Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic timepiece with an alarm that allows modulation (frequency modulation, tone color modulation, rhythm modulation) of the same alarm sound.

Electronic clocks with alarms, especially watches, have been commercialized and sold as products over the past two to three years.

If they become more widespread in the future, it is conceivable that, for example, many people in one workplace may have electronic watches with alarms. Even if you don't go that far, it is expected that when you get on the train, several people will have one in the same car. In that case, the sound of the alarm alarm sound differs depending on the watch manufacturer, so if you both own watches from other manufacturers, you may be wondering if your own watch is ringing due to that sound. However, if two or more people happen to be holding watches made by the same manufacturer, they may be confused for a moment as they cannot tell whether their watch beeps or someone else's.

In addition, even if it is not a watch, the user's preferences,
If the alarm sound can be modulated and set depending on the situation when setting the alarm, the watch will be easier to use.

There are ways to make sounds different, such as changing the frequency to produce higher or lower sounds, changing the timbre, etc.
There are ways to change the rhythm.

Therefore, in consideration of these points, the present invention provides an electronic clock with an alarm, which includes a selection control circuit, an input terminal for transmitting a signal to the selection control circuit, a generated sound control circuit, and an alarm sound generation device. The circuit generates a plurality of modulated alarm sound signals corresponding to the signal from the selection control circuit, and transmits one signal from the plurality of modulated alarm sound signals to the alarm sound generator to generate the same alarm. By providing an electronic watch with an alarm that is configured to be able to notify with a modulated sound, even electronic watches with alarms made by the same manufacturer can be alarmed with different alarm sounds depending on the watch. The purpose is to inform and solve the problems mentioned above.

This will be explained below with reference to the drawings.

The figure is a circuit block diagram showing one embodiment of an electronic timepiece with an alarm according to the present invention, in which 2 is a reference signal generation source, 4 is a frequency dividing circuit, 6 is a timing circuit, 8 is a switching gate, 10 is a decoder circuit, and 12 is a drive circuit. circuit,
14 is a display device, 16 is an alarm time setting storage circuit, 18 is a coincidence detection circuit, 20 is an alarm coincidence storage circuit, 22 is a sound generation control circuit, 24 is an alarm sound generation device, 26 and 28 are operation switches, and 26 is a It can be operated independently and works as a display changeover switch.
8 works as an alarm sounding switch when operated alone, and works as an alarm sound selection switch when both are operated simultaneously. 30 is a switch circuit, and 32 is a selection control circuit.

When the held time of the clock circuit 6 reaches the time set in the alarm time setting memory circuit 16, it is detected by the coincidence detection circuit 18, and the output line 38 of the flip-flop 36 of the coincidence memory circuit 20 changes from L to H and is fixed.

At this time, the OR gate 40 of the generated sound control circuit 22
The output line 41 becomes H. On the other hand, and gate 4
2, 44, 46, 48, 50 are selection control circuits 3;
One of these output lines a, b, c, d, and e is always at H level, and when output line 41 is at H level, AND gates 42, 44, 46, 4 inputting output lines a, b, c, d, e at H level
8,50 one opens. For example, when the output line a is at H level, the AND gate 42 opens, and a signal with a frequency of ₁ is transmitted from the frequency dividing circuit 4 to the alarm sound generation circuit 54 via the OR gate 52, where it is created into an intermittent sound signal, and an alarm sound is generated. A generator 24 generates this intermittent tone. In this case, when the output lines b, c, and de of the selection control circuit 32 are at H, signals of frequencies ₂ , ₃ , ₄ , and ₅ are transmitted correspondingly, and the alarm is notified with sounds of different pitches. are doing.

If the user wants to change the height of this alarm sound,
Close both operating switches 26 and 28 at the same time.

At that time, the output line 58 of the AND gate 56 of the switch circuit 30 becomes H, the output line 62 of the flip-flop 60 becomes H, and the selection control circuit 3
This signal is transmitted to the shift register 66 via the OR gate 64 of 2 and shifts the contents of the shift register 66 by one. On the other hand, when the line 62 becomes H, the line 41 becomes H via the OR gate 40, regardless of whether the output line 38 of the coincidence storage circuit 20 is H or not. The alarm is starting to sound. That is, the operation switches 26 and 28 are simultaneously opened and closed, the shift register 32 is changed, and the output states of the output lines a, b, c, d, and e are changed, and after the opening and closing operation, both operation switches 26 and 28 are
If you keep it closed, you will hear an audible alarm with a signal at the selected frequency. Therefore, if the user selects an appropriate sound while checking the sounds, the alarm will sound at the selected pitch from then on.

Because of this structure, when purchasing a watch, the user must first select and set an appropriate alarm sound, and even if the watch is the same, if the selected sound is different, the alarm sound of the watch will be different from the alarm sound of the user. You will be able to distinguish between the alarm sounds of other people's watches.

Although the figure shows an example in which five types of pitches can be selected, more types may be added. Furthermore, in addition to modulating the pitch of the sound, it is also possible to perform timbre and rhythm modulation to vary the timbre or rhythm. In this case, the configuration is slightly different from that shown in the figure, and the configuration is such that the alarm sound generation circuit is controlled by the selection control circuit.

Further, instead of modulating only the pitch of the sound, it is also possible to select a sound with each of the pitch, timbre, and rhythm modulated.

With this configuration, the alarm sound can be selected in advance depending on the purpose and location.

As described above, the electronic watch with an alarm according to the present invention allows the user to select the alarm sound according to his/her preference, is distinguishable from the alarm sound of another person's watch, and also changes the alarm sound depending on the location and purpose. It is possible and the effect is great.

In the embodiment of the present invention, there is one alarm setting time storage circuit, but the present invention can be applied even if there is a plurality of alarm setting time storage circuits.

Additionally, the user was able to select the sound by operating the operating switch, but the external operating switch did not allow the user to select the sound and only provided an input terminal to transmit a signal to the selection control circuit. The person selects the sound before putting it in the outer case,
Each watch may have a different sound, and the user may select a watch with a preferable sound at the time of purchase.
