Tungsten Alloy Mobile Phone Vibrator

Tungsten alloy mobile phone vibrator is an important part of mobile phone vibration device, and compared with other materials, tungsten alloy has significant advantages in density, hardness, wear resistance and other aspects. When the phone vibrates, there is an eccentric motion, which is caused by the eccentric motors in the vibrating parts. Because the center of gravity is shifted, rather than in the motor rotor, the phone begins to vibrate. In this way, mechanical parts with good wear resistance and high gravity are needed.

Tungsten alloy mobile phone vibrator is an eccentric device used on the mobile phone motor

The motor uses the electromagnetic force of the coil to rotate, when the coil is input current direction X, according to the "Fleming left hand rule", the coil will be pushed upward; At the same time, when the current direction is opposite to the X direction, the coil is pushed downward. The two forces interact. Balance and spin the motor. This force received in a magnetic field when an electric current passes through a coil is called the electromagnetic force. The motor spins constantly under the electromagnetic force. The phone vibrator located at the end vibrates during rotation due to the asymmetry of weight. Mobile phone vibrator has always been in a state of high-speed rotation, so there are high requirements for its wear resistance.

Tungsten alloy has a high density, with a maximum density of 18.6g/cm3. High density can exhibit a smaller volume than other materials for the same weight. This kind of product requires a large weight and a small volume, such as mobile phone vibration, bell vibration parts and so on. Tungsten alloy materials can meet the needs of this kind of products. Compared with other materials, tungsten alloy oscillator has the advantages of accurate weight, non-magnetic, high temperature resistance, oxidation resistance, corrosion resistance and so on.
