Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an audio notification clock.

[Prior Art] Conventionally, there is a clock that includes a built-in tape recorder that records a message, and reproduces the message to notify the user when an alarm switch is closed.

[Problems to be Solved by the Invention] In the above system, when the alarm switch is closed at the set time, a message is automatically played even if no one is nearby, and the message is repeatedly broadcast until the alarm switch is stopped. This resulted in a large amount of wasted current consumption. Also, because he kept saying messages, when he got involved with others, he was annoying and annoying.

Therefore, it is conceivable to automatically stop the notification after a certain period of time, but in this case, the person in question may miss the notification, and there is a risk that important promises and requirements will become obsolete.

The present invention is designed to ensure that a message is sent when someone is present, and to notify that fact if the message cannot be delivered.

[Means for Solving the Problems] The present invention generates an alarm sound at the alarm time, and when there is a person nearby while the alarm sound is being generated, the audio information in the memory circuit is read by the output of the human body sensor. The audio information is reproduced, and if the audio information is not reproduced, a notification to that effect is provided.

[Example] In the drawings, 1 is a clock circuit that measures time;
Reference numeral 2 represents an alarm time setting circuit for storing the alarm time, and reference numeral 3 represents a comparison circuit for matching the current time with the alarm time. 4 is a time display section, and 5 is an input means for adjusting the current time and alarm time. Reference numeral 6 denotes a memory circuit made of a semiconductor, in which voice information to be emitted at a desired time is recorded. It is preferable that this audio information be rewritable so that the user can record any audio using a recording device (not shown). Reference numeral 7 denotes a memory circuit made of a semiconductor, which stores voice information to notify when the voice information in the memory circuit 6 has not been transmitted, such as voice information such as ``There is a message that has not been conveyed yet.'' 8 is a speech synthesis circuit, 9
1 is a speaker, and 10 is an alarm circuit that generates an alarm signal. Reference numeral 11 is a counter for automatically stopping the alarm sound, and reference numeral 12 is a human body sensor that detects the presence of a human body within a certain range. 13,1
4 is a flip-flop circuit, 15 is a delay circuit, 1
Reference numerals 6 to 18 are gate circuits, and 19 is a switch for manually reproducing the audio information in the memory circuit 6.

Next, the operation will be explained. When the current time coincides with the alarm time, an output is generated from the comparison circuit 3 and the flip-flop circuit 13 is set. The flip-flop circuit 14 is further set by the output Q, an alarm signal is generated from the alarm circuit 10, and an alarm sound is generated from the speaker 9. On the other hand, the reset of the counter 11 is canceled and the duration of the alarm sound is counted.
Further, power is supplied to the human body sensor 12 by the output Q of the flip-flop circuit 13. When a person hears the alarm sound and comes nearby, an output is generated from the human body sensor 12 and the voice synthesis circuit 8 is triggered via the gate circuit 17. As a result, the audio information in the storage circuit 6 is read out and reproduced through the speaker 9. On the other hand, the output from the gate circuit 19 is slightly delayed by the delay circuit 15 and then passes through the gate circuit 16, where the flip-flop circuit 14 is reset and the alarm sound is stopped.

When the reading of the audio information is completed, an output is generated from the terminal a of the audio synthesis circuit 8, and the flip-flop circuit 13 is reset to return to its initial state.

Note that the two inputs of the gate circuit 18 are set to "1" by the above-mentioned reset of the flip-flop circuit 14, but when a human body is detected, the output from the human body sensor 12 is a pulse with a width shorter than the delay time of the delay circuit 15. Therefore, when the flip-flop circuit 14 is reset, the output from the human body sensor 12 has already disappeared, and at this time, no output is generated from the gate circuit 18.

As mentioned above, since audio information is played back when someone is nearby, information can be reliably conveyed.

Next, a case where there is no one nearby at the alarm time will be explained. In this case, since the alarm sound is not stopped, an output is generated from the counter 11 after a certain period of time after the alarm sound is generated, the flip-flop circuit 14 is reset, and the alarm sound is automatically stopped.

After that, when a person approaches the vicinity of this timepiece device, an output is generated from the human body sensor 12, and the gate circuit 18
Output is generated from. As a result, the audio information in the memory circuit 7 is read out, and the speaker 9 emits the information "There is a message that has not been communicated yet." By pressing the switch 19, the audio information in the memory circuit 6 is read out and reproduced by the speaker 9. Upon completion of reading out the audio information, an output is generated from terminal a of the audio synthesis circuit 8, and the flip-flop circuit 13 is reset to return to its initial state.

In this way, if you are not near the clock device at the alarm time and cannot hear the audio information, you can check it later when you come near the clock device. In this case, in the above embodiment, the audio information in the memory circuit 6 is played back by pressing the switch 19, but the present invention is not limited to this. It may also be possible to play the data manually. In this case, the voice information in the storage circuit 7 may be, for example, a message such as "We were unable to deliver your message at the set time, so we will notify you now."

Further, in the above embodiment, the fact that the audio information could not be conveyed at the alarm time is notified by voice, but the notification is not limited to this, and the notification may be made by some kind of display. For example, a light emitting diode may be turned on or blinked.

[Effects of the Invention] According to the present invention, when an output is generated from a human body sensor while an alarm sound is being generated, audio information in the memory circuit is played back, so a message can be notified when no one is present. This inconvenience can be resolved, wasteful current consumption can be suppressed, and it is no longer a nuisance to others.

Furthermore, by notifying the user when audio information is not reported, it is possible to eliminate the inconvenience of missing an important message and forgetting important requirements. In this case, especially if the human body sensor is used to detect and notify the presence of a person, the notification can be reliably notified.
