Problems solved by technology
Speakers in the related art usually use injection molded shells. Due to the limitation of material properties, the speaker products with plastic shells have poor heat dissipation effect.
However, during the processing of the metal shell, the material is usually stretched, which causes the structure of the metal shell to be limited and affects the design of the metal shell structure.

Embodiment Construction
[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0043] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the figure). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0044] At the same time, the meaning of...

The invention discloses a shell processing method, a shell structure and a loudspeaker monomer. The shell processing method comprises the following steps: providing a strip-shaped plate made of a magnetic conductive metal material; cutting the strip-shaped plate through a punching technology, obtaining a strip-shaped body part and a plurality of magnetic conductive plates formed on the strip-shaped body part, and forming a notch between every two adjacent magnetic conductive plates; bending the strip-shaped body part into a closed-loop structure through a bending process, so that the two endsof the strip-shaped body part are matched to form a connector, and the closed-loop structure is provided with a containing cavity; bending the plurality of concentrating flux plates towards the interior of the accommodating cavity by adopting a side pushing process; and connecting and sealing the interface by adopting a welding process or a riveting process to obtain the shell structure. Accordingto the machining method of the shell, stretching treatment is not needed, the manufacturing process is greatly simplified, shell structures can be easily produced on a large scale, and the machiningprecision is improved.
Description
technical field [0001] The invention relates to the technical field of acoustic and electric products, in particular to a processing method for a casing, a casing structure prepared by using the processing method, and a loudspeaker unit using the casing structure. Background technique [0002] The loudspeaker is an important acoustic component of portable electronic equipment. It is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. With the development of miniaturization of electronic devices such as mobile phones, correspondingly, the size design of speakers is becoming more and more challenging. In the related art, the speaker usually adopts an injection-molded shell, and due to the limitation of material properties, the speaker product with a plastic shell has a poor heat dissipation effect. However, during the processing of the metal shell, the material usually needs to be stretched, which results in the li...
