Abstract
The invention relates to an easily adjustable type string force measuring device and belongs to the technical field of auxiliary musical instrument tuning technology. The device comprises a housing. Six tension springs are arranged inside the housing. The bottom of the housing is provided with a string access hole. The tension springs pass through spring holes inside the housing to be installed inside the housing. The tension springs are provided with a PCB. The PCB is provided with a button battery, a buzzer and a displacement sensor. The tops of the tension springs, on the outer side of the housing, is provided with a knob. The outer side of the PCB is provided with a cover body. According to the technical scheme of the invention, before the sound production of strings, the strings are tightened at a certain degree so as to produce correct sounds. Based on the principle of the tensioning force, an electronic force-measuring unit is arranged nearby the string adjustment knob or at the other ends of strings. When the tensile force on strings reaches a certain value, the strings are enabled to produce correct sounds. Therefore, the string tuning effect is realized. Different from the existing string frequency measurement manner, the above device is convenient in adjustment, and simple and clear in usage effect.
Description
The present invention is the applying date is " on December 03rd, 2013 ", application number is the divisional application that " 201310638297X ", name are called the application for a patent for invention of " string device for measuring force ".
Technical field
The present invention relates to a kind of string device for measuring force, belong to melody auxiliary implement technical field.
Background technology
Currently used stringed musical instrument, such as guitar, it is necessary to often tuning, the reason causing tuning is, the string tonequality caused that fluffs is forbidden, and the variator on market is all by sounding of manipulating the strings, by judging that the frequency of sound adjusts tonequality, the product of use is " electronic tuning device ".
Summary of the invention
It is an object of the invention to provide a kind of string device for measuring force that can easily be accommodated, so as to help better to regulate string so that it is simple to operate clear, convenient use.
To achieve these goals, technical scheme is as follows.
A kind of string device for measuring force that can easily be accommodated, including housing, is provided with five case partitions in described housing, housing cavity is divided into six cavitys, described housing bottom is provided with six spring eyes, in six cavitys of housing, is respectively arranged with six tension springs; Shown housing bottom is provided with string access aperture; Described tension spring is arranged in housing through the spring eye on housing; Described tension spring is provided with pcb board, described pcb board is provided with button cell, buzzer and displacement transducer; Described tension spring is provided with knob at hull outside top; Described pcb board arranged outside has lid; Described knob top is provided with screw thread, and bottom is provided with joystick knob, and knob is used for adjusting tension spring position; Described tension spring is in the process that knob is tuned a stringed instrument, and when being stretched to corresponding length, displacement transducer can send corresponding electric signal, and circuit can be triggered, and buzzer can send auditory tone cues and regulate and put in place.
This beneficial effect of the invention is in that: before this invention utilizes string sounding, it is necessary to tightened by string, when reaching certain value, just can produce correct sound. Utilizing the principle of tensile force, near string adjusting knob or the other end of string, one electronic, horological power apparatus of design and installation, when string reaches certain pulling force, so that it may so that string sends 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.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described, in order to be better understood from 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 string tension by this pulling force box.
The string device for measuring force being illustrated in fig. 1 shown below, including housing 1, in housing 1, it is provided with five case partitions 10, housing 1 lumen segmentation is become six cavitys, six spring eyes 11 it are provided with bottom housing 1, as it is shown on 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, being 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 is used for adjusting tension spring 2 position, in order to better for string adjustment.
After setting tension spring 2 in housing 1, tension spring 2 is provided with pcb board 3, pcb board 3 is provided with button cell 7, buzzer 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 was connected with arithmetical unit, arithmetical unit is connected with buzzer 8, and displacement transducer 6, arithmetical unit are connected with button cell 7, as shown in Figure 9.
After installing tension spring 2, being provided with pcb board 3 and connect circuit, close cover plate 4, and the pattern after lid is shown in Fig. 2. Whole device is arranged in qin holder 16, sees accompanying drawing 8.
Tension spring 2 one-tenth S type, has certain elastic force, can deform after under tension, elongates, and the diameter of tension spring 2 material used, pulling force, hot strength are determined by Experimental Comparison, manufactures the S type tension spring 2 of corresponding size according to the required value of thrust of string tension.
When tension spring 2 by knob 5 in the process tuned a stringed instrument, when being stretched to corresponding length, displacement transducer 6 can send corresponding electric signal, and displacement transducer 6 can receive the distortional elastomer signal of six roots of sensation string 17, the current value that the output of different distortion amount is different.This value feeds back to comparison in arithmetical unit. When reaching preset value, exporting signal arithmetical unit, buzzer 8 sends sound, and prompting has regulated and put in place.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
