprise be positioned at that whole earmuff shell is inner most can the spring coil 3 of Compression and Expansion, spring coil 3 is arranged in the cavity in the middle of coiling 9, one end of spring coil 3 is connected with coiling 9 by stator 2, the top of coiling 9 is wound with earphone cord 12, and the both sides of coiling 9 are all connected with rotating shaft 4; Fixing spring part 1 is L shape bar, fixing spring part 1 one end is connected with spring coil 3 through rotating shaft 4, the other end is connected with earmuff 10 madial wall, the inner chamber of one end of spring coil 3 with coiling 9 is directly connected by stator 2, fixed muffle 7 is cylindrical cavities, and intermediate sleeve has rotating shaft 4, and does not contact with rotating shaft 4, fixed muffle 7 bottom is connected with support bar 8, and support bar 8 lower end is connected with earmuff 10 inner casing.
Be connected with disk 18 through earmuff 10 outside rotating shaft 4, disk 18 centre is provided with the collar 5, and the collar 5 is equidistant is outward provided with at least 8 cylinder bolts 6.
Coiling 9 outside is wound with earphone cord 12, and earphone cord 12 after coiling is wound around for more than 9 time, then is connected with circuit board 13 after the gap between support bar 8 with rotating shaft 4 is fixing, and earphone cord 12 is connected with the hole 14 that amplifies through circuit board 13 again.
When earphone cord 12 is pulled down, rotation followed by coiling 9, spring coil 3 is short by pulling-down, when earphone cord 12 moves certain position to, the collar 5 be positioned on disk 18 is enclosed within cylinder bolt 6, earphone cord 12 line length is fixed, when earphone cord 12 length is long, cylinder bolt 6 can be unclamped, spring coil 3 reverse rotation is stretched and is driven coiling 9 reverse rotation to make earphone cord 12 upwards shorten certain length, again the collar 5 is enclosed within function cylinder bolt 6 realizing regulating earphone cord 12 line length when shortening to suitable position, coiling 9 and spring coil 3 achieve elongation and the shortening of earphone cord 12.
Fixing spring part 1 and stator 2 achieve the fixing of spring coil 3, and make spring coil 3 can well realize extending and shrinking, fixed muffle 7 can realize the stable rotation of rotating shaft 4, finally realizes earphone cord 12 and extends stably and shrink.
