Description

  The present invention relates to a mobile phone that notifies an incoming signal with a ring tone, and more particularly to a mobile phone that is suitable for notifying a user of a condition at the time of an incoming call with a ring tone.

  The ringtone in a conventional mobile phone is generally based on a number of tone data obtained by digitally encoding a tone signal. When an incoming call arrives, the ring tone sounds, and the user simply notices that his / her mobile phone is on the phone. However, the number of mobile phone users is increasing rapidly, and more people have mobile phones at the same place. For this reason, since there are users who receive an incoming call to another person's mobile phone that is different from an incoming call to his / her mobile phone, it is necessary to distinguish the ringtone of each mobile phone. For example, it has become popular that each person creates a unique melody by means of melody generating means for differentiation. Further, there is a function for updating a melody by downloading as in Patent Document 1, and a means for creating a unique ringtone by capturing a ringtone from an external microphone in advance as in Patent Document 2. Most recently, a means for synthesizing sounds from a sound database, such as the FM sound source method, so that the timbre of an instrument can be played has been announced.

In addition to differentiating from another person's mobile phone, means for changing the ring tone and the light emission pattern by the other party who made the call as in Patent Document 3 has come to be used. As a result, it is possible to increase the utility value such as knowing the caller just by listening to the ringtone.

  In the past, it was easier to hear melodic sounds than by using a mechanical beep sound earlier than that by simply expanding the frequency range for creating the beep sound or making the tempo variable. . In addition, there is an FM sound source method for synthesizing sounds from a sound database, but this also only reproduces specific sounds such as musical instruments, and cannot create human voices. In addition, if the PCM sound source method or the like is simply used, human voices and sound effects can be created and ringtones can be created indefinitely. However, for mobile phones that require small size and light weight, the capacity of data to be retained The problem arises that becomes too large.

Is output.

  As shown in FIG. 2, the reproduction timing storage unit 1 stores a sound data number to be reproduced, the timing of each reproduction, and the like. The sound data numbers correspond to FM sound source method sound data No. 1, PCM sound source method sound data No. 2, and MIDI method sound data No. 3, respectively. The sound data is not limited to the above, and MP3 sound data can also be used, and No. 4 is assigned as the sound data number. Hereinafter, every time sound data is added, sound data numbers 5 and 6 are assigned. The pattern number can be changed according to the telephone number of the other party or can be changed according to the incoming time. The setting method and type will be described in detail later. The reproduction timing is controlled by ON and OFF, and the sound data is reproduced when ON, and is not reproduced when OFF.

  Next, a pattern number setting method will be described. FIG. 16 is a front view showing a schematic appearance of the mobile phone according to the present embodiment. A speaker 1602 serving as a receiver is provided at one end on the front surface of the telephone main body 1601 (the surface on which keys, a display, a microphone, a speaker, and the like operated by the user are provided). An operation key is provided. Among the various operation keys, an up key 1604, a down key 1605, a left key 1606, and a right key 1607 for moving the cursor displayed on the display unit up, down, left and right respectively, and confirming the input contents A key 1608, a clear key 1609 for deleting input contents and canceling an operation, and a function key 1610 for selecting or executing various functions are included. The up key 1604, the down key 1605, the left key 1606, the right key 1607, and the confirm key 1608 are assigned some numeric keys for inputting a telephone number, time, and the like. A microphone 1513 as a transmitter is provided at the other end, but is not shown in the figure.

  A method for changing the ring tone by the telephone number of the caller by operating the above keys will be described. Examples of the display screen of the display unit 1603 at this time are shown in FIGS. 17 (a), 17 (b), and 17 (c). First, the function key 1610 and the key assigned to the menu screen selection are pressed to go to the “ringtone change menu screen” (d1) shown in FIG. In this case, selection is made as to what to change the ringtone for, and for example, it can be changed according to the other party's telephone number, incoming date and time, and the number of missed calls. An inequality sign “>” is displayed on the left side of the selection item as a cursor indicating the item to be selected. Therefore, the cursor is moved by pressing the up key 1604 or the down key 1605 and the tip of the inequality sign “>” (in this case, the acute angle portion on the right side) is adjusted to the item to be selected. If you want to change the ring tone by phone number, select “1. Phone number of the other party” and press the enter key. Then, the screen shifts to a “ringtone change screen by the other party's telephone number” (d2) shown in FIG. In this screen, the telephone number of the other party can be selected by moving the cursor by pressing the upper key 1604 or the lower key 1605, selecting the telephone number whose ringtone you want to change, and pressing the enter key. The telephone number of the other party may be directly input using a numeric key. When the confirmation key is pressed after selecting the telephone number, the screen shifts to the “ringtone pattern selection screen” (d3) shown in FIG. 17C, and the ringtone pattern corresponding to the selected telephone number can be selected. . There, the cursor is moved by pressing the upper key 1604 or the lower key 1605, and a desired pattern number is selected. In the mobile phone of this embodiment, every time a pattern is selected, a ringtone for that pattern is reproduced from the speaker 1602, and the pattern can be confirmed. Here, the ring tone can be set by selecting “2. pattern number 2” as the desired pattern and pressing the enter key. In the pattern number 2, as shown in FIG. 2, the sound data of the FM sound source of the sound data number 1, the PCM sound source of the sound data number 2, and the MP3 sound source of the sound data number 4 are reproduced at the timing shown in FIG. To return the screen to the previous screen, the user can return to the screen of (d2) by pressing the clear key 1609 on the screen of (d3). Similarly, when the clear key 1609 is pressed on the screen (d2), the screen (d1) can be returned.

  Next, the process until sound data is reproduced will be described with reference to FIG. 1, FIG. 2, FIG. 3, FIG. Here, as an example, a method of selecting and reproducing a pattern number from a caller's telephone number will be described. FIG. 3 is a block diagram showing functional blocks necessary for selecting a pattern number from the telephone number of the caller. Referring to the circuit configuration of the mobile phone shown in FIG. 15, the receiving unit 101 that receives a radio signal is a receiving circuit part included in the radio unit 1511 in FIG. 15, and the telephone number detecting unit 102 is shown in FIG. A communication control unit 1516 detects a telephone number after demodulation of a radio signal in accordance with a program stored in the communication memory unit 1515. A part of the memory area of the communication memory unit 1515 in FIG. 15 is allocated as the pattern number storage unit 103, and the phone number and the ring tone pattern number corresponding to each phone number are stored as shown in FIG. Yes. Incoming calls 103a and 103b for the telephone numbers set and stored in the pattern number storage unit 103, and incoming calls corresponding to a part of the telephone number, for example, incoming calls 103c and 103d for the area code of the caller's telephone number Sound pattern numbers can be stored, and various services can be developed according to the user's request. The communication control unit 1516 determines a pattern number corresponding to the detected telephone number based on the data stored in the pattern number storage unit 103, and thereafter, based on the data stored in the reproduction timing storage unit 1 in FIG. Then, the reproduction timing of the sound data corresponding to the pattern number is read out, and the process proceeds to the ring tone creation process.

  Hereinafter, a specific description will be given using a flowchart. In the flowchart of FIG. 18, at the time of an incoming call (s1), the other party's telephone number or the like is detected and a ring tone is selected (s2). If it is set to change the ringtone according to the telephone number of the other party, the receiving unit 101 receives and demodulates the radio signal when the mobile phone is called as shown in FIG. Is sent to the telephone number detection unit 102, and the telephone number detection unit 102 detects the telephone number of the caller (the other party) from the demodulated data. The signal corresponding to the telephone number is sent to the pattern number storage unit 103, and the pattern number set for the telephone number is output by collating with the telephone number stored here. If the other party's telephone number is “012-345-6789”, the ring tone of the pattern number “1” set for this number is reproduced as shown in FIG. The data number “1”, the sound data number “2”, and the sound data number “3” are reproduced. It is also possible to change the ringtone for each area where the caller lives by setting and storing a pattern number for each area code. For example, when the first three digits of the caller's telephone number are “045”, the ring tone having the pattern number “3” is reproduced, and the sound data number “3” in FIG. 2 is reproduced. Become.

  The control unit 2 accesses the reproduction timing storage unit 1 and starts searching for the reproduction timing of each sound data in FIG. 2 (s3). In the control unit 2, the reproduction timing (s4a) of the sound data number “1” (FM sound source method), the reproduction timing (s4b) of the sound data number “2” (PCM sound source method), and the sound data number “3” (MIDI sound source method) ) Playback timing (s4c) is checked. Here, since the sound data number “1” and the sound data number “3” are ON at the beginning of the ringing tone notification (point “a” in FIG. 2), the process proceeds to (s5a) and (s5c), respectively. Since the sound data number “2” is OFF, no processing is performed, and a search wait state is entered. The FM sound source method sound data reproduction unit 4a having the sound data number “1” reads the FM sound source method sound data 3a and sends it to the mixer (s5a). Similarly, the MIDI sound source method sound data reproducing unit 4c having the sound data number “3” reads the MIDI sound source method sound data 3c and sends it to the mixer (s5b). In the mixer 5, the two received sound data are mixed and passed to the speaker 6. The speaker 6 outputs the received sound data as a ringtone (s6). Thereafter, it is determined whether the search has been completed (s7). If the next reproduction timing is set, the next timing is searched (s8).

  After a while during reproduction of the sound data number “1” and the sound data number “3” (time b in FIG. 2), the sound data number “2” is also turned ON at the reproduction timing at time b (s4b). Then, the PCM sound source method sound data reproduction unit 4b having the sound data number "2" reads the PCM sound source method sound data 3b and sends it to the mixer (s5b). In the mixer 5, the three sound data sent are mixed and passed to the speaker 6. The speaker 6 outputs the received sound data as a ringtone (s6). Thereafter, it is determined whether the search has been completed (s7). If the next reproduction timing is set, the next timing is searched (s8). If the search has been made to the end, the reproduction of the ringtone is terminated (s9). Even in the course of all these processes, the reproduction of the ring tone data ends when the mobile phone user picks up the phone and starts a call (s9).

  By performing the above processing steps, it is possible to simultaneously reproduce sound data stored in a plurality of methods. If this method is used, memory data can be saved by setting the playback time to be short for sound data of the PCM sound source system having a large storage capacity. In addition, although the circuit scale may be slightly larger, it is possible to reproduce, for example, a human voice based on the PCM sound source system with the tone color of an instrument such as a piano or guitar based on the FM sound source system as a background. Main phrases are synthesized from a sound database such as the FM sound source method, and additionally, human voices and sound effects of the PCM sound source method can be used. As a result, when creating a ring tone, an infinite variation can be obtained and the capacity can be reduced. As a result, there are a wide variety of ringtones at the time of incoming calls, and differentiation from the ringtones of other people's mobile phones can be easily achieved.

  As an example of abundant ringtone variations, in addition to the above, when the name of the phone number holder stored in the pattern number storage unit is stored in advance as sound data of the PCM sound source method and reproduced as sound The name of the caller is the ringtone. For example, if the name of the caller is “Ieyasu Tokugawa” and “Tokugawa Yasu” is stored as the corresponding sound data, “Tokugawa Yasu” is reproduced by voice when the call is received. This is also effective when the caller is using a mobile phone. If the caller is using a telephone connected to the central office via a telephone line (including an optical cable), the area should be stored as PCM sound source sound data and played back as audio Thus, it is possible to know the other party's calling place when receiving a call. For example, if the area code of the caller is “045” and “Yokohama” is stored as the corresponding sound data, “Yokohama” is reproduced as a voice when receiving a call. In this way, it is possible to understand who has registered in advance and where the call originates by simply listening to the ring tone without taking a telephone call, and can respond appropriately.

  Next, another example of a pattern number selection method will be described as a second embodiment with reference to FIGS. In the present embodiment, the ring tone is changed by selecting the pattern number from the incoming time. Except for the control program and function of the communication control unit 1516 and the contents of the pattern number table stored in the communication memory unit 1515, the present embodiment is the same as the first embodiment. FIG. 5 is a block diagram showing functional blocks necessary for selecting a pattern number from the incoming time. Referring to the circuit configuration of the mobile phone shown in FIG. 15, the receiving unit 201 that receives a radio signal is a receiving circuit part included in the radio unit 1511 in FIG. 15, and includes an incoming time detection unit 202 and a clock function 204. Are the communication control unit 1516 of FIG. The clock function 204 counts time according to the program stored in the communication memory unit 1515 and outputs the time. The incoming time detection unit 202 detects the incoming time of the radio signal by the output of the clock function 204 when receiving information on the presence of an incoming call from the receiving unit 201 according to the program stored in the communication memory unit 1515. A part of the memory area of the communication memory unit 1515 in FIG. 15 is allocated as the pattern number storage unit 203, and the pattern number of the ringing tone corresponding to the incoming time is stored as shown in FIG. In the present embodiment, the pattern number storage unit 203 can store the pattern number of the ring tone corresponding to the incoming calls 203a and 203b for the set and stored time zone. The communication control unit 1516 determines a pattern number corresponding to the detected time based on the data stored in the pattern number storage unit 203, and thereafter, based on the data stored in the reproduction timing storage unit 1 of FIG. The reproduction timing of the sound data corresponding to the pattern number is read out, and the process proceeds to the ring tone creation process. In FIG. 6, as an example, when there is an incoming call from midnight to 8:00 am, pattern number “1” 203a is applied, and there is an incoming call from 5:15 pm to 9:30 pm Shows a setting for playing the ringtone of the pattern number “2” 203b. Specifically, when the incoming time is 1:00 am, since the first set time in FIG. 6 is from midnight to 8:00 am, the ringtone of pattern number “1”, that is, The sound data number “1”, the sound data number “2”, and the sound data number “3” in FIG. 2 are reproduced. Also, if there is an incoming call at 8:00 pm, the second set time is between 5:15 pm and 9:30 pm, so the ring tone of pattern number “2”, that is, The sound data number “1”, the sound data number “2”, and the sound data number “4” in FIG. 2 are reproduced. Thereby, the user can grasp | ascertain the present rough time only by hearing a ringtone. As a result, since the rough time can be grasped in various activities related to time, it is possible to take an action with a margin. In addition, the ringtone can be changed according to the time of day, so for example, a refreshing ringtone from midnight to early morning, or a loud and lively ringtone when you are in a noisy place after use, and use it for that time of day. It is also possible to make the ringtone suitable for the environment where the person will be.

  Further, by using the clock function 204, a calendar function can be obtained by setting the unit of time to day or month. This makes it possible to change the ringtone according to the day of the week, the weekday / holiday distinction at the time of the incoming call, or the month. Furthermore, it is possible to set a time at which a call should be made from a specific party and change the ringtone based on the time difference from the time at which the call is actually made.

  Next, a third example of the pattern number selection method will be described as a third embodiment with reference to FIGS.

  In the present embodiment, a ringing tone is changed by specifying a specific telephone number from the telephone number of the caller and selecting a pattern number based on the number of incoming calls from that telephone number. Except for the control program and function of the communication control unit 1516 and the contents of the pattern number table stored in the communication memory unit 1515, the present embodiment is the same as the first embodiment. FIG. 7 is a block diagram showing functional blocks necessary for selecting a pattern number from the number of incoming calls. Referring to the circuit configuration of the mobile phone shown in FIG. 15, the receiving unit 301 that receives a radio signal is a receiving circuit part included in the radio unit 1511 in FIG. 15, and the telephone number detecting unit 302 is shown in FIG. A communication control unit 1516 detects a telephone number after demodulating a radio signal according to a program stored in the communication memory unit 1515, and counts the number of incoming calls for each detected telephone number when there is no call. Here, “at the time of absence” refers to a case where the receiver does not respond even when the ring tone is played for a preset time or number of times when an incoming call is received. This may be the case when the user does not have a cellular phone at hand, the user is turned off or is in manner mode during a meeting, watching a movie, riding a train, driving a car, or the like. A part of the memory area of the communication memory unit 1515 in FIG. 15 is allocated as the pattern number storage unit 303 and the number of incoming calls storage unit 304, and the number of incoming calls at the time of absence and the pattern number of the ringtone corresponding to the number of incoming calls are shown in FIG. Remembered as shown. If there is an incoming call from the set telephone number when there is no call, the communication control unit 1516 increments and updates the number of incoming calls for the telephone number stored in the incoming call count storage unit 304.

In FIG. 8, the pattern number “1” 303a is applied at the time of the first incoming call according to the number of incoming calls to a specific telephone number set in advance. Pattern number “2” 303b is applied. It shows a setting in which pattern number 3 is applied when the same telephone number is detected for the third time without receiving an incoming call. Specifically, at the time of the first incoming call, the ring tone having the pattern number “1” 303a is reproduced, and the sound data number “1”, the sound data number “2”, and the sound data number “3” in FIG. Will be played. When the second call is received, the ring tone having the pattern number “2” 303b is reproduced, and similarly, the sound data number “1”, the sound data number “2”, and the sound data number “4” in FIG. 2 are reproduced. Will be. When the third incoming call is received, the ring tone having the pattern number “3” 303c is reproduced, and the sound data number “2” in FIG. 2 is reproduced. When the absence is resolved several times, the communication control unit 1516 sends a pattern number corresponding to the number of times to the reproduction timing storage unit 1 of FIG.

  In this case, this mode is activated only for a preset telephone number because it is annoying due to annoying calls such as noisy and persistent solicitations, mischievous calls, silent calls, etc., or fax mistransmission. This is to prevent the operation in this mode with respect to the retry operation, and can inform the user of the urgency and importance of the incoming call when there is a sick person or the like in the family or relatives, for example.

  By using a PCM sound source as a ringtone, it is also possible to reproduce words such as “second call” for a second missed call from a set telephone number. In this way, if a sound for alerting the person is set every time the number of calls increases, even if the first call is not noticed, the number of incoming calls increases, so that the incoming calls can be easily understood and calls can be made. In addition, since the number of incoming calls is known, the urgency and importance of the incoming call can be understood, and excellent usability can be obtained.

  Further, the communication control unit 1516 counts the number of calls in one incoming call of the detected telephone number instead of the number of missed calls, stores the number of calls in the incoming number storage unit 304 and increments and updates it. As such, the program may be changed. In this case, the ring tone can be changed over time in a single incoming call. For example, the first call is called with a gentle sound, and when the number of calls becomes very large, the call is changed to a noisy ringing sound, so that the user can easily notice the incoming call.

  Next, a fourth example of the pattern number selection method will be described as a fourth embodiment with reference to FIGS. 9, 10, 13, and 14. FIG. In the present embodiment, a ring tone is changed by setting a mode according to the sound state of the environment in which the mobile phone is used and selecting a pattern number according to the mode. In FIG. 9 and FIG. 10, a mode for notifying incoming calls when the surroundings are noisy like a normal street or a mode for notifying incoming calls when it is necessary to be quiet during a conference is set. The ring tone is changed by selecting the pattern number according to the mode. In FIGS. 13 and 14, a mode is set according to the level of noise around the mobile phone that is receiving a call, and the ring tone is changed by selecting a pattern number according to the mode. Except for the control program and function of the communication control unit 1516 and the contents of the pattern number table stored in the communication memory unit 1515, the present embodiment is the same as the first embodiment. 9 and 13 are block diagrams showing functional blocks necessary for selecting a pattern number from the state of surrounding sounds. Since the reception unit 401 and the reception unit 601, the ringtone control unit 402 and the ambient noise detection unit 602, the pattern number storage unit 403, and the pattern number storage unit 603 have the same functions, respectively, FIG. I will explain. Referring to the circuit configuration of the mobile phone shown in FIG. 15, the receiving unit 401 that receives a radio signal is a receiving circuit part included in the radio unit 1511 in FIG. 15, and the ring tone control unit 402 is shown in FIG. A communication control unit 1516 sets a mode according to the state of sound around the mobile phone according to a program stored in the communication memory unit 1515, and selects a pattern number according to the mode. The state of the surrounding sound is determined by the sound frequency detected by the microphone 1513, the sound pressure level, the difference in sound pressure level, the duration of a certain sound pressure level, or the duration of a sound in a specific frequency range. The A part of the memory area of the communication memory unit 1515 in FIG. 15 is allocated as the pattern number storage unit 403, and the ring tone pattern number corresponding to the sound state around the mobile phone is stored as shown in FIG. Yes. These correspondences are the same for the reception unit 601, the ambient noise detection unit 602, and the pattern number storage unit 603.

  In the case of FIG. 9 and FIG. 10, the ring tone control unit 402 is for determining whether the surrounding area used is normal, such as a normal street, or whether it is necessary to be quiet, such as during a meeting. The sound pressure level, the difference in sound pressure level, the duration of a certain sound pressure level, or the duration of a sound in a specific frequency range are determined. For example, during a meeting, there is a difference in sound pressure level depending on whether or not speech is being made, and sounds in the frequency range of a human voice are detected intermittently. In the case of a library or the like, sounds in the frequency range of a human voice are detected intermittently, but the sound pressure level is low and the difference in height of the sound pressure level is small. On the other hand, when the surroundings such as streets are noisy, the sound pressure level is large and the difference in the sound pressure level is small, and sounds in a wide frequency range are continuously detected. The ring tone control unit 402 is based on the difference in the sound pressure level, the difference in sound pressure level, the duration of a certain sound pressure level, or the duration of a sound in a specific frequency range, for example. The mode number is determined by judging the environment around the mobile phone, and the pattern number corresponding to the mode number is selected from the pattern numbers stored in the pattern number storage unit 403. In the pattern number storage unit 403, pattern numbers are set according to the setting mode as shown in FIG. The setting mode is mode number “1” if the surroundings are noisy, mode number “2” if you need to be quiet, such as a library, or mode number “3” with your incoming call in your room in mind. Can be set appropriately. Here, pattern numbers “1”, “2”, and “3” are set according to mode numbers “1”, “2”, and “3”, respectively.

  In the case of FIGS. 13 and 14, the pattern number is simply set and stored in the pattern number storage unit 603 corresponding to the volume level of noise around the mobile phone at the time of incoming call. In this case, the ambient noise detection unit 602 determines the volume level of noise around the mobile phone based on the sound pressure level of the sound detected by the microphone 1513. In the pattern number storage unit 603, pattern numbers are set according to the ambient noise level as shown in FIG. For the ambient noise level, for example, the mode number “1” 603a is set as a range in which the setter feels that the sound pressure level range of 60 dB or more is “very loud”, and the sound pressure level range of 59 dB to 40 dB is set to “good”. Mode number “2” 603b is set as a range in which it feels “noisy”, and mode number “3” 603c is set in a range in which a sound pressure level range of 39 dB or less is felt as “no noise”. This range can be freely set according to the individual sense of the individual setter. Thereafter, the communication control unit 1516 sends the pattern number to the reproduction timing storage unit 1 of FIG. 1, and proceeds to the ringing tone creation process.

  Here, in the pattern number corresponding to the mode when the surroundings are noisy, a ringing tone that can be easily distinguished from surrounding sounds and is easy to notice is set in advance. In addition, the ringtone in the mode for setting the incoming call in a quiet scene such as a library should be set as a quiet ringtone that only the user can understand. As a result, the ring tone set by the user in advance according to the surrounding sound conditions at the time of the incoming call is reproduced. In addition, for example, a high-pitched ring tone is set in advance so that the pattern number corresponding to the case where the ambient noise level is felt to be “notably noisy” may be easily noticed. Also, if the ambient noise level feels “no noise”, such as in a library, set a quiet ringtone that can only be understood by you. As a result, ambient noise is automatically detected when a call is received, and a call is made with a ring tone set in advance by the user. As a result, a call can be made with an appropriate ring tone corresponding to the surrounding situation at the time of an incoming call. Also, by increasing the number of mode settings, it is possible to cope with the complexity of the usage situation of mobile phone users.

  The present invention is not limited to the above embodiment, and a ring tone is changed by providing a heat / pressure sensor, a temperature sensor, etc. for detecting that the user has picked up the mobile phone. There may be. When a user has a mobile phone in his hand, there is no need to make a loud ringing tone. Therefore, by installing a thermal sensor that senses the temperature of the person and a pressure sensor that can detect when held by hand, it automatically determines that the person is holding it and controls it to reduce the ringtone. Also good. Also, if a pressure sensor and temperature sensor that can be detected by hand are combined, and a temperature of 25 degrees Celsius or higher is detected even when not being held by hand, the temperature is high, that is, a hot place or a hot season Judgment may be made to make the ringtone cool and soothe the user's mind. In addition, a function may be added in which a light ringing tone is produced when a mobile phone is in a bag by combining an optical sensor, and when the mobile phone is taken out of the bag, the outside light can be sensed and turned into a quiet ringing tone. In recent years, the use of mobile phones in cars has been punished by law. Therefore, by adding a function to detect that the mobile phone is in the car with an acceleration sensor, it automatically determines that it is driving and automatically reduces the ringtone so that the user does not know, Alternatively, the missed call count mode of the third embodiment may be set. The above modification can be implemented by using the output of the thermal sensor, pressure sensor, temperature sensor, optical sensor, or acceleration sensor instead of the output of the microphone 1513 which is the ambient noise sensor in the fourth embodiment. .

  Next, a fifth example of a pattern number selection method will be described as a fifth embodiment with reference to FIGS.

  In the present embodiment, the ring tone is changed by selecting a pattern number from the remaining battery level of the mobile phone. Except for the control program and function of the communication control unit 1516 and the contents of the pattern number table stored in the communication memory unit 1515, the present embodiment is the same as the first embodiment. FIG. 11 is a block diagram showing functional blocks necessary for selecting a pattern number from the remaining battery level. The battery function 504 is a part that supplies power to a mobile phone or stores power charged from a charger (not shown), and transmits a radio signal. The receiving unit 501 for receiving is a receiving circuit part included in the wireless unit 1511 in FIG. 15, and the remaining battery level detecting unit 502 is the communication control unit 1516 in FIG. 15, according to the program stored in the communication memory unit 1515. This is a part for detecting the current charged battery capacity from the battery function 504 upon receipt of information indicating that there is an incoming call from the receiving unit 501. A part of the memory area of the communication memory unit 1515 in FIG. 15 is allocated as the pattern number storage unit 503, and the pattern number of the ringing tone corresponding to the remaining battery level is stored as shown in FIG. The pattern number storage unit 503 sets and stores a pattern number according to the remaining battery level obtained by the remaining battery level detection unit 502 as shown in FIG. 12. For example, when the remaining battery level is sufficient The pattern number “1” 503a is applied, the pattern number “2” 503b is applied when the remaining amount of memory is two on the display, and the pattern number “3” is applied when charging is necessary. It is set so that the ringing tone 503c is reproduced. After selecting the pattern number corresponding to the remaining battery level, the communication control unit 1516 sends the pattern number to the reproduction timing storage unit 1 in FIG. 1, and proceeds to the ringing tone creation process.

  When an incoming call is made in this way, the remaining battery level can be roughly grasped simply by listening to the ring tone. As a result, since the remaining battery level can be confirmed before the call, it is possible to shorten the call time or to request communication again after charging, thereby preventing inadvertent call disconnection during the call. (In the past, the battery capacity was lost during a call and the call was cut off unexpectedly.) Also, by setting the ringtone for charging to be easily noticed by the user, the need for charging can be carried. It is also possible to make the telephone user strongly recognize. Further, instead of the remaining battery level, the ring tone may be changed according to the field strength of the antenna, the remaining number of addresses in the address book, the accumulated call time, and the like. As a result, the user can additionally grasp information such as the electric field strength of the antenna, the remaining memory of the address book, and the accumulated call time when receiving an incoming call.

  In the above embodiment, the analysis / synthesis coding method (FM sound source method) is mainly used as the ringtone, so that the memory capacity can be relatively small, and sounds such as musical instruments can be reproduced abundantly. be able to. Along with this, by using a waveform encoding method (PCM sound source method) such as a sound source method directly recorded from a microphone or the like, the effect of distinguishing the ring tone of one's mobile phone from the ring tone of another's mobile phone Is obtained. At this time, a large amount of data is required to hold PCM sound source data, but the additional use of PCM sound source data provides an effect of reducing the memory capacity.

  In addition, the caller can be recognized in advance by changing the ring tone from the caller's telephone number. As a result, it is possible to obtain an effect that a caller who appears to be an important matter just by listening to a ringtone can immediately appear or an unnecessary incoming call can be put on hold.

  Further, by changing the ring tone according to the current time and the remaining battery level, it is possible to obtain additional information such as grasping the current rough time and knowing the remaining battery level simply by listening to the ring tone. In addition, by changing the ring tone according to the number of calls from a specific person, the ring tone control mode, or the surrounding noise level, an effect that the owner can easily recognize the incoming call can be obtained.
