stereo audio signal (hereinafter simply referred to as audio signal).

cormorant. ) is a headpon jack consisting of contacts into which the left and right signals are input, and a 0 and ground pole (2 contacts, 1 pole). Note that these constitute the main body of the headphone stereo. Further, 4 is a headphone plug having two contacts and one pole corresponding to the two contacts and one pole of the jack, 5 is a muting switch, and 6.7 is a left and right headphone unit. These components constitute headphones.In conventional headphone stereos, when it is desired to temporarily cut off (mute) two audio signals, the muting switch 5 of the headphones is turned off.

However, with this method, there is no heat during the meet.

Even if the tape drive motor (not shown) rotates.

continues, so the tape (not shown) is running. Therefore, when you turn on the muting switch 5 and listen to the audio signal again, the tape (not shown) is running. The drawback was that it was not possible to hear continuous audio signals. .

Also, Figure 2 shows a conventional headphone stereo.

It is.

In order to eliminate the drawbacks described in FIGS. 1 and 5 in conventional headphone stereos, etc., we have devised an idea.

The device shown in Figure 2 was used. Namely, No.

The device shown in Figure 2 has the same muting circuit as shown in Figure 1.

is provided separately to temporarily stop the motor drive.

It is something that can be done.

In FIG. 2, first and second sub-switches 22 and 23 are provided separately from the power switch 13.

This allows the tape drive motor 12 to be temporarily stopped.

The second sub-switch 23 is provided on the plug side, and is connected as shown in FIG. 2 by fitting with the jack provided on the set side. Also, the first sub-switch 22
is off when the second sub-switch 23 is connected, and is on when it is not connected.

10 As is clear from Figure 2, the 1st and 2nd supply switches.

Connect the switch 23 and turn on the power switch 13.

For example, the user can drive and stop the tape drive motor 12 at hand.

can be done.

However, in this case, in addition to the head and five-phone jack 3 shown in FIG. 1, the second sub-switch is used.

A separate jack is required to connect the headphone jack 3, a headphone plug 4°, and the second sub-switch 23.

0 when sharing the jack and plug , 6.

Also, the configuration for sharing is complicated and requires a lot of wires.

The disadvantage was that the number also increased.

The object of the present invention is to eliminate the drawbacks of the prior art mentioned above.

Eliminates the operation of a traditional muting switch.

It is an object of the present invention to provide a motor temporary stop device that can also control the drive stop of a tape drive motor. - In order to achieve the above object, in the present invention, the left signal and right signal of the audio signal are respectively inputted. - It has two contacts and a ground pole, and corresponds to the two contacts and the ground pole. 2 contacts 1
The two contacts each have a headphone unit and a headphone unit.

It was decided to provide a motor.

Further, in the present invention, in order to achieve the above object, the both ends of 61 are respectively connected to two of the two contacts and the ground pole of the jack, and υ is connected by the on/off operation of the muting switch. The tape is turned on and off by the switch means.

A control stage for driving and stopping the drive motor is provided.

Hereinafter, the present invention will be explained using the drawings.・FIG. 3 is a circuit diagram showing an embodiment of the motor temporary stop device of the present invention. In the figure, the same parts and parts as in Figure 1.2 are designated by the same reference numerals 10, 8 is a capacitor, and 9 is a capacitor.

It will be played and listened to on Dohon Ninit 6.7.

This embodiment uses a muting switch 5.

Using the tape, mute the audio signal at the same time.

This is to temporarily stop the drive motor 12. .

This operation will be explained below.　　　　.

In the circuit shown in FIG. 3, when both the power switch 13 and the muting switch 5 are turned on, the voltage output from the battery e 14 changes from the power switch 13 to the muting switch 5. resistance 6
0. Headphone jack 3. Headphone plug 4. Meeting switch 5. Headphone unit 6, headphone unit Z The muting switch 5
．． The signal is applied to the base of the transducer 9 through the headphone lug 4° and the headphone jack 3.

As a result, the transistor 9 is in an on state.

Transistor 10 is in an off state, transistor 11° is in an off state, and tape drive motor 12 is operated.

Since DC current is supplied, it will be driven by 1.P By the way, while using the headphone stereo.

When the muting switch 5 is turned off, the tape drive is set to 0, as is clear from the above.

- DC current is no longer supplied to the motor 12, causing a sound.

At the same time as the voice signal is cut off, the drive of the motor 12 is also stopped.

In this embodiment, muting switches 5 are provided on the input lines 4a and 4b for the left and right audio signals;

The switching switch 5 may be provided on one of the input lines 4a, 4b of the left signal and right signal 5, and on the common ground line 4c.

Furthermore, if the terminals of the transistor 9 and the end of the resistor 3α on the headphone jack 3 side are connected at different points, they are connected as two connections of the jack.

It doesn't matter if it is connected to any of points 1&.

Of course Ito.

As is clear from the above description, the present invention provides various advantages.

For example, a connector with the same configuration as before without increasing the number of jacks and wires in the set.

to turn off the muting switch.

This has the effect of being able to stop the rotation of the tape drive motor by just doing this. Therefore, unnecessary power consumption is eliminated.

In addition to saving energy when muting,
When listening to the audio signal again, follow the above steps.

When opening the continuous continuation of the audio signal during NEET.

I can do it.
