Realized above-mentioned technical scheme, just can reach and not destroy the keyboard instrument structure, do not influenced under the prerequisite of primary characteristic index, be installed in easily on the keyboard instrument, can reappear automatically and play according to the song signal of prior storage.
Description of drawings
Fig. 1 is the utility model schematic block diagram;
Fig. 2 is the sectional view of the utility model when being installed on the piano key face;
Fig. 3 is the vertical view of the utility model when being installed on the piano key face.
Specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing,, can clearerly find out and understand advantage of the present utility model place by description to the utility model preferred embodiment.
As Fig. 1, storer, control terminal are connected on the microprocessor, and driver module also is connected on the microprocessor, and microprocessor connects power supply simultaneously, and driver module connects calutron to accept the action of instruction control calutron.In the use, the effector passes through the control terminal control microprocessor in advance from the external record playing procedure, it can be recording to player's playing procedure, it also can be the music file that input is made, microprocessor is converted into stored into memory after the digital signal with these file processing, and microprocessor is connected to power supply with work.Usually above-mentioned storer is erasable, and not erasable storer also can be realized the utility model purpose certainly.When needs reappeared performance, the effector handled control terminal, and control microprocessor is called the music file that storer is stored in advance, according to default algorithm controls driver module.Driver module then turn-offs processing with the Control current size according to the instruction of microprocessor to a plurality of calutrons.Thereby make electromagnet in a plurality of calutrons according to the record of music file, knock key, duplicate automatically and perform music with certain dynamics and time.
As Fig. 2, when the keyboard instrument that needs automatic playing was piano, the keyboard that opens the piano lid lid 12 was installed on shell 18 on the key face of piano, and the length of the length of shell 18 and piano key face adapts.Be provided with calutron 14 in the shell 18, two row's solenoids before and after dividing, black key 10 and the white key 20 with piano is corresponding one by one respectively for two row's solenoids, a plurality of electromagnet elasticity on the calutron 14 are connected in a plurality of solenoids, size and key coupling with the surface of contact of black key 10 and white key 20, assurance can be knocked the string sounding on the key downward motion striking pallet 22, can not influence other keys again.The motion of calutron 14 is subjected to the control of driver module 16, driver module 16 is provided with and is fixedly mounted in the shell 18, be connected with calutron 14, and be connected with control store, according to the instruction of control store, the electric current of a plurality of solenoids in corresponding shutoff or the change calutron 14, thus a plurality of electromagnet in the calutron 14 are moved up and down with certain dynamics and time, knock black key 10 and white key 20 motion sounding, automatic playing.
As Fig. 3, when being the automatic playing piano equally, can clearerly find out the one-to-one relationship of a plurality of solenoids and piano black key 10 and white key 20 in the calutron 14.
In Fig. 2 and Fig. 3, control store can be connected control with wireless mode with automatic player, also can be that line traffic control connects.
In Fig. 2 and Fig. 3, all be to be example with the piano, but any keyboard instrument can adopt the utility model to carry out automatic playing, grant the embodiment basically identical of piano in fact, except the row according to corresponding keys pan musical instrument keyboard key counts difference, and in calutron 14, be provided with outside the solenoid of respective row number, other are in full accord, repeat no more here.
Here it is to be noted: those of ordinary skill in the art can make various suitable distortion or replacement on basis of the present utility model, but all these distortion or replacement all should belong to protection domain of the present utility model.
