DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a headphone stereo.

<Prior Art> In a wireless headphone stereo, an audio signal is reproduced from a magnetic tape on the main body side, transmitted from a transmission unit, received by a receiver, and listened by headphones connected to the receiver. .

<Problems to be solved by the invention> In such a conventional wireless headphone stereo, the operation sound when operating the operation buttons of the main body is
Since it is not transmitted to the receiver side, the operation sound cannot be heard with the headphones connected to the receiver side, and the receiver side cannot visually confirm the operation. However, there was a problem that the operation had to be confirmed on the main body side.

The present invention has been made in view of the above points, and in a headphone stereo, the confirmation of the operation can be visually confirmed by the sound from the headphones and can be visually confirmed on the receiving side. With the goal.

<Means for Solving the Problems> In the present invention, in order to achieve the above-mentioned object, an audio signal reproduced from a recording medium by the main body is transmitted from a transmission section of the main body, and this is received by a reception section. In a headphone stereo for listening with headphones connected to the receiving unit,
The main body includes an operation sound signal generation circuit that generates an operation sound signal corresponding to an operation of the operation unit of the main body and transmits the operation sound signal from the transmission unit, and the reception unit, based on the received operation sound signal, A display unit is provided for performing a display corresponding to the operation of the operation unit, and the received operation sound signal is output to the headphones.

<Operation> According to the above configuration, when the operation unit of the main body is operated, the operation sound signal corresponding to the operation is transmitted to the reception unit, and the operation sound can be heard by the headphones connected to the reception unit. Since the display corresponding to the operation is performed based on the operation sound signal, the operation can be visually confirmed and the operation can be visually confirmed on the receiving unit side.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an embodiment of the present invention.

The wireless headphone stereo of this embodiment has a main body 1
And a receiver 2 for receiving a transmission signal from the main body 1, and a headphone 3 is connected to the receiver 2. Play (PLAY), stop (STO
P), fast forward (FF), rewind (REW) operation buttons 4a to 4d are provided, and the mechanism controller 5 controls the mechanism section in accordance with the operation of these operation buttons 4a to 4d.

At the time of reproduction, the audio signal reproduced by the magnetic head 6 is amplified by the preamplifier 7 and the Dolby amplifier 8 and given to the main amplifier 10 via the volume 9.
It is given to the transmitter 11 and transmitted to the receiver 2. Receiver 2
Then, the receiving unit 13 receives this transmission signal, and the headphones 3
You will be able to hear stereo sound from.

In this wireless headphone stereo, headphone 3
1 can be connected to the receiver 2 as well as to the output side of the main amplifier 10 of the main body 1 as shown in FIG.

The above configuration is basically the same as that of the conventional wireless headphone stereo.

In this embodiment, in order to enable the receiver 2 side to visually and audibly confirm the operation of the operation unit of the main body 1 in the wireless state, that is, in the state where the headphones 3 are connected to the receiver 2, The main body 1 is provided with an operation sound signal generation circuit 12 that generates an operation sound signal corresponding to the operation of the operation unit and transmits it from the transmission unit 11, while the receiver 2 receives the operation sound signal by the reception unit 13. An operation sound signal is output to the headphones 3, and further, a display unit 18 is provided for performing a display corresponding to the operation of the operation unit of the main body 1 based on the received operation sound signal.

The operation sound signal generation circuit 12 is operated when the operation buttons 4a to 4d such as play (PLAY), stop (STOP) or fast forward (FF) and rewind (REW) of the main body 1 are operated, as shown in FIG.
3k corresponding to each operation as shown in (D)
An operation sound signal of about Hz is set for a preset time T
Occurs within.

This operation sound signal is given to the output side of the main amplifier 10 and is given to the transmitting unit 11, and the transmitting unit 11 sends it to the receiver 2 together with the audio signal from the Dolby amplifier 8.

The display means 18 for performing a display corresponding to the operation based on the operation sound signal includes a pulse conversion circuit 14 for converting the pulse corresponding to the operation sound signal shown in FIG. 2 and the pulse conversion circuit.
The display control circuit 15 that counts the number of pulses of 14 and determines the operation of the operation unit and controls the display based on the count value, the drive circuit 16 that drives the LED, and the operation buttons 4a to 4d of the main body 1 And a display unit 17 having a plurality of LEDs 17a to 17d individually corresponding to.

The pulse conversion circuit 14 converts, for example, the reproduction operation sound signal of FIG. 2 (A) into one pulse, and converts the stop operation sound signal of FIG. 2 (B) into two pulses. , The operation sound signals of FIGS. 2 (C) and (D), three pulses and four
Convert to two pulses respectively.

If the number of pulses is 1, the display control circuit 15 drives the drive circuit 16
The LED 17a corresponding to the reproduction is turned on via, and the LED 17b corresponding to the stop is turned on if the number of pulses is 2, so that the corresponding LEDs 17a to 17d are turned on according to the number of pulses to display the mode. To do.

Next, in the wireless headphone stereo having the above configuration, an operation when the reproduction button 4a of the main body 1 is operated will be described with reference to the timing chart of FIG.

First, as shown in FIG. 3 (A), when the reproduction button 4a is turned on, the operation sound signal generation circuit 12 causes the operation sound signal generation circuit 12 to operate as shown in FIG. 3 (C).
The operation sound signal shown in is generated and output to the output side of the main amplifier 10 and the transmission unit 11. On the other hand, the mechanism controller 5 controls the mechanism unit to perform a reproducing operation, and the audio signal reproduced from the magnetic tape as shown in FIG. 3 (B) is supplied to the main amplifier 10 and the transmitter 11. To be As a result, the operation sound signal and the audio signal shown in FIG.
Will be sent to.

The receiver 2 receives the transmission signal, and the headphones 3 connected to the receiver 2 can hear the operation sound and the stereo sound following the operation sound.

Further, the operation sound signal is converted into a pulse by the pulse conversion circuit 14 of the display means 18, and the display control circuit 15 turns on the LED 17a corresponding to the reproduction based on the number of pulses.

As a result, even in a wireless state, that is, in a state in which the headphones 3 are connected to the receiver 2, it is possible to listen to an operation sound corresponding to the operation of the main body 1 with the headphones 3 and display the receiver 2. It can be visually confirmed by the part 17.

<Effects of the Invention> As described above, according to the present invention, the main body is provided with the operation sound signal generation circuit that generates the operation sound signal corresponding to the operation of the operation unit of the main body and transmits the operation sound signal from the transmission unit, and receives the operation sound signal. The section is provided with display means for performing a display corresponding to the operation of the operation section based on the received operation signal, and outputs the received operation sound signal to the headphones. When the operation is performed, the operation sound corresponding to the operation can be heard through the headphones, and the display corresponding to the operation is displayed on the receiving side, which allows the receiving side to confirm the operation by hearing and sight. become.
