Abstract

The invention relates to an A-column decoration plate with a loudspeaker sealing structure and a system, and relates to the technical field of automobile parts. A loudspeaker in the A-column system is provided with a first sealing assembly, the A-column decoration plate is provided with a sealing structure, the inner side face of the A-column decoration plate is provided with a second sealing assembly and a reinforcing assembly, and the first sealing assembly is used for guiding the second sealing assembly to be buckled to a loudspeaking opening so as to jointly seal the second sealing assembly and sealing foam to form a sound receiving cavity. The reinforcing assembly is used for dividing a corresponding area of the sound receiving cavity to form a first sealing area and a second sealing area, and enabling a part of sound waves emitted by the loudspeaker to be reflected in the first sealing area and then to be output through the second sealing area so as to improve the sound effect. According to the A-column system provided by the invention, the sealing structure is arranged on the A-column decoration plate, so that rapid alignment and buckling between the A-column decoration plate and the loudspeaker can be ensured, the buckling condition can be checked and confirmed to ensure the sealing performance, in addition, the sound intensity of the loudspeaker can be improved as much as possible, and the sound effect can be ensured.

Description

technical field [0001] The application relates to the technical field of auto parts, in particular to an A-pillar trim with a loudspeaker sealing structure and a system thereof. Background technique [0002] At present, with the development of the automobile industry, more and more electronic devices are applied to automobiles, and the quality of audio entertainment functions occupies a large proportion in the evaluation of consumers' rest and experience satisfaction. Therefore, more and more car models Both will be equipped with tweeters and woofers. Usually, the woofer will be installed and fixed on the body sheet metal or sheet metal bracket because of its wide audio range, high frequency of use, large volume and high weight of the woofer; Will be installed directly on the interior trim. Regardless of the woofer or the tweeter, in order to ensure the sound effect of the woofer, an effective sealing structure is very much needed. [0003] In the related art, the sealing...
