Patent ID: 7716808

Claim:
A method of coupling a diaphragm to a structure of an electro-dynamic loudspeaker, comprising: providing the diaphragm having an electrical circuit coupled to a film, where the diaphragm includes a center portion surrounded by a perimeter portion; providing a clamp, where the clamp is selectively moveable from an opened position to a closed position; positioning the diaphragm within the clamp when the clamp is in the opened position; conforming the diaphragm to a substantially flat plane and in a non-tensioned state by positioning one side of the diaphragm adjacent to a platen and by drawing a vacuum through the platen to cause the diaphragm to conform to a shape of the platen; moving the clamp to the closed position and clamping the perimeter portion of the diaphragm thereby temporarily fixing the diaphragm in the non-tensioned state; displacing the center portion of the diaphragm to produce a predetermined tension in the film; applying an adhesive curable by exposure to radiation to at least one of the diaphragm and a frame; and irradiating the adhesive to couple the diaphragm to the frame while the predetermined tension is maintained.
