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 others heard them, they were jarring and a nuisance. As a result, there were many cases where someone else stopped the message and the message could not be conveyed to the person to whom it was intended, causing important promises and requirements to become obsolete.

The present invention ensures that a message is notified when someone is present, and also that the message is reliably conveyed to the person in question.

[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. If the device is played and left as it is, an alarm sound is generated again after a predetermined time, and a manual switch is provided to prohibit this operation, and the above operation is repeated unless the switch is operated.

[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). 7 is a voice synthesis circuit, 8 is a speaker, and 9 is an alarm circuit that generates an alarm signal. Reference numeral 10 indicates a counter for automatically stopping the alarm sound, and reference numeral 11 indicates a counter for automatically repeating the alarm. A human body sensor 12 detects the presence of a human body within a certain range. 13,14
is a flip-flop circuit, 15 is a delay circuit, and 16 is a flip-flop circuit.
~18 is a gate circuit, 19 is a one-shot circuit,
Reference numeral 20 is a ring stop switch that is operated when the message is understood.

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 output Q of the flip-flop circuit 13 is inverted to "1" and "0", respectively. The output Q generates one pulse from the one-shot circuit 19, the output Q of the flip-flop circuit 14 is inverted to "1" and "0", respectively, a signal is generated from the alarm circuit 9, and an alarm sound is emitted from the speaker 8. occurs. On the other hand, the reset of the counters 10 and 11 is canceled, the counter 11 measures the auto-repeat time of the alarm, and the counter 10 counts the ringing time for the auto-stop of the alarm sound. Also, flip-flop circuit 1
Power is supplied to the human body sensor 12 by the output Q of No. 3. 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 7 is triggered via the gate circuit 18. As a result, the audio information in the storage circuit 6 is read out and reproduced through the speaker 8. on the other hand,
The output from the human body sensor 12 is slightly delayed by the delay circuit 15, and then passes through the gate circuit 17, where the flip-flop circuit 14 is reset and the alarm sound is stopped.

In the above state, if the person detected by the human body sensor 12 is someone other than the person to whom the message is to be transmitted, the switch 20 is not operated. Therefore, the counter 11 continues to measure time, and when a predetermined period of time, for example 5 minutes, has elapsed, an output is generated and the flip-flop circuit 14 is triggered again. Therefore, the alarm sound is generated again, and the person to whom the message is to be conveyed is informed that the message has not yet been conveyed. When the person in question comes, the person is detected by the human body sensor 12 and a message is notified in the same manner as above. Once the message is conveyed to the person in question, the switch 20 is closed indicating that the message has been understood.

As a result, the flip-flop circuits 13 and 14
is reset, counters 11 and 10 are reset and return to their initial states, and the alarm sound is no longer generated.

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, the counter 10 generates an output after a certain period of time, for example, one minute after the alarm sound is generated, the flip-flop circuit 14 is reset, and the alarm sound is automatically turned off. Stop. However, since the flip-flop circuit 13 is not reset, the flip-flop circuit 14 is triggered after a predetermined time by the counter 11, and the alarm sound is generated again.

[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, unless the person in question consents and operates the manual switch, the alarm sound will automatically be generated again, so the message can be reliably conveyed to the person in question.

Therefore, it is possible to eliminate the inconvenience of missing important messages and forgetting important requirements.
