Patent ID: 8322018

Claim:
A method for manufacturing a speaker, comprising: providing a first roll element, and spreading the first roll element to be flat strip-shaped; cutting the first roll element into a plurality of sheet elements, wherein each of the sheet elements is a vibrating membrane; providing a second roll element, wherein the second roll element is a porous electrode having supporters; providing an inserting device to insert the sheet elements into a temporary storage device; spreading the second roll element to be flat strip-shaped; providing an extracting device to extract the sheet elements from the temporary storage device; placing the sheet elements on the flat strip-shaped second roll element; and combining the sheet elements with the second roll element to form a speaker unit wherein the step of providing the first roll element comprises: forming a vibrating membrane layer, wherein the vibrating membrane layer comprises a vibrating membrane and metal layer formed on a surface of the vibrating membrane; forming a frame structure having a plurality of grids on the metal layer of the vibrating membrane layer; and performing a charge-maintaining process to the vibrating membrane layer to maintain charges on the vibrating membrane, so as to form the first roll element.
