DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a karaoke apparatus, and more particularly to a karaoke apparatus that allows for diversification of karaoke usage.

[Prior Art] Conventionally, in karaoke machines installed in ordinary homes, restaurants, etc., audio information input by a singer into a microphone is input into an amplifier together with musical tone information from a compact disc (CD), etc., for mixing and processing. Generally, the signal is amplified and output from a speaker.

[Problems to be Solved by the Invention] However, the above-mentioned conventional device simply outputs audio information input manually from the microphone.
Multiple singers are always required to perform a chorus such as a round or duet, and there has been a lack of diversification in how karaoke can be used by a single singer.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a karaoke device that allows even human singers to enjoy choral singing using their own voices, thereby diversifying karaoke usage. That is.

[Means for Solving the Problems] The present invention provides a karaoke apparatus in which musical tone information from a musical tone information storage medium and voice information from a voice input means are reproduced by a reproduction means. a voice storage means for storing information; and a reproduction means for controlling the storage of the voice information to be stored in the voice storage means, and reproducing the voice information stored during reproduction of the musical tone information with a predetermined delay time. The invention is characterized in that it is provided with a control means for controlling the transfer.

[Function] The function of the karaoke apparatus according to the present invention having the above configuration is as follows.

When audio information corresponding to musical tone information is input to the audio input means, the control means performs control to transfer and store the input audio information to the audio storage means.

Furthermore, the control means transfers the audio information stored in the audio storage means to the continuously operating reproduction means with a predetermined delay time.

As a result, the voice information currently being input into the voice input means,
Previously input audio information from the storage means is output from the reproduction means in a superimposed state together with musical tone information.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The karaoke apparatus shown in FIG.
A storage means 4 as a musical tone information storage medium that separately stores musical tone information of a large number of songs (N songs) connected to 3 in the form of digital information, and a voice that is analog information when a singer inputs voice. a microphone 5 as a voice input means for transmitting information; a reproduction means 6 for reproducing voice information from the microphone 5 and musical tone information from the storage means 4 transmitted under the control of the control means 2; It has a memory 7 as a voice storage means for capturing and storing voice information from the microphone 5 under the control of the control means 2.

The control means 2 includes the CPU 3, an A/D conversion section 8 that converts the audio information from the microphone 5 into digital audio information, and converts the digital audio information from the storage means 4 or the memory 7 into analog audio information. It is equipped with a D/A converter 9 that converts into audio information, and a timer 0 that performs a timekeeping operation under the control of the CPU 3.

That is, the CPU 3 performs storage control for sending the digital audio information from the A/D converter 8 to the memory 7 to be stored therein, and performs readout control from the memory 7. Also, this CP
U3 controls sending digital musical tone information from the storage means 4 or digital audio information read from the memory 7 to the reproduction means 6 via the D/A converter 9.

The reproduction means 6 includes an amplifier 11 that mixes reproduction information from the D/A converter 9 and musical tone information from the microphone 5, amplifies and outputs the mixture, and a speaker 2 that outputs the output signal from the amplifier 11 as sound. It is equipped with.

Further, an input section 13 connected to the CPU 3 is provided, and the selection of music and the chorus mode can be made by operating keys on the input section 13, for example.

Each musical tone information stored in the storage means 4 has an information structure as shown in FIG.

That is, each piece of musical tone information from the 1st to the Nth song includes predetermined delay time data (for example, data indicating the time from the time when the first lyric of each stroke starts until the time when round singing begins) and each song. It also includes performance data corresponding to the melody.

The delay time data is read out by the CPU 3 together with the performance data, and is used for managing the set time of the timer 10.

Next, the operation of the karaoke apparatus 1 will be explained.

First, a music selection and a chorus mode are designated by key operations on the input section 13. When the karaoke device 1 starts operating, the CPU 3 outputs specified musical tone information for the first song, for example.
That is, the delay time data and performance data of the first song are read from the storage means 4, and the performance data thereof is sent to the D/A converter 9.

The D/A converter 9 converts the performance data into analog musical tone information and sends it to the amplifier 11.

Thereby, the musical tone information is amplified by the amplifier 11 and then outputted by the speaker 12, and the performance of the first song begins.

When this performance reaches the start of the first song and the singer inputs audio corresponding to the lyrics from the microphone 5, the audio information is sent from the microphone 5 to the amplifier 11, and the performance and audio are output from the speaker 12. be done.

On the other hand, when the singer starts singing, the timer 10 starts operating under the control of the CPU 3 which has taken in the delay time data, and at the same time, the audio information from the microphone 5 is converted into digital audio information by the A/D converter 8. After being converted into , it is stored in the memory 7 under the control of the CPU 3.

The CPU 3 reads the audio information stored in the memory 7 and transfers it to the D/A converter 9 when the set time of the timer 10 based on the delay time data has elapsed. The D/A converter 9 sends the transferred audio information to the amplifier 11 as analog audio information.

On the other hand, in this state, the D/A converter 9 transfers musical tone information corresponding to, for example, the second measure of the first song of the first song to the amplifier 11.
The singer is inputting the audio of the lyrics corresponding to the second measure from the microphone 5.

In addition, by outputting the audio of the first bar that has already been sung from the speaker 12, the second bar that the singer is currently singing can be
The first measure of the song sung in the past can be played following the song of the measure, and thereafter, the song sung in the past can be played with a delay of one measure, making it possible to perform a ring sing-along by a single singer.

Note that the chorus mode that can be realized by once recording the audio input from the microphone 5 and reproducing and outputting it with a predetermined delay time is not limited to the above-mentioned round singing, but also a duet and the like. The method of round singing is not limited to double round singing, but it is also possible to obtain triple, quadruple, and even multiple round singing effects by controlling the readout of audio information.

Also, depending on the song, there are some songs that can be sung in a round or a duet, and some that are not. In order to make it impossible to select the chorus mode for a song that cannot be choral-singed, it is also possible to register bit information indicating that choral-singing is not possible, for example, in the storage area of delay time data in the musical tone information.

In addition to the embodiments described above, the present invention can be modified in various ways within the scope of its gist.

In the above-described embodiment, the musical tone information includes a delay time tab, but it is also possible to provide a table on the CPUB side in which one-point data indicating the read timing of audio information from the memory 7 is stored according to famous pieces. For example, the musical tone information stored in the storage means 4 can be only performance data, and in this case, existing performance software can be used as is to realize a chorus by a single singer.

Moreover, by storing the point data in advance in this way, the timer 10 of the karaoke apparatus 1 can be omitted, and the configuration can be simplified.

[Effects of the Invention] According to the present invention described in detail above, the audio information from the audio input means is temporarily stored in the audio storage means, and after a predetermined delay time, is transferred to the reproducing means during the reproducing operation and reproduced. As a result, even people with disabilities can enjoy chorus singing, and the ways to use karaoke can be diversified.
