Abstract

PURPOSE:To provide an accompaniment sound which matches a singer's voice so that he can delightlfully sing a song by providing an accompaniment which approximately matches his singing voice key. CONSTITUTION:The device is provided with a means which extracts the singing voice output reproduced by a player 1, a means which compares the key of the singing voice inputted to a microphone 9 and the key of the singing voice output from the player 1 and outputs the key difference and a means which automatically corrects the key of accompaniment sound output from the player 1 based on the key difference and the device automatically corrects the key of the accompaniment sound reproduced by the player 1 by comparing the extract reproduced voice sound and the singing voice sound from the microphone 9 and by the operated key difference.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reproducing apparatus for singing a karaoke set in which a player reproduces a disk or a magnetic tape and sings while listening to an accompaniment sound.

[0002]

2. Description of the Related Art Conventionally, there has been a technique in which a disc player or a cassette tape player is provided with a karaoke function, and a singing voice input to a microphone and an accompaniment sound are mixed and reproduced.

[0003]

In the above-mentioned prior art, the means for manually adjusting the key (sound keynote) of the accompaniment sound output of the player was provided. However, the key of the accompaniment sound output corresponding to the key of the singer. Cannot be easily set, and the pitch of the accompaniment sound cannot be easily matched with the voice of the singer.

[0004]

According to the present invention, therefore, the means for extracting the singing voice output reproduced by the player is compared with the singing voice key input to the microphone and the singing voice output key from the player. And a means for automatically correcting the key of the accompaniment sound output from the player based on the difference between the keys and the reproduced singing voice sound to be extracted. Based on the key difference calculated by comparison with the singing voice from the microphone, the key of the accompaniment sound reproduced by the player is automatically corrected, so that an accompaniment sound whose pitch substantially matches that of the voice of the singer can be easily obtained. You can enjoy singing with the accompaniment sound of the key that suits the singer.

[0005]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block circuit diagram for karaoke, which is equipped with an audio player (1) for playing a video disc, a compact disc, or a cassette tape.
Through an accompaniment sound output circuit (2) for outputting an accompaniment sound (karaoke melody part) generated by playing a musical instrument and a singing sound output circuit (3) for outputting a singing voice sound (vocal part) by a singer, an audio player (1) The reproduced signals of the accompaniment sound and the singing voice sound are input to the digital signal conversion circuit (4).

The accompaniment sound and singing voice output converted into digital signals by the digital signal converting circuit (4) are input to the key control circuit (5), and the accompaniment sound and singing voice sound from the key control circuit (5) are input. The output is input to the analog signal demodulation circuit (6), and the accompaniment sound and singing voice output that are returned to the analog signal by the demodulation circuit (6) are input to the voice output circuit (7). At the same time, or only the accompaniment sound is reproduced and output by the speaker (8).

Further, a microphone (9) is connected to the voice output circuit (7), and a singing voice input to the microphone (9) is reproduced and output from the speaker (8) via the voice output circuit (7). It is configured to perform karaoke.

Further, a key data extraction circuit (10) which is means for extracting the singing voice output reproduced by the player (1) is provided, and the key data extraction circuit (10) is used to pass the bandpass filter (11) and the digital signal conversion circuit (12). The singing voice sound of the singing voice output circuit (3) is input to the extraction circuit (10) to detect the accompaniment sound and the key of the singing voice (keynote of the sound) reproduced by the player (1), and at the same time, a digital signal conversion circuit. The singing voice output of the microphone (9) is taken out to the key data extraction circuit (14) via (13), and the extraction circuit (14) detects the key of the singing voice input to the microphone (9). is doing.

Then, a key data comparison circuit (means for comparing the key of the singing voice input to the microphone (9) with the key of the singing voice output from the player (1) and outputting the difference between the keys ( 15) equipped with a microphone (9)
The comparison circuit (15) compares the key of the singing voice input to the key and the key of the singing voice output from the player (1) to calculate the difference between the keys, and the accompaniment sound from the player (1). The key control circuit (5), which is a means for automatically correcting the output key, inputs the key difference calculated by the comparison circuit (15), and outputs accompaniment sound and singing sound from the player (1). Key of the player (1) is automatically corrected by the key control circuit (5) based on the difference between the keys input from the comparison circuit (15), and is used as the key of the singing voice input to the microphone (9). The accompaniment sound output keys are made to substantially coincide with each other, and the accompaniment sound of the key matching the key of the singing voice is reproduced from the speaker (8).

This embodiment is configured as described above, and by reproducing the video disk (LD) or the like by the player (1) and singing by using the microphone (9), as shown in the flowchart of FIG. , The accompaniment sound and singing voice output from the player (1) are input to the key control circuit (5), and the singing voice output key of the player (1) and the singing voice key input to the microphone (9) The difference is input from the comparison circuit (15) to the key control circuit (5). When the singing voice key input to the microphone (9) is lower than the singing voice output key of the player (1), the player ( When the key of the singing voice input to the microphone (9) is higher than the key of the accompaniment sound output of 1) and the key of the singing voice output of the player (1) is higher than the key of the player (1), Raise the key of the accompaniment sound output of, the accompaniment sound you change the key in accordance with the people of key singing is intended to be reproduced from the speaker (8).

Further, a timer (not shown) for limiting the automatic correction time of the key control circuit (5) based on the output of the key data comparison circuit (15) is provided so that only the beginning portion of the music reproduced by the player (1) is described above. The key control operation is performed, and after the automatic correction time, the music can be played with the pitch fixed by the corrected predetermined key, and the time limit by the timer is released, and the key can be played from the beginning to the end of the music. It is also possible to continuously perform automatic correction of the key control circuit (5) based on the output of the data comparison circuit (15).

[0012]

As is apparent from the above embodiments, the present invention provides means for extracting a singing voice output reproduced by the player (1), keys for singing voice input to the microphone (9), and the player (1). ), A means for comparing the singing voice output key from the player) to output the key difference, and a means for automatically correcting the accompaniment sound output key from the player (1) based on the key difference. In this case, since the key of the accompaniment sound reproduced by the player (1) is automatically corrected based on the key difference calculated by comparing the reproduced singing voice sound to be extracted and the singing voice from the microphone (9), the voice of the singer On the other hand, an accompaniment sound having substantially the same pitch can be easily obtained, and the key accompaniment sound suitable for the singer can be enjoyed to sing.
