The object of the present invention is to provide a kind of string device for measuring force, can help better to regulate string, make it simple to operate clear, easy to use.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of string device for measuring force, comprise housing, wherein, be provided with five case partitions in housing, housing cavity be divided into six cavitys, housing bottom is provided with six spring eyes, in six cavitys of housing, is respectively arranged with six tension springs; Housing bottom is provided with string access aperture; Tension spring, through the spring eye on housing, is arranged in housing; Tension spring is provided with pcb board, pcb board is provided with button cell, hummer and displacement transducer; Tension spring is provided with knob at hull outside top; Pcb board arranged outside has lid.
Further, tension spring is designed to S type, and there are upper boom and lower beam in centre.
Further, knob top is provided with screw thread, and bottom is provided with joystick knob.Knob for adjusting tension spring position, to adjust for string better.
Further, the probe of displacement transducer is arranged in the S type upper boom of tension spring or the cavity of lower beam side, and displacement transducer is connected with hummer by circuit, and displacement transducer is connected with button cell.
In this invention, tension spring becomes S type, has certain elastic force, can be out of shape after under tension, elongate, the diameter of tension spring material used, pulling force, pulling strengrth are determined by Experimental Comparison, manufacture the S type tension spring of corresponding size according to the required value of thrust of string tension.When tension spring by knob in the process of tuning a stringed instrument, when being stretched to corresponding length, displacement transducer can send corresponding electric signal, and circuit can be triggered, and hummer prompting of sounding has regulated and puts in place.
This beneficial effect of the invention is: before this invention utilizes string sounding, needs string to tighten, and when reaching certain value, just can produce correct sound.Utilize the principle of tensile force, near string adjusting knob or the other end of string, design and installation electronics device for measuring force, when string reaches certain pulling force, just can make string send correct sound, reach the effect of tuning.The present invention distinguishes the mode of existing survey string frequency, and easy to adjust, result of use is simple and clear.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described, better to understand the present invention.
Embodiment
Arrange a tensile test box in the position of scroll head, box upper and lower side respectively stretches out six pulling force heads (for guitar), can test out by this pulling force box the pulling force that string is subject to.
The string device for measuring force be illustrated in fig. 1 shown below, comprise housing 1, in housing 1, be provided with five case partitions 10, housing 1 lumen segmentation is become six cavitys, six spring eyes 11 are provided with bottom housing 1, as shown in Figure 3, in six cavitys of housing 1, six tension springs 2 are separately installed with, the concrete pattern of tension spring 2 is shown in Fig. 4 and Fig. 5, be designed to S type, there are upper boom 12 and lower beam 13 in centre, and bottom is provided with string access aperture 9; Tension spring 2, through the spring eye 11 on housing 1, is arranged in housing 1.
Tension spring 2 is provided with knob 5 in housing 1 outside top, and the pattern of knob 5 is shown in Fig. 7, and knob 5 top is provided with screw thread 14, and bottom is provided with joystick knob 15.Knob 5 for adjusting tension spring 2 position, to adjust for string better.
Set tension spring 2 in housing 1 after, tension spring 2 is provided with pcb board 3, pcb board 3 is provided with button cell 7, hummer 8 and displacement transducer 6, as shown in Figure 6.The probe of displacement transducer 6 is arranged in the S type upper boom 12 of tension spring 2 or the cavity of lower beam 13 side, displacement transducer 6 is connected with arithmetical unit, arithmetical unit is connected with hummer 8, and displacement transducer 6, arithmetical unit are connected with button cell 7, as shown in Figure 9.
