Abstract

A speaker damper manufacturing method comprises: a groove cutting step for expanding a fiber cloth along a first direction, in which the fiber cloth is provided with damper forming areas, and cutting a first groove on the fiber cloth located between two damper forming areas; a forming step for forming a damper shape in the damper forming areas; a cutting step for cutting the damper shape from the fiber cloth to obtain a speaker damper. Thus, in the present invention, when continuously forming the damper shape, the first groove provides a buffer space such that the consecutively formed damper shapes can be prevented from being intertwined with the warp and weft yarns of the first groove, thereby maintaining the position of the subsequent damper forming area to be constant and thus reducing the amount of cloth forming waste and preventing the breakage of warp and weft yarns.

Description

Method for manufacturing horn bounce

The invention relates to a method for manufacturing a horn elastic wave.

The structure of the horn includes permanent magnets, voice coils, elastic waves, diaphragms, and the like. Each component is related to the sound quality of the speaker. The manufacturing method of the conventional horn elastic wave first passes a fiber cloth body through the impregnating resin, and then dries the fiber cloth body; then, in the forming step, the fiber cloth body is first spread flattened, and then a plurality of fiber cloth bodies are formed. In the elastic wave forming region, the distance between the elastic wave forming regions is equal, and then a plurality of elastic wave forming regions on the fiber cloth body are sequentially crimped to form a plurality of elastic wave shapes; finally, the cutting step is performed, and the cutting step is utilized. A cutting device sequentially cuts each elastic wave shape from the fiber cloth body to obtain a plurality of elastic waves, and the elastic waves have a disk shape and a wavy cross section.

However, the conventional method of manufacturing the horn elastic wave is automated and continuously performed, and the fiber cloth body has elasticity, and each of the subsequent elastic wave forming regions is formed when each elastic wave shape is collapsed from the flat elastic wave forming region. The position is pulled forward by a distance by the shrinking force of the previous elastic wave forming region which is collapsed into an elastic wave shape. As a result, the forming mold will not be accurately aligned in each of the subsequent elastic wave forming regions. The pitch of each of the elastic wave shapes formed later will be made larger than the preset. Since the fabric between each of the elastic wave shapes will form a waste, the above problem will result in more waste than originally thought, which is quite wasteful.

According to the above, when the two elastic wave shapes are sequentially shrunk from the flat elastic wave forming region, the warp and weft yarns between the two elastic wave shapes are simultaneously pulled by the two elastic wave-shaped two-stretching force. The fracture further causes the fiber cloth to be torn.

Further, when the elastic wave shape is formed by shrinking the elastic wave forming region, the elastic wave shape has an outer ring portion and an inner ring portion, and the inner ring portion surrounds a cutout region. In the cutting step of the conventional horn blast wave, the cutting device is provided with two knives, one of which cuts the shape of the elastic wave along the outer ring shape of the elastic wave shape, and the other one will The cut-away region of the wave shape is cut along the inner ring portion. Only the cutting device must have two tools to cut the shape of the elastic wave, which is costly and inefficient.

The main object of the present invention is to provide a method for manufacturing a horn elastic wave, which is to cut a first dicing groove between each elastic wave forming region, so that each elastic wave forming region does not affect subsequent elastic waves after the forming step. The position of the forming area, and the fiber cloth body will not be torn.

A secondary object of the present invention is to provide a method for manufacturing a horn elastic wave. In the forming step, a circular hole is directly formed in the inner ring portion of the elastic wave shape, thereby improving the manufacturing efficiency of the horn elastic wave and saving cost.
