Abstract

The embodiment of the invention provides a vibration control method and a mobile terminal. The method comprises the following steps: acquiring a source voice signal; according to a preset vibration model, determining a negative gain which needs to be used for compensating the source voice signal; compensating the source voice signal according to the negative gain to obtain a target voice signal; and controlling the vibration of a sound production device according to the target voice signal. According to the embodiment of the invention, after the source voice signal is compensated according tothe negative gain, the target voice signal of which the partial signal is weaker than the source voice signal can be obtained, so that when the vibration of the sound production device is controlled through the target voice signal, the vibration sense of the sound production device is correspondingly weakened, and the discomfort of a user caused by too strong screen vibration is reduced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a vibration control method and a mobile terminal. Background technique [0002] With the development of mobile terminals, full-screen mobile terminals using screen sound technology have been promoted. Screen sound is the application of "piezoelectric driver technology" to mobile terminals, so that the function of the earpiece can be integrated with the screen, and there is no need to set the earpiece on the front of the mobile terminal to produce sound. hole. [0003] In the prior art, the voice signal is usually converted into an electrical signal of a certain frequency and amplitude and input to the vibration unit drive device. The vibration unit can vibrate under the drive of the vibration drive unit, and the screen of the mobile terminal vibrates with the vibration of the vibration unit. This in turn pushes the air to produce sound. [0004] However, the above-mentioned ...
