Abstract:
Disclosed in the present invention are a touch sound production display unit and apparatus. The unit comprises, successively stacked from top to bottom, a first substrate, a sound production layer, a second substrate layer and a third substrate layer, the sound production layer being located between the first substrate and the second substrate layer and forming in cooperation with the first substrate and the second substrate layer a sound production area and a non sound production area which are separately arranged, the second substrate layer and the third substrate layer forming in cooperation a touch area and a non touch area which are separately arranged, and the sound production area and the touch area being arranged in a staggered mode. In the present invention, an electrostatic ultrasonic transducer is combined with a touch screen, so that of a screen of the display apparatus, one side can directionally produce sound while the other side can be touched for control, avoiding interference between the two sides, which allows the screen to have a touch function and expands the application range thereof while achieving the directional sound production of the screen and private listening as well as avoiding interference with surrounding users.
