Utility model content

For solving the problem, the utility model discloses a kind of all-in-one-piece loudspeaker net cover structure and automobile, achieving meeting loud speaker on the basis that requires of Penetration ration proposed, adding the intensity of loudspeaker mask.

According to an aspect of the present utility model, provide a kind of all-in-one-piece loudspeaker net cover structure, comprising: guard body; Be positioned at the die joint in the centre position of guard body; Be positioned at the first surface of die joint both sides and second, first surface is the outer surface of guard body, and second is the inner surface of guard body; Be provided with some reinforcements on the first face; First surface offers through multiple first perforations to die joint, and the first perforation is one trapezoidal along the cross sectional shape of the axis direction in hole, and trapezoidal upper base is positioned at the side of die joint; Second face offers through multiple second perforations to die joint, and the second perforation is one trapezoidal along the cross sectional shape of the axis direction in hole; Trapezoidal upper base is positioned at the opposite side of die joint; First perforation and the second perforation one_to_one corresponding, the first perforation and second perforation corresponding with this first perforation are communicated with and have identical axis.

Alternatively, the draft angle of described first surface is 6-8 °, and the draft angle of described second is 12-20 °.

Alternatively, the thickness of described loudspeaker gauze is 2.5 ~ 3.0mm.

Alternatively, described reinforcement height is 4 ~ 5mm.

Alternatively, described reinforcement width is 0.6 ~ 1.0mm.

Alternatively, described reinforcement adopts concentric circles arrangement.

Alternatively, described reinforcement adopts the arrangement of regular hexagon form.

According to another aspect of the present utility model, additionally provide a kind of automobile, comprise above-described loudspeaker net cover structure.

The beneficial effects of the utility model are:

In embodiment of the present utility model, by the change to die joint position and draft angle, meet the requirement of loud speaker to guard Penetration ration better, meanwhile, add quantity and the intensity of reinforcement, improve the intensity of loudspeaker gauze entirety.

Embodiment

For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

As shown in figs. 2 to 4, loudspeaker gauze in embodiment of the present utility model, loudspeaker gauze comprises: guard body; Be positioned at the die joint 4 in the centre position of guard body; Be positioned at first surface A and second B of described die joint 4 both sides, described first surface A is the outer surface of described guard body, and described second B is the inner surface of described guard body; Described first surface A is provided with some reinforcements; It is one trapezoidal that first surface A offers through multiple first perforation 2, first perforations 2 to described die joint along the cross sectional shape of the axis direction in hole, and described trapezoidal upper base is positioned at the side of die joint 4; It is one trapezoidal that second B offers through multiple second perforation 3, second perforations 3 to described die joint along the cross sectional shape of the axis direction in hole; Described trapezoidal upper base is positioned at the opposite side of described die joint 4; First perforation 2 and the second perforation 3 one_to_one corresponding, the first perforation 2 and second perforation 3 corresponding with this first perforation 2 are communicated with and have identical axis.It is less that perforation on loudspeaker gauze can do, and permeability is better, and reduce mold members number of spare parts, it is more convenient to install simultaneously.

Alternatively, as shown in Fig. 3 ~ Fig. 4, the draft angle of described first surface A is 6-8 °, and the draft angle of described second B is 12-20 °, changes the permeability of perforation, makes it better meet the requirement of loud speaker to the Penetration ration proposed.

Alternatively, as shown in Figure 3, the thickness of described loudspeaker gauze is 2.5 ~ 3.0mm, and cost-saving, outward appearance is good.

Alternatively, as shown in Figure 4, described reinforcement 1 is highly 4 ~ 5mm, and reinforcement intensity is larger.

Alternatively, as shown in Figure 4, described reinforcement 1 width is 0.6 ~ 1.0mm, effectively enhances the intensity of guard body.

Alternatively, as shown in Figure 5, when guard surface is circular, reinforcement 1 adopts concentric circles to arrange, and saves the space shared by reinforcement 1, better meets the permeability of guard.

Alternatively, as shown in Figure 6, when mask exterior is characterized as irregularly shaped, described reinforcement 1 adopts regular hexagon form to arrange, and adopts this kind of arrangement mode, increases the permeability of guard.

According to another aspect of the present utility model, additionally provide a kind of automobile, comprise the loudspeaker gauze in above-described embodiment, install the automobile of this loudspeaker gauze, acoustics obviously improves, and the intensity of loudspeaker gauze self there has also been obvious raising simultaneously.

The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
