Problems solved by technology

When aluminum is used as the speaker shell, especially when the aluminum shell is directly matched with the plastic parts to form a sealed speaker cavity, the vibration phenomenon, that is, noise, is usually generated due to the resonance of the aluminum shell, which makes the sound quality not up to standard. to request

Abstract

The invention provides an anti-resonance metal sound box which includes a metal shell and a plastic part. The metal shell is of a ring wall structure which has openings on both sides and has a hollowinside. The plastic part is used for placing the internal components of the sound box. The metal shell surrounds the plastic part. The plastic part is fixedly connected with the metal shell. There isa sealing mouth at the joint of the plastic part and the metal shell. A sealed cavity is formed inside the metal shell and the plastic part. The resonance frequency points of the aluminum shell are changed and dispersed based on irregular and unequal wall thickness of the aluminum shell, which can eliminate noise and make the sound purer. The internal plastic part is formed through flexible-rigiddouble-color injection molding. The shape of the flexible glue is consistent with the shape of the contact surface of the aluminum shell. After the plastic part is assembled together with the aluminumshell, a sealed cavity is formed, which can prevent leakage. Therefore, good air tightness is ensured, and the sound is clearer.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an anti-resonance metal sound box. Background technique [0002] In order to improve the grade of the product and meet the appearance requirements, audio products usually use metal material aluminum as the outer shell of the product. When aluminum is used as the speaker shell, especially when the aluminum shell is directly matched with the plastic parts to form a sealed speaker cavity, the vibration phenomenon, that is, noise, is usually generated due to the resonance of the aluminum shell, which makes the sound quality not up to standard. to request. Because when the aluminum shell speaker is working, when the frequency point of the sound signal is the same as that of the aluminum shell, the aluminum shell will generate noise due to resonance. Therefore, there is an urgent need on the market for a sound box with an aluminum metal shell that can prevent noise from ...
