Abstract

Headphone eartips with internal support components and methods for making the same are provided. At least one support component may provide specific amounts and types of rigidity at specific portions of an inner eartip body defining an inner eartip space that transmits sound to an eardrum when an eartip subassembly is positioned within an ear canal, such that the eartip subassembly may ensure an effective sound path while also at least partially conforming to various ear canal geometries.

First claim

What is claimed is:

1. An earpiece that is operative to be at least partially positioned within an ear canal, the earpiece comprising:
an eartip subassembly comprising:
an inner eartip body comprising:
an inner eartip front end with an inner eartip front opening through the inner eartip front end;
an inner eartip back end with an inner eartip back opening through the inner eartip back end;
an inner eartip interior surface extending between the inner eartip front opening and the inner eartip back opening for defining an inner eartip space; and
an inner eartip exterior surface extending about the inner eartip interior surface between the inner eartip front end and the inner eartip back end;

an outer eartip body that is operative to deform when the earpiece is at least partially positioned within the ear canal, the outer eartip body comprising:
an outer eartip front end with an outer eartip front opening through the outer eartip front end, wherein the outer eartip front end is coupled to the inner eartip front end for at least partially aligning the inner eartip front opening and the outer eartip front opening;
an outer eartip back end with an outer eartip back opening through the outer eartip back end;
an outer eartip interior surface extending between the outer eartip front opening and the outer eartip back opening for defining an outer eartip space; and
an outer eartip exterior surface extending about the outer eartip interior surface between the outer eartip front end and the outer eartip back end; and

an internal support subsystem comprising an internal support component; and

a transducer subassembly that is operative to emit sound into the inner eartip space, wherein:
the internal support component comprises at least one of a spring or a plurality of rings;
the internal support component contacts at least a portion of the inner eartip body;
the internal support component extends at least partially about the inner eartip space;
the internal support component is operative to retain the transducer subassembly in a position with respect to the inner eartip space; and
the internal support component is operative to ensure that a cross-sectional area of the inner eartip space exists along at least a portion of the length of the inner eartip space when the earpiece is at least partially positioned within the ear canal.

2. The earpiece of claim 1 , wherein:
the inner eartip body comprises silicone; and
the internal support component comprises metal.

3. The earpiece of claim 1 , wherein at least a portion of the internal support component is positioned about and against the inner eartip exterior surface.

4. The earpiece of claim 1 , wherein at least a portion of the internal support component is positioned within the inner eartip space against the inner eartip interior surface.

5. The earpiece of claim 1 , wherein at least a portion of the internal support component is positioned within the inner eartip body between the inner eartip exterior surface and the inner eartip interior surface.

6. The earpiece of claim 1 , wherein:
the internal support subsystem comprises a plurality of rings; and
each ring of the plurality of rings extends at least partially about the inner eartip space at a different position along the length of the inner eartip space.

7. An earpiece that is operative to be at least partially positioned within an ear canal, the earpiece comprising:
an eartip subassembly comprising:
an inner eartip body comprising:
an inner eartip front end with an inner eartip front opening through the inner eartip front end;
an inner eartip back end with an inner eartip back opening through the inner eartip back end;
an inner eartip interior surface extending between the inner eartip front opening and the inner eartip back opening for defining an inner eartip space; and
an inner eartip exterior surface extending about the inner eartip interior surface between the inner eartip front end and the inner eartip back end;

an outer eartip body that is operative to deform when the earpiece is at least partially positioned within the ear canal, the outer eartip body comprising:
an outer eartip front end with an outer eartip front opening through the outer eartip front end, wherein the outer eartip front end is coupled to the inner eartip front end for at least partially aligning the inner eartip front opening and the outer eartip front opening;
an outer eartip back end with an outer eartip back opening through the outer eartip back end;
an outer eartip interior surface extending between the outer eartip front opening and the outer eartip back opening for defining an outer eartip space; and
an outer eartip exterior surface extending about the outer eartip interior surface between the outer eartip front end and the outer eartip back end; and

an internal support subsystem comprising an internal support component, wherein:
the internal support component contacts at least a portion of the inner eartip body;
the internal support component extends at least partially about the inner eartip space;
the internal support component is operative to ensure that a cross-sectional area of the inner eartip space exists along at least a portion of the length of the inner eartip space when the earpiece is at least partially positioned within the ear canal;
the internal support subsystem comprises a plurality of internal support components comprising the internal support component and at least one other internal support component;
each internal support component of the plurality of internal support components extends at least partially about the inner eartip space at a different position along the length of the inner eartip space; and
each internal support component of the plurality of internal support components comprises a metal ring extending about at least 75% of the inner eartip space.

8. The earpiece of claim 7 , wherein the plurality of internal support components comprises at least five internal support components.

9. The earpiece of claim 1 , wherein the internal support component comprises a plurality of rings, and wherein at least one of the rings of the plurality of rings comprises a metal ring extending about at least 75% of the inner eartip space.

10. The earpiece of claim 1 , wherein the internal support component comprises a spring.

11. The earpiece of claim 10 , wherein the spring winds a plurality of times about the inner eartip space and along at least the portion of the length of the inner eartip space.

12. The earpiece of claim 11 , wherein at least a portion of the internal support component is positioned within the inner eartip body between the inner eartip exterior surface and the inner eartip interior surface.

13. The earpiece of claim 12 , wherein the internal support component is operative to change the cross-sectional area of the inner eartip space at a first a portion of the inner eartip space along the length of the inner eartip space when the inner eartip body is twisted with respect to another component of the earpiece about an axis of the inner eartip space.

14. The earpiece of claim 10 , wherein:
a first portion of the spring is coupled to the inner eartip body; and
a second portion of the spring is coupled to the transducer subassembly.

15. The earpiece of claim 14 , wherein:
the spring comprises a plurality of coils;
the first portion of the spring comprises at least a portion of the plurality of coils;
the at least a portion of the plurality of coils winds at least one time about the inner eartip space and along at least the portion of the length of t
