Abstract
The present invention relates to a vehicle door, which is installed on the vehicle. The door includes a shutter, a speaker and an inverted tube. The shutter has an accommodation cavity, and the speaker is installed in the shutter. The inverted tube is located in the accommodation cavity, with one end connected with the interior of the vehicle, and the other end forming an acoustic port with a flange. The inverted tube exports the sound from the rear cavity into the car. The inverted tube with the acoustic port can strengthen the resonance effect of the air, and strengthen the sound wave. It can improve the loudness of the speaker, reduce the noise of the airflow, and effectively improve the sound quality of the speaker.
