Electromagnetic oscillating type pump and method for manufacturing the same

摘要

An electromagnetic oscillating compressor for oscillating diaphragms (5) connected to an oscillator (4) through electromagnetic oscillation of the oscillator with magnetic body by utilizing magnetic interaction between an electromagnetic portion (2) comprising one or a plurality of iron cores (20) and the magnetic body. A frame portion (19) of resin mold is formed by molding resin on an outer surface of the electromagnetic portion. It is possible to obtain electromagnetic oscillating type pumps of lower manufacturing costs and exhibiting high acoustic insulating effects.
