Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

The first embodiment is as follows:

as shown in fig. 3, 4, 5, and 6, a middle frame of a mobile phone includes a middle frame body 2 made of an easily deformable material, which may be a metal material or a plastic material, and the middle frame is preferably made of a plastic material.

The inner wall of the middle frame body 2 is provided with a mounting groove 21 facing the inside of the middle frame body 2, and a piezoelectric ceramic piece 4 is fixedly arranged in the mounting groove 21. The section of the outer wall of the middle frame body 2 corresponding to the mounting groove 21 is defined as a pressing portion 23, and when the pressing portion 23 is pressed inward, the bottom of the mounting groove 21 can act on the piezoelectric ceramic plate 4 and deform the piezoelectric ceramic plate 4. After the piezoelectric ceramic piece 4 deforms, the electric signal is fed back to a controller (not shown in the figure) of the smart phone, the controller provides waveform excitation for the piezoelectric ceramic piece 4, so that the piezoelectric ceramic piece 4 vibrates, and the process and the control principle of the vibration of the piezoelectric ceramic piece 4 belong to common general knowledge for the technical personnel in the field, and are not described herein again.
