Description

  The present invention relates to a mobile phone and a control method thereof.

  Many mobile phones have a vibrator function that vibrates the mobile phone itself instead of a ringing tone such as a bell or ringing melody in order to notify the user that there has been an incoming call or an e-mail. Unlike the bell and ringing melody, the vibrator function is convenient when there is an incoming call in a quiet place because no sound is generated even when the incoming call is received or the sound is relatively small. However, when the mobile phone is placed on a desk or the like, a vibration sound larger than the ringtone may be generated due to the vibration of the mobile phone.

For this reason, there is one that attempts to reduce the vibration sound of the vibrator device by changing the operating voltage of the vibrator device by the sound pressure received by the microphone (Patent Document 1). However, since the vibration of the mobile phone does not stop, it may be louder than the ringtone as before.

Further, the power supply circuit 24 is controlled by the power supply control circuit 25, and power is supplied to each circuit constituting the mobile phone 1.

  The mobile phone 1 has a vibrator function. For the vibrator function, the cellular phone 1 includes a vibrator device 26. The vibrator device 26 is controlled by a vibrator control circuit 27. The mobile phone 1 is provided with a ring tone speaker 28 to inform the user that an incoming call has been received. The ring tone speaker 28 is controlled by a ring tone control circuit 29.

  The voice given to the microphone 12 is converted into a voice signal and input to the modulation / demodulation circuit 34 in the voice control circuit 33 via the transmission / reception circuit 37. The audio signal input by the modem circuit 34 is modulated and applied to the radio control circuit 32. A modulated audio signal is given from the radio control circuit 32 to the antenna 3, and the audio signal is transmitted to the telephone of the other party.

  When a call signal from the telephone of the other party is input to the radio control circuit 32 via the antenna 3, the ring tone control circuit 29 or the vibrator control circuit 27 controls the ring tone speaker 28 or the vibrator device 26 to generate a ring tone or The mobile phone 1 vibrates (the generation of a ringing tone, the vibration of the mobile phone 1 and the like changes according to settings as described later). When the user knows that an incoming call has been received, the user presses the off-hook button in the operation buttons 11 to enable a call. The audio signal transmitted from the other party is input to the radio control circuit 32 via the antenna 3. The audio signal is given to the modulation / demodulation circuit 34 in the audio control circuit 33 and demodulated. The demodulated audio signal is applied to the speaker 4 via the transmission / reception circuit 37, so that the voice of the other party is output from the speaker 4.

  As described above, the mobile phone 1 includes the display device 5 having the display screen 5 (the display device also uses the same code as the display screen) and the liquid crystal display device 6 (the liquid crystal display device uses the same code as the liquid crystal display screen). Is provided. The liquid crystal display screen 6 of the liquid crystal display device 6 is illuminated by the backlight device 30. The mobile phone 1 also includes an external interface 31 for connecting to an external device.

  In the mobile phone 1 according to this embodiment, when there is an incoming call, the incoming call is received by at least one of the vibration of the mobile phone 1 by the vibrator device 26 and the ringtone output from the ringtone speaker 28 according to the setting. The user is informed that there has been. When the vibrator device 26 is set so as to notify that there is an incoming call, when the mobile phone 1 is placed on a desk or the like, the vibration sound generated by the vibration of the mobile phone 1 may be noisy. is there. For this reason, in the mobile phone 1 according to this embodiment, the vibration sound of the mobile phone 1 that vibrates is detected by the vibrator device 26. If the detected vibration sound is above a predetermined level, the vibration by the vibrator device 26 is stopped. Noise generated by the vibration of the mobile phone 1 can be suppressed.

  In order to suppress vibration sound generated when the mobile phone 1 vibrates, the sound control circuit 33 of the mobile phone 1 includes a vibrator sound detection circuit 35 and a filter 36. The filter 36 has a characteristic of passing a signal indicating vibration sound of the mobile phone 1. When the mobile phone 1 vibrates, the generated vibration sound is input to the microphone 12. The vibration sound is converted into a vibration sound signal by the microphone 12, passes through the filter 36 of the sound control circuit 33, and is input to the vibrator sound detection circuit 35. As described above, since the filter 36 has a characteristic of passing a vibration sound signal, a vibration sound signal is input to the vibrator sound detection circuit 35 without inputting a sound signal other than the vibration sound signal. It will be.

  It is determined whether the level of the vibration sound signal input to the vibrator sound detection circuit 35 is equal to or higher than a predetermined threshold level. When the level of the input vibration sound signal is equal to or higher than a predetermined threshold level, a vibrator sound detection signal is output from the vibrator sound detection signal 35 and input to the vibrator control circuit 27. The vibrator device 26 is stopped by the vibrator control circuit 27.

  The microphone 12 for inputting the vibration sound of the cellular phone 1 is for calling as described above, but another microphone for detecting the vibration sound without using the calling microphone is provided in the cellular phone 1. Also good.

  FIG. 4 is a flowchart showing a procedure for setting the manner mode in the mobile phone 1, and FIG. 5 is an example of a manner setting menu image displayed on the display screen 5.

  When the menu button of the cellular phone 1 is pressed, a menu image is displayed on the display screen 5. Icons for performing various settings are displayed in the menu image. When the manner setting is selected by the user (YES in step 41), the manner setting image shown in FIG. 5 is displayed on the display screen 5 (step 42).

  Using the manner setting image, it is possible to set the key confirmation sound, set the incoming vibrator, set the automatic vibrator stop, and set the incoming call volume. The key confirmation sound is set to turn on / off a sound generated when the operation buttons 11 of the mobile phone 1 are pressed. The setting of the incoming call vibrator is to turn on / off the function of vibrating the mobile phone 1 by the vibrator device 26 when the incoming call is received as described above. As described above, when the vibrator is automatically stopped, the vibration of the mobile phone 1 by the vibrator device 26 is stopped when the level of vibration sound generated by the vibration of the mobile phone 1 by the vibrator device 26 is equal to or higher than a predetermined level. It defines the operation of the time. If the ring tone setting described later is turned off, the user does not know that the incoming call has been received. For this reason, this is a setting for automatically stopping the vibrator to notify the user that there is an incoming call when the vibration of the mobile phone 1 is stopped. There are “LED”, “strobe”, “sound output”, and “non-notification” as the settings when the vibrator is automatically stopped. “LED” is set so as to notify the user that there is an incoming call by causing the light emitting diode 9 to emit light (turn on or blink) when vibration by the vibrator device 26 is stopped. Similarly, the “strobe” causes the strobe light emitting device 8 to emit light (turns on or blinks), and the “sound output” notifies the user that an incoming call has been received by outputting a ring tone from the ring tone speaker 28. Is. “Non-notification” does not particularly notify the user when the vibrator device 26 is stopped even when there is an incoming call.

  In the manner setting image, these settable items and the setting contents (ON, OFF, etc.) are displayed. A cursor C is displayed so as to surround any one item and setting contents among the items displayed on the manner setting image and the setting contents. The cursor C moves upward or downward in response to pressing of an up arrow or down arrow on the up / down / left / right buttons provided on the mobile phone 1. The setting contents of the setting items surrounded by the cursor C change according to the pressing of the left arrow or right arrow of the up / down / left / right buttons.

  Returning to FIG. 4, when the setting of the incoming vibrator is turned on (YES in step 43), the fact is stored in the cellular phone 1 (step 44). If the incoming vibrator setting is off (NO in step 43), the process of step 44 is skipped.

  When the process for automatically stopping the vibrator is set (NO in step 45), the set process content is stored in the mobile phone 1 (step 46).

  Thereafter, other items are set in the same manner.

  FIG. 6 is a flowchart showing a processing procedure when the mobile phone 1 is in the standby mode.

  When there is an incoming call (YES in step 51), it is confirmed whether the incoming vibrator setting is turned on (step 52). If the incoming vibrator setting is turned on (YES in step 52), the drive of the vibrator device 26 is started due to the incoming call (step 53). Since the mobile phone 1 vibrates, the user knows that there was an incoming call (either a call or an e-mail).

  As described above, the vibration sound generated when the mobile phone 1 vibrates is input to the microphone 12 (step 54), and the vibration sound signal is input to the vibrator sound detection circuit 35. If the level of the vibration sound signal input to the vibrator sound detection circuit 35 is equal to or higher than a predetermined level (YES in step 55), it is felt loud due to the vibration sound, so the vibrator device 26 is driven to stop the vibration of the mobile phone 1. Is stopped (step 56).

  When the vibrator device 26 is stopped (when the vibrator is automatically stopped), it is confirmed whether or not the setting is “non-notification” (step 57). If not set to “non-notification” (NO in step 57), According to the set contents, the incoming call notification is performed as described above (step 58). If “LED” is set, the light emitting diode 9 emits light, if “strobe” is set, the strobe light emitting device 8 emits light, and if “sound output” is set, the ring tone speaker 28 emits sound. Is output. When “non-notification” is set, the notification process is skipped.

  If the incoming vibrator is set to OFF (NO in step 52), the processing of steps 53 to 58 is skipped. If the vibration sound of the mobile phone 1 generated by driving the vibrator device 26 is less than a predetermined level (NO in step 55), the processing of steps 56 to 58 is skipped.

  When the off-hook button is pressed by the user, a receiving operation is performed (YES in step 59), and a call is started. When the menu button 13 is pressed and browsing of electronic mail is selected, communication processing such as an electronic mail browsing operation is performed.

The external appearance of a mobile phone is shown. The mobile phone is shown in a bent state. It is a block diagram which shows the electric constitution of a mobile telephone. It is a flowchart which shows a manner mode setting process sequence. It is an example of a manner setting image. It is an example of a processing procedure in standby mode.
