1. A vibration-absorbing structure for packaging a crystal resonator comprising:
a package base with a top thereof with a recess, wherein a sidewall of the package base surrounds the recess;
a resonant crystal blank having a border area, at least one serpentine connection area, and a resonant area, wherein the at least one serpentine connection area is connected between the border area and an edge of the resonant area, and the border area is arranged on the sidewall; and
a top cover, arranged on the border area, covering the recess, the at least one serpentine connection area, and the resonant area;
wherein the resonant area has a shape of a rectangle;
wherein when one end of the at least one serpentine connection area is connected to a corner and a long edge of the rectangle, another end of the at least one serpentine connection area is connected to an inner edge of the border area that is parallel and opposite to the long edge;
wherein when one end of the at least one serpentine connection area is connected to a corner and a short edge of the rectangle, another end of the at least one serpentine connection area is connected to an inner edge of the border area that is parallel and opposite to the short edge;
wherein an orthogonal projection location of one end of the at least one serpentine connection area that is connected to the rectangle onto the border area is a location where another end of the at least one serpentine connection area is connected to the border area;
wherein when two ends of a short edge or a long edge of the rectangle are respectively and orthogonally projected to the border area through two orthogonal projecting lines, the at least one serpentine connection area is completely located within an area surrounded by the two orthogonal projecting lines, the resonant area, and the border area;
wherein the at least one serpentine connection area comprises:
a first connection arm having a first end and a second end, wherein the first end is connected to the edge of the resonant area;
a second connection arm having a third end and a fourth end, wherein the third end is connected to the second end, and the second connection arm is vertically connected to the first connection arm; and
a third connection arm having a fifth end and a sixth end, wherein the fifth end is connected to the fourth end, the sixth end is connected to the border area, and the third connection arm is vertically connected to the second connection arm;
wherein when the second connection arm is arranged parallel to the long edge of the rectangle, a length of the second connection arm is equal to that of the long edge;
wherein when the second connection arm is arranged parallel to the short edge of the rectangle, a length of the second connection arm is equal to that of the short edge.
