Mobile apparatus capable of automatic detection and communication of voice and digital data
First Claim
1. A mobile apparatus capable of automatic detection of both voice and digital data, and communication according to the data detected, comprising:
- a communication means for processing digital data;
a voice module for processing voice data;
a connector comprising a first terminal for receiving a first signal and a second terminal for transmitting a second signal;
a processor coupled to the first terminal for generating a selection signal according to a voltage value of the first signal; and
a selection unit, responsive to the selection signal, for selectively establishing one of a first path and a second path, the first path coupling the first and the second terminals to the communication means, and the second path coupling the first and the second terminals to the voice module.

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.
