Abstract

A joint speaker surround and gasket. The speaker surround of the joint speaker surround and gasket is formed of a surround material and has an inner edge defining a speaker cone aperture shaped to match a speaker cone and an outer edge portion shaped to match a housing. The gasket of the joint speaker surround and gasket is formed of a gasket material. The gasket is integrally bonded to the outer edge portion of the speaker surround.

Claims

1. A joint speaker surround and gasket, comprising:

a speaker surround formed of a surround material, the speaker surround having an inner edge defining a speaker cone aperture shaped to match a speaker cone and an outer edge portion shaped to match a housing; and

a gasket integrally bonded to the outer edge portion of the speaker surround, the gasket molded of a gasket material.

2. The joint speaker surround and gasket of claim 1, wherein the surround material is a flexible material.

3. The joint speaker surround and gasket of claim 2, wherein the speaker surround has a structure in a plane perpendicular to a plane of the speaker cone aperture such that the inner edge of the speaker surround is elastically movable relative to the outer edge portion in a direction normal to the speaker cone aperture.

4. The joint speaker surround and gasket of claim 3, wherein:

the speaker surround has a width between the outer edge portion and the inner edge and a thickness in the direction normal to the plane of the speaker cone aperture; and

the width is significantly greater than the thickness.

5. The joint speaker surround and gasket of claim 3, wherein:

the gasket material is elastically compressible; and

a thickness of the gasket in a direction normal to the plane of the speaker cone aperture is greater than a predetermined maximum travel of the inner edge of the speaker surround relative to the outer edge portion.

6. The joint speaker surround and gasket of claim 5, wherein the gasket material is one of:

rubber;

silicone;

or elastomer.

7. The joint speaker surround and gasket of claim 2, wherein the surround material is one of:

rubber;

silicone;

plastic;

metal;

cloth;

paper;

foam rubber;

a plastic foam;

or a composite material including fibers and a resin.

8. A method of manufacture of a joint speaker surround and gasket, the method comprising:

forming a speaker surround from a speaker surround blank, the speaker surround including an outer edge portion and an inner edge defining a speaker cone aperture; and

molding a gasket to the outer edge portion of the speaker surround such that the gasket is integrally bonded to the speaker surround.

9. The method of claim 8, wherein forming the speaker surround from the speaker surround blank includes at least one of:

stamping the speaker surround blank to form one or more of;

the outer edge portion of the speaker surround;

the inner edge of the speaker surround;

or

structure of the speaker surround normal to the speaker cone aperture;

die cutting the speaker surround from the speaker surround blank to form one or more of;

an outer edge surrounding the outer edge portion of the speaker surround;

or

the inner edge of the speaker surround;

heat forming the speaker surround blank to form structure of the speaker surround normal to the speaker cone aperture;

plastically deforming the speaker surround blank to form structure of the speaker surround normal to the speaker cone aperture;

etching the speaker surround blank;

or

coating the speaker surround blank or the speaker surround.

10. The method of claim 8, wherein:

the speaker surround blank includes a carrier and a speaker surround film formed on the carrier; and

forming the speaker surround from the speaker surround blank includes forming the speaker surround in the speaker surround film.

11. The method of claim 10, wherein forming the speaker surround from the speaker surround blank further includes separating the speaker surround formed in the speaker surround film from the carrier of the speaker surround blank.

12. The method of claim 10, wherein:

molding the gasket to the outer edge portion of the speaker surround includes molding the gasket to the outer edge portion of the speaker surround formed in the speaker surround film such that the gasket is integrally bonded to the speaker surround; and

the method further comprises;

separating the joint speaker surround and gasket from the carrier of the speaker surround blank.

13. The method of claim 8, wherein molding the gasket to the outer edge portion of the speaker surround includes:

placing the speaker surround into an injection molding cavity for the gasket such that the outer edge portion of the speaker surround forms a portion of a surface of the injection molding cavity;

injecting gasket material to fill the injection molding cavity;

setting the gasket material to form the gasket such that the gasket is integrally bonded to the speaker surround; and

removing the joint speaker surround and gasket from the injection molding cavity.

14. The method of claim 8, wherein molding the gasket to the outer edge portion of the speaker surround includes:

placing the outer edge portion of the speaker surround on a first portion of a compression molding cavity for the gasket;

depositing a predetermined amount of gasket material in the first portion of the compression molding cavity on the outer edge portion of the speaker surround;

compressing a second portion of the compression molding cavity into the deposited gasket material to form the gasket such that the gasket is integrally bonded to the speaker surround; and

removing the joint speaker surround and gasket from the compression molding cavity.

15. The method of claim 8, wherein:

the speaker surround is formed of a speaker surround material;

the gasket is formed of a gasket material; and

molding the gasket to the outer edge portion of the speaker surround includes supplying one of;

a predetermined amount of heat in the molding process, the predetermined amount of heat being sufficient to bond the speaker surround material to the gasket material;

a predetermined amount of pressure in the molding process, the predetermined amount of pressure being sufficient to bond the speaker surround material to the gasket material;

a predetermined combination of heat and pressure in the molding process, the predetermined combination of heat and pressure being sufficient to bond the speaker surround material to the gasket material;

or

a predetermined amount of solvent, the predetermined amount of solvent being sufficient to bond the speaker surround material to the gasket material.

16. A method of manufacture of a joint speaker surround and gasket, the method comprising:

molding a gasket to a gasket portion of a speaker surround blank; and

forming a speaker surround from the speaker surround blank, the speaker surround including an outer edge portion and an inner edge defining a speaker cone aperture, the speaker surround being formed such that the outer edge portion of the speaker surround corresponds to the gasket portion of the speaker surround blank;

wherein the gasket is integrally bonded to the outer edge portion of the speaker surround.

17. The method of claim 16, wherein one of:

molding the gasket to the gasket portion of the speaker surround blank includes integrally bonding the gasket to the gasket portion of the speaker surround;

or

forming the speaker surround from the speaker surround blank includes integrally bonding the gasket to the outer edge portion of the speaker surround.

18. The method of claim 16, wherein molding the gasket to the gasket portion of the speaker surround blank includes one of:
