Abstract

PURPOSE:To avoid the trouble of the mode selection by using one switch section so as to select any of the normal mode, the voice fade mode and the multi orchestral accompaniment mode. CONSTITUTION:When moving contacts 23a, 23b are connected to normal mode position contacts 21a, 21b, a signal on inputs 1, 2 is outputted as it is to output, lines 7, 8. When the moving contacts 23a, 23b are connected to fixed position contacts 21c, 21d, a common music signal suppressing a vocal signal of a voice fader 3 is outputted to the lines 7, 8. Furthermore, when the moving contacts 23a, 23b are connected to fixed position contacts 21e, 21f, the output of the vocal signal from the input line 2 is interrupted and only the common music signal from the line 1 is outputted to the lines 7, 8. Thus, a vocal signal of a singer from a microphone amplifier 11 is added to the music signal to attain singing with the orchestral accompaniment.

2. Description of the Related Art FIG. 2 is a circuit diagram showing a conventional karaoke switching device. In FIG. 2, reference numerals 1 and 2 are reproduction signals of commercially available music tapes on which voice multiple recording is performed, tapes edited by a user, compact discs and the like. Input line 1 is used for a music channel, and input line 2 is used for a vocal channel.
Reference numeral 3 is a voice fader, which functions to make the sound of the vocal portion of the reproduced sound small and to play the sound of the accompaniment music played back.

Reference numeral 4 is a switch section for turning on / off the voice fade mode, and 5 is a switch section for turning on / off the multi-karaoke mode. Also, the switch unit 4
4a and 4b are movable contact pieces, and 4c to 4h are fixed contact points. The movable contact piece 4a connects the contact point 4d to the contact point 4e in the voice fade mode to move the movable contact piece 4a.
b operates to switch the contact 4g from the contact 4f to the contact 4h.

The contacts 4c and 4f are connected to the input lines 1 and 2, respectively.
The contacts 4e and 4h are both connected to a common terminal on the output side of the voice fader 1 via a resistor 6. The terminal 4g is the output line 7 of the music channel.
It is connected to the.

Further, in the switch section 5, 5a is a movable contact piece, 5b to 5d are fixed contacts, and the movable contact piece 5a operates to switch the contact point 5c from the contact point 5b to the contact point 5c in the multi-karaoke mode. Also, the contacts 5c, 5
d is connected to the output side of the microphone amplifier 11 via resistors 9 and 10, respectively, and the contact 5c is connected to the output line 8 of the vocal channel. The terminal 5d is connected to the output line 7.

In such a conventional karaoke switching device, when the movable contact pieces 4a, 4b, 5a of the switch sections 4, 5 are switched to the contact points 4c, 4f, 5b, respectively, the input lines 1, 2 are connected. The signals of the music channel and the vocal channel are individually output by being connected to the output lines 7 and 8, respectively.

Next, the movable contact pieces 4a and 4b of the switch section 4
When the switch is connected to the contacts 4e and 4h, the voice fade mode is set, and the voice fader 3 converts the music signal and the vocal signal from the input lines 1 and 2 into a music signal in which the vocal signal is suppressed to a low level. The level is adjusted to and input to the contacts 4e and 4h. Therefore, the level-adjusted common voice fade signal is output to the output lines 7 and 8.

The movable contact pieces 4a and 4b of the switch section 4 are also provided.
Is switched to the contacts 4c and 4f (that is, the voice face mode is released) and the movable contact piece 5a of the switch unit 5 is switched to the contact 5d, the multi-karaoke mode is set and the music channel is input. The music signal from line 1 is output to the two output lines 7 and 8, and vocal output is stopped.

Further, when the switch parts 4 and 5 are operated together, the movable contact pieces 4a and 4b are switched and connected to the contacts 4e and 4h, and the movable contact piece 5a is switched and connected to the contact point 5d. , It doesn't go to the multi-karaoke mode, but goes to one of the voice fade modes.

[0010]

Since the conventional karaoke switching device is constructed as described above, each switch unit 4
Is switched to the voice fade mode and the switch section 5 is switched to the multi-karaoke mode at the same time, one of the voice fade modes is set. For the user, each of the above corresponding to the switch sections 4 and 5 is used. There was a practical problem such as the selection of the mode became confusing.

The present invention has been made in view of the above-mentioned problems, and one of the normal mode, the voice fade mode and the multi-karaoke mode can be selected by one switch section. Therefore, it is an object of the present invention to provide a karaoke switching device that can avoid the trouble of mode selection and can reliably perform karaoke reproduction in a single mode.

[0012]

A switching device in a singing apparatus according to the present invention is connected to each input line of a music channel and a vocal channel and simultaneously selects a music signal and a vocal signal on each input line, A first contact for outputting to each output line of the music channel and the vocal channel, and a voice fader for receiving the music signal and the vocal signal on each of the input lines and outputting the music signal with the level of the vocal signal suppressed to a low level. And a second contact for simultaneously selecting the output of the voice fader and outputting to each output line of the music channel and the vocal channel,
A third contact connected to the input line of the music channel to select only a music signal on the input line and output to each output line of the music channel and the vocal channel is provided. A microphone amplifier is connected to each output line of the vocal channel.

[0013]

The first contact, the second contact, and the third contact in the present invention can be used in the normal mode, the voice fade mode, and the multi-karaoke mode by switching the contact piece or by switching the electronic circuit. Only one can be selected so that the user can select each of these modes without error.
