Abstract

The invention provides a noise canceling headphone. The noise canceling headphone comprises a noise acquisition module respectively connected to an induction module and a judgment module; and a noise reduction circuit module respectively connected to the judgment module and a headphone module; when the induction module detects that a headphone is in use, then a noise signal in an environment of the noise acquisition module is started, the noise signal is transmitted to the judgment module to be analyzed and judged, and an analysis and judgment result is transmitted to the noise reduction circuit module; if the judgment result is a judgment result of opening a noise reduction function, then the noise reduction function is opened, and a de-noised audio is played through the headphone module; and if the judgment result is a judgment result of closing the noise reduction function, then the noise reduction function is closed. The invention further provides a noise reduction method applicable to the noise canceling headphone. By using the noise canceling headphone and the noise reduction method provided by the invention, automatic noise reduction can be realized, and the noise reduction function can be opened or closed automatically and timely according to the use state of the headphone on the premise that a key or a toggle switch on the headphone is not required.

Description

technical field [0001] The invention relates to an electroacoustic conversion technology, in particular to a noise reduction earphone and a noise reduction method. Background technique [0002] In the prior art, the noise-cancelling earphones all use an independent circuit control unit, and generally need to be installed with a battery, so the issue of battery life is very important. To solve this problem, the existing solution is to design a noise-cancelling switch on the noise-cancelling earphones , through the switch to turn on or off the noise reduction function, but this method needs to be manually controlled, if the user forgets to turn off this function, the earphone will always be in the noise reduction processing state, which will soon drain the battery, resulting in a short battery life. Replace batteries frequently. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide...
