Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone capable of generating a distinctive ringing tone. here,
In this specification, a mobile phone is used as a concept indicating both a so-called mobile phone known as a cellular system and a PHS phone in a simple mobile phone system.

[0002]

2. Description of the Related Art When a mobile phone receives an incoming call, a ring tone is emitted to notify the user of the incoming call. A conventional beep tone has been generally used as the ring tone. However, since the beep tone is unpleasant, a tone that can generate a melody tone as a ring tone instead of the beep tone has been put to practical use. This is a so-called ringtone melody.

Further, the circuit for generating the melody ringtone has also been improved, and it has become possible to generate a musical tone having a sound quality enough to withstand viewing from a conventional melody having a cheap sound quality.

[0004]

However, if the sound quality of the melody ring tone is improved, even if the melody ring tone is pronounced or recognized as automatic performance music,
Since it is a good sound, it is heard, and there is a disadvantage that the user may not notice that this is a ringtone.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a portable telephone capable of recognizing a good sound and a call by combining another ringing sound with a melody ringtone.

[0006]

SUMMARY OF THE INVENTION The present invention provides a plurality of sound signal generating means for generating different sound signals, and all or a part of the plurality of sound signal generating means when a call from another telephone is detected. And control means for sequentially switching (repeating) the operations.

As the acoustic signal generating means, for example, a beep sound generating means for generating a beep sound, a sound reproducing means for generating a pre-recorded sound, a music playing means for generating a musical tone based on music data, and the like are used. it can. By switching and operating all or part of these sound signal generating means and sequentially switching and outputting a plurality of kinds of sound signals, it is possible to generate a sound signal with a variety of characteristics. In this case, when the audio signals are switched using the cross fade, the audio signals can be smoothly switched.

In the present invention, as the plurality of sound signal generating means, a beep sound generating means for generating the above-mentioned beep sound, a sound reproducing means for reproducing a pre-recorded sound, and
Using a music playing means for generating a musical tone based on music data, operating a beep sound generating means or a sound reproducing means for a predetermined time, and then operating the music playing means. In this way, by using the music piece of the music piece playing means as the ring tone corresponding to the call, it is possible to notify the incoming call with a changing non-jarring tone. Furthermore, by using such a natural tone as a ring tone, sometimes the user does not notice that the call is an incoming call, but in such a case, a beep or voice is generated first. The user can be made aware of the incoming call. This can also be realized by configuring the plurality of sound signal generating means with music playing means generating a plurality of types of musical sounds.
That is, the music playing means generates a ring tone without a melody, for example, a bell sound or a beep sound, plays a tune with a melody, generates a ring tone without a melody first, and then plays the music. This can be realized by causing the means to play a tune having a melody.

Further, according to the present invention, a ringing tone generating means for generating a ringing tone for continuously hitting a metal bell, and when a ringing from another telephone is detected, the ringing tone generating means for about two seconds. Control means for repeatedly performing the operation in a cycle of stopping for about one second. By generating a sound for continuously hitting a metal bell for two seconds and stopping it for one second, a ringing tone similar to the bell sound of a conventional wired telephone can be generated. With such an acoustic bell sound, the degree of discomfort to surrounding people, such as the ringing tone of the current mobile phone, is reduced.

The input unit 24, the display unit 25, and the vibrator 26 are connected. The system CPU 10 controls the operation of each unit of the mobile phone 1 by executing a telephone function program, and has a built-in timer for indicating an elapsed time during operation or generating a timer interrupt at a specific time interval. I have. When receiving an interrupt request signal (IRQ) from the music playing section 15, the system CPU 10 executes a processing operation for assisting a music playing process described later. In the system RAM 11, a music data storage area for storing music data of a music piece played by the music performance unit 15, an audio data storage area for storing audio data to be reproduced by the recording and reproduction unit 16, and a setting data storage for storing user setting data. Areas are set. The music data is composed of musical score data and timbre data. The music data and audio data can be downloaded from the download center via the communication unit 13 and can be transferred from the external device 2 such as a personal computer via the interface 27. The user setting data storage area also includes a ring tone mode register for storing a ring tone mode. The system ROM 12 includes a system CPU 10
The program stores programs such as various telephone function programs for transmission and reception, processes for assisting music reproduction processing, and various data such as preset music data and audio data.

The communication section 13 demodulates a signal received by the antenna 1a, modulates a signal to be transmitted, and supplies the modulated signal to the antenna 1a. The reception signal demodulated by the communication unit 13 is decoded by a voice processing unit (coder / decoder) 14, and the transmission signal input from the microphone 28 is compression-coded by the voice processing unit 14. The audio processing unit 14
The voice for transmission is encoded / decoded with high efficiency and is, for example, a coder / decoder of a CELP (Code Excited LPC) system or an ADPCM (adaptive differential PCM coding) system. The reception signal demodulated by the voice processing unit 14 and the transmission signal input from the microphone 28 are
a, sound is emitted from the receiving speaker 23 via the mixer 22; Further, the audio processing unit 14 can also input a musical tone playing a musical composition from the musical musical performance unit 15, compress the encoded musical tone, and input the compression encoded to the communication unit 13.

The music playing section 15 is an LSI capable of playing a multi-tone music based on music data stored in the system RAM 11 or the system ROM 12. This LSI
Has a built-in sequencer that executes an automatic performance function and a sound source section that forms musical tone waveforms. By supplying music data, it can play various music pieces (including only musical sounds without melody). . This music performance part 15
Will be described later. The recording / reproducing unit 16 reproduces the recorded voice input from the microphone 22 and the voice data input from the system RAM 11 or the system ROM 12. As the voice data, words such as "phone", a voice of a waveform that is difficult to synthesize such as a dog cry, and the like are used. The beep sound generating unit 17 is an oscillation circuit that generates a ringing sound of a general “beep-beep ...” sound.

The tone generated by the music playing section 15, the voice reproduced by the recording / reproducing section 16, and the ringing tone generated by the beep generating section 17 are variable gain amplifiers 18 a, 18 b, 1, respectively.
The sound is emitted from the calling speaker 20 via the mixer 8 and the mixer 8. The musical tone generated by the music playing section 15 is
It is also output to the audio processing unit 14 and the variable gain amplifier 21b. The musical tone amplified by the variable gain amplifier 21b is emitted from the receiving speaker 23 via the mixer 22. The musical sounds generated by the music playing section 15 are ringtones (listening sounds,
Karaoke sound), hold sound, and BGM. When used as a ringtone, the variable gain amplifier 1
The tone is emitted from the calling speaker 20 by increasing the gain of 8a. When used as a holding tone or BGM, the gain of the variable gain amplifier 21b is increased so that the musical tone is emitted from the receiving speaker 23, and the musical tone is input to the audio processing unit to be reproduced. To be sent to the other party. When the musical tone is output as a hold tone, the gain of the microphone 28 is reduced to prevent the input signal of the microphone from being transmitted to the other party, and the gain of the variable gain amplifier 21a is also reduced to reduce the gain from the receiving speaker 23. This microphone sound is not output. On the other hand, when the tone is used as BGM, the microphone 28 and the gain of the variable gain amplifier 21a are set to the same level as in a normal call, and the microphone sound and the tone are transmitted to the other party together, and The output is made from the speaker 23.

The portable telephone 1 serves as a ring tone when a call is received from another telephone.
7 can be used, any of the sound generated by the recording / reproducing unit 16 and the sound generated by the music playing unit 15 can be used. The pattern of the ring tone includes a beep sound only, a voice only, a transition from a beep to a musical tone, a transition from a voice to a musical tone, and the like. The reason that the tone is not used as the ring tone is that the tone is an advanced sound quality used in addition to the ring tone, so that a beep or voice indicating that the tone is a ring tone is generated first, and then the tone is shifted to the tone. That's why. Which (which combination) is generated as a ring tone can be set by the user.

When a beep-like ringing tone is synthesized by the music playing section, the music-playing section only generates the beep-like ringing tone and then shifts to music data performance. It is also possible to generate a ringtone.

In this case, the ringing tone synthesized by the music playing section includes a bell sound such as "Riririri ..." which hits a metal bell used in a conventional wired telephone. The timbre of this bell sound is also set as timbre data in the timbre data storage unit 34.
It is composed of a combination of note data for generating this musical tone for two seconds and rest data for resting it for one second. By playing this, the ringing tone of a conventional telephone can be reproduced. When this is combined with a music having a normal melody, the timbre of the bell sound is added to one timbre and a part, and the bell sound is first performed in the above pattern, and then the melody having the melody is added. The music score data may be described so as to perform

An interface (I / F) 27 is an interface for connecting to an external device 2 such as a personal computer, from which the music data and audio data are transferred. The input unit 24 is the mobile phone 1
And dial buttons from "0" to "9" and various function buttons. The display unit 25 displays a menu corresponding to a telephone function and a display corresponding to an operation of a button such as a dial button. The vibrator 26 is a vibrator for notifying a user of an incoming call by vibrating the main body of the mobile phone 1 instead of a ring tone at the time of an incoming call.

FIG. 2 shows an example of the configuration of the music playing section 15. In FIG. 2, an interface 30 is an interface for receiving various data via a bus 29. The interface 30 includes various data including musical score data and tone color data, and index data (INDEX) indicating what data the received data is. Separately, data is output from the DATA output, and index data (INDEX) is IND
Output from EX output. FIFO (First-In First-
Out) 31 is a storage means capable of storing, for example, 32 words of musical score data, and is sequentially read from the previously written musical score data. When the musical score data is sequentially read from the FIFO 31 and a free area of a predetermined amount (IRQ point) is generated, the FIFO 31 sends an interrupt request signal (IRQ) to the system CPU 10.

The INDEX decoder 32 decodes the index data and outputs a write pulse (WP) to an I / D signal to be described later.
RQ point data latch pulse (LP) is FIFO
When data received by the sequencer 33 is output from the DATA output of the interface 30, index data AD 1 indicating the fact is supplied to the sequencer 33, and a tone color data storage unit (Voice RAM) 34
The tone data received by the
When outputting from the output, the tone data storage unit 34 is supplied with index data AD2 indicating that fact. The sequencer 33 sends a write pulse (Read) to the FIFO 31.
The musical score data is sequentially read out from the FIFO 31 by applying the tone data, and the tone generation parameter corresponding to the musical score data is set in the tone generator 35 in accordance with the time information in the musical score data. Further, the timbre number of each part specified by the timbre assignment data taken from the DATA output of the interface 30 is supplied to the timbre data storage unit 34, and the timbre parameter corresponding to the timbre number is read out from the timbre data storage unit 34. Each part of the sound source section 35 is set.

The timbre data storage section 34 is storage means for storing timbre data taken from the DATA output of the interface 30 and has a small storage capacity for storing, for example, timbre data for eight tones. The sound source unit 35
For example, tone signals of four parts can be generated simultaneously, and each part is set to the tone read from the tone data storage unit 34 in accordance with the tone color assignment data.
A tone signal having a pitch and a sounding time length in accordance with the sounding parameters supplied from 3 is generated for each part. The generated tone signals for the four parts are supplied to a digital-to-analog converter (DAC) 36 at each predetermined reproduction timing, and become analog tone signals. Analog tone signals are output to the variable gain amplifiers 18a and 21b. A digital tone signal that does not pass through the DAC 36 is input to the audio processing unit 14.

When the mobile phone 1 is set to the music selection mode, the user can operate the input unit 24 and the display unit 25 to select music to be played by the music performance unit 15. In the music data of the music selected by the user, the first part (sound color data and music data for 32 words) is stored in the system RAM 1.
1 or is read from the system ROM 12 and set in the music playing section 15 in advance.

In the music playing section 15, the INDEX decoder 32 decodes the index data attached to the timbre data from the timbre data of the eight timbres in the music data taken in via the interface 30, and stores the timbre data in the timbre data storage section. By supplying the tone data 34 to the tone color data storage unit 34 as index data AD2.
The timbre data written in the timbre data storage unit 34 can be selected from a large number of timbre data stored in the system RAM 11 and transferred. FIG. 4 shows a configuration example of the tone color data for eight tone colors written in the tone color data storage unit 34.

As shown in FIG. 4, the timbre data of timbres 1 to 8 are composed of waveform parameters, envelope parameters, modulation parameters, and effect parameters, each of which is a parameter unique to timbres 1 to 8. It has been. The waveform parameter in each timbre data indicates a musical tone waveform.
Is a parameter indicating one of the waveforms in the waveform table when the sound source is a PCM sound source having a waveform table.
It is a parameter that indicates the algorithm of the M operation.
Envelope parameters are parameters such as attack rate, decay rate, sustain level, and release rate, modulation parameters are parameters for vibrato and tremolo depth and speed, and effect parameters are parameters for reverb, chorus, variation, and the like. .

The tempo data (Tempo) and the timbre assignment data in the music data fetched via the interface 30 are the index data attached to the tempo data and the timbre assignment data.
Decodes the index data A into the sequencer 33.
By supplying it as D1, it is taken into the sequencer 33. The sequencer 33 stores the timbre parameters specified by the fetched timbre assignment data in the timbre data storage unit 34.
And set it in the sound source unit 35. FIG. 5 shows a configuration example of the tone color assignment data at this time. As shown in FIG.
The timbres assigned to Part 1 and Part 4 are indicated by timbre numbers. That is, when the sequencer 33 supplies the timbre number specified for each part to the timbre data storage means 34, the timbre parameters corresponding to the timbre number are read out from the timbre data storage means 34 and transmitted to the tone generator 35 as the timbre of each part. Each will be set.

Since the timbre data for the music data to be reproduced is transferred and written to the timbre data storage unit 34, the desired timbre data is selected from the system RAM 11 and written into the timbre data storage unit 34. Music of various timbres can be reproduced. The tone color assignment data and tempo can be edited by the user.

Further, the musical score data in the music data taken in through the interface 30 is obtained by converting the index data attached to the musical score data into the INDEX decoder 3.
2 decodes and supplies a write pulse (WP) to the FIFO 31, so that the musical score data for 32 words is written into the FIFO 31. The 32 words are music score data of a part of one music piece, and are set as the first music score data.

The musical score data written in the FIFO 31 is composed of note data and rest data, and an example of the data configuration is shown in FIG. The one-word note data shown in FIG. 3 includes an octave code, a note code, a part number to which the note data belongs, an interval that is a time length until the next note or rest, and a note length information. The one-word rest data shown in FIG. 3 is composed of rest data indicating the type of rest, the part number to which the rest data belongs, and an interval that is the time length until the next note or rest. Have been.

A call signal from another telephone is transmitted to the communication unit 1
3 or the user has a music on hold, BG
When a musical performance is instructed by M, karaoke sound, or the like, the musical performance set in the musical performance section 15 is started.

Here, when a start instruction for reproducing music data is input to the music reproducing unit 15, the sequencer 33 applies a read pulse (Read) to the FIFO 31 and
The musical score data is sequentially read out from the IFO 31, and if the musical score data is note data, the pitch data of the octave code and the note code in the musical score data, the part designation information, and the key-on at timing based on the set tempo information and interval information. Is set in the sound source unit 35. The tone generator 35 generates a tone having a designated pitch based on the tone color parameters set for the designated part from the data set in the tone generator register. Then, at the timing when the note length of the note data has elapsed, the sequencer 33 sets the key-off data of the musical tone in the tone generator 35 by designating the part. Thereby, the sound source unit 35 performs a silencing process of the musical sound. Such processing is executed each time the musical score data is read out from the FIFO 31, so that the tone signal reproduced from the sound source section 35 is output to the audio processing section 14 and the DAC 36, and is converted into an analog signal by the DAC 36. The generated tone signal is output to the amplifiers 18a and 21b.

As described above, the above-mentioned note data and rest data are sequentially read from the FIFO 31, and an empty area is generated in the FIFO 31 by the read amount. Since only the first 32 words of the musical score data are written in the FIFO 31, the next musical score data following the generated empty area is stored in the system RAM1.
1 is read and newly written. As a result, a high-quality musical sound with a large amount of data can be played. FIF
The number of empty areas in O31 when the next musical score data is written into FIFO 31, ie, when an empty area in many words occurs, an interrupt request signal (I
RQ) to be input to the system CPU 10 is set in advance.

When the empty area detected in the FIFO 31 becomes equal to the IRQ point data value with the progress of tone reproduction, an interrupt request signal (IRQ) is given to the system CPU 10. In response to this, the system CPU 10 reads the next score data from the system RAM 11 by (31-IRQ points) words and
To send to. This musical score data is written to an empty area of the FIFO 31 via the interface 30. By repeatedly executing such a process of writing the next musical score data for (31-IRQ point) words to the FIFO 31, even if the musical score data is composed of a large amount of data, all the data are eventually stored in the FIFO 31. Is written. The musical score data read out from the FIFO 31 is reproduced and output in accordance with the tempo in the tone generator 35, so that music data capable of obtaining high-quality reproduced musical sound, which is a large amount of data, is stored in, for example, 32 words. Even if the FIFO 31 that can only store the data is used, the data can be reproduced.

Referring to FIG. 6, a ring tone mode of the portable telephone 1 will be described. As described above, in this portable telephone, the beep sound generated by the beep sound generation unit 17 as the ringtone, the sound reproduced by the recording and reproduction unit 16, and the music performance unit 1
5 can be used, and these can be combined into a ringtone. The various combinations can be set as the ringtone mode. Mode 1 is a mode in which a beep sound is continuously generated. Mode 2 is a mode in which sound is repeatedly generated. That is, since the voice data has a finite length, it is necessary to repeatedly reproduce the voice data in order to continue the call reception (hook off). Mode 3 is a mode in which musical sounds are continuously generated. However, this musical tone is not a so-called musical performance sound but a musical tone created as a ring tone, such as a bell sound of an old telephone.

The mode 4 is a mode in which a beep sound is first generated to notify that there is an incoming call, and then a musical sound (musical performance sound) is generated. Thereby, even if the performance sound of the music is high quality and natural, it is possible to notify the user of the incoming call. Similarly to the mode 4, the mode 5 and the mode 6 are also modes for generating a ringing tone of a voice or a musical tone, notifying that there is an incoming call, and then generating a musical tone (musical performance sound).

Modes 7, 8, and 9 are modes in which the operations of modes 4, 5, and 6 are repeated (until a response is made). Further, in the mode 10, mode 11, and mode 12, in the operation of the mode 7, the mode 8, and the mode 9, the beep sound (sound and ringing sound of music) is changed from the beep sound to the musical sound, and the musical sound is changed to the beep sound (sound ringing sound of the music and music). Is a mode in which switching is performed by crossfading.

The switching between the beep sound, the voice and the musical tone in the mode 4, the mode 5, the mode 7, the mode 8, the mode 10, and the mode 11 is performed by operating the beep sound generating section 17, the recording / reproducing section 16 and the music playing section 15. Variable gain amplifiers 18a, 18b, 18c
This is done by controlling the gain of The cross-fade is performed by gradually increasing the output gain of one from 0 to 1 and gradually decreasing the output gain of 1 from 0 while generating two acoustic signals. On the other hand, the switching between the ringing tone (bell sound) of the musical sound in mode 6, mode 9, and mode 12 and the performance sound of the music is performed by controlling the output level of each part in the sound source section 35.

The operation of the portable telephone will be described with reference to the flowcharts of FIGS. FIG. 7 is a flowchart showing the operation during standby. In the standby operation, while waiting for an incoming call from another telephone, it is possible to select a musical piece to be played at the time of incoming call or hold, select audio data to be played back at the time of incoming call, and the like. When the ringtone mode is selected by a user operation during standby (s
1) The selected mode number is set in the system RAM 11 (s2). Further, when music data to be played at the time of an incoming call or a hold is selected (s3), the selected music data is set in the music playing unit 15 (s4). That is, the timbre data of the music data is set in the timbre data storage unit 34, and the first 32
Set word in FIFO 31. When the audio data is selected (s5), the selected audio data is set in the recording / reproducing unit 16 (s6). When the performance of the music is instructed (s7), the start of the performance is instructed to the music performance unit 15 and the musical sound of the performance is emitted from the calling speaker 20 (s8). The performance of the music in this scene is performed when the user wants to listen to the music irrespective of the call or when the performance is used for karaoke.

When there is an incoming call from another telephone (s9),
The following operation is executed. If there is no incoming call, while performing other processing such as updating the clock display (s1
0) Wait until there is a user operation or an incoming call. When there is an incoming call (s9), a ringtone is generated in the ringtone mode set in s1 and s2. System CPU 10
Controls the operations of the beep generating unit 17, the recording / reproducing unit 16 and the music playing unit 15 in the pattern shown in FIG. 6, and controls the variable gain amplifiers 18a, 18b, 18c and 21.
The gain of b is controlled. If the user responds to the incoming call (s12), the ringtone is stopped (s14), and FIG.
Proceed to the in-call operation. If the incoming call disappears without answering (s13), the ringtone is stopped (s15), and the process returns to s1.

FIG. 8 is a flowchart showing the operation during a call. When the user turns on the response button to respond, the communication unit 13 transmits a response signal to the base station to set a call state (s20). Then, the microphone 28 is turned on to enable a call (s21). When the microphone 28 is turned on, the audio signal input from the microphone is input to the coder of the audio processing unit 14, and the gain of the amplifier 21a is increased to receive the audio signal and the reception signal received by the antenna 1a and input from the communication unit 13. Is output from the receiving speaker 23. As a result, the user can talk with the other party, and the system CPU 10 waits until there is an operation by the user while performing other processing such as displaying the talk time (s30).

Then, during a call, B
When the GM performance is turned on, the music set in the music performance section 15 at that time is played, and this musical tone is reproduced by the amplifier 21b.
And outputs it to the coder of the audio processing unit 14. At this time, the gain of the amplifier 21b is increased so that this musical sound is output from the receiving speaker 23. As a result, the musical sound is emitted from the receiving speaker 23 as BGM of the call, and is transmitted to the other party together with the transmitted voice. When the BGM is turned off during the performance of the BGM (s27),
Instructing the music performance section 15 to stop the performance, the gain of the variable gain amplifier 21b is reduced, and the performance of the BGM is stopped (s28).

When the hold button is turned on (s2
9) At the same time, the microphone is turned off (s31), and the music playing section 15 is instructed to play the music, and the musical tones of this performance are output to the amplifier 21b and the coder of the audio processing section 14 (s3).
2). In this process, the gain of the amplifier 21a is reduced, and the gain of the amplifier 21b is increased. In the audio processing unit 14, the signal input to the coder is
8 is switched to a tone input from the music playing section 15. In other words, the difference from the BGM performance is that the sound of the microphone 28 is not output from the other party or the receiving speaker 23. This state is maintained until the hold is released by the user. When the hold is released (s33), the music playing unit 15 is instructed to stop playing the music, and the gain of the amplifier 21a is reduced to stop the tone as the hold sound (s34). Then, returning to s21, the microphone is turned on. That is, the input of the coder of the audio processing unit 14 is switched to the input audio of the microphone 28, and the gain of the amplifier 21a is increased.

When the call ends and the hook-on button is turned on (s22), the microphone is turned off (s23), and the communication unit 13 transmits a signal indicating the end of the call to the base station to release the call state. (S24). Thereafter, the operation returns to the standby operation.

In this description, the calling process from the telephone is omitted for the sake of simplicity. However, when a call is established from the mobile phone, the in-call process of FIG. 8 is executed when a call is established. .

The pattern of the ring tone mode is not limited to the pattern shown in FIG. For example, all the sound signal generating means may be operated in the order of beep sound-voice-music sound. The sound signal may be generated by repeating such as voice-tone-beep-tone.

[0044]

As described above, according to the present invention, all or a part of a plurality of sound signal generating means are switched and operated, and a plurality of kinds of sound signals are sequentially switched and outputted, so that various features are provided. It is possible to generate an acoustic signal having a certain level. In addition, by using the performance sound of the music as the ring tone corresponding to the call, the incoming call can be notified with a non-irritating musical tone, and in this case, the incoming call is generated by generating a beep sound or voice first. Can be noticed to the user.

Further, according to the present invention, it is possible to generate a ringing tone similar to the bell sound of a conventional wired telephone,
With such an acoustic bell sound, the degree of discomfort to surrounding people, such as the ringing tone of the current mobile phone, is reduced.
