Type C interface earphone and implementation method thereof

Abstract

The invention provides a Type-C interface earphone and an implementation method thereof. The earphone comprises a Type C interface, a microcontroller unit, a feedforward noise reduction microphone, afirst noise reduction circuit and a second noise reduction circuit, wherein the Type C interface is used for receiving the voice signals transmitted by the terminal equipment; the microcontroller unitis connected with the Type C interface and is used for controlling the Type C interface to receive the voice signals; the feedforward noise reduction microphone is used for detecting an ambient noisesignal; the first noise reduction circuit is used for receiving the ambient noise signal output by the feedforward noise reduction microphone, and transmitting the noise-reduced ambient noise signalto the microcontroller unit; and the second noise reduction circuit is used for receiving the analog voice signal generated by the microcontroller unit, and outputting the analog voice output signal after second noise reduction processing to the loudspeaker, wherein the microcontroller unit is further used for carrying out analog-to-digital conversion and digital-to-analogue conversion processingon the voice signal and the noise-reduced ambient noise signal so as to generate an analog voice signal and outputting the analog voice signal to the second noise reduction circuit. According to the earphone and the implementation method, the requirements of a user to call and listen to a song in a noisy environment are met, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of audio communication, in particular to a Type C interface earphone and an implementation method thereof. Background technique [0002] With the rapid development of various electronic products, earphones have become very important and common electronic product accessories in people's daily life. At the same time, consumers have higher and higher requirements for diversified functions of earphones. Especially the Type-C interface connection, which has the advantages of thin interface, no directionality, fast charging, stable data transmission, fast transmission speed, and anti-interference. Huawei, the consumer leader in the domestic electronics industry, has started to develop and invest in Type-C earphones. Vivo has been developing Type-C earphones and has begun to equip them with its smartphones. The new generation of mobile phones of Apple, a major foreign electronic consumer brand The standard 3.5mm h...

Problems solved by technology

[0003] On the other hand, the degree of urbanization and urbanization in the world is getting higher and higher, and the noise pollution in cities is becoming more and more serious. In a noisy environment, the accuracy and comfort of people using headphones to receive sound signals will be greatly reduced.

Ordinary earphones can only mask the noise by increasing the volume, which will not allow you to enjoy wonderful music, and will also cause great damage to your hearing
