．． In this embodiment, the display body 12 is a 7-segment digital numeric display. This is also used as a numeric display to display other numerical data.For example, recently some performance devices have been equipped with a grading function for grading how well and how poorly they sing. The numeric display is not used during performance, so you can use it.

It has the above configuration, and its operation will be explained below.

First, when a pack containing the audio multiplex recording medium 1 is attached to a performance apparatus, the magnetic head 21 is brought into contact with the first track 2, and the magnetic head 23 is brought into contact with the second track 3, respectively. When the performance starts, the vocal signal of the first track 2 is converted into an electric signal by the magnetic head 21, amplified by the amplifier 22, and supplied to the second amplification means 7 through the volume 27.

At the same time, the music signal of the second track 3 is converted into an electric signal by the magnetic head 23, amplified by the amplifier 24, and supplied to the second amplifying means 7 through the volume 28. Second
The amplifying means 7 amplifies the signals supplied from the first reproducing means 4 and the second reproducing means 5 to drive the speaker 8.

The user listens to the music and vocals amplified from the speaker 8 and sings along with the music into the microphone 26.

The signal from the microphone 25 is amplified by an amplifier 26 and supplied to the second amplifying means 7 via a volume. As a result, the vocal signal of the first track 2, the music signal of the second track 3, and the song sung by the user are mixed and amplified from the speaker 8. The mixing amount of these sounds can be adjusted with the volume 27, 28, and 29, so the level at which the vocal signal is amplified from the speaker 8 can be changed according to the user's level of proficiency, allowing for sufficient singing practice. . When the user has mastered the song, it is possible to prevent the vocal signal from being amplified from the speaker 8 at all.

However, when singing the singer's vocal signal recorded on the first track without amplifying it from speaker 8, depending on the song, even if you are familiar with the song, you may get the length of the intro wrong and stumble at the beginning of the song. . In order to eliminate such inconveniences, the performance device of the present invention is configured to visually display the starting position of a song, and to enable the user to recognize whether or not he or she has actually started singing at the correct starting position. The operation of the song start position display mechanism will be explained below using the flowcharts of FIGS. 3 and 4.

First, when a performance is started, no vocal signal is recorded on the first track 2 during the intro portion of the song, and no signal is output from the magnetic head 21. Therefore, no signal is supplied from the first reproducing means 4 to the first rectifying circuit 31 and the second amplifying means 7. Then, only the music signal recorded on the second track 3 is reproduced by the second reproduction means, amplified by the second amplification means 7, and amplified from the speaker 8.

Next, when the intro part of the song ends and the beginning part of the song comes, since the vocal signal is recorded on the first track 2, this signal is reproduced by 1 degree by the first reproducing means 4 and the first rectifying circuit 31. is supplied to the microcomputer 35 after being waveform-shaped by the first waveform shaping circuit 32.
supplied to The display body 12 is driven by the signal supplied to the microcomputer 36.

Also, if the user sings into the microphone 26,
The user's audio signal is amplified by the first amplification means 6 and the second
is supplied to the rectifier circuit 33, waveform-shaped by the second waveform shaping circuit 34, and supplied to the microcomputer 35,
Driving the Display 12 The above operation will be explained using the flowchart of FIG. 4. First, in step 41, it is determined whether or not there is a vocal signal on the first track 2. Here, if there is a vocal signal, the process proceeds to step 42; if not, the process proceeds to step 63.

Now that the intro of the song has finished and the vocal signal at the beginning of the song is being played, proceed to step 42.
Then, it is determined whether or not there is a microphone signal from the first amplifying means 6. If the user has already started singing at the beginning of the song, the process advances to step 43, where the microcomputer 36 instructs the display 12 to display 1" in the third digit of the numeric counter on the display 12, and if the user is still singing. If it has not started yet, the process proceeds to step 44, where the microcomputer 36 instructs the display 12 so that the third digit of the numeric display of the display 12 displays °°O''.

Next, the process proceeds to step 46, where it is determined whether there is any further vocal signal. Since the vocal signal is currently being reproduced, the process advances to step 46, and it is determined whether or not there is a microphone signal. If the user is singing, step 47
The microcomputer 35 causes the display unit 12 to display ``1'' as the second digit instead of ``1'' or ``0°'' in the third digit. 12
If the user is not singing, the process proceeds to step 48, and the third digit of the numeric counter on the display 12 displays ``1'' or ``0°'' instead of the second digit ``0°°''. A command is issued from the microcomputer 36 to the display body 12.

Next, the process further advances to step 4e, and it is determined whether or not there is a vocal signal. Since the vocal signal continues to be reproduced, the process proceeds to step 60, where it is determined whether or not there is a microphone signal.

If the user is singing, the process advances to step 51, where the microcomputer 35 instructs the display 12 to display the second digit 1'' or "1" on the numeric display of the display 12. If not, the process proceeds to step 62, where the microcomputer 35 causes the display 12 to display ○'' as the first digit instead of 1' or ○'' as the second digit on the numeric display of the display 12. command to.

Similarly, while the vocal signal is being played back, the steps are as follows: step 41 → step 42 → step 43 or step 44 → step 46 → step 46 → step 47 or step 48 → step 49 → step 6o → step 61 or step Repeat the action 52.

Therefore, while the vocal signal is being played back, the numeric display on the foot 12 will display "1°" or °○.
The movement of "°" from the 3rd digit to the 2nd digit and from the 2nd digit to the 1st digit is repeated, and since the vocal signal is being played back, the user can easily tell that it is the singing position. .

Therefore, the user only has to start singing in accordance with the display on the display 12, and if the starting position of the vocal signal and the user's starting position match, the third digit of the numeric display on the display 12 The initial display will be "1'°," and conversely, if the starting position of the vocal signal and the user's starting position do not match, the first display of the third digit on the numeric display of the display unit 12 will be "60". Therefore, the user can recognize that he or she has started singing at the correct starting position. Note that when the vocal signal is interrupted, such as between each bar of a song, it is determined in each of steps 41, 46, and 49 that there is no vocal signal, and the process does not proceed to step 63, and it is determined whether or not there is a microphone signal. , if there is a microphone signal, the third digit of the numeric display of the display unit 12 is displayed in step 64.
0°° will be displayed, indicating that there is no vocal signal, only a microphone signal. Also, step 53
If there is no microphone signal, proceed to step 66;
The display of the numeric display on the display body 12 is stopped, and the process returns to step 9 41 where the display is turned off.

Then, when the next measure starts and the vocal signal is reproduced again, the display 12 is driven.

As described above, according to this embodiment, since the vocal signal is detected at the beginning of the song and the display 12 is displayed, it is possible to eliminate the delay in the start of the song by the user, and even at the beginning of a measure in the middle of the song. By displaying on the display 12, it is possible to eliminate delays in the user's start of singing, and it is also possible to recognize whether or not the user has actually started singing late, and the tempo of the user's singing does not match the vocal signal. Even if the user is singing when there is no vocal signal, this can be recognized.

In this embodiment, the numeric display of the display body 12 displays 1°" or "O", but any other combination of digits or any of the seven numeric display segments 16 - and decimal point segments may be used. It may be lit in combination.

Further, in this embodiment, a numeric display for other uses is shared, but a dedicated display body may be used, such as arranging a plurality of light emitting diodes. FIG. 5 shows various examples of driving the display body.
