The driver has a transducer diaphragm. The nozzle has an internal passage having an inlet opening, an outlet opening, and a wall connecting the inlet opening and the outlet opening. The wall has an inner surface within the passage. The inner surface extends from the inlet opening to the outlet opening. The outlet opening is smaller area than the inlet opening. The inner surface is configured, based on at least one tractrix, between the inlet opening and the outlet opening. The nozzle is attached to the driver with the transducer diaphragm facing the inlet opening and the inlet opening positioned nearer to the diaphragm than is the outlet opening."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Earphone nozzle comprising tractrix-curved acoustic passage","description":"An earphone includes a driver and a nozzle.
