Abstract

The present invention proposes a woven fabric, a weaving method, and a speaker soft part made of the woven fabric or a fabric formed through weaving with the weaving method. The woven fabric of the present invention includes multiple repeatedly-arrayed large holes and multiple repeatedly-arrayed small holes. Each large hole is provided with six of the small holes arranged around a periphery thereof. The weaving method of the present invention also provides a fabric that includes the previously mentioned large holes and small holes. By means of an elastic structure having the large holes and the small holes formed by yarns, the elasticity and uniformity of the fabric are both enhanced, while porosity is made even higher. Thus, a soft part made of such a fabric, when acted upon by a force, deforms uniformly and shows symmetry of amplitudes in positive and negative directions, and, when compared with the plain-weaving fabric of the prior art, features an enlarged amplitude for the same power and a reduced amount of deformation for long-term high-power operation.

Description

Knitted fabric, weaving method, and speaker software made of the woven fabric or the fabric woven by the weaving method

This creation is about a knitting fabric and a knitting method for knitting fabrics, especially about a knitting fabric and its knitting method for making speaker software.

The various parts in the speaker can be mainly divided into two categories: hardware and software. The hardware is a structure made of non-bendable/deformable materials, such as magnets/U iron/T iron/pot frame/casing, etc. The software is a structure made of elastic materials that can be bent and deformed, such as elastic waves, suspension edges, sound membranes, dust covers, drum paper and so on. Among them, the software is the main component that makes the air vibrate when the speaker sounds, so the performance of the software has a great influence on the quality of the sound quality.

The traditional hit wave, suspension edge, sound film, dust cover, and drum paper are made of flat-woven fabric by thermoforming, so as to make the software of appropriate arc shape. Because the plain weave fabric is inelastic, although the yarn of the plain weave fabric will not be broken by thermoforming, it may have been stretched to a considerable extent, resulting in internal stress concentration or uneven internal stress. In other words, when the software made of plain weave fabric sounds to the speaker, the software stretches unevenly in all directions after being stressed, and cannot be deformed uniformly. As a result, higher nonlinear distortion occurs, which is more pronounced below the lowest resonant frequency point. On the other hand, when the speaker software is made of cloth, it is impregnated with resin and heat-pressed to mold the cloth into a rigid and rigid part. The newly made loudspeaker software vibrates during operation. Because the plain weave material is inelastic, the mature and hardened resin will break due to vibration and bending, resulting in the noise of the new product.

FIG. 7 is a graph showing the relationship between frequency and amplitude obtained by testing a spring wave made of plain woven fabric, and FIG. 8 is a graph showing the relationship between frequency and amplitude obtained by testing a spring wave made from a conventional woven fabric. This test is all data obtained by the German klippel tester. Comparison by graph: relative to the center point, the amplitude difference between forward and reverse directions at the same frequency is not the same. The greater the difference, the greater the distortion. In addition, the larger the amplitude, the better the low frequency performance. It can be seen from Figure 7 and Figure 8 that the measured amplitudes at most frequencies are less than 4mm, and the forward amplitude and reverse amplitude are obviously asymmetrical. The sound produced by such a speaker is seriously distorted, and the sound quality Noticeably bad.

In view of this, it is an urgent problem to be solved in the industry to propose a better improvement solution.

The main purpose of this creation is to propose a weaving method, weaving fabric, and speaker software, which, when applied to a speaker, can enable the speaker to produce a lower distortion rate of sound quality and better low-frequency performance.

In short, in the first movement to the fourth movement, the directional pulling is performed, and the first yarn is pulled to the needle position of one size larger, and the second yarn is pulled to the needle position of one size smaller. Therefore, after the fourth movement is completed, each first yarn is drawn to the needle position of the fourth needle (for example, it is gradually drawn from needle position 0 to needle position 4, or from needle No. 2k to needle position 2k+). No. 4 needle position), and each second yarn is pulled to the needle position of the fourth smaller (such as from the 1st needle position is gradually pulled to the -3 needle position, or from the 2k+1 needle to the needle position Needle positions 2k-3).

Then, in the fifth motion to the eighth motion, reverse pulling is performed, the first yarn is pulled to the needle position of one size smaller, and the second yarn is pulled to the needle position of one larger size. Therefore, after the end of the eighth movement, each first yarn is drawn to the needle position of the fourth smaller needle (for example, it is gradually drawn from the fourth needle position to the zero needle position, or from the 2k+4 needle to the fourth needle position). 2k needle position), and each second yarn is pulled to the fourth needle position (such as from the -3 needle position is gradually pulled to the 1st needle position, or from the 2k-3 needle to the needle position No. 2k+1 needle position), which is equivalent to returning to the starting point.

Between the first movement to the second movement, the second movement to the third movement, the third movement to the fourth movement, the fifth movement to the sixth movement, the sixth movement to the seventh movement , Between the seventh movement and the eighth movement, the way of needle movement is from bottom to top. And between the fourth movement to the fifth movement and the eighth movement to the first movement of the next cycle, the needles are moved on the upper side.

Therefore, the fabric structure woven by the weaving method of this creation is initially as shown in Figure 5, but under the influence of the tension of the yarn, it will reach equilibrium by itself, and the structure shown in Figure 2 will be formed. In this creation, since the fabric and the speaker software formed will have large holes 21 and small holes 22, the fabric or speaker software of this creation will be attached to the large holes 21 and the small holes 22 in a circle shape. And it can maintain elasticity, so that the sound quality of the manufactured speakers is not obvious before and after warming up, and it also greatly shortens the warming-up time and reduces the noise generated by resin breakage.

Figure 6 is a graph showing the relationship between the frequency and the amplitude obtained by testing the elastic waves made of the woven fabric of the present creation. This test is also the data obtained by the German klippel tester. Compared with Fig. 7 and Fig. 8 of the prior art, the elastic waves made by the woven fabric of the present invention have larger amplitudes at the same frequency, and the amplitudes of the forward and reverse directions are also more symmetrical.

Next, please refer to FIG. 6 . Thereby, the woven fabric of the present invention or the fabric made by the knitting method of the present invention can improve the elasticity and uniformity of the fabric through the elastic structure of the large holes 21 and the small holes 22 formed by the yarn, and the porosity is higher. , so it has the advantages of high air permeability and low wind resistance. In addition, the software made of these fabrics deforms uniformly after being stressed, the forward and reverse amplitudes are symmetrical, the amplitude is larger under the same power, and there is no obvious deformation after long-term high-power use. In other words, due to good compliance, the distortion rate is low, resulting in clearer sound quality, fast response, short delay, wide sound range, less noise, low damping, fast heat dissipation, good fatigue resistance, high rigidity, and durability. It has the advantages of large power capability, good dynamic stability, etc., and under high power operation, the quality of the speaker is comprehensively improved.
