[Industrial application field]

The present invention is a cordless (wireless) device configured so that the alarm sound can be heard only by you and not by others at a predetermined set time.
This invention relates to a time notification device. Therefore, incorporating this device (circuit) into NTT's pager is also an effective method of utilization.

[Prior Art] In recent years, a wide variety of alarm clocks have come on the market, such as those that sound a music box or chime when a preset time arrives, or that use a human voice to notify the user that the time has arrived. There is.

Additionally, some wristwatches have the ability to notify the time with sound. Recently, electronic notebooks with notification functions are increasingly being used to manage schedules such as company meeting times, salespeople's appointment times with customers, and lawyers' court appearances.

[Problems to be Solved by the Invention] By the way, conventional alarm clocks and electronic notebooks with alarm functions emit sound, which may disturb people in the same room or in the next room.

Additionally, a surprisingly large number of people tend to fall asleep as soon as they take their seats on the commuter train. These people know the approximate time it will take to commute to work, so setting an alarm clock to go off at that time can prevent them from falling asleep and missing the train.

However, if the alarm suddenly goes off inside the car, it will cause trouble to the passengers nearby. Therefore, it may be a good idea to use an alarm clock that sounds an alarm through earphones or headphones so as not to disturb others. However, if such devices are used, as can be inferred by looking at people who listen to portable tape recorders through headphones, they can be used to avoid bothering others, but the coat that connects to the earphones or headphones becomes a hindrance,
The problem is that it is extremely difficult to use.

In consideration of such problems, the present invention has been devised so that the set time is reached without causing inconvenience to others and without using any obstructions such as earphone cords that may get caught or become tangled. To provide a cordless time notification device in which an alarm can be heard only by the user.

This notification sound stimulates the eardrum, allowing the user to recognize that the scheduled time has arrived. At this time, the notification sound cannot be heard by others, so there is no need to bother others.
