Abstract

PURPOSE:To let a blind person know time through oscillation by providing oscillation parts for minute annunciation corresponding to specified unit intervals of >=5min and 12 oscillation parts for hour annunciation corresponding to respective hours, and oscillating them in accordance with the time. CONSTITUTION:Diaphragms each having a fixed piezoelectric oscillator are arranged for minute annunciation as shown by M1-M12 at intervals of 5 minu, and oscillation parts for hour annunciation are arranged as shown H1-H12 at intervals of one hour. When current time is selected with a switch ST, respective oscillation parts oscillate in accordance with the contents of a counter which counts the current time and the user feels the oscillation with a finger. At alarm time, the oscillation parts M1-M12 are all driven at an audio frequency to generate an alarm sound.

Description

[Detailed description of the invention] The present invention is intended for use in watches for the blind.

Conventional watches for the blind use pointer type watches, and are designed so that the current time can be determined by touching the pointer directly. As a result, when you touch it with your finger, the hands may move and the time may be off.
The pointer may become bent. Furthermore, when adjusting the time, the user must turn the leash while touching the pointer, which is cumbersome. Furthermore, there are drawbacks such as the difficulty of adding an alarm function or the like.

Therefore, the present invention uses a plurality of minute alarm vibrating sections provided corresponding to each predetermined single furnace minute of 5 minutes or more and a 12-hour hour alarm vibrating section to drive the vibrating section corresponding to the current time, To provide a watch for blind people that allows the user to know the time by touching the watch.

An embodiment of the present invention will be explained below based on the drawings. 1st
In the figure, BA and BT are respectively an alarm time and current time selection switch, a RLH lock switch, and a BH
, SM are wb and minute correction switches, and S-0 alarm silence switch, respectively. H1-H and Mt
~M+t are the vibrating parts for when and for minute notification when piezoelectric vibrators are used, respectively, and FIG. 2 shows an extracted part of the vibrating part Mst. In the figure, a piezoelectric vibrator MPo is fixed to a diaphragm having one end fixed.

A pin P11 is erected on the free end side of the diaphragm Lo, and its tip is placed in a hole drilled in the front plate of the watch. The other vibrating parts also have the same configuration as the upper P.

In Figure 3, Q is a crystal oscillator, p-gear divider,
The digit counter receives a 1-minute period signal from the branch circuit, and
produces output in minutes. Both MT and HT are counters that measure the 5-minute train-side time and the ridge. MA is a setting circuit for setting the fifth minute of the alarm time, and a setting circuit for setting the false alarm time for HA. BH is a selection circuit that selects either the current time or the alarm time. KM, KH respectively vibrating part M, ~Mt
t and H1 to HtX drive control circuits, and DM and DH are drive circuits. SV is a switching circuit for setting the clock and alarm time, and A is a control circuit for setting the temporary and alarm time, which includes a counter for setting the time.

Note that the switches HA, BT, BL, SJ in Figure 1
B.M.

The outputs from SO are terminals Fa and St in Figure 3, respectively.
.

81, Bh, Bm, BoK can be supplied.

Next, the operation will be explained. First, when it is desired to know the current time, the switch 8 is pressed to generate a selection output of the current time from the switching circuit SV. According to the second output, the outputs of the counters MT and HT are selected by the selection circuit PIljK. If the current time is 9:12, the output of the counter MT selects the vibrating section M, and the inaudible drive signal of 16 Hz or 32 H2 is transmitted twice by the output of the counter C. The drive circuit DMK is intermittently supplied. As a result, the vibrating part Mtf12
It is driven intermittently. On the other hand, the output of counter HT indicates that SAT! PFa(!iiJ! is supplied to the drive circuit DMK via the input force control circuit, and the vibrating section R is driven by the upper !li' drive signal.

Therefore, the user touches each hole with his or her finger, and
I learned that it was around 9 o'clock by the stimulation from the tip of the 0 pin, and the vibrating part M! It is possible to know that K is 12 minutes by the fact that the bins in KM are moving intermittently KM twice each time.

Since the minute vibrating section is provided in units of 5 minutes, it is possible to provide notification in units of 1 minute by intermittently vibrating the number of times corresponding to the minutes that are less than 5 minutes.

If the alarm time is to be known, the switch SA is pressed and the switching circuit SW produces an alarm time selection output, and the alarm time output of the counters MA and HA is selected by the output of the selection circuit SZ.

This output causes the vibrating section corresponding to the alarm time to vibrate, similar to the above P, and by touching this, the user can know the alarm time and smoke.

Next, if you want to adjust the current time, first press switch BT.
After pressing , pull out switch 8L. As a result of this, the control circuit A is in an operating state.Press the switch BH the desired number of times (the number of times corresponding to the desired setting).
The desired time is set in the hour digit of the counter within. Next, when the switch 8M is pressed a desired number of times, the desired minute is set in the minute digit of the counter in the control circuit A. By pressing the switch 8L, the setting time of the upper P counter is preset to the counters MT and HT, and the frequency division JaD and counter O are reset.

Note that it is generally preferable to set 1 hour according to Wp@ of the hour; in this case, it is only necessary to set the hour digit, and there is no need to operate switch SM.

To set the alarm time, pull out switch SL, press edge switch SA, and press switch E in the same way as above r.
By pressing IH and SM the desired number of times, the desired alarm time is set in the cursor in control circuit A, and the switch...
Setting circuits MA and HAK can be preset by pressing T.

When the current time coincides with the alarm time, an output is generated from the matching circuit Cy, and a drive signal is generated from the drive control circuit KM for the multiple vibrating parts M+ -Mlt, and these K generate an alarm sound of sufficient volume. do. The ringing is stopped by turning the switch SO to OFF.

Also, if the switch 80 is turned OFF, the hands, that is, the alarm, are not set, and no notification sound will be generated even if the alarm time is checked. In other words, the output of the switch SO and the switching circuit 8W
The drive signal from the drive control circuit KM is
It is prohibited to use the above-mentioned V-operation ridge. This is to avoid the possibility that if the alarm time is announced even though the alarm is not set, the user may mistakenly believe that the alarm is set.

The vibrating parts H1 to H1tIc generate an alarm sound, and the vibrating parts M1 to Mu and Hl-H1! It may also be possible to cause an alarm sound to be generated by all of the following.

In addition, in the above embodiment, a bottle is set up on the diaphragm and the fingertips are stimulated by this pin, but it is not always necessary to use this pin, and it is not necessary to touch the diaphragm directly from the hole. good.

In the above embodiment, the vibrating parts for minute notification are installed in units of 5 minutes, but are not limited to this, and for example, six units may be installed in units of 100 minutes. Also, the vibration part H□x *) Is
*%*H,04 inputs may be used, and notification may be made in units of one interval based on the number of intermittent vibrations of each vibrating part.

As described above, according to the present invention, the current #mK Since the corresponding vibrating part is driven, it is easy to know the time, and the busy time does not shift when you touch it with your finger like in the past. There is no need to worry about disturbing the people in the surrounding area due to the noise generated, and it is possible to easily change the time between 4 and 11 o'clock, and it is possible to easily add an alarm tower, etc.

By switching the drive signal of the vibrating section to an audible frequency, it can also be used as an alarm sound source.
