The elastic wave and the cone are assembled in sequence from bottom to top and are positioned in the basin frame of the upper shell. The mesh enclosure is installed above the upper shell. The magnetic circuit, the basin frame of the upper shell, the elastic wave, the cone and the net cover are all arranged concentrically. The upper shell and the basin stand are of an integrated structure. The cone body of the cone presents a plane shape. The utility model adopts the integrated design of combining the upper shell and the basin frame, and can reduce the thickness of the sound box by 5 mm. The cone body of the cone is plane. The planar body reduces the thickness of the sound box by 1cm. Thus achieving the thinnest effect. And because the shell is made of aluminum alloy, the heat dissipation of the loudspeaker box can be facilitated.

Description

Ultra-thin on-vehicle subwoofer audio amplifier

Technical Field

The utility model relates to a vehicle-mounted sound box, in particular to an ultrathin vehicle-mounted bass loudspeaker box, and belongs to the field of sound equipment.

Background

At present, with the continuous upgrade of the automobile industry, people have an increasing demand for automobiles, an increasing automobile ownership rate, and an increasing driving time, and an increasing demand for driving entertainment, and pursuing an automobile sound with a multimedia function is started. In order to improve the sound quality, the cone body of the loudspeaker of the sound box is larger and deeper, which is one of reasons why the volume of the sound box is larger and larger.

Since the interior space of the car is not large, and as small-sized vehicles are popular, conventional audio devices face the defect that the volume of the devices is too large, and the installation in the car is inconvenient.

Disclosure of Invention

In order to overcome the problems, the utility model provides an ultrathin vehicle-mounted bass loudspeaker box.

In order to achieve the above purpose, the utility model adopts the following technical scheme: an ultra-thin vehicle-mounted subwoofer sound box comprises a shell, a sound circuit board, a control panel, a magnetic circuit, a damper, a cone and a net cover. The shell is formed by connecting an upper shell and a lower shell. The sound circuit board, the control panel and the magnetic circuit are respectively positioned in the lower shell. The elastic wave and the cone are assembled in sequence from bottom to top and are positioned in the basin frame of the upper shell. The mesh enclosure is installed above the upper shell. The magnetic circuit, the basin frame of the upper shell, the elastic wave, the cone and the net cover are all arranged concentrically. The upper shell and the basin stand are of an integrated structure. The cone body of the cone presents a plane shape.

Preferably, the upper shell and the lower shell are made of aluminum alloy.

Preferably, a dust cover is arranged above the cone.

Preferably, the sound circuit board is mounted on the right side of the bottom of the lower shell.

Preferably, the magnetic circuit is mounted at the bottom center of the lower housing.

Preferably, the control panel is nested in the left side wall of the lower shell.

Preferably, the cone and the elastic wave are concentrically arranged at the center of the cone frame.

The utility model adopts the integrated design of combining the upper shell and the basin frame, and can reduce the thickness of the sound box by 5 mm. The cone body of the cone is plane. The planar body reduces the thickness of the sound box by 1cm. Thus achieving the thinnest effect. And because the shell is made of aluminum alloy, the heat dissipation of the loudspeaker box can be facilitated.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments that may be obtained by a person of ordinary skill in the art without making any inventive effort fall within the scope of the present utility model.

As shown in fig. 1-2: an ultrathin vehicle-mounted subwoofer loudspeaker box comprises a shell, a sound circuit board 9, a control panel 7, a magnetic circuit 6, a damper 4, a cone 3 and a net cover 1. The housing is formed by connecting an upper housing 5 and a lower housing 8. The sound circuit board 9, the control panel 7 and the magnetic circuit 6 are respectively arranged in the lower shell 8, the sound circuit board 9 is arranged on the right side of the bottom of the lower shell 8, the magnetic circuit 6 is arranged at the center of the bottom of the lower shell 8, and the control panel 7 is nested and arranged in the left side wall of the lower shell 8. The elastic wave 4 and the cone 3 are assembled in sequence from bottom to top and then are arranged in the center of the basin frame of the upper shell 5. The mesh enclosure is mounted above the upper housing 5. The magnetic circuit 6, the basin frame 11 of the upper shell 5, the elastic wave 4, the cone 3 and the net cover 1 are all arranged concentrically. The upper shell 5 and the basin frame 11 are of an integrated structure. The cone body 10 of the cone 3 is not conical but planar. The upper shell 5 and the lower shell 8 are made of aluminum alloy. A dust cover 2 is arranged above the cone 3.

After the equipment is electrified and opened, the voice coil is driven by the magnetic field to vibrate so as to drive the cone body 10 of the cone 3 to start vibrating, and the received signals are converted into various sounds.

As shown in fig. 3-4: the cone body 10 of the cone 3 has a plane structure, which is different from the cone body 10 of the traditional cone shape, and the cone shape design is cancelled, so that the cone body 10 and the rubber edge form a plane parallel. Because the device is a bass loudspeaker box, the change can reduce the loudness of sound but does not influence the shocking feeling brought by the heavy bass output by the loudspeaker box to people and does not influence the music experience of a user. Thus sacrificing a portion of the sound quality to raise the carcass 10 to a reduced thickness of only 58cm.

Unless specifically stated otherwise, in the present utility model, if the terms "left", "right", "upper", "top", "middle", "concentric", etc. indicate orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of description, but it is not indicated or implied that the means or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, so that the terms describing the orientation or positional relationship in the present utility model are used for illustration only and are not to be construed as limitations of the present patent, and it is possible for those skilled in the art to understand the specific meaning of the terms described above in conjunction with the drawings and according to circumstances.
