The present disclosure provides a touch panel assembly and an electronic device. The touch panel assembly includes a touch panel, a touch switch, and a transmission assembly. The touch panel receives a touch operation from a user. The touch switch is positioned below the touch panel and located at a center position of the touch panel. The transmission assembly drives the touch panel to ascend and descend along a vertical direction synchronously and across an entire touch surface, and the touch panel activates the touch switch while descending. When subject to a given force, any touch areas of the touch panel can be pressed down, the touch panel stably moves synchronously and across its entire touch surface, so as to increase product stability. The touch panel assembly can achieve technical effects of a uniform touch feedback and the touch panel's stable movement, and so as to effectively improve user experiences.
