Method and device for supplying power for ANC earphone by utilization of power source of electronic equipment

Abstract

The invention discloses a method and device for supplying power for an ANC earphone by utilization of a power source of electronic equipment. According to the power supplying method, power is supplied for a noise cancellation circuit of the ANC earphone and circuits related to the noise cancellation circuit of the ANC earphone through a microphone pin and a left sound channel pin or a right sound channel pin, wherein the microphone pin, the left sound channel pin and the right sound channel pin are arranged in an earphone socket of the electronic equipment. The power supplying device comprises the ANC earphone and the electronic equipment, wherein the ANC earphone comprises a detection and control module A and a switch module A, the detection and control module A is connected with an earphone plug, and both the noise cancellation circuit and a hand free microphone circuit are connected with the earphone plug through the switch module A. The electronic equipment comprises a detection and control module B and a switch module B, the detection and control module B is connected with the earphone socket, and both an audio module and a power source module are connected with the earphone socket through the switch module B. The method and device for supplying the power for the ANC earphone by utilization of the power source of the electronic equipment can enable the ANC to directly fetching power from the power source of the electronic equipment, and enables the earphone to have the advantages of being simple in structure, convenient to carry and suitable for mass production, reducing production cost, and being high in compatibility.

Description

technical field [0001] The invention relates to a method and equipment for supplying power to an ANC earphone by using a power supply of an electronic equipment, and belongs to the field of audio equipment. Background technique [0002] With the emergence and popularization of various smart electronic devices, earphones have become a very important electronic device accessory in people's daily life. However, a noisy environment will greatly reduce the accuracy of people receiving sound information with earphones, especially for business people who travel frequently and take airplanes, office workers who squeeze subways and buses, and office workers in central air-conditioned rooms. Therefore, the demand for noise-canceling headphones is also growing rapidly. [0003] ANC (Active Noise Cancellation) earphones are a kind of noise-cancelling earphones. Different from ordinary earphones, ANC earphones are equipped with a noise cancellation circuit for eliminating noise in addit...

Problems solved by technology

This method needs to change the structure of the plug and socket of the earphone, that is, the structure of the 5-pole earphone plug and socket. In order to realize the noise reduction function, the 5-pole plug and the 5-pole socket must be used together. Even if the noise reduction function is abandoned, The earphones cannot be used in connection with common electronic equipment (4-pole earphone socket), which reduces the compatibility of earphones and electronic equipment
