Tungsten alloy blocks are used in mobile phone vibrators

Your phone vibrates thanks to its vibrator, but an important part of the vibrator is the vibrator, which is made of tungsten alloy blocks.  When the phone vibrates, there is eccentric movement, which is caused by the eccentric motor in the vibrating part.  

The motor uses the electromagnetic force of the coil to rotate. When the coil is input current in the direction of X, according to "Fleming's left hand law", the coil will be pushed up;  At the same time, when the current direction is opposite the X direction, the coil is pushed down.  The two forces interact with each other.  Balance and spin the motor.  The force received in the magnetic field by the current passing through the coil is called the electromagnetic force.  The horse spins constantly under the pull of the electromagnetic force.  The vibrator at the end of the phone vibrates during rotation due to the asymmetry of its weight.  The vibrator of mobile phone is always in the state of high-speed rotation, so its wear resistance has higher requirements.  

The density of tungsten alloy block is very large, that is, the mass of tungsten alloy block is much larger than other materials in the same volume, so it is particularly suitable for the application of miniaturized and thin smart phones or clocks in the vibration parts.  In addition, the tungsten alloy vibrator also has the advantages of non-magnetic, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance and so on, which can meet the high performance requirements of the mobile phone vibrator in the state of high-speed rotation.
