According to the power supplying method, power is supplied to a noise canceling circuit of the ANC earphone and its related circuits by the power source of the electronic equipment through a microphone contact, a left channel audio contact, or a right channel audio contact of an earphone jack of the electrical equipment. The power supplying device includes the ANC earphone and the electronic equipment. This invention enables the ANC earphone to directly obtain power from the power source of the electronic equipment, so that the ANC earphone is simple in structure, convenient to carry, suitable for mass production, low in production cost, and high in compatibility."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for supplying power for active noise cancelation earphone by utilization of power source of electronic equipment","description":"A method and device for supplying power for an ANC (Active Noise Cancelation) earphone by utilization of a power source of an electronic equipment.
