A multimedia video and audio player includes an upper cover, and a main body; the upper cover includes a display screen for showing characters, figures, and images; the main body is pivoted to the upper cover, and it includes a holding recess for holding a portable multimedia player, a forwards and backwards movable fastening mechanism for fixing and electrically connecting the portable multimedia player, speakers, and volume control buttons for adjusting the sound volume; when a portable multimedia player is held in the holding recess and fastened and electrically connected by means of the fastening mechanism, signals can be transmitted from the portable multimedia player to the main body for sound to be played out through the speakers and images displayed on the display screen.

Claims

1. A multimedia video and audio player, comprising

(a) an upper cover;

the upper cover including a display screen for showing characters, figures, pictures, and images;

(b) a main body pivoted to the upper cover at one edge thereof;

the main body including;

a holding recess for holding a portable multimedia player;

a fastening mechanism for fastening a portable multimedia player held in the holding recess;

the fastening mechanism being movable forwards and backwards;

a plurality of speakers; and

a plurality of volume control buttons for controlling volume of output sound;

the fastening mechanism being going to electrically connect a portable multimedia player when the portable multimedia player is held in the holding recess and fastened with the fastening mechanism, thus allowing signals to be transmitted from the portable multimedia player to the main body for sound and images to be presented through the speakers and the display screen.

2. The multimedia video and audio player as claimed in claim 1 further comprising a fitting member, which includes an outer frame fitting the holding recess of the main body, an inner frame having an internal space, and a gap abutting the internal space of the inner frame;

the fitting member being fitted in the holding recess of the main body with a small-sized portable multimedia player, which is smaller than the holding recess, being fitted in the inner frame thereof so that the small-sized portable multimedia player is fixed in position;

the gap being going to face the fastening mechanism when the fitting member is fitted in the holding recess of the main body.

3. The multimedia video and audio player as claimed in claim 1, wherein the main body has a gap, a through hole communicating with the gap on a bottom side thereof, and step-shaped portions around the through hole while the fastening mechanism includes:

a plate-shaped pushing part;

the plate-shaped pushing part having two L-shaped hooks facing in opposite directions on a bottom side thereof, and a connecting element at a front end, which will allow data transmission when inserted into a portable multimedia player; and

a flat limiting part having a -shape;

the flat limiting part being fixed right under the gap of the main body;

the plate-shaped pushing part being fitted in the gap of the main body and pressed against the step-shaped portions in a forwards and backwards movable manner with the L-shaped hooks being passed through the through hole and hooked over inward edges of the flat limiting part.

4. The multimedia video and audio player as claimed in claim 1, wherein the main body includes:

a central control unit;

the central control unit allowing a portable multimedia player to be connected thereto and being used for coding and decoding input/output video and audio data and used as a core of control and processing of other signals;

an AV signal switch unit connected to the central control unit;

the AV signal switch unit having a first end allowing an external device to be connected thereto for input of video and audio signals;
