Abstract
A wireless transmitter (300) communicates with a wireless earphone (100) to obtain remote communications. The wireless earphone includes: a wireless network card (30′) complying with the 802.11a/b/g standard, for receiving data packets and unpacking them to release digital audio signals; a control processor (20′) connected with the wireless network card, for dealing with the digital audio signals; and a digital-to-analog converter (50) connected with the control processor, for converting the digital audio signals to analog audio signals. The wireless transmitter has a structure similar to that of the wireless earphone, except that the wireless transmitter has an analog-to-digital converter (10) instead of the digital-to-analog converter.
