[Problems to be solved by the invention]
In a mobile phone, if there is an incoming call, a ring tone is generated to notify the user of the incoming call. When the mobile phone is not in use (standby), the mobile phone is usually put in the pocket or bag of the user's clothes, and the volume of the ringtone should be assured to the user, assuming the above case. It is set large enough to be able to notify you of an incoming call. Further, in a foldable mobile phone, when the ring tone generating means is disposed inside the main body with the main body closed, it is necessary to generate a ring tone at a higher volume. In any case, the volume of the ring tone that sounds when the main body is opened is too large, and there is a possibility that the user or a nearby person may be excessively uncomfortable.
[0005]
Therefore, in the conventional foldable mobile phone, when it is detected that the main body is opened after an incoming call, the ring tone is stopped or the volume is reduced, but the incoming call is received with the main body opened. Is not taken into account, and in this case a large volume ringtone will suddenly sound, despite the assumption that the user is performing some operation, There is a problem that this may cause excessive discomfort to the person.
[0006]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and a foldable mobile phone that does not suddenly emit a large volume ringtone when an incoming call is received with the main body opened. What you get.
[0007]
[Means for Solving the Problems]
In the foldable mobile phone according to the present invention, a foldable main body, open / close detection means for detecting opening / closing of the main body, a speaker for generating a ring tone for notifying an incoming call, and a state in which the main body is closed When an incoming call is received, the ring tone sounds at a first volume, and when an incoming call arrives with the main body open, the ring tone sounds at a second volume lower than the first volume. And a control circuit for performing the control.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
A foldable mobile phone according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram. In FIG. 1, the open / close state of the main body of the mobile phone is detected by an open / close detection circuit 1, and the open / close state of the main body is determined by a signal from the open / close detection circuit 1 and control of each operation in the mobile phone. , And the time information is managed by the control circuit 2. Various sounds such as ringtones are held in the sound source circuit 3, and the volume of the sound source output from the sound source circuit 3 is adjusted by a gain adjustment circuit 4 controlled by the control circuit 2. The sound electric signal output from the gain adjustment circuit 4 is converted into sound by the speaker 6 via the amplification circuit 5.
[0009]
FIG. 2 shows a state where the mobile phone body is opened, and FIG. 3 shows a state where the mobile phone body is closed. In FIGS. 2 and 3, a magnetic sensor element 13 and a speaker 6 are provided on the upper surface of the first main body case 11. A magnet 14 corresponding to the magnetic sensor element 13 is provided on the upper surface of the second main body case 12. When the mobile phone body is closed, the magnetic force from the magnet 14 is recognized and switched by the magnetic sensor element 13 provided at the position where the magnets 14 overlap each other, so that opening and closing can be detected. Therefore, the magnetic sensor element 13 and the magnet 14 constitute the opening / closing detection circuit 1 for detecting the opening / closing of the main body.
[0010]
FIG. 4 is a flowchart showing the operation from the incoming call to the call state. If there is an incoming call to the mobile phone in the standby state (step S21), first, the control circuit 2 determines the open / closed state of the mobile phone body based on the signal from the open / close detection circuit 1 (step S22).
[0011]
If it is determined in step S22 that the main body is closed, the control circuit 2 controls the gain adjustment circuit 4 to determine the volume of the ringtone (first volume) that can reliably notify the user of the incoming call. (Step 32). Next, the tone generator circuit 3 is started (step 33), and the ringing tone is started to sound at the first volume from the speaker 6 via the amplifier circuit 5 (step 34). Thereafter, off-hook is determined (step S35), and if it is off-hook, the ring tone is stopped (step S30), and a transition is made to a call state (step S31). The off-hook is determined by, for example, whether or not a call button of the mobile phone is pressed. Further, the first volume is set to be higher when the speaker 6 that generates a ringtone is arranged inside the main body than when it is arranged outside the main body.
[0012]
If it is determined in step S22 that the main body is open, the control circuit 2 controls the gain adjustment circuit 4 so that the volume of the ring tone is lower than the first volume (a second volume). (Step 23). Next, the tone generator circuit 3 is started (step 24), and the ringing tone is started to sound at the second volume from the speaker 6 via the amplifier circuit 5 (step 25). Thereafter, off-hook is determined (step S26), and if it is off-hook, the ring tone is stopped (step S30), and a transition is made to a call state (step S31).
[0013]
If it is not off-hook in step 26, the ringing time of the ring tone is determined by the control circuit 2 (step S27). If a certain time has elapsed, the gain adjustment circuit 4 is controlled from the control circuit 2 and the ringing is being performed. Is controlled so that the volume of the ringtone of the second tone is changed from the second volume to the first volume (step S28), and then off-hook is determined (step S29). ), And shift to a call state (step S31). If the predetermined time has not elapsed in step 27, the process returns to step 26 again.
[0014]
As described above, in the foldable mobile phone that also functions as the speaker and the ringer, the open / close state of the main body when the incoming call is received in the standby state is determined. By lowering the volume of the ring tone compared to when there is an incoming call with the phone closed, the ring tone does not suddenly sound loud when the user opens the main unit and performs any operation. You can do so.
[0015]
Embodiment 2 FIG.
FIG. 5 is a flowchart showing the operation of the foldable mobile phone according to the second embodiment from the incoming call to the call state. Note that the block diagram and the main body configuration are the same as those in FIGS. 1 and 2 of the first embodiment. If there is an incoming call to the mobile phone in the standby state (step S41), first, the control circuit 2 determines the open / close state of the main body of the mobile phone based on a signal from the open / close detection circuit 1 (step S42).
[0016]
If it is determined in step S42 that the main body is closed, the control circuit 2 controls the gain adjustment circuit 4 by the same operation as in the first embodiment, so that the user can be reliably notified of the incoming call. Control is performed so as to be the volume of the ringtone (first volume) (step S54). Next, the tone generator circuit 3 is started (step S55), and the ringing tone is started to sound at the first volume from the speaker 6 via the amplifier circuit 5 (step S56). Thereafter, off-hook is determined (step S57), and if it is off-hook, the ring tone is stopped (step S52), and a transition is made to a call state (step S53).
[0017]
If it is determined in step S42 that the main body is open, the control circuit 2 controls the gain adjustment circuit 4 to control the volume of the ringtone to be the minimum gain (step S43). Next, the sound source circuit 3 is started (step S44), and ringing of a ring tone is started at the minimum gain volume from the speaker 6 via the amplifier circuit 5 (step S45). Thereafter, off-hook is determined (step S46), and if it is off-hook, the ring tone is stopped with the minimum gain (step S52), and the state shifts to a call state (step S53).
[0018]
If it is not off-hook in step S46, the control circuit 2 determines the elapse of a unit time for increasing the volume gradually (stepwise) (step S47), and if the unit time for increasing the volume has elapsed, the control circuit 2 2 to control the gain adjustment circuit 4 to increase the volume by the amount corresponding to the passage of time (step S48). If the time to increase the volume has not reached, the volume is left as it is and the next step S49. Move to. For example, if the unit time for increasing the volume is set to 5 seconds, the ringtone sounds at the minimum gain for 5 seconds from the start of ringing, the next 5 seconds sounds at a level one step higher than the minimum gain, and the next 5 seconds. If there is no off-hook in step S46, such as ringing at a volume two steps higher than the minimum gain for seconds, the volume of the ringtone is increased stepwise every 5 seconds.
[0019]
Further, the control circuit 2 also determines the total ringing time from the start of ringing of the ringtone (step S49), and when a certain time has elapsed, the control circuit 2 controls the gain adjustment circuit 4 and in step S42, Control is performed so as to have the same first sound volume as when closed (step S50). Thereafter, off-hook is determined (step S51), and if it is off-hook, the ring tone is stopped (step S52), and a transition is made to a call state (step S53). If the predetermined time has not elapsed in step S49, the process returns to step S46. However, if control for increasing the volume is performed in step S48, off-hook is performed when the process returns to step S46. If not, the ringtone is stopped at the increased volume instead of the minimum gain (step S52), and the state shifts to a call state (step S53).
[0020]
As described above, in a foldable mobile phone that also functions as a speaker and a ringer, the open / close state of the main body when a call is received in a standby state is determined. By starting the ring tone from the gain and gradually increasing the volume of the ring tone over time, the ring tone suddenly becomes loud when the user opens the main unit and performs some operation. Ringing can be prevented, and the user can be reliably notified of the incoming call.
[0021]

If it is determined in step S62 that the main body is closed, the control circuit 2 controls the gain adjustment circuit 4 to determine the volume of the ring tone (first volume) that can reliably notify the user of the incoming call. (Step S75). Next, a predetermined ringtone (first seed sound) is set in the sound source circuit 3 and started (step S76). Usually, the first type sound is set to have a high sound pressure level so that the user can easily hear it as a ring tone. Next, the ringing tone starts to sound at the first volume and the first type tone from the speaker 6 via the amplifier circuit 5 (step S77). Thereafter, off-hook is determined (step S78), and if it is off-hook, the ring tone is stopped (step S73), and a transition is made to a call state (step S74).
[0023]
If it is determined in step S62 that the main body is open, the control circuit 2 controls the gain adjustment circuit 4 so that the volume of the ringtone is lower than the first volume (a second volume). (Step S63). Next, a sound or voice (second type sound) different from the first type sound and having a lower sound pressure level than the first type sound is set and started as the ring tone in the sound source circuit 3 (step S64), and the amplification circuit is started. The ringing tone starts to sound at the second volume and the second seed sound from the speaker 6 via the speaker 5 (step S65). Thereafter, off-hook is determined (step S66), and if it is off-hook, the ring tone is stopped (step S73), and a transition is made to a call state (step S74).
[0024]
If it is not off-hook in step S66, the ringing time of the ring tone is determined by the control circuit 2 (step S67). If a predetermined time has elapsed, the second seed tone set in the tone generator 3 is set. The setting is stopped (step S68). Next, the control circuit 2 controls the gain adjustment circuit 4 to control the volume of the ringing tone during ringing from the second volume to the first volume (step S69). The first seed sound is set and started (step S70). Next, the ringing tone starts to sound at the first volume and the first type tone from the speaker 6 via the amplifier circuit 5 (step S71). Thereafter, off-hook is determined (step S72), and if it is off-hook, the ring tone is stopped (step S73), and a transition is made to a call state (step S74). If the predetermined time has not elapsed in step S67, the process returns to step 66 again.
[0025]
As described above, in the foldable mobile phone that also functions as the speaker and the ringer, the open / close state of the main body when the incoming call is received in the standby state is determined. When the user opens the main unit and performs some operation by lowering the volume of the ringtone and changing the sound quality (lowering the sound pressure level) compared to when there is an incoming call with the closed It is possible to prevent sudden ringing of a large volume and a high sound pressure level.
[0026]
