Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of the information terminal device 1 according to the embodiment, and FIG. 2 is a functional block diagram of the information terminal device 1. The information terminal device 1 is a PDA (personal digital assistant device) with a data communication function.
[0008]
In FIG. 1, reference numeral 2 denotes a CPU (Central Processing Unit) that controls each part of the apparatus and functions as a sequencer or the like to be described later. Reference numeral 3 denotes a ROM (read only memory) in which a program of the CPU 2 is stored, and 4 denotes a nonvolatile RAM (random access memory) for data storage. The RAM 4 stores a plurality of pieces of music data as MIDI data in advance. Reference numeral 5 denotes a communication interface for connecting the information terminal device 1 to a telephone line, and reference numeral 6 denotes an infrared interface. The infrared interface 6 converts the data supplied from the CPU 2 into an infrared signal and outputs it to the outside, and also demodulates the infrared signal received from the outside into digital data and outputs it to the CPU 2.
[0009]
Reference numeral 7 denotes a display unit including a liquid crystal panel and a driving circuit thereof, and performs image display based on display data supplied from the CPU 2. An operation unit 8 includes a numeric keypad, alphabet keys, function keys, and a key interface. An audio input interface 9 samples audio input from a microphone (not shown), converts it into digital data, and outputs it to the CPU 2. A tone generator circuit 10 forms a digital musical sound waveform based on a musical sound parameter supplied from the CPU 2, converts the formed musical sound waveform into an analog signal, and outputs the analog signal to a speaker (not shown).
[0010]
Next, in FIG. 2, 4a is a database formed in the RAM 4 and includes a personal information database and a music database. As shown in FIG. 3, “name”, “address”, “phone number”, and “melody file name” are recorded in the personal information database. In the music database, MIDI data of a plurality of music is recorded with a melody file name assigned to each music. A sequencer 2 a is executed by the CPU 2, reads designated music data (MIDI data) in the music database in the database 4 a, converts it into musical tone parameters, and outputs it to the tone generator circuit 10. The tone generator circuit 10 forms a digital musical sound waveform based on the parameters supplied from the sequencer 2 a and outputs the digital musical sound waveform to the speaker 11.
[0011]
An audio processing circuit 12 is executed by the audio input interface 9 and the CPU 2 and processes audio input from a microphone (not shown) (details will be described later). A music data server 13 is connected to the information terminal device 1 via the Internet, and receives music data (MIDI data) in response to a request from the information terminal device 1. The distributed music data is stored in the music database of the database 4a. Reference numerals 14 to 16 denote information terminal devices configured in the same manner as the information terminal device 1, and perform data communication with the information terminal device 1 using infrared rays.
[0012]
Next, operation | movement of the information terminal device 1 mentioned above is demonstrated.
(1) Personal Information Input FIG. 4 is a flowchart showing the personal information input operation. A user who wants to input personal information first instructs personal information input using the keys of the operation unit 8. When this instruction is performed, the CPU 2 detects it and displays each personal information on the display unit 7, that is,
Displays fields for entering name, address, and phone number.
[0013]
When the user inputs predetermined data in each field (step Sa1 in FIG. 4), the CPU 2 writes the input data in the work area of the RAM 4 (step Sa2). Next, the CPU 2 displays a list of music data stored in the music database of the RAM 4 on the display unit 7 and also displays a guidance “Please select a melody”. Here, when the user selects one of the lists with the cursor (step Sa3), the file name of the selected music data is written in the work area of the RAM 4 (step Sa4).
[0014]
Next, the CPU 2 displays the set personal information , that is, the name, address, telephone number, and melody file name on the display unit 7. The user checks the display (step Sa5), and if correction is necessary, the user returns to the initial time point or the melody input time point and performs re-input. If there is no need for correction, “OK” is input from the operation unit 8. When this “OK” is input, the CPU 2 registers all data in the work area of the RAM 4 in the personal information database (step Sa6).
[0015]
(2) Personal information transmission This information terminal device 1 can transmit its own personal information to the information terminal device of the other party in the face just like business card exchange. FIG. 5 is a flowchart showing the process in that case.
[0016]
In this case, the user of the information terminal device 1 first instructs personal information transmission from the operation unit 8. When this instruction is given, the CPU 2 displays a list of only the “name” of each personal information in the personal information database in the RAM 4 on the display unit 7. When the user selects a personal name (for example, his / her name) with the cursor (step Sb1), the CPU 2 reads each personal information of the selected personal name from the personal information database in the RAM 4, outputs it to the infrared interface 6, and then Based on the “melody file name” included in the personal information, the music data in the music database is read and output to the infrared interface 6 (step Sb2). The infrared interface 6 converts the personal information and music data into infrared signals and transmits them (step Sb3).
[0017]
Now, assuming that the user of the information terminal device 1 and the user of the information terminal device 14 are facing each other, the infrared signal transmitted from the information terminal device 1 is received by the infrared interface 6 of the information terminal device 14. The infrared interface 6 of the information terminal device 14 demodulates the received infrared signal into the original personal information and music data and outputs it to the CPU 2 (step Sb4). The CPU 2 writes the personal information received from the infrared interface 6 to the personal information database in the RAM 4, and then writes the music data to the music database with a file name (step Sb5).
[0018]
(3) When the user of the personal melody confirmation information terminal device 1 wishes to confirm the melody set for each individual, a database search by name is performed. That is, when the user instructs the personal information database search from the operation unit 8, the CPU 2 displays a list of names registered in the personal information database on the display unit 7. When the user selects a name with the cursor, the CPU 2 displays personal information of the selected name on the display unit 7. Next, the CPU 2 reads the music data from the music database based on the melody file name included in the personal information, converts it into a musical tone parameter, and outputs it to the tone generator circuit 10. As a result, a melody attached to the personal information displayed on the display unit 7 is generated from the speaker 11. This melody generation can be set to off / off.
[0019]
(4) Personal information search by melody The information terminal device 1 can search personal information by inputting a melody from a microphone, for example, by humming. FIG. 6 is a flowchart showing the processing in this case. When performing this melody search, the user inputs the melody of the person who wants to search from the microphone by humming. Here, the melody of the person who wants to search is the melody of the music data indicated by the “melody file name” registered together with the person's name in the personal information database.
[0020]
When the user inputs a melody from the microphone (step Sc1), the voice input interface 9 samples the voice signal input from the microphone and converts it into voice data, and then detects a change of the pitch of the voice data with respect to time. Then, the detection result is converted into MIDI data and output to the CPU 2 (step Sc2). The CPU 2 compares the supplied MIDI data with each piece of music data (MIDI data) in the music database of the RAM 4 (step Sc3), and searches for MIDI data that substantially matches the input voice (step Sc4). In this case, if the search is not performed for the first time, re-detection is performed by changing the allowable width of the data (step Sc5). If it can be detected, data in which the file name of the MIDI data is registered as the melody file name is read from the personal information database and displayed on the display unit 7 (step Sc6). On the other hand, if it cannot be detected even after re-detection (step Sc6), an error is displayed and the process is terminated (step Sc7).
[0021]
In the above embodiment, the music database in the RAM 4 may be downloaded by accessing the server 13 (FIG. 2), or may be input by the user himself / herself from the microphone, or at the factory at the time of shipment. It may be preset, or music data used as a ringing melody in another mobile terminal may be transferred. Further, MIDI data is formed by inputting a musical score on a personal computer or the like, and the data is wired or infrared. You may forward by.
The present invention can be applied not only to a PDA but also to a mobile phone, a PHS (registered trademark), and the like.
[0022]
