Description

Crystal clock giving the correct time by famous music with dual-sound track

Two-channel masterpiece in music time signal clock of the present utility model is used for family, office and other public place timing, gives the correct time, and it is the masterpiece in music time signal clock that is combined with advanced person's cmos digital integrated circuit and the storer in the computer by quartz analog clock.

Masterpiece in music time signal clock technical problem underlying is how to make its reliable operation, and is easy to use, and technology is simple and reduce cost.More existing music time signal clock is used complicated special IC sheet or is used the micro processor controls music storage, uses hardware more, and technology is complexity, and production cost is higher, and the purchase special IC is had any problem, and is difficult for popularizing inconvenient maintenance.

Disclosed according to patent DE3147-534-A " the music time signal clock that has tone control circuit " is to adopt counter and two kinds of storeies to be used, can key in and requiredly perform music the time in storer, make its with counter institute timing between be consistent with the control music playing.Melody is to be made of specialized circuitry and storer.This music time signal clock should repeatedly use in the timing.Employing hardware is more, and circuit is complicated, and it is not too convenient to use, and is unwell to general family and uses.

The two-channel masterpiece in music time signal clock that the utility model adopts unitized cmos digital integrated circuit chip, music storage circuit and the quartz analog clock of standard to combine reaches similar music time reporting function than complicated circuit with simple electronic circuit.In order per hour to give the correct time once with per half an hour, make two cover sound equipment sound channel systems especially, its musical film and loudspeaker are respectively arranged.It is simple to do technology like this, does not disturb mutually, the components and parts wide material sources, and cost is lower, produces easily.Two cover sound systems can produce the sound equipment of different tone colors, tone and different melodies, make the people be easy to differentiate institute and call time, and the sensation of novelty is arranged.

The circuit order of connection in the utility model is: quartz analog clock---amplify and transducer---counter---time/half divider---music storage in parallel---amplifier---loudspeaker.Circuit is parallel music storage, amplifier and the loudspeaker sound Circuits System of two covers.Wherein sound system is with corresponding 12 hours of 12 first masterpieces in music one by one, per hour plays a song, and the first bent selected songs corresponding with certain hour are selected with selected songs keyswitch N; Another sound system is to play another fixedly melody per half an hour.Selected a unit-pulse signal that makes the simple pps pulse per second signal of circuit as counter in the line for use, and make per hour self-zeroing and obtain circulation of counter with digital circuit feedback, also triggered simultaneously music storage, make its outputting music signal, reach the per half an hour and the purpose of per hour giving the correct time.When needing peace and quiet when not needing to give the correct time, then available K switch disconnects sound system.

The utility model has following accompanying drawing:

Fig. 1 is a functional-block diagram of the present utility model.

Fig. 2 is an embodiment of the present utility model.

As described in Figure 1, the pulse signal that produces by quartz analog clock 1 be by frequency divider in the clock 32768Hz of crystal oscillator output is carried out frequency division and the 1Hz pps pulse per second signal, and suitably handle by signal processor 2, its antijamming capability is strengthened.Signal magnification changer 3 strengthens signal and level is changed, and makes it be suitable for the needs of CMOS integrated circuit input pulse.4 pairs of inputs of counter pps pulse per second signal counting is to counting 1800 pulse signals half an hour, to per hour then counting 3600 pps pulse per second signals.This two numerical value is counted with same counter 4.The time spent/half divider 5 exports per half an hour and control signal hourly respectively, and feed back to counter by control signal hourly, and make counter return zero, thus carry out the Automatic Cycle counting.12 first masterpieces in music first bent with 12 hours in certain hour corresponding selected songs, carry out with selected songs pushbutton switch 6, also available this switch is calibrated the time of giving the correct time.Half an hour and control signal hourly to the music storage 7 and the 10 input trigger pulses of two sound systems, make it export corresponding music electrical signal respectively.Though this music electrical signal has driving circuit in the music storage output circuit, but power is still less, deficiency so two sound equipment passages also add electronics power amplifier 8 and 11 separately, makes its acoustic signal reach satisfied numerical value so that loudspeaker and piezoelectric ceramic piece send enough sound equipments.Acoustic signal after the amplification drives loudspeaker or piezoelectric ceramic piece 9 and 12 separately respectively, thereby produces melodious melody.

Fig. 2 is an embodiment of the present utility model: export pps pulse per second signal after the pulse signal through amplifying conversion is added to 4070 additions, send into counter 4040, count value by 4040 outputs is binary 8421 yards, export thus 1800 and 3600 pulse per second (PPS)s countings through two four inputs with door, with its with and must half an hour and control signal hourly control the sound system of two sound channels.When needing peace and quiet, then K switch can be disconnected when not needing to give the correct time.

Claims (5)

1, a kind of two-channel masterpiece in music time signal clock, feature of the present utility model is to adopt quartz analog clock to add corresponding 12 hours of the 12 first masterpieces in music of digital integrated circuit control music storage and control another first fixedly melody per half an hour, per hour make with per half an hour playing music give the correct time.
