〔Example〕

Hereinafter, the details of the present invention will be specifically explained with reference to the drawings.

The drawing is a block diagram showing a circuit of an embodiment of a karaoke performance device according to the present invention.

In the figure, 1 is a microphone, 2 is an amplifier, 3 is a synthesizer, 4 is a mixing circuit (MIX), 5 is a speaker, and 6
7 is a differential amplifier, 7 is a rhythm discriminator, and 8 is a synthesizer control circuit.

The microphone 1 is connected to an amplifier 2, which is coupled to a mixing circuit 4 and a differential amplifier 6.

Synthesizer 3 is coupled to mixing circuit 4 , differential amplifier 6 and synthesizer control circuit 8 .

The differential amplifier 6 is coupled to a rhythm discriminator 7, and the rhythm discriminator 7 is coupled to a synthesizer control circuit 8.

The microphone 1 converts the singer's singing voice into an electrical signal and sends it to the amplifier 2, and the amplifier 2 sends this electrical signal to the mixing circuit 4 and the differential amplifier 6.

The synthesizer 3 automatically plays accompaniment music for singing that has been selected in advance by the singer, that is, it plays synthesized music using a card installed in a music selection device built into the synthesizer control circuit 8. The played music is sent to a mixing circuit 4 and a differential amplifier 6.

The mixing circuit 4 mixes the electrical signals of the singing voice and the synthesizer's sound from the amplifier 2 and the synthesizer 3 and sends the mixture to the speaker 5, and the speaker 5 uses these electrical signals to mix the singing voice and the synthesizer's sound instead of the voice. emits.

The differential amplifier 6 selects the synthesizer sound component from the electrical signals of the synthesizer sound component and the singer's voice component sent from the synthesizer 3 and the amplifier 2. c1rrI is used to generate only the electric signal of the singer's singing voice and send it to the rhythm 'I'll separate device 7.

The singing voice and the synthesizer sound emitted from the speaker 5 are picked up by the microphone 1, sent to the amplifier 2, and input to the differential amplifier 6, but the differential amplifier 6 suppresses the performance sound of the synthesizer. Since the electrical signal is essentially just the singing voice, there is no problem in determining the progress of singing, and there is almost no problem with the time lag during this time.

The rhythm discriminator 7 is a device for discriminating the rhythm of the displacement of an electric signal due to the loudness of the singing voice sung by the singer in accordance with the notes of the song, and is a device for discriminating the progress state of the song sung by the singer.

The synthesizer control circuit 8 causes the synthesizer 3 to perform using a card in which the rhythm, melody, chord, tone quality, etc. necessary for the performance of the music are recorded in advance, and the performance speed is determined by the rhythm discriminator 7 of the singer. Automatically adjusts to the rhythm of the song's progress.

The performance speed adjustment device built into the synthesizer control circuit 8 compares the rhythm determined by the loudness of the singer's song from the rhythm discriminator 7 with the rhythm of the selected song, and determines the rhythm of the singer's song. The synthesizer 3 is operated at a performance speed that matches the performance speed.

The synthesizer control circuit 8 is also provided with a volume control dial, a tone quality control dial, a playback button, etc. (not shown).

Furthermore, it is recommended that a filter be provided between the operational amplifier 6 and the rhythm discriminator 7 to block external noise.

Then, a singer who is a user of the karaoke uses a microphone 1 to sing a song according to a predetermined song card, which is sent from the synthesizer 3, passes through the mixing 4, and is emitted from the speaker 5. For example, as mentioned above, the singer's singing voice and the synthesizer sound are separated by amplifier 2.
The singing voice and the synthesizer sound are amplified by the mixing unit 4 and mixed by the mixing unit 4, and the singing voice and the synthesizer sound are emitted from the speaker 5. This device can be used as a karaoke machine.

At the same time, as described above, the singer's singing voice and the synthesizer sound are subjected to differential amplification +rr6 to suppress the synthesizer sound component, and an electrical signal of only the singing voice is sent to the rhythm discriminator 7.

The electrical signal of the singing voice whose rhythm has been determined by the rhythm discriminator 7 is sent to the synthesizer control circuit 8, and the synthesizer control circuit 8 determines if there is a deviation of more than a certain tolerance between the performance progress of the music and the singing. When the singer's singing voice is seen, the performance speed of the synthesizer 3 is adjusted and controlled to match the singer's singing, so that the singer's singing voice and the accompaniment music from the synthesizer 3 match.

〔Effect of the invention〕

Since the present invention is configured as described above, according to the present invention, the performance speed is automatically adjusted according to the progress of the singer's song, and the accompaniment music is played along with the singer's song. Therefore, it is possible to provide a karaoke performance device that allows many singers with a low musical level to comfortably enjoy singing along with the accompaniment without losing the rhythm of the song.

It should be noted that the configuration of the present invention is not limited to the above-mentioned embodiment. For example, although the synthesizer 3 is used, an optical disk, C, D, or cassette tape can be used in place of the synthesizer, and When a cassette tape is used, it goes without saying that the pitch is also controlled by known means to prevent the pitch from changing abnormally in response to changes in the rhythm by adjusting the playing speed.

Furthermore, regarding the circuit elements of other parts, widely known ones can be used within the scope of the purpose of the present invention,
The present invention encompasses all of them.
