〔Example〕

Examples of the present invention will be described below with reference to FIG. 1.2. FIG. 1 is a schematic circuit diagram showing an embodiment of a singing ability evaluation device to which the display device of the present invention is applied;
FIG. 1 is a flowchart for explaining the display operation of the display device shown in FIG.

In FIG. 1, the singing ability evaluation device 1 roughly consists of an evaluation circuit 2 equipped with a microphone input terminal 2m and tape input terminals 2N and 2r for left and right channels, and a display device 3 that displays the evaluation results of the evaluation circuit 2. configured.

The microphone input terminal 2m of the evaluation circuit 2 is connected to the RAM 7 via a microphone amplifier circuit 4, a low-pass filter circuit 5 with a filtering band of about 300 Hz, and a waveform shaping circuit 6. The left channel tape input terminal 21 is connected to the tape amplifier circuit 8.
It is connected to the RAM 7 via a low-pass filter circuit 9 whose filtering band is an audible band and a waveform shaping circuit 10 . The tape input terminal 2r of the right channel is connected to the RAM 7 via a preamplifier circuit 11, a tape amplifier circuit 2, a low-pass filter circuit 13 whose filtering band is the audible band, and a waveform shaping circuit 14.

The reason why the filtering band of the low-pass filter circuit 5 that low-pass filters the microphone input is narrower than the others is that the fundamental pitch frequency of the singer's voice can be sufficiently identified using audio information up to about 300 Hz. .

Further, each waveform shaping circuit 6.10.14 shapes the analog signal waveform into a digital signal waveform by amplifying the input signal and then clipping the portion below a predetermined darkness value.

The RAM 7 stores the microphone input and two tape inputs supplied via the three waveform shaping circuits 6, 10, and 14 as digital data, and exchanges data with the ROM 15. The ROM 15 is connected to a central processing unit 19 by a data bus 17 and an address bus 18 via a latch circuit 16.
The data read from the ROM 15 is processed according to a predetermined processing procedure, and the data for driving the display device 3 is sent back to the ROM 15.

Data for driving the display device 3 sent to the ROM 15 is supplied to the drive circuits 20 and 21 for driving the display device 3 and the audio synthesis circuit 22 via the RAM 7. The speech synthesis circuit 22 synthesizes necessary instructions, cautions, etc. into speech.

On the other hand, the display device 3 includes an overall score display section 23 that can display numbers from 0 to 199, and a display section 24 that displays evaluations mainly in the treble range, bass range, and rhythm in five levels.
It consists of 25.26. While the overall score display section 23 has a configuration using three number display elements 23a in which seven light emitting elements are arranged in an 8-shape, the other three display sections 24.2
5.26 has a matrix structure in which five light emitting elements 27 are arranged in a horizontal line to form three stages: top, middle, and bottom.

Each number display element 23a of the overall score display section 23 is time-divisionally driven by the drive circuit 20, and is connected to other display sections 24, 25.
．． The 26 light emitting elements 27 are time-divisionally driven by the drive circuit 20 for each column, and time-divisionally driven by the drive circuit 21 for each row. Further, the drive circuit 21 drives each common side of the three number display elements 23a.

A tape recorder (not shown) that plays back a music tape used for karaoke accompaniment inputs accompaniment and model singing to the left and right channel tape input terminals 21.2r, respectively.

Further, in this embodiment, the display sections 24 and 26 correspond to a pitch display section and a rhythm display section, respectively.

Next, the operation of the display device 3 will be explained with reference to FIG. 2.

First, when the power of the singing ability evaluation device 1 is turned on, the step (101) shown in FIG.
In step 02), the on/off status of the scoring switch (not shown) is checked, and if it is on, the random bar shown in step (103) is displayed, and if it is off, the step (103) is displayed.
The non-display state shown in 104) is taken. The random bar display is made by display parts 24, 25, and 26 consisting of five light-emitting elements 27 in the upper, middle, and lower rows repeating random flashing, and the display is a light evoking the rhythm of clapping or clapping. You can see the flashing.

Next, when the accompaniment music starts playing, it is determined in step (105) that there is a tape input for the left channel, and then in step (106), the middle display section 25 blinks in time with the prelude before singing begins. do. Then, in the following step (107), it is checked again whether the scoring switch is on, and if it is on,
In the next step (108), a determination is made whether there is a right channel tape input.

When the tape input of the right channel, that is, the model singing voice that is the standard for scoring, is input, the system enters the scoring mode. This scoring is done not only on the overall score but also on the sound deviation and sense of rhythm in the high and low ranges, but while singing, as shown in step (109), the upper display section 24 shows the accompaniment. The progress of the singing is displayed, and the lower display section 26 displays the progress of the singing.

In other words, the pitch changes in the high range of the tape input of the right channel and the pitch changes of the microphone input are displayed on the display sections 24 and 2, respectively.
6, the display device 3 functions as a singing guide. Therefore, if a person has a poor sense of rhythm,
The displays on the display sections 24 and 26 are not aligned and exhibit blinking changes that are unrelated to each other.

Step (110) following step (109) is a step to detect the end of the song recorded on the tape, and if it is determined that there is no left and right tape input for more than 3 seconds, the next step is to detect the end of the song recorded on the tape. In step (111), it is checked whether the data obtained so far is sufficient for scoring evaluation. At this time, if it is a data foot, the X display blinks and a sound indicating a data foot is generated as shown in step (112), and the process returns to step (103). Also, if sufficient data is available,
The process moves to a step (113) of erasing all the display. In this step (113), the melody corresponding to the scoring result is generated by the voice synthesis circuit 22, as in the past, which indicates the data
is synthesized by

When one second has passed since this melody is generated, the judgment is made in step (114), and then step (115) is performed.
Shift to random display of scores. This random display is performed on the overall score display section 23 and the other three display sections 24.
25 and 26 display random scores and have the effect of heightening the tension before the score announcement.

When this random display continues for 4 seconds, step (11)
After the judgment in step 6), the scoring result display shown in step (117) is reached. As for the overall scoring result, the score out of 100 is displayed on the display section 23, and the treble range scoring result, the low range scoring result, and the rhythm scoring result are displayed on other display sections 24, 25, and 26, respectively. Displayed in 5 stages. In the illustrated example, it is displayed that the treble range, bass range, and rhythm received an evaluation of 4.5.4 out of a total score of 88 points.

In this way, after the scoring results are displayed in step (117), the same display continues until the playback button (not shown) on the tape recorder is pressed, at which point the display proceeds to step (118). Step (103)
) will return to the random bar display.

In this way, while the singer is singing, the display device 3 displays changes in each pitch of the accompaniment and singing on the display sections 24 and 26, which evaluate and display the singer's singing ability in stages with respect to the pitch and rhythm of a specific range. Because of the structure, it not only has a scoring display function that simply displays the score for singing with accompaniment, but also visually informs the singer of the match or mismatch between the rhythm of the accompaniment and the song, making it easier for singers who lack a sense of rhythm to sing. As a guide, you can help improve your singing ability.
In particular, it can be provided with additional functions that are useful as a scoring machine for karaoke performances.

〔Effect of the invention〕

As explained above, according to the present invention, while the singer is singing, the pitch display section and the rhythm display section, which evaluate and display the singer's singing ability in stages with respect to the pitch and rhythm of a specific range, are displayed. Since it is configured to display pitch changes, it not only has a scoring display function that simply displays the score for singing with accompaniment, but also visually informs the singer of the match or mismatch between the rhythm of the accompaniment and the song, so there is no lack of rhythm confusion. It can be used as a singing guide for singers who want to improve their singing ability, and it has excellent effects such as being able to have additional functions that are especially useful as a scoring machine for karaoke performances.
