Feature: 1. Flat vibration motors are usually in the shape of flat buttons, small in size and light in weight (cylindrical). 2. The vibration strength is caused by the loss of balance of the rotor. The vibrator embedded in the rotor is mainly to increase the unbalance. 3. This vibration motor has radial rotation or circumferential rotation, low noise, low power consumption, strong vibration sense, simple structure, strong reliability, and short response time. 4. This vibration motor has a small size and long service life (72h without stopping is the basic service life). 5. This product is suitable for the current emerging industries of watches, mobile phones, bracelets, mobile phones and tablets.
