Cost, thus reduce market price so that it is can yield unusually brilliant results in consumer electronics market is that practitioner endeavours
Solve.In general, design and the production of dynamic ferrum loudspeaker is (to determine loudspeaker with horn profile size
Acoustical behavior) and impedance distinguish, say, that the dynamic ferrum loudspeaker of same size can correspondence
Several different impedance (being determined by voice coil loudspeaker voice coil, wire rod, the number of turns and line footpath) meets different applied field
Close.
As it is shown in figure 1, current dynamic ferrum loudspeaker 100 generally include vibrating diaphragm 110, flutter 111, drive
Bar 120, upper cover 130, iron core 140, magnetics 150, armature 160, lower casing 170, voice coil loudspeaker voice coil 180,
And PCB 190.Vibrating diaphragm 110, flutter 111, drive rod 120, iron core 140, magnetics 150,
Armature 160, voice coil loudspeaker voice coil 180, all it is contained in the inner chamber of upper cover 130 and lower casing 170.Wherein armature 160
Tongue through voice coil loudspeaker voice coil 180 inner chamber, and be inserted between two pieces of magneticss 150.When voice coil loudspeaker voice coil 180
After energising, becoming electromagnet, along with the change of signal, the magnetic field that electromagnet produces can be along with becoming
Change, produce active force, Continuous Drive armature 160 with magnetics 150.Drive rod 120 one end is fixed
In the tongue of described armature 160, the other end is fixed on the middle side edge of described vibrating diaphragm 110, armature 160
Vibrating diaphragm 110 is driven to make its sounding by drive rod 120.Due to the space of armature 160 to be reserved,
So the concentricity requirement of part assembling is the highest.Simultaneously as armature 160 is through voice coil loudspeaker voice coil 180,
Once assembling up, voice coil loudspeaker voice coil 180 is the most interchangeable.This assembling mode efficiency is low, to workman's skill
Can require the highest, the flexibility of production line is poor.
