Description
Technical field
The present invention relates to a kind of musical instrument, is a kind of piano particularly.
Background technology
Piano is derived from a kind of keyboard instrument in western classical music, is made up of, drills 88 keys and metallic cord soundboard
The person of playing is by by the key on lower keyboard, affecting the gavel that carpet is enclose inside piano, then tapping steel wire string and send sound.
Piano is because of its broad range, beautiful tone color absolutely, is referred to as the king of musical instrument；For ordinary people, by observing and practicing repeatedly
Habit can grasp playing skill, but for blind person, because vision is obstructed, can not intuitively position the button of piano, because
This learning difficulty is larger；Simultaneously again because piano has extremely more buttons, this causes learning difficulty further to increase.
The content of the invention
In view of the above-mentioned problems, the present invention, which provides a kind of blind person, aids in piano, the piano construction is novel, principle is unique, can
Easily assisting blind positioning key, helps blind userses self-learning piano, and the intuitional and experiential thinking of teach-by-doing teaching type is provided for blind person,
Effectively improve learning efficiency.
To solve the above problems, the technical solution adopted in the present invention is：This blind person aids in piano to include body and qin
Key, the key include 52 white keys and 36 black keys；
Central processing unit is installed in the body, coffret is provided with the central processing unit；
Sensing chip is provided with the upper surface of each key, each sensing chip is electrically connected with the central processing unit；This blind person
Auxiliary piano also includes auxiliary fingerstall, the auxiliary piece aided on fingerstall and central processing unit wireless pairing；
The front portion of the panel of the key is provided with accessory plate, two auxiliary units are installed on the accessory plate, each
Auxiliary unit includes the driving groove opened up on the auxiliary board, and transmission belt, the transmission are provided with the inside of the driving groove
Band is driven by driving cylinder and rotated；
Between the both sides cell wall of the driving groove, control shaft is equidistantly placed with, sensing ball is arranged with each control shaft,
Sensing brush is installed on each sensing ball and controller, the controller are electrically connected with the central processing unit；The sensing
Brush reciprocally swinging, the controller can contact under the control of central processing unit in the case where pointing to the drive of ball or away from transmission
Band.
The beneficial effects of the invention are as follows：When practising piano, user will aid in being set in ten hands corresponding to fingerstall
On finger；It is transferred to from coffret by the program for music score of imparting knowledge to students in central processing unit, central processing unit is by corresponding to each syllable
Signal is delivered separately to sensing chip and aids in the auxiliary piece on fingerstall, and sensing chip is activated successively according to the sequencing of syllable,
When previous syllable is played, latter syllable can just start；Auxiliary piece stimulates corresponding hand successively according to the sequencing of syllable
Refer to, when finger is correctly pressed against corresponding key, the stimulation terminates, and starts the stimulation to next finger；In auxiliary piece
Under the cooperation of sensing chip, music can be come by slow, orderly playing out, and user can become familiar with and just by repeating
Normal performance comes out.
The piano difficulty of blind userses exercise is accurately find corresponding key, in the present invention, central processing
The control driving cylinder and controller motion that device can match while signal is passed into sensing chip and auxiliary piece, specific control
Method is as follows：Under nature, each controller is kept away from not contact condition with transmission belt, and now pointing to ball can control
Rotated freely on axle, under gravity, controller keeps straight down, pointing to brush and then holding up upwards, user places wrist
In initial position, brush is pointed in now wrist compressing, and can perceive sensing brush waves direction；Bullet is treated when a syllable transmits out
When playing, sensing chip and auxiliary piece continuous firing；Central processing unit control driving cylinder drives transmission belt directional rotating, while centre
Controller ejection and Contact Transmission band in reason device driving " particular range "；When playing first syllable, " particular range " be
Scope between referring to from wrist initial position to the position of syllable to be played, when playing non-first syllable, " particular range "
Refer to from upper monosyllabic position to the scope between the position of syllable to be played；
The controller of ejection contacts with transmission belt, and the experiencing small oscillating movements under the drive of transmission belt, and now controller, which drives, points to
Ball and sensing brush rotate to an angle around control shaft, now point to brush and tilt certain angle towards fixed-direction, " particular range " it is interior
The inclined brush that points to specifies the azimuth-range that wrist should move for user, and blind userses are according to the incline direction for pointing to brush
Mobile wrist, and keep finger to be slided on key, behind wrist in-position, the inclined brush and vertical of pointing to can be experienced
Sensing brush between boundary, and then stop mobile wrist, by the mobile finger stimulated by auxiliary piece, find sense to be pressed
Answer piece, and then key corresponding to springing.
To sum up, the present invention carries out two-part guide to blind userses, and one：Instruct wrist significantly mobile exercise wrist fortune
It is dynamic, two：User's fingering and gesture are instructed by auxiliary piece and sensing chip；Allow users to accurately study and grasp key
The mobile range of scope, wrist, and the utilization of fingering；Even if dysopia be present, it is also possible that blind userses are calm, high
The study piano of effect；The structure of the present invention is novel, principle is unique, and ten fingers of blind person have auxiliary piece guidance, this accurately to refer to
Lead as have teacher by doing and illustrating teaching student how to press finger, with fingering, and then greatly improve training accuracy, efficiently
Property, contribute to blind userses quickly to grasp pianism, be that blind userses hew out new road in the music world.
