Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a karaoke device that is used for singers to sing along with songs output from speakers.

[Prior art 1] Conventionally, in a karaoke apparatus, when a karaoke user does not clearly remember the content of the song he or she wishes to play, he or she may want to confirm the content of the song in preparation for selecting a song. In such cases, you may want to check the content of the song by actually playing it. In this case, the operation of searching for a single song to check the content of the song from all stored songs is as follows. It is done like this.

When the karaoke user enters the designated song number of the song he/she wants to check the content of, the karaoke machine's built-in central control device (
The microcomputer reads the designated song number and selects a compact disc (CD) or video disc (VD) (hereinafter simply referred to as a disc) according to the designated song number.A karaoke machine has multiple discs set. , a single disk stores performance data for a large number of songs.The performance data for each song includes an individual song number.The ROM of the central control unit contains:
A database is stored in which song numbers and disc numbers are associated with each other.

Therefore, the central control unit searches the database according to the input specified song number, finds a disk number from the song number corresponding to the specified song number, selects the disk corresponding to the disk number from a large group of disks, The disk is loaded onto the rotary disk by a loading mechanism. Next, the reading head, which moves in the radial direction of the rotary disk, is moved to a position on the disk where performance data of a song corresponding to the designated song number is stored.

Then, the disk is rotated together with the turntable, the performance data is read out, and the performance is performed.

The operation of such a central control unit is exactly the same as when a singer actually performs a song.

The karaoke user listens to the played song and confirms whether it is the song he/she wants to sing. If it is not the desired song, the user stops playing that song and inputs another specified song number. The central control unit performs the designated song again in the same manner as described above. If the specified song number is the same as the previous specified song number, you can leave the disc on the rotary disk, but if it is different, unload the previous disc into the storage compartment and insert another disc. will be loaded onto the rotary disk again.

[Problems to be Solved by the Invention] However, although the purpose is only to confirm the content of a song, the operation of loading the disc whose content is to be confirmed onto the rotary disk using a loading mechanism; Since it is necessary to perform a series of mechanical operations such as rotating the turntable and often necessary unloading of the disc, a considerable amount of time must be spent performing operations for retrieving song contents. There wasn't.

Particularly, nowadays, karaoke has become widespread in people's lives, regardless of age or gender, and the number of discs is increasing accordingly.

Therefore, the reality is that it takes a considerable amount of time to search among a large group of disks for the disk that stores the performance data of the song whose contents are to be confirmed.

[Object of the Invention] The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to shorten the time required for searching for confirmation of song contents.

[Means for Solving the Problems] In order to achieve this object, the karaoke device of the present invention has the following features:

The hard disk 3 stores retrieval performance data D1, which is part of the total performance data, for each famous piece of all stored music.

As the search performance data D1, data of a characteristic part of the famous piece of music is adopted from among all the performance data of the famous piece of music. In other words, the data is such that even if it is only a part of a song, the content of the song can be easily determined by listening to the performance of the song.

The search performance data D1 on the hard disk 3 is transferred to the central control device 2.

This hard disk 3 corresponds to the retrieval performance data storage means M1 in the configuration of the invention.

The singing performance data storage section 4 stores all the performance data D3 for each famous song for all the stored songs. The performance data D3 is also transferred to the central control device 2.

The central control device 2 reads performance data D1 for search of the corresponding song from the hard disk 3 according to the search music designation data D2 input from the switch panel 1, and also reads performance data D1 for performance music input from the switch panel 1. Accordingly, the performance data D3 of the corresponding song is read from the singing performance data storage section 4, and the search performance data D1 or the performance data D3 is transferred to the music reproduction device W5. The central control device 2 is the control means M in the configuration of the invention.
Corresponds to 3.

The music playback device 5 converts the search performance data D1 or the performance data D3 into an analog performance audio signal S.

The configuration is such that the signal is converted into a signal and output to the mixing amplifier 6. The singer's microphone 7 is connected to the mixing amplifier 6.
The mixing amplifier 6 mixes and amplifies the performance audio signal S and the singing audio signal S2, and outputs the synthesized audio signal S3 to the speaker 8. It is supposed to be done.

The music reproduction device 5, the mixing amplifier 6, the microphone 7, and the speaker 8 correspond to the performance means M4 in the configuration of the invention.

FIG. 3 conceptually shows the structure of the singing performance data storage section 4. As shown in FIG.

A plurality of discs 9 are set in a disc storage section 10. Each disk 9 stores all the performance data D3 of each of a large number of songs. The loading mechanism 11 is configured to take out one of the plurality of disks 9, which stores a song specified by the performance song specification data D4, from the disk storage section 10 and transfer it onto the rotary disk 12. has been done. The performance data D3 on the disk 9 on the rotary disk 12 is read by a reading head 13 and transferred to the central control device 2.

The hard disk 3 stores search performance data D1, which is part of all the performance data D3 for all songs stored on the plurality of disks 9. While the singing performance data storage section 4 is a collection of a plurality of disks 9, the hard disk 3
is a single storage device.

Next, the operation of this karaoke device will be explained.

If the karaoke user (singer) does not remember the content of the song he is about to sing and wants to check the content of the song before singing, he presses the search mode key 1b on the switch panel 1. Then, input the song number to be confirmed using the song number maximum key 1a.

If you find the song you want to output by checking the song content, or if you know the song content from the beginning and there is no need to search for the song, press the performance key lc and then press the song number to output the performance. is input using the largest song number 1a.

The central control device 2 executes processing according to the flowchart shown in FIG.

In step S1, it is determined whether the search mode key 1b has been pressed, and if it has not been pressed, the process advances to step S2 to determine whether the performance key 1c has been pressed, and if it has not been pressed, the process returns to step S1. .

When it is determined in step S1 that the search mode key 1b has been pressed, the process proceeds to step S3, sets a flag F indicating that the search mode has been selected, and waits for the highest song number key 1a to be pressed in step S4. Then, the search song designation data D2 input in step S5 is stored.

Next, in step S6, the hard disk 3 is searched based on the search song designation data D2, and the search performance data D1 of the song having the song number corresponding to the search song designation data D2 is read out.

Since the hard disk 3 is a single storage device, both the search access and the read access of the search performance data D1 are directly performed. Furthermore, since the search performance data D1 is part of the performance data D3, high-speed access is possible.

Then, the search performance data D read out in step S7

If the song is not the desired song, the user presses the song number Hitokaki-1a again to designate another song, but if it is the desired song, the player presses the performance key 10.

The central control device 2 determines whether the performance key IC has been pressed in step S8, and if it has not been pressed, returns to step S4, and repeats steps 34 to S8 until the desired song is found.

When the desired song is found, press the play key IC in step s8.
If it is determined that the desired song has been pressed, or if the desired song is known from the beginning and the performance key 1c is pressed without pressing the search mode key lb, the performance key 1 is pressed in step S2.
If it is determined that c has been pressed, the process advances to step S9.

In step S9, it is determined whether flag F is set, and if it is not set, step SIO
The program advances to step S11, waits until the highest song number key 13 is pressed, and stores the performance song designation data D4 input in step Sll. When the flag F is set, the process advances to step S12, where the flag F is reset, and then the process proceeds to step S5.
At step 13, the search music designation data D2 stored at the previous step S5 is stored again as performance music designation data D4.

Then, in step S14, the loading mechanism 11 is driven based on the performance music designation data D4, and the disc 9 storing the performance data D3 of the designated music number is taken out from the disc storage section 10 and transferred to the turntable 12. Step S
The turntable 12 is rotated in step S15, and the turntable 1 is rotated in step S16.
The performance data D3 of the specified song number is read out from the disk 9 on the disk 9 on 2 through the reading head 13, and the performance data D3 read out in step S17 is transferred to the music playback device 5. Perform.

The music reproducing device 5 converts the performance≠-data D3 into an analog performance audio signal S1 and outputs it to the mixing amplifier 6.
