The present invention relates to an acoustic device, and more particularly, to a timer and a sleep continuous control circuit for continuously operating a sleep and a timer of a built-in sound device.

Currently, the domestic and international sound equipment, which is produced and marketed, has a built-in clock for performing a sleep operation and a timer as shown in FIG. 1, and will briefly describe the operation of FIG.

First, when adjusting the time, set the reset / timer / sleep function selector switch (S5) to the reset position and press the set switch (s4) and the time adjustment switch (S1) once each time. Up (UP) bar is adjusted, press the switch (S1) for more than 3 seconds to adjust continuously up.

In the case of minute adjustment, press switch S4 and minute adjustment switch S2, and when the switch S2 is pressed for 3 seconds or more, it is continuously adjusted upward by 1 minute in the same way as switch S1. Presses the switch S4 and the second adjustment switch S3. In the case of continuous operation, the switch S3 is pressed for 3 seconds or more as described above.

On the other hand, when the slip is operated, when the switch S5 is set to the slip position and the set switch S3 is pressed, "00" is displayed on the LCD.

At this time, if you press the switch (S1), it is adjusted upward from 1 minute to 59 minutes, and if you press the switch (S2), it is adjusted downward (down) from 59 minutes to 1 minute. When the switch S3 is pressed in the state, the sleep operation is started.

At this time, when the switch S4 is pressed, the remaining time is displayed on the LCD, and when the switch S4 is turned off, the current time is displayed.

In addition, when the pushbutton switch PB1 is turned on, since the main power supply of the acoustic device applies a bias voltage to the base of the transistor Q1 at terminal 7 of the clock circuit IC1, the acoustic device continues to operate. When the set time elapses, a bias voltage is applied to the base of the transistor Q1 at the terminal 7 of the clock circuit IC1 so that the acoustic device continues to operate. When the set time elapses, the bias current from the seventh terminal of the clock circuit IC1 does not flow, so that the power supply to the sound equipment set power supply B ⁺ is stopped, and thus all operations of the sound equipment set are stopped.

When the timer is operated, when the switch S5 is set to the timer position and the switch S4 is pressed, the set time is displayed on the LCD and the time is artificially set using the time adjustment method described above. Turn on the rear pushbutton switch (PB1). When the set time is reached, a bias is applied to the base of the transistor Q1 at the seventh terminal of the clock circuit IC1 to operate the acoustic device. Note that, in the eighth terminal of the clock circuit (IC1) is stopped because of a sounder set power (B ⁺⁾ bias of the transistor (Q1) if and output an alarm signal in a predetermined time, the elapsed settling time (e.g. 60 minutes) It stops and stops all operation.

As described above, the conventional timer / slip control circuit is configured to perform only a single operation, so that the consumer has to operate the sleep before going to bed and operate the timer at the same time without waking.

Therefore, in view of the above situation, the present invention operates the sleep before going to bed so that the timer operates automatically at the time set before the sleep operation even if the timer is not set separately after the sleep is turned off after a predetermined time has elapsed. To provide a timer and a sleep continuous control circuit of the purpose.

The present invention for achieving the above object is a sleep continuous operation unit for continuously operating the sleep, a timer continuous operation unit for continuously operating the timer, a pulse supply unit for providing a pulse to these operation units, these sleep and timer continuous And a reset unit for resetting the clock circuit after the operation unit is completed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 shows a timer and a sleep continuous control circuit diagram of an acoustic device according to the present invention, in which the same reference numerals as in FIG. 1 denote the same parts.

The pulse supply unit 10 according to the present invention is composed of a plurality of JK flip-flops (FF1-FF3) to drive the slip continuous operation unit 11 consisting of transistors Q3, Q4, and Q8 and at the same time, the transistor The timer continuous operation unit 12 of (Q5) is switched to perform the continuous operation of the timer.

The transistors Q6 and Q7 constitute a reset section 13 for automatically resetting the clock circuit IC1 when the sleep and timer operations are completed. Reference numerals R7-R29 are resistors and PB2 are push buttons. Mark the switch.

The operation of the present invention configured as described above will be described.

The present invention can be controlled manually and automatically, the manual operation is the same as the conventional technology described with reference to Figure 1, so for the sake of simplicity of the description will be omitted for the sake of simplicity and only the automatic operation refer to Figure 2 This will be described.

First, push button switch PB1 is turned on, push button switch PB2 is turned on and separated from adjustment of switch S5.

In addition, since the clock circuit IC1 has a memory function, the clock and circuit IC1 read the preset time and do not need to be adjusted again. If the time is adjusted again, the same method as described with reference to FIG. 1 is performed.

When the set time is determined, the switch S4 is turned on and the switch S3 is pressed to start sleep. At this time, the transistors Q3 and Q4 supply the set power source B ⁺ from the power source + Vcc. The output of the transistor Q8 is turned on via the resistors R8 and R10 to the transistors Q3 and Q4 and input to the clock circuit IC1 to enable resetting at the time setting.

In the 7th terminal of the clock circuit IC1, when a pulse is outputted when it is turned on and input to the clock pulse terminal CK of the flip-flop FF1, the output (out1) of the flip-flop FF1 becomes high. This output out1 is applied to the clock pulse terminal CK of the flip-flop FF2. At this time, since the output out2 of the flip-flop FF2 becomes low, the transistor Q8 is turned on so that the transistor Q3 is turned on. , Bias is continuously supplied to (Q4).

When the predetermined time is over, since the pulse is not output at the terminal 7 of the clock circuit IC1, the transistor Q1 is turned off and the transistor Q2 is also turned off accordingly, so that the set power supply B ⁺ of the acoustic device is turned off. This is not supplied and the slip operation is completed.

When the timer time is again set, a pulse is output from the seventh terminal of the clock signal IC1, so that the transistor Q1 is turned on and a low signal is applied to the base of the transistor Q2 as the transistor Q1 is turned on. Q2 is turned on again, and the set power source B ⁺ is applied to start the timer operation.

In this case, since the second pulse is applied to the clock terminal CK of the flip-flop FF1, the output out2 of the flip-flop FF2 becomes high, and the transistor Q8 is turned off so that the transistors Q3 and Q4. ), The bias circuit is interrupted, the sleep circuit is interrupted, and since the output (out1) of the flip-flop (FF1) is low, the transistor (Q5) is turned on, so the signal source of the switch (S4) is connected to the clock circuit (IC1) to reset the time. Will lead to.

When the predetermined time is over, since no signal is applied to the base of the transistor Q1, the set power source B ⁺ is stopped and all operations are stopped. At this time, since the low signal is output at the output out3 of the flip-flop FF3, the transistor Q7 is turned on and the clock circuit IC1 is reduced to the reset position which is initial data. That is, it automatically switches to the initial reset position.

The present invention operating as described above is characterized in that the conventional manual operation as shown in FIG. 1 can be performed while the sleep and the timer can be performed simultaneously.
