Problems solved by technology
However, the current active noise reduction technology used in headphones only has a constant noise reduction curve. Due to the great difference in sound transmission under different air pressure conditions, it also has a great impact on sound quality. A constant noise reduction curve is difficult to meet the user's noise reduction requirements. Require

Embodiment Construction
[0032] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, a new type of active noise canceling headphones, including:
[0034] Air pressure sensor 1, used to test the atmospheric pressure value of the environment where the earphone is located;
[0035] The audio collection module 2 collects the sound and converts it into the first audio;
[0036] The noise reduction processing module 4 selects corresponding noise reduction parameters to perform noise reduction processing on the first audio frequency and the second audio frequency according to the atmospheric pressure value measured by the air pressure sensor 1;
[0037] The audio input and output module 3 is used to interact with the smart terminal data and input the second audio and output the first audio after noise reduction processing under the condition of interacting with the...

The invention discloses a novel initiative noise reduction headset, which comprises an air pressure sensor used for testing an atmosphere pressure value of an environment where the headset is placed;an audio collection module used for collecting a voice and converting the voice into a first audio; an audio input / output module used for performing data interaction with an intelligent terminal, inputting a second audio and outputting the first audio; a noise reduction processing module used for selecting a corresponding noise reduction parameter to perform noise reduction processing on the firstaudio and the second audio according to the atmosphere pressure value tested by the air pressure sensor; and a loudspeaker used for playing the second audio subjected to the noise reduction processing, wherein the air pressure sensor, the audio collection module, the audio input / output module and the loudspeaker are all connected with the noise reduction processing module. The novel initiative noise reduction headset disclosed by the invention can select the corresponding noise reduction parameter according to the atmosphere pressure value tested by the air pressure sensor to perform the noise reduction processing on an audio signal, so that the noise reduction effect is good; and a noise reduction demand of a user can be met, and a better experience can be brought to the user.
Description
technical field [0001] The invention relates to the technical field of earphones, in particular to a novel active noise reduction earphone. Background technique [0002] Earphones have been widely used in people's daily life and work. In addition to the functions of enjoying music and entertainment, earphones are also widely used to isolate noise and maintain a relatively quiet environment. Noise effects and capabilities are limited. [0003] The method adopted by the active noise reduction technology is to generate a signal with the same amplitude and opposite phase as the external noise to cancel the noise entering the earphone. However, the current active noise reduction technology used in headphones only has a constant noise reduction curve. Due to the great difference in sound transmission under different air pressure conditions, it also has a great impact on sound quality. A constant noise reduction curve is difficult to meet the user's noise reduction requirements. ...
