Abstract

PURPOSE:To enable execution of alarming and time signalling function at the same time by signalling time by the number of time of generating alarming sound. CONSTITUTION:When coincidence output is impressed from a coincidence circuit 4 by arrival of alarming time, a signalling circuit 6 selects frequency dividing output of a frequency divider 2 according to time counting of a counter 3. By this way, alarming sound including warning sound, time sound according to the number of time of generation, break sound etc. are generated. Thus, alarming function and time signalling function can be executed at the same time.

Description

[Detailed description of the invention] The present invention relates to an alarm clock.

Conventional alarm clocks simply generate an alarm sound to wake you up, so you have to pick up the clock to check the time. Especially in the middle of the night, you need to turn on the light and check the time.

Therefore, the present invention is designed to simultaneously perform an alarm function and a time reporting function by notifying the hour and minute of the alarm time by the number of times the sound is generated.

An embodiment of the present invention will be described below based on the drawings. 1st
In the figure, the output of crystal oscillator 1 is divided by frequency divider 2,
The current time is measured by a counter 3 and displayed on a display device 5 via a decoder 4. On the other hand, the output of the counter 3 is supplied to a matching circuit 4, and matched with the output of the alarm time recognition circuit 5. When the two match, the following output is generated from the notification circuit 6, and the alarm time is announced.

For example, if the alarm time is 4:23, a warning sound is first generated to wake the user from sleep as shown in FIG. Then, the time signal sound is generated four times to notify 4 o'clock, followed by a separator sound (it is preferable to make a sound different from the time signal sound).
occurs. After that, the 10-minute time signal was heard twice, and 20 minutes passed.
The time signal for one minute is emitted three times after the pre-separation signal is generated to notify the third minute. The above operation is repeated until the ringing is stopped. In this way, an alarm clock can fulfill its original function of waking you up from sleep, as well as a time signal function, freeing you from the hassle of turning on a light to check the time.

Note that it is preferable that the time signal sound can be more clearly identified by not only having a different pitch from the time signal sound, but also by reducing the volume.

Further, each of the above-mentioned sounds is not limited to a single sound, but a melody sound or the like may be used.

As described above, according to the present invention, it is possible to know the time while sleeping, and there is no need to turn on a light and check the alarm time as in the past. Moreover, since each digit of the time is indicated by a sound generation circuit, the circuit configuration is simple and costs can be kept low.
