Summary of the invention
The object of the present invention is to provide a kind of string device for measuring force, to 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 string device for measuring force, comprises housing, wherein, is provided with five case partitions in housing, and housing inner chamber is divided into six cavitys, and 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 hole; Tension spring, through the spring eye on housing, is arranged in housing; On tension spring, be provided with pcb board, on pcb board, be 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 is used for adjusting tension spring position, so that better for string adjustment.
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, after under tension, can be out of shape, elongate, the diameter of tension spring material used, pulling force, pulling strengrth are determined by Experimental Comparison, according to string, strain the S type tension spring that required value of thrust is manufactured corresponding size.When tension spring is in the process of tuning a stringed instrument by knob, while being stretched to corresponding length, displacement transducer can send corresponding electric signal, and circuit can be triggered, and hummer can be sounded to point out and be regulated and put in place.
This beneficial effect of the invention is: this invention utilizes before string sounding, string need to be tightened, and while reaching certain value, just can produce correct sound.Utilize the principle of tensile force, near string adjusting knob or the other end of string, electronics device for measuring force of design and installation, when string reaches certain pulling force, just can make string send correct sound, reaches 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, to better understand the present invention.
Embodiment
A tensile test box is set in the position of scroll head, and box upper and lower side respectively stretches out six pulling force heads (take guitar as example), by this pulling force box, can test out the pulling force that string is subject to.
The string device for measuring force being illustrated in fig. 1 shown below, comprise housing 1, in housing 1, be provided with five case partitions 10, housing 1 inner chamber is divided into six cavitys, housing 1 bottom is provided with six spring eyes 11, as shown in Figure 3, in six cavitys of housing 1, be separately installed with six tension springs 2, 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 hole 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 tops are provided with screw thread 14, and bottom is provided with joystick knob 15.Knob 5 is for adjusting tension spring 2 positions, so that better for string adjustment.
In housing 1, set after tension spring 2, pcb board 3 is installed on tension spring 2, on pcb board 3, be 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 sides, 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.
