Abstract
A method of manufacturing a protection frame used in a miniature microphone is provided. In one embodiment, the method comprises the steps of: (1) preparing a substrate made of an insulating material with a prescribed thickness and a prescribed area; (2) forming a plurality of holes at prescribed intervals on the substrate; (3) forming a first metal shielding layer on the inner surface of each of the plurality of holes formed on the substrate; (4) filling an insulating material in the plurality of holes; (5) forming a plurality of extended portions on the surfaces of both sides of the substrate, each extended portion covering a part of the end face of the insulating material and the whole end face of the first metal shielding layer of a hole; (6) forming a cavity in each insulating material-filled hole, the caliber of each cavity being slightly smaller than the inner caliber of the corresponding extended portion formed in the above mentioned step (5); and (7) cutting the plurality of holes from the substrate to produce a collection of protection frames.
