[0025] The present utility model will now be described in further detail with reference to the drawings. These drawings are all simplified schematic views, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0026] Please refer to Figure 2 , Figure 2 is a schematic structural view of the optimal embodiment of the fabric of the present utility model. As Figure 2As shown, at least one embodiment provides a fabric formed in one piece, including: a plastic part covering portion 6 and a sound transmission area covering portion 7. The plastic part covering portion 6 and the sound transmission area covering portion 7 are integrally woven, avoiding cutting after the fabric is formed, greatly saving raw materials, reducing environmental pollution, saving the cutting process, and saving the subsequent processing cost of the finished product. In addition, the plastic part covering portion 6 and the sound transmission area covering portion 7 respectively correspond to the plastic part and the holes, meeting the requirements of shell protection and good sound transmission at the same time; the plastic part covering portion 6 and the sound transmission area covering portion 7 include a double-thread structure, and the sound transmission area covering portion 7 includes an air layer belt and an alternating front and back rocking bed purl structure, and the air layer belt and the alternating front and back rocking bed purl structure are arranged at intervals. The raw material knitting thread of the fabric is a 167dt / 36f×3 low-elastic polyester colored yarn.

[0027] The following specifically describes the production mechanism process of the fabric:

[0028] I. Weaving process:

[0029] The weaving raw material uses a 167dt / 36f×3 low-elastic polyester colored yarn. The double-rib structure is adopted for the parts without sound transmission requirements (such as Figure 4 ), and the air layer belt and alternating front and back rocking bed purl structure is adopted for the parts with sound transmission requirements (such as Figure 5 ).

[0030] The E8.2 computerized flat knitting machine is used in the weaving process. The needle pitch is small, making the fabric quality more delicate. The polyester yarn uses the stock solution colored yarn, which does not require subsequent dyeing, the process is more environmentally friendly, and the color fastness is better.

[0031] The specific steps of calculating the knitted pattern diagram through the horizontal and vertical densities for the one-piece forming knitting sound box cover method include: using the determined yarn and structure to first conduct a small sample test knitting on the computerized flat knitting machine to determine the parameters required for knitting (in the optimal implementation example, the suitable coil length for knitting is 10.5, the pulling is 1.8 for every 100 needles, and the knitting speed is 0.75); ironing and shaping the small sample; measuring the horizontal and vertical densities of the shaped small sample; multiplying the horizontal size of the sound box sample by the weft density and multiplying the vertical size of the sound box sample by the warp density to obtain the final required horizontal and vertical coil numbers corresponding to the sound box model. According to the calculated required coil numbers for the corresponding knitted pattern, input the model data into the knitting design software to create the required knitted model for knitting. For the part that needs to decrease stitches, only one stitch can be decreased in one row, and for adding stitches, only one stitch can be added in one row. According to the modified knitted model, set the corresponding knitting parameters, and then knit the required shape on the machine.

[0032] II. Making the knitting program for the machine:

[0033] (1) Input the drawn knitted model pattern program into the new pattern project of the software, and a corresponding coil knitting simulation diagram can be generated according to the shape of the model;

[0034] (2) Set the corresponding coil length, drawing, knitting speed and other parameters according to the parameters obtained from the trial knitting of the sample.

[0035] (2) Export the machine program file and knit on the machine.

[0036] In summary, the process directly weaves the required shape of the audio cover by calculating the horizontal and vertical densities, generates a knitting program, and weaves on the machine, saving the cutting link, having high production efficiency and good quality, and avoiding the problem of edge fraying after cutting the knitted fabric. Different flower patterns and structures can be woven on a single piece of fabric according to different usage requirements, improving the scope of use of the fabric.

[0037] The present utility model also provides an automotive audio, including a housing, and a fabric formed in one piece as described above is wrapped on the housing. The housing includes a plastic part 1 and a sound transmission hole 2 opened on the plastic part 1. Specifically, a plastic part covering portion 6 is provided on the plastic part 1, and a sound transmission area is provided at the position of the sound transmission hole 2. In order to avoid edge fraying of the fabric and enhance the adhesion firmness between the fabric and the housing surface, in addition to adhesive bonding, the effect of squeezing the fabric between two housings is also designed. Specifically, an extension piece 61 is provided at the outer edge of the plastic part covering portion 6. The plastic part covering portion 6 is consistent with the outer contour of the housing. The extension piece 61 is an extra part at the edge, used to wrap the side of the housing. In addition, an assembly strip 3 is provided at the edge position of the outer contour of the plastic part 1, and a long groove 4 is provided on the assembly strip 3. A rubber strip 5 is embedded in the long groove 4. One side of the rubber strip 5 is provided with a serrated groove 51. The extension piece 61 is arranged in the abutting surface of the rubber strip 5 between two adjacent housings. After the housing is assembled on the audio skeleton, the edges of the two housings need to be aligned and abutted. At this time, the serrated grooves 51 at the position of the rubber strip 5 are abutted in a staggered manner, so that the extension piece 61 is folded inside to avoid edge fraying.

[0038] In summary, by setting a fabric formed in one piece, the corresponding shape can be directly knitted according to the automotive plastic part model, avoiding the cutting of the fabric after forming, greatly saving raw materials, reducing environmental pollution, saving the cutting process, and saving the post-processing of the finished product; by setting a double-thread structure, an air layer belt and a one-over-one front and back rocking bed purl structure, different knitting method structures are corresponding to different areas of the audio housing, meeting the requirements of both housing protection and good sound transmission at the same time; by setting a rubber strip 5 with a serrated groove 51, the connection tightness between the fabric edge and the housing is enhanced, avoiding edge fraying.
