Abstract

A mobile terminal apparatus includes: a microphone; a switch control unit, which switches between a normal mode, in which a voice uttered toward the microphone is transmitted to an intended party, and a mute mode, in which the voice is not transmitted to the intended party; and a proximity sensor, which detects whether a detection object is in proximity to the proximity sensor, wherein, while the mute mode is being executed, if the detection object is detected by the proximity sensor, the switch control unit switches to the normal mode.

Claims

1. A mobile terminal apparatus comprising:

a microphone;

a switch control unit, which switches between a normal mode, in which a voice uttered toward the microphone is transmitted to a intended party, and a mute mode, in which the voice is not transmitted to the intended party; and

a proximity sensor, which detects whether a detection object is in proximity to the proximity sensor,

wherein, immediately after a start of a telephone call, the normal mode is executed until the first detection of the detection object by the proximity sensor, and when the detection object is no longer detected, the switch control unit switches to the mute mode, and

wherein, while the mute mode is being executed, if the detection object is again detected by the proximity sensor, the switch control unit switches back to the normal mode.

2. The mobile terminal apparatus according to claim 1, further comprising:

a condition detecting unit, which detects a condition of the mobile terminal apparatus, wherein the switch control unit switches to the normal mode based on the condition detected by the condition detecting unit.

3. The mobile terminal apparatus according to claim 1, further comprising:

a movement detecting unit, which detects a movement of the mobile terminal apparatus,

wherein, after the movement detecting unit detects the movement of the mobile terminal apparatus, if the detection object is detected by the proximity sensor, the switch control unit switches to the normal mode.

4. The mobile terminal apparatus according to claim 1, further comprising:

a posture detecting unit, which detects a posture of the mobile terminal apparatus, wherein, after the posture detecting unit detects that the mobile terminal apparatus is tilted more than a predetermined angle, if the detection object is detected by the proximity sensor, the switch control unit switches to the normal mode.

5. The mobile terminal apparatus according to claim 1,

wherein the proximity sensor includes a first detector and a second detector disposed at a position different from the first detector, and

wherein, only if both of the first detector and the second detector detect the detection object, the switch control unit switches to the normal mode.

6. The mobile terminal apparatus according to claim 5, further comprising:

a speaker, which output a voice transmitted from the intended party,

wherein the first detector is disposed around the speaker, and the second detector is disposed to be closer to the microphone than the first detector, and

wherein, when both of the first detector and the second detector do not detect the detection objects, the switch control unit switches to the mute mode.

7. The mobile terminal apparatus according to claim 1, further comprising:

an operating unit provided to perform a switch operation to switch to the mute mode, wherein, if the switch operation is performed, the switch control unit switches to the mute mode.

8. The mobile terminal apparatus according to claim 1, wherein, while the normal mode is being executed, if the proximity sensor detects that the detection object is taken away from the proximity sensor for a predetermined time, the switch control unit switches to the mute mode.

9. The mobile terminal apparatus according to claim 8,

wherein, even when the predetermined time is over, if a specific operation is performed before the predetermined time is over, the switch control unit does not switch to the mute mode.
