Abstract

An earbud audio device includes a housing, a speaker component and a cushion, wherein the speaker component forms the tip of the earbud upon which the cushion may be situated. The speaker component is mechanically coupled to the earbud housing in a manner that allows the cushion to be coupled thereto, the speaker component and tip able to be partially inserted into a user'"'"'s ear canal during use. The speaker component may be formed with a flange extending outward to provide a support for mechanically coupling the speaker component to the housing. The speaker component and housing may in some instances be mechanically coupled together as two threaded components.

Claims

1. An earbud comprising:

a housing;

a speaker component having a proximal end mechanically coupled to a distal end of the housing; and

a cushion formed with an aperture fitted to an exterior portion of the speaker component;

wherein the speaker component forms a tip of the earbud, a portion of the tip extending beyond the housing in at least one direction,

wherein the speaker component has a first flange at or near the proximal end of the speaker component, the first flange extending outward from the proximal end of the speaker component,

wherein the first flange is mechanically coupled to the distal end of the housing such that the speaker component is secured in a fixed position relative to the housing, and

wherein the first flange of the speaker component is flexibly coupled with the housing such that the speaker component can be bent at a first angle relative to the housing.

2. The earbud of claim 1, wherein the first flange is mechanically coupled to an exterior wall of the distal end of the housing with an adhesive substance.

3. The earbud of claim 1, wherein the first flange is mechanically coupled to an interior wall of the distal end of the housing with an adhesive substance, the remainder of the speaker component being disposed within and projecting through an aperture formed at the distal end of the housing.

4. The earbud of claim 1, wherein the speaker component is coupled to the housing such that a longitudinal axis of the speaker component is situated at a non-zero angle relative to a longitudinal axis of the housing.

5. The earbud of claim 1, wherein an exterior of the speaker component maintains a substantially cylindrical shape, and wherein a diameter of the speaker component does not exceed 6.1 millimeters.

6. The earbud of claim 1, wherein an exterior of the speaker component maintains a substantially cylindrical shape, and wherein a diameter of the speaker component is between 6.1 millimeters and 6.7 millimeters.

7. The earbud of claim 1, wherein the speaker component has a height dimension which does not exceed 6.1 millimeters and a width dimension which does not exceed 6.1 millimeters.

8. The earbud of claim 1, wherein the speaker component has a height dimension between 6.1 millimeters and 6.7 millimeters and a width dimension between 6.1 millimeters and 6.7 millimeters.

9. The earbud of claim 1, wherein the speaker component maintains a substantially non-cylindrical shape, and wherein a thickness of the speaker component does not exceed 6.1 millimeters.

10. The earbud of claim 1, wherein the speaker component maintains a substantially non-cylindrical shape, and wherein a thickness of the speaker component is between 6.1 millimeters and 6.7 millimeters.

11. The earbud of claim 1, wherein the cushion includes an aperture having dimensions that substantially match an outside radial profile of the speaker component.

12. The earbud of claim 1, wherein the cushion includes an aperture smaller in at least one dimension than an exterior of the speaker component when the cushion is not situated upon the speaker component, and

wherein the cushion is made of a material that can flexibly adapt such that the aperture substantially matches a portion of exterior of the speaker component when the cushion is situated upon the speaker component.

13. The earbud of claim 1, wherein the first flange of the speaker component is formed from a flexible material.

14. The earbud of claim 2, wherein the adhesive substance employed to couple the first flange to the exterior housing wall is a flexible adhesive substance such that the speaker component can be bent at a first angle relative to the housing.

15. The earbud of claim 3, wherein the adhesive substance employed to couple the first flange to the interior housing wall is a flexible adhesive substance such that the speaker component can be bent at a first angle relative to the housing.

16. The earbud of claim 1, wherein a longitudinal axis of the speaker component is substantially parallel to a longitudinal axis of the housing.

17. The earbud of claim 1, wherein

a portion of the speaker component is threaded at or near its proximal end,

the distal end of the housing forms an aperture, and

the housing wall along the boundary of the aperture is reciprocally threaded to receive the threaded portion of the speaker component.
