Next, a detailed configuration example of the music reproducing section 15 and the audio processing section 14 is shown in FIG.

First, the music reproducing section 15 will be described. In the figure, the interface (I / F) 30 is an interface for exchanging various data via the bus 24. In the initial setting of the music data performed before the music playback, the music data except for the tone data of the music data input through the I / F 30 is controlled by the write / read controller (R / W controller) 31, It is stored in an empty area of the music data storage (RAM) 32. The storage capacity of the RAM 32 is smaller than the storage capacity required for storing one piece of music data, and is, for example, a storage capacity capable of storing 32 words of music data. Therefore, the first 32 words of the music data are stored.

The tone data in the music data is supplied to and stored in the voice RAM (tone data storage) 36. The voice RAM 36 has a storage capacity capable of storing a plurality of timbre data of timbres. This timbre data consists of waveform parameters, envelope parameters, modulation parameters, effect parameters, and other parameters, and each parameter is a parameter unique to each timbre. The waveform parameter in each tone data indicates a sound wave waveform corresponding to the tone. For example, when the sound source unit 34 is a PCM sound source having a waveform table, the waveform parameter is a parameter indicating one waveform of the waveform table. When the sound source unit 34 is an FM sound source, the waveform parameter is a parameter instructing an algorithm of the FM operation. The envelope parameter is a parameter such as attack rate, attenuation rate, duration level, recovery rate, and the like. The modulation parameter is a parameter of depth or speed of vibrato or tremolo, and the effect parameter is a parameter such as reverb, chorus, and vibration.

In addition, according to the read request signal Req from the sequence 33, the sequencer 33 receives the tempo data read out from the RAM 32 by the R / W controller 31 and sets the tempo. In addition, the sequencer 33 analyzes the music data, assigns a voice number designated for each part to the voice RAM 36, reads a voice parameter corresponding to the voice number from the voice RAM 36, and sets it in the sound source unit 34. Doing.

When music reproduction starts, the R / W controller 31 reads out the music data from the RAM 32 in order according to the read request signal Req from the sequencer 33 and supplies it to the sequencer 33. The sequencer 33 receives the music data from the R / W controller 31 in order, analyzes the music data, and sets the sound source parameter corresponding to the music data to the sound source unit 34 so as to be pronounced at a predetermined pronunciation timing. . Sound source parameters include pitch data, note on / off signals, and the like.

The sound source unit 34 can simultaneously pronounce a sound signal of a plurality of parts of the left and right channels, and the sound of the sound signal of each part is set to a sound read from the voice RAM 36, and together with the sound, the sequencer 33 The sound data based on the sound source parameter supplied from the () is generated for each part. The generated plural parts amount of sound data is supplied to a digital-to-analog converter (DAC) 35 and converted into an analog sound signal.

When the read of the sound data from the RAM 32 progresses and a predetermined amount of free area is generated in the RAM 32, the R / W controller 31 sends the transfer request signal Req to the interface 30. It sends out to the bus 24 via the said. Upon receipt of this transfer request signal, the CPU 10 reads out subsequent music data from the RAM 11 for a predetermined amount, for example, 16 words corresponding to a free area, and sends it to the bus 24. This piece of music data is written into the free area of the RAM 32 under the control of the R / W controller 31 via the I / F 30. By repeating such an operation, the entire music can be reproduced even if the storage capacity of the RAM 32 is smaller than the storage capacity required for storing one piece of music data.

When the reproduced music is soundproofed, the coefficient of the coefficient multiplier 40 becomes "1", the audio signal representing the song input from the microphone 21 and the mixer 51 are synthesized, and the speaker 23 Soundproof When the output of the DAC 35 is used for the ring tone, the coefficient of the coefficient multiplier 54 becomes "0", and only the ring tone is soundproofed from the speaker 23. When the reproduced sound signal is used as the reserved sound, the coefficient of the coefficient multiplier 37 becomes "1" and is output from the sign language speaker 22 through the mixer 38. In this case, the coefficient of the coefficient multiplier 50 becomes "0", and the output of the DAC 49 is not supplied to the mixer 38. In this case, the musical sound signal output from the sound source unit 34 is supplied to the audio processing unit 14 as a pending sound signal for transmission.

Next, the audio processing unit 14 will be described. In the voice processing unit 14 shown in FIG. 3, in the case of a normal call, the voice signal input from the microphone 21 is converted into a digital signal by the analog-to-digital converter (ADC) 42 and the coefficient multiplier 43 It is supplied to the mixer 44 through. The mixer 44 is supplied with the music signal for BGM reproduced by the music reproducing unit 15 through the coefficient multiplier 45. The output of the mixer 44 is encoded by the encoder 46 and supplied to the communication unit 13.

In order to expand the multiple numbers of speech, the encoder 46 and the decoder 48 include high efficiency compression encoding / decoding using band compression technology, for example, ADPCM (Adaptive Differential PCM) or CELPC (Code Excited LPC). Is used. The signal input from the communication unit 13 is decoded by the decoder 48, and is also converted into an analog sign signal by the digital-to-analog converter (DAC) 49 and supplied to the music reproducing unit 15. On the other hand, when the key operation for designating the karaoke mode of the input unit 17 is performed, the coefficient of the coefficient multiplier 54 becomes "1", and the voice signal of the singer input from the microphone 21 causes the coefficient multiplier 54 to operate. It is supplied to the mixer 51 which is a synthesis means, and mixed with the regenerated karaoke music (accompaniment sound).

Next, the scoring parameter extraction part 25 is demonstrated with reference to FIG. First, the voice signal of the singer output from the microphone 21 (FIG. 3) and the reproduced sound signal (output of the DAC 35) are input to the preprocessor 61. The preprocessor 61 removes the high and low noises through the voice band filter and outputs the input voice signal as the voice signal of the singer. The preprocessor 61 extracts a sample of the vocal voice signal from the input sound signal. That is, in the case of the audio multiplexing system, accompaniment is recorded in the left channel signal, and samples of the accompaniment and singing voice are recorded in the right channel signal. There, the preprocessor 61 extracts the audio signal representing the sample of the song by subtracting the left channel signal from the right channel signal. Next, the extracted voice signal is passed through a voice band filter to remove high and low noise and output as a sample vocal voice signal.

The pitch extraction unit 62 first extracts a pitch from each of the singer voice signal and the sample vocal voice signal supplied from the preprocessor 61. As the pitch extraction method, a known zero crossing interval detection method, an autocorrelation method, a combination thereof, or the like can be used. Each speech signal from which the pitch is extracted is converted into pitch data after the vibrato component is removed by the low pass filter.

That is, the frequency f, which is the inverse of the extracted pitch, deviates from the fundamental frequency 32.7032 kHz and is represented by the following equation.

f = 32.7032 × 2 ^{(P + Q / 12)} [㎐] (1)

Where P is octave data and Q is chromatic data. Therefore, the pitch data is calculated based on the following equation.

P + (Q / 12) = log ₂ (f / 32.7032) (2)

In addition, the octave data P is an integer and it is determined so that the absolute value of Q may be minimum. This conversion to pitch data is because comparisons that match the auditory characteristics can be made. And the singer pitch data and the sample vocal pitch data obtained by the process mentioned above are output to the scoring part 64, respectively.

In addition, the volume extracting unit 63 generates the volume data by absoluteizing and smoothing the amplitude values of each of the input singer voice signal and the sample vocal voice signal, and uses the scoring unit as the singer volume data and the sample vocal volume data. 64).

The scoring unit 64 compares the input singer pitch data with the sample vocal pitch data on the basis of a comparison timing signal based on a constant period or a pitch extracted from the reproduced speech signal. The counter counts up when the two nearly match, and the coincidence degree of the pitch data is calculated from this count value. Similarly, the singer volume data and the sample vocal volume data are compared in synchronization with the above-described comparison timing signal, and if the two are almost identical, the counter counts up, and the coincidence of the volume data is calculated from this count value.

In addition, random numbers are generated to approach subjective evaluation as well as reproducible mechanical comparison processing. The coincidence of the pitch data, the coincidence of the volume data, and the random number are added after multiplying the pitch importance parameter?, The volume importance parameter?, And the random number focus parameter?. Each parameter (alpha), (beta), (gamma) is adjustable by arbitrary parameter ratio so that the parameter setting part 65 may satisfy (alpha) + (beta) + (gamma) = 1. This addition value is converted into scores and output to the display unit 18.

In addition, although the method of extracting and scoring the sample vocal audio signal from the music data with respect to the scoring parameter extraction part 25 was demonstrated, the music data may not include an audio signal and may only be accompaniment data. In this case, the scoring data parameters including the pitch data arranged in time series and the volume data are added and transmitted to the music data. In this case, the scoring parameter extraction unit 25 extracts the pitch data and the volume data from the singer voice signal and outputs them to the CPU 10. The CPU 10 performs scoring by comparing the input data with the scoring reference parameters.

Next, the operation of the system described above will be described. First, the operation of downloading the desired music data from the center 110 by the cellular phone 1 will be described. The telephone number of the center 110 is input by operating the key of the input unit 17 of the cellular phone 1, and the call button is turned on. By turning on the originating button, the CPU 10 activates the communication program stored in the ROM 12 to make a call. The outgoing signal to which the telephone number information of the cellular phone 1 is added is transmitted from the communication unit 13 to the base station 124c managing the radio zone to which the cellular phone 1 belongs via the antenna 1a. Base station 124c sends the received signal to mobile switching center 123. The mobile switching center 123 determines the telephone switching center 121a of the center 110 and sends a signal toward the path. An incoming signal is sent from the telephone exchange station 121a to the center 110, and the incoming button is operated to establish a line.

When the line is established, the mobile phone 1 sends a registration number, a music number to be transmitted, and the like. The registration number received by the center 110 is confirmed, and downloading of music data is started. The music data transmitted from the center 110 is received from the base station 124c via the telephone exchange station 121a, and is input to the communication unit 13 through the antenna 1a. The communication unit 13 outputs demodulated music data from the received radio signal. This piece of music data is stored in the RAM 11. The music data includes data for karaoke accompaniment (voice data, tempo data for determining the tempo to play back, tone assignment data for setting the tone of each part, one piece of note data or rest data), and sample vocal voice data. , Lyrics data, and graphic data for displaying a background image. When the download process ends, the line is disconnected and the outgoing process ends.

Next, the operation of the karaoke mode in which the music is reproduced from the music data stored in the RAM 11 and the singer inputs an audio signal from the microphone 21 will be described. First, when a user performs a key operation of selecting the karaoke mode of the input unit 17, and then inputs a desired music number from the input unit 17, and performs a key operation instructing to start playing, input from the input unit 17 is performed. By the music number thus obtained, the CPU 10 reads out music data stored in the RAM 11. The music data read out from the RAM 11 is input to the I / F 30 via the bus 24, and an initial setting process of the music data is executed.

In the initial setting process, music data excluding tone data from the I / F 30 is stored in the RAM 32. The timbre data output from the I / F 30 is stored in the voice RAM 36. The sequencer 33 interprets the tone allocation data, reads the tone parameters for each part from the voice RAM 36, sets them in the sound source unit 34, and sets tempo data in the sequencer 33. When the initial setting processing ends, reproduction of the music data starts, and the R / W controller 31 reads out the music data from the RAM 32 in order according to the read request signal Req from the sequencer 33, and thereby sequencer. It supplies to 33. The sound source unit 34 generates sound signals of multiple parts based on the sound source parameters from the music data input from the sequencer 33, mixes them with sample vocal sound data, and outputs them. The DAC 35 outputs the input sound data. It converts into analog sound signal by digital / analog conversion. This music signal is supplied to the mixer 51 through the coefficient multiplier 40.

On the other hand, the singer inputs a voice signal from the microphone 21. At this time, the coefficient of the coefficient multiplier 54 is "1", and the input audio signal is supplied to the mixer 51 and mixed with the reproduced sound signal. One of the mixed outputs is adjusted to a predetermined level by the coefficient multiplier 53 and soundproofed from the speaker 23. At this time, the CPU 10 sends the lyrics data and graphic data in the music data to the display unit 18 in synchronization with the music reproduction process. The other output of the mixer 51 is supplied to the FM transmitter 26 through the coefficient multiplier 52. The FM transmitter 26 transmits the FM modulated signal to an external FM receiver through the antenna 27. When the FM transmitter 26 is turned on, the coefficient of the coefficient multiplier 53 becomes "0", and the signal is not output from the speaker 23.

On the other hand, the scoring parameter extraction unit 25 receives the voice signal of the singer input from the microphone 21 through the voice processing unit 14 and the sound signal reproduced by the music reproducing unit 15. The scoring parameter extracting unit 25 extracts the singer pitch data and the singer volume data from the input voice signal, and extracts the sample vocal pitch data and the sample vocal volume data from the sound signal. And the pitch data of both voices are compared, and also the volume data of both voices are compared, and the score of a singer is computed from the agreement degree. The CPU 10 causes the display unit 18 to display the score calculated by the scoring parameter extraction unit 25 in combination with the timing of music reproduction.

Next, when the reproduction of the music is finished and the final scoring result is displayed on the display unit 18, the scoring result is sent to the center 110, and when recording is desired, the scoring data is transmitted from the input unit 17. Do the operation. The CPU 10 receives this operation and transmits a call signal of the center 110. After establishing the line with the center 110, the scoring data is transmitted together with the user number and music number. The center 110 confirms that the received user number is registered, and stores the scoring data and the music number in the internal storage device. Next, the current rank is obtained for the piece of music, and the obtained rank is stored in the storage device. 5 is a diagram illustrating a storage state of the user data described above. This stored scoring data or ranking data is sent from the center 110 to the user's mobile phone on a regular basis or when the user desires, and can be confirmed on the display unit 18 of the mobile phone.

In this manner, according to the above-described mobile phone system, the scoring data can be easily received from the center 110 at any time and anywhere without self-management. As a result, the degree of improvement can be checked at any time and at any time, and a legitimate, official and objective scoring result can be obtained, so that an objective ability can be known to others and can be proud of to others.

In addition, when a certificate or a premium is sent offline based on the weekly ranking and the monthly ranking, the pleasure increases and the desire to do so increases. Further, the download price of music data may be lowered based on the weekly ranking, monthly ranking, or the number of registrations of the scoring data.

As described above, according to the present invention, since the mobile phone is provided with a scoring function of the singing power, the scoring result can be sent to the management center for management through the communication network, so that the objective scoring results can be viewed at any time. Not only does it help to improve your singing skills, but it also adds to the joy of karaoke and can be used in the karaoke entertainment industry. In addition, according to the present invention, since the scoring result and the ranking information in the group can be transmitted from the management center at regular intervals, as a result of the effort for the practice of setting the goal goal, the scoring result can be effectively used. It can be used in the karaoke entertainment industry.
