Abstract

The invention relates to a noise cancelling bluetooth headset, in particular to a noise cancelling bluetooth headset which is relatively good in noise cancelling effect and convenient to use, and overcomes the defects that the conventional headset is difficult to be switched in wired / wireless transmission ways at any moment, and poor in music quality. The invention provides the noise cancelling bluetooth headset which can realize the automatic wired / wireless switch, and is relatively good in audio playback effect. In the noise cancelling bluetooth headset, a physical noise cancelling structure and an internal noise cancelling circuit are respectively adopted to process noise inside and outside the headset, the physical noise cancelling structure is used for isolating external high frequency noise, and meanwhile, the internal noise cancelling circuit is used for eliminating internal noise during the transmission process of the low and medium frequency noise and audio signals entering the headset, so that the audio signal entering the human ears finally is not affected by noise completely.

Description

【Technical field】 [0001] The invention relates to an earphone, in particular to a bluetooth noise-reduction earphone with better noise reduction effect and more convenient use. 【Background technique】 [0002] With the rapid development of modern communication technology, the use of electronic equipment such as mobile phones is becoming more and more widespread. However, due to the relatively large electromagnetic radiation in mobile phones, it may cause certain hidden dangers to the health of users. Under this technical background, a bluetooth earphone using short-distance wireless transmission technology has appeared, which separates the microphone, electroacoustic conversion module and mobile phone from the space, so that the user can keep in touch with the mobile phone with strong radiation when using the mobile phone. At the same time, the user does not need a handheld device when talking, which is more concise and convenient to use, especially in occasions that require ...
