Problems solved by technology

[0004] However, the first coil and the second coil of the linear vibration motor in the related art are simply connected in series, thereby reducing the current flowing through the first coil and the second coil and prolonging the working time.
However, the response time of the linear vibration stand-alone machine with the above structure is long and the power is small, which cannot meet the requirements of fast response and high power of the linear vibration motor
