Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
In an electronic clock striking mechanism having a control circuit including a detector for detecting a real-time related signal and a signal transducer circuit which is actuated to produce an acoustic time indication in response to detection of a predetermined time signal, the improvement wherein said control circuit is built into a loudspeaker housing for a conventional diverse element commonly found in a dwelling and is operatively connected to a speaker in said housing to emit the acoustic time indication through said speaker upon actuation of said signal transducer circuit, and further including a sensor circuit for sensing a signal from said diverse element and for selectively disconnecting said signal transducer circuit from said speaker when a signal is sensed.
Claim 2
Dependent Claim
120 words
In an electronic clock striking mechanism having a control circuit including a detector for detecting a real-time related signal and a signal transducer circuit which is actuated to produce an acoustic time indication in response to detection of a predetermined time signal, the improvement wherein said control circuit is built into a loudspeaker housing for a conventional diverse element commonly found in a dwelling and is operatively connected to a speaker in said housing to emit the acoustic time indication through said speaker upon actuation of said signal transducer circuit, and further including a sensor circuit for sensing a signal from said diverse element and for selectively disconnecting said signal transducer circuit from said speaker when a signal is sensed.
Claim 3
Dependent Claim
50 words
The electronic clock striking mechanism of claim 1 wherein said loudspeaker housing also incorporates a counter for producing said real-time related signal in response to a timing signal, and a time clock including a digital display unit, said time clock being connected to said counter in parallel with said detector.
Claim 4
Dependent Claim
36 words
The electronic clock striking mechanism of claim 1 wherein said sensor circuit includes a time delay stage for maintaining said signal transducer circuit disconnected from said speaker a predetermined time period after a signal is sensed.
Claim 5
Dependent Claim
16 words
The electronic clock striking mechanism of claim 1 wherein said diverse element is a phono system.
Claim 6
Dependent Claim
30 words
The electronic clock striking mechanism of claim 4 wherein said phono system includes a clock, and a timing signal from said clock is supplied to said striking mechanism control circuit.
