Abstract

The invention discloses a vibrating motor which comprises a motor body, wherein the motor body is provided with two lead wires, namely, a positive lead wire and a negative lead wire; the positive lead wire and the negative lead wire are connected with a drive circuit and a coil of the motor body; when inputting level signals to the positive lead wire and the negative lead wire, the drive circuit periodically and sequentially inputs a positive level signal and a negative level signal to the positive lead wire, during a signal input period, the input time of the positive level signal is the same as the input time of the negative level signal, and the absolute value of the positive level signal is the same as the absolute value of the negative level signal; the drive circuit continuously inputs negative level signals to the negative lead wire. According to the vibrating motor and a mobile terminal provided by the invention, a smartphone placed on the table surface is prevented from continuously moving in one direction due to the vibration of the vibrating motor and further falling on the ground from the table surface, so that the risk that the smartphone is broken is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a vibration motor and a mobile terminal. Background technique [0002] Vibration motors are an essential part of smartphones. The reminder functions of smartphones, such as incoming call reminders, alarm clock reminders, and message push reminders, all use the vibration function of the vibration motor. The vibration motor works based on the principle of electromagnetic induction. The coil of the vibration motor is placed in the magnetic field of the smart phone, and the current is passed through the coil. The coil will be affected by the Loren magnetic force, and then the vibration motor will be driven to rotate. Because the rotor of the vibration motor It is not centrally symmetrical, and the vibration motor will have a strong sense of vibration when it rotates. [0003] In the existing smart phone, the rotor of the vibration motor in it will always only rotate in one di...
