Embodiments of the present invention provide a screen sound emitting device, method and mobile terminal, the device comprising: at least one temperature detection module, a vibration module, a vibration driving module, a control module, and a screen. In the embodiment of the present invention, the vibration module is attached to the screen, and at least one temperature detection module is installed at a position not exceeding a preset distance from the vibration module. When the vibration module is working, the control module obtains the temperature detected by the at least one temperature detection module. temperature value, and determine the input power of the vibration drive module according to the temperature value, and then the vibration drive module can drive the vibration of the vibration module according to the input power, so that when the vibration module has more heat dissipation during operation, the vibration input power can be automatically adjusted to reduce The heat is dissipated to avoid damage to the screen. The vibration module can be attached to the screen, so that the screen can sensitively perceive the vibration of the vibration module and achieve a good vibration effect when the screen can guarantee normal operation.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a screen sound generating device, method and 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 earpiece function is integrated with the screen, and there is no need to set the earpiece sound hole on the front of the mobile terminal. , when the piezoelectric driver is energized and working, the screen of the mobile terminal vibrates accordingly, and then pushes the air to generate sound. [0003] In the prior art mobile terminal with sound from the screen, the piezoelectric driver is usually installed in the middle frame of the mobile terminal. However, the piezoelectric driver installed in the middle frame brings weak vibration to the screen, ...
