  • Portable digital music playback device
    Publication number: 20070016315
    Abstract: A portable digital music playback device integrates a digital music walkman connection interface, a power supply unit, a data transmission interface and a multi-channel loudspeaker together. The portable digital music playback device is used to connect a digital music walkman, to play music, to transmit data, and to perform charging actions. Through a multi-channel design, a better sound quality of played music can be achieved. Moreover, because several transmission interfaces are integrated together, more convenient operations can be accomplished for users.
