Abstract

The invention discloses an electronic display device and an electronic device, the electronic display device includes a housing, a screen and a vibration device. At least a portion of the screen is connected to at least a portion of the housing by a flexible connection device, at least one of that screen and the house is provided with a receiving groove for fixing the flexible connection device, the flexible connecting device has elasticity, and the vibration device comprises a stator subsystem and a vibration subsystem, wherein the stator subsystem is fixedly connected with the screen througha heat insulating device, the vibration subsystem generates vibration in response to an electric signal of an external circuit and drives the stator to vibrate, and the stator drives the screen to vibrate and sound. The screen and the housing are connected by a flexible device, and the heat insulation device reduces the heat diffusion of the vibration device to the screen and effectively protectsthe screen by providing a flexible connection device accommodating groove to enhance the connection strength between the flexible connection device and the shell and the screen.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to an electronic display device and an electronic device using the electronic display device. Background technique [0002] Electronic terminals with full-screen mode are becoming more and more popular. In order to increase the screen-to-body ratio, the front of the electronic terminal needs to be non-porous, that is, to cancel the sound control of the earpiece and the photosensitive hole of the camera. In some sound-generating device design schemes, a piezoelectric device is placed on the middle frame, and the vibration of the piezoelectric device drives the screen and the rear case of the electronic terminal to vibrate, thereby realizing sound radiation. [0003] Then, in this solution, since the screen and the back shell are fixedly connected, the piezoelectric device will not only drive the vibration of the screen, but also drive the vibration of the back shel...
