Abstract text

The invention includes a mobile communication apparatus and an audio switching method. The mobile communication apparatus according to the invention includes a receiver, a speaker, an optoelectronic sensing component, and a control unit. The optoelectronic sensing component is used to sense an environment state and generate an optical detection signal representing a result of sensing the environmental state. The control unit is coupled to the receiver, the speaker, and the optoelectronic sensing component. And, the control unit receives the optical detection signal and selectively outputs an audio signal via the receiver or the speaker according to the optical detection signal.
