Description
Technical field
The invention belongs to denoising device technical field, and in particular to a kind of dress of the active noise cancelling headphone tonequality lifting of energy
Put.
Background technology
It is well known that the frequency band of active noise reduction is to be embodied in low-frequency range, this frequency of 50-600HZ is generally referred to
Section, and to accomplish excellent noise reduction effect in this frequency band, it is necessary to low-frequency range sensitivity corresponding to loudspeaker and whole earphone is carried
Height, while more than 1KHZ medium-high frequency sensitivity is also suppressed, otherwise noise reduction is difficult to most preferably.And loudspeaker and whole ear
Low-frequency range sensitivity enhancement corresponding to machine, the result after medium-high frequency is depressed is that the music acoustical quality listened to just is affected,
Sound that low frequency is very heavy very vexed, listen time slightly long point, people can feel very tired out.In addition, the work of this same loudspeaker output
Make mode, also have detrimental effect to the call voice of people, i.e., when opening noise reduction, the environment noise on periphery reduces,
But also the voice of the people aside to be conversed with you is also reduced simultaneously, so caused result is so that double-talk is inadequate
It is smooth.And even some earphone brand companies want to go to make up by electronic circuit, that is also limited, and what is still more paid is
The increase of material cost, time cost increase, low, the undesirable element such as power consumption of the also whole circuit production of production efficiency
It is raw, it is a kind of method to lose more than gain.A kind of device of the active noise cancelling headphone tonequality lifting of energy is proposed for this.
The content of the invention
It is an object of the invention to provide a kind of device of the active noise cancelling headphone tonequality lifting of energy, to solve above-mentioned background

Microphone mic R1 and the input connection of reaction type microphone mic R2 electric signals.
Preferably, the audio signal input device is arranged to mobile phone either MP3.
Preferably, the master control box includes master control circuit board and the battery that conducts electricity, and the master control circuit board is with conducting electricity
Battery is electrically connected with.
The technique effect and advantage of the present invention：The device of the active noise cancelling headphone tonequality lifting of the energy can separately adjustable noise reduction
Audio；The voice and the tonequality of connection music that separately adjustable receiver is received；By being filled in left side sound channel device and the right sound channel
Put the L channel noise reduction horn sp L1 set respectively and L channel voice and music loudspeaker sp L2 and R channel noise reduction horn
Sp R1 and R channel voice and music loudspeaker sp R2, individually it is divided to noise reduction output and voice, music output to two loudspeaker independences
Output, so work together the reduction of drive of influencing each other, and effectively improves voice, the acoustical quality of music.
