Abstract: A touch feedback device and an electronic device are provided. The touch feedback device includes a touch panel; a linear vibration motor arranged on the touch panel and being able to drive the touch panel to vibrate; a mounting member; and a mounting base. The mounting member includes at least one fixing part and a body that is elastic. The touch panel is fixed to the body, and the at least one fixing part is configured to fix the body to the mounting base, in such a manner the touch panel is limited to vibrate along any direction in a horizontal direction. The natural frequency of the touch feedback device can be effectively regulated, and the linear vibration motor at any position on the touch panel does not have much effect on the vibration distribution of the touch panel, thereby improving the vibration touch of the touch feedback device.
