The speaker SP is connected to each other, and the second driver 20a is connected to the music signal input line IN1 and the control input line LIR1.

The first driver 10a is composed of an amplifying circuit and the second driver 20a is composed of a signal source.

FIG. 3 is a second embodiment of the present invention, in which a second driver is provided in the first driver 10b including a music signal input / output line IN1 (out1), and a control input / output line LOP1, LIR1. Connect 20b.

The control input line LIP2 of the second driver 20b is connected to the control output line LOP1, and the control output line LOR2 is connected to the control input line LIR1.

The music signal output line out2 of the second driver 20b is connected to the music signal input line IN1 of the first driver 10b, and the speaker SP is connected to the music signal of the first driver 10b. To the output line out1.

The first driver 10b uses an internal signal source and an amplification circuit, and the second driver 20b uses a signal source.

4 is a third embodiment of the present invention. The music signal output line out1 of the first driving unit 10c including the music signal input / output lines IN1, out1 and the control input line LIR1 is shown in FIG. The speaker SP is connected, and the second driver 20c is connected to the music signal input line IN1 and the control input line LIR1.

The second driver 20c includes a music signal input / output line IN2, an out2, and a control input / output signal LIR2, LOR2, and LOP2, and controls the input and output of the second driver 20c. The driving section of the third driving means 200 through the control input / output lines LIR3, LOR3 and the music signal output line out3 on the output lines LOP2, LIR2 and the music signal input line IN2. Connect 30c.

The first driver 10c is composed of an amplifying circuit, the second driver 20c is composed of a signal source and a transmitter, and the driver 30c is composed of a signal source.

On the other hand, although the microcomputer 300 is connected to the control input and output lines of the respective drive units 10a to 10c, 20a to 20c, and 30c, the microcomputer 300 is not shown.

In the above-described scheme, conceptually explaining the first diagram based on FIG. 1, the left block in the drawing is close to the amplifier and the right block is close to the signal source when each unit is connected.

At this time, the priority is that the unit on the left side is high. For example, when the unit 10, that is, the first driving unit 10 is completely “off,” the units connected to the right side may output a music signal to the speaker SP. It becomes impossible.

For example, when the unit 20, i.e., the second driver 20 is interrupted at the left and right units at the same time, the unit on the right side is normally ignored and the interrupt on the left side becomes the priority. And when each unit connected in the middle only plays the role of transmitter, if you turn off the power in each unit and back up only the part corresponding to the buffy, the music signal of the signal source on the last right is output. There will be no.

This will be described in more detail as follows.

As shown in Fig. 2, in the unit-to-unit connection system of the most common acoustic equipment in which the first driver is an amplification circuit and the second driver is a signal source, it is necessary to know one's unit operation to another unit and to operate a unit necessary when it is operated. By the control of the interface microcomputer 300 between the control output line LOR2 and the control input line LIR1 for receiving the control output signal OR from the control output line LOR2 of another unit so that the unit can operate. The remote control of the first driving unit 10a is performed. An example of the first driving unit 10a may be a power amplifier. Examples of the second driving unit 20a may include various players such as a compact disc player, a digital audio tape, and a tuner. I can lift it.

On the other hand, as shown in FIG. 3, in the system in which the first driver 10a is a tech amplifier or a car-stereo internal signal source and the amplifying circuit second driver 20b is a signal source that is a general player, the first driver 10b. In the case where the internal signal of the s) is output through the speaker SP, the control output line LOP1 and the control input line LIP2 become a logic “high” level to turn off the second eastern part 20b.

On the other hand, when the signal of the second driver 20b is output through the speaker SP, the control output line LOR2 and the control input line LIR1 are at a logic “high” level, so that the interior of the first driver 10b is maintained. While the signal is "off", the signal is output by setting the logic "low" level between the control input / output lines LIR2 and LOP1.

In addition, as shown in FIG. 4, in the system in which the first driving unit 10c is the power amplifier, the second driving unit 20c is the signal source, and the driving unit 30c of the third driving unit 200 is the auxiliary signal source. When the two drive unit 20c operates as a signal source, the control input / output lines LIR1 and LOR2 are set to a logic “high” level so as to remotely control the first drive unit 10c operated as an amplification unit, and control output. The drive unit 30c is stopped by making the logic “high” level between the line LOP2 and the control input line LIP3.

On the other hand, when the drive unit 30c becomes a signal source, the control input / output lines LIR2 and LOR3 become logic "high" levels to stop the second drive unit 20c and at the same time control / output line ( LIR1) and LOR2 are at the logic "high" level so that the second driver 20c operates as a transmitter.

In addition, in order to operate the drive unit 30c during the operation of the second drive unit 20c, the second drive unit 20c is stopped and controlled while the timer within 2 to 3 seconds is “on” as shown in FIG. When the output line LIP3 and LOP2 are at a logic "low" level, the driving unit 30c is "on" and the second driving unit 20c is stopped to function as a transmitter.

6 is an interrupt processing flowchart of a control input line for automatically stopping one's own unit during operation of another unit. When the control input line is logic “high”, the player stops (S1) and the control output line LOR2. When the play key is input while the logic is "low" and the control output line LOP2 is logic "high" (S2), the second driving unit 20c becomes a player mode operated as a signal source (S3).

The operation of the timer is as described above (S4).

On the other hand, the interrupt processing flowchart of the control output lines becomes the player mode when the control output lines are each in the logic "high" state as shown in FIG.

Referring to FIG. 4, when the control output line LOP2 becomes logic “high”, the driving unit 30c does not operate. When the control output line LOR2 becomes logic “high”, the first driving unit 10c Is operated, signals from the signal source of the second driver 20c, which is various players, are output to the speaker SP through the first driver 10c.

The above interrupt processing of the control output line is the same in other embodiments because the basic principle is the same.

In addition, a flow chart of a control input line for allowing the unit to operate when another unit is operated is shown in FIG. 6A. Referring to FIGS. 3 and 4, first, the control input line LIR2 is a logic “ In the high state, it is checked whether the control input line LIP2 is in the logic "high" state (S1).

At this time, when the control input line LIP2 is not in the logic “high” state, the player of the second driving unit 20b stops (S2). When the driving unit 30c serving as an auxiliary signal source is connected as shown in FIG. The signal of the auxiliary signal source is output (S3).

In addition, in FIG. 4, when the control output line LOR2 is in the logic "high" state and the control output signal LOP2 is in the logic "low" state, when the play key is input (S4), the auxiliary signal source of FIG. It becomes a player mode to which the signal of the second driving unit 20c is output instead of the signal, and interrupt processing of the control input line is performed.

As described above, the design of this unit varies the operation priority of each unit according to the interrupt applied to the 4-terminal control line for input / output control controlled by the control of the microcomputer 300. Connection is possible.

As described above, this design has a four-terminal control line for input / output control in the unit equipped with the function of the signal source and the amplification unit or the function of the signal source and the amplification unit or the function of the signal source and the transmitter. The amplification section has an effect of enabling bidirectional control of the signal source and the amplification section of the signal source and facilitating the multi-stage connection of each unit.
