Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to an alarm clock that controls the volume of an alarm based on the alarm sounding time, and sometimes based on the average value of past alarm sounding times. This relates to a device that increases the alarm volume in accordance with the number of snoozes when the alarm sounding time becomes longer than this.

(b) Prior Art A conventional alarm clock of this type is disclosed in Japanese Patent Publication No. 62-4674.
In this alarm clock, if the alarm continues to ring for a certain period of time, it is determined that the alarm volume at that point will not wake the user.
The alarm volume will be increased at the next alarm notification.

In addition, as a device that changes the alarm volume depending on the alarm sounding time, there is
There is a clock described in Publication No. 145478.

This watch determines the depth of sleep based on the time from the generation of the alarm sound until the snooze operation is performed, and suppresses the alarm volume after the snooze.

(c) Problems to be solved by the invention In general, there is not necessarily a relationship between the current situation and the situation at the time of the next alarm notification.
Even if the same user uses it, since it is difficult to wake up now, there is no guarantee that it will be the same next time.

Therefore, in the former conventional example, the volume may be excessive because the previous alarm sounded for a long time even though the user wakes up early, or the previous alarm sounds for a short time even though the user does not wake up easily. The volume of the alarm may be too high or too low, such as the volume being insufficient due to the alarm volume, which is not efficient.

In addition, in the latter conventional example, it is necessary to set a standard for determining the length of the alarm sounding time in advance, but it is not possible to establish this standard value for each user, and it is necessary to set an appropriate judgment standard. could not be determined.

An object of the present invention is to provide an efficient alarm clock that does not have too much or too little volume by setting appropriate judgment criteria for each person and controlling the volume of the currently operating alarm based on this criteria. That's true.

(d) Means for Solving the Problems In order to solve the above problems and achieve the purpose, the alarm clock of the present invention includes a clock section, an alarm circuit, a ring stop switch, a snooze switch,
In a watch with a snooze circuit, the output of the alarm operation signal from the alarm circuit due to the operation of the sound stop switch is stopped to the Nth power of 2 (N=1, 2, 3).
…) An operation counting circuit that outputs a carry signal every time it counts, a pulse generation circuit that outputs N shift pulse signals in response to this carry signal, and A cumulative clock circuit that measures the time until the switch or snooze switch is operated, and a cumulative clock signal that presets the cumulative clock signal from the cumulative clock circuit in response to the output of the carry signal and a cumulative clock signal in response to the output of the shift pulse signal. a shift circuit that shifts N bits to the lower level; an individual timer circuit that is initialized each time an alarm operation signal is output and measures the time from when the alarm operation signal is output until the mute switch or snooze switch is operated; Comparison circuit that compares with the individual time signal and outputs an excess signal when the individual time signal is large, outputs a predetermined volume designation signal when the excess signal is not output, and outputs a volume designation signal corresponding to the number of snooze switch operations when output The present invention is characterized in that it is provided with a volume designating circuit that responds to an alarm operation signal and a notification circuit that notifies an alarm sound having a volume corresponding to the volume designation signal in response to an alarm operation signal.

(e) Effect In the alarm watch of the present invention, the number of times the output of the alarm operation signal is stopped is counted in the operation counter circuit, and the counted value is set to the N power of 2, for example, N=2 to be "4". When this happens, a carry signal is output.

The pulse generation circuit outputs N (two) shift pulses in response to the output of this carry signal.

On the other hand, the cumulative timer circuit counts the time during which the alarm operation signal is output, and accumulates the counted value until a certain period of time elapses after the carry signal is output from the operation counter circuit.

That is, the alarm sounding time during 2 N times (4 times) of alarm notification is accumulated and counted.

At this time, the shift circuit receives the N times (4 times) accumulated in the cumulative clock circuit in response to the carry signal.
The alarm ringing time is preset.

Then, N (2
In response to N(2) shift pulses, the preset value is shifted N(2) bits downward.

As a result, the preset alarm sounding time for 2 to the N power (4 times) is divided by 2 to the N power (4), and the average value of the alarm sounding time is set.

Further, the individual timer circuit counts the current alarm sounding time and supplies an individual timer signal indicating the counted value to the comparison circuit.

This comparator circuit compares the past 2 N from the shift circuit.
The shift signal indicating the average value of the alarm ringing time for each ride is compared with this individual timing signal, and if the ringing time indicated by the individual timing signal is longer than the average value,
Outputs an excess signal.

The volume designation circuit outputs a predetermined volume designation signal when this excess signal is not output.

Further, when the excess signal is being output, the volume designation circuit is in a state of outputting a volume designation signal corresponding to the number of times the snooze switch is operated.

Therefore, if the alarm sounding time becomes longer than the average value, the alarm sound will be increased according to the number of snoozes.

Reference numeral 80 denotes a notification circuit, which includes a notification signal generation circuit 82 which inputs an alarm operation signal from the alarm circuit 18 and outputs a notification signal, and inputs the notification signal and a volume designation signal from a volume designation circuit 88 to designate the volume. It is comprised of a drive circuit 84 that outputs a drive signal according to the signal, and a speaker 86 that emits an alarm sound when the drive signal is input.

Next, the operation of the alarm clock having the above configuration will be explained.

First, when the alarm time comes and a signal is output from the reference mechanism 16, a pulse is output from the OS 24 in the alarm circuit 18 that receives the signal.

FF26 inputs this pulse to set input S.
is set, and the signal from its output Q goes to H level.

When the signal from this FF26 becomes H level,
Since the output signal of the snooze timer 30 in the snooze circuit 19 is also normally at H level, the AND gate 3
An H level signal is generated in the alarm operation signal outputted by No. 2.

When this alarm operation signal becomes H level, the notification signal generation circuit 82 in the notification circuit 80 outputs a notification signal in response, and the drive circuit 84 applies a drive signal to the speaker 86 in response to this notification signal. to generate an alarm sound.

If the alarm notification at this time is the fourth alarm notification after battery insertion, the cumulative clock circuit 50
This means that the counter 56 within has not yet made the necessary counts to find the average value of the four times.

Therefore, in this case, the shift register 70 in the shift circuit 62 applies the predetermined value output by the preset encoder 66 when the initial reset circuit 64 outputs the signal to the comparator circuit 78 as a shift signal. There is.

Note that the value indicating the time preset in the shift register 70 is 5 seconds, 10 seconds, etc.

On the other hand, the counter 76 in the individual timekeeping circuit 72 applying the individual timekeeping signal to the comparison circuit 78 is
OS74 in response to the H level alarm operation signal.
The AND gate 60 is initialized by the pulse output from the AND gate 60 and remains open only during alarm operation.
The clock signal φ ₁ generated at the output of is inputted to the clock input φ to count the alarm sounding time.

In this way, the comparison circuit 78 inputting the individual clock signal indicating the alarm sounding time and the shift signal indicating the predetermined time compares these signals, and if the alarm sounding time is longer than the predetermined time, The output excess signal is switched, for example, from L level to H level.

When the excess signal reaches the H level in this manner, the gate circuit 94 in the volume designation circuit 88 outputs a predetermined volume designation signal when the excess signal is at the L level. The state is set to output the specified signal.

Therefore, the snooze switch 22 is operated here, the output signal of the AND gate 28 becomes H level, and the counter 9 is activated in synchronization with the rise of this signal.
2 advances the count, the gate circuit 94 outputs a volume designation signal according to the count value.

Then, the drive circuit 84 increases the volume of the drive signal in response to this volume designation signal, thereby increasing the alarm sound.

Incidentally, the count value of this counter 92 is determined by the FF in the alarm circuit 18 when the ring stop switch 20 is operated.
When 26 is reset, it is reset by the output signal of inverter 90 which inverts its output signal.

In this way, using a predetermined value as a reference value, comparing whether the alarm duration has become longer than this value is done after the battery is inserted until the necessary data is collected to determine the appropriate reference value. This is only the case when the alarm is activated up to the fourth time.

The cumulative timing circuit 50 accumulates the data necessary to determine such an appropriate reference value, that is, the time from the start of the alarm operation to the first operation of the snooze switch or the first operation of the silence switch. I am counting.

Specifically, when a pulse is output from the OS 24 in the alarm circuit 18 at the start of the alarm operation, the FF 52 is set by this pulse.

Therefore, the signal from the output Q becomes H level, and the AND gate 54 becomes open.

Therefore, the output of the AND gate 54 contains the clock signal φ ₁ generated at the output of the AND gate 60.
occurs.

Counter 56 counts the clock signal φ ₁ generated at the output of AND gate 54 .

When the snooze switch 22 or the sound stop switch 20 is operated and the alarm operation signal goes to L level, the FF 52 inverts this signal and inputs it to the clock input φ. signal to L level.

Therefore, the AND gate 54 is closed,
Counter 56 also stops.

The data input D of this FF52 is grounded,
Since it is always at the L level, the output Q will not go to the H level until a pulse is output from the OS24 again, and even if the snooze operation is performed several times, the first It is configured so that the output Q is set to H level only until the snooze switch is operated, and the alarm sounding time is counted.

This is because the increase in the volume of the alarm sound is necessary to wake the user up, not to wake the user up, so the increase in the volume of the alarm sound is determined by the amount of time it takes to wake up from a sleeping state, that is, from when the alarm starts sounding to when the sound stop switch 20 This is because a more appropriate reference value can be obtained by counting the time until the user operates the snooze switch 22 or the time until the first operation of the snooze switch 22.

If the ring stop switch 20 is operated now, an H level operation signal is applied to the reset input R of the FF 26 in the alarm circuit 18, thereby resetting the FF 26.

Therefore, the signal from the output Q of the FF 26 becomes L level, the AND gates 28 and 32 are closed, and the alarm operation signal becomes L level.

At this time, the counter 38 in the operation counting circuit 34, which inputs the signal from the output Q of the FF 26 to the clock input φ via the inverter 36, advances the count in synchronization with the rising edge of the input signal.

When the snooze switch 22 is operated, an H level signal is applied to the snooze timer 30 via the open AND gate 28, and in response, the snooze timer 30 changes the output signal for a certain period of time to an L level and then The gate 32 is closed.

However, since the output signal of the FF 26 remains at the H level at this time, the counter 38 in the operation counting circuit 34 does not advance the count no matter how many times the snooze operation is repeated.
Here, if this counter 38 counts "4" and generates a pulse in the carry signal from its output C, this pulse is applied to the shift circuit 62, the pulse generation circuit 40, and the cumulative time measurement circuit 50. .

The shift register 70 in the shift circuit 62 inputs the pulse generated in the carry signal via the OR gate 68 to the preset input PE, and presets the four alarm ringing times accumulated in the counter 56 in the cumulative timer circuit 50. do.

Note that this counter 56 is subsequently reset by a pulse generated in the carry signal delayed by the delay circuit 58.

Further, the pulse of the carry signal applied to the pulse generating circuit 40 is delayed for a certain period of time by a delay circuit 42 to ensure operation, and then applied to the set input S of the FF 44 to set it.

Therefore, the signal from the output Q becomes H level, the AND gate 46 is opened, and the clock signal φ ₂ is generated as the output.

Counter 4 has been reset since the signal from the output of FF44 has gone to L level.
8 counts the pulses generated at the output of the AND gate 46, and when the value reaches "2", outputs a pulse from the output C and resets the FF 44 and the counter 38. When the FF 44 is reset, the signal from its output Q goes to L level, which causes the AND gate 46 to close.

As a result, two pulses are generated in the shift pulse signal output by the AND gate 46. The two pulses generated in this shift pulse signal are applied to the clock input φ of the shift register 70 in which the accumulated alarm sounding time has been preset.

Then, this shift register 70 shifts the preset value by the number of input pulses "2" to the lower bits.

This will change the cumulative value of the 4 presets to 4
This means that the average value is set in the shift register 70.

Therefore, when the alarm operation is performed four times, the average value of the alarm sounding times is supplied to the comparator circuit 78 as a shift signal.

Therefore, in the subsequent alarm notification, the comparison circuit 78 uses this average value as a reference to detect the length of the active alarm sounding time indicated by the individual clock signal from the individual clock circuit 72.

When the excess signal is output from the comparison circuit 78, the gate circuit 94 in the volume designation circuit 88 outputs a predetermined volume designation signal until the excess signal is output, as described above. A volume designation signal is output in accordance with the count value of a counter 92 that counts the number of times the snooze switch 22 is operated.
Thereby, the drive circuit 84 increases the volume in accordance with this volume designation signal.

Thereafter, the above operation is repeated every four alarm operations, and the average value based on new data is always set in the shift register 70.

In this embodiment, the average value of four alarm operations is calculated, but the operation counting circuit 3
The count number of the counter 38 in 4 is arbitrarily determined as 2 to the N power, and the number of pulses generated in the shift pulse signal output by the pulse generation circuit 40 is determined as N.
By setting the number of times, the average value over an arbitrary number of times can be used as a reference.

(g) Effects of the Invention According to the present invention, the average value of the alarm ringing time of several times by the user is used as a standard, and appropriate judgment criteria are set for each user, and control is applied to the currently operating alarm. Since the alarm is carried out, the volume of the alarm is not excessive or insufficient, making it efficient.

Furthermore, since the amount of volume variation depends on the number of snoozes, even if you are in a deep sleep that you cannot wake up immediately even with the snooze function, you can definitely wake up.
