Description
Technical field
The present invention relates to a kind of vibrator, more particularly to a kind of linear vibrator.
Background technology
In the prior art as the vibrator used for mobile phone and some mobile electronic products, generally drag cup horse
Reach, and flat motor, because drag cup motor is cylinder, it is impossible to be made very thin, flat motor can be made thin, but shake
Fatigue resistance can weaken, and they have a deadly defect, it is necessary to by brush power transmission to rotor, and vibrator can be made to use the longevity
The life time is short or noise is big.
Chinese invention patent (201210067388.8：Vibrator) a kind of vibrator is disclosed, the vibrator includes：Shell
Body, there is inner space；Coil, it is fixedly mounted in the side wall of housing, coil has the shape of cylinder, so that magnet is placed in
In coil, coil is arranged on the edge of lower house；Elastic component, it is fixedly mounted on housing, to be placed in coil；Matter
Body is measured, is fixedly mounted on elastic component；Elastic component is formed as leaf spring, and elastic component includes mass body bound fraction；Magnetic
Body, it is fixedly mounted on mass body, with face of coil.Circuit board, from the inside of housing by the outside of pull to housing and company
It is connected to coil；Damping member, it is arranged on housing, with face of mass body；Protective component is set, protectiveness component is consolidated
Surely it is arranged on the inner surface of coil, to prevent coil to be damaged., should although the vibrator oscillation intensity is stronger first
Mass body is vertical movement, therefore mass body can not be made thin, otherwise can damage mass body, therefore vibrator will be thicker, volume
With regard to larger, secondly, noise is reduced using damping member in the vibrator, although serving certain effect, increase resistance
Buddhist nun's component make it that vibrator structure is complicated, volume change is big, and cost accordingly increases.In addition, do not driven on the vibrator circuit plate
Dynamic IC, thus with mobile phone or other using on product when need to be programmed again, it is impossible to being mounted directly can just use, and lead to
It is not strong with property.
Chinese invention patent (207270065772.2：Vibrator) a kind of vibrator is disclosed, including：Housing, have interior
Portion space；Vibration produces part, and installation in the housing, and produces vibration by being fed to the electric power of vibration generation part；Altogether
Shake part, is resonated by caused vibration in producing part in vibration；Wherein, the housing is in the shape of the figure of eight, is had
Have：First space segment, vibration generation are partially installed in first space segment；Second space part, it is empty to be connected to first
Between part, and resonate be partially installed in the second space part；The vibration generation is partly comprised in the first space segment
It is interior elastic according to the magnet of order setting from top to bottom, circuit board, the first wt pts, the first installation component, coil and first
Component, one end of the circuit board is drawn out to the outside of housing, and the other end of the circuit board is connected to the coil；Magnet,
It is fixedly mounted in the middle body of the first space segment；Although the vibrator makes in vibration generating unit by using resonance part
Caused vibration amplification, can strengthen vibration in the case of amount of power consumption identical in point, but the vibrator elastic member with shake
When dynamic part vibrates, elastic component directly contacts with the inwall and wt pts of housing, can produce high vibration, causes to make an uproar
Sound is big, and the mass body is hollow cylindrical structure, and mass body can not be too thin, otherwise can influence vibrating effect, therefore cause volume
It is larger.
