Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a voice time world clock.

[Prior Art] A conventional audio timepiece reports only an alarm sound and an alarm time at an alarm time. Therefore, when used as a world clock, there is a problem that when the alarm sounds, it is not known which area the alarm is set to.

As a solution to the above problem, there is an electronic timepiece that issues an alarm sound with a melody that differs depending on the area, so that it is possible to know which area the alarm sound is by listening to the information sound. It is disclosed in the official gazette.

[Problems to be solved by the invention] In a conventional world clock that sounds an alarm sound with a different melody depending on the region, it is necessary to remember which melody corresponds to which region by yourself. It is annoying.

The present invention eliminates the above-mentioned conventional drawbacks and makes it possible to easily know in which area the alarm sound is set.

[Means for Solving the Problems] The present invention is provided with a voice storage circuit for storing the names of major cities in each country of the world, and is provided with a notifying circuit for notifying the city name of the area where the alarm is set with an alarm sound at the alarm time It was done like this.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 is a clock pulse generation circuit for generating clock pulses, 2 is a voice memory circuit in which the names of major cities in the world and words for informing the time are stored, and 3 is an alarm time and its alarm time. An alarm time setting circuit for setting a city name, 4 is a time measuring circuit for measuring the time of a reference city, and 5 is a signal supplied from the clock pulse generating circuit 1 to the time measuring circuit 4 and set in the alarm time setting circuit 3. The CPU (central control circuit) detects a match between the alarm time and the time stored in the clock circuit 4 and performs various controls when the two match. 6 is CP
A voice synthesizing circuit for selectively reading data from the voice storage circuit 2 based on a signal from U5 and outputting a voice signal, 7
Is a DA converter that converts a digital signal from the voice synthesis circuit 6 into an analog signal and outputs the analog signal. Timing circuit 4
The CPU 5, the voice synthesizing circuit 6, and the DA converter 7 constitute a notification circuit 8. 9 is an alarm sound generation circuit, 10 is a DA converter 7 and an alarm sound generation circuit 9
The amplifier circuit 11 amplifies the signal from the amplifier, and the sound generating device 11 generates a sound based on the signal from the amplifier circuit 10.

Next, the operation will be described. The clock circuit 4 clocks the time of the reference city, and the clock pulse generation circuits 1 to 1
The clock pulse generated every second advances the time every second.

When the alarm time and the city name are set in the alarm time setting circuit 3, the CPU 5 subtracts the time difference between the set time of the city and the reference time stored in the timing circuit 4 from the set alarm time. , And outputs a signal to the voice synthesizing circuit 6 and the alarm sound generating circuit 9 when they match with the reference time stored in the time counting circuit 4. The alarm sound generation circuit 9, when supplied with a signal from the CPU 5, outputs an alarm signal. On the other hand, when a signal is supplied from the CPU 5, the voice synthesizing circuit 6 selects and reads out the city name and time data from the voice storage circuit 2 based on the signal, and outputs a voice signal based on the data. The audio signal is converted into an analog signal by the DA converter 7 and output. For example, if 2:00 am in New York is set as the alarm time, "New York is 2:00 am" is notified.

With the configuration and operation as described above, it is possible to inform the city name of the area where the alarm is set together with the alarm sound and the alarm time.

[Advantage of Invention] According to the present invention, since the alarm time can be notified together with the city name of the set area, it is possible to easily and surely know in which area the alarm is set. It is a thing.
