Abstract
PURPOSE:To obtain an electronic timepiece capable of rapid, easy, and accurate tone tuning due to vision, by comparing a preset divided frequency with a frequency input from a microphone to each other to perform required indication. CONSTITUTION:Signal conversion corresponding to the operation of a switch 3 is performed in a matrix circuit 13, and a number corresponding to a set frequency is set to a preset circuit 12. A frequency dividing circuit 11 is controlled by this preset value, and the set frequency is displayed on a digital display part 2 through an operating circuit 16. Simultaneously, the circuit 11 generates the set frequency M and upper and lower limit frequencies H and L, and they are compared with the sound frequency of a musical instrument inputted from a microphone 4 by a comparing circuit 15, and any one among indication lamps 5 and 7 for upper and lower limits plus a coincident indication lamp 6, etc. is lit through the circuit 16. Consequently, rapid, easy, and accurate tuning, etc. due to vision are possible. Similarly, the metronome function corresponding to desired rhythm is possible also.
