Abstract

Additional fields of application are provided for an electronic clock striking mechanism. In particular, a modular unit for a clock striking mechanism comprising an operating device, together with a clock circuit, and optionally a battery space, is built into a living room phono installation and connected by means of a selector circuit with a speaker. This arrangement makes possible the emission of acoustic time information synchronously with the time display of quartz-stabilized living room clocks that are potentially present, without the need for synchronization with the clock circuit in the clock striking mechanism which is also stabilized by quartz vibrations.
