Active noise reduction earphone based on double Marx circuits

The utility model discloses an active noise reduction earphone based on double Marx circuits. The active noise reduction earphone comprises a first microphone, a second microphone, a pulse signal generation module, a first noise cancellation module, a second noise cancellation module and an earphone built-in loudspeaker. According to the utility model, the double Marx circuits are adopted, pulse output with different polarities and different amplitudes is realized, and high-decibel low-frequency noise and high-frequency low-decibel noise are offset, so that the noise reduction requirement of the earphone in a high-decibel periodic low-frequency noise prominent environment is met. 本实用新型公开一种基于双Marx电路的主动降噪耳机，包括第一麦克风、第二麦克风、脉冲信号生成模块、第一噪声抵消模块、第二噪声抵消模块和耳机内置扬声器；本实用新型采用双Marx电路，实现不同极性、不同幅值的脉冲输出，实现高分贝低频噪声和高频低分贝噪声的抵消，以满足高分贝周期性低频噪声突出环境下的耳机降噪需求。
