Description

[Detailed Description of the Invention] The present invention relates to an alarm clock that generates a setting confirmation sound when setting an alarm operation.

Figure 1 shows a schematic configuration diagram of an alarm clock using a conventional voice synthesis IC. 1 is an alarm switch, which is turned on only once every 12 or 24 hours for 30 minutes to 1 hour. It is a mechanical switch that Further, 2 is a set switch, one end of which is connected to the alarm switch 1, and the other end to which a power supply voltage Vcc is applied. However, if the set switch 2 is turned on at bedtime, when the set time comes and the alarm switch 1 is closed, the voice synthesis IC 3 will work and the alarm sound will be generated from the speaker 4. When the set switch 2 is opened, the alarm sound is stopped. By the way, the output of the set switch 2 is converted into a one-pulse output via the differentiating circuit 5, and the sound for confirming the set is generated only once at the moment the set switch 2 is closed. Therefore, if the alarm switch 1 was already closed when the set switch 2 was closed, there was a problem in that it was impossible to tell whether the set confirmation sound or the alarm sound would be output. Of course, in normal use, the set switch 2 is pressed when sleeping, and the alarm switch 1 is closed when waking up, so when the set switch 1 is closed, the alarm switch 1 should be open. When a person receives an explanation of the operation of a watch at a store, he or she may try out various ways of using the watch, such as closing the set switch 2 while the alarm switch 1 is closed. In such a case, it is originally desirable that the set confirmation sound is output only once and then the alarm sound is output continuously the moment the set switch 2 is closed. In the conventional example shown in the figure, there was a problem in that if the set switch 2 was closed while the alarm switch 1 was closed, it was uncertain whether or not a sound for confirming the set would be output.

The present invention has been made to solve these problems of the conventional example, and provides an alarm clock that always makes a setting confirmation sound when the set switch is closed with the alarm switch closed. The purpose is to

The configuration of the present invention will be described below with reference to illustrated embodiments. FIG. 2 is a block diagram showing a schematic configuration of an embodiment of the present invention. 1 is an alarm switch consisting of a mechanical contact that is turned on when the current time of the alarm clock body A matches the alarm setting time;
2 is a set switch for selecting whether or not to perform an alarm operation. Delay circuits 6 and 7 prevent the switches 1 and 2 from chattering. The delay time of the delay circuit 6 connected to the alarm switch 1 side is longer than the delay time of the delay circuit 7 connected to the set switch 2 via the differentiating circuit 5. Therefore, when the set switch 2 is closed while the alarm switch 1 is closed, an output is first generated from the delay circuit 7 side, and then an output is generated from the delay circuit 6 side. 3 is a speech synthesis IC that divides the speech signal into minute sections that can be considered as almost constant repetitions of the same waveform, and converts data obtained by pulse code modulating the basic waveform, which is the minimum unit of repetition within these minute sections, into phoneme pieces. The data ROM 8 stores a plurality of basic waveforms, and the voice message ROM 9 stores information on how many times to repeat which basic waveform among the plurality of basic waveforms stored in the phoneme piece data ROM 8. The address table contains the start addresses of voice messages.
This is stored in the ROM10. 11 is an oscillation circuit, and 12 is a timing control circuit. The digital signal output from the phoneme piece data ROM 8 is converted into an analog signal by the D/A converter 13, then amplified by the power amplifier circuit 14, and output from the speaker 4 as a voice message. However, when the set switch 2 is closed, the voice synthesis IC 3 outputs "Good night." as the voice for setting confirmation, and when the alarm switch 1 is closed, the voice for the alarm is "Good morning!" ” is now output. Therefore, if you close the set switch 2 with the alarm switch 1 open when you go to bed, the sound for confirming the set will be generated only once in response to the output of one pulse generated by the differentiating circuit 5. When the current time becomes equal to the alarm setting time, the alarm switch 1 is closed and the alarm sound is repeatedly output. This alarm sound stops when the alarm switch 1 is opened, but can be forcibly stopped by turning off the set switch 2. Furthermore, if the set switch 2 is closed while the alarm switch 1 is closed, the delay circuits 6 and 7 start at the same time, so the delay circuit 7 with the shorter delay time generates the output first, and the sound for confirming the set is output first. is output to
Subsequently, an alarm sound is repeatedly output.

In the description of this embodiment, an example is shown in which a voice message is used as the set confirmation sound and alarm sound, but it is also possible to use a music box sound or a buzzer sound instead.

The present invention is configured as described above, and includes a watch body that measures and displays the current time, an alarm switch that turns on when the current time and the alarm setting time match, and a selection for whether or not to perform an alarm operation. one end of the alarm switch and the set switch are connected to each other, the other end of the set switch is connected to a power supply, the other end of the alarm switch is connected to an alarm sound generating means via a delay circuit, and Since one end is connected to the set confirmation sound generation means via a differential circuit, when the set switch is closed while the alarm switch is closed, the set confirmation sound generation means operates first, and then the alarm is generated. Since the sound generating means operates, the setting confirmation sound is always generated, and even if the purchaser tries various usage modes when receiving an explanation of the operation of the watch at the store, the setting confirmation sound will always be generated when the set switch is closed. This has the effect of generating.
