What is claimed is: 1. A waterproof cover for an audio system, the waterproof cover comprising: a frame having an opening, two arcuate faces formed respectively on two opposite sides of the frame, two positioning legs protruding from a rear face of the frame and a waterproof pad securely attached to an inner side face of the frame; a gasket; and a shield with the gasket securely attached to an inner side of the shield and being pivotally connected to the positioning legs of the frame by two arms, each of the legs corresponding to each of the arms, in such a way that a pivotal trajectory of the shield is eccentric to the arcuate face thereby allowing the shield together with the gasket to engage the arcuate faces of the frame so that the waterproof pad is able to prevent moisture from entering the frame. 2. The waterproof cover as claimed in claim 1, wherein each of the positioning legs has a pivot seat formed on an outer side of the positioning leg to pivotally connect to the a corresponding one of the arms. 3. The waterproof cover as claimed in claim 2, wherein the shield has two extensions each being securely connected to a corresponding one of the arms. 4. The waterproof cover as claimed in claim 3, wherein each of the arms has bosses corresponding to holes defined in each extension of the shield such that after the bosses are inserted into the holes, engagement between the extension and the arm is secured. 5. The waterproof cover as claimed in claim 2, wherein a recovery force adjusting assembly is provided between each of the arms and the corresponding positioning leg to adjust a recovery force to bring the arm back to its closed position after being pivoted. 6. The waterproof cover as claimed in claim 5, wherein the recovery force adjusting assembly is provided between each of the arms and the corresponding positioning leg and includes a spring sandwiched between the arm and the corresponding positioning leg and adjusting holes defined in each of the two positioning legs so that the recovery force to the arms after being pivoted is able to be adjusted, the shield has two abutting ends extending respectively from two opposite sides of the shield, and the frame has two recesses defined in two opposite sides of the frame to correspond to the two abutting ends and to receive therein two pads so as to prevent water leakage from sides of the frame when the shield is pivoted relative to the frame. 7. The waterproof cover as claimed in claim 6, wherein the pivot seat has a pivot space defined by two limiting plates formed inside the pivot seat, and each of the arms has a stop received inside the pivot space such that the pivotal movement of each of the arms relative to the frame are limited to prevent excessive pivotal movement. 8. The waterproof cover as claimed in claim 3, wherein a recovery force adjusting assembly is provided between each of the arms and the corresponding positioning leg to adjust a recovery force to bring the arm back to a closed position after being pivoted. 9. The waterproof cover as claimed in claim 8, wherein the recovery force adjusting assembly is provided between each of the arms and the corresponding positioning leg and includes a spring sandwiched between the arm and the corresponding positioning leg and adjusting holes defined in each of the two positioning legs so that the recovery force to the arms after being pivoted is able to be adjusted, the shield has two abutting ends extending respectively from two opposite sides of the shield, and the frame has two recesses defined in two opposite sides of the frame to correspond to the two abutting ends and to receive therein two pads so as to prevent water leakage from sides of the frame when the shield is pivoted relative to the frame. 10. The waterproof cover as claimed in claim 9, wherein the pivot seat has a pivot space defined by two limiting plates formed inside the pivot seat, and each of the arms has a stop received inside the pivot space such that the pivotal movement of each of the arms relative to the frame are limited to prevent excessive pivotal movement. 11. The waterproof cover as claimed in claim 8, wherein the pivot seat has a pivot space defined by two limiting plates formed inside the pivot seat, and each of the arms has a stop received inside the pivot space such that the pivotal movement of each of the arms relative to the frame are limited to prevent excessive pivotal movement. 12. The waterproof cover as claimed in claim 4, wherein a recovery force adjusting assembly is provided between each of the arms and the corresponding positioning leg to adjust a recovery force to bring the arm back to a closed position after being pivoted. 13. The waterproof cover as claimed in claim 12, wherein the recovery force adjusting assembly is provided between each of the arms and the corresponding positioning leg and includes a spring sandwiched between the arm and the corresponding positioning leg and adjusting holes defined in each of the two positioning legs so that the recovery force to the arms after being pivoted is able to be adjusted, the shield has two abutting ends extending respectively from two opposite sides of the shield, and the frame has two recesses defined in two opposite sides of the frame to correspond to the two abutting ends and to receive therein two pads so as to prevent water leakage from sides of the frame when the shield is pivoted relative to the frame. 14. The waterproof cover as claimed in claim 13, wherein the pivot seat has a pivot space defined by two limiting plates formed inside the pivot seat, and each of the arms has a stop received inside the pivot space such that the pivotal movement of each of the arms relative to the frame are limited to prevent excessive pivotal movement. 15. The waterproof cover as claimed in claim 12, wherein the pivot seat has a pivot space defined by two limiting plates formed inside the pivot seat, and each of the arms has a stop received inside the pivot space such that the pivotal movement of each of the arms relative to the frame are limited to prevent excessive pivotal movement. 16. The waterproof cover as claimed in claim 1, wherein a recovery force adjusting assembly is provided between the each of the arms and the corresponding positioning leg to adjust a recovery force to bring the arm back to a closed position after being pivoted. 17. The waterproof cover as claimed in claim 16, wherein the recovery force adjusting assembly is provided between each of the arms and the corresponding positioning leg and includes a spring sandwiched between the arm and the corresponding positioning leg and adjusting holes so that the recovery force to the arms after being pivoted is able to be adjusted, the shield has two abutting ends extending respectively from two opposite sides of the shield, and the frame has two recesses defined in two opposite sides of the frame to correspond to the two abutting ends and to receive therein two pads so as to prevent water leakage from sides of the frame when the shield is pivoted relative to the frame.
