Abstract: A linear motor driving method and circuit and a related apparatus are provided. The method is applied to a linear motor driving circuit. According to the method, the power supply module can supply power to the driver module and the control module, so that the control module can control the driver module to start and drive the linear motor to operate, so as to allow an electronic device to produce a vibration effect; and then the control module can control the driver module to turn off and stop driving the linear motor. However, the linear motor will continue to make damped vibration due to inertia. Specifically, a coil of the linear motor generates an induced electromotive force during vibration. Therefore, after the driver module is turned off, the control module will also control the energy recovery module to recover electric energy generated by the damped vibration of the linear motor.

Abstract: A method for providing application service is provided. The method discloses that a user is authenticated according to a received application service acquisition request from a user mobile phone, and when the user authentication is passed, the application service acquisition request is sent to an application server, so that the application server provides an application service to the user mobile phone according to the application service acquisition request. The application server does not need to authenticate the user mobile phone by performing an authentication operation on the user mobile phone through a wireless application protocol gateway, thus being capable of reducing the workload of the application server.
