Abstract
A digital audio/video playing device includes a support plate forming a plurality of depressible tabs. Each tab is formed by forming an elongate slit surrounding the tab with a small connection with the support plate to form a cantilever, elastically deflectable tab. A plurality of switch units and a touch control board are arranged between a base plate of the playing device and the support plate. A surface film is attached to the support plate and has a continuous raised-recessed configuration, including a smoothly-raised external ring section and a touch-control internal ring section to allow a user to depress the depressible tabs of the support plate and to operate the touch control board via the surface film.
