Vibration device, touch display panel and electronic product

A vibration device, comprising:

• a base substrate;
• a first transparent conductive anti-diffusion layer, located on the base substrate;
• a piezoelectric material layer, located at a side of the first transparent conductive anti-diffusion layer away from the base substrate, and
• a second transparent electrode, located at a side of the piezoelectric material layer away from the base substrate,
• wherein the first transparent conductive anti-diffusion layer is configured to prevent oxygen from entering the piezoelectric material layer,
• the vibration device further comprising:
• a first transparent electrode, located at a side of the base substrate close to the first transparent conductive anti-diffusion layer, and located between the base substrate and the first transparent conductive anti-diffusion layer,
• wherein a material of the first transparent conductive anti-diffusion layer is a doped material of the first transparent electrode,
• the first transparent electrode is in direct contact with the first transparent conductive anti- diffusion layer, an orthographic projection of an area where the first transparent electrode is in direct contact with the first transparent conductive anti-diffusion layer on the base substrate overlaps with an orthographic projection of the second transparent electrode on the base substrate, the first transparent conductive anti-diffusion layer is further configured to prevent the piezoelectric material layer from losing oxygen.
