Abstract

PURPOSE:To obtain an alarm tone which varies incidentally, by constituting a time signal device with three sections: the weather detector, the oscillator and the watch each and thus securing a change for the level, strength or tone of the signal sound generated as the time signal according to the weather on that day. CONSTITUTION:The device consists of the weather detector 1, the oscillator 2 and the watch 3. The barometer 11 is used for the detection part of the detector 1. In general, the fine and bad weather days are in the high and low atmospheric pressure each. Thus the contact 12 is provided to the barometer 11 to be closed when the atmospheric pressure lowers. The oscillator 2 forms a sound generating device which produces a tone at the fixed time of the watch 3, and consists of the positive feedback oscillation circuit. Thus the oscillator 2 varies the time constant of the capacitor circuit 21 and then the tone of oscillation. In ease the capacitor 211 of one side in the circuit 21 is used, the oscillation similar to the note of a bird is produced. And the tone similar to the tone of a frog is obtained in case the capacitors 211 and 212 are connected in parallel to each other. And the contact 31 is provided to the watch 3 to produce the time signal.
