Summary of the invention

This novel goal of the invention is exactly that provide for the deficiencies in the prior art part a kind of is easy to carry, played in stereo, multi-functional switching, be convenient to change the novel portable DVD player of battery.

To achieve these goals, this novel technology contents is: a kind of novel portable DVD player, include: the fore shell with button, display screen, keypad, mainboard, be arranged on the DVD player core on DVD support, drain pan, door, wherein, display screen, keypad, mainboard, the DVD player core being arranged on DVD support is located in the cavity volume of described fore shell and the formation of described drain pan, fore shell, display screen, keypad and mainboard cooperation are positioned at the top of described cavity volume after installing, on DVD support, DVD player core, after installing after drain pan coordinates, be positioned at the bottom of described cavity volume, it is corresponding with DVD player core that door is located at the bottom of drain pan,

In described cavity, be also provided with loudspeaker, passive radiator and audio amplifier gland bonnet, loudspeaker are electrically connected with the voicefrequency circuit on circuit board, the setting corresponding to loudspeaker of passive radiator, audio amplifier gland bonnet is encapsulated in loudspeaker and passive radiator on the inside surface of drain pan, has several phonate holes on drain pan.

In described drain pan, be provided with the power supply search switch card extender being electrically connected with circuit board, this power supply search switch card extender is connected with external antenna on drain pan.

The outside of described drain pan is provided with battery cavities, and battery and battery cover are arranged in battery cavities removably from outside.

On described drain pan, be also provided with handle, handle is concave structure rotating shaft and connects on drain pan.

On described drain pan, be also provided with door self-lock switch.

Adopt after said structure, on this novel inside surface that by audio amplifier gland bonnet, loudspeaker and passive radiator is encapsulated in to drain pan, form the effect of stereo speaker, make this novel acoustics that can send surround sound, better than the acoustics of traditional monaural DVD player; On the other hand, movement is fixed on fore shell, and stability is strong, convenient for maintaining and dismounting; Further: this is novel also can switch the functional module on mainboard by power supply search switch card extender and antenna, can switch DVD playing function to radio function of search, make novel have multi-functional; This is novel also makes the novel battery of being convenient to change by external battery structure, and guarantee equipment is normally worked; Finally, this is novel by the handle of female rotor axis shape, can be used as support and uses, and novel basis inclination is supported and is convenient to watch.

Brief description of the drawings

Fig. 1 is the utility model stereo decomposing structural representation.

Embodiment
