Specific embodiment
Referring to Fig.1 shown in -9, novel digital fingerboard of the invention, including keyframe 1, the keyframe 1 is by multiple keyframves
Module 19 is formed by connecting, and is connected between the key frame module 19 by the metal connecting plate 20 of bottom.For make key frame module 19 it
Between connect between stronger and smooth, adjacent key frame module 19 by dovetail groove 21, dovetails 22 be cooperatively connected it is (i.e. previous
The dovetails of a key frame module are inserted into the dovetail groove of the latter key frame module).1 upper end of keyframe is equipped with one group of (standard
88 keys, can also 61 keys, 49 keys etc.) white key 2 that is arranged alternately, black key 3,1 lower end of keyframe is equipped with 4, one groups of weights of pcb board
5, the white key 2, black key 3 press press-fit by the stationary contact 7 on compression leg 6 and pcb board 4 by bottom, and the weight 5 is white key
2, black key 3 provide counterweight (gravity pressed down and reset), 5 upper end of weight be rotatably installed on the keyframe 1 and
First surface 8 is equipped at the top of the weight 5, the white key 2,3 bottom of black key are equipped with the second song cooperated with the first surface 8
Face 9 when playing the white key 2, black key 3, carries out face contact between the first surface 8, the second curved surface 9, the weight also leads to
Cross the first surface to state white key 2, black key 3 apply gravity.
Further, the weight 5 is mainly made of weight linear meter 51, mounting rack 52, Rubber end 53, on the weight linear meter 51
End is arranged on mounting rack 52, and 51 top of weight linear meter is arranged in the Rubber end 53, is arranged first on the Rubber end 53
Curved surface 8, the weight 5 are rotatably installed on the keyframe 1 by mounting rack 52.By the design of mounting rack, in order to
The Fast Installation of weight and mounting rack.By the design of Rubber end, forms and be convenient for changing convenient for the design of first surface, simultaneously
Rubber end has certain elasticity, at runtime, " feel " more preferably.
Further, one group of spaced first mounting post 10, first mounting post 10 are equipped in the middle part of the keyframe 1
On be equipped with axis 11, the mounting rack 52 of the weight 5 is erected in first mounting post 10, and pass through the first groove 12 and institute
Axis 11 is stated to be rotatably assorted.By above structure, the replacement of weight can be very easily realized, can be needed conveniently according to customer
Different " feel " of realization.
Further, one group of spaced second mounting post 13, second mounting post 13 are equipped at the top of the keyframe 1
On be equipped with axis 11, the white key 2, black key 3 top be erected in second mounting post 13, and by the second groove 14 with
The axis 11 is rotatably assorted, and by above structure, can very easily realize the replacement of white key, black key.Due to white key, black key
It is convenient for disassembly and assembly, further facilitated the dismounting of weight.
Further, the hook 25 of the white key 2,3 bottom of black key equipped with a pair of opposing passes through the hook 25 and mounts
In 51 top of weight linear meter, play to the weight positioning action, to prevent its from deviating from the position.
Further, the stationary contact 7 on the pcb board 4 is arranged by space before stationary contact 71, middle stationary contact 72, rear quiet
Contact 73 forms, described by rubber mat 15 is arranged between compression leg 6 and the stationary contact 7 of the pcb board 4, is arranged on the rubber mat 15 high
The incremental preceding movable contact 16 of degree, middle movable contact 17, late contact 18, the preceding movable contact 16, middle movable contact 17, late contact 18
It is engaged respectively with stationary contact 71, middle stationary contact 72, rear stationary contact 73, the rubber mat 15 is preceding movable contact 16, middle movable contact
17, late contact 18 provides elastic force, can reset.Pass through the different conducting resinl contact design of three height, these three contacts
Meeting corresponding route of triggering and conducting when key is pressed into different depth.By taking white key as an example, first point (i.e. preceding stationary contact
It 71) is probably to be pressed at about 5mm to be connected in key, second point (stationary contact 72 in i.e.) is about at 7mm, third
Point (stationary contact 73 after i.e.) is about at 9mm.Whole strokes of the white key of general keyboard are about 10.8mm.Key is pressed on earth
Afterwards, hand is unclamped again, above three contact can successively be unclamped since third contact again.After first point triggers, route is temporary
When be held on;After second point triggering, CPU starts timing, to after the triggering of third point, obtains a time difference, such as
More than ten milliseconds.At this moment, a dynamics signal, the intensity that CPU is pronounced with this signal processing are just given.Then, it is opened after key bottoms out
Beginning rebound stroke: being first to unclamp third contact first, then when key, which goes back up to second contact, to be unclamped, if being placed on biography
Unite two contacts keyboard when, sound is shut off, and three contacts is quite different, as long as key goes back up to cutting first not yet
The position of a contact, sound would not be cut off, this section is probably between 5-7mm, and at this time bullet goes down again, and can be issued
One musical sound.Namely quickly connect the effect of bullet.
Further, foam-rubber cushion 23 is equipped between the weight linear meter 51 and the contact surface of keyframe 1, for absorb weight linear meter
Shock sound between keyframe.It is equipped with felt 24 between the white key 2, black key 3 and the contact surface of keyframe 1, is pressed for absorbing
Shock sound between button and keyframe.It is finally reached the effect of noise reduction.
It is upper described, limitation in any form not is done to the present invention, although the present invention is with the announcement of preferable case study on implementation
As above, however, it is not intended to limit the invention, any person skilled in the art, is not departing from technical solution of the present invention model
In enclosing, when the structure and technology contents using the disclosure above make a little change or are modified to the equivalence enforcement of equivalent variations
Case, but anything that does not depart from the technical scheme of the invention, according to the technical essence of the invention to the above case study on implementation institute
Any simple modification, equivalent change and modification of work still belong to technical solution of the present invention range.
