Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an audio device equipped with a one-piece control mechanism that can be controlled by a remote control switch provided on the cord of headphones connected to the output jack of the main unit. .

Prior Art An example of an audio device equipped with a logic control mechanism that can be controlled by a remote control switch provided on the cord of a headphone connected to the output jack of the audio device main body is the patent application No. 62
There is a year number 183998. This device includes a control circuit for controlling the operation of the magnetic tape drive mechanism, and one button operation switch means for generating preset pulse signals to issue multiple operation commands for the control circuit. The control circuit is configured to control the mechanism by providing means for detecting a pulse signal emitted from the button operation switch means and a control means for issuing a mechanism operation command corresponding to the number of times of the detected pulse signal. Furthermore, a button operation switch means is provided in the middle of the headphone cord to enable remote control operation.

In addition to the above examples, an example has also been proposed in which the control circuit, in response to the signal from the operation switch, announces with a beep that it has received a command to operate the remote control, making it possible to listen to it through headphones. (Patent Application No. 121030 of 1983).

Problem to be Solved by the Invention However, in such a remote control operation, the state of the mechanism and the state of If the only difference is that the recording is monitored using headphones, it is completely the same, and the state of the mechanism cannot be determined. Therefore, there is a problem in that it is troublesome to memorize the current state of the mechanism or visually check the state of the main body. Furthermore, the number of remote control operations within a preset time is determined from mechanism state 1. Since each operation command is input to the II, it always takes a long time beforehand, and there is a problem that there is a delay in switching the mechanism state, and it is not possible to control the audio signal circuit while maintaining the mechanism state. .

The present invention solves these conventional problems and provides an audio device with a remote control that does not require the trouble of storing the current state of meth 1 rhythm by remote control operation. Furthermore, it is possible to freely set the start time for changing the state of the mechanism by remote control operation, and it is an audio device with a remote control that can control the audio signal circuit while maintaining the current state of the mechanism. It provides:

Means for Solving the Problems The audio device of the present invention receives a remote control operation, outputs sound, and when changing the state of a mechanism by remote control operation within a preset time, the sound device detects the current state of the mechanism and the mechanism to be changed. This is an acoustic device that generates the sound only when the 1st rhythm state is different from the 1st rhythm state, and also detects the operation of the remote control within the preset time mentioned above, and also detects the operation of the mechanism for the period until the remote control operation is completed. It waits for the start of a state switching operation and controls the audio signal circuit.

Function: The sound device of the present invention outputs a sound when the remote control operation is received only when the mechanism state is switched by remote control operation within a preset time for the current mechanism state. The current mechanism status can be announced and confirmed by the presence or absence of the mechanism.

Furthermore, even if the reception detects the number of times the remote control is operated within a preset time and outputs a sound, it waits for the start of the operation of the state change of the mechanism until the operation of the remote control is completed. This allows time to be controlled.

Furthermore, even if the current state of the mechanism is the same as the state of the mechanism commanded by the number of times the remote control is operated, the reception desk will not output any sound and maintain the state of the mechanism until the remote control operation is completed. This makes it possible to control the audio signal circuit during this time.

EXAMPLE Hereinafter, an audio device according to an example of the present invention will be explained based on the drawings. FIG. 1 is a block diagram showing the embodiment,
In this figure, the audio signal circuit in the tape recorder is in a recording state.

In FIG. 1, an audio signal inputted from a recording input terminal 1 is amplified by a recording amplifier 2, outputted from a recording head 3, and recorded on a magnetic tape. The signal is input to a power amplifier 6 via a variable resistor 5 for volume adjustment. The audio signal amplified by the power amplifier 6 can be monitored with headphones 8 connected to the output jack 7. 9
9 is a remote control switch installed in the middle of the cord of the headphones 8, and is connected to the input terminal pulled up by the resistor 11 of the control circuit 10. At the same time, the reception is configured to control a sound generator 17 for generating sound.

Here, for example, assume that the operation command is set to be issued so that if there is one pulse signal, the pulse signal is in the recording state, and if there are two pulse signals, the operation command is in the recording pause state. The circuit 10 turns on the motor 14 of the mechanism in response to an operation command in the recording state, and turns it off in response to an operation command in the recording pause state. Further, the control circuit 10 only controls the mechanism operation command when the mechanism operation command is different from the current mechanism state.
An operation command for outputting a beep is issued to operate the first oscillator 17, and a predetermined beep is output to the headphones 8.

Hereinafter, the operation will be described based on the flowcharts of FIGS. 2 and 3, assuming that the recording state is the mechanism state I and the recording pause state is the mechanism state ■.

First, in the 70-wire shown in FIG. 2 showing the first embodiment, from the mechanism state I in step 1, the first pulse signal is input by operating the remote control switch 9 (step 2), and then the second pulse signal is input. Step 3
It is determined by In this step 3, if there is no second pulse signal, the mechanism state I of step 1 is maintained, but if there is a second pulse signal, the process proceeds to step 4, and after outputting the sound ■, the reception goes to step 5. The switching operation from the mechanism state at to the mechanism state ■ is executed, and the switching operation is performed to the mechanism state H in step 6 and held. Here, the reception is to send a tone corresponding to the two pulse signals to the headphone 8 side. Step 6 mechanism status ■
The remote control operation from the above is the same as above, and if it is only once, output reception 31 and switch to mechanism state I,
If it happens twice, the current state of mechanism state ■ is maintained. In this way, if the current mechanism state and the mechanism state you want to set by remote control operation are the same, the reception will not output any sound and maintain the current mechanism state, and if they are different, the remote control operation content The reception desk that supports this can switch the mechanism status after outputting the sound, so it is possible to check the current mechanism status.

Next, in the flowchart of FIG. 3 showing the second embodiment, from the mechanism state (3) in step 11, the remote control switch 9 is turned ON once and the process proceeds to step 12, and then the remote control switch is turned on for a preset time (T + seconds)
If it turns OFF within T1 seconds, the process goes to step 14, which determines the presence or absence of a pulse signal caused by the second remote control operation.
If the state is to be maintained, the mechanism waits in step 15 until the remote control switch is turned off to maintain the mechanism state (2).

In addition, in step 14, if there is no second pulse signal, the mechanism state I is maintained in the same way, but if there is a second pulse signal, in step 16 the reception outputs the sound ■ and turns the remote control switch 9. After turning OFF and waiting in step 17 until the second pulse signal disappears, the switching operation from mechanism state (2) to mechanism state (2) is executed in step 18, thereby completing one step of switching to mechanism state (2). Similarly, for control from mechanism state ■ in step 19, turn remote control switch 9 ON.
The number of pulse signals to be input and the start of operation for setting the state of the mechanism corresponding to this number of pulse signals are performed by waiting until the remote control switch is turned off. In this way, not only can the current state of the mechanism and @ be confirmed by sound, but also the time for starting the operation of the mechanism can be freely set using the remote control switch based on the mechanism operation command.

A third embodiment of the invention is shown in FIG. In this example, in the block diagram of FIG. 1, the remote control switch 9 provided in the middle of the cord of the headphones 8 is
1 and the muting terminal 13 of the power amplifier 6 via the diode 12.
It is connected to. Here, the operation of the control circuit 10 is as shown in the flowchart of FIG. 3 above. In FIG. 3, if the mechanism state I is a recording state with the motor 14 ON, and the mechanism state II is a recording pause state with the motor 14 OFF, then if there is only one pulse signal emitted from the remote control switch 9, the recording state; In both cases, the recording pause state is designated. If the remote control switch 9 is pressed once while the Metsu7ism is in the recording state, the control circuit 1o operates to wait for the remote control switch 9 to be turned off while maintaining the recording state in step 15. Diode 12 connected to remote control switch 9 is O
Therefore, the power amplifier 6 performs muting and does not output the audio signal that was being monitored. Even when in the recording pause state, press the remote control switch 9 twice to
The same thing happens if you keep pressing the button. When the remote control switch 9 is turned OFF, the process moves from step 15 to step 11, cancels the previous ia muting, and returns to the recording state while monitoring.

The control circuit 10 is provided with a muting control output, and a third
Step 15 and Step 2 in the flowchart in the figure.
The same holds true even if the muting output is output in step 5.

Although the above embodiment describes the recording state and recording pause state of the tape recorder, the same applies to other operating states and other audio equipment with a remote control.

Effects of the Invention According to the present invention, as explained above, a beep is output only when the mechanism operation command corresponding to the operation of the remote control switch provided in the middle of the headphone cord is different from the current state of the mechanism. Therefore, if there is no difference in the fact that you are wearing headphones and listening to the audio, but only the mechanical state is different, you can eliminate the trouble of having to remember the mechanical state of the main unit or visually confirming the main unit. , The operability of the remote control is thicker (can be improved).

Further, in order to distinguish the contents of the mechanism operation command according to the number of pulse signals emitted by remote control operation, it is necessary to detect the number of pulse signals within a preset time. For this reason, it takes the preset time for the mechanism to start operating according to the operation command after the remote control operation starts, resulting in an operation delay. However, in the present invention, since the operation completion time of the remote control can be freely set, even if the above-mentioned operation delay is required, no problem occurs. Conversely, since you can start the operation at the desired time, you will not miss a recording opportunity when switching from recording pause state to recording state. Greatly improves mobility.

Furthermore, since the audio signal circuit can be controlled using a remote control switch while maintaining the mechanical state, even if you are wearing headphones in your ears to monitor the recording, you will not be able to hear other people talking to you or hear other people around you. When you want to hear the sound, or when the recording monitor level is too high and causes howling while recording with the microphone, while continuing recording,
It is possible to respond. In this way, the simplicity of the remote control can be greatly improved.
