Description
Technical field
The utility model relates to a kind of intelligent wideband noise cancelling headphone.
Background technology
Along with the development environment of civilization is polluted the chronic illness that has also become contemporary society.And comprise air pollution, pollution of waterhead and noise pollution among environmental pollution.And for the music-lover, what does not have more more irritating than noise.
Now in life, the earphone scope of application is very wide, along with the fast development of science and technology, the earphone technology more and more moves to maturity, and city noise pollutes also more and more serious simultaneously, when outdoor application common headphones earplug, can only cover noise by improving volume, but so not only can not enjoy music, oneself hearing is worked the mischief, but existing earphone volume is large, and the long periods of wear ear causes uncomfortable; When listening to the music, due to the noise reduction technology imperfection, cause lower tone under noisy environment is arranged, can not enjoy the enjoyment that music is brought; Therefore solve comfortable wear, good pronunciation and the earphone noise reduction technology has been proposed Secretary.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of tonequality is good, noise reduction and the good intelligent wideband noise cancelling headphone of soundproof effect.
For solving above technical problem, the utility model is realized by the following technical solutions: a kind of intelligent wideband noise cancelling headphone, comprise pcb board, and be arranged on microprocessor and noise spectrum analysis module on pcb board, and be connected to the sound collector of pcb board input and the loud speaker of output, and be connected to tonequality adjuster on loud speaker, described noise spectrum analysis module is connected on microprocessor, described microprocessor input is connected with sound transducer, is connected with analog to digital converter between described sound transducer and microprocessor.
Further, described pcb board is provided with power circuit, voltage stabilizing circuit and sound insulation circuit, described voltage stabilizing circuit is connected on power circuit, and described sound insulation circuit one end is connected to power circuit by voltage stabilizing circuit, and the described sound insulation circuit other end is connected on the noise spectrum analysis module.
Further, described pcb board also is provided with sound insulation module.
The advantage of the utility model intelligence wideband noise cancelling headphone is:
1) people are the quality that can improve music listening to the music;
2) do not need super large sound just can hear sound;
3) have under noisy environment can noise reduction and the effect of sound insulation; Ensure the tonequality of music;
4) can not cause because of wearing earphone for a long time the uncomfortable of ear, reduce the stimulation to ear and ear-drum.
