When air enters the front of the converging-diverging nozzle, its velocity accelerates as it flows through the smaller cross-sectional area in the middle section, which causes a drop in pressure in the middle section and a resulting vacuum in the connecting tubing. This vacuum draws sweat from the bottom of the inner ear toward the middle of the converging-diverging nozzle, where it drips out of either end, resulting in sweat being removed from the inner ear."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sweat proof earphones","description":"The present invention provides a device for removing sweat from the inner ear by creating a vacuum in connecting tubing between the inner ear and a converging-diverging nozzle.
