Acoustically transparent membrane module with high resistance to water pressure and manufacture method thereof

Abstract

The invention discloses an acoustically transparent membrane module with high resistance to water pressure and a manufacture method thereof; the acoustically transparent membrane module with high resistance to water pressure comprises acoustically transparent expanded polytetrafluoroethylene coating film with high resistance to water pressure, pressure-sensitive tape and release paper; the acoustically transparent expanded polytetrafluoroethylene coating film with high resistance to water pressure comprises a coating layer with gas molecular micropores and an expanded polytetrafluoroethylene film layer, one side of the expanded polytetrafluoroethylene film layer is coated with the coating layer with gas molecular micropores, the outer side of the pressure-sensitive tape is provided with the release paper, and the pressure-sensitive tape is fitted to both the front and back of the acoustically transparent expanded polytetrafluoroethylene coating film. The manufacture method comprises: manufacturing hydrophobic oleophobic expanded polytetrafluoroethylene film; preparing coating liquid with gas molecular micropores; preparing the acoustically transparent expanded polytetrafluoroethylene coating film with high resistance to water pressure; preparing the acoustically transparent membrane module with high resistance to water pressure. The acoustically transparent membrane module with high resistance to water pressure has very high resistance to water pressure, can ensure conservations from a speaker are clear and distortionless, and has huge application market potential in terms of consumer electronics.

Description

technical field [0001] The invention relates to the field of consumer electronics, in particular to a high water pressure resistant sound-permeable membrane component and a manufacturing method thereof. Background technique [0002] At present, the water pressure resistance of the dust-proof non-woven fabrics and expanded polytetrafluoroethylene films commonly used in consumer electronics housings and micro-speakers on the market is very low, generally lower than 60KPa, which cannot meet the needs of emerging industries. , such as diving travel activities, diving watches, smart watches and diving sports cameras brought by divers generally work at a water depth of 30 meters to 50 meters, requiring clear and undistorted voice calls; and newly developed high-end notebook computers and waterproof mobile phones Most of the sound-transmitting membranes have put forward the requirement of water pressure resistance of 30 meters to 50 meters, so the common sound-transmitting membrane...
