An AC and DC dual-purpose power supply circuit which simultaneous provides operating voltage for the device, a controlled recorder starting and time delay switching-off circuit which uses a relay < 1 > to provide power supply for the recorder whose PLAY key is pressed down and control circuit which is switched on and switched off by a controlled amplifier are arranged in the printing circuit plate. A programming device or a button instantly starts the driving circuit of the relay, the audio output of the recorder triggers monostable, and the output keeps a breaker J< 1 > to be attracted through a driver. The utility model has the conspicuous advantages of novel design and the music appreciation in the rest time.
Description
The utility model belongs to suggestion device, relates to the daily schedule suggestion device that melody is play in a kind of timing.
Daily schedule suggestion device by programmable device control, most with the electric bell the tinkle of bells as cue, the sound point is strict ear-piercing and unexpected, for a long time it, people will be difficult to bear, and utilize the simulated sound of music IC to replace the tinkle of bells for this reason, be to use frequent suggestion device prompting mode commonly used, yet its melody melody can't with real melody mutually this, and inconvenient repeat playing is appreciated for people.
The utility model is intended to disclose a kind of daily schedule suggestion device of playing melody with graceful melody for the timing of replacement the tinkle of bells of appreciating and analog music sound.
Above-mentioned purpose is achieved through the following technical solutions: in the housing 2 that is provided with panel 1 printed circuit board (PCB) that comprises following circuit is housed, these circuit are:
AC and DC double-purpose electric source circuit---rectifying voltage regulator and battery pack provide operating voltage for this device simultaneously;
Controlled sound-track engraving apparatus starts, time-delay shutdown circuit---relay J 1 provides working power for the controlled sound-track engraving apparatus of pressing the PLAY key, programmable device B or hand push button KN provide the driver of voltage instantaneous starting relay J 1, the sound signal of controlled sound-track engraving apparatus output triggers monostalbe trigger, and its output is kept relay J 1 adhesive through driver;
Controlled sound amplifier opens left alone without help control circuit---and controlled recorder audio output connects the sound amplifier input end, controlled sound amplifier AC power is provided by relay J 2, and the control signal of its driver is taken from the controlled sound-track engraving apparatus startup of attracting state, the relay J 1 in the time-delay shutdown circuit.
Controlled sound-track engraving apparatus starts, monostable in the time-delay shutdown circuit is touched out device by time base circuit ICNE555 and transistor T 4, T5 constitutes, controlled recorder audio output is through relay J 1 normally opened contact J1---and 1, capacitor C 7 connects the T4 base stage, this utmost point also is connected to by resistance R 8, potentiometer W2, the triggering level that resistance R 9 is in series is adjusted branch road, the T4 grounded emitter, collector connects ICNE555 pin 2 and T5 base stage, T5 grounded collector, emitter connects ICNE555 pin 6,7 and resistance R 11, the time constant branch road that potentiometer W3 and capacitor C 8 constitute, ICNE555 pin 3 connects transistor T 6 base stages through isolating diode D2, the T6 base stage is respectively through resistance R 13, R14 is fastened on the button switch 6 and the programmable device B output terminal that is contained in the housing 2 on the panel, another termination noble potential of button switch, transistor T 6 collector connecting relay J1 windings, its normally opened contact J1---2 strings are pressed between power supply "+" utmost point and terminal A, terminal B ground connection;
Controlled sound amplifier opens the relay J 2 of left alone without help control circuit, its winding connects transistor T 7 collectors, the T7 base stage is through resistance R 16 connecting terminal A, the T7 grounded emitter, the J2 winding also is connected to the red light emitting diodes LED1 that is installed on the panel, J2 normally opened contact J2---1, J2---, and 2 are serially connected in respectively between this device AC power and the accessory power outlet CZ.
Below with drawings and Examples explanation the utility model.
Accompanying drawing 1 the utility model structural representation
Accompanying drawing 2 the utility model electrical schematic diagrams
Drawing explanation: 1 panel, 2 housings, 3 programmable device B, 4 red light emitting diodes, 5 edge look light emitting diodes, 6 pushbutton switches.
The utility model example structure comprises that the programmable device B of liquid crystal time showing and button is installed in this device case as shown in Figure 1, and terminal A, the B of output dc voltage and the socket CZ of output AC voltage are located at housing back shroud (not shown)
Circuit structure of this device and principle of work as shown in Figure 2, ac-dc dual power supply by series type direct current regulation source and battery pack E through regulator block 7805 simultaneously for this device provides 5V operating voltage, guarantee the continuous working of this device.Manually the square-wave signal of button switch KN or programmable device B output makes transistor T 6 instantaneous conductings, relay J 1 adhesive, normally opened contact J1---2 through terminal A, B makes the controlled sound-track engraving apparatus of pressing the PLAY key get electric work, make transistor T 7 conductings simultaneously, relay J 2 adhesives, its normally opened contact J2---1, J2---2 make socket CZ connect the AC power sound amplifier promptly works, the sound signal of controlled sound-track engraving apparatus output is often opened contact J1 by terminal C---1 and capacitor C 7 make transistor T 4, the T5 conducting, monostalbe trigger ICNE555 upset, the high level of pin 3 outputs is kept the T6 conducting, record, sound amplifier works on and plays the melody of Vidio tap edit.When the melody broadcasting of the expression stipulated time that programmable device is set finishes, T4, T5 will end, power supply charges to capacitor C8 through resistance R 11, potentiometer W3, when current potential was increased to 2/3Vcc, 3 upsets of ICNE555 pin ended T6 for low level, relay J 1 discharges, controlled sound-track engraving apparatus and the shutdown of controlled sound amplifier, this routine delay switching-off time is decided to be 20 seconds, can guarantee less than the reliable and stable work of this circuit in stop time in 20 seconds the every first melody and the interval time between each melody.
The controlled sound-track engraving apparatus of the utility model should be selected the sound-track engraving apparatus with automatic turn over function for use, and its program control time range can satisfy more occasion needs.
The utlity model has modern design, time of having a rest can for melody appreciate significantly excellent The point.
