Abstract
The utility model discloses a multifunctional playing device with the capability of playing digital signals or simulated signals. The utility model comprises a shell body, an audio or video decoding circuit and a signal reading device, wherein the audio or video decoding circuit is arranged in the shell body. The utility model also comprises a digital signal input interface arranged on the shell body, and the digital signal input interface is used for the connection of other mobile storing devices. A digital signal decoding player arranged in the shell body decodes digital signals input from the digital signal input interface and sends the decoded digital signals to the audio or video decoding circuit; then, audio-video signals are played through a sound-producing device or a display screen. A USB interface or other memory card interfaces and the digital signal decoding player are arranged on the multifunctional playing device, thereby, a mobile storing device with a large storage capacity can be directly used on the multifunctional audio or video playing device. A signal source is not required to be driven by a driving mechanism; thereby, signal output is stable and long time play can be carried out without the replacement of a signal source when the multifunctional audio or video playing device is required to be used at an outdoor place.
