Abstract

PURPOSE:To permit the compact electronic clock to ring with a desired sound by storing a semiconductor memory with sound inputted from the outside of the clock, and sounding the audio-data stored in the semiconductor memory as an alarm by using the signal from a clock circuit. CONSTITUTION:With a sound writing switch in a group of switches 8 operated, producing sound towards a microphone-speaker 12 causes the sound produced to be inputted through an amplifier 13 and an I/O selecting circuit 14 to an A/D converter circuit 15, where the sound is converted into a digital quantity, which is moreover encoded 16 and stored in the semiconductor memory 11. At an alarm time; when coincidence signal 7 is outputted, the sound data stored in the semiconductor memory 11 is encoded 17, sent to a sounding signal synthesizing circuit 18, passed through the I/O selecting circuit 14 and the amplifier 13, and sounded from the speaker 12 as an alarm.
