Abstract
The utility model relates to an electronic-organ with a built-in MP3 player. Different from the prior art, an MP3 decoder connected with a CPU is arranged, an audio output port of the MP3 decoder is connected with an input port of an audio amplifier, and the MP3 decoder decodes memory data amplified by the audio amplifier and is played by a loudspeaker; at the same time, music information is sent to a liquid crystal screen for displaying through a displaying output port of the CPU; an MP3 music choosing and playing operational-key connected with the CPU via a matrix control circuit is also arranged; the MP3 music choosing and playing operational-key sends a command via the matrix control circuit; the command is processed through the CPU and then sent to the MP3 decoder, the memory data is read out; and functional operations are performed on the music. The utility model has the advantages as follows: the electronic-organ can not only play like a traditional electronic-organ, but also play MP3 music at the same time, or the MP3 music can be played singly.
Description
Technical field
The utility model relates to a kind of mellotron of built-in MP3 player.
Background technology
Traditional mellotron has key and panel operating key, central processing unit, LCDs, note amplifier and loudspeaker, its function only can realize similarly playing with piano, maturation along with circuit integrated technology and MP3 electronic technology, traditional mellotron is necessary to increase more amusement functions, to satisfy mellotron fan's needs.
Summary of the invention
The purpose of this utility model is at above-mentioned needs, provides a kind of and not only can equally with the conditional electronic qin play, but also can play the MP3 song simultaneously or play the mellotron of the built-in MP3 player of MP3 song separately.
The purpose of this utility model is achieved in that the key and the panel operating key that comprise central processing unit, be connected with central processing unit by matrix control circuit, be connected in central processing unit show output port LCDs, be connected in the central processing unit audio output port note amplifier, connect the loudspeaker of note amplifier; The MP3 decoding device that is connected with described central processing unit is set, the audio output port of MP3 decoding device connects the input port of note amplifier, this MP3 decoding device is used for the memory data decoding of inserting from memory receptacle, and institute's decoded data is by the note amplifier amplification and by loudspeaker plays; Simultaneously, the song information that reads of MP3 decoding device is delivered to LCDs by the demonstration output port of central processing unit and is shown; The MP3 song that is connected with described central processing unit by matrix control circuit also is set to be selected and the play operation key, this MP3 song is selected and the play operation key sends instruction to the MP3 decoding device by matrix control circuit transmission instruction after central processing unit is handled, by MP3 decoding device reading memory data, to the broadcast of song, stop, selecting song, volume control, play mode to select to carry out feature operation.
The utility model, described matrix control circuit can be integrated in the central processing unit.
The utility model, described central processing unit and MP3 decoding device can be located in the same integrated processor.
The utility model, described storer can be USB flash disk or card type memory, certainly, do not limit to above-mentioned listed these outside plug in type memeories.
The utility model, mellotron and MP3 playing function organically combine, and make mellotron further strengthened, realize the dynamic multifunctional performance; Both had and equally with the conditional electronic qin to play, can play the MP3 song simultaneously again, or play the advantage of MP3 song separately.
Following embodiment is further described the utility model in conjunction with the accompanying drawings.
Description of drawings
Fig. 1 is the block scheme of an embodiment of the present utility model.
Embodiment
With reference to Fig. 1, present embodiment is a kind of block scheme of mellotron of built-in MP3 player, key and the panel operating key that comprises central processing unit, is connected with central processing unit by matrix control circuit, be connected in central processing unit show output port LCDs, be connected in the central processing unit audio output port note amplifier, connect the loudspeaker of note amplifier; Be to be provided with the MP3 decoding device that is connected with described central processing unit with the prior art difference, the audio output port of MP3 decoding device connects the input port of note amplifier, this MP3 decoding device is used for the memory data decoding of inserting from memory receptacle, and institute's decoded data is by the note amplifier amplification and by loudspeaker plays; Simultaneously, the song information that reads of MP3 decoding device is delivered to LCDs by the demonstration output port of central processing unit and is shown; The MP3 song that is connected with described central processing unit by matrix control circuit also is set to be selected and the play operation key, this MP3 song is selected and the play operation key sends instruction to the MP3 decoding device by matrix control circuit transmission instruction after central processing unit is handled, by MP3 decoding device reading memory data, to the broadcast of song, stop, selecting song, volume control, play mode to select to carry out feature operation, when carrying out feature operation, the song information that the MP3 decoding device reads is simultaneously delivered to LCDs by the demonstration output port of central processing unit and is shown.
The utility model, the outward appearance of mellotron, key, function, play and wait and traditional the same substantially operation of mellotron, difference be this mellotron built-in the MP3 decoding device, can directly play the MP3 song that is stored in the outside plug in type memeory by USB interface or other outside plug type memory interfaces at mellotron, USB flash disk for example, song in the card type memory, and can on mellotron panel feature keyboard, operate the MP3 playing function, the selection of MP3 song, show the feature operation of MP3 in LCDs, broadcast information such as song serial number name and mellotron are for information about, simultaneously, in playing, also can play MP3, function to mellotron is operated.
During the utility model use, the MP3 decoding device is decoded after reading the interior information of external memory storage, output audio signal, and the while arrives the LCDs demonstration to the message transport that will show after the song information that will show is sent to the central processing unit processing; The feature operation of MP3 decoding device sends instructions to central processing unit by matrix control circuit, handles the back by central processing unit instruction is sent to the MP3 decoding device, realizes the operation controls such as function, song selection to the MP3 decoding device; This central processing unit refers generally to mellotron master IC, audio frequency output arithmetical unit, and this central processing unit also is a control chip of being responsible for control electronic organ key, all functions; Handle to be meant the data that central processing unit is responsible for accepting outside input instruction and is sent instruction directs MP3 decoding device reading external memory through central processing unit, to the broadcast of song, stop, selecting feature operation such as song, volume control, play mode selection and the message transport that the MP3 decoding device is sent here is arrived LCDs export demonstration.
