Claims

[Claims for Utility Model Registration] A timekeeping mechanism unit that generates a phonetic command signal at a fixed time, a phonetic mechanism unit that can produce a 12-tone scale, and each tone of the 12-tone scale and each corresponding to the fixed time. The correspondence with the time is memorized, and every time the phonetic command signal is received, after the basic tone which is one of the 12 tone scales is pronounced, the scale constituent notes corresponding to the time are pronounced. A 12-tone scale phonetic device, comprising: a phonetic control mechanism section that controls the phonetic mechanism section;
