Description

Keyboard is played in a kind of computer music special use

Technical field

Present technique relates to a kind of physical construction of piano type keyboard, is specifically related to a kind of computer music special use and plays keyboard.

Background technology

Along with computer hardware and Development of Multimedia Technology, music softwares such as spectrum, computer music, music are synthetic, virtual musical instrument have appearred painting such as: computer.Their appearance makes computer become a powerful musical performance, authoring tools.Particularly after the logical company of wound releases " sound word " technology, Computer Music player can download the musical instrument kind total amount that computer is enriched in the instrument tamber storehouse have different musical instrument expression effects in a large number from Internet, this technology makes multimedia computer can show audio true to nature as more than 100 kind of musical instruments such as piano, organ, violin, guitar, basses, has strengthened the learning recreation function of computing machine greatly.These have replaced expensive traditional instrument with the virtual musical instrument that form of software exists, and make people just can carry out the study and the amusement of various musical instruments on computers with very little cost.But, since above-mentioned software normally with computer keyboard as the note input tool, and there are structural notable difference in computer keyboard and button keyboards for musical instruments, and the play fingering as piano that causes the user to utilize to have grasped is played on computer keyboard.Same reason also makes the music beginner practise correct key play fingering by computer keyboard, causes in fact the waste of computer CPU computational resource and relevant music function thereof with idle.

The utility model mainly provides a kind of combination button formula music keyboard that is used with software of computer music, the key external form of this music keyboard and alignment placement and piano are similar, do not influence the custom of playing of being familiar with piano playing fingering person, guaranteed that also the beginner can practise with correct piano playing fingering on the utility model, and after on top of, can directly play piano and mellotron.

Summary of the invention

In order to overcome the deficiency that the active computer keyboard can not be used for music playing, the utility model provides a kind of computer music special use to play keyboard.This music keyboard can not only be applied to music software supporting play keyboard, and can allow the user replace key easily with different colours, material.

The technical scheme that its technical matters that solves the utility model adopts is: solve the problems referred to above by the physical arrangement that re-constructs computer keyboard.Because keyboard is the indispensable input tool of computing machine, and its inside comprised the matrix-scanning circuit, therefore is equipped with the sweep circuit of said function when the new combination button formula Computer Music keyboard of design no longer separately.The utility model has been taked the method for " using ", by little on each key being touched in the switch matrix circuit that switch is linked into computor-keyboard in the corresponding a certain key scan loop, finish computer to 88 key key positions and to the identification of actuation of keys, realize the functional transformation of computor-keyboard to music keyboard.

The purpose of this utility model be achieved in that a kind of detachable key the computer music special use play keyboard, comprising: 1. substrate, J-1, J-2, the white key of J-3, J-4., J-5. black key, 4. bar shaped stage clip, 5. little switch that touches, 6. diplopore cable plug, 7. lead, 8. jack, 9. damping cushion, 10. stitch, 11. groove, 12. breach, 13. leadout holes.In each key rear end one jack is arranged, this jack by the key body after free end along the key axon to extending internally, the free end shape of jack shape and bar shaped stage clip is out of true coupling, relies on the friction force of both surface of contact to make whole key body be socketed in the free-ended surface of bar shaped stage clip securely after bar shaped stage clip free end is inserted this jack.Like this, be convenient to when needed the user take out the key body replace to have different colours, the key of material, compare with the outward appearance of conventional keyboard musical instrument, the utility model keyboard overall appearance can be adjusted according to different users's aesthetic preference, makes keyboard appearance have more the personal characteristics.

Another purpose of the present utility model is to provide a kind of little switch that touches that is used with key, it is characterized in that: little touching in the groove that switch is fixed on key bottom, little two stitch that touch switch self are crooked and extend to outside the groove, and as conductive plug be plugged on its lip-deep diplopore cable plug and be electrically connected, the advantage of this structure is: in assembling qin body or use, the diplopore cable plug can be inserted in the little stitch that touches switch of other keys to change the keyboard circuit scan code of key representative, adjust by the sound preface confusion that different set caused of different music softwares to the note operating key.The lead that diplopore cable plug rear portion is drawn is linked in a certain key scan loop of keyboard matrix on-off circuit, promptly finishes single key is connected with the communication of host computer.Touch the scan loop that switch inserts each respective keys with all keys are little successively, promptly can be used as happy keyboard of standard pronunciation and music software and be used.When the key pressurized move down and with substrate contacts after, trigger the little switch that touches in the groove.Littlely touch the scan loop conducting immediately that switch forms with this, and produce a control control signal and be sent to computing machine, detect the keyboard scancode of this signal representative by music software after, the control audio amplifier send out one with the corresponding happy symbol sound of this key.

Another purpose of the present utility model is to provide a kind of bar shaped stage clip group that key can be pumped, it is characterized in that: two row horizontally were fixed in a side of substrate about described bar shaped stage clip group was, its free end of the bar shaped stage clip of top delegation inserts in the hole of Bai Jianzhong correspondence, below its free end of bar shaped stage clip of delegation insert in the hole corresponding in black key.In use, make the bending of bar shaped stage clip by pushing the key that is positioned at its free end downwards, key moves downward thereupon, is fixed in little switch that touches in the groove until touching substrate and triggering the key bottom.When finger lifted, crooked bar shaped stage clip returned to original position with the key that is positioned at its free end under the effect of self elastic force.The advantage of this structure is: simplified the key gear train greatly, and do not had the mechanical friction of drive disk assembly, the long-time positional precision that also can not change each key of using.

The beneficial effects of the utility model are, keyboard is played in a kind of computer music special use of practicality, and its total movement parts are two row bar shaped stage clip groups, and are simple in structure, are convenient to install and make.To the substitute of traditional instrument such as expensive piano and mellotron, by being used the piano and the high-grade mellotron of alternative costliness with multimedia computer, is a kind of popular musical instrument exercise instrument of crossing the threshold as average family.
