Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio device equipped with a logic control mechanism that can be controlled by a remote control switch provided on a cord of headphones connected to an output jack of a main body.

2. Description of the Related Art As an audio device equipped with a logic control mechanism that can be controlled by a remote control switch provided on a headphone cord connected to an output jack of an audio device body, for example, Japanese Patent Application No. 62
There is the year 183998. This is provided with a control circuit for executing operation control of the magnetic tape drive mechanism and one button operation switch means for generating a pulse signal preset to issue a plurality of operation commands of the control circuit, The circuit is configured to perform a mechanism control by providing a detecting means for the pulse signal emitted from the button operating switch means and a control means for issuing a mechanism operation command corresponding to the number of the detected pulse signals. Further, button operation switch means is provided in the middle of the headphone cord to enable remote control operation.

In addition to the above examples, there has been proposed an example in which the control circuit responds to the signal of the operation switch by receiving a remote control operation command with a beep sound and enabling listening with headphones. (No. 121030 of Japanese Patent Application Sho 63).

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a remote control operation, the state I and the state II of the mechanism are ON / OFF of a motor for running a recording medium such as a magnetic tape like a recording state and a recording standby state. If only OFF is different, it is exactly the same in that it is recording and monitoring with headphones, and the state of the mechanism cannot be determined. Therefore, there is a problem in that the current state of the mechanism is memorized or the state of the main body is visually confirmed. Furthermore, since the number of remote control operations within a preset time is used as each operation command input to the mechanism states I and II, the above-mentioned time is always required, and there is a delay in switching the mechanism state, or while maintaining the mechanism state. The problem is that the audio signal circuit cannot be controlled.

The present invention solves the above-mentioned conventional problems, and provides a sound device with a remote controller that does not bother to store the current state of the mechanism by remote control operation. Furthermore, it is possible to freely set the operation start time for changing the state of the mechanism by remote control operation, and it is possible to control the audio signal circuit while maintaining the state of the mechanism as it is. Is provided.

Means for Solving the Problems The audio device of the present invention outputs the reception sound of remote control operation, when switching the state of the mechanism by remote control operation within a preset time, the current mechanism state,
This is an audio device which occurs only when the mechanism state to be switched is different, and the operation of the remote controller is detected within the preset time, and the mechanism is operated until the remote controller operation is completed. It waits for the start of the state switching operation and controls the audio signal circuit.

Effect The audio device of the present invention outputs the reception sound of the remote control operation only when the mechanism state is switched by the remote control operation within a preset time with respect to the current mechanism state. You can confirm the current mechanism status by sound and confirm it.

Further, even if the number of times the remote controller is operated within a preset time period is detected and the reception sound is output, the operation start time is waited for until the operation of the remote controller is completed until the remote controller operation is completed. It is possible to control.

In addition, even if the current state of the mechanism and the state of the mechanism commanded by the number of times the remote control is operated are the same, no acceptance sound is output and the state of the mechanism is maintained while the remote control operation is completed. It is possible to control the audio signal circuit.

Example An audio device according to an example of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment thereof, in which the audio signal circuit in the tape recorder shows a recording state.

In FIG. 1, a voice signal input from the recording input terminal 1 is amplified by a recording amplifier 2, output from a recording head 3 and recorded on a magnetic tape, and also via an amplifier 4 and a volume adjusting variable resistor 5. Is input to the power amplifier 6. The audio signal amplified by the power amplifier 6 can be monitored by the headphones 8 connected to the output jack 7. 9
Is a remote control switch provided in the middle of the cord of the headphone 8 and is connected to the input terminal pulled up by the resistor 11 of the control circuit 10. Control circuit 10 motor mechanism
It is configured to control the driving transistor 15 and the resistor 16 of 14 and to control the oscillator 17 for generating the reception sound.

Here, for example, it is assumed that the operation command is set so that the pulse signal generated by pressing the remote control switch 9 is in the recording state when the pulse signal is one and in the recording pause state when the pulse signal is two. The circuit 10 turns on the motor 14 of the mechanism in response to the operation command in the recording state, and turns off the motor 14 in response to the operation command in the recording pause state. Further, the control circuit 10 issues an operation command for dial tone output to operate the oscillator 17 and output a predetermined dial tone to the headphones 8 only when the mechanism operation command is different from the current mechanism state. is there. Below, the recording state is the mechanism state I, and the recording pause state is the mechanism state.
As II, the operation will be described based on the flowcharts of FIGS. 2 and 3.

First, in the flowchart of FIG. 2 showing the first embodiment, from the mechanism state I of step 1, the first pulse signal is input by operating the remote control switch 9 (step 2), and the pulse signal of the second pulse signal is input. The presence or absence is determined in step 3. In 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, step 4
After outputting the acceptance sound II, the switching operation from mechanism state I to mechanism state II in step 5 is executed,
Switch to mechanism state II of step 6 and hold. Here, the reception sound II emits a transmission sound corresponding to the two pulse signals to the headphone 8 side. Mechanism state of step 6
In the same manner as described above, the remote control operation from II outputs the acceptance sound I to switch to the mechanism state I if it is once, and maintains the mechanism state II which is the current state if it is twice. By doing this, if the current mechanism state and the mechanism state you want to set by remote control operation are the same, the current mechanism state is maintained without outputting a reception sound. After outputting the corresponding acceptance sound, the mechanism state can be switched, so that the current mechanism state can be confirmed.

Next, in the flowchart of FIG. 3 showing the second embodiment, from the mechanism state I of step 11, the remote control switch 9 is turned ON once to step 12, and this remote control switch is set for a preset time (T ₁ if OFF in seconds), to step 14 to determine the presence or absence of the pulse signal by the second remote control, if holding the T more than ₁ second oN state,
The mechanism state I is maintained by waiting in step 15 until the remote control switch is turned off. Also, in step 14, 2
When there is no second pulse signal, the mechanism state I is maintained similarly, but when there is a second pulse signal, the acceptance sound II is output in step 16 and the remote control switch 9 is OF
Step 1 until the second pulse signal disappears as F
After waiting at 7, from mechanism state I to mechanism state I
The switching operation to I is executed in step 18, and step 19
Complete the switch to mechanism state II. Step 19
Similarly, in the control from mechanism state II, the number of pulse signals input by turning on the remote control switch 9 and the operation start for setting the state of the mechanism corresponding to this number of pulse signals until the remote control switch is turned off. During that period, we will wait. In this way, the current mechanism state can be confirmed by the received sound, and the time to start the operation of the mechanism can be freely set by the remote control switch based on the mechanism operation command.

A third embodiment of the present 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 connected to the resistor 11 of the control circuit 10.
Connected to the input pulled up by
It is connected via 12 to the muting terminal 13 of the power amplifier 6. Here, the operation of the control circuit 10 is as shown in the flowchart of FIG. In Fig. 3, mechanism state I is recording state with motor 14 turned on, mechanism state II
When the motor 14 is turned off to enter the recording paused state, the pulse signal generated from the remote control switch 9 is designated as the recording state when the pulse signal is one and the recording paused state when the pulse signal is two. When the mechanism is in the recording state, if the remote control switch 9 is pressed once, the control circuit 10 operates so as to wait for the remote control switch 9 to be turned off while maintaining the recording state in step 15, while the remote control switch 9 is in the meantime. Since the diode 12 connected to 9 turns on, the power amplifier 6
Does not output the monitored audio signal due to muting. Even in the recording pause state, the same applies if the remote controller switch 9 is operated twice and the second time is pressed. When the remote control switch 9 is turned off, the process moves from step 15 to step 11, the muting is released, and the state of recording while monitoring is restored.

The control circuit 10 is provided with an output for muting control, and the third
The same applies when the muting output is output in step 15 and step 25 in the flowchart of the figure.

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

As described above, according to the present invention, a dial tone 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 and the current mechanism state are different. Therefore, there is no difference in listening to the sound by wearing headphones, and when only the mechanism state is different, the trouble of remembering the mechanism state of the main body or visually confirming the main body can be eliminated, The operability of the remote control can be greatly improved.

Further, in order to distinguish the mechanism operation command contents according to the number of pulse signals issued by remote control operation, it is necessary to detect the number of pulse signals within a preset time.
Therefore, it takes the preset time for the mechanism to start the operation according to the operation command from the start of the remote control operation, which causes the operation delay. However, in the present invention, since the operation completion time of the remote controller can be freely set, even if the above-mentioned operation delay is required, no trouble will occur. On the other hand, since the operation can be started at the desired time, when switching from the recording pause state to the recording state, you can immediately start recording without missing the recording opportunity, and without losing the beginning of the recorded content It is possible to greatly improve the sex.

In addition, since the audio signal circuit can be controlled while maintaining the mechanism state with the remote control switch, when recording, for example, even if you are wearing headphones in your ears and monitoring for recording, you can talk to other people, When you want to check the sound, or when the recording monitor level is too high while recording with a microphone and howling occurs, it is possible to respond while continuing recording. Thus, the convenience of the remote controller can be greatly improved.
