Feature

long: 1520mm    width: 652mm    height: 1230mm
 
key bed with metal frame
The key bed with metal frame is firm and stable, and the keys chassis is not easy to deform in a long period of time.
 
hammer
Germany imported ABEL string hammer with ultraviolet anti-counterfeiting, which is equipped with German VFG hammer felt and is equipped with VFG core felt imported from Germany, and the treble is longer. So the treble is longer.
 
soft sound system
VD3 is equipped with a weak sound file that is beautiful and generous. (the patent number of the said patent for utility model) It has rational angle location and no noise in the tap linkage system. And the adjustable gear of aluminum alloy coated solid wood has better stability.
 
soundboard structure
It is double static angle hexagonal unequal thickness soundboard. The effective vibration area of the soundboard increases the effective vibration area of the middle and high pitches. When the string vibrates, different frequencies resonate with the corresponding regions of the soundboard, and are designed based on the calculated unequal thickness soundboard and arc. This soundboard with different frequencies of vibration resonance effect can be worked.
 
pin block
In order to maintain a suitable torque, high pressure multilayer pin block is made of thickened veneers which is not less than 32 millimeters. It adopts European technology, hard maple, strong adhesive, uniform density. Stainless steel pegs and threading for the process design set precise layout, reasonable expansion pin spacing, uniform torque, to improve the stability of intonation.
 
keyboard felt
The piano keyboard is HAINSWORTH felt from the UK, that the key depth is uniform, so that the piano can be stable in different environments.
 
push-button lock
Its structure is exquisite and novel, and it is easy to operate.
 
built-in type key cover safety device
It's beautiful. The humanized design can protect the playing of dexterous hands.
 
The red and black bicolor black key, spruce solid white key.
The ebony keyboard is not only comfortable, beautiful and natural, but also changes the dynamic and static load of the piano by means of built-in counterweight adjustment.
 
screws and washers
Fastening screw and cylinder washer that use gold and silver suits on the iron plate is fine processing and elegant and pleasing.
Iron rectangular frame structure is made of high-precision vacuum casting. Its source string is firm and stable, and the hole layout is reasonable. Its European carved cast iron plate technology makes the piano more beautiful.
 
assembly of parts
The use of positioning technology in the manufacturing process, which use assembly process of code string soundboard board with a back frame, the back frame with iron plate, the back frame with the shell, makes the piano has been to control assembly.
 
component detail control
We use digital management in the manufacturing process of piano. The iron milling of the string, the formation of the string pillow button hole and the peg hole, positioning hole on back frame and milling soundboard frame and rib groove are made by CNC numerical control machining to make the details of the piano parts are under control.
 
Automatic friction of the string machine weakens the string stress, and ensures a longer and more stable tone.
 
shell surface
The surface of the piano shell side arm, key cover, cover and other parts of the surface are arc type transition, beautiful and generous.
 
isometric design for saddle
According to the effective length and auxiliary frequency resonance principle in chord, treble and bass saddle by consistent times sound assisted chord structure design, the code string force balance.
According to the principle of effective chord length and auxiliary chord multiplier resonance, the sound is more expressive, and the sound quality is close to the grand piano.
 
bass ladder type nut
Bass-zone double-chord group of step-type pillow structure has a fixed chord sine chord pillow button structure strength. It ensures that the effective chord length and chord length of the double-string strings are harmonized, and the noise is reduced.
 
Alto and treble mosaic nut
Alto and treble mosaic nut have different materials.
According to the vibration frequency of different areas, the pillow string of different materials, Hailun makes the alto area voice soft, high pitched sound bright, clear and more diversified.
 
unequivalent dorsal column structure
The beam and inclined frame of VD3 dorsal column remained stable at the piano strings under tension.
 
action
The RENNER technology from German has been widely adopted by Hailun in action.
