Abstract
The invention relates to moving-iron earphones and particularly relates to double-layer-voice-coil-group moving-iron earphones. The double-layer-voice-coil-group moving-iron earphones comprise a magnetic voice diaphragm, voice coils, magnetic conductors and a shell, and are characterized in that the number of voice coil groups formed by the voice coils and the magnetic conductors is greater than 6, and all voice coil groups are uniformly distributed above and below the magnetic voice diaphragm in two layers. The voice coil groups are driven by voice frequency current so as to generate relatively-uniform magnetic fields at the upper and lower ends of the magnetic diaphragm, so that the overall stress of the surface of the magnetic voice diaphragm is uniform, and generated sound waves have the characteristics of little distortion, high dynamicity and sensitive response.
Description
Technical field
The present invention relates to a kind of earphone, the audible device of the moving iron earphone of especially a kind of double-deck voice coil loudspeaker voice coil group.
Background technology
Present ear speaker device normally adopts one group of concentrically ringed voice coil loudspeaker voice coil of sound film lower magnet and energising to interact, and voice coil loudspeaker voice coil drives the vibrations of sound film and produces sound wave, because voice coil loudspeaker voice coil is little with the sound film contact area, and the distortion easily produced.I was at application earphone magnetic diaphragm in 2012, and patent of invention publication No. CN 103297899 A, only carry out technological innovation to the earphone magnetic diaphragm, but do not carry uniform magnetic field is designed under magnetic diaphragm.
Summary of the invention
Purpose of the present invention is addressing the aforementioned drawbacks, and provides a kind of double-deck voice coil loudspeaker voice coil group to move the iron earphone.
In order to achieve the above object, the present invention takes following technical scheme: the voice coil loudspeaker voice coil group be comprised of voice coil loudspeaker voice coil and magnetic conductor is more than 6 groups, and each voice coil loudspeaker voice coil component is two-layer to be uniformly distributed at the magnetic diaphragm upper and lower.
The voice coil loudspeaker voice coil group be comprised of voice coil loudspeaker voice coil and magnetic conductor is more than 6 groups, and each voice coil loudspeaker voice coil component is two-layer to be uniformly distributed at the magnetic diaphragm upper and lower.
The voice coil loudspeaker voice coil group that In-Ear moving iron earphone is comprised of voice coil loudspeaker voice coil and magnetic conductor particularly is 6 groups to 40 groups.
The voice coil loudspeaker voice coil group that non-pleasant moving iron earphone is comprised of voice coil loudspeaker voice coil and magnetic conductor particularly is 6 groups to 400 groups.
The voice coil loudspeaker voice coil group that non-pleasant moving iron earphone is comprised of voice coil loudspeaker voice coil and magnetic conductor particularly is 8 groups to 100 groups.
More specifically each voice coil loudspeaker voice coil group quantity of upper and lower is identical.
Magnetic conductor is that multi-disc magnetic conductor bar forms particularly.
More specifically magnetic conductor is that silicon steel sheet forms.
Magnetic conductor is cylinder or prism particularly.
Each voice coil loudspeaker voice coil group is uniformly distributed in magnetic diaphragm upper and lower left-right symmetric particularly.
More specifically each voice coil loudspeaker voice coil group is identical or close with the magnetic diaphragm distance.
Beneficial effect of the present invention is: at tone currents, drive many group voice coil loudspeaker voice coils in the upper and lower two-layer distribution of magnetic diaphragm, produce relative uniform magnetic field, make the magnetic diaphragm surface integral stressed evenly, institute's sound wave distortion that produces is little, greatly dynamic, is quick on the draw.
The accompanying drawing explanation
