Problems solved by technology

[0007] The above traditional car subwoofers all use 6.5-inch to 12-inch large-diameter woofers, most of which need to be ultra-thin, require special manufacturing, high cost, and difficult to install; Gas, can not form a real subwoofer, and the volume is either too large or too small to meet the volume requirements of the subwoofer; therefore, the bass effect is very poor
However, the precious car body can be used as a subwoofer is very limited, the whole car body must be redesigned, the volume is difficult to meet the requirements, and the sealing process is complicated and difficult
In this way, the existing traditional car subwoofer has the disadvantages of large volume, complex and difficult installation and sealing process in the car, high cost, and poor bass effect.

Embodiment 1

[0070] Such as figure 1 , Figure 10A and Figure 10B As shown, the symmetrically balanced subwoofer box 2 of the present embodiment is cylindrical in shape, and a subwoofer 4 is arranged in the symmetrically balanced subwoofer box 2, and is installed on the front box wall of the symmetrically balanced subwoofer box 2: the subwoofer 4 can be composed of a subwoofer Loudspeaker unit is formed, also can be many, and each subwoofer unit can be circular, also can be elliptic, preferably use conical subwoofer unit, and aperture is 3 inches~4.5 inches; The subwoofer of the present embodiment Speaker 4 is a circular woofer unit with a diameter of 92mm. A bass radiator 5 is also arranged in the symmetrically balanced subwoofer box 2. The bass radiator is also called a passive passive low-frequency radiator or a passive loudspeaker is also called an empty speaker. It has no magnet and voice coil, only a diaphragm and its supporting device; It can be round, oval or rectangular, and i...

Embodiment 2

[0074] Such as figure 2 , Figure 11A and Figure 11B , Figure 16A and 16BAs shown, the difference between the present embodiment and embodiment one is: there are four symmetrically balanced subwoofer boxes 2 in this embodiment, and the woofer 4 of these four symmetrically balanced subwoofer boxes 2 is one, and the bass radiator 5 is two. One, two bass radiators 5 are installed on the box wall of the symmetrical balanced subwoofer box 2 opposite to the woofer 4, and the two bass radiators 5 are symmetrically arranged with the central axis of the woofer 4 as the axis of symmetry. Four symmetrical balanced subwoofer boxes 2 are respectively arranged on the bottom of the front left and right compartment doors 8,9 and the bottom of the rear left and right compartment doors 12,13; Be installed on the mid-treble sound box 6, these 4 mid-treble sound boxes 6 are installed on the top of four compartment doors again, the mid-treble sound box 6 of the present embodiment is a close...

Embodiment 3

[0076] Such as image 3 , Figure 13A and Figure 13B As shown, the difference between the present embodiment and embodiment one is: the symmetrical balanced subwoofer box 2 of the present embodiment is one, the subwoofer 4 in this symmetrically balanced subwoofer box 2 is two subwoofer units, and the subwoofer unit of the bass radiator 5 There are two radiator units, and the two bass radiator units are symmetrically arranged on both sides of the two bass speaker units, and the bass speaker 4 and the bass radiator 5 are both arranged on the same symmetrical balanced bass box 2 wall, Two woofers 4 are φ92mm conical woofers, and two bass radiators 5 are rectangular, with a size of 90mm×125mm. The symmetrical balanced woofer 2 of the present embodiment is arranged in the middle of the rear window platform 14 . All the other are identical with embodiment one.

Abstract

The invention provides a sound system for an automobile, in particular an automotive sound system based on a symmetrical balanced subwoofer, including at least one symmetrical balanced subwoofer and amedium-pitched and high-pitched loudspeaker respectively mounted in the vehicle, one symmetrical balanced subwoofer including at least one bass loudspeaker and at least one bass radiator, the brasslouderspeaker and the brass radiator are respectively arranged on that box wall of a symmetrical balanced subwoofer, and are symmetrically balaned, and the mounting plane of the bass radiator and themounting plane of the brass louderspeaker are coplanar or parallel; at least one medium-pitch and high-pitch loudspeaker is provided, and 1 to 2 loudspeaker units are arranged in each medium-pitch andhigh-pitch loudspeaker. The invention achieves and exceeds the sound quality of the high-end automobile sound system with the cost lower than that the lowest end of the automobile sound system, simplifies the whole automobile production process and reduces the cost through electro-acoustic transducer by the symmetrical balanced subwoofer and the medium-pitched and high-pitched loudspeaker.

Description

technical field [0001] The invention relates to a car audio system, in particular to a car audio system based on a symmetrically balanced subwoofer. Background technique [0002] With the advancement of science and technology, people have higher and higher requirements for the sound quality of car audio; and up to now, the disclosed car audio system solution is the traditional technology subwoofer + mid-high-pitched speaker. 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), and the passive radiation sound box (77 pages) are disclosed. ~78 pages). The car subwoofer box that these disclosed traditional techniques are made has following four kinds of physical structures: [0003] 1. Integrated car subwoofer, that is, the woofer is set on an independent subwoofer body, and the volume of the independent subwoofer body is 20-30 liters to produce ba...
