[0024]
Alert 1 and alert 2 are classified into category A1 as alerts issued only during a call, and alert 3 and alert 4 are classified into category A2 as alerts not issued only during a call (category A).
[0025]
In another classification method (classification B), the alert 1 and the alert 2 are classified as being output from the ear speaker (4) arranged in the earpiece (J) directly or to an adjacent ear. In B1, the alert 3 and the alert 4 are classified into the category B2 as being output to the ear which is not close to the speaker (8) disposed on the back of the earpiece (J).
[0026]
Next, main operations of the present invention will be described. FIG. 4 is a flowchart showing the operation of the control circuit (12). When outputting the alerts 1 to 4 (S1) and not during a call (N in S2), the control circuit (12) assumes that the mobile phone device is at a position away from the ear and alerts at the set volume. Is output (S3). Further, when the placement detecting means (18) detects that the mobile phone device is placed on the placement portion (40) (Y in S4), it is determined that the mobile phone device is located away from the ear. An alert is output at the set volume (S3).
[0027]
As a result, even if the volume is set to “loud”, the user does not give any discomfort to the user because the mobile phone device is away from the ear. Therefore, the sound is output at the volume set by the user.
[0028]
If the alert to be output is an alert that is issued only during a call (those belonging to the category A1) (Y in S5), the alert is output at the set volume (S3).
[0029]
As a result, even if the volume is set to “loud”, the volume is within a range that does not hinder use during a call, so that the user does not feel uncomfortable. Therefore, the sound as set by the user is output.
[0030]
If the alert to be output does not belong to the category A1 in FIG. 3 (N in S5) and the volume set for the alert to be output is neither “medium” nor “high”, If N) in S6, that is, if "silence" or "small" is set, an alert is output at the set volume (S3).
[0031]
Then, an alert during a call (Y in S2), the mobile phone device is not mounted on the receiver (40) (N in S4), and an alert to be output belongs to the category A1. If it is not (N in S5) and the set volume is “medium” or “loud” (Y in S6), the volume is output as “low” regardless of the set volume (S7).
[0032]
As described above, the volume during a call is set to a predetermined level or less, except when it is considered that the user does not feel uncomfortable. As a result, the setting of the user is not unnecessarily ignored.
[0033]
Next, a second embodiment will be described. The block diagram of the second embodiment is the same as FIG. 1 of the first embodiment. FIG. 5 is a flowchart showing the operation of the control circuit (12) of the second embodiment, in which step S5 in the flowchart (FIG. 4) of the first embodiment is changed to step S11. Only operations different from those in the first embodiment will be described.
[0034]
When an alert is output (Y in S1), a call is in progress (Y in S2), and the mobile phone device is not placed on the receiver (40) (N in S4), the control circuit (12) returns Then, it is checked whether or not the speaker for issuing the alert is the speaker (4) arranged in the receiver (J) (class B1 in FIG. 3) (S11). That is, it is determined whether the speaker that emits the alert is placed at a position that emits an alert to the ear directly or close to the ear or a position that emits an alert to an ear that is not close to the speaker.
[0035]
If the speaker that emits the alert is provided in the earpiece (J) (Y in S11), even if the volume is set to “loud”, the volume will not interfere with use during a call. The alert is output at the set volume assuming that the volume is in a range not present (S3). Thus, even if the volume is set to “loud”, the user does not feel uncomfortable and outputs the sound as set by the user.
[0036]
If the speaker that emits the alert is not provided in the receiver (J) (N in S11), the process proceeds to step S6. As in the first embodiment, when the set volume is "medium" or "loud" in step S6, the volume is output as "low" regardless of the set volume (S7). .
[0037]
As described above, in the first embodiment, whether or not the volume is reduced to a predetermined level or less is determined based on whether or not the notification sound is emitted only during a call (classification A). However, as in the second embodiment, Alternatively, the determination may be made based on whether or not the speaker that emits the notification sound is disposed in the receiving section (J) (a position that emits an alert to the ear directly or in proximity to the ear) (class B).
[0038]
Although the speaker (4) of the second embodiment is disposed at a position close to the ear, the present invention is not limited to such a speaker, but is an earphone directly inserted into the ear. Is also good.
[0039]
Next, a third embodiment will be described. The block diagram of the third embodiment is the same as FIG. 1 of the first embodiment. FIG. 6 is a flowchart showing the operation of the control circuit (12) of the third embodiment, in which step S4 of the flowchart (FIG. 4) of the first embodiment is changed to step S21. Only operations different from those in the first embodiment will be described.
[0040]
First, switching to a hands-free call will be described. When the ignition switch is turned on with the cable connected to the mobile phone device and is mounted on the mounting portion (40), the control circuit (12) controls the ignition switch detection means (17) and the mounting detection means. The car kit mode is set by (18). In the car kit mode, the control circuit (12) controls the switching circuit (11) to switch from the normal call using the speaker (4) and the microphone (6) to the external speaker (301) of the car kit (30). Switch to hands-free call using external microphone (302).
[0041]
In FIG. 6, when an alert is output (Y in S1) and a call is in progress (N in S2), the control circuit (12) of the third embodiment determines whether or not it is a hands-free call. A check is made by the ignition switch detection means (17) and the placement detection means (18) (S21).
[0042]
If it is a hands-free call in step S21, the control circuit (12) outputs the alert at the set volume assuming that the alert is issued from a position away from the ear (S3). If it is not a hands-free call in step S21, the process proceeds to step S5, and the same operation as step S5 in the first embodiment is performed.
[0043]
In this way, in a hands-free call, there is no problem that the volume is set to a low level ignoring the user's setting.
[0044]
【The invention's effect】
As described above, according to the present invention, the volume of all notification sounds during a call is not reduced by ignoring the setting, but the notification sound is output at the volume set as long as the setting does not cause any problem. Whether or not there is no problem even if the setting is not changed depends on whether (1) the notification sound emitted is only emitted during a call, and (2) the notification sound output means is connected to the receiver (directly or close to the ear). (3) whether the mobile phone device is placed at a predetermined position, (4) normal call mode or hands-free mode (loud voice). Call mode). As a result, it is possible to prevent a sound that does not cause a problem from being set to a small volume ignoring the user's setting.
