Description

  The present invention relates to audio output control of a portable mobile radio telephone apparatus.

  Portable mobile radiotelephone devices (hereinafter referred to as mobile phones) are widely used. When the mobile phone receives the call, the mobile phone transmits a call voice. The user listens to the calling voice, performs a hook-off operation, and starts a call.

  There is also known a mobile phone having a speakerphone function for performing a call using a speaker suitable for listening to sound at a distance farther than a normal call receiver. If such a function is used, a hands-free call can be performed. With such a function, it is possible to make a call with three or more people, and it is often used particularly in a sudden conference call.

  The following is a reference technique related to voice control of the mobile terminal device.

  By the way, depending on the situation, the user may not notice the calling voice. For example, since the user is lightly dressed in midsummer, there are many cases where there is no pocket for holding a mobile phone, and there are many users who become trapped. In such a case, it is difficult for the user to notice the ring tone. Also, when a user puts a mobile phone in a jacket pocket or the like in the middle of winter, the clothes are thick and often the user does not notice the ringtone. One solution is to vibrate the vibrator, but in the case of a pocket of a bag or thick jacket, it is often not even noticeable.

  On the other hand, in a telephone call using a speakerphone, there are many scenes that need to be used under noise when used outdoors such as at a construction site. In such a situation, it may be difficult to hear the sound even if a speakerphone is used.

  The background of these problems is that it is difficult to mount a large-volume amplifier or speaker because the mobile phone is required to have excellent portability.

  In relation to the above problem, in one aspect of the present invention, the portable mobile radiotelephone device includes a speaker that outputs a ring tone at a preset volume when a telephone call is received, and a voice of the call. And a microphone that inputs the voice of the call from the user, and an additional incoming call by the receiver when a predetermined time set based on the user's input operation has passed without receiving an off-hook while receiving the call A ring tone control unit that performs ring tone addition control for outputting a sound.

  According to the present invention, there is provided a technique that can compensate for a lack of ringing tone of a mobile phone.

FIG. 1A shows the front side of a mobile phone. FIG. 1B shows the back side of the mobile phone. FIG. 2 is a block diagram showing a partial configuration of the mobile phone. FIG. 3 is a flowchart showing ringtone addition control. FIG. 4 is a flowchart showing control of the speakerphone during noise. FIG. 5 shows functional blocks of the mobile phone.

  1A and 1B are image diagrams of a mobile phone according to an embodiment of the present invention. FIG. 1A shows the front side, that is, the side that faces the user's face during a normal call. FIG. 1B shows the back side.

  The mobile phone 10 includes a receiver 2 and a microphone 5 for normal calls on the front side. The mobile phone 10 further includes a speaker 1 that outputs a ringtone. In the example of FIG. 1B, the speaker 1 is disposed on the back side, but may be disposed on the front side.

  FIG. 2 is a block diagram showing a partial configuration of the mobile phone in the present embodiment. The cellular phone 10 includes a speaker amplifier 3 for controlling the volume of the sound output from the speaker 1 by amplifying the sound signal input to the speaker 1. The cellular phone 10 further includes a receiver amplifier 4 that controls the volume of the sound output from the receiver 2 by amplifying the sound signal input to the receiver 2. The LSI 5 controls the speaker amplifier 3, the receiver amplifier 4 and the microphone 5.

  The LSI 6 sets the gain of the speaker amplifier 3 in response to a user input operation on the input device of the mobile phone 10. The user can set the gain of the speaker 1 to a desired value among several stages by an input operation.

  There are two modes for setting the gain of the receiver amplifier 4. In the first mode, the receiver amplifier 4 is set to the first gain. The user can set the first gain to a desired value among several stages by an input operation. In the second mode, the receiver amplifier 4 is set to a second gain that is greater than the first gain. The second gain is preferably the maximum gain of the receiver amplifier 4.

  The LSI 6 switches the gain setting of the speaker amplifier 3 to the maximum volume when the user does not notice the ringtone even if the ringing is performed for a predetermined time, and further sets the receiver amplifier 4 to the second mode (maximum). By driving at a gain, the receiver 2 also rings a ringtone at the same time. This action increases the volume of the ringtone, allowing the user to notice the ringtone even when carrying the mobile phone in a bag or thick jacket pocket etc. It becomes.

  Next, the operation of the mobile phone 10 will be described in more detail with reference to the flowchart of FIG. FIG. 5 shows functional blocks of the mobile phone 10 realized by the LSI 6 executing a program stored in the storage device.

  The user sets the volume of the speaker 1 and the receiver 2 in advance. The gain setting unit 12 stores the gain of the speaker amplifier 3 and the gains of the first mode and the second mode of the receiver amplifier 4 based on the value input by the user. From the viewpoint of easy understanding of the operation, it is desirable that the gain of the second mode of the receiver amplifier 4 is set to the maximum in advance without any user input operation.

  When there is an incoming call to the mobile phone (S1), the LSI 6 drives the speaker amplifier 3 with a gain set in advance by the user to cause the speaker 1 to ring (S2). If the user notices an incoming call at this time and there is an off-hook operation (S3 Yes), the speaker amplifier 3 is turned off (S4). In this case, the gain setting unit 12 sets the receiver amplifier 4 to the first mode gain setting. The LSI drives the receiver amplifier 4 in the first mode (S5), and drives the microphone 5 to enter a call state (S6).

  If the user does not notice even if the speaker 1 outputs a ring tone, no off-hook operation is performed (No in S3). When a predetermined time set in advance by a user operation on the input device has passed without receiving an off-hook operation while receiving a call (S7), the ring tone control unit 11 performs ring tone addition control for increasing the volume. Do.

  During the ringing tone addition control, the gain setting unit 12 switches the gain of the speaker amplifier 3 to the maximum. The speaker 1 outputs a ringtone at the maximum volume. The gain setting unit 12 further drives the receiver amplifier 4 with the maximum gain in the second mode. The receiver 2 outputs a ring tone simultaneously with the speaker 1 at the maximum volume (S8). By such control, a ringtone having an additional volume with respect to a normal ringtone is output based on the difference between the preset gain and the maximum gain of the speaker amplifier 3 and the gain of the receiver amplifier 4.

  While the user does not off-hook the mobile phone 10 (S9 No), the process of step S8 is continued. When the user notices an incoming call and off-hooks the mobile phone 10 (S9 Yes), the output of the normal ringtone and the additional ringtone is stopped. The gain setting unit 12 returns the gain of the speaker amplifier 3 to the set normal gain, and returns the gain of the receiver amplifier 4 to the gain of the first mode. The user makes a call at the volume of the first mode (S10), and goes on-hook when the call ends (S11).

  The above operation makes it easy for the user to notice even when there is an incoming call when the mobile phone is carried in a bag or a thick jacket pocket, etc., and carried around in a place where the surrounding noise is high.

  When reception of the call stops in step S8, the gain setting unit 12 returns the gain of the speaker amplifier 3 from the maximum gain to a preset gain, and returns the receiver amplifier 4 to the first gain. By such a reset operation, when the next call is received, it is possible to output a ring tone at a normal volume set by the user without any particular operation by the user.

  It is also preferable that the ring tone control unit 11 performs the transient control after the call is stopped as follows. Consider a case where the reception of a call is stopped while the ring tone addition control in step S8 is being performed. In this case, when the incoming call control unit 11 receives a telephone call again within a predetermined period stored in advance, step S7 is skipped and the additional incoming call tone is immediately output in step S8. If the next telephone call has been received after a certain period of time has elapsed, a ringing tone addition control is performed after a normal ringing tone is output for a predetermined time, as in steps S7 to S8.

  When the user does not go off-hook, the caller may stop the call and then try again in a short period of time. In such a case, the user is still likely to be in a situation where it is difficult to hear the ringtone as usual. According to the above transient control, in such a case, the ringtone for the recall is output at a high volume from the beginning, so that the user can easily notice the incoming call. Furthermore, since the normal ringtone is restored after a certain amount of time has elapsed, if the user changes to a quiet location, the ringtone will suddenly sound at the maximum volume, preventing the user from being surprised. .

  Next, the operation when making a call using the speakerphone function will be described. In the mobile phone 10 according to the present embodiment, when making a call using a speakerphone, if it is difficult to hear even if the sound volume from the speaker 1 is maximized due to ambient noise, the sound is simultaneously output from the receiver 2 by a user operation. By doing so, it becomes possible to output a larger volume.

  FIG. 4 shows the operation of the mobile phone 10 when the speakerphone function is used. This operation is continued from step S6 in FIG. When the user performs a predetermined input operation on the input device of the mobile phone 10 in a call state (S12), the speakerphone call unit 13 stops the sound output by the receiver 2, and the call sound by the speaker 1 with a preset gain. Is started (S13). The user makes a call using a speakerphone.

  When the user is under noise and it is difficult to hear the sound, the user performs a predetermined input operation for increasing the volume (S14). The noise call control unit 14 switches the volume of the speaker amplifier 3 from a preset volume to a maximum volume. The noisy call control unit 14 further drives the receiver amplifier 4 with the maximum gain of the second mode, and outputs the voice of the call from the receiver 2 (S15).

  As described above, even when talking on a speakerphone in a place where the surrounding noise is high, the user can easily hear the voice.
