Abstract

The earphone cord winder allows the cord of an earphone device to be wound thereto in order to prevent damage due to excessive bending. The earphone cord winder has a body, first, second, and third protrusions formed around the body at intervals forming an upper cord groove and a lower cord groove, two receiving slots recessed on a first surface of the body, a plug groove recessed on a second surface of the body, a middle groove connecting the opposite sides of the first protrusion, a remote control groove communicating with the upper cord groove, two first recessions communicating with the two receiving slots respectively, at least one second recession recessed on a side of the second protrusion, and at least one third recession recessed on a side of the third protrusion and communicating with the plug groove.

Claims

1. An earphone cord winder comprising:

a body having a peripheral surface, a first surface and a second surface opposite to the first surface;

a first protrusion formed around the peripheral surface of the body and having two sides opposite to each other;

a second protrusion formed around the peripheral surface of the body and having a side;

a third protrusion formed around the peripheral surface of the body and having a side, with the second protrusion between the first protrusion and the third protrusion, wherein interval spaces are formed between the first protrusion, the second protrusion and the third protrusion;

an upper cord groove formed among the body, the first protrusion and the second protrusion;

a lower cord groove formed among the body, the second protrusion and the third protrusion;

two receiving slots recessed on the first surface of the body;

a plug groove recessed on the second surface of the body;

a middle groove recessed on the first surface of the body between the two receiving slots and connecting the opposite sides of the first protrusion;

a remote control groove recessed on the peripheral surface of the body and communicating with the upper cord groove;

two first recessions recessed on one side of the first protrusion inwardly to the body and communicating with the two receiving slots respectively;

at least one second recession recessed on one side of the second protrusion; and

at least one third recession recessed on one side of the third protrusion inwardly to the body and communicating with the plug groove.

2. The earphone cord winder as claimed in claim 1, wherein:

the body is cubical and has four corners on the peripheral surface;

the first surface and the second surface are formed on a top and a bottom of the body respectively; and

the four corners on the peripheral surface of the body are rounded corners.

3. The earphone cord winder as claimed in claim 2, wherein the first protrusion, the second protrusion and the third protrusion are parallel with one another.

4. The earphone cord winder as claimed in claim 3, wherein the first protrusion, the second protrusion and the third protrusion are flush with one another.

5. The earphone cord winder as claimed in claim 4, wherein the two receiving slots are symmetrical.

6. The earphone cord winder as claimed in claim 5, wherein the at least one second recession comprises two second recessions.

7. The earphone cord winder as claimed in claim 6, wherein the at least one third recession comprises two third recessions.

8. The earphone cord winder as claimed in claim 2, wherein the first protrusion, the second protrusion and the third protrusion are flush with one another.

9. The earphone cord winder as claimed in claim 2, wherein the two receiving slots are symmetrical.

10. The earphone cord winder as claimed in claim 2, wherein the at least one second recession comprises two second recessions.

11. The earphone cord winder as claimed in claim 1, wherein the first protrusion, the second protrusion and the third protrusion are parallel with one another.

12. The earphone cord winder as claimed in claim 11, wherein the first protrusion, the second protrusion and the third protrusion are flush with one another.

13. The earphone cord winder as claimed in claim 12, wherein the two receiving slots are symmetrical.

14. The earphone cord winder as claimed in claim 13, wherein the at least one second recession comprises two second recessions.

15. The earphone cord winder as claimed in claim 14, wherein the at least one third recession comprises two third recessions.

16. The earphone cord winder as claimed in claim 1, wherein the first protrusion, the second protrusion and the third protrusion are flush with one another.

17. The earphone cord winder as claimed in claim 1, wherein the two receiving slots are symmetrical.

18. The earphone cord winder as claimed in claim 1, wherein the at least one second recession comprises two second recessions.
