Abstract

PROBLEM TO BE SOLVED: To simplify the inputting operation of the transposition and tempo change of a melody incoming call sound. SOLUTION: When a request for tempo change/transposition is issued, the melody data are read from the prescribed region of a memory, and transferred to a working region (S1-S3). When the tempo change is selected (S4), and the tempo change data are inputted (S5, S6), melody data in the working region are changed in a batch according to the tempo change data (S7). In the same way, when the transposition is selected (S4), and the transposition data are inputted (S11, S12), the melody data in the working region are changed in a batch according to the transposition data (S13). After the melody data are changed, the presence or absence of confirmation is inquired to a user (S18), and when the confirmation is selected, the melody data in the working region are reproduced (S9). When the tempo change/transposition processing is ended, and OK is inputted (S10), the melody data in the working region of the memory are transferred to a normal region (S14), and a series of processing is ended.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal device such as a portable radio telephone, and more particularly, to a technique for changing a melody sound when a call is received.

[0002]

2. Description of the Related Art At present, cellular systems, PCS (Pers
onal Communication System) system, etc.
In mobile radio telephones that have become widespread, the shift to digital systems has made use of large-scale digital LSI technology, which has led to smaller and lighter devices.
Portability is getting better and better. In addition, advances in low power consumption technology and the adoption of lithium ion batteries have dramatically increased battery life. In addition, with the development of base stations, telephone calls can be made anywhere. As a result of this improved convenience, the number of registered subscribers nationwide has grown to over 30 million.

By the way, in a situation where everybody has a portable radio telephone, a request comes to have an original ring tone individually. For example, if there is an incoming call on someone's mobile phone in a situation where there are many people, there is a problem that the incoming call is mistaken for a ring tone for his or her own mobile wireless phone. For this reason, the conventional portable radio telephone has a configuration in which a number of popular songs are registered as ringtones in a dedicated IC, and the user can freely select and set the tunes. However, this configuration cannot cope with a situation in which it is desired to change a song due to the end of fashion. In addition, since a dedicated IC must be mounted, this is a factor of cost increase.

[0004] Therefore, recently, portable radio telephones equipped with an original ring tone creation function that allows a user to create and store a tune by freely setting a sound have become widespread. In addition, in order to omit a complicated music input operation, a service of receiving and inputting original ringtone data from a service center of a business or a communication partner via a wireless line has been provided. In addition, the hardware of the telephone has been improved, and the reproduction range has been widened. If the memory of the melody ringtone is increased, for example, it is possible to store all songs in a song. When this happens, it ’s not just the ringtone feature,
It can be used for the purpose of listening to music, and furthermore, it can be used in a so-called karaoke style, such as singing a song along with a reproduced song.

In the conventional method of creating an original ring tone, the user inputs the scale of the note data and the tempo of the sound (the length of the note) one by one by selecting a key. Such an operation is a considerable amount of work.
Here, if it is used for listening to music, karaoke, etc., it is necessary to change the transposition and the tempo, but since these settings all require the same work for each note, it is quite considerable for the user. It becomes burdensome. In particular, since the tempo is changed according to the length of the note, there is a disadvantage that fine adjustment cannot be performed.

Although the above description has been given of the case of a portable radio telephone, the same problem has been caused in other mobile communication terminal devices such as a PHS.

[0007]

As described above, in the conventional mobile communication terminal device, the input operation of the melody ringtone is a method of setting for each note. This must be set for each note, which requires a large amount of work and puts a considerable burden on the user.

[0023]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a configuration of a portable radio telephone as an example of a mobile communication terminal device according to the present invention. A QPSK-modulated radio frequency signal transmitted from a base station (not shown) via a digital communication channel. Is received by the antenna 1 and then input to the receiving circuit (RX) 3 via the antenna duplexer (DIU) 2. The receiving circuit 3 mixes the radio frequency signal with a receiving local oscillation signal generated from a frequency synthesizer circuit (SYN) 4 to convert the frequency into an intermediate frequency signal, and then amplifies and quadrature demodulates.
Note that the frequency of the reception local oscillation signal generated from the frequency synthesizer circuit 4 is not shown, but the control circuit (C
(ONT) 29.

The received intermediate frequency signal is converted into a digital signal by an A / D converter (AD) 6 and then input to a digital modulation / demodulation circuit (MODEM) 8. The digital modulation / demodulation circuit 8 performs delay detection of the received intermediate frequency signal, and further performs digital demodulation by establishing frame synchronization and detecting a color code signal to convert the signal into a digital baseband signal.

The digital baseband signal output from the digital modulation / demodulation circuit 8 includes a digital communication signal and a digital control signal. Among them, the digital control signal is taken into the control circuit 23 and identified. on the other hand,
The digital speech signal is sent to an error correction code decoding circuit (CH-C
ODEC: channel codec) 9. This error correction code decoding circuit 9 is a digital modulation / demodulation circuit 8
The digital communication signal supplied from the above is subjected to deinterleaving and error correction decoding processing. The error corrected and decoded digital communication signal is input to a speech codec (SP-CODEC: speech codec) 10. If the digital call signal is character information or melody information, it is input to the control circuit 29.

The voice codec 10 applies a VSELP (Vector Sum Excited L)
inear Prediction) or PSI-CELP (Pitch Sy)
nchronous innovation-Code Excited Linear Predict
ion), and performs audio decoding (DEC).
The speech signal output from the speech codec 10 is D
After being converted into an analog communication signal by the / A converter (DA) 11, the signal is amplified by the receiving amplifier 13 and output from the speaker 15.

On the other hand, the speaker's transmission signal collected by the microphone 16 and subjected to sound-electric conversion is amplified by the transmission amplifier 14 and then converted into a digital transmission signal by the A / D converter (AD) 12. The signal is converted and input to the speech codec 10. The voice codec 10 performs a voice coding process (CO
The digital transmission signal output from the audio codec 10 is input to the error correction codec 9 together with the digital control signal output from the control circuit 29. The error correction code decoding circuit 9 converts the digital transmission signal and the digital control signal into a digital baseband signal by performing an error correction coding process and an interleave process on the digital transmission signal and the digital control signal. The signal is input to the digital modulation / demodulation circuit 8. When character information and melody information are sent from the control circuit 29, they are processed as digital transmission signals.

The digital modulation / demodulation circuit 8 adds a frame signal and a color code signal to the digital baseband signal from the error correction code decoding circuit 9, further performs signal mapping processing, and then transmits the signal. The output of the digital modulation / demodulation circuit 8 is converted into an analog signal by a D / A converter (DA) 7 and input to a transmission circuit (TX) 5. This transmission circuit 5
Is used for orthogonally modulating a baseband signal converted to an analog signal, mixing with a transmission local oscillation signal generated by a synthesizer circuit 4, converting the signal to a predetermined transmission frequency, and amplifying the signal. The signal is transmitted to the antenna 1 via the antenna 2, and is transmitted from the antenna 1 as a radio wave to the base station.

The digital modulation / demodulation circuit 8, error correction code decoding circuit 9, and speech code decoding circuit 10 are connected to a bus line 28. The bus line 28 is a parallel signal line and controls an interface of various circuit units. The bus line 28 includes a control circuit 29 and a CPU 2.
3, ROM 24 and RAM 25 are connected.

The control circuit 29 controls each circuit connected to the bus line 28 based on a clock signal from a built-in oscillation circuit, and controls the LCD driving device 21.
The display control of the LCD display 22 is performed through the control unit, and the operation input processing of the key unit (KEY) 20 is performed.
The clock signal serves as a reference for the pitch and tempo of the melody.

Here, the LCD display 22 displays a telephone number and other states of the mobile phone. The key unit 20 includes numeric keys and function keys, and when a user performs an input operation of these keys, information such as a telephone number, a call, an end call, a character, a code, and a function setting is taken in.

The control circuit 29 controls a tone generator (GNE) 17 for generating a ring tone and a melody tone, and the tone output is amplified by a sounder amplifier 18.
The sound is output from the sounder 19. The speaker amplifier 18 also receives the speaker's voice signal output from the transmission amplifier 14 via the switch 30 and mixes it with the tone output from the tone generator 17.

On the other hand, the ROM 24 is constituted by a flash ROM or an EEPROM, and stores in advance various programs of the portable radio telephone, character information, melody information, an individual number, adjustment information of the radio, and the like. used. The CPU 23 fetches and executes a corresponding program from the ROM 24 in accordance with an instruction from the control circuit 29. The RAM 25 is composed of, for example, a flash memory, and has a backup battery (not shown) to retain stored information even when the device is not turned on. While storing the converted recording signal,
It is used to store character information and melody information input by the user.

Each of the above circuit blocks includes a battery 27.
Is stabilized by the stabilized power supply circuit 26 and supplied as power.

FIG. 2 is a block diagram showing a detailed configuration of the tone generator 17. In FIG. 2, the melody control unit 1
When receiving a melody reproduction command from the control circuit 29, the 01 fetches designated melody data from the RAM 25 via the bus line 28, and outputs a control signal to each section based on the data.

On the other hand, a reference clock signal (19.2 MHz) is supplied from the control circuit 29 to the pitch control unit 102 and the tempo control unit 103. The pitch control unit 102 divides the frequency of the clock signal based on the pitch data from the melody control unit 101 to generate a frequency signal corresponding to a desired pitch. The tempo control section 103 divides the clock signal by the tempo data from the melody control section 101 to generate a reference signal of a desired tempo. The reference signal is supplied to the tone length control section 104.

The tone length control section 104 is a melody control section 1
The tone length signal is generated by adjusting the timing of the reference signal based on the tone length data from 01. The frequency signal output from the pitch control unit 102 and the frequency signal output from the pitch control unit 104 and the pitch signal are supplied to a pitch / duration synthesis unit 105. The pitch / duration synthesizing unit 105 generates a melody signal by cutting out the frequency signal from the pitch control unit 102 at the timing of the pitch signal from the pitch control unit 104, and generates the melody signal. Is supplied to the volume control unit 106.

This volume control section 106 is a melody control section 1
The volume of the melody signal is adjusted based on the volume data from 01. Here, since the sounder 19 to be used is of an electromagnetic narrow band, the reception level correction is performed so that each pitch becomes flat in order to flatten the frequency characteristic and obtain a natural melody sound.

That is, as shown in FIG. 3, the frequency characteristic of a general sounder 19 has a characteristic having a resonance frequency of 2.33 [KHz]. Therefore, the lowest frequency 293.66 [Hz] showing the minimum sound pressure level is set to 0 [dB], and the difference from the sound level at each frequency is given. Thereby, the frequency characteristics of the sounder 19 can be corrected to flat characteristics. In the case of Fig. 3, the required attenuation at the resonance frequency is 18 [dB].

The volume of the melody signal output from volume control section 106 is adjusted by volume circuit 107 in accordance with a volume setting value given by a user operation.
The melody signal whose volume has been adjusted by the volume circuit 107 is amplified by a sounder amplifier 18 and then amplified by a sounder 19.
More loudspeaker output.

Next, the contents of the melody data will be specifically described.

The melody data for one tune is composed of data of each note constituting the melody and data indicating the end of the tune. The data of one note is the duration data (1Byt
e), pitch data (2 bytes: actually 11 bits) and volume data (1 byte). It is assumed that the data indicating the end of the music is note data having a note length data of 00H.

The pitch data can be set to a value from 000H to 7FFH. In this case, the reproduction frequency for the pitch data value can be calculated by the formula: reproduction frequency = 600000 / ((pitch data value) +1) [Hz]. However, 00H is a rest. FIG. 4 shows the relationship between the pitch data and the frequency to be reproduced.

As shown in FIG. 5, the note length data can be set in accordance with the note. 88H indicates a triplet, and 00H indicates the end of the music.

The volume correction data can be set to a value from 00H to FFH. In the volume correction, the volume correction data value of the frequency with the lowest sound pressure is set to FFH, and the volume correction data value is set so that the frequency and the sound pressure of the frequency to be corrected are equal. Assuming that the volume when the volume correction data value is FFH is the basic volume, the attenuation from the basic volume for an arbitrary volume correction data value is (attenuation) = 20 * log ((volume correction data value) / 255) [ dB]. 00H indicates silence data. FIG. 6 shows the relationship between the sound volume correction data value and the attenuation.

The note length is obtained by multiplying the basic note length determined by the tempo setting by the note length data value. The tempo setting value can be set in 31 steps from 01H to 1FH (00
H is prohibited). FIG. 7 shows the relationship between the tempo setting value and the actual note length.

The setting of the volume circuit 107 performs level control in accordance with the volume operation of the user. FIG. 8 shows the relationship between the volume set value by the volume and the amount of attenuation from the basic volume.

Next, the operation of changing the original ring tone according to the present embodiment will be described with reference to the flowchart shown in FIG.

First, in the standby state, the original ring tone (the ring tone for downloading may be used) is stored in the RAM 25.
Is stored in a predetermined area. In this state, when a tempo change / transposition of the original ring tone is requested by a user's key input operation, a tempo change / transposition program is loaded from the ROM 24 and executed by the CPU 23.

FIG. 9 shows the processing contents of the tempo change / transposition program. First, a screen showing a procedure for selecting an original ring tone in response to a tempo change / transposition request is displayed (S1). When the user selects a ringtone according to the contents displayed on the screen (S2), the corresponding melody data is read from a predetermined area of the RAM 25 and moved to a work area (S3).

Next, a message asking whether the tempo should be changed or transposed is displayed (S4). Here, when the tempo change is selected, a tempo change data input screen is displayed (S5),
It waits for data input (S6). The tempo change data is
For example, a step value such as 10% (in this case, using the cursor key), a numerical input such as ♪ = 120 (in this case, using the numeric keypad), and the like can be considered.

If there is a data input, the melody data in the work area of the RAM 25 is changed collectively according to the tempo change data (S7). At this time, an inquiry screen asking whether to confirm with the user is displayed (S8), and if confirmation is selected, the melody data in the work area is reproduced (S9). After playback (or during playback), a screen asking whether the content is OK is displayed (S9). If OK is not selected, the process returns to step S4 to prompt resetting.

On the other hand, if transposition is selected in step S4, a transposition data input screen is displayed (S11), and data input is awaited (S12). In addition to inputting transposition data in semitone steps, it is also conceivable to directly input the pitch of the first note (for example, to specify “レ” for the sound of “do”). When the transposition data is input, the melody data in the work area of the RAM 25 is collectively changed according to the transposition data (S13), and the process proceeds to step S8.

When the tempo change / transposition processing is completed and OK is input in step S10, the RAM 25
The melody data in the work area is moved to the regular area (S14), and a series of processing is ended.

In the above description, the case where the entire melody is changed collectively is described. However, an arbitrary range can be changed collectively by providing a step of specifying a range.

FIG. 10 shows an example of the melody data before the change. This tune is composed of eight eighth notes.
The pitch is one octave of D4 to D5. Also,
The tempo is ♪ = 240 ms, and the tempo setting data at this time is 0CH. The tempo can be changed in the middle of a song, but here it is assumed that the tempo is the same for one song. In this example, if it is assumed that the tempo is increased by about 10% by the user setting and the transposition is made semitone higher, the data is converted into the data shown in FIG. At this time, the tempo ♪ = 220 ms, and the setting data is changed to 0BH. Further, the scale setting data and the volume correction data are all changed. This changing method will be described below.

FIG. 12 shows the correspondence between the scale setting data necessary for the conversion and the volume correction data. This correspondence is
It is stored in a predetermined area of the RAM 25 in advance. C
The PU 23 generates melody scale data and volume correction data using the table values and sets the data in the tone generator 17 for generating a melody, thereby generating a desired melody. What is actually stored as melody data on the RAM 25 is a software (SW) code, which has a value of 1 to 36 and covers a range of three octaves. Here, the value is shown as a decimal value for easy understanding, but is calculated as a hexadecimal value on a program.

The RAM 25 stores in advance the scale data set values and volume correction data set values corresponding to the codes 1 to 36. If the user's transposition setting request is a setting for raising a semitone, all + 1's are added to the chord value of the music and converted to a new chord. By storing all the data set values and volume correction values and converting them all, there is an advantage that the amount of memory can be reduced.

When the change to the new music is completed, the sound of the new music can be output from the sounder 19 to confirm whether the new music is the desired music. If the user listens to the song and is OK, the melody data in the regular area is rewritten and the process is completed. If the user is dissatisfied with the viewing result, the user can request a correction and reset it.

By applying the above functions, it is possible to enjoy the karaoke practice function, that is, to reproduce the pitch and tempo as desired, and to record and reproduce the sound in accordance with it. The operation of the recording process in this case will be described with reference to FIG.

For example, a karaoke function selection instruction is assigned to a function key in advance, and when a user operates the key, a karaoke program is stored in a ROM.
24 to be executed by the CPU 23. At this time, the CPU 23 displays the melody candidate and allows the user to select a tune. When a song is selected, the melody data
After reading from the AM 25 and, if necessary, changing the tempo and transposing by the above-described processing, the tone generator 17 reproduces the melody and the sounder 19 outputs the loudspeaker.

The user's voice and the reproduced sound from the sounder 19 are collected by the microphone 16 and converted into an electric signal, then amplified to a desired level by the transmission amplifier 14, and converted into a digital signal by the A / D converter 12. , And stored as recording data in a predetermined area of the RAM 25 via the audio codec 10 and the bus line 28. In the case of reproduction, the data is converted into an analog audio signal by the D / A converter 11 from the RAM 25 via the bus line 28 and the audio codec 10 in accordance with a reproduction key selection operation by the user.
, And is reproduced from the speaker 15. If this karaoke reproduction process is executed during communication, the other party can hear a melody with a user voice input.

As described above, according to the present embodiment,
A correspondence table of pitch, frequency setting code, and volume correction code is created, and the soft code of the pitch is collectively converted according to the transposition data request, and updated to the desired frequency setting code and volume correction code. It is possible to change the tempo by changing the tempo data which is the basis of the tone length, so that the user can perform transposition and change the tempo by a simple operation. Further, even when the ring tone is downloaded from the base station, the same procedure is possible.

In the description of the above embodiment, the case of transposition processing in which the pitch is simply raised or lowered in semitone steps has been described. If a key change table is prepared, such as changing the key, these changes can be handled by a simple operation. These changing processes are particularly effective when chord output is possible.

Further, it goes without saying that the present invention can be applied not only to the above-mentioned radio telephone but also to other mobile communication terminals.

[0067]

As described above, according to the present invention, even when a similar input operation is required for each note, such as transposition of a melody ringtone or a change in tempo, the input operation can be easily performed. A mobile communication terminal device capable of performing the above-described operations can be provided.
