The pop-up interface module 34 further includes a SD card interface 39 for connecting an external SD card. As shown in FIG. 2, when the pop-up interface module 34 is located in a first position, the pop-up interface module 34 does not protrude from the main body 32 so that the memory interface 36 and the SD card interface 39 are contained inside the main body 32. As shown in FIG. 3, when the pop-up interface module 34 is located in a second position, the pop-up interface module 34 protrudes from the main body 32 so that the memory interface 36 and the SD card interface 39 are exploded out of the main body 32 and the user can plug in or pull out the memory device 38 or the external SD card. The main body 32 includes a first surface 40, and the pop-up interface 34 includes a second surface 42 and a third surface 44. The memory interface 36 and the SD card interface 39 are disposed on the second surface 42. When the pop-up interface module 34 is located in the first position shown in FIG. 2, the third surface 44 aligns with the first surface 40 substantially so that the second surface 42 is contained inside the main body 32. When the pop-up interface module 34 is located in the second position shown in FIG. 3, the third surface 44 protrudes from the first surface 40 so that the second surface 42 protrudes from the main body 32 and the user can plug in or pull out the memory device 38 or the external SD card.

In addition, an audio-in interface 46 is further disposed on the second surface 42 of the pop-up interface module 34. When the multimedia playing device 30 is playing a first audio signal, such as a radio signal or a CD audio signal, and the pop-up interface module 34 is located in the second position shown in FIG. 3 and the memory device 38 is connected to the audio-in interface 46, the multimedia playing device 30 stops playing the first audio signal and will play an audio file stored in the memory device 38 automatically. Similarly, when the pop-up interface module 34 is located in the second position shown in FIG. 3 and the memory device 38 is connected to the memory interface 36 or the external SD card is plugged into the SD card interface 39, the multimedia playing device 30 stops playing the first audio signal and will play an audio file stored in the memory device 38 or the external SD card automatically. The memory device 38 can transmit audio signals to the audio-in interface 46 of the multimedia playing device 30 via an audio-out interface of the memory device 38, such as an earphone interface. Then a speaker of the multimedia playing device 30 outputs audio signals transmitted from the memory device 38 directly. When the memory device 38 is connected to the memory interface 36 of the multimedia playing device 30, the multimedia playing device 30 processes multimedia data stored in the memory device 38 and plays the processed multimedia data. A reset button 48 is disposed on the second surface 42 for restoring the multimedia playing device 30 to an initial condition when the multimedia playing device 30 can not work normally.

The memory device 38 can be always connected to the memory interface 36 even when the pop-up interface module 34 is located in the first position and the memory device 36 is contained inside the main body 32.

In contrast to the conventional multimedia playing device, the multimedia playing device of the present invention provides the pop-up interface module so that the memory interface can be accommodated inside the main body when the user does not remove the memory device and the memory interface protrudes from the main body when the user removes the memory device. It can economize the space. Furthermore, the memory device is connected to the memory interface of the pop-up interface module obliquely or horizontally to the main body instead of being inserted into the main body perpendicularly. It can prevent that the memory device pierces a driver when a vehicle with the multimedia playing device brakes suddenly. The pop-up interface module can be designed as a shrinking mechanism so that the pop-up interface module shrinks back to the main body when an external force is applied to the pop-up interface module. The present invention can reduce danger of the driver and increase safety of the automobile multimedia playing device.
