Problems solved by technology

In this way, every process will produce bad defects of stretching on the final product: such as stretch marks, cracks, wrinkles and other bad defects, it is often difficult to obtain products with satisfactory stretching effects for users
Moreover, there are many steps in the above-mentioned technological process, and the operation is complicated.
[0003] Therefore, the realization process of the sound cavity structure still needs to be improved.

Abstract

The invention provides a sound cavity structure and a preparation method and application thereof. The sound cavity structure comprises an upper side face, a left side face and a right side face. The upper side face is used for connecting the left side face and the right side face, the upper side face and the left side face are connected in a smooth-transition mode, and the upper side face and the right side face are connected in a smooth-transition mode. The preparation method of the sound cavity structure comprises the steps that blanking is conducted; blanking is stretched for a first time through a concave-convex mould to obtain a stretched product; and CNC machining is conducted on the stretched product. According to the sound cavity structure prepared through the preparation method, a sound cavity can be formed just through one-time stretching, the stretching process of the sound cavity structure is greatly simplified, the stretching adverse defect generated in multiple stretching is overcome, and the surface quality of the sound cavity structure is increased.

Description

technical field [0001] The present invention relates to a sound cavity structure and its preparation method and application, in particular, to a method for preparing a sound cavity structure, a sound cavity structure and electronic equipment containing the above sound cavity structure. Background technique [0002] At present, the process of realizing the sound cavity structure is usually blanking→stretching (stretching initial shape-initial stretching)→stretching the final product shape (final drawing)-CNC processing, between initial drawing and final drawing Sometimes multiple stretching processes are often added. In this way, every process will produce bad defects of stretching on the final product: such as stretch marks, cracks, wrinkles and other bad defects, it is often difficult to obtain products with satisfactory stretching effects for users. Moreover, the above-mentioned technological process has many steps, and the operation is complicated. [0003] Therefore, t...
