Embodiment 1

[0059] Such as Figure 1A , Figure 1B As shown, the subwoofer of the present embodiment has only a single-cavity subwoofer housing 1, which is in the shape of a cuboid, and four subwoofer speakers 2 are arranged in the subwoofer housing 1, and they are in groups of two. They are respectively symmetrically installed on the front box wall of the subwoofer body 1; the subwoofer 2 may consist of one or more subwoofer units, and each subwoofer unit may be circular or elliptical. In this embodiment, a circular woofer unit with a diameter of 92 mm is installed in each woofer 2 . Two groups of bass radiator groups 3 are also arranged in the subwoofer body 1, and each group of bass radiators 3 is composed of a pair of (2) bass radiator units, and a pair of bass radiator units in each group are arranged correspondingly before and after each other. . Bass radiators are also known as passive low-frequency radiators, also known as empty speakers, which have no magnets and voice coils, o...

Embodiment 2

[0064] Such as Figure 2A , Figure 2B As shown, the difference between this embodiment and Embodiment 1 is: there are two woofers 2 in this embodiment, and the bass radiator group 3 is two groups of four bass radiator units, and these bass radiator units are the same Round bass radiator unit. The rest are all the same as in Example 1.

Embodiment 3

[0066] Such as Figure 3A , Figure 3B As shown, the difference between the present embodiment and the second embodiment is that there is one woofer 2 in this embodiment, and the bass radiator group 3 is a group of two bass radiator units. All the other are identical with embodiment two.

Abstract

The invention relates to a single-cavity sandwich-type automobile subwoofer. The subwoofer comprises a bass box body, woofers and bass radiator groups, wherein the woofers and the bass radiator groupsare installed in the bass box body. There is at least one woofer and the woofer is installed on the box wall of the bass box body. There is at least one bass radiator group and each group comprises two bass radiator units. The two bass radiator units are arranged correspondingly in front and back portions and are installed on the box wall of the bass box body. The installation plane of the two bass radiator units is coplanar, parallel, vertical or tilted to the installation plane of the woofer. In the invention, through the interaction of the woofer and the bass radiator group, electroacoustic conversion is completed in a single bass box body so that the size of the subwoofer is reduced by 90%; and the weight is light, the shocking, heavy, elastic and pure bass can be generated so that problems that the subwoofer is large and is not easy to install are solved. The subwoofer of the invention is suitable for internal installation of front installation, rear installation and the like ofan automobile, wherein the internal installation has requirements of the small size, thin installation and good bass.

Description

technical field [0001] The invention relates to a sound box of an automobile sound system, in particular to a single cavity sandwich type automobile subwoofer. Background technique [0002] With the advancement of science and technology, people have higher and higher requirements for the sound quality of car audio. In the "Speaker and Sound Box Design Manual" published by Fujian Science and Technology Press in July 2008, the closed sound box (60-67 pages), the open-type sound box (67-77 pages), the passive radiation sound box (77 pages) are disclosed. ~78 pages). The car subwoofers made by these public technologies have the following four structures: [0003] 1. An integrated car subwoofer, that is, the woofer is set on the subwoofer body, and the 20-30 liter box volume of the subwoofer body is used to produce bass. [0004] 2. Car body type car subwoofer, that is, the woofer is installed on a box in a certain space formed by the car body, and the body is used to form 20 ...
