Piezoelectric assembly, electronic device and assembly process for piezoelectric assembly

An electronic device, comprising:

• a display screen having a back surface facing an inside of the electronic device;
• and
• a piezoelectric assembly coupled to the back surface and comprising:
• at least two piezoelectric components, each of the at least two piezoelectric components comprising:
• a main body portion having a set edge, a first surface, and a second surface opposite the first surface, main body portions of the at least two piezoelectric components being stacked, and
• a connecting portion extending from the set edge in a direction away from the main body portion and having a first surface and a second surface opposite the first surface, the first surface of the main body portion and the first surface of the connecting portion being a positive electrode, the second surface of the main body portion and the second surface of the connecting portion being a negative electrode, first surfaces of connecting portions of the at least two piezoelectric components face a same direction, and the connecting portions of the at least two piezoelectric components being spaced apart along the set edge;
• a positive circuit board arranged on the first surface of the connecting portion;
• and
• a negative circuit board arranged on the second surface of the connecting portion.

An assembly process for a piezoelectric assembly, comprising:

• providing at least two piezoelectric components, wherein each of the at least two piezoelectric components comprises a main body portion and a connecting portion protruding from a set edge of the main body portion;
• a first surface of the main body portion and a first surface of the connecting portion are a positive electrode, and a second surface of the main body portion and a second surface of the connecting portion are a negative electrode;
• the first surfaces are opposite to the second surfaces;
• stacking main body portions of the at least two piezoelectric components to cause a first surface of one piezoelectric component of the at least two piezoelectric components to face a second surface of another piezoelectric component of the at least two piezoelectric components, and connecting portions of the at least two piezoelectric components are staggered along the set edge;
• and
• coupling the first surface of the connecting portion to a positive circuit board and coupling the second surface of the connecting portion to a negative circuit board, wherein different connecting portions are coupled at different positions of the positive circuit board, and different connecting portions are coupled at different positions of the negative circuit board.
