Reference numeral 4 denotes a control circuit constituted by a microcomputer or the like as in the prior art. This control circuit 4 basically comprises a CPU, a ROM, a RAM, an input port, and an output port as shown in FIG. In addition, a program for controlling the CPU is written in the ROM, and the CPU fetches necessary external operation data from the operating device 5 connected to the input port according to the program, or transmits data to and from the RAM. It performs arithmetic processing while transmitting and receiving data, and outputs processed data to a display 6 connected to an output port as needed, and displays the processed data, and outputs the processed data to each circuit to control the circuit operation.

Reference numeral 7 denotes a microphone position specifying circuit, which supplies setting position information of the microphone 10 to the control circuit 4 by a setting position specifying switch (not shown) of the microphone 10 provided in the microphone position specifying circuit 7.

The karaoke apparatus thus constructed is operated by the operating device 5.
When the user designates a karaoke performance song, the operation data of the operation device 5 is supplied to the control circuit 4, and the display contents of the karaoke performance song corresponding to the operation data are displayed on the display device 6 and at the same time, the accompaniment music reproducing device is displayed. 1 to reproduce accompaniment music, and at the same time, control the karaoke unit 2 to perform signal processing such as key control and vocal cut of accompaniment music.

Further, the control circuit 4 controls the microphone mixing balance control unit 3, and a microphone input audio signal from the microphone 10 is applied to an input terminal 3a of the microphone mixing balance control unit 3, and an echo is added by an echo circuit 3c. After that, the accompaniment music signal applied to the input terminal 3b is mixed with the adders 3d, 3e, 3f, 3g.

The position of the microphone 10 is displayed on the display 6 at the same time as the signal of each channel is delayed.

The microphone mixing balance control unit 3
For example, when the setting position of the microphone 10 is the rear right seat 8d as shown in the figure, the level of the microphone input audio signal level to the rear right speaker 9d (RR channel) Adjust the VR7 adjuster to lower the mixing level, adjust the level adjuster VR5 to the rear left speaker 9c (RL channel) in the same way, lower the mixing level slightly, and adjust the front and left speakers 9a, 9b (FL, FR).
Channel) can be adjusted without lowering.

The rear right speaker 9d near the position of the microphone 10
The karaoke performance may be performed by lowering only the mixing level of the (RR channel) with the level adjuster VR7.

In this manner, the mixing level to the speaker 9d closest to the position of the microphone 10 is reduced by a predetermined amount, and the mixing level to the speaker 9c next to the microphone 9c is slightly lowered, so that it is possible to suppress howling. Further, the effect of preventing the occurrence of howling can be improved only by lowering the mixing level to the nearest speaker 9d.

Also, the output level of the mixing signal of each channel can be adjusted by the signal level adjusters 3h, 3i, 3j, 3k to change the balance of the output level of each channel. In this case, for example, as shown in the figure, by lowering the output level to the speaker 9d closest to the position of the microphone 10 and slightly lowering the output level to the speaker 9c closest to the microphone 10, it is possible to make howling less likely to occur as described above. It is.

That is, the speaker 9d close to the karaoke singer
Even if the microphone mixing level or the output level of the singer is lowered within a predetermined range, the singer can hardly feel that the level has dropped, and can hear his / her voice well without feeling uncomfortable in karaoke performance. That is, by changing the balance and output level of the mixing output signal within a range that does not impair the feeling of being wrapped in the sound, it is possible to suppress howling without causing unnaturalness.

The balance of the mixing microphone level and the accompaniment music level can be separately adjusted by adjusting the level adjusters VR1 to VR8. For example, the amount of reduction of the accompaniment music level to the speaker 9d closest to the position of the microphone 10 can be set. As described above, the mixing microphone level can be lowered. Or, conversely, the accompaniment music level can be lower than the mixing microphone level.

As described above, when the mixing level is changed to exceed the predetermined range, the localization of the sound image changes, and it is sensed that the balance position of the localization of the sound image has changed. In such a case, the output signal of each channel is delayed, and the sound image localization can be corrected by moving the sound image localization based on the delayed amount of delay. Can be eliminated.

For example, the speaker closest to the microphone 10 position
When the level of the 9d RR channel is lowered, the signal delay circuits 3m, 3n, and 3p do not change the levels of the other FL, FR, and RL channels to compensate for the change in the balance of sound image localization caused by this level drop. By giving a signal delay and canceling the sound image movement caused by lowering the output level of the RR channel speaker 9d by the sound image movement caused by delaying the output signals of the other FL, FR and RL channels. Can be.

The delay amounts of the signal delay circuits 3m, 3n, 3p, and 3q vary according to the amount by which the level is lowered, and the level of not only the speaker 9d closest to the microphone 10 but also the level of the next speaker 9c, for example. Even when the value is lowered, sound image localization without discomfort can be obtained by the same processing.

When performing level control of a plurality of channels, the channel whose level has been lowered the most may be used as a reference, and the channel whose level has been lowered next may be given a delay amount according to the level difference. Also, a delay may be given to the channel whose level has been lowered the most.

As described above, the complex signal processing of the karaoke unit 2 controlled by the control circuit 4 and the microphone mixing balance control unit constituted by various controllers, mixing circuits, delay circuits, and the like is performed by a DSP (Digital Signal Processor).

The level comparator 13 compares sound collection signal levels sequentially collected by the microphone 10 and supplies the comparison signal level to the control circuit 4 via the microphone position designation circuit 7. Then, the setting position of the microphone 10 can be automatically detected.

That is, the signal sound from the signal sound generator 12 is transmitted through the signal switch 11 to the speakers 9 of the FL, FR, RL, and RR channels.
a, 9b, 9c, 9d. The signal switch 11 is controlled to be switched by the control circuit 4. For example, first, a signal sound is supplied to the FL channel only for a predetermined time and the speaker 9a is supplied.
Output more. The output signal sound of the speaker 9a is
, And the sound collecting level is supplied to the level comparator 13 for recording.

Next, a signal sound is supplied to the FR channel for a predetermined time, and a signal sound is output from the speaker 9b. The output signal sound of the speaker 9b is collected by the microphone 10 in the same manner as described above, and is sent to the level comparator 13. Record. Next, the output signal sound of the speaker 9c of the RF channel is converted to the microphone as described above.
The sound is collected at 10 and recorded in the level comparator 13.

As described above, by sequentially recording and comparing the sound collection levels of the FL, FR, RL, and RR channels, it is determined that the channel having the highest sound collection level is the set position of the microphone 10, and Position can be detected automatically,
