Abstract
A mobile terminal, including: middle frame, main screen and secondary screen arranged at the middle frame. The secondary screen is arranged, in folded state, at back side of the main screen or at side of the main screen. The mobile terminal further includes at least one piezoelectric actuator fixed in the middle frame. The middle frame includes bottom wall and side wall bent and extending from the bottom wall to form receiving space. The piezoelectric actuator has one side fixed to the bottom wall, and another side fixed to the secondary screen. The piezoelectric actuator converts transverse deformation of the piezoelectric actuator into longitudinal driving force to drive the secondary screen to vibrate and sound and provide tactile feedback for the secondary screen. The piezoelectric actuator can improve overall firmness of the mobile terminal, and facilitating waterproof and dustproof effects, thereby enriching use experience.
