Embodiment 1

[0050] Such as Figure 1A , Figure 1B As shown, the present embodiment is that an "h" shaped car door subwoofer is directly replaced with an existing 6.5-inch subwoofer in the front right car door of the former car. The front box body 2 of the car door subwoofer of the present embodiment is a cylindrical box body, and the rear box wall extends outwards to form a cylindrical installation hole along 8, and the outer diameter of the installation hole along 8 will be smaller than the original car subwoofer installation. The hole diameter of the steel plate is about 145mm. Here the diameter and height of the front box body 2 will satisfy not to interfere with the trim panel in the compartment door. The diameter of the front box body 2 of the present embodiment is φ165mm, and the diameter of the mounting hole along 8 is φ130mm. Active subwoofer 5 is arranged on the front box wall of front cabinet 2, and active subwoofer 5 can be circular also can be oval, and what present embodim...

Embodiment 2

[0055] Such as Figure 2A , Figure 2B As shown, the difference between the present embodiment and the first embodiment is: a pair of passive woofers 6 of the present embodiment, one of which is installed on the rear box wall of the rear box body 3, and the other is installed on the front box body 2 On the front box wall, and coplanar with the installation plane of the active woofer 5. Therefore, the inner diameter of the end where the crutch throat pipe 4 of the present embodiment communicates with the front box body 2 is greater than that of embodiment one; furthermore, the shaft of the other end where the crutch throat pipe 4 of the present embodiment communicates with the rear box body 3 The cross-section is an inwardly concave arc surface. The rest are all the same as in Example 1.

Embodiment 3

[0057] Such as Figure 3A , Figure 3B As shown, the difference between the present embodiment and the first embodiment is: a pair of passive woofers 6 of the present embodiment, one of which is installed on the front wall of the rear box 3, and the other is installed on the front wall of the front box 2. On the front box wall, and coplanar with the installation plane of the active woofer 5. The rest are all the same as in Example 1.

Abstract

The invention relates to an automobile sound system, in particular to an automobile door subwoofer, which is characterized in that a front box body and a rear box body are independent sealed box bodies, the front box body is communicated with the rear box body through a crank throat pipe to realize the conduction of sound airflow, and the communicated part of the crank throat pipe and the front box body and the communicated part of the crank throat pipe and the rear box body are inclined; the front box wall of the front box body is provided with an active woofer. A passive woofer is accommodated in the rear box body; one passive woofer is arranged or arranged in pairs; when one passive woofer is arranged, the passive woofer is installed on the front box wall or the rear box wall of the rear box body, when the passive woofer is arranged in pairs, the passive woofer corresponds to the passive woofer front and back, one passive woofer in each pair is installed on the box wall of the rearbox body, and the other passive woofer in each pair is installed on the box wall of the rear box body or the box wall of the front box body. According to the invention, the volume of the subwoofer isgreatly reduced, and the original 6.5-inch bass loudspeaker of the automobile door can be easily and directly replaced under the condition that the original automobile door structure is not changed.

Description

technical field [0001] The invention relates to a car audio system, in particular to a car door subwoofer. Background technique [0002] With the development of automotive electronics technology and the maturity of AI (artificial intelligence), people have higher and higher requirements for the sound quality of car audio and lower and lower cost requirements. At present, the car bass made by the prior art has the following four structures: [0003] 1. Four-door woofer, that is, four 6.5-inch woofers are respectively installed in the lower part of the four compartment doors, and the volume formed by the outer wall steel plate and inner wall of the door is used as the subwoofer body; the disadvantage is that the air leakage cannot form the subwoofer body , At best, it can only be an acoustic baffle, the bass sound quality is poor, and the cost is high. [0004] 2. Integrated car subwoofer, one or two 4-inch to 12-inch woofers are set on a 20-40-liter box made of plastic or w...
