Flexible earphone cover
The flexible earphone cover has a flexible main body and a flexible ear cone that extends from the main body. The flexible main body is configured to substantially encase a portion of an earphone. The flexible main body defines an internal cavity for receiving the earphone. It also defines a first opening at a side of the cavity for receiving the earphone there-through. The flexible main body defines a second opening at a side of the cavity. The second opening is smaller than the first opening. Finally, the flexible main body defines a third opening at a side of the cavity. The third opening is smaller than the first opening and the second opening. The flexible ear cone defines a converging passageway from the second opening to an exit configured to direct sound into an ear canal of an ear of a user.
1. A flexible earphone cover, comprising:
a flexible main body configured to substantially encase a portion of an earphone, wherein the flexible main body defines:
an internal cavity for receiving the earphone;
a first opening at a side of the cavity for receiving the earphone there-through;
a second opening at a side of the cavity, the second opening being smaller than the first opening; and
a third opening at a side of the cavity, the third opening being smaller than the first opening and the second opening, wherein the main body defines no other holes therein;
a flexible ear cone extending from the main body, wherein the flexible ear cone defines:
a converging passageway from the second opening to an exit configured to direct sound into an ear canal of a user; and
multiple substantially parallel slits at the exit.
2. The flexible earphone cover of claim 1 , wherein an angle between a longitudinal axis that extends through a center of the ear cone and a longitudinal axis that extends through a center of the first opening is between about 55 degrees and about 80 degrees.
3. The flexible earphone cover of claim 1 , wherein the third opening is configured to pass sound from a treble hole in the earphone into the ear of the user.
4. The flexible earphone cover of claim 1 , wherein the third opening is configured to pass sound in a treble range of frequencies into the ear of the user.
5. The flexible earphone cover of claim 1 , wherein an entire outer surface of the earphone cover is substantially smooth with no sharp edges.
6. The flexible earphone cover of claim 1 , wherein the ear cone comprises three substantially parallel slits, where the middle slit is substantially longer than the other two slits.
7. The flexible earphone cover of claim 1 , wherein the main body is configured not to cover any holes formed in the earphone.
8. The flexible earphone cover of claim 1 , wherein the third opening is formed at an opposite side of the main body to the first opening.
9. The flexible earphone cover of claim 8 , wherein the third opening offset from a longitudinal axis formed through the first opening.
10. The flexible earphone cover of claim 9 , wherein the third opening has a stadium shape.
11. The flexible earphone cover of claim 9 , wherein the third opening has a shape that matches the shape of a corresponding hole formed in the earphone.
12. The flexible earphone cover of claim 1 , wherein the main body and ear cone are integrally formed out of a material having a uniform thickness.
13. The flexible earphone cover of claim 1 , wherein the main body and ear cone are integrally formed out of a material having a thickness that is thicker near the first opening than the remainder of the main body and ear cone.
14. The flexible earphone cover of claim 1 , wherein the main body and ear cone are integrally formed out of a material having a thickness that is thinner near the first opening than the remainder of the main body and ear cone.
15. The flexible earphone cover of claim 1 , wherein the earphone cover is made from an injection molded flexible elastomer.
16. The flexible earphone cover of claim 1 , wherein the earphone cover is made from an elastomer that does not substantially lose its grip when wet.
17. The flexible earphone cover of claim 1 , wherein the earphone cover is made from an elastomer that is injection molded into an injection gate within the internal cavity.
18. The flexible earphone cover of claim 1 , wherein the first opening is an oval or oblong.
19. The flexible earphone cover of claim 1 , wherein the main body has a logo integrally formed therein.
20. A method of making a flexible earphone cover comprising:
integrally forming a flexible main body and ear cone by injection molding a flexible elastomer to form:
(i) the main body defining:
an internal cavity for receiving an earphone;
a first opening at a side of the cavity for receiving the earphone there-through;
a second opening at a side of the cavity, the second opening being smaller than the first opening; and
a third opening at a side of the cavity, the third opening being smaller than the first opening and the second opening, wherein the main body defines no other holes therein; and
(ii) the flexible ear cone that extends from the main body and defines a converging passageway from the second opening to an exit having multiple parallel slits.
