The technical scheme that the utility model adopts is; Detachable module combined digital clock with music prompting and timing function; Include CPU module, dynamically charactron, deserializer, key board unit and hummer, the CPU module is connected with the dynamic digital tube module of LED lamp on the dynamic charactron through winding displacement, the CPU module also pass through the jack line respectively with deserializer in register module, hummer be connected; The dynamic digital tube module of LED lamp is connected with register module through row's pin; Adjustment key-press module 7 is arranged in the key board unit, and adjustment key-press module 7 includes 6 independent buttons, and each independent button is connected with the CPU module through the jack line respectively.

The characteristics of the utility model also are,

The CPU module is STC89S51 or AT89S51;

The CPU module is provided with power module, and power module is by the conventional dc power supply of independent 5V～12V or through the USB interface power supply;

Register module is the 74HC164 SI PO shift register.

The beneficial effect of the utility model is,

1) the utlity model has that music is reminded and the detachable module combined digital clock of timing function is connected to form through winding displacement and jack line by the module of a plurality of standalone features; Can construct the digital clock model through the combination between each module; This equipment not only has characteristics detachable and reorganization, also has music and reminds and timing function.

2) in teaching, has certain booster action; Solved that teacher does not have teaching aid in teaching; Content of courses cavity, the student does not have material, the problem that experiment content does not enrich; For the teacher implements guide type teaching, on-the-spot teaching etc. suitable teaching equipment is provided, capable of using equipment of student is accomplished the experiment and the Course Exercise of course.
