Description

  The present invention relates to a mobile terminal device and an incoming call notification output control method thereof, and more particularly to a control method of incoming volume or incoming vibration of a mobile phone.

  An incoming call notification output in a mobile terminal device, for example, a mobile phone (for example, an incoming volume or a vibration amount of a vibrator that notifies an incoming call by vibration) can be arbitrarily set by a user. However, it is rare that the incoming call notification output is frequently changed according to the surrounding environment.

  On the other hand, a mobile phone is often used by a user moving due to its character. Therefore, even if the incoming call notification output is set to a constant value, the surrounding environment changes as the user moves, so that the set value is not always optimal. That is, when the user moves to a place where the ambient environmental sound such as noise is relatively loud, the incoming notification information may be canceled by the ambient environmental sound and the incoming notification information may not be recognized. In addition, when an incoming call is notified by vibration of the vibrator, the purpose cannot be achieved if the mobile phone is in a place where it does not touch the skin. Therefore, in this case, only the vibration sound of the vibrator can be relied on. Same as ringtone.

  On the other hand, Patent Document 1 discloses an example of an invention for preventing incoming notification information from being canceled due to such noise. If the noise level is higher than the reference value, the ringtone quality of the existing ringtone is set to high and the volume level is set to high. If the noise level is lower than the reference value, the existing ringtone is received. The sound quality is set to low and the volume level is set to low.

  Another example of this type of invention is disclosed in Patent Document 2. This increases the ringtone volume or vibrator vibration when the ambient volume is greater than the threshold, and keeps the ringtone volume or vibrator vibration when the ambient volume is less than the threshold. That's it.

  In the invention described in Patent Document 1, the volume level of the ringtone is set to a high level if the noise level is higher than the reference value, and the volume level of the ringtone is set to a low level if the noise level is lower than the reference value. This is common with the present invention in that it is set. However, in the present invention, since the volume level to be changed is limited to a large or small binary value, it cannot be set to any other volume. For example, the volume level is set to a high level according to the noise level, but the ringtone cannot be heard sufficiently at that volume level.

  The invention described in Patent Document 2 is common to the present invention in that the volume of the ringtone or the vibration amount of the vibrator is increased when the surrounding volume is larger than the threshold value. However, since the volume level or vibration level to be changed is limited to a large value in the present invention, there is a drawback that it cannot be set to any other volume level or vibration level.

  Next, the small table 71, the standard table 72, and the large table 73 stored in the memory 7 will be described. FIG. 3 is a configuration diagram of an example of a volume setting table stored in the memory 7. The figure shows a small table 71, a standard table 72, and a large table 73 in order from the left. In this table, a list of amplification factors to be set in the amplifier circuit 5 is displayed.

  First, the standard table 72 will be described. The standard table 72 is for the case where the ambient sound described later is within the ambient environment reference range. The standard table 72 includes a volume setting position (shown as “Vol” in the figure) and an amplification factor (same figure). And “OH”) are set correspondingly.

On the other hand, the amplification factor is set so as to increase by 2 OH with respect to the volume setting position of the corresponding standard table 72.

  Next, the operation of the first embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the first embodiment. The following operation is executed by the CPU 3 controlling the memory 7, the AD conversion circuit 2, the amplification circuit 5 and the melody circuit 4. First, ambient sound is collected by the microphone 1 when an incoming call is received, and the collected sound signal is converted from an analog signal to a digital signal by the AD conversion circuit 2 (step S1). Next, the audio signal converted into the digital signal is averaged by the CPU 3 (step S2).

  Next, the CPU 3 compares the averaged audio signal with the ambient environmental sound reference range (hereinafter, referred to as ambient ambient reference range) stored in advance in the memory 7 (step S3). If the ambient sound is within the ambient reference range (“NO” in step S4), the CPU 3 refers to the standard table 72 stored in the memory 7 and sets the amplification factor of the amplifier circuit 5 to the standard. (Step S8). The audio signal amplified by the amplifier circuit 5 is output to the speaker 6, and a melody is output from the speaker 6 (step S9).

  On the other hand, if the ambient environment sound is outside the ambient environment reference range in step S4 ("YES" in step S4), the CPU 3 checks whether the ambient environment sound is larger than the ambient environment reference range (step S5). . If the ambient environment sound is larger than the ambient environment reference range (“YES” in step S5), the CPU 3 refers to the large table 73 stored in the memory 7 and increases the amplification factor of the amplifier circuit 5. (Step S6). The audio signal amplified by the amplifier circuit 5 is output to the speaker 6, and a melody is output from the speaker 6 (step S9).

  On the other hand, when the ambient environmental sound is smaller than the ambient environment reference range in step S5 (in the case of “NO” in step S5), the CPU 3 refers to the small table 71 stored in the memory 7 and The amplification factor is set to a small amplification factor (step S7). The audio signal amplified by the amplifier circuit 5 is output to the speaker 6, and a melody is output from the speaker 6 (step S9). This is the end of the process.

  The CPU 3 refers to the standard table 72 stored in the memory 7 and sets the amplification factor of the amplification circuit 5 to the standard amplification factor (step S8), or refers to the large table 73 and the amplification circuit 5 Is set to a large amplification factor (step S6), or the amplification factor of the amplifier circuit 5 is set to a small amplification factor with reference to the small table 71 (step S7). It is not limited to one.

  That is, as an example, when the standard gain is set (step S8), it is possible to select an arbitrary gain from among the gains shown in the standard table 72 of FIG. On the other hand, when setting a large amplification factor (step S6), the amplification factor corresponding to the amplification factor set in the standard table 72 among the amplification factors shown in the large table 73 of FIG. It is possible to select the amplification factor. When setting a small amplification factor (step S7), the amplification factor corresponding to the amplification factor set in the standard table 72 from among the amplification factors shown in the small table 71 of FIG. It is possible to select the amplification factor.

  In this embodiment, the amplification factor is changed every 2 OH. However, the present invention is not limited to this, and the rate of change of the amplification factor can be arbitrarily set, and the change at each step. The amount is not constant and can be any value.

  As described above, according to the first embodiment of the present invention, it is possible to output a sound volume suitable for the ambient environment from the speaker by changing the amplification factor of the amplifier circuit 5 by the ambient environment sound. This improves the recognition rate of ringtones under noisy conditions (for example, subway homes) and prevents ringing of ringtones at high volumes in quiet environments (for example, indoors at home). It becomes possible. Furthermore, since it has a configuration in which a desired amplification factor is selected from each of the standard, large, and small tables and set in the amplification circuit 5, it is possible to set the incoming call notification output to a desired level according to the ambient environmental sound. .

  FIG. 5 is a block diagram of a second embodiment of the portable terminal device according to the present invention. In the figure, the same components as those in FIGS. 1 and 2 are denoted by the same reference numerals, and the description thereof is omitted. The mobile terminal device in the second embodiment is a mobile phone as an example. Referring to FIG. 5, the difference from the first embodiment (see FIG. 2) is that a vibrator 8 is added to the incoming call notification unit 12, and the other configuration is the same as that of the first embodiment. Therefore, the description of the same components as those in the first embodiment is omitted.

  The vibrator 8 is provided to vibrate the casing of the mobile phone, and notifies the user of an incoming call by vibration. The vibrator 8 is connected to the CPU 3 and is configured to change the rotational speed (that is, the vibration amount) in accordance with an instruction from the CPU 3. Note that the vibration amount of the vibrator 8 is proportional to the rotational speed.

  Further, the memory 7 stores a vibration setting table in which the relationship between the vibration setting position and the vibration amount is set to a small, standard, and large table according to the ambient environmental sound. Since the volume setting position of the volume setting table in the example is replaced with the vibration setting position and the amplification factor in the volume setting table of the first embodiment is replaced with the vibration amount, the illustration is omitted.

  Next, the operation of the second embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the operation of the second embodiment. The following operation is executed by the CPU 3 controlling the memory 7, AD converter circuit 2, vibrator 8, amplifier circuit 5 and melody circuit 4. First, ambient sound is collected by the microphone 1 when an incoming call is received, and the collected sound signal is converted from an analog signal to a digital signal by the AD conversion circuit 2 (step S1). Next, the audio signal converted into the digital signal is averaged by the CPU 3 (step S2).

  Next, the CPU 3 compares the averaged audio signal with the ambient environmental sound reference range (hereinafter, referred to as ambient ambient reference range) stored in advance in the memory 7 (step S3). If the ambient sound is within the ambient reference range (“NO” in step S4), the CPU 3 refers to the standard table 72 stored in the memory 7 and sets the amplification factor of the amplifier circuit 5 to the standard. The vibration amount of the vibrator 8 is set to a standard vibration amount with reference to a vibration standard table (a table corresponding to the standard table 72) (not shown) (step S8). The audio signal amplified by the amplifier circuit 5 is output to the speaker 6, a melody is output from the speaker 6, and the vibrator 8 rotates with a standard vibration amount (step S9).

  On the other hand, if the ambient environment sound is outside the ambient environment reference range in step S4 ("YES" in step S4), the CPU 3 checks whether the ambient environment sound is larger than the ambient environment reference range (step S5). . If the ambient environment sound is larger than the ambient environment reference range (“YES” in step S5), the CPU 3 refers to the large table 73 stored in the memory 7 and increases the amplification factor of the amplifier circuit 5. The vibration amount of the vibrator 8 is set to a large vibration amount with reference to a large vibration table (table corresponding to the large table 73) (not shown) (step S6). The audio signal amplified by the amplifier circuit 5 is output to the speaker 6, a melody is output from the speaker 6, and the vibrator 8 rotates with a large vibration amount (step S9).

  On the other hand, when the ambient environmental sound is smaller than the ambient environment reference range in step S5 (in the case of “NO” in step S5), the CPU 3 refers to the small table 71 stored in the memory 7 and The amplification factor is set to a small amplification factor, and the vibration amount of the vibrator 8 is set to a small vibration amount with reference to a small vibration table (table corresponding to the small table 71) (not shown) (step S7). The audio signal amplified by the amplifier circuit 5 is output to the speaker 6, the melody is output from the speaker 6, and the vibrator 8 rotates with a small amount of vibration (step S9).

  As described above, according to the second embodiment of the present invention, the sound volume suitable for the surrounding environment can be output from the speaker by changing the amplification factor of the amplification circuit 5 by the ambient environment sound, and the vibrator 8 can be output. The amount of vibration can be set to a vibration amount suitable for the ambient environmental sound. As a result, the recognition rate of the ringtone and vibration of the vibrator 8 under noise (for example, a subway home) is improved, and the ringtone of a loud sound is generated in a quiet environment (for example, at home). It becomes possible to prevent the vibration sound of the vibrator 8. Further, since the desired amplification factor and vibration amount are set from the standard, large, and small tables, the incoming call notification output can be set to a desired level according to the ambient environmental sound.

  The third embodiment relates to a program for an incoming call notification output control method for a mobile terminal device. 2 and 5, the portable terminal device according to the present invention includes a program storage unit 9. The program storage unit 9 stores a program for the incoming call notification output control method shown in the flowcharts of FIGS. 4 and 6. The CPU 3 reads the program from the program storage unit 9, and controls the memory 7, the AD conversion circuit 2, the amplification circuit 5, the melody circuit 4 and the vibrator 8 according to the program. Since the control contents have already been described, the description thereof is omitted here.
