Referring to Fig. 1, Fig. 1 shows the structural schematic diagram of guitar, the guitar 300 includes qin body 310 and is fixed on
Six roots of sensation string 3a-3f on qin body 310, wherein the qin body 310 may include body 311, neck 312 and scroll head 313.
Wherein the first end of every string 3a-3f is connected to fixator 100 (shown in Fig. 2) provided by the utility model or 200 (Fig. 4
It is shown) on, wherein the fixator 100 or 200 is fixed on 311 inner cavity S1 of body, the other end of every string 3a-3f is side by side
It is extend out to the outer end S2 along body 311, and extends to scroll head 313 from the neck 312 and is respectively set at the scroll head
Six fixed knobs 314 on 313 and fix, by adjusting the fixed knob 314, string 3a-3f can be made tight or
It unclamps.Driving device can be installed in scroll head 313, driving device drives the work of fixed knob 314 and tenses or loosen string
3a-3f, to change the tension of string 3a-3f.
Referring to Fig. 2, the fixator 100 that Fig. 2 is the utility model first embodiment is fixed in the body 311 of guitar
When structural schematic diagram.The fixator 100 includes supporting element 101, string fixing piece 102 and strain gauge 103,
In, there is mounting surface 315 in the body 311, the supporting element 101 is fixed on the mounting surface in the body 311 of the guitar
At 315 position, the string fixing piece 102 is fixed with the supporting element 101, the quantity of string fixing piece 102 and guitar
String 3a-3f quantity is consistent, and each string is connect with a string fixing piece 102 respectively, and string fixing piece 102 can be set side by side
It sets.
Wherein, the supporting element 101 includes support portion 1011 and interconnecting piece 1012, and the support portion 1011 includes the
On one side 1013 and second face 1014, first face 1013 be reversed with second face 1014, first face 1013 with
The position of the mounting surface 315 is corresponding, and the support portion 1011 can be fixed at mounting surface 315 by screw or viscose.
The interconnecting piece 1012 is connect with the support portion 1011, can be connected vertically.The string fixing piece 102
There is gap between the support portion 1011, and opposite with second face 1014.The setting of strain gauge 103 exists
In gap between the support portion 1011 and the string fixing piece 102.
The end of each string 3a-3f is connected with a limited block 3g, and wherein limited block 3g can be column construction,
On the string fixing piece 102 can be equipped with the matched limiting slot 1021 of the limited block 3g, wherein limiting slot 1021 can be set
In in one side opposite with strain gauge 103 on the string fixing piece 102, it is equipped in the limiting slot 1021 described in supplying
The hole 1022 that string 3a-3f is passed through.When installing string 3a-3f, the limited block 3g being connected on string 3a-3f is limited in
In limiting slot 1021, string 3a-3f passes through the hole 1022, and is pierced by qin from the through hole 3111 being opened on the body 311
Then body 311 is connect with fixed knob 314.
For the ease of the installation of string 3a-3f, the hole 1022 may extend to the side of the string fixing piece 102, shape
At the slot of side openings, during installation, string 3a-3f can slide into the hole from the side openings of string fixing piece 102
In 1022, after tensing string 3a-3f, limited block 3g can be made to be housed in limiting slot 1021.When tensing string 3a-3f, string
3a-3f pulls meeting string fixing piece 102, and string fixing piece 102 occurs certain deformation, applies centainly to strain gauge 103
Pressure, pressure sensor 103 senses string fixing piece 102 to its pressure, and the pressure is converted to electric signal, export to
Processor is handled.
The principle that guitar plays different notes is the vibration frequency for changing string by changing the length of string, wherein qin
The vibration frequency of string can pass through formula:It is calculated, wherein f is the vibration frequency of string, T is value of thrust, and p is
The density of material, L are the length of string.So by the tension at some moment of detection string 3a-3f, can obtain indirectly
With accurate tone corresponding to the tension.And fixator 100 provided by the utility model can be used to fixed string
The tension that string 3a-3f is detected when 3a-3f, when tension value is unsatisfactory for requiring, the controllable drive being arranged on guitar of processor
Dynamic device work, adjusts the tension of string 3a-3f, keeps its tension up to standard, to change tone.
It is understood that in an embodiment of present embodiment, as shown in Fig. 2, the hole 1022 can be opened in institute
The one end of string fixing piece 102 is stated, and the other end of the string fixing piece 102 is then connected on the interconnecting piece 1012,
The string fixing piece 102, interconnecting piece 1012 and support portion 1011 form U-shaped structure, and the strain gauge 103 is located at end
Between the hole 1022 in portion and the interconnecting piece 1012 of end, structure is relatively simple, saves former material.In another implementation of present embodiment
In example, as shown in figure 3, the hole 1022 can be opened in the middle part of the string fixing piece 102, and the string fixing piece 102
Both ends be connected on an interconnecting piece 1012, the interconnecting piece 1012 at both ends is connected on the support portion 1011,
The string fixing piece 102, the interconnecting piece 1012 at both ends and support portion 1011 form frame-shaped construction, in hole 1022 and two companies
Strain gauge 103 is respectively equipped between socket part 1012, using the stress of strain gauge group measurement string 3a-3f, stress is surveyed
It is more accurate to measure.
The shape in the first face 1013 of the support portion 1011 can match with the shape of mounting surface 315, to guarantee
It 1013 is fitted closely on one side with mounting surface 315, for example, the first face 1013 can be plane when mounting surface 315 is plane,
Support portion 1011 can be slab construction, pass in pulling string fixing piece 102 to the stress in this way, can avoid string 3a-3f
When sensor 103 applies pressure, due to leading to measurement inaccuracy between the first face 1013 and mounting surface 315 there are a large amount of gaps.
Viscose further can be filled between the first face 1013 and mounting surface 315, the first face 1013 and installation are filled up by glue
Gap between face 315.
Further, it can be fixed in body 313 using the biggish support portion 1011 of area, guarantee fixator 100
Mounting stability, thus proof stress detection stability.Through-hole 1015 can be offered on support portion 1011, work as string
3a-3f is then passed through through hole 3111 after being then passed through through-hole 1015 behind hole 1022.
Referring to Fig. 4, the fixator 200 that Fig. 4 is the utility model second embodiment is fixed in the body 311 of guitar
When structural schematic diagram.The difference of the utility model second embodiment fixator 200 and first embodiment 100 exists
In the fixator 200 of present embodiment does not have support portion 1011, and strain gauge 103 is the mounting surface directly with body 311
315 fixations, it can be correspondingly applied to present embodiment suitable for the technical solution of first embodiment, in order to avoid weight
It is multiple, it is described into relative to first embodiment difference.In addition, identical with first embodiment or corresponding component is adopted
With appended drawing reference corresponding with first embodiment, for example, in the first embodiment, the label of strain gauge is, that
In the present embodiment, the label of strain gauge is that other component is similar.
The supporting element 201 of the fixator 200 of present embodiment does not include support portion 1011, and the supporting element 201 can be equal
For the interconnecting piece 1012 in first embodiment.One end of the supporting element 201 is fixed on the mounting surface 315 of body 311,
The other end of the string fixing piece 202 then with supporting element 201 is fixed, and can form bridge shape (as shown in Figure 4) or shape is at L-shaped (such as
Shown in Fig. 5).Strain gauge 203 is set up directly in the gap between mounting surface 315 and string fixing piece 202.This implementation
The fixator 200 of mode can preferably be suitable for the installation of the stringed musical instrument of small complex structure, reduce sky shared by fixator 200
Between.
