Definitions

  • time-piece have been of such a type that they are prosounds with different frequencies.
  • Another object of the present invention is to provide an electronic timepiece with a time signalling device wherein the time signalling device produces periodical and alternate sounds with different frequencies.
  • An electronic timepiece with a time signalling device comprises a divider including a plurality of counting-down devices connectedin a cascade. manner for dividing a high frequency signal from a standard oscillator into a standard time signal of low frequency, and a switching device for operating said time signalling device at a set time, one of the output signals with a predetermined frequency produced from one of the output terminals of said counting-down devices being selectively applied to. said time signalling device, thereby producing a time signalling sound with an audible frequency.
  • the counting down device may be, for example, a bistable multivibrator for dividing the frequency of a signal into half the frequency.
  • a plurality of output signals with a predetermined frequency produced from the output terminals of said counting down devices are periodically and alternately applied to said time signalling device under the control of signal produced'from one of the output terminals of said counting-down devices, thereby producing a time signalling sound witha plurality of tones.
  • FIG. 1 there is shown a circ'uit'diagram wherein a quartz oscillator produces a time signal of high frequency which is successively divided into a signal of k diagram showing an arrangement of FFn in a divider Ill.
  • the divided output signal generated from the divider 11 is applied to a time counter 12 for. counting time signals for seconds, minutes and hours (and including ifdesired, a date or day).
  • the output signal generatedin the counter 12 is applied to a display means 13 including a decoder and driver to display time.
  • the circuit further includes a signal time memorizing register 18, an electronic switch controlling circuit 17 by which an electronic switch S is closed when the output generated from the counter 12 coincides with that from the register 18, and a time signalling device 16 comprising an amplifier 14 and a speaker 15.
  • the output frequency signals required for the time signalling sounds may be selected from the flip-flop circuits FF,, FF FF FF FF or FF, (FR, FF ,FF FF, not being shown in FIG. I).
  • the output signal of circuit 19 is alternately supplied with frequency a or b in response to the periodical switching selection due to the output signal of the last stage of the divider l I.
  • the frequency of the output signal a fromthe flip-flop circuit FF is, for example, 2 Hz (4,096 Hz) while the frequency of the output signal b from the flip-flop FF circuit is 2.” Hz (2,048 Hz) when the oscillator 10 produces, for example, an output signal of. frequency 2" Hz (16,384 Hz).
  • the output signal from the flip-flop FF circuit is used as the input signal to the time signal controlling circuit 119, the output signal from circuit 19 is l Hz in frequency.
  • control signal applied to the time signal controlling circuit 19 can be changed in frequency by switching the output terminal and flip-flop circuit of the divider (for example, from the output terminal d of the flip-flop FFn to the output terminal c of the flip-flop FFn-l thus insuring the production of various kinds of sounds.
  • the electronic switch controlling circuit shown operates the electronic switch S to signal at a predetermined time.
  • the time signalling device ac-" cording to the invention brings about many advantages as follows: signal sounds having a different kind of audible frequency can be selected according to the use mode because the time signal is selected from suitable output terminals of flip-flop circuits in the divider. A stable time signalling sound can be obtained because of the use of a frequency generated from a quartz oscillator. Further, it is possible to signal exactly the time to be signalled after the closing of the electronic switch because the time is memorized by the signal time memorizing register. Further, any combination of two or' more output signals having a desired frequency can be periodically and alternately generated from the divider under control of the output signal produced from any other terminal of the divider for application of the signal to the time signalling device.
  • each said counting-down device is a bistable multivibrator for dividing the frequency applied thereto in half.
  • said divider includes a plurality of output terminals connected to at least some of said countingdown devices and means by which the frequencies produced at said output terminals are periodically and alternately applied to said time signalling device under control of a signal produced from one of the output terminals of said counting-down devices, thereby producing a time signalling sound with a plurality of tones.
  • An electronic timepiece comprising a counter and display means connected in series to said divider.
  • An electronic timepiece comprising register means and switch controller means coupled to each other, said switch controller means being coupled to said switching device.
