Tungsten alloy mobile vibrator is an important component of mobile phone vibration device. Compared with other materials, tungsten alloy has remarkable advantages in density, hardness and wear resistance.

When mobile phone vibrates, there is an eccentric motion, which is caused by eccentric motor with vibrating components. As the center of the gravity is eccentric, and is not in the rotor of motor, then the mobile phone vibrates. In this case, component with good properties of wear resistant and high specific gravity is required.

 

 

The purpose of tungsten alloy mobile vibrator is to allow the eccentric device in the mobile to be brought into a weight imbalance state, resulting in a slight vibration when the motor rotates at high speed. Mobile vibrators are made of tungsten heavy alloy with high density, which is very effective in creating an eccentric environment.

 

The motor is rotated by the electromagnetic force of the coil. When the coil is input, and the current is X, the coil will be pushed upward; at the same time, when the current direction is reversed in the direction of X, the coil is pushed downward. The two forces interact with each other. When it reaches balance, the motor.rotates. The motor keeps spinning with the force of the electromagnetic. The mobile vibrator at the end causes vibration during rotation for the asymmetry of weight. Mobile phone vibrator is always in high speed rotating state, so it has higher requirements for its wear resistance.

 

Tungsten alloy is of great density and the maximum density is 18.6g/cm3. High density can be shown from that at the same weight but the volume is smaller than that of other materials. And this product requires a lot of weight and a small volume, such as mobile vibration, bell vibration components, etc. Tungsten alloy material can meet the demand of this kind of products. Compared with other materials, tungsten alloy vibrator has the advantages of accurate weight, non-magnetic, high temperature resistance, oxidation and corrosion resistance.
