Abstract: An electric circuit structure of a question-and answer alarm clock includes an interface used as a transmitting interface for each unit, a display unit electrically interlocked onto the interface to show time and a question, an input unit electrically interlocked onto the interface, putting data in through an input device and showing the result via the display unit, a clock count unit electrically interlocked onto the interface and used to count the time, set the bell, and show the result by the display unit, a calculating unit electrically interlocked onto the interface and automatically generating a question when the bell rings, and showing the question by the display unit, and a control unit electrically interlocked onto the interface to access each unit. The display unit shows the question when the bell rings. The bell can be turned off only by inputting the correct answer.
