Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is a dial system that converts a pre-entered or stored telephone number into a dial sound and outputs it instead of actually operating the dial (or push button) of a telephone. This invention relates to a sound generator.

[Conventional technology]

As a conventional dial tone generator, the dial tone output section, such as a speaker, is brought close to the transmitting section of the telephone, and then the execution switch is pressed.
Some devices output a dial tone to the above-mentioned transmitter.

[Problems with conventional technology]

In the conventional device described above, in order to output the dial tone, the operator had to press the execution switch while holding the transmitter of the telephone, which made the operation very cumbersome and troublesome.

[Purpose of invention]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a dial sound generating device that is easy to operate when outputting a dial sound.

[Key points of the idea]

In order to achieve the above object, the present invention detects the 400Hz oscillation sound that is emitted when the handset is removed from the telephone, and starts outputting the dial tone after a predetermined period of time after detecting this oscillation sound. This is what I did.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of an electronic wristwatch incorporating an embodiment of the present invention. In the figure, a watch main body 1 includes a display section 2 made of a liquid crystal display device for displaying the time, telephone number, etc., and a microphone that also serves as a speaker for outputting a dial sound and detecting the oscillation sound of the telephone. 3. Note that a part of the display section 2 includes a display body 2a for notifying that the oscillation sound of the telephone, which will be described later, has been detected. Furthermore, an annular sound insulating member 4 made of an elastic material such as rubber is attached so as to surround the display section 2 and the speaker/microphone 3. The sound insulating member 4 can be brought into close contact with the transmitting part and the receiving part of the telephone, and when the sound insulating member 4 is brought into close contact, ambient noise is blocked from the speaker/microphone 3. Also, on the side of the watch body 1, there is a mode changeover switch S1 for alternately switching the display mode of the display section 2 between watch mode and telephone mode, and a mode changeover switch _S1 for switching the display mode of the display section 2 alternately between watch mode and telephone mode. A search switch _S2 that is operated when searching for a number, and a correction switch _S3 that is used to adjust the time, set a telephone number, etc. are provided.

Next, FIG. 2 is a block diagram showing the internal configuration of this embodiment. In the figure, switches S ₁ to _{S 3} ,
The display section 2 and the speaker-cum-microphone 3 are the same as those shown in FIG. Each of the above switches S ₁ ~
When _S3 is operated, each block is controlled by the switch control section 10 based on the operation.

First, when the display mode is switched to clock mode by operating the mode changeover switch _S1 , the clock signal of a constant frequency output from the oscillator 11 is divided by the frequency divider circuit 12, and further 13, it is counted a predetermined number of times, and time data such as hours, minutes, seconds, etc. is obtained. This time data is then displayed on the display section 2 by the switching display drive section 14.

In the above clock mode, press the mode selector switch S ₁
When is operated, the display mode switches to telephone mode. In this mode, setting of telephone number, output of dial tone, etc. are performed as shown below.

First, the storage unit 15 includes a plurality of storage areas, and is capable of storing names and telephone numbers of a plurality of people in each of the storage areas. Therefore, when the search switch _S2 is operated in the telephone mode, each storage area in the storage section 15 is sequentially designated. Then, the contents of the designated storage area (name and telephone number for one person) are temporarily stored in the one-page storage section 16 and displayed on the display section 2 by the switching display drive section 14. Note that while looking at the display contents on display section 2, press search switch _S2 to select memory section 1.
After specifying the desired storage area in step 5, press the correction switch.
By operating _S3 , the contents can be changed and set for the storage area.

In addition, in the telephone mode, the amplifier 17
An operation command signal is being sent to. If the telephone oscillation sound (usually 400
Hz), this oscillation sound is transmitted to the amplifier 17.
The oscillation sound is amplified and detected by the oscillation sound detection section 18.
When the oscillation sound detection section 18 detects an oscillation sound, it sets the flip-flop 19 and its Q output becomes H (high) level. Then, this H level signal causes the display section 2 to be switched on via the switching display drive section 14.
When the display 2a inside lights up, the timer section 20 starts timer operation, and furthermore, the tone dial waveform generation section 21 and amplifier 22, which will be described later, are activated.
starts working. However, since the gate 23 is not yet open at this time, no tone dial waveform is output from the tone dial waveform generator 21.

Next, when three seconds have passed since the timer section 20 started the timer operation, it outputs a three second elapsed signal a and opens the gate 23. Then, the phone number stored in the 1-page storage unit 16 (that is, the phone number stored in the storage unit ₁₅ by operating the search switch S2)
(telephone number read out from the telephone number) passes through the gate 23 and is sent to the tone dial waveform generator 21.

The tone dial waveform generator 21 generates a tone dial waveform corresponding to the received telephone number. This tone dial waveform is amplified by an amplifier 22 and output as a dial sound from the speaker microphone 3. Therefore, the dial tone will be output 3 seconds after the oscillation tone of the telephone is detected. While the dial sound is being output, the above-mentioned oscillation sound is not detected.

When the tone dial waveform generator 21 finishes outputting the tone dial waveform, it outputs a termination signal c. This end signal c resets the flip-flop 19 via the OR circuit 24. Then, the display body 2a in the display section 2 is turned off, the timer section 20 stops its timer operation and returns to the initial state, and furthermore, the operations of the tone dial waveform generation section 21 and the amplifier 22 are stopped. In addition,
If the tone dial waveform generating section 21 does not output the end signal c even after 10 seconds have passed after the timer section 20 starts the timer operation, the timer section 20
A 10 second elapsed signal b is output from then on, and the flip-flop 19 is reset via the OR circuit 24.
It returns to the initial state in the same way as when the above-mentioned end signal c is output. Here, the case where the end signal c is not output is a case where no data is stored in the one-page storage section 16, that is, a case where a desired telephone number is not specified by the search switch _S2 .

To make a call using the device of this embodiment as described above, first switch to the telephone mode with the mode changeover switch _S1 , and while looking at the name and telephone number displayed on the display section 2, press the search switch _S2 . Specify the desired phone number. Next, the receiver of the telephone is brought into close contact with the sound insulating member 4 shown in FIG. 1, facing the same.
Then, the oscillating sound (400Hz) coming from the receiver above
has been detected, and display body 2 to notify that fact.
a lights up. Therefore, the operator
After confirming that the is lit, place the transmitter of the telephone in close contact with the sound insulating member 4, facing the sound insulating member 4 within 3 seconds.
Then, when 3 seconds have elapsed after the display 2a is turned on, output of the dial tone to the above-mentioned transmitting section is started.

In this way, in this embodiment, the dial tone is output by detecting the oscillation sound of the telephone, so it is only necessary to place the device on the receiver and the transmitter, and the operator does not have to touch the receiver as in the conventional case. There is no need for cumbersome operations such as pressing the execution switch while holding the device.

Note that the time from when the oscillation sound is detected until the output of the dial sound starts is not limited to 3 seconds as described above, but may be set as appropriate according to operational necessity.

Further, although the display 2a is used as a means for notifying the detection of the oscillation sound, a buzzer or the like may be used instead to notify the detection audibly.

Furthermore, in addition to the above-mentioned wristwatches, the present invention also provides
For example, it can be applied to various electronic devices such as small electronic calculators.

[Effect of idea]

According to the present invention, when outputting dial sound,
There is no need for the troublesome operation of pressing an execution switch, and calls can be made with very simple operations.
