  • Publication number: 20100325873
    Abstract: A method for manufacturing a stator (24) for an electrostatic loudspeaker in which at least a part of a structure (28) for forming the stator (24) is moulded from an electrically insulating material. This structure (28) may be a frame of the stator. To complete the stator (24), electrically conductive portions (30) are combined with the moulded structure to form a complete structure that includes an electrically conductive grid (29). The electrically conductive portions (30) may be a preformed grid (29). The frame (28) and the grid (29) may be pressfitted together. Alternatively the moulded structure may be electrically conductive, and electrically insulating portions may be combined with it to form a complete stator. Manufacture of electrostatic loudspeaker stators using a moulding process allows for relatively low cost production methods that can repeatedly achieve a required high degree of accuracy.

This structure (28) may be a frame of the stator. To complete the stator (24), electrically conductive portions (30) are combined with the moulded structure to form a complete stricture that includes an electrically conductive grid (29). The electrically conductive portions (30) may be a preformed grid (29). The frame (28) and the grid (29) may be press-fitted together. Alternatively the moulded structure may be electrically conductive, and electrically insulating portions may be combined with it to form a complete stator.
