Method of attaching a diaphragm to a frame for a planar loudspeaker

A method of coupling a diaphragm to a structure of an electro-dynamic loudspeaker, comprising:

• providing a 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 to position the diaphragm in a non-tensioned state;
• 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.
