In the sound reproducing device according to the present invention configured as described above, the first signal processing unit 21 is used.
By executing a predetermined operation described later, a scoring function, an automatic registration function of a favorite song, and a preferential treatment function for advanced players are realized.

The scoring function of this sound reproducing apparatus is that the first signal processing unit 21 is outputting a music signal by the reproducing section 1 based on the integrated value (ΣΔPt) of the pitch difference information (music signal This is realized by controlling the reproducing unit 1 during reproduction. Further, the first signal processing unit 21 uses the integrated value (ΣΔP) of the pitch difference information.
Depending on t), different display is performed by the OSD display circuit 18 and the sound effect generation circuit 22.

Further, in this sound reproducing apparatus, the first signal processing unit 21 determines whether or not to continue the output of the music signal by the reproducing section 1 according to the integrated value (ΣΔPt) of the pitch difference information. If it is decided that the output of the music signal is to be ended and the output of the music signal is ended, the OSD display circuit 18 and the sound effect generation circuit 22 integrate the pitch difference information. Different display is performed according to the value (ΣΔPt).

In the automatic registration function of the favorite music, after the first signal processing unit 21 finishes outputting the music signal for one music by the reproducing unit 1, the integrated value of the pitch difference information ( ΣΔPt) is less than or equal to a predetermined value, the data related to the song is recorded in the personal information card 39.
It is realized by storing.

Further, as the preferential treatment function for advanced users, the first signal processing unit 21 ends the integrated value (ΣΔPt) of the pitch difference information after the first signal processing unit 21 finishes outputting the music signal for one music piece. ) Is less than or equal to a predetermined value,
This is realized by stopping the subtraction of the prepaid for the music or by adding the prepaid balance.

That is, the first signal processing unit 2
As shown in FIGS. 3 and 4, 1 starts operation in step st1 when this sound reproducing device is operated,
Go to step st2.

In the step st2, the first signal processing unit 21 determines whether or not the output of the music signal (reproduction of the music signal) by the reproduction section 1 is started. If the reproduction unit 1 has started the output of the music signal, the process proceeds to step st3. If the output of the music signal has not been started, the process proceeds to step st3.
Stay at 2.

The first signal processing unit 21 initializes the difference calculation timer (timer (1)) in step st3, and proceeds to step st4. The difference calculation timer defines a cycle of processing for detecting a difference between the ideal pitch information Prt and the singing pitch information Pit, and is set inside the first signal processing unit 21. .

In step st4, the first signal processing unit 21 initializes the singer's point Gt, sets it as P0 (Gt = P0), and proceeds to step st5. In this sound reproducing device, since the scoring is performed by the deduction method, P0 is a perfect score, for example, 100 points.

In step st5, the first signal processing unit 21 refers to the initial value of the ideal pitch information Prt, and proceeds to step st6.

The coefficient selecting timer is set inside the first signal processing unit 21, and performs addition processing in a forward calculation formula after initialization regardless of the operation of the first signal processing unit 21. .

When the ideal pitch information Prt changes,
That is, when the melody progresses and a transition is made to a sound with a different pitch, uncertainty increases in the pitch of the singer. In this sound reproducing device, in order to mitigate the influence of the uncertainty of the pitch at the time of pitch transition on the scoring evaluation, the pitch difference information (| Pit-Prt |) is a pitch difference information ΔP.
The coefficient value α for converting to t is selected from the two kinds of coefficient values α1 and α2 using the coefficient selecting timer. That is, in this sound reproducing device, as shown in FIG. 6, before the predetermined time set by the coefficient selecting timer elapses from the start of any one sound (N ₁ , N ₂ , N ₃ ...). In, a coefficient value α2 smaller than the coefficient value α1 is used. In this sound reproducing device, the coefficient value α2 is set after the lapse of a predetermined time set by the coefficient selection timer from the start of any one sound (N ₁ , N ₂ , N ₃ ...). A larger coefficient value α1 is used.

In step st8, the first signal processing unit 21 determines whether or not the reproduction of the music signal has been completed. If the reproduction of the music signal is completed, the process proceeds to step st23 of FIG. 4 (via (A) in FIGS. 3 and 4), and if the reproduction of the music signal is not completed, the process proceeds to step st9. move on.

In step st9, the first signal processing unit 21 determines whether or not the difference calculation timer (timer (1)) has overflowed. If the difference calculation timer has overflowed, the process proceeds to step st10, and if the difference calculation timer has not overflowed, the process returns to step st8.

The first signal processing unit 21 initializes the difference calculation timer in step st10, and proceeds to step st11.

By the way, the first signal processing unit 2
1 is each note (N ₁ ,
At the start of (N ₂ , N ₃ ...) (That is, the changing point of the ideal pitch information Prt), interrupt processing is executed as shown in FIG. 7.

In this interrupt processing, when the interrupt processing is started in step st36, the first signal processing unit 21 proceeds to step st37, inputs the ideal pitch information Prt, and proceeds to step st.
Proceed to 38. In step st38, the ideal pitch timer is initialized, and the process proceeds to step st39.
In step st39, the coefficient selecting timer is initialized, and the process proceeds to step st40 to end the interrupt process.

Then, the first signal processing unit 21
Determines in step st11 whether the coefficient selection timer has overflowed. If the coefficient selection timer has overflowed, the process proceeds to step st12, and if the coefficient selection timer has not overflowed, the process proceeds to step st13.

In the step st12, the first signal processing unit 21 sets α1 as the coefficient value α.
Is set, and the process proceeds to step st14. The first signal processing unit 21 sets α2 as the coefficient value α in step st13, and proceeds to step st14.

The first signal processing unit 21 calculates the pitch difference information (point deduction) ΔPt in step st14, and proceeds to step st15. As described above, this calculation is based on the above (first expression) (ΔPt = α |
Pit-Prt |). The coefficient value α used here is α2 or α1, and α2 ≦ α1. Also, at this time, so-called rounding processing is performed on the difference value (| Pit-Prt |) in order to reduce the influence of the intentional pitch variation of the singer for singing expression such as vibrato on the scoring evaluation. .

In the step st15, the first signal processing unit 21 calculates the holding point Gt,

In step st27, the first signal processing unit 21 determines whether or not the scoring result is higher than any of the scores in the score list ((PP-MP4)), and exceeds the score. In this case, the lowest song name in the score list is deleted, a new song name for which scoring is finished is added to the score list, and the process proceeds to step st28.
In addition, in this step st27, the first signal processing unit 21 described above makes the score list ((PP-MP
4)) according to the content of the above-mentioned favorite song list ((PP-M
0)) is updated and recorded in the personal information card 39.

In step st28, the first signal processing unit 21 determines whether or not the scoring result is better than a predetermined preferential score, for example, 90 points. If the scoring result is better than the preferential score, step s
When the scoring result is not better than the preferential treatment score, the process proceeds to t29, and the process proceeds to step st30.

In step st29, the first signal processing unit 21 adds a predetermined value to the prepaid balance or maintains the prepaid balance as it is (see FIG. 4 and (C) in FIG.
Return to step st2 in FIG. 3).

Further, the first signal processing unit 21
In step st30, the prepaid balance is subtracted from the prepaid balance by a predetermined value according to the duration of reproduction of the music signal or the number of music pieces (via (C) in FIGS. 4 and 3). ) Return to step st2 in FIG.

Incidentally, the above-mentioned first in this sound reproducing apparatus is used.
In the operation of the signal processing unit 21, the following interrupt processing shown in FIG. 5 may be performed at any time in place of the above-described interrupt processing shown in FIG.

In this interruption processing, when the interruption processing is started in step st31, the signal processing unit 21 proceeds to step st32 and determines whether or not the ideal pitch information Prt is a change point.
If the ideal pitch information Prt is a change point, step s
When the ideal pitch information Prt is not the change point, the process proceeds to t33, and the process proceeds to step st34. Then, the signal processing unit 21 initializes the coefficient selection timer in step st33, proceeds to step st35, and ends this interrupt processing. In addition, the signal processing unit 21 adds 1 to the coefficient selecting timer in the step st34, and executes the step st.
In step 35, the interrupt processing is terminated (in this case, it is assumed that the coefficient selection timer is subjected to addition processing according to the operation of the first signal processing unit 21).
