PURPOSE:To provide a useful simplified clock even for people having sight obstruction, by displaying a corrected time and informing present time with different tone in frequency and continuant. CONSTITUTION:Four demultiplied outputs are generated from a demultiplying part 2 through a controlling part 5 and from an informing generator 3 being charged digital data in corresponding present time from a clock part 4, and four different modulled signals in frequency and continuant are generated in corresponding the four demultiplied outputs by closing a switch S1. This annunciating signal is formed with a spare signal in the first frequency and a set continuant, a distingushing signal in different continuant for morning and afternoon and in the second frequency, and present timing signals in different continuant numbers corresponding hour and minute for present time and in different inherent frequency for the third and the fourth. Further, in the same way for opening the switch S1, a desirable pronouncing signal is generated and is annunicated present time by hearing. In same are cases of the confirmation and correction for the present time are made. It is a useful simplified clock even for people having sight obstruction. |
