Claims11
A method of manufacturing diaphragm assembly, comprising:
- providing a cone with at least one alignment feature at a peripheral edge thereof;
- providing a mounting tool comprising at least one cooperating fixing element, wherein the at least one alignment feature is aligned with the at least one cooperating fixing element respectively such that the cone is centered within an injection chamber;
- forming a surround at the peripheral edge of the cone by an injection molding process,
- wherein the at least one cooperating fixing element not only positions the cone during molding but also causes the surround, after molding, to include a recessed portion formed by the shape of the at least cooperating fixing element and located within the alignment feature, such that the recessed portion is structurally surrounded by the cone within the alignment feature, and the recessed portion and the surround are integrally formed from the same material through the injection molding process.
