At this moment, it can be formed by yoke and support, by shell and pole plate and be eventually returned to from the magnetic line of force of permanent magnet
The closure ferromagnetic circuit of permanent magnet.
In addition, when producing gravitation by electromagnetic force and magnetic force, touching for yoke and permanent magnet may be caused.Therefore, can be forever
Magnetic fluid is smeared on magnet, magnetic cushion effect is played, both is kept certain distance, so as to reduce making an uproar caused by touching
Sound.
In addition, when producing the rising of repulsion vibrating body by electromagnetic force and magnetic force, it is possible to create because being touched on the upside of shell and pole plate
Caused noise.Therefore, magnetic fluid is applied on the upside of pole plate, then can collects annular magnetic flow along the cylinder of permanent magnet
Body, because the closure that this magnetic fluid is formed between permanent magnet, pole plate, magnetic fluid and the shell that is made up of magnetic material is ferromagnetic
Loop, acted on by magnetic cushion and keep certain distance, so as to reduce due to noise caused by contact.
In addition, the closure ferromagnetic circuit being thusly-formed, if the external power source connected by PCB disappears, with regard to that can make to pass through
Close and balance is formed between the magnetic force of ferromagnetic circuit and the elastic recovering force of elastic component, so as to stop being driven up and down by interaction power supply
Dynamic vibrating body.
Fig. 9 is another applicable case based on the present invention, it is illustrated that the cross-section structure of linear vibrator bonding state, is to delete
Except the pole plate on the upside of permanent magnet is formed.Including producing the coil of electromagnetic force, the yoke being incorporated on the inside of coil, yoke outside and branch
Frame be combined the fixed body of composition, be set to in above-mentioned yoke surface, produce the magnetic field with direction and intensity permanent magnet, by
The vibrating body that the mass body combined with permanent magnet is formed.
The elastic component and fixed body combined with vibrating body and fixed body and vibrating body and elastic component and hollow shell
It is bonded, effectively to transmit the vibration of above-mentioned vibrating body.
