Abstract: A vibration motor and an electronic device are provided. The vibration motor may be applied to electronic devices such as a mobile phone and a PAD. A partial region of a first side wall of a housing of the vibration motor protrudes outward to form a concave cavity with an opening facing a movable component. A driving coil is partially or completely located in the concave cavity. In a case that a same electromagnetic force is achieved, the vibration motor in this application may reduce a height of the driving coil protruding from the opening of the concave cavity as much as possible.

Abstract: A method and an apparatus for adjusting a vibration waveform of a linear motor. At least one of the following steps is performed: obtaining a frequency of a steady-state waveform of a vibration description file, and mapping the frequency to a target frequency according to a preset first mapping rule and a frequency of the linear motor; or obtaining a transient waveform of the vibration description file and expanding the transient waveform into a waveform sequence formed by a plurality of target transient waveforms, where the frequency of the waveform sequence is the same as a frequency of the transient waveform of the vibration description file, and a frequency of a target transient waveform is adapted to the linear motor. Therefore, both the steady-state waveform and the transient waveform can be adapted to the characteristics of the linear motor, thereby improving the vibration effect of the linear motor.

Abstract: Embodiments of this application provide a method and system for measuring motor damping. In the method for measuring motor damping, a driving signal is generated to drive a to-be-tested motor to operate, and at a cut-off moment of the driving signal, the to-be-tested motor enters a free damping state and a turn-off signal is generated at this moment to cut off a test circuit of the to-be-tested motor. In this way, an acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state can be acquired, and damping of the to-be-tested motor is obtained by using the acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state, thereby realizing the measurement of the damping of the to-be-tested motor.
