Embodiment Construction
[0042] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some 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] In one embodiment of the present invention, a method for making a composite polymer material audio cabinet is provided, such as figure 1 shown, including:
[0044]Step S101: designing a model, the model includes a backplane and a cabinet;
[0045] Step S102: Complete the mold, apply organic silica gel on the surface of the backplane and the model of the box body, and cure the organic silica gel to form an organic silica gel mold. Open a cleaning hole at the turning point inside the...

Abstract
Disclosed are a mould for a hollow-structured box body of a polymer audio device and an audio device box body manufacturing method using the mould. The mould comprises a fixing outer casing (1) and a silicone mould. The fixing outer casing (1) is detachably provided outside the silicone mould. The silicone mould comprises a mould cavity (21), a mould core (22) and a mould parting plate (23), wherein edges of the mould cavity (21) and edges of the mould core (22) are connected, and the mould parting plate (23) is provided along other edges of the mould cavity (21) and the mould core (22), and when the mould parting plate (23) of the mould cavity (21) and the mould core (22) is closed, the mould core (22) is inside the mould cavity (21), the clearance between the mould core (22) and the mould cavity (21) forms an injection cavity, and a pouring hole is provided on the injection cavity. The method comprises steps such as designing mould species, completing the mould, mixing ingredients, injecting, and vacuum forming. The mould fixes the mould core inside the mould cavity, and the inner cavity of the box body is formed by means of the mould to ensure that the wall of the box body is of a consistent thickness, and the method adds fillers and carbon fibres to resin, improving the density and the toughness of the box body.
Description
technical field [0001] The invention relates to the technical field of audio box production, in particular to a manufacturing method of a composite polymer material audio box and mold equipment used in the manufacturing process. Background technique [0002] In a set of audio products, the role of the speaker box is very important: 1) It can separate the sound radiation before and after the speaker to prevent them from interfering; 2) Damping the resonance of the speaker to reduce the nonlinear distortion of the sound and improve the transient Response; 3) Broaden the low-frequency sound reproduction performance of the speaker, and increase the sensitivity of low-frequency radiation to make the sound more beautiful and pleasant. [0003] A good audio cabinet has a great influence on the choice of materials and craftsmanship for its sound quality and appearance. Resin has been used in audio equipment as a new material, but due to the hardness and brittleness of the resin mat...
