Unit body housing in a speaker system
Certain embodiments include an injection-molded portable speaker apparatus including a portable speaker housing with an opening formed on the surface, a flexible inverted speaker surround including an inner perimeter and an outer perimeter, where the outer perimeter is coupled to an outer edge of the opening of the housing, and a diaphragm coupled to the inner perimeter of the flexible surround such that the diaphragm is suspended within the opening of the housing, where the flexible surround and diaphragm form a speaker passive, and where the speaker housing and the flexible surround form a continuous unitized body. The injection molding process for the continuous unitized body can be a two-shot process, where the first shot forms the speaker housing, and the second shot forms the flexible surround, which may further over-mold the diaphragm, such that the diaphragm is part of the continuous unitized body.
1. A portable speaker apparatus comprising:
a speaker housing having a surface, the speaker housing including an opening formed on the surface of the speaker housing;
a flexible surround including an inner circumference and an outer circumference, the outer circumference coupled to an outer edge of the opening of the speaker housing; and
a diaphragm coupled to the inner circumference of the flexible surround such that the diaphragm is suspended within the opening of the speaker housing,
wherein the flexible surround and diaphragm form a speaker passive, and
wherein the speaker housing and the flexible surround form an integrated, continuous, and unitized body formed via a multi-shot injection molding process such that there are no seams between the speaker housing and the flexible surround, and the diaphragm is coupled to the inner circumference of the flexible surround via an over-molding process.
2. The portable speaker apparatus of claim 1 wherein the flexible surround is an inverted surround.
3. The portable speaker apparatus of claim 1 wherein the flexible surround is comprised of liquid silicone rubber (LSR) or thermoplastic polyurethane (TPU).
4. The portable speaker apparatus of claim 1 wherein the speaker housing is comprised of a polycarbonate.
5. The portable speaker apparatus of claim 1 wherein the integrated, continuous, and unitized body is injection molded in a multi-shot process, wherein a first shot of the multi-shot process forms the speaker housing, and wherein a second shot of the multi-shot process forms the flexible surround and over-molds the diaphragm, such that the diaphragm is part of the integrated, continuous, and unitized body.
6. The portable speaker apparatus of claim 1 wherein the housing is formed in one of a cylindrical shape, rectangular shape, square shape, oval shape, pill shape, saucer shape, or spherical shape.
