Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an electronic clock with an alarm function used in alarm clocks and the like.

[Prior art and its problems] Conventionally, alarm clocks used are:
A time is set in advance to generate a warning sound, and when the current time matches this set time, a warning sound is generated, and a person who is woken up by this warning sound presses the warning sound stop switch. The warning sound can be stopped by operating the device.

However, simply pressing the alarm stop switch to stop the alarm sounds is too easy, and there is a risk that the switch will be operated without the user being fully awake, and the alarm may be stopped when the alarm is stopped. in,
It did not work well as an alarm, as I ended up falling asleep again.

Therefore, to compensate for this inconvenience,
Some devices are configured to stop the alarm sound by pressing the alarm stop switch and then generate the alarm sound again after a predetermined period of time has elapsed.

However, if the warning sound is repeated in this way, the time at which the warning sound is set to occur tends to be inaccurate, and you may not be able to wake up at the desired time. but,
If the user forgets to perform an operation to prevent the subsequent sound alarm operation, the sound alarm will be emitted every time a predetermined period of time elapses, which has the drawback of significantly shortening the battery life, especially in devices that use a battery as a power source.

[Purpose of the invention] This invention was made in view of the above circumstances.
To provide an electronic watch equipped with a sound function that can be expected to have an effective wake-up effect by making it difficult to stop the sound.

[Key points of the invention] The electronic clock equipped with a sound alarm function according to this invention is designed to generate a sound when a preset scheduled time of sound matches the current time, and is designed to generate a sound when a preset scheduled time of sound matches the current time. At least one sound stop switch
In addition to setting the effectiveness of one operation, the generation of the warning sound can be stopped by operating the corresponding switch.

[Embodiment of the invention] An embodiment of the invention will be described below with reference to the drawings.

A time set key 3 is arranged along the display section 2. The time set key 3 in this case consists of an hour set key 3a, a minute set key 3b, a time set mode key 3c, and a tone set mode key 3d.

The top surface of the watch body 1 has a slit-shaped tone setting hole 4. This tone setting hole 4 allows a switch piece 5 to be inserted and removed, and a set switch 41, which will be described later, is incorporated therein, and when the switch piece 5 is inserted, the set switch 41 is turned on. Here, the switch piece 5 has a tip portion formed as a plate-shaped insertion portion 51 inserted into the slit-shaped tone setting hole 4, and a proximal portion formed as a knob portion 52.

The watch body 1 has a plurality of slit-shaped sound stop holes 6, numbered #1 to #n, formed at equal intervals along the lower circumferential surface. A stop switch 61, which will be described later, is built into each of these sound stop holes 6, and when the above-mentioned switch piece 5 is inserted, the corresponding stop switch 61 is turned on.

Next, FIG. 2 shows the circuit configuration of the same embodiment.

In the figure, reference numeral 11 denotes a clock circuit, and this clock circuit 11 has a control section for setting the current time and the scheduled alarm time. This clock circuit 11 is supplied with key input data of the time setting key 3 described above.

The current time data set by the clock circuit 11 is written into the current time storage section 12, and the alarm time data is written into the alarm time storage section 13. The data stored in these storage units 12 and 13 is stored in a matching circuit 14.
is given and a match is determined. Then, the coincidence output of the coincidence circuit 14 is given to one terminal of the AND gate AND1.

On the other hand, due to the ON operation of the set switch 41 incorporated in the sound alarm set hole 4 described above, an "H" output is given to the S terminal of the flip-flop 15, and is also given to the R terminal of the flip-flop 15 via the inverter INV1. And given to the gate AND2.

The output of the Q terminal of the flip-flop 15 is given to the other terminal of the AND gate AND1, and
It is applied to the R terminal of the counter 16.

The output of the AND gate AND1 is applied to the S terminal of the flip-flop 15. The output of the Q terminal of the flip-flop 17 is output from the buzzer drive circuit 18.
is applied to the ES terminal of the AND gate.
given to AND2.

Here, the buzzer drive circuit 18 drives the buzzer 19, and also controls the volume of the buzzer 19 according to the level of the voltage V controlled by the voltage control circuit 20. Also, the AND gate AND2 is set to "H" via the set switch 41.
is given, and an "H" output is given from the Q terminal of the flip-flop 17, and the clock φ is output, and this output is sent to the counter 2.
It is given to the C terminal of 1.

Counter 21 counts the clock φ applied via AND gate AND2, and provides this count value to decoder 22. The decoder 22 has an output terminal #1 corresponding to the count value of the counter 21,
Output is generated at #2,..., #n.

The output of each output terminal of the decoder 22 is given to one terminal of AND gates AND11, AND12, . . . AND1n. These and gates AND11,
The other terminal of AND12,...AND1n is #1 as described above.
Stop switches 61 incorporated in the sound stop holes 6 of ~#n are connected to each other separately. When these stop switches 61 are turned on, they output "H" to the corresponding AND gates AND11, AND12, . . .
It is applied to AND1n and also to the C terminal of the counter 16 via OR gate OR1. This counter 16 is incremented by the operation of the stop switch 61, and this count value is given to the decoder 23. The output of the decoder 23 is then given to the voltage control circuit 20.

Here, the voltage control circuit 20 controls the voltage V supplied to the buzzer drive circuit 18 by the output of the decoder 23.
The level of this is gradually increasing.

The outputs of the AND gates AND11, AND12, . . . AND1n are applied to the R terminal of the flip-flop 17 via the OR gate OR2.

Next, the operation of the embodiment configured as described above will be explained.

First, the current time is set by operating the time set key 3. In this case, operate the time set mode key 3c to enter the current time set mode. Then, the current time is displayed on the display section 2 using the hour setting key 3a and the minute setting key 3b, and after confirmation, the current time is set. After this, the current time is output from the clock circuit 11 and displayed on the display section 2. In addition, the clock circuit 11
The current time output is written to the current time storage section 12 while being updated at predetermined intervals, for example, every minute.

Next, set the scheduled alarm time. in this case,
Operate the alarm time set mode key 3d together with the time set mode key 3c to enter the alarm time set mode. Then, the scheduled alarm time is displayed on the display section 2 using the hour setting key 3a and the minute setting key 3b, and upon confirmation, the alarm time is set. This alarm time is written into the alarm time storage section 13.

Next, the switch piece 5 is inserted into the tone setting hole 4 on the top surface of the watch body 1. Then, set switch 4
1 is turned on, and an "H" output is given to the S terminal of the flip-flop 15 and also to the AND gate AND2. Further, an "H" output is generated at the Q terminal of the flip-flop 15, and this output is applied to the AND gate AND1 and the R of the counter 16.
given to the terminal.

The electronic clock, in which the alarm time is set in this manner and the switch piece 5 is inserted into the alarm setting hole 4, is placed near the bedside when going to bed.

From this state, when a predetermined period of time has passed and the current time in the current time storage section 12 matches the scheduled alarm time stored in the alarm time storage section 13, an output is generated from the matching circuit 14 and applied to the AND gate AND1. It will be done.
Then, an "H" output is generated from the AND gate AND1 and applied to the S terminal of the flip-flop 17, and an "H" output is generated at the Q terminal of the flip-flop 17. This "H" output is given to the buzzer drive circuit 18, and the AND gate
given to AND2.

As a result, the buzzer 19 is driven by the buzzer drive circuit 18, and a warning sound is generated. The volume of the sound of the buzzer 19 in this case is controlled by the lowest level voltage V set by the voltage control circuit 20. On the other hand, a clock φ is output from the AND gate AND2 and applied to the counter 21. The counter 21 counts the clock φ at the buzzer 1.
The person who wakes up at the sound of 9 pulls out the switch piece 5 from the alarm set hole 4, and turns on the set switch 41.
continues until it goes off.

Thereafter, when the switch piece 5 is removed from the alarm sound set hole 4 and the set switch 41 is turned off, the count value of the counter 21 at this time is given to the decoder 22, and the corresponding output terminal #1,
Outputs are generated at #2, . . . , #n. Assuming that output is currently being generated at output terminal #1,
An "H" input is given to one terminal of the AND gate AND11.

From this state, the switch piece 5 extracted from the sound alarm set hole 4 is inserted into any of the sound stop holes 6 from #1 to #n.
When the switch piece 5 is inserted into a sound stop hole 6 other than the above, the stop switch 61 corresponding to this sound stop hole 6 is turned on.
Since an "H" output is never given to the other terminal of AND11, an "H" output is never generated.

In this case, an "H" output is generated via the stop switch 61 corresponding to the sound stop hole 6 into which the switch piece 5 is inserted, and this "H" output is given to the counter 16 via the OR gate OR1. Then, the counter 16 counts up, and this count value is given to the decoder 23. The output of the decoder 23 is then given to the voltage control circuit 20. Then, the level of the voltage V supplied to the buzzer drive circuit 18 by the voltage control circuit 20 is increased, and the sound of the buzzer 19 is raised further.

If the alarm stop hole 6 inserted next is also other than the #1 alarm stop hole 6, the switch piece 5 is inserted through the stop switch 61 of the alarm stop hole 6 into which the switch piece 5 is inserted in the same way as described above. "H" output is generated, and this "H"
The output is given to counter 16 via OR gate OR1. As a result, the counter 16 counts up, and this count value is given to the decoder 23. Then, when the output of the decoder 23 is given to the voltage control circuit 20, the voltage control circuit 20
The level of the voltage V supplied to the buzzer drive circuit 18 is further increased, and the sound of the buzzer 19 is further increased.

Thereafter, in the same manner, if the sound stop hole 6 into which the switch piece 5 is inserted is not other than the target sound stop hole 6, the counter 16 is incremented each time, and the voltage control circuit 20 outputs a buzzer. The level of the voltage V supplied to the drive circuit 18 is further increased, and the sound of the buzzer 19 becomes even louder.

After that, when the switch piece 5 is inserted into the target sound stop hole 6 of #1, the "H" output is output via the corresponding stop switch 61.
Applied to the other terminal of AND11, the same AND gate
The "H" output of the AND11 is applied to the R terminal of the flip-flop 17 via the OR gate OR2, and the output of the Q terminal of the flip-flop 17 becomes "L" and the sound output by the fuser 19 is stopped.

Therefore, if you do this, to stop the buzzer while the alarm is being generated, pull out the switch piece inserted into the alarm set hole and insert it into one of the multiple alarm stop holes. Since it is necessary to find and insert a sound stop hole whose operation effectiveness is set in advance, the operation for stopping the sound becomes quite difficult. As a result, those who are woken up by the warning sound are required to operate the device while fully awake, and an effective wake-up effect can be expected. Furthermore, the volume of the buzzer increases each time the user fails to find the alarm stop hole, so the effectiveness of the alarm can be further enhanced.

Note that this invention is not limited to the above-mentioned embodiments, and can be implemented with appropriate modifications within the scope of the invention. For example, in the above-described embodiment, there is one alarm stop hole 6 for stopping the alarm sound by inserting the switch piece 5, but it may be provided at two or more locations.

[Effects of the invention] According to this invention, since the alarm stop operation is made difficult, it is possible to provide an electronic clock equipped with an alarm function that can be expected to have an effective wake-up effect.
