Description

Bass box assembly structure and automobile comprising same
Technical Field
The utility model relates to the field of automobile accessories, in particular to a bass box assembly structure and an automobile comprising the same.
Background
With the development of economy and the improvement of productivity, automobiles enter more and more families, the requirements of people on the automobiles are no longer only met for walking at present, the popularization of the automobile sound greatly enriches the driving experience of users, and the automobile sound becomes the standard allocation of the automobiles.
The automobile sound equipment is generally provided with a high pitch loudspeaker, a middle pitch loudspeaker and a low pitch loudspeaker, and the three are mutually matched in a closed space of an automobile body, so that the requirement of enjoying beautiful and vivid music in the driving process of a user can be met.
The low-frequency submarine cut-off frequency is higher than that of other types of sound boxes under the same volume, and if lower low-frequency submarine cut-off frequency is to be obtained, a larger box volume is usually required and a loudspeaker unit with a larger caliber is selected; however, the space of the automobile is limited, the space of the automobile door is smaller, functional keys for opening and closing the door, lifting the window and the like are also arranged on the automobile door decorative plate, the storage cavity is also arranged, and the space reserved for the horn is limited, so that the possibility that the bass box can improve the low-frequency diving frequency at the automobile door is limited.
At present, it is a common practice of automobile manufacturers to fix a woofer on a box body with an opening to form a phase inversion type sound box, and place the phase inversion type sound box in a trunk, the phase inversion type sound box has relatively small displacement of a cone basin when a unit works above a resonance frequency Fs, so that the power bearing capacity is high, the resonance distortion is small, but below the resonance frequency, the cone basin displacement is greatly increased, the resonance distortion is increased, under the same volume and unit conditions, the phase inversion type sound box can obtain a lower low-frequency dive cutoff frequency than a closed box, therefore, the existing trunk is provided with more bass boxes which are phase inversion type sound boxes, and more common is a spare tire type bass box which occupies the position of a spare tire in the trunk of an automobile, however, it is known that the spare tire is an important guarantee of the driving process, once a tire of the automobile leaks, the spare tire can be replaced to continue driving, if the spare tire type low sound box is used for replacing the spare tire, once the automobile is anchored and has no spare tire, the spare tire can be replaced immediately, and the travel of a driver is delayed; even if the phase inversion type sound box does not occupy the space of the spare tire, the phase inversion type sound box also occupies other storage spaces of the trunk, and the larger the volume of the box body is, the better the bass diving cut-off frequency is to be obtained.
The driver sacrifices a part of storage space of a trunk in order to obtain high-quality sound experience, or selects a phase-inverted sound box with a small volume in order to keep enough storage space of an automobile trunk, so that pursuit of high-quality sound experience is sacrificed, the driver is difficult to select, how to obtain a bass box of a high-quality sound source with lower low-frequency dive cut-off frequency without occupying a large amount of storage space in the trunk, and the problem expected to be solved by automobile manufacturers is solved.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a bass box assembly structure which is combined with a vehicle body sheet metal part, occupies extremely small trunk space, can realize about 40Hz of submarine cut-off frequency of a bass box under the condition of adopting smaller size of a bass box body in a vehicle body, and reduces the production cost of the bass box by more than 30 percent compared with the traditional spare tire bass box.
The utility model discloses a bass box assembly structure, which comprises a subwoofer, a bass box shell and a vehicle body trunk sheet metal part;
