The N poles of magnet steel 60, middle magnet steel 70 and outer steel 80 are arranged at one end towards the double folding ring vibrating diaphragm.In addition, middle magnet steel 70 is set
Put in outer steel 80, interior magnet steel 60 is arranged in middle magnet steel 70.
Outer voice coil loudspeaker voice coil 50 is arranged in the space between middle magnet steel 70 and outer steel 80.When outer voice coil loudspeaker voice coil 50 inputs a sinusoidal electricity
When flowing signal, outer voice coil loudspeaker voice coil 50 is in the magnetic field of middle magnet steel 70 and the formation of outer steel 80.It is fixed according to Ampere's law, i.e. right-handed helix
Then, outer voice coil loudspeaker voice coil 50 in axial direction up-down vibration in the presence of by magnetic field force, i.e., outer voice coil loudspeaker voice coil 50 is in middle magnet steel 70 and outer magnetic
Up-down vibration in the presence of steel 80.Because the back side of outer top dome 303 is connected with outer voice coil loudspeaker voice coil 50, the ectosphere in the presence of outer voice coil loudspeaker voice coil 50
Top 303 also in axial direction up-down vibration, i.e., outer top dome 303 up-down vibration in the presence of outer voice coil loudspeaker voice coil 50.Outer top dome 303 is shaken
Dynamic amplitude is influenceed by the strong and weak and outer ring 304 of the current signal in outer voice coil loudspeaker voice coil 50.
Interior voice coil loudspeaker voice coil 40 is arranged in the space between interior magnet steel 60 and middle magnet steel 70.When interior voice coil loudspeaker voice coil 40 inputs a sinusoidal electricity
When flowing signal, and interior voice coil loudspeaker voice coil 40 is synchronous with the sinusoidal current signal in outer voice coil loudspeaker voice coil 50, and interior voice coil loudspeaker voice coil 40 is in interior magnet steel 60 and middle magnet steel
In 70 magnetic fields formed.According to Ampere's law, i.e. right-hand screw rule, interior voice coil loudspeaker voice coil 40 in the presence of by magnetic field force vertically
Direction up-down vibration, i.e., the interior up-down vibration in the presence of interior magnet steel 60 and middle magnet steel 70 of voice coil loudspeaker voice coil 40.Due to the back of the body of interior top dome 301
Face is connected with interior voice coil loudspeaker voice coil 40, in the presence of interior voice coil loudspeaker voice coil 40 in top dome 301 also in axial direction up-down vibration, i.e., interior top dome 301
The up-down vibration in the presence of interior voice coil loudspeaker voice coil 40.Power of the Oscillation Amplitude of interior top dome 301 by the current signal in interior voice coil loudspeaker voice coil 40
And the influence of interior ring 302.
In addition, because outer top dome 303 is connected with interior ring 302, in the Oscillation Amplitude of outer top dome 303 can be directly affected
The Oscillation Amplitude of ring 302；Because interior ring 302 is connected with interior top dome 301, the Oscillation Amplitude of interior ring 302 is again direct
The Oscillation Amplitude of the outer top dome 303 of influence.Therefore, the global vibration amplitude of interior top dome 301 is effect of the interior top dome 301 in interior voice coil loudspeaker voice coil 40
Under Oscillation Amplitude and Oscillation Amplitude of the outer top dome 303 in the presence of outer voice coil loudspeaker voice coil 50 summation.
For example, in the presence of outer voice coil loudspeaker voice coil 50, the Oscillation Amplitude of outer top dome 303 is 0.25 millimeter；In the work of interior voice coil loudspeaker voice coil 40
Under, the Oscillation Amplitude of interior top dome 301 is 0.15 millimeter；In the presence of the interior voice coil loudspeaker voice coil 40 and outer voice coil loudspeaker voice coil 50, in top dome 301
Global vibration amplitude is 0.4 millimeter.
By setting two rings on vibrating diaphragm, the Oscillation Amplitude of interior top dome can be increased.Because volume is the straight of acoustic pressure
Junctor shows, and the size of acoustic pressure is directly related with the volume of air that interior top dome is promoted.Volume of air that interior top dome can be promoted etc.
In the surface area and the product of the maximum vibration amplitude of interior top dome of interior top dome.In the case where interior top dome surface area is constant, interior ball
The Oscillation Amplitude on top is bigger, and the volume of air that interior top dome can be promoted is bigger, and acoustic pressure becomes big therewith, so as to improve the sound of loudspeaker
Amount.
Further, the loudspeaker introduced based on the present embodiment, a kind of method for assembling the loudspeaker presented below：
Step A1：By one-shaping technique, the double folding ring vibrating diaphragm is produced.
Step A2：The top of voice coil loudspeaker voice coil 40 in the back side laminating of the interior top dome 301 of the double folding ring vibrating diaphragm, described two-fold
The top of the outer voice coil loudspeaker voice coil 50 of back side laminating of the outer top dome 303 of ring vibrating diaphragm.
Step A3：Interior magnet steel 60, middle magnet steel and outer steel are fitted successively according to order from the inside to the outside is fixed on pedestal 100
On.
Step A4：The pedestal 100 posted is embedded on support frame 90.
Step A5：The bottom of interior voice coil loudspeaker voice coil 40 and the bottom of outer voice coil loudspeaker voice coil 50 are placed in support frame 90 by spot welding mode respectively
On.
Step A6：The outward flange of the double folding ring vibrating diaphragm posted is fixed on support frame 90 by dispensing mode.
Step A7：Protecgulum 110 is fixed on support frame 90 by way of dispensing and hot melt.
The 3rd embodiment of the application proposes a kind of mobile terminal, and the mobile terminal includes introducing in second embodiment
Loudspeaker.
By setting the loudspeaker in the mobile terminal, the volume of loudspeaker can be lifted, and optimizes loudspeaker
Tonequality.Because the volume of the loudspeaker is as the volume of the loudspeaker used in mobile terminal in the prior art, so
