Abstract
The invention relates to a string tension measurement device with a buzzer and belongs to the technical field of auxiliary tuning for musical instruments. The device comprises a housing and six tension springs are arranged inside the housing; the bottom of the housing is provided with string inlet holes; the tension springs pass through spring holes on the housing and are installed inside the housing; a PCB is arranged on the tension springs, and the PCB is provided with a button cell, a buzzer and a displacement sensor; the top parts, outside of the housing, of the tension springs are provided with turn knobs; the outer side of the PCB is provided with a cover body. According to the device, the strings need to be tensioned before giving off sound, and when the tension reaches a certain value, the strings will give off the right sound. By use of the principle of tensile force, an electronic tension measurement device is designed and installed around string adjusting knobs or on the other side of strings; when the tension of strings reaches to a certain value, the strings will give off the right sound and therefore toning effect is realized. The way of the device for measuring string frequency is different from those of the present devices; the device is easy to operate for toning, and the using effect is simple and clear.
Description
The divisional application that the present invention is the applying date is " on Dec 03rd, 2013 ", application number is " 201310638297X ", name is 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
The stringed musical instrument of current use, such as guitar, need frequent tuning, cause the reason of tuning to be, the string tonequality caused that fluffs is forbidden, and the organ stop 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
The object of the present invention is to provide a kind of string device for measuring force with hummer, 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.
There is a string device for measuring force for hummer, comprise housing, in described housing, be provided with five case partitions, 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, hummer and displacement transducer; Described tension spring is provided with knob at hull outside top; Described pcb board arranged outside has lid; Described tension spring is designed to S type, and there are upper boom and lower beam in centre; Described knob top is provided with screw thread, and bottom is provided with joystick knob, and knob is for adjusting tension spring position; The probe of institute's displacement sensors 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.
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.
