Abstract

The invention provides a mobile terminal which comprises a rear cover, a middle frame, a screen and a printed circuit board. The rear cover, the screen and the printed circuit board are fixedly connected with the middle frame. An exciter is arranged on the middle frame or the screen; a control circuit for controlling the vibration intensity of the exciter is arranged on the printed circuit board;tthe mobile terminal further comprises a vibration sensor used for detecting the sound production state of the screen pushed by the exciter, wherein the vibration sensor is electrically connected withthe control circuit, the control circuit is used for comparing a current value output by the vibration sensor with a preset value, and when the current value output by the vibration sensor is greaterthan the preset value, the control circuit reduces a driving current output to the exciter. According to the method, the condition that the mobile terminal also generates large vibration due to largevibration of the exciter can be effectively avoided, so that the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a mobile terminal. Background technique [0002] With the development of mobile terminals, full-screen sound generation technology is applied in mobile terminals. For example, an exciter is set in the mobile terminal to directly or indirectly push the screen to vibrate, thereby pushing the air to emit sound to the outside. In the prior art, generally, a corresponding driving current is output to drive the exciter to vibrate according to the volume set by the user. However, since the sound is generated through vibration, if the vibration amplitude is too large, the mobile terminal will also generate relatively large vibration, thereby affecting user experience. Contents of the invention [0003] An embodiment of the present invention provides a mobile terminal to solve the problem that the exciter vibrates relatively large, which causes the mobile terminal to generate...
