Abstract

<P>PROBLEM TO BE SOLVED: To provide a mobile phone for preventing a bone conduction speaker 106, which is used when a flip 102 is closed, from being out of use by a function of terminating a speech when the flip 102 is closed. <P>SOLUTION: A user uses a key entry reception section 208 to select a use mode wherein the bone conduction speaker 106 is used or an out of use mode wherein the bone conduction speaker 106 is not used. A control section 204 receives the notice of the selection from the key entry reception section 208 to set the use mode or the out of use mode. When the use mode is set, even when an opening/closing detection section 206 detects the closing state of the flip 102, the control section sets a speech termination OFF wherein no speech is terminated. When the out of use mode is set, the control section sets a speech termination ON wherein a speech is terminated when the closed flip is detected. When receiving the closing state from the opening/closing detection section 206 during a speech, the control section 204 instructs a voice control circuit 205 to switch an output to the bone conduction speaker 106 when the use mode is selected. <P>COPYRIGHT: (C)2005,JPO&NCIPI

The antenna 104 receives a radio wave transmitted from a base station (not shown) and notifies the radio circuit 202. Further, the signal notified from the radio circuit 202 is transmitted to the base station.
The radio circuit 202 down-converts the radio wave notified from the antenna 104 and notifies the signal processing circuit 203 of it. The signal notified from the signal processing circuit 203 is up-converted and notified to the antenna 104.

The signal processing circuit 203 performs signal processing necessary for communication on the signal notified from the wireless circuit 202, notifies only the sound signal to the sound control circuit 205, and notifies the control unit 204 of the control signal. In addition, the digital signal notified from the voice control circuit 205 is shaped into a timing and format suitable for communication, and notified to the wireless circuit 202.
The control unit 204 is configured by a CPU, controls each unit of the folding mobile phone, and the CPU operates according to a program recorded in the memory 207.

The control unit 204 receives a notification from the key input receiving unit 208 that the user selects a use mode in which the bone conduction speaker is used or an unusable mode in which the user is not used, and sets the use mode or the unusable mode.
The control unit 204 also controls the start or end of a call state by detecting opening / closing of the flip 102. When the use mode is notified from the key input accepting unit 208, the call end off is set so as not to end the call state even if the closed state is notified from the open / close detection unit 206. When the unusable mode is notified, when the closed state is notified, the call end ON for ending the call state is set.

  When the closed state is notified from the open / close detection unit 206, the control unit 204 receives a control signal notification from the signal processing circuit 203 or a voice signal notification from the voice control circuit 205, that is, is in a call state. When the use mode is set, the voice control circuit 205 is instructed to switch the voice output from the receiver speaker 210 to the bone conduction speaker 106. When the unusable mode is set, the call state is terminated.

Whether or not the telephone is in a call state may be determined by an operation signal of a call start key or a call end key notified from the key input reception unit 208.
The audio control circuit 205 performs digital / analog conversion on the audio signal notified from the signal processing circuit 203 and outputs it to the receiver speaker 210 or the bone conduction speaker 106 instructed from the control unit 204. In addition, the audio signal notified from the microphone 212 is converted from analog to digital and notified to the signal processing circuit 203 and the control unit 204.

The opening / closing detection unit 206 detects the opening / closing of the flip 102 and notifies the control unit 204 of the opening / closing.
The memory 207 is formed from a ROM or the like, and stores a control program for the folding mobile phone.
The key input accepting unit 208 has numeric keys and other operation keys, receives input of the other party number at the time of calling, operations such as a call start key, a call end key, and the like from the user, and receives the operation signal from the control unit 204. Notify

The receiver speaker 210 is a normal speaker and is used in the open state of the flip 102. An audio signal notified from the audio control circuit 205 is output as audio.
The bone conduction speaker 106 is a speaker that transmits sound from other than the eardrum by bone conduction sound transmitted from the bone. The bone conduction speaker 106 outputs an audio signal notified from the audio control circuit 205 as vibration. The bone conduction speaker 106 can be put around the ear and the other party's voice can be heard. Accordingly, the voice of the other party can be heard even in a noisy place, and the voice can be heard even by a hearing-impaired person due to a tympanic membrane disorder. The bone conduction speaker 106 can be used with the flip 102 closed when the use mode for using the bone conduction speaker is set.

The microphone 212 collects the user's voice and notifies the voice control circuit 205 of the voice signal.
Next, the operation of the present embodiment will be described with reference to the flowcharts of FIGS.
FIG. 4 is a flowchart for explaining the setting operation in the use mode or the unusable mode for determining whether or not to use the bone conduction speaker.
First, the user selects a mode setting from the menu screen of the main display unit, and selects a use mode or an unusable mode. This selection is notified from the key input receiving unit 208 to the control unit 204 (S302).

When the usage mode is selected, the control unit 204 sets the usage mode and turns off the call termination control associated with the detection of the closing of the flip 102 (S304). As a result, even if the flip 102 is detected during a call, it is prohibited to end the call, and the call can be continued with the bone conduction speaker.
When the unusable mode is selected, the control unit 204 turns on the call termination control associated with the detection of closing of the flip 102 (S306), and ends the process. Thereby, when the bone conduction speaker 106 is not used, the flip 102 is closed, and the call is ended.

FIG. 5 is a flowchart for explaining the switching operation of the bone conduction speaker during a call.
First, the control unit 204 waits for a user to talk over the receiver speaker 210 and the microphone 212 (S402), and waits for a notification of detection of the closed state from the open / close detection unit 206 (S404). If there is a notification of the closed state, it is determined whether or not the use mode is set for the bone conduction speaker (S406).

If the use mode is set, the voice control circuit 205 is instructed to switch from the output to the receiver speaker 210 to the output to the bone conduction speaker 106. The user continues the call with the bone conduction speaker 106 (S408) and ends the process.
In S406, when the unusable mode is set, the voice control circuit 205, the signal processing circuit 203, etc. are instructed to disconnect the call, and the call is ended (S410).

As described above, when the use mode is set for the bone conduction speaker 106, the bone conduction speaker 106 is processed by subordinate the function of turning the call on to end the call when the flip 102 is folded and closed. Can be used smoothly.
In the above embodiment, although the user has linked the setting of the use mode using the bone conduction speaker 106 or the setting of the unusable mode in which the user does not use the call end function by detecting the closed state of the flip 102, the user It may be changed by manual operation.

FIG. 6A shows a first selection screen for changing the mode when the use mode is set for the bone conduction speaker. The first selection screen 501 is displayed on the main display unit by selecting mode switching from a menu screen, for example.
The user can select “1” 502 or “2” 503 to change the mode as it is.

The key input reception unit 208 notifies the control unit 204 when “1” 502 is selected. The control unit 204 does not do anything because the use mode has already been set for the bone conduction speaker and the call end is set to not end the call even if the close detection is detected.
When the control unit 204 receives the notification “2” 503 from the key input reception unit 208, the control unit 204 sets the call end on, which ends the call when it is detected as closed, and sets an unusable mode for the bone conduction speaker.

The user can change the use mode once set to the unusable mode.
FIG. 6B shows a second selection screen for changing the mode when the unusable mode is set for the bone conduction speaker. Similarly, the second selection screen 504 is displayed on the main display unit.
The key input reception unit 208 notifies the control unit 204 when “1” 505 is selected by the user.

The control unit 204 does not do anything because the disabled mode has already been set for the bone conduction speaker, and the call end on is set by the close detection.
When notified of “2” 506, the control unit 204 sets the call end off when the closed state is detected while the disabled mode is set in the bone conduction speaker. According to the selection of “2” 506, even if the flip 102 is closed, the call state is not terminated, but the bone conduction speaker cannot be used.

In the above embodiment, the first housing of the mobile phone has been described as the flip 102. However, when the first housing is a sliding or rotating mobile phone and is slid and rotated, Of course, when the bone conduction speaker can be used, the call termination function can be controlled in conjunction with the slide or rotation.
