Embodiment approach

[0031] In the embodiment of the present application, the vibrating component is the screen 120, and the exciter 131 is connected to the screen 120 to drive the screen 120 to vibrate. Specifically, the actuator 131 is attached below the screen 120, and the actuator 131 may be a piezoelectric driver or a motor. As an implementation manner, the actuator 131 is a piezoelectric driver. The piezoelectric driver transmits its own deformation to the screen 120 through the torque action, so that the screen 120 vibrates and makes sound. The screen 120 includes a touch screen 109 and a display panel 111, the display panel 111 is located below the touch screen 109, and the piezoelectric driver is attached below the display panel 111, that is, the side of the display panel 111 away from the touch screen 109. The piezo actuator consists of multilayer piezoceramic sheets. When a multi-layer piezoelectric ceramic sheet expands and contracts with sound, it will drive the screen to bend and d...

Abstract

The embodiment of the invention provides a sound production control method and device, an electronic device and a computer readable medium, and belongs to the technical field of electronic devices. The method comprises the steps that when detecting that the electronic device is in a screen sound production mode, detecting whether a screen sound production area is in an abnormal state or not; if the screen is in the abnormal state, adjusting vibration parameters of the screen sound production area; and controlling an exciter corresponding to the screen sounding area according to the adjusted vibration parameters. Not only can sound be produced through a vibration mode of the screen or the shell, but also a sound outlet hole can be prevented from being formed in the electronic device, and the vibration parameters of the area can be adjusted in time when the area, used for vibration sound production, of the screen is abnormal, so that the vibration area of the screen is protected.

Description

technical field [0001] The present application relates to the technical field of electronic devices, and more specifically, to a method, device, electronic device and computer-readable medium for controlling sound generation. Background technique [0002] Currently, electronic devices, such as mobile phones, tablet computers, etc., output sound signals through loudspeakers. However, the arrangement of the speaker occupies a relatively large design space, which causes the electronic device not to comply with the direction of thin design. Contents of the invention [0003] The present application proposes a sound emission control method, device, electronic device and computer readable medium to improve the above defects. [0004] In the first aspect, the embodiment of the present application provides a sound control method, which is applied to an electronic device, and the electronic device includes a screen and a plurality of exciters for driving the screen to produce soun...
