[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit block diagram of a mobile phone device according to the present invention.
[0012]
An antenna 1 is connected to a CPU (Central Processor Unit) 3 via a wireless unit 2. Further, the input side of the sender information detection circuit 4 is connected to the radio unit 2, and the output side of the sender information detection circuit 4 is connected to the CPU 3. The CPU 3 is connected to a key input unit 5, a ROM (Read Only Memory) 6, a RAM (Random Access Memory) 7, a driver circuit 8, a nonvolatile memory 10, and a reproduction circuit 11. Further, the display device 9 is connected to the driver circuit 8, the reproduction circuit 11 is connected to the driver circuit 12, and the speaker 13 is connected to the driver circuit 12.
[0013]
The incoming call notification operation of the mobile phone having such a configuration will be described below. The CPU 3 comprehensively controls the entire mobile phone device using the RAM 7 that stores control data according to a program stored in the ROM 6.
[0014]
The non-volatile memory 10 stores a data table in which information of a registration number, a selection number, a caller's telephone number, and information of use / non-use in a normal incoming call is associated with each of a plurality of ring tone data. FIG. 2 shows an example of a data table stored in the nonvolatile memory 10. The user can edit the selection number or the like by operating the key input unit 5 with reference to the display on the display device 9.
[0015]
The wireless unit 2 receives a wireless signal via the antenna 1, demodulates the wireless signal to generate a received signal, and sends the received signal to the CPU 3 and the sender information detecting circuit 4. The sender information detection circuit 4 detects sender information based on the reception signal generated by the wireless unit 2 and sends the detection result to the CPU 3. The CPU 3 determines whether there is an incoming call based on a reception signal generated by the wireless unit 2. If there is an incoming call as a result of the determination, the CPU 3 displays the detection result of the sender information detection circuit 4 on the display device 9, accesses the nonvolatile memory 10, and refers to the data table stored in the nonvolatile memory 10. Then, the ring tone data to be sent from the CPU 3 to the reproduction circuit 11 is determined. When the non-volatile memory 10 stores the data table of FIG. 2, if the caller telephone number is other than “123456789” or “98765321”, the call is a normal call, and the CPU 3 sends the ring tone data D3 to the reproduction circuit 11. If the caller telephone number is "123456789", the CPU 3 sends the ring tone data D2 to the reproduction circuit 11, and if the caller telephone number is "98765321", the CPU 3 sends the ring tone data D7 to the reproduction circuit 11. I do.
[0016]
The reproduction circuit 11 reproduces the ringtone data transmitted from the CPU 3 and transmits the reproduced data (audio signal) to the driver circuit 12. The driver circuit 12 amplifies the audio signal and sends it to the speaker 13. Thereby, the speaker 13 emits a ringtone and notifies the user of the incoming call.
[0017]
Next, FIG. 3 shows a configuration of a power supply system of the mobile phone device shown in FIG. In FIG. 3, the same parts as those in FIG. 1 are denoted by the same reference numerals.
[0018]
The input terminal 14 is connected to the anode of the diode D1. The cathode of the diode D1 is connected to the input side of the regulator 18 and the input side of the regulator 19. The output side of the regulator 18 is connected to a circuit 20 (hereinafter, referred to as “reproducing circuit 20”) including the wireless unit 2, the sender information detecting circuit 4, the driver circuit 8, the display device 9, the reproducing circuit 11, and the driver circuit 12. The output side of the regulator 19 is connected to the CPU 3.
[0019]
The input terminal 14 is also connected to the anode of the diode D2. The cathode of the diode D2 is connected to the input side of the charging circuit 15. The output side of the charging circuit 15 is connected to the anode of the diode D3 via the current detector 16. The cathode of the diode D3 is connected to the positive electrode of the rechargeable battery 17 and the anode of the diode D4. The negative side of the rechargeable battery 17 is grounded, and the cathode of the diode D4 is connected to the input side of the regulator 18 and the input side of the regulator 19.
[0020]
Further, the input terminal 14 is also connected to one end of the resistor R1. The other end of the resistor R1 is grounded via a resistor R2.
[0021]
Then, the CPU 3 is connected to the connection node between the resistors R1 and R2, the current detector 16, the reproduction circuit 20, and the like.
[0022]
The operation of the power supply system circuit having such a configuration will be described. When an AC adapter (not shown) for outputting a predetermined DC voltage is connected to the input terminal 14, a predetermined DC voltage output from the AC adapter (not shown) is supplied via the input terminal 14 and the diode D1. It is supplied to regulators 18 and 19. Then, the output voltage of the regulator 18 is supplied to the reproduction circuit 20 and the like, and the output voltage of the regulator 19 is supplied to the CPU 3. Thereby, the CPU 3 and the reproduction circuit 20 can operate.
[0023]
Further, a predetermined DC voltage output from an AC adapter (not shown) is supplied to the charging circuit 15 via the input terminal 14 and the diode D2. The charging circuit 15 charges the rechargeable battery 17 via the current detector 16 and the diode D3. When an AC adapter (not shown) is connected to the input terminal 14, the rechargeable battery 17 does not discharge because the cathode potential of the diode D4 is higher than the anode potential of the diode D4.
[0024]
The current detector 16 detects the current flowing from the charging circuit 15 to the rechargeable battery 17, so that the start of charging and the full charge can be detected. The start of charging is when the current starts flowing from the charging circuit 15 to the rechargeable battery 17, and the full charge is when the current starts flowing from the charging circuit 15 to the rechargeable battery 17 and the current decreases to a predetermined value. is there. Since the detection result of the current detector 16 is sent to the CPU 3, the CPU 3 can recognize the start of charging and the full charge. One embodiment of the current detector 16 includes a configuration in which a current is detected by using a shunt resistor and a potential difference between both ends of the shunt resistor.
[0025]
Since the voltage detection circuit including the resistors R1 and R2 detects the voltage applied to the input terminal 14, it can detect whether or not an AC adapter (not shown) is connected to the input terminal 14. If the voltage detected by the voltage detection circuit including the resistors R1 and R2 matches the value of the predetermined DC voltage output from the AC adapter (not shown), the input terminal 14 is connected to the AC adapter (not shown). Is connected. On the other hand, when the voltage detected by the voltage detection circuit including the resistors R1 and R2 does not match the value of the predetermined DC voltage output from the AC adapter, an AC adapter (not shown) is connected to the input terminal 14. Not connected.
[0026]
Hereinafter, two embodiments will be described for the reproduction of ring tone data other than the incoming call, which is a characteristic part of the present invention.
[0027]
First, a description will be given of a first embodiment of reproduction of ringtone data other than the time of an incoming call. In the first embodiment, the CPU 3 provided in the mobile phone of FIG. 1 has a timer function. Then, the user can set the time of the timer and start the timer by operating the key input unit 5 with reference to the display on the display device 9.
[0028]
The CPU 3 starts the timer by a key operation of the user, and at the same time, accesses the non-volatile memory 10 and determines ring tone data to be transmitted from the CPU 3 to the reproduction circuit 11 by referring to the data table stored in the non-volatile memory 10. Then, the reproduction circuit 11 reproduces the ringtone data transmitted from the CPU 3 and transmits the reproduced data (audio signal) to the driver circuit 12. The driver circuit 12 amplifies the audio signal and sends it to the speaker 13. Thereby, the speaker 13 emits a ringtone. Note that which ring tone data is reproduced in which order will be described later.
[0029]
Thereafter, the CPU 3 monitors the remaining time of the timer, and when the remaining time of the timer becomes zero, terminates the reproduction of the ringtone data. This allows the user to listen to the ringtone while the timer is running, even if there is no incoming call. For example, it is possible to sleep while listening to the ringtone when going to bed. As described above, the portable telephone device according to the present invention can sufficiently utilize the high sound quality of the ringtone.
[0030]
Next, a description will be given of a second embodiment of the reproduction of the ring tone data other than the time of the incoming call. In the second embodiment, as in the first embodiment, the CPU 3 provided in the mobile phone of FIG. 1 has a timer function.
[0031]
The CPU 3 recognizes the start of charging of the rechargeable battery 17 based on the output signal of the current detector 16. Then, the CPU 3 accesses the nonvolatile memory 10 at the same time when the charging of the rechargeable battery 17 is started, and determines ringtone data to be transmitted from the CPU 3 to the reproduction circuit 11 with reference to the data table stored in the nonvolatile memory 10. Then, the reproduction circuit 11 reproduces the ringtone data transmitted from the CPU 3 and transmits the reproduced data (audio signal) to the driver circuit 12. The driver circuit 12 amplifies the audio signal and sends it to the speaker 13. Thereby, the speaker 13 emits a ringtone. Note that which ring tone data is reproduced in which order will be described later.
[0032]
The user can set the time of the timer and start the timer by operating the key input unit 5 with reference to the display on the display device 9. It is preferable that the timer can be set before or after charging of the rechargeable battery 17 is started. When the time setting of the timer is performed before the charging of the rechargeable battery 17 is started, for example, the timer may be automatically activated at the same time as the charging of the rechargeable battery 17 is started. On the other hand, when the time setting of the timer is performed after the charging of the rechargeable battery 17 is started, for example, the timer may be automatically activated at the same time as the completion of the time setting of the timer.
[0033]
After starting the reproduction of the ring tone data, the CPU 3 monitors the full charge of the rechargeable battery 17 based on the remaining time of the timer and the output signal of the current detector 16. Then, when the timer remaining time becomes zero or the rechargeable battery 17 is fully charged, the reproduction of the ringtone data is terminated. In the second embodiment, since the ring tone data is reproduced only during charging, the consumption of the rechargeable battery 17 due to the reproduction of the ring tone data other than at the time of the incoming call can be reduced.
[0034]
Subsequently, which ring tone data is reproduced in which order in the first embodiment and the second embodiment will be described. Here, three reproduction patterns will be described. In the first reproduction pattern, one ring tone data is repeatedly reproduced. The second reproduction pattern sequentially reproduces a plurality of ring tone data in a predetermined order. The third reproduction pattern reproduces a plurality of ring tone data irregularly.
[0035]
FIG. 4 shows an operation flow of the CPU 3 when the first reproduction pattern is performed. In the first reproduction pattern, the ring tone data of the selection number 1 is reproduced (step S10), and when the reproduction is completed, the reproduction of the ring tone data of the selection number 1 is started again. When the nonvolatile memory 10 stores the data table shown in FIG. 2, the ringtone data D3 is repeatedly reproduced.
[0036]
FIG. 5 shows an operation flow of the CPU 3 when the second reproduction pattern is performed. In the second reproduction pattern, first, ring tone data corresponding to the same selection number as the variable N is reproduced (step S110). Note that the variable N is set to “1” at the time of factory shipment. Subsequently, the CPU 3 sets a value obtained by adding 1 to the variable N as a new variable N (step S120), and determines whether the variable N is equal to or less than the maximum value of the selection number (step S130). If the variable N is equal to or less than the maximum value of the selection number (Yes in step S130), the CPU 3 proceeds to step S110 without changing the variable N determined in step S120. On the other hand, if the variable N is not equal to or less than the maximum value of the selection number (No in step S130), the CPU 3 changes the variable N to 1 (step S140), and proceeds to step S110. When the nonvolatile memory 10 stores the data table shown in FIG. 2, the ring tone data D3 → the ring tone data D2 → the ring tone data D7 → the ring tone data D1 → the ring tone data D9 → the ring tone data D3 → the ring tone. .. Are repeatedly reproduced in the order of data D2 →.
[0037]
FIG. 6 shows an operation flow of the CPU 3 when the third reproduction pattern is performed. In the third reproduction pattern, first, the CPU 3 generates a random integer (hereinafter referred to as a random number R) based on a random number in a range from "1" to "the maximum value of the selection number" (step S210). Next, the CPU 3 reproduces the ring tone data corresponding to the selected number having the same value as the random number R (step 220), and proceeds to step S210. When the non-volatile memory 10 stores the data table shown in FIG. 2, the ring tone data is reproduced by repeatedly selecting the ring tone data D1, D2, D3, D7, and D9 at random. Will be.
[0038]
In the first embodiment and the second embodiment described above, the ring tone data at the time of the incoming call is determined so that the user can easily determine the reproduction of the ring tone data at the time of the incoming call and the reproduction of the ring tone data at the time other than the incoming call. It is desirable that the speaker volume for reproduction and the speaker volume for reproduction of ring tone data other than at the time of an incoming call can be set separately. In this case, it is preferable that the volume of the speaker for reproducing the ring tone data other than the time of the incoming call is lower than the volume of the speaker for reproducing the ring tone data when the incoming call is received.
[0039]
In the first and second embodiments described above, the ring tone data used at the time of the incoming call is used other than at the time of the incoming call, but the reproduction of the ring tone data at the time of the incoming call and the reproduction of the ring tone data at the time other than the incoming call are performed by the user. The ring tone data used at the time of the incoming call may not be used except at the time of the incoming call so that can be easily determined. That is, it may be prohibited that the selection number and the caller's telephone number or the setting of the use of the normal incoming call overlap with one ring tone data.
[0040]
In addition, the mobile phone device can normally set a silent mode (manner mode) in which an incoming call is notified by vibration instead of being notified by a ring tone. In the portable telephone device according to the present invention, it is desirable to prohibit the reproduction of ring tone data other than the incoming call in the silent mode (manner mode).
[0041]
Further, in the above-described embodiment, the reproduction circuit is provided separately from the CPU in order to improve the sound quality of the ringtone. However, the present invention is not limited to this, and the reproduction circuit is not provided. A configuration for performing a process of reproducing ringtone data may be employed.
[0042]
In the above-described second embodiment, the start of charging of the rechargeable battery 17 is detected based on the detection result of the current detector 16, but the input terminal is determined based on the signal output from the voltage detection circuit including the resistors R1 and R2. When it is recognized that the battery 14 and the AC adapter (not shown) are connected, it may be considered that the charging of the rechargeable battery 17 has been started.
[0043]
When the rechargeable battery 17 is not fully charged, charging starts when the input terminal 14 is connected to an AC adapter (not shown). When the rechargeable battery 17 is fully charged, an input from the AC adapter (not shown) is performed. Since it is not connected to the terminal 14, a voltage detection circuit composed of the resistor R1 and the resistor R2 can be used as the charging start means.
[0044]
However, it is conceivable that the user accidentally connects an AC adapter (not shown) to the input terminal 14 when the rechargeable battery 17 is fully charged. When the rechargeable battery 17 is fully charged, the charging of the rechargeable battery 17 is not started even if the input terminal 14 is connected to an AC adapter (not shown). However, even in such a case, the ring tone data is reproduced. . At this time, since the CPU 3 and the reproduction circuit 20 are operated by the output power of the AC adapter (not shown), the consumption of the rechargeable battery 17 due to the reproduction of the ring tone data is small.
[0045]
In the second embodiment described above, the reproduction of the ringtone data is stopped when the remaining time of the timer becomes zero or when the rechargeable battery 17 is fully charged, but when the remaining time of the timer becomes zero or The reproduction of the ring tone data may be stopped when the connection between the input terminal 14 and the AC adapter (not shown) is released. In this case, the CPU 3 disconnects the input terminal 14 from the AC adapter (not shown) based on a signal output from the voltage detection circuit including the resistors R1 and R2 when the timer remaining time becomes zero. When recognizing that the ringing has been performed, the reproduction of the ringtone data is stopped. Even in such a case, the CPU 3 and the reproduction unit are not charged during the period from when the rechargeable battery 17 is fully charged to when the connection between the input terminal 14 and the AC adapter (not shown) is released and when the remaining time of the timer is not zero. Since the circuit 20 and the like are operated by the output power of the AC adapter (not shown), the consumption of the rechargeable battery 17 due to the reproduction of the ring tone data is small.
[0046]
In addition, in the second embodiment described above, the user operates the key input unit 5 with reference to the display device 9 so as to cope with a case where the user does not want to listen to the ring tone during charging. Even if there is, a function that can be set so as not to reproduce the ringtone data may be added.
[0047]
【The invention's effect】
According to the present invention, the telephone device reads out the ring tone data from the storage unit by starting the operation of the time limit unit, starts the reproduction by starting the operation of the time limit unit, And reproduction means for reproducing the ring tone data during the operation of, so that the ring tone data can be reproduced and listened to at any time other than at the time of an incoming call. As a result, the high sound quality of the ringtone can be fully utilized.
[0048]
Further, according to the present invention, the telephone device has a storage unit for storing ringtone data in advance, a charging start detecting unit for detecting a start of charging of the built-in rechargeable battery, and a charging start detecting unit that detects the start of charging. Since there is provided a reproducing means for reading out the ring tone data from the storage means and starting reproduction, the ring tone data can be reproduced and listened to during charging even if there is no incoming call. As a result, the high sound quality of the ringtone can be fully utilized. Also, since the ring tone data is reproduced during charging, it is possible to notify that charging is in progress, and it is possible to eliminate the possibility that the consumption of the built-in rechargeable battery is accelerated by the reproduction of the ring tone data other than the time of the incoming call. .
[0049]
Further, according to the present invention, the telephone device stores a ring tone data in advance, a time limiter, a charge start detector that detects the start of charging of the built-in rechargeable battery, and detects a full charge of the built-in rechargeable battery. When full charge detection means and the start of operation of the time limit means or the start of charge is detected by the charge start detection means, the storage means reads out the ringtone data and starts reproduction, and ends the operation of the time limit means or And reproduction means for stopping the reproduction of the ring tone data when the full charge is detected by the full charge detection means, so that the reproduction of the ring tone data can be automatically stopped.
[0050]
Further, according to the present invention, in addition to the above-described configuration, when an incoming call is received when the reproducing unit is reproducing the ringtone data based on the time limit unit or the charging start detecting unit, Since the notifying means for notifying the incoming call by changing the reproduction volume of the ring tone data is provided, the user can determine that there is an incoming call even while the ring tone data is being reproduced.
