Abstract

The utility model relates to an electronic organ equipped with a MP3 playing device and an electronic piano equipped with a MP3 playing device. The electronic organ or the electronic piano comprises an operating control panel and keys, a matrix control circuit, a sound source integrated device, an audio frequency amplifier, and a loudspeaker which are successively and electrically connected. The sound source integrated device is electrically connected with a display driving device. Compared with a product, the electronic organ or the electronic piano is independently equipped with a MP3 playing device which comprises a control panel-MP3 operating keys, a MP3 data interface, and a MP3 data processor. The output ends of the MP3 operating keys and the output end of the MP3 data interface are electrically connected with the input end of the MP3 data processor while the output end of the MP3 data processor is electrically connected with the input end of the audio frequency amplifier. The electronic organ equipped with a MP3 playing device and the electronic piano equipped with a MP3 playing device can be played as a conventional electronic organ or a conventional electronic piano is played, and external MP3 music can be played by the electronic organ or the electronic piano or is used as accompanied music.

Description

Mellotron and pianotron with the MP3 playing device
Technical field
The utility model relates to a kind of mellotron with the MP3 playing device and pianotron.
Background technology
Traditional mellotron and pianotron mainly are made of operation control panel and key, matrix control circuit, source of sound integrating device, display drive apparatus, note amplifier and loudspeaker.Broadcast and the accompaniment of key operation and built-in music are only arranged, China Patent Publication No. is the mellotron of 201315151 built-in MP3 player, its operating key and MP3 decoding device all need pass through central processing unit, and circuit structure is complicated, and the MP3 player can not independent play-out work.
Summary of the invention
The purpose of this utility model is to provide a kind of and not only can equally with conditional electronic qin and pianotron have played, but also can adopt the MP3 accompanying song or play separately mellotron and the pianotron with the MP3 playing device of MP3 song.
The utility model, comprise the operation control panel and key, matrix control circuit, source of sound integrating device, note amplifier and the loudspeaker that are electrically connected successively, the source of sound integrating device is electrically connected with display drive apparatus, it is characterized in that described mellotron and pianotron are provided with the MP3 playing device.
The utility model, described MP3 playing device is made of control panel-MP3 operating key, MP3 data-interface and MP3 data processor, the output terminal of MP3 operating key and MP3 data-interface is electrically connected with the input end of MP3 data processor respectively, and the output terminal of MP3 data processor is electrically connected with the input end of note amplifier.
The utility model on described note amplifier, can arrange the audio frequency input/output interface.
The utility model because its MP3 playing device independently arranges, need not can play separately the MP3 song by source of sound integrating device (being central processing unit), and circuit is simple, and is easy to operate.
The utility model, because the MP3 playing device being set in mellotron or pianotron, the MP3 data-interface can be connected with the MP3 player, also can be connected with the USB flash disk that stores the MP3 song, thereby increase the function of mellotron or pianotron, both can with the conditional electronic qin or pianotron was the same play, again can external broadcast MP3 song, also can adopt the MP3 accompanying song.
Description of drawings
Fig. 1 is the block diagram of a kind of mellotron and pianotron with the MP3 playing device of embodiment.
Embodiment
With reference to Fig. 1, a kind of mellotron and pianotron with the MP3 playing device, comprise the operation control panel and key, matrix control circuit, source of sound integrating device, note amplifier and the loudspeaker that are electrically connected successively, on note amplifier, be provided with the audio frequency input/output interface, the source of sound integrating device is electrically connected with display drive apparatus.The difference of the present embodiment and existing mellotron and pianotron is independently to arrange the MP3 playing device, and all the other structures are same as the prior art.Described MP3 playing device is made of control panel-MP3 operating key, MP3 data-interface and MP3 data processor, the output terminal of MP3 operating key and MP3 data-interface is electrically connected with the input end of MP3 data processor respectively, and the output terminal of MP3 data processor is electrically connected with the input end of note amplifier.
