专利汇可以提供Voice generating timer专利检索,专利查询,专利分析的服务。并且PURPOSE: To inform users the residual time through a voice when the residual time reaches a set value after a timer actuates by adding a voice generation facility to a timer.
CONSTITUTION: A user sets a timer time by means of a dial 1 and sets a residual time of a voice count starting by means of a dial 2. And a switch SW is pressed to actuate a self timer. At this time, an operation circuit ALU resets a flip-flop F1 and then, reads a set value of the timer time from the dial 1 and writes it in a memory circuit RAM and performs a subtraction in the memory circuit RAM at every constant time. A coincidence circit CC always compares the content of the memory circuit RAM and the value of the dial 2 and when both coincide, a flip-flop F2 is set, and here, with this, a voice generation circuit VC takes a voice information corresponding to the data being sent from the operation circuit ALU out of a fixed memory circuit ROM, thus, supplying it to a speaker SP.
