Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] An embodiment of the present invention provides an electronic display device. Such as figure 1 and figure 2 As shown, the electronic display device includes a casing, a screen 13 and a vibrating device.

[0027] Specifically, the casing includes a cylindrical side wall 12 and a bottom wall 16 fixed at one end of the side wall 12 . The inside of the housing has an accommodating chamber for accommodating various electronic devices. The screen 13 is provided at an end of the side wall 12 opposite to the bottom wall 16 . A vibrating space 18 is formed between the screen 13 and the casing. ...

Abstract

The invention discloses an electronic display device and an electronic device. The electronic display device comprises a casing, a screen and a vibration device, wherein at least a part of the screenis connected to at least a part of the casing through a flexible connecting device, at least one of the screen and the casing is provided with a receiving groove for fixing the flexible connecting device, the flexible connecting device is elastic, the vibration device is fixed on the screen, and the vibration device is configured to vibrate in response to electrical signals of an external circuitand drive the screen to vibrate and sound. The screen is connected with the casing by the flexible device instead of a fixed connection, and the casing does not vibrate when the screen vibrates, thereby effectively reducing the sound leakage caused by the vibration of the casing. The connection strength of the flexible connecting device to the casing and the screen is improved by the flexible connecting device receiving groove.

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 not only drives the screen to vibrate, but also drives the back shell to vibrate, which will...
