Dear users,
This is all about the weight and the design (eccentricity) of the vibra motor head. The stronger vibration the louder working noise. That depends on your taste which benefit is preferred by you, a noiseless but weaker or a stronger but noisier solution. The only way to change the preferences of the vibration is to replace the vibra motor by a different one.
Regards,
Bence |
