Title:
MANUFACTURING PROCESS FOR TOUCH SOUND PRODUCTION DISPLAY UNIT
Document Type and Number:
WIPO Patent Application WO/2023/226762
Kind Code:
A1
Abstract:
Disclosed in the present invention is a manufacturing process for a touch sound production display unit, comprising: attaching a lower end face of a second base material layer to an upper end face of a third base material layer; forming a sound production layer between a first base material and the second base material layer, the first base material and part of the structure of the sound production layer forming a vibration layer of the sound production layer, and the second base material layer, the third base material layer, and the remaining part of the structure of the sound production layer forming a non-vibration layer of the sound production layer; and frame-attaching the vibration layer and the non-vibration layer. According to the present invention, an electrostatic ultrasonic transducer is combined with a touch screen, such that a display device can realize screen-oriented sound production, and can be touched at the same time without interfering with each other; and while screen-oriented sound production, private listening, and avoidance of disturbance to surrounding personnel are achieved, the display device is made to have the touch function, such that the application range of the display device is expanded.
