Embodiment:
See shown in Fig. 1 to Fig. 4: it comprises upper cover body 1, lower cover 2, a magnet 3, No. two magnet 4, copper band 5, vibrating diaphragm 7, voice coil loudspeaker voice coil 6, upper cover body 1 fastens and forms cavity with lower cover 2, in upper cover body 1, be provided with magnet 4 No. two, in lower cover 2, be provided with magnet 3 No. one, between upper cover body 1 and lower cover 2, be provided with copper band 5, a magnet 3, between No. two magnet 4, be provided with vibrating diaphragm 7, voice coil loudspeaker voice coil 6, a magnet 3, gap between No. two magnet 4 and vibrating diaphragm 7 is 0.2-0.4 ㎜, the homopolarity that magnet 3 and No. two magnet 4 repel each other for axial magnetic is oppositely arranged, be arranged at respectively the both sides of voice coil loudspeaker voice coil 6 axis directions, on vibrating diaphragm 7, offer deep-slotted chip breaker 71, in upper cover body 1, have through hole 13, through hole 13 is provided with adjustable sound paper 11, in upper cover body 1, be also provided with the pcb board 12 of anchor leg, adjustable sound paper 11 can allow loudspeaker vibrating effect better.
In the time of energising work, magnet 3, No. two magnet 4 are subject to the effect of electric current, when a magnet 3 absorption vibrating diaphragm 7, No. two magnet 4 can produce magnetic force and push away vibrating diaphragm 7, allow and push away effectively vibration of vibrating diaphragm 7 generations, when electric current diminishes or becomes large at that time, vibrating diaphragm 7 can correspondingly diminish or become greatly and vibrate, and the gap between No. two magnet 4 and vibrating diaphragm 7 is that 0.2-0.4 ㎜ can hold vibrating diaphragm 7 amplitudes.The design of gap three between the thickness of vibrating diaphragm 7, magnet 3, No. two magnet 4 thickness, No. two magnet 4 and vibrating diaphragm 7 is just right according to soniferous amplitude, cooperatively interacts.
The thickness of described vibrating diaphragm 7 is: 4-50 μ m, and vibrating diaphragm 7 thickness 4-50 μ m can complete effective vibration, and vibrating diaphragm 7 is too thin or too thick, all can not complete well the vibration of sounding; Deep-slotted chip breaker 71 is annular, can better carry out the vibration of sounding, has better tonequality simultaneously.
A described magnet 3, No. two magnet 4 thickness are: 0.5-3 ㎜, the magnetism intensity of magnet is just between above-mentioned magnet thickness.
