Embodiment

Enumerated the specific embodiments that MP3 is connected with automobile audio below, the present embodiment is equally applicable to being connected of MP4 and automobile audio.

This routine MP3 player 3 is prolate side's bodily form, thereafter end face is provided with socket 31 (see figure 2)s, its two lateral wall be provided with can with bump pearl and bump a pair of recess 33 that connects, MP3 player casing upper and lower covers is formed by aluminium alloy punching press and surface treatment, and the recess on its two side is by the ABS plastic once injection moulding.

On the automobile audio front panel, be provided with slot 2 as common audio tape putting groove, be provided with the band bottom surface in this slot, the Connection Block 4 (Fig. 3) of two side and back wall, wall is provided with plug 41 (see figure 3)s that can be electrically connected with the socket 31 on the MP3 player behind the described Connection Block, be respectively equipped with on the both sides inwall of Connection Block and can bump pearl 42 (Fig. 3) with corresponding recess convex-concave on player two lateral walls cooperates, when with player to the slot interpolation on earth the time, plug socket connection on the wall behind the Connection Block in the socket of player rear end face and the slot, simultaneously the lucky elasticity of pearl of bumping on the Connection Block two side embeds corresponding recess on the player two side, player is locked, two side impact pearls add plugs and sockets can realize Three-point machine tool location to player, strengthened the fastness that player is connected with automobile audio, player is played against shock, the effect of steady-working state.When outwards pulling out the MP3 player, steel ball can skid off from recess, easily extracts player.

Guiding and position-limiting action when the above-mentioned Connection Block 4 that is arranged in slot 2 sockets can play plug MP3 player, providing accurate in locating point and support to a locking device that crashes the pearl structure again, simultaneously also is the connecting line that is connected with the MP3 player of the main frame of automobile audio and the fixed support of socket.

Described to bump pearl be by steel ball and galvanized iron sheet punching press and assemble, with steel ball the bumping in the pearl blind hole of Connection Block sidewall of packing into.

The above-mentioned socket that is provided with on player 31 is the special-purpose gang socket that has the tight function of little ball catch, thereby can make plug 41 be connected more firmly with socket 31.

The above-mentioned plug 41 that is provided with on wall behind socket 31 that is provided with on the player rear end face and the Connection Block can be exchanged setting, equally, what be provided with on recess 33 that is provided with on the player sidewall and the Connection Block sidewall bumps pearl 42 and also can exchange setting, all belongs to equivalent technical solutions.

Leading section at the MP3 player has designed a flash memory expansion card notch 32, after plugging the flash memory expansion card, can make the memory space of player reach 8GB, store digital music and the voice document of thousands of head, no matter whether the MP3 player is inserted on the automobile audio, all can change SD/MMC flash memory expansion card easily, bring great convenience to the user.

Be provided with the hinged upset protective door 21 of coboundary and notch coboundary on the preceding notch of slot 2, when not inserting the MP3 player, the upset protective door falls, and plays dustproof and effect attractive in appearance.

After the MP3 player being inserted the slot of automobile audio panel, being about to signal output part and power end and automobile audio connects, only need to forward the acoustic function button to the MP3 shelves, can make the output of player signal connect the conversion of signals and the power amplification unit of automobile audio, play the digital music of its storage,, do not influence other functions of automobile audio no matter the MP3 player is to insert or pull up, CD/ radio reception AM/FM is still available, only needs that feature button is transformed into corresponding shelves and gets final product.

Simultaneously this example in the MP3 player circuit, designed the lithium battery of anti-floating charge and audio frequency anti-interference/wide temperature operating circuit, effectively to prevent from automobile, to use the electromagnetic interference (EMI) brought and the impact of high/low temperature.

This device can be listened to the music in the slot of plug audio tape with MP3 player insertion automobile audio, the MP3/MP4 player itself is a unit that works alone, it can be used as a digital music and voice document source when inserting automobile audio, makes automobile audio play-over the digital music and the voice document of the forms such as MP3/WMA of magnanimity.Also can be separately after extracting move and use as the MP3 player of a standard: available stereophone be listened digital music and voice document, also can connect computer downloads easily or upgrades digital music and voice document, also can be used as a mobile USB flash disk memory, and be that mobile office is used.
