Abstract
The utility model relates to a rolling device of an electret microphone, comprising a machine frame, a machine head, a drive shaft, a plunger, a plunger retainer, a rolling head assembly and a plunger pre-compressing mechanism arranged inside the plunger retainer. The plunger passes through the center of the drive shaft, and is directly pressed in the center of a microphone head inside a working cavity of the rolling head assembly, thereby preventing the microphone head from rotating with the rolling head during rolling process, preventing internal parts of the microphone head from jumping out during rolling process, and ensuring compactness of the internal parts of the microphone head. Pre-compressing force on the plunger retainer is realized through the compression of a spring, and a pressure adjusting bolt on the spring can be rotated to conveniently adjust the pre-compressing force according to requirements of different products. The rolling device of the electret microphone has the advantages of stable structure, consistent spring pressure during rolling process and good consistency of products, pressure of the whole device keeps consistent during rolling process, and rolling quality is increased. Rolling plunger retaining blocks are mounted on a rolling head seat through an adjustable locating mechanism, and the adjustable locating mechanism is used for adjusting the diameter of the rolling plunger according to size of the microphone head. The rolling device of the electret microphone has a wide application range.
