  • Mobile apparatus capable of automatic detection and communication of voice and digital data
    Patent number: 7139590
    Abstract: A mobile apparatus with automatic detection and communication of voice and digital data. The mobile apparatus has a voice module for processing a voice signal and communication means for serial transmission and reception of a digital data signal. Also, the mobile apparatus includes a connector, a processor and a selection unit. The connector has a first, second and third terminal used to receive and transmit a first, second and third signal respectively. The processor detects the third signal periodically and employs conversion means for converting the first signal into a voltage value to set a selection signal when the third signal is detected at a predetermined state. According to the selection signal, the selection unit establishes a first path between the connector and the communication means or establishes a second path between the connector and the voice module to pass the first and the second signals.
