1. A flexible vibration motor for providing tactile feedback, comprising:
a passive vibration signal transmission layer; and
a vibration driving layer, comprising an electrode array; wherein
the passive vibration signal transmission layer and the vibration driving layer are arranged adjacent to each other in a vertical direction;
the electrode array is configured to generate an electric field when a control signal is applied to the electrode array;
the passive vibration signal transmission layer is configured to generate induced charges induced by the electric field; and the passive vibration signal transmission layer is further configured to generate vibration to provide tactile feedback under an interaction of the electric field and the induced charges; and
wherein the flexible vibration motor for providing tactile feedback further comprising:
an encapsulation isolation part;
wherein a gas space is formed between the encapsulation isolation part and the passive vibration signal transmission layer, and the vibration driving layer is located in the gas space.
