A digital audio/video playing device includes a touch control board, a plurality of switch units disposed outside a perimeter of the touch control board, and a support plate disposed on the touch control board and switch units. The support plate includes a central portion, an intermediary portion ringing the central portion, and an outer portion ringing the intermediary portion. The central portion and the outer portion are thicker than the intermediary portion such that the intermediary portion is recessed relative to the central portion and the outer portion. The intermediary portion is disposed directly facing the touch control board. A plurality of depressible tabs are formed in the outer portion, each depressible tab corresponding to and directly facing a corresponding one of the switch units. A surface film is arranged over and covering the support plate such that a raised-recessed-raised configuration is formed.

1. A digital audio/video playing device, comprising: a casing defining an interior space;a storage device for storing audio/video data, the storage device arranged in the interior space;a display unit arranged in the interior space;a touch control board arranged in the interior space and having an input area for receiving touch input;a plurality of switch units disposed outside a perimeter of the touch control board;a support plate disposed on the touch control board and switch units, the support plate comprising a central portion, an intermediary portion ringing the central portion, and an outer portion ringing the intermediary portion, wherein the central portion and the outer portion are thicker than the intermediary portion such that the intermediary portion is recessed relative to the central portion and the outer portion, and wherein the intermediary portion is disposed directly facing the input area of the touch control board, and wherein a plurality of depressible tabs are formed in the outer portion, each depressible tab corresponding to and directly facing a corresponding one of the switch units such that depression of the depressible tab triggers the corresponding switch unit; anda surface film arranged over and covering the support plate such that a raised-recessed-raised configuration is formed comprising a raised central region corresponding to the central portion of the support plate, a recessed intermediary region ringing the central raised region and corresponding to the intermediary portion of the support plate, and a raised outer region ringing the intermediary region and corresponding to the outer portion of the support plate, wherein touch input is entered to the touch control board through the intermediary region, and switch units are triggered through the outer region. 2. The digital audio/video playing device as claimed in claim 1, further comprising a base plate, wherein the touch control board and switch units are disposed on the base plate. 3. The digital audio/video playing device as claimed in claim 1, wherein each depressible tab is defined in the support plate by forming an elongate slit leaving a small connection to support plate, thereby forming a cantilever tab that is elastically deformable. 4. The digital audio/video playing device as claimed in claim 1, wherein the switch unit comprises a thin film switch made of conductive rubber. 5. The digital audio/video playing device as claimed in claim 1, wherein the raised-recessed-raise configuration is smooth and continuous. 6. The digital audio/video playing device as claimed in claim 1, wherein the touch control board is circular. 7. The digital audio/video playing device as claimed in claim 6, wherein the touch control board is donut shaped, with a central area cut out corresponding to the central portion of the support plate. 8. The digital audio/video playing device as claimed in claim 1, wherein the central portion, the intermediary portion, and the outer portion of the support plate are circular and concentric. 9. The digital audio/video playing device as claimed in claim 1, wherein the support plate includes a peripheral portion surrounding the outer portion. 10. The digital audio/video playing device as claimed in claim 9, wherein the surface film includes a peripheral region covering the peripheral portion of the support plate. 11. The digital audio/video playing device as claimed in claim 9, wherein the surface film continuously covers the central portion, intermediary portion, outer portion and peripheral portion of the support plate. 12. The digital audio/video playing device as claimed in claim 9, wherein the peripheral portion comprises a window corresponding to the display unit. 13. The digital audio/video playing device as claimed in claim 12, wherein the surface film includes a peripheral region covering the peripheral portion of the support plate, the peripheral region comprising a cut out corresponding to the window. 14. The digital audio/video playing device as claimed in claim 1, wherein the surface film is molded into a raised-recessed-raised shape corresponding to the support plate.
