Line.
Preferably, described audio frequency input line is by the first-order low-pass wave circuit of resistance R1 and electric capacity C1 composition
Being connected to low frequency cell, the high pass circuit by electric capacity C2 and C3 composition in parallel is connected to high frequency unit.
Compared with correlation technique, double moving-coil unit high-fidelity headphones that the present invention sends out have the advantages that
1, the sound wave that high frequency moving-coil unit vibrating diaphragm front sends arrives auditory meatus by conduit, and dummy pipe is to high frequency sound wave
There are enhancing and orientation, the interference of front-and-back unit sound wave can be avoided.The antiphase sound wave that the vibrating diaphragm back side sends leads to
Cross conduit and reach outside earphone case, on the one hand avoid the interference of front-and-back unit, on the other hand ensure that vibrating diaphragm two
The air pressure balance in face, reduces distortion.
2, the sound wave that medium and low frequency moving-coil unit vibrating diaphragm front sends passes through around front high frequency moving-coil unit and surrounding catheter
Arrive auditory meatus, there is enhancing and orientation equally, make to reduce during the mixing of the sound wave in arrival auditory meatus mutual doing
Disturb.The antiphase sound wave that the vibrating diaphragm back side sends reaches earphone case by the stepless scalable pore at ear casing rear portion
Outward, by auditory meatus and the balance of external pressure, can arbitrarily regulate the acoustic pressure of low-frequency sound, meet different listening
Sound needs.
3, the present invention is reasonable in design, solves the tuning difficult problem that the most double moving-coil unit earphone generally exists, fully
Play the advantage of multiple-unit earphone, made tonequality significantly be improved.
