Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a fin clock that uses sound to accurately tell the time.

In the recent trend toward electronic watches, electronic watches are being considered that incorporate an electronic buzzer into the watch and tell the time using Morse code or the like. These watches are a great aid to people who are visually impaired, and are also of great value because they allow people to tell the time without using a time display panel in dark places or in situations where it is dangerous to look at the watch. It gives

The present invention is effective when correcting and setting the time using only the sound of an electronic clock that uses sound.

According to the present invention, it becomes easy for a visually impaired person to use an electronic watch that clocks with sound, and it also becomes possible to create an inexpensive electronic watch without a display panel.

The present invention will be described in detail below with reference to the drawings. Fig. 1 is a block diagram of an embodiment of an electronic timepiece that informs the time by sound.

A relatively high frequency signal from the oscillating section 1 is opaquely filtered by the frequency dividing section 2 to form information on each digit of time. The oscillation section i' is generally performed using crystal oscillation, which is stable and preferable, but is not limited to crystal oscillation. The selection section 3 is for selecting the time digit of the frequency dividing section 2, and is sequentially switched by the control section S to the hour digit, the tenth digit, and the one minute digit. The converter 4 forms a serial signal such as a Morse code from a parallel signal such as a binary or one-way signal sent from the selector 3.

The serial signal from the converter 4 is turned into a sound code by a sound generator 6 including an electronic buzzer, which can notify the time.

The control unit 6 includes a demand switch that commands the time alarm, a lock switch that specifies a modification prohibited state (locked state) and a modification possible state (unlocked state), a digit designation switch that designates the correct digit, and a digit designation switch that designates the correct digit. It has a correction switch for making corrections.

In order to know the time using the electronic timepiece of the present invention, by pressing the demand switch of the control section 6, the time is reported by the sounding section 5 each time, and the time can be known. Next, the time adjustment operation will be explained.

An operation in which the correction lock state is released by the lock switch of the control unit 6 to an unlocked state, the correction switch of the control unit 6 is pressed, and the information of the time digit corresponding to the correction switch is increased by one in the mirror that is pressed once. to set the correct time. To correct the Tazoshi seconds, it is appropriate to return to 0 current @ by pressing the correction switch. The control section 6 controls the sound generation section 5 to generate a warning sound in the unlocked state in order to reliably indicate to the user that the unlocked state is correctable.

Therefore, you can confirm that the adjustment is being made while you hear the warning sound, and you can also prevent malfunctions such as the switch being pressed and unlocked without your knowledge, causing the clock to go awry. Further, the control section 6 performs control so that the sound generation section 5 generates a different warning sound for each positive digit, as described below. The total number of switches can be reduced by using one switch for two purposes, such as having one switch function as a demaso switch in the locked state and as a correction switch in the unlocked state.
FIG. 2 explains the present invention in more detail, and shows a configuration in which the warning sound is changed for each corrected digit of the time.

7 is a correction digit designation circuit which is a part of the control unit 6 in FIG. Digit specification (M) → Time specification (H) → Lock status and lock/unlock or correction digits (S, M, H) are specified.

In the locked state, the AND gate 8 is open, and when the demand switch is pressed, the Morse signal 15 representing the time passes through the OR gate 12, and the AND gate 13 drives the buzzer 14 with an excitation signal 16 of about Hz to generate a signal. time.

When S of the correct digit designation circuit is selected by operating the lock and correction digit designation switch, the AND gate 11 outputs a 4Hz signal to the OR gate 12 indicating that seconds can be corrected with the rear correction switch, and today's Z cost is output. is intermittent at 4Hz, and the buzzer 14 issues an intermittent warning sound. With M selected, AND gate 10! From this, on 2HZ and 2HZ, the AND gate 9 is used to connect IHZ and ``In both cases, the buzzer is driven by a signal in which the excitation signal 16 is intermittent, and a warning blue signal with different intermittent cycles is emitted.This allows you to determine which digit of the time can be corrected. It can be clearly distinguished.Therefore, correction can be made even more easily by pressing the correct switch, which is different from the switch that operates the counter 7, the desired number of times.In this embodiment, the lock switch and the digit designation switch are By making it common, this lock, correction digit designation switch and correction switch 2
It is also possible to configure it with just one piece. In this embodiment, the period of the intermittent blue is changed in order to distinguish between the digits of the time that can be adjusted, but the period of the intermittent blue tone may be changed during the period during which the intermittent tone is emitted at a constant frequency.

We are also considering ways to change the pitch of the sound that can actually be heard by changing the frequency of the excitation signal, such as ``2 for S correction, 2 for Utahi, 1 for M correction, Kitsune HZ, and 1. HZ for Hibisei. As described above, according to the present invention, it is possible to notify the user by sound that the correctable unlocked state has been reached and the correctable digit, thereby preventing erroneous corrections and facilitating correction operations. can.
