Abstract

The invention provides a multimedia system. The multimedia system comprises a portable device and a multimedia expansion device, wherein, the portable device is provided with a host computer and a first display, and the host computer is provided with a first multimedia module and a switching module; and the multimedia expansion device is provided with a slot, a multimedia converting circuit, a plurality of signal output interfaces and a power control circuit, wherein, the slot is coupled with the portable device, the multimedia converting circuit is respectively combined with a second multimedia module and a repeater, the power control circuit provides a power source to the slot, the multimedia converting circuit and the signal output interfaces, and the signal output interfaces are coupled with a second display. In the multimedia system, the switching module can switch a multimedia signal output by the host computer to the first multimedia module or the multimedia converting circuit; the multimedia converting circuit is electrically connected with the second multimedia module or the repeater selectively; and the power control circuit stops power output when the slot is separated from the portable device.

Description

【Technical field】 [0001] The invention relates to a multimedia system, in particular to a multimedia system capable of expanding the functions of portable devices. 【Background technique】 [0002] Portable devices (such as notebook computers) have the advantages of small size and easy portability, and have been widely accepted by consumers. However, in order to achieve the purpose of lightness, the design of internal components of portable devices is mainly built-in, such as a built-in display chip or a built-in audio chip. The advantage of built-in is small size, and the disadvantage is that it is not easy to replace and expand Or upgrade. [0003] Especially some computer players, users of 3D games or 3D graphics often need higher-level hardware performance to execute special software programs. Once the hardware performance of the portable device is not enough, you must use a higher-level portable device. device, or through a multimedia expansion device to execute these s...
