20150281843 | DIAPHRAGM SURROUND MANUFACTURING METHOD AND DIAPHRAGM APPLICABLE THERETO - A diaphragm surround manufacturing method includes: mixing a molten plastic and a gas in supercritical fluid state in a feed pipe of an injector to form a mixture; filling a die with the mixture thus formed and controlling pressure and temperature of the die to cause the gas to diffuse and nucleate inside the die and develop a plurality of bubbles; and reducing the temperature of the die to cause the plastic to cure and form a microcellular foam structure. Accordingly, the surround manufactured by the manufacturing method has equal foam cell diameters and uniform foam cell distribution so as to enhance the tensile strength of the surround, enable a diaphragm with the surround to perform well at low frequencies, and extend the service life of the diaphragm. | 10-01-2015 |
