Abstract
A kind of smart bluetooth electronic keyboard system, comprises Bluetooth electronic piano key board device and intelligent terminal.Described Bluetooth electronic piano key board device and described intelligent terminal carry out data communication by the radio signal of Bluetooth protocol.In Bluetooth electronic piano key board device, processor circuit is connected with push-button array circuit, bluetooth transmission circuit, LED light array circuit respectively, and battery and feed circuit are connected with processor circuit, push-button array circuit, bluetooth transmission circuit, LED light array circuit respectively.The inner integrated with Bluetooth module of intelligent terminal, loudspeaker or earphone interface, be provided with application software.When user presses black key on Bluetooth electronic piano key board device or white key, Bluetooth electronic piano key board device gathers key information, and sends to intelligent terminal with Bluetooth radio signal.After this key information of intelligent terminal for reception, its application software displaying audio file, eventually through loudspeaker or the earphone interface output mellotron sound equipment of intelligent terminal.
Description
Technical field
The utility model relates to a kind of mellotron musical instrument, and especially a kind of Bluetooth radio signal that uses carries out data communication, plays the intelligent electric musical instrument system of mellotron sound equipment by intelligent terminal and application software thereof.
Background technology
At present, general mellotron, by output audio signal after processor acquisition keypad key press information, carries out power amplification by its internal amplification circuit, exports mellotron sound equipment eventually through loudspeaker.In order to provide display information, need independent display screen; Except the button for playing, need many buttons for function setting are installed; In order to improve acoustics, need the processor chips that usability is stronger; In order to integrated various preset acoustics and melody storehouse, need to use jumbo memory chip.These all make the manufacturing cost of mellotron higher, and physical dimension is larger.In addition program and music information are all solidificated in storage chip in the mode of firmware, are also unfavorable for system upgrade.
Summary of the invention
In order to make the manufacturing cost of mellotron lower, man-machine interaction is more intelligent, use lighter, upgrade software is more flexible, stand-by time is longer, the utility model uses blue teeth wireless interconnection technique, by the existing Audio Signal Processing of intelligent terminal and broadcasting, massive store, power amplification function, sends mellotron sound equipment by the loudspeaker of intelligent terminal inside or earphone interface.Realize friendly man-machine interaction by the display screen on intelligent terminal and application software simultaneously.
The technical solution adopted in the utility model is as follows: the utility model is made up of Bluetooth electronic piano key board device and intelligent terminal.Bluetooth electronic piano key board device and intelligent terminal carry out data communication by bluetooth radio.Described Bluetooth electronic piano key board device comprises: push-button array circuit, LED light array circuit, processor circuit, bluetooth transmission circuit, battery and feed circuit.Push-button array circuit is for gathering mellotron black key, white key information.When staff pushes button, the key information of correspondence is passed to processor circuit by push-button array circuit, and processor circuit is sent to bluetooth transmission circuit this information again, and sends with radio signal.Battery and feed circuit can provide power supply for the push-button array circuit in Bluetooth electronic piano key board device, LED light array circuit, processor circuit, bluetooth transmission circuit.Described intelligent terminal is existing device, can be a smart mobile phone, or an Intelligent flat, or an intelligent TV set.Intelligent terminal is integrated with bluetooth module, can install application software, integrated loudspeaker or earphone interface, and can displaying audio file, has the display screen of man-machine interaction.The integrated bluetooth module of intelligent terminal receives the radio signal from Bluetooth electronic piano key board device, this information is delivered to the application software being arranged on described intelligent terminal by bluetooth module again, application software receives this information and plays the audio file of corresponding key information, exports mellotron sound equipment eventually through loudspeaker on intelligent terminal or earphone interface.Can to the volume of mellotron by the human-computer interaction interface of application software, tone color, rhythm, accompaniment etc. is arranged, and can send the mellotron sound equipment of different-effect according to the different intelligent terminal arranged.Described Bluetooth electronic piano key board device is provided with the black key of arrangement mode the same as conditional electronic qin, white key board, is placed with a LED light below at each black key or white key.Application software on described intelligent terminal can read and after resolving the file of midi format, obtain the musical alphabet in each track and beginning and ending time information thereof.Application software sends according to the initial of each musical alphabet or end time the bluetooth module of order to described intelligent terminal lighting or extinguish LED light.Bluetooth transceiver module in Bluetooth electronic piano key board device by this order of reception, and is forwarded to its internal processor circuitry, and processor circuit obtains this order and controls lighting or extinguishing of corresponding LED light afterwards.
The beneficial effects of the utility model are, by the existing Audio Signal Processing of intelligent terminal and broadcasting, massive store, power amplification function, export mellotron sound equipment by the loudspeaker of intelligent terminal or earphone interface.Eliminate the display screen in conditional electronic qin, be used as the keyboard of function setting, the development again of mass storage, high performance audio processor circuit, power amplification circuit, loudspeaker, thus make manufacturing cost lower.Its advantage also has: simple and light, stand-by time is longer, and man-machine interaction is more intelligent, can online upgrading application software.By the LED light on keyboard, the function of teaching or game can also be realized.
