Abstract

A time-controlled tone signal is produced by electronic clock circuitry for a clock having chimes and/or an alarm system. In order to provide fully electronic storage and release of tone signal sequences, their data, such as tone frequencies and tone lengths, are stored in digital form in a memory circuit. The data is recalled from the memory with regard to time and is transformed by means of an electro-acoustic transducer into the desired sequence of tone signals.
