1. A mobile communication apparatus capable of operating in a pre-determined mode, the mobile communication apparatus comprising:
a speaker;
a sound receiving unit for providing a first audio signal based on external sounds;
an audio signal processing unit, connected to the speaker and the sound receiving unit, the audio signal processing unit receiving the audio signal from the sound receiving unit and outputting the coded audio signal to the speaker;
a control unit, connected to the audio signal processing unit, the control unit generating a control signal corresponds to the pre-determined mode and controlling the audio signal processing unit to stop outputting the first audio signal to the speaker based on the first control signal.
2. The mobile communication apparatus of claim 1, wherein the audio signal processing unit receives a second audio signal and outputting coded audio signal to the speaker under the pre-determined mode.
3. The mobile communication apparatus of claim 2, wherein the second audio signal is provided by a remote mobile communication device.
4. The mobile communication apparatus of claim 1, further including an interface unit, connected to the control unit, transmitting an interface signal to the control unit, so that the control unit generating the control signal based on the interface signal to stop the audio signal processing unit from outputting the coded audio signal.
5. The mobile communication apparatus of claim 4, wherein the interface unit includes a touch-sensing module connected to the control unit.
6. The mobile communication apparatus of claim 1, further including a noise filter connected between the speaker and the audio signal processing unit, the noise filter receiving the coded audio signal from the audio signal processing unit and transmitting a low-noise signal to the speaker.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
We claim:
1. A mesh type automatic transmission equipped with an input shaft for introducing power of an engine, a plurality of shift gears, a plurality of cogged clutches, an output shaft for outputting driving force, a counter shaft, and a plurality of counter gears, for transmitting power of the engine to said output shaft by rotating said input shaft with the power of the engine, rotating said counter shaft by rotation of said input shaft, and transmitting rotation of said counter shaft to said output shaft via said counter gear with automatic shifting by engaging and disengaging said cogged clutch to one of said shift gears corresponding to speed; wherein
an assist mechanism for transmitting rotational force of said input shaft to said output shaft by transmitting rotation of said counter shaft via said assist gear, in the period of disengagement of a gear to engagement of a new gear during said shifting, is provided to said output shaft.
2. An automatic transmission according to claim 1, wherein said assist mechanism is provided to the rearward side of a car body than the rearmost gear of said output shaft.
3. An automatic transmission according to any of claims 1 or 2, wherein said assist mechanism starts engaging when a switch command of said cogged clutch is output before said cogged clutch currently engaged with said shift gear is completely disengaged, engages corresponding to torque of an engine to transmit rotational force of said input shaft to said output shaft when said cogged clutch is completely disengaged from said engaged shift gear, and disengages when said cogged clutch is engaged with said shift gear to be engaged according to said switch command.
4. An automatic transmission according to any of claims 1, 2 or 3, wherein said assist mechanism is comprised of an assist clutch, which is constituted from a clutch plate fixed to said output shaft and rotated with said output shaft, and from an assist gear provided so as to rotate freely on said output shaft for transmitting rotation of said counter shaft to said clutch plate by pressing against said clutch plate, and a counter assist gear fixed to said counter shaft and meshed with said assist gear of said assist clutch, and the rotation of said counter assist gear is transmitted to said output shaft via said assist gear and said clutch plate, based on an assist command.
