  The sound generation control ROM 34 stores a plurality of predetermined music information for incoming melody or BGM, performance information, setting information, conversion table for information format conversion, and compression table for information compression. A plurality of newly added or newly created music information, performance information, and setting information can be stored.

  In this example, the sound source circuit 36 is an FM sound source, and can simultaneously generate a plurality of sounds. The tone color is set based on the setting information related to the tone color transmitted from the tone generation control ROM 34 and the tone generation control RAM 35 via the tone generation control BUS 40. The tone generator circuit 36 sequentially synthesizes tone signals corresponding to the set tone color based on the performance information transmitted from the tone generation control ROM 34 and the tone generation control RAM 35 under the control of the tone generation control CPU 31 and timer 33, and the MIX 38 Output to.

  The effect circuit 37 sets the effect to be given to the musical sound based on the setting information regarding the effect transmitted from the sound generation control ROM 34 and the sound generation control RAM 35 via the sound generation control BUS 40. The effect circuit 37 also applies an effect to the signal input from the MIX 38, the speech sound signal ST input from the communication circuit 32, and the like, and outputs the applied signal SE to the MIX 38 again.

The MIX 38 sums up the input signals and outputs them to the digital-to-analog converter circuit (DAC) 41 and the digital output terminal 18. The signal input to MIX38
(1) The synthesized musical tone signal SM from the tone generator circuit 36,
(2) Call sound signal ST from the audio control circuit 7;
(3) After-effect signal SE from the effect circuit 37
and so on. The MIX 38 selectively outputs the input signals SM and ST to the effect circuit 37 to give the effect, and the output signal is set by operating a predetermined switch of the operation unit 12 on the terminal system TS main body side.

  The amplitude control circuit (VOL) 39 and the amplifier circuit (AMP) 42 constitute an analog output device, the volume of the analog tone signal output from the DAC 41 is adjusted by the VOL 39, and the volume-adjusted analog tone signal is sent from the headphone terminal. In addition to being output to the audio control circuit 7, it is further transmitted to the sound generation speaker 17 via the AMP 42.

[Terminal system usage environment]
FIG. 4 is a conceptual diagram showing an example of the usage environment of the portable telephone terminal according to one embodiment of the present invention. In the first environment, when a call is made from the portable telephone terminal (terminal system) TS to the base station (server station) BS via the transmission / reception circuit 6, the desired music information or the like is selected and the transmission is requested. Information or the like is transmitted from the base station BS, downloaded into the terminal system TS, and using this information, a melody sound at the time of incoming call or a BGM sound during a call can be generated.

  In the second environment, the terminal system TS receives music information or the like created by the personal computer terminal PC via the communication cable 20 connected to the communication I / F 10, and uses this as melody or BGM. Can do.

  In the third environment, the terminal system TS introduces music information or the like recorded on the small external recording medium 19 attached to the connection circuit 9 from the recording medium 19, and in the fourth environment From the telephone terminal OS, the music information and the like of the other telephone terminal OS are received via the telephone line and the transmission / reception circuit 6 via the base station BS, or via the communication cable 20 and the communication I / F 10. Can be used for musical tone pronunciation.

  Music information introduced into the terminal system TS from music information sources such as the base station BS, personal computer terminal PC, external storage medium 19 or other telephone terminal OS is edited in the information source BS, PC or system TS. Downsized to usable form by compression, format conversion, etc.

  For example, the music information (including performance information and setting information) introduced into the terminal system TS from these music information sources may be in a format suitable for the own model or in another format. When a format suitable for the model is introduced, it is created in advance in this format, or is converted from another format (format conversion). This format conversion can be performed by the base station BS or personal It is performed in the computer terminal PC. When another format is introduced into the terminal system TS, the other format is converted into the format in the terminal system TS in the terminal system TS.

[Information format]
FIG. 5 shows an example of the information format of the own model in the portable telephone terminal according to one embodiment of the present invention. As shown in FIG. 5, the portable phone terminal system TS and the “music information IA corresponding to its own model” that can be handled in another phone terminal of the same model that performs information processing in the same format as the terminal system TS, It consists of setting information SA for setting tone color / effect and performance information MA for musical tone performance. Each information SA, MA is recorded with only the minimum necessary information so that the storage capacity of the memory (RAM 3) in the terminal system is not compressed and a better tone can be generated. In the terminal system TS, sound generation control is performed according to these pieces of information. Hereinafter, this type of information format is referred to as “own model format A”.

The setting information SA is related to the tone.
(1) Tone number NA for identifying the tone type,
(2) Detailed information (tone parameter) DA for setting the tone in the tone generator circuit
Is included. The timbre parameter DA of (2) includes algorithm data AA, frequency parameter (F parameter) FA, envelope parameter (EG parameter) EA, and the like.

  The algorithm data AA is a parameter for determining a combination or algorithm of a plurality of operators (sine wave memory + output level calculator + envelope (EG) waveform synthesizer set) in the FM sound source. Each operator is a parameter for determining the frequency of the readout sine wave, and the EG parameter EA is a parameter for setting a plurality of level values and rate values for synthesizing the envelope waveform (EG waveform). .

  In addition to the tone color setting information NA and DA, the setting information SA includes information for setting effect parameters, an effect program (DSP program) for determining the contents of the effect circuit 25, sound information, image information, and the like. There is.

  The performance information MA is information in which performance information composed of timing data TM, key number KN, gate time GT, and the like is recorded in the order of performance.

  FIG. 6 shows an example of a conventional information format in another type of portable telephone terminal. As shown in FIG. 6, the conventional type music information IB used as the incoming melody information in the portable telephone terminal is only performance information represented by a symbol string composed of symbols a, b, c,. There is no setting information. Hereinafter, this type of information format is referred to as “conventional format B”.

  More specifically, the performance information IB of the other models is information in which symbols (#, 1, 2, 3,...) Are arranged in the order of musical performance according to a predetermined rule. For example, the number “1” corresponds to the pitch of “do”, the number “2” corresponds to the pitch of “re”, and so on. Stipulate. Therefore, when “1-1-2-1-1-...” Is represented by the symbol strings a, b, c,... Represents a musical sound in which "" is pronounced in eighth note length and then "do" is pronounced in quarter note length again.

  FIG. 7 shows an example of a general-purpose musical sound information format conventionally used in electronic musical instruments and the like. In a conventional electronic musical instrument or the like, as shown in FIG. 7, in accordance with a general-purpose musical sound information format ["SMF" (Standard MIDI File) format], setting information SC for setting tone / effect and performance for musical performance. A musical tone information IC composed of information MC is used. Hereinafter, this type of information format is referred to as “SMF format C”.

Of the setting information SC, information for setting the tone is
(1) Tone number NC as tone color identification information,
(2) Detailed information DC for tone setting
It is composed of

  The timbre setting detailed information DC of (2) has a large amount of information unlike the music information IA for the terminal system TS as shown in FIG. For example, in addition to the algorithm data AC and F parameter FC, rate scale data RS for controlling the EG level according to the pitch to be generated is stored, and the content of the EG parameter EC also includes more detailed information. The number of level values and rate values is larger than the EG parameter EA in the setting information SA in the own model format A in FIG. Excess information in the detailed information DC is compressed as information that is not indispensable in the terminal system TS when the format is converted from the SMF format C to the own model format A in the system including the terminal system TS. (Deleted).

  The performance information MC is information in the “duration DR + event IV” format, and the key-on and key-off events are stored together with the duration data DR, so the amount of information is slightly increased. Also, velocity data is recorded for each key-on, and this velocity data is also compressed (deleted) at the time of format conversion to its own model format A.

[Information exchange with base stations]
8 and 9 are functional block diagrams showing information exchange relationships in the first system including the terminal system and the base station according to one embodiment of the present invention. In the present invention, the own terminal, that is, the portable telephone terminal system TS receives music information and setting information from the base station BS, but these information are converted in form as necessary on the base station BS side when the information is requested. Sometimes it is information available in the terminal system TS.

  First, the terminal system TS makes a call to the base station (server station) BS via the transmission / reception circuit 6 by the request information transmission module (S1), and in response to information in the database DB of the server station BS according to a predetermined instruction. Request download. Specifically, for example, during a call with the server station BS, music information, performance information, setting information and the like stored in the database DB are sequentially displayed on the display unit 13 of the own terminal system TS. The number corresponding to any of these pieces of information is key-inputted, and the request determination operation is performed to select the selection information representing the requested download target information, the model / machine number of the terminal system TS, and the terminal Identification information indicating the type of sound source installed in the sound source circuit 24 of the system TS is transmitted to the server station BS.

  In the server station BS, in response to the request information being transmitted from the terminal system TS, the selective reading module (B1) selectively reads out the music information corresponding to the request information from the database DB and reads it. In the case of the own model format A, the performance information and the like that has been output are immediately handed to the billing module (B2) because format conversion (format conversion) is unnecessary. On the other hand, when the read performance information or the like is in a format different from the own model such as the conventional format B, it is sent to the billing module (B2) via the setting information attachment module (B3) and the format conversion module (B4). Handed over.

In the setting information attachment module (B3), if the read performance information in a format different from that of the own model does not have setting information, such as information in the conventional format B, the setting information is displayed. Attach. By attaching this setting information, even with performance information of other models that do not have the setting information, the terminal system TS can perform tone reproduction with an effective tone / effect utilizing the sound source function. Become. In the setting information attachment method,
(1) Attach predetermined setting information.
(2) Attach user-selected setting information;
(3) There is a method of automatically detecting and attaching setting information that is familiar with performance information.

  The performance information to which the setting information is attached is handed to the format conversion module (B4), and format conversion to the own model format A is automatically performed using a conversion table TB prepared in advance. This conversion table TB is prepared for each format combination before format conversion and after format conversion. For example, the conversion table TB is a table describing conversion rules from the conventional format B to the own model format A. Format conversion from format (B) to own model format A is performed.

  Although the format of other models is not illustrated in FIG. 9, there is a case of SMF format C in addition to the conventional format B. For example, when information of SMF format C is read, Format conversion is performed using a conversion rule from the SMF format C to the own model format A in the conversion table TB. Therefore, even if the requested information is from other models (B, C, etc.), the format conversion function converts the requested information into music information IA that can be generated by the own terminal system TS, and is used in the terminal system TS. Enable.

  Thereafter, in the billing module (B2), billing work for download is performed. In this work, a specific model or a specific sound source device (specific contract with a server station, etc.) is equipped by referring to the identification information (terminal model / machine number, sound source type) transmitted from the terminal system TS. If the terminal is recognized, the billing amount can be discounted.

  After the accounting work, the server station BS transmits the music format information and setting information of its own model format A corresponding to the selection information from the terminal system TS to the system TS side by the information transmission module (B5).

  On the other hand, in the terminal system TS, the information reception module (S2) receives and downloads music information and setting information from the server station BS via the transmission / reception circuit 6, and the downloaded information is stored in the main body RAM 3. Here, the terminal system TS may be in a call state from when it is requested by the request information transmission module (S1) until the information corresponding to the request is completely transmitted from the base station BS. Alternatively, the call may be temporarily canceled after the request information is transmitted, and the requested information may be received by a subsequent call process (email or a reply call from the base station BS).

  Then, in the setting module (S3), a setting operation is performed so that a ringing melody can be generated based on the received music information by a user's setting operation. The received information can be set to be reproduced as BGM at the time of a call, music at any time, or the like.

[Information exchange with personal computers]
FIG. 10 is a functional block diagram showing the information exchange relationship in the second system including the terminal system and the personal computer according to one embodiment of the present invention. In the present invention, the own terminal, that is, the portable telephone terminal system TS can receive music information and setting information created on the personal computer terminal PC and use these information. The music information and setting information can be created in any format. For example, it can be created in accordance with the conventional SMF format C because of its good operability. If it is different from the own model format A, format conversion (format conversion) to the own model format A is performed at the time of transmission. Done.

  In the personal computer terminal PC, using the predetermined software installed, from the database DP in the computer terminal PC in which information is recorded in the SMF format C or the own model format A by the selective reading module (P1), When music information or setting information to be used as an incoming melody or BGM is selected, the selected music information or setting information is edited by the information editing module (P2) accordingly. Examples of the editing work include changing or adding a timbre parameter or an effect parameter in the setting information, selecting a part to be used as an incoming melody or BGM, etc. from performance information in the music information, or selecting the selected music For example, “trial sound generation” is performed in the same setting as when the information is sounded on the terminal system TS side, that is, in a setting state such as a timbre and an effect based on the compressed setting information.

  On the other hand, when newly creating music information on a personal computer terminal PC, for example, using conventional SMF type sequencer software (music information creation software) installed on the computer terminal PC, for example, The module (P3) creates new music information manually input by the user. The new music information created here is music information according to the SMF format C, for example.

  The new creation module (P3) can also automatically create new music information using automatic music software (apparatus). Applying this platform, conventional automatic music software or automatic music device, for example, from the music information for one music created with the conventional automatic music software, only the music in the desired section (such as rust) Cut out only the information of the minimum necessary track (melody track, chord track, etc.) from the music information composed of multiple tracks so that it can be connected well when the music information of the cut out section is played repeatedly It is possible to perform operations such as correcting the connecting portion (section head and section end position). The new creation module (P3) can also directly create music information corresponding to the incoming melody or BGM in its own model format A.

  Of the information that has been read or edited from the information editing module (P2) and the information that has been newly created by the new creation module (P3), information that is not in its own model format A, such as SMF format C, Information compression and format conversion are performed by the information compression module (P4) and the format conversion module (P5). On the other hand, the information of the own model format A is immediately handed to the information transmission module (P6).

  Information that is not in its own model format A is first compressed by the information compression module (P4) using the compression table TE prepared in advance so that it can be stored in the terminal system TS. This compression table TE is prepared for each format combination before compression and after compression, and describes a predetermined information compression rule. As a specific example of processing based on this information compression rule, unnecessary information such as the rate scale RS of the already explained SMF format C (see FIG. 7) or excessive information in the EG parameter EC is converted into its own format A. In addition to processing that is sometimes reduced, performance information of necessary tracks (only melody tracks and chord tracks, etc.) is extracted from performance information of multiple tracks, decoration sounds in performance information are deleted, pitch bend in performance information There are processes such as changing the data to pitch data.

  The compressed information is further converted by the following format conversion module (P5) using the conversion table TC in the same manner as the format conversion module (B4) in the embodiment (first system) of FIGS. Format conversion from SMF format C to own model format A is performed.

  Originally, the music information or setting information from the module (P2, P3) which is the own model format A, and the music information or setting information from the module (P5) compressed and converted into the own model format A are the information transmission module ( By P6), it is transmitted to the terminal system TS side and sent into the terminal system TS via the communication cable 20 and the communication I / F 10.

  On the other hand, in the terminal system TS, music information and setting information from the personal computer terminal PC side S are received and stored in the main body RAM 3 by the information receiving module (T1). Further, in the setting module (T2), the user performs a setting operation so as to enable ringing melody pronunciation and BGM pronunciation based on the received music information.

In this reading, only desired information can be read by operating a predetermined switch in the operator 12 of the own terminal system TS.

  Information transmitted from another telephone terminal OSa is taken into the own terminal system TS from the transmission / reception circuit 6 via the telephone line via the base station BS. Information transmitted from another telephone terminal OSb is taken into the own terminal system TS from the communication I / F 10 via the communication cable 20. These telephone terminals OSa and OSb include the same model telephone terminal that uses the same format information as the own model format A, and the own model format A such as the conventional format B and SMF format C. May be a heterogeneous telephone terminal that uses different format information.

  When information is transmitted from other telephone terminals OSa and OSb, information indicating in which format the information is created is attached to each information to be transmitted. It should be noted that setting and using the received information in real time (that is, setting and using immediately after reception in the local terminal system TS) in the local terminal system TS that is the receiving side terminal is another telephone that is the information transmitting side terminal. You may comprise so that it can request | require on the terminal OSa and OSb side. Further, when information is transmitted through the base station BS, the information may be transmitted to the receiving terminal (own terminal) after the base station BS performs information compression or format conversion.

  As described above, the information receiving / reading module (U1) reads music information, performance information, setting information, and the like from the external storage medium 19, and takes in various pieces of similar information transmitted from other telephone terminals OSa and OSb. In addition, among the read information or received information, the information of the conventional format B or SMF format C is a series of setting information attachment module (U2), information compression module (U3), and format conversion module (U4). After being compressed / converted via, it is handed over to the information recording / editing module (U5), and the information of the own model format A is handed over to the information recording / editing module (U5) as it is.

For example, audio information includes formats such as WAVE, AIFF, SOUND VQ, MP3, etc. depending on the compression format, but the common format is used so that audio information in these formats can be captured, and the audio information is used. In parallel with the generation of the musical sound signal, a guidance voice signal can be generated.

  Further, as examples of using image information, an icon corresponding to the incoming call or the other party is displayed on the display unit 13 of the terminal system TS, and the movement of the icon is controlled to be synchronized with the reproduction of the musical sound, or the musical sound signal is used. The corresponding musical score can be displayed sequentially.

[Various Embodiments]
The format of the musical sound information that can be used in the portable terminal device is not limited to the own model format A. For example, the sound generation control circuit as shown in FIG. 3 is installed, and the music performance information in SMF format C is reproduced as it is by operating an automatic performance function (sequencer) used in a conventional electronic musical instrument. It is also possible to make it possible. In this case, it is not necessary to convert the format when information is taken from another musical tone information source device (such as a PC) to the portable telephone terminal. However, it is preferable to perform the compression process.

  In the embodiment, the FM method is adopted as the tone synthesis method in the tone generator circuit, but the tone synthesis method is not limited to this. For example, various methods such as a waveform memory method, a physical model method, a harmonic synthesis method, a formant synthesis method, and an analog synthesizer method of “VCO + VCF + VGA” can be applied. In other words, various information related to the timbre recorded as setting information differs depending on the tone synthesis method of the tone generator circuit, but basically various parameters corresponding to each tone synthesis method used in electronic musical instruments conventionally. Information can be employed.

  In addition, the tone generator circuit itself is not limited to the configuration of the tone generator circuit using dedicated hardware, but the tone generator circuit may be configured using “DSP + microprogram” or “CPU + software”. The tone generator circuit may be configured by a program.

  Further, a plurality of tone generation channels may be formed by using one circuit in a time division manner, or a type in which one tone generation channel is constituted by one circuit may be used.
