Abstract
An integrated voice coil and cone assembly includes a cone assembly having a top diaphragm skin and a bottom diaphragm skin with a space between the top diaphragm skin and bottom diaphragm skin. The integrated voice coil and cone assembly also includes a voice coil configured to engage the cone assembly along a perimeter edge thereof and an adhesive material placed between the top diaphragm skin and bottom diaphragm skin such that the adhesive material fills all of the space between the top and bottom diaphragm skins. The adhesive material also bonds the top diaphragm skin, bottom diaphragm skin, and voice coil into a single, integrated unit.
Claims17
An integrated voice coil and cone assembly comprising:
- a cone assembly having a top diaphragm skin and a bottom diaphragm skin with a space between the top diaphragm skin and bottom diaphragm skin;
- a voice coil configured to engage the cone assembly along a perimeter edge thereof;
- and
- an adhesive material placed between the top diaphragm skin and bottom diaphragm skin such that the adhesive material fills all of space between the top and bottom diaphragm skins, and bonds the top diaphragm skin, bottom diaphragm skin, and cone assembly into a single unit.
The integrated voice coil and cone assembly of claim 10, wherein the non-round shape is obround, square or polygonal.
A method of manufacturing an integrated voice coil and cone assembly, the method comprising:
- aligning an interior surface of a ring-shaped voice coil with a perimeter edge of a cone assembly;
- attaching the voice coil to the perimeter edge of the cone assembly, the cone assembly comprising a top diaphragm skin and bottom diaphragm skin;
- wherein attaching the voice coil to the perimeter edge of the cone assembly comprises filling an entire space between the top diaphragm skin and bottom diaphragm skin with an adhesive, which bonds the top diaphragm skin, bottom diaphragm skin, and voice coil into a single, integral unit.
A method of manufacturing a cone assembly, the method comprising:
- providing either a capped former or a top diaphragm skin;
- providing a bottom diaphragm skin;
- and
- installing a settable foam between the bottom diaphragm skin and either the capped former or the top diaphragm skin, thereby forming the cone assembly.
