Embodiment 1

[0054] The brocade thread life tester 5 provided by the present invention can clamp the brocade thread and provide a magnetic field during the brocade thread life test.

[0055] See figure 1 As shown, the brocade thread life tester 5 includes an upper magnet bracket 51 and a lower magnet bracket 52 . Wherein, described upper magnet support 51 and described lower magnet support 52 are arranged relatively, all can place magnet on upper magnet support 51 and lower magnet support 52, the magnet placed on upper magnet support 51 and lower magnet support 52 can A magnetic field is generated in the spatial region between the upper magnet holder 51 and the lower magnet holder 52 .

[0056] Specifically, a first magnet 53 is disposed on the upper magnet bracket 51 , a second magnet 54 is disposed on the lower magnet bracket 52 , and the first magnet 53 is disposed opposite to the second magnet 54 . In the specific embodiment shown, the first magnet 53 is arranged on the lower surface...

Embodiment 2

[0065] The brocade thread life test system provided by the present invention can simulate the life test of the actual use scene where the brocade thread is assembled in the speaker and performs high-frequency and rapid swing with the frequency of the speaker input signal, and the life test has high pertinence, accuracy and effectiveness .

[0066] See figure 2 As shown, the brocade thread life testing system includes a frequency sweeper 1 , a power amplifier 2 , a tester 5 , a relay 6 , a timing counter 7 and an ammeter 8 .

[0067] Wherein, the frequency scanner 1 is connected to the power amplifier 2 and can output signals to the power amplifier 2, and the power amplifier 2 can be connected to the relay 6 through a brocade wire and output signals to the relay 6, so The timing counter 7 is connected to the relay 6 and can output a signal to the relay 6, and the relay 6 is connected to the ammeter 8; the tester 5 is the brocade thread life tester described in the first embod...

Embodiment 3

[0075] Brocade thread life test method of the present invention, adopts the brocade thread life test system of the above-mentioned embodiment 2 to test, please refer to image 3 and Figure 4 As shown, the test method includes the following steps:

[0076] S1, place the silk thread to be tested in the adjustment block 9, the adjustment block 9 is placed in the tester 5, and the upper magnet bracket 51 and the lower magnet bracket 52 of the tester 5 are pressed and adjusted mutually Block 9, there is a curved surface in the adjustment block 9, when the adjustment block 9 is compressed, the brocade thread is deformed with the curved surface of the adjustment block 9, and adjusted to form a brocade thread to be measured with a radian;

[0077] Among them, see Figure 5 As shown, the adjustment block 9 includes an upper adjustment block 91 and a lower adjustment block 92 that are molded to each other, and there is a matching arc surface between the upper adjustment block 91 and ...

Abstract

The invention discloses a brocade silk yarn life tester, a brocade silk yarn life testing system and a brocade silk yarn life testing method. According to the brocade silk thread life tester, the brocade silk thread can be effectively prevented from being clamped, it can be guaranteed that swing of the brocade silk thread is highly consistent with swing of an actual use scene, meanwhile, the brocade silk thread can generate Ampere force under the action of a magnetic field to swing when current is input, and thus the life of the brocade silk thread is tested; the magnetic field intensity can be adjusted according to needs so as to adjust the stress of the brocade silk threads. According to the brocade silk yarn service life testing system, the service life measurement of the swing speed, the rotating speed, the radian, the angle, the load, the load current and the like of the brocade silk yarn highly conforming to the actual use scene can be realized, the alternate cycle test under more than two test conditions can be realized, and the service life testing precision of the brocade silk yarn is improved. According to the brocade silk yarn service life testing method, testing is carried out based on the brocade silk yarn service life testing system, traditional motor mechanical driving swing is abandoned, and high-precision testing that the height of the brocade silk yarn accords with the use scene can be achieved.

Description

technical field [0001] The invention relates to the technical field of brocade thread detection, in particular to a brocade thread life tester, a test system and a test method. Background technique [0002] The brocade wire set in the speaker is the wire connecting the voice coil and the terminal, which can lead the current into the voice coil. Because one end of the brocade wire of the speaker is fixed on the fixed speaker terminal, and the other end is fixed on the speaker voice coil that moves at high speed with the input signal, during the working process of the speaker, the brocade wire will swing at high speed following the speaker software, so its swing life is related to Horn life and reliability. Therefore, speaker manufacturers usually need to use tests to evaluate the swing life of brocade wire during production, so as to ensure the quality of the speaker. [0003] At present, the brocade thread swing test is generally carried out with a wire swing tester, and i...
