Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 2, which are schematic structural views of a horn according to the present invention. The loudspeaker comprises a magnetic conduction piece 10, a magnet 20 arranged on the magnetic conduction piece 10, and a washer 30 arranged on the magnet 20. It is contemplated that the horn may include other functional modules, such as a voice coil assembly, a cone, electrical connections, etc., which are well known to those skilled in the art and will not be described in detail herein.

The magnetic conducting member 10 may be U iron or T iron. The structure and shape of the U-iron or T-iron should be prior art and will not be described in detail here. In this embodiment, the magnetic conducting member 10 is a T-iron. The magnetic conducting member 10 includes a base 11 and a magnetic conductor 12 connected to the base 11. The magnetic conducting member 10 is used for absorbing the magnetism of the magnet 20 and releasing at one end of the magnetic conducting body 12 to form a magnetic field between the voice coil assembly and the washer 30, so that when the voice coil assembly is powered on, the voice coil assembly reciprocates under the action of the magnetic field, and then the voice cone is driven to vibrate, and the purpose of making sound is achieved. It is conceivable that, when the magnetic conductor is U-iron, the magnet 20 and the washer 30 are sequentially accommodated in the U-iron.

The magnet 20 and the washer 30 are respectively sleeved on the magnetizer 12 of the magnetizer 10, and the magnet 20 is clamped between the base 11 and the washer 30. The magnet 20 is annular and is sleeved on the magnetizer 12 to provide magnetic force for the washer 30 and the magnetizer 12.

The washer 30 itself is also a prior art, and includes a through hole 31 penetrating through the magnetizer 12, and a flange 32 disposed on the through hole 31. The extension direction of the flange 32 is perpendicular to the radial direction of the magnet 20. When the voice coil assembly works, the flange 32 and the magnetizer 12 form a magnetic field to drive the voice coil assembly to reciprocate. The washer 30 is typically made of metal, which is typically die cut from a sheet of steel called the "front plate". In order to make full use of the front plate, a plurality of said washers 30 are usually designed on the front plate. The size of the washer 30 will determine its magnetic permeability. In the prior art, the washer 30 is generally circular. Here, only by way of example, on a front plate, a total of 11 circular washers, four horizontal washers and three vertical washers, as shown in fig. 3, may be arranged. The utilization rate of the front plate is 79.1 percent through measurement and calculation. When the washer 30 is configured as a regular hexagon, the length of the maximum diagonal line of the regular hexagon should be the maximum dimension of the washer 30 in the radial direction of the magnet 20, and specifically, the length of the maximum diagonal line of the washer 30 of the regular hexagon should be equivalent to the diameter of a circular washer. At this time, compared with fig. 3, one front plate with substantially the same size, as shown in fig. 4, may be arranged with 13 said washers 30, and through calculation, the utilization rate of the front plate is 89.4%, and the area of the front plate is smaller than that of the front plate when the washers are circular. It is conceivable that, when the washers 30 are regular hexagons, the regular hexagons are arranged in a honeycomb shape. When the washer 30 is a regular quadrangle, the side length of the regular quadrangle is the distance between two opposite sides of the regular hexagon washer. In comparison with fig. 3, for a substantially equally sized front plate, the length of the front plate is 4 times the side length of the square and the width of the front plate is 3 times the width of the square when arranging the washers 30. As shown in fig. 5 and in conjunction with table 1 below, although a front plate was similarly provided with 12 of the washers, the area of the front plate would be minimal and the utilization of the front plate would be 98.8%.

When the regular hexagonal washer is manufactured, the diameters of the through holes 31 of the regular hexagonal washer 30 and the square washer 30 are equal to each other, so as to be sleeved on the magnetizer 12 of the same magnetizer 10. The circumscribed circle of the washer 30 is smaller than the maximum diameter of the magnet, and the through hole 31 of the washer 30 is smaller than the inner diameter of the magnet 20, so as to facilitate the formation of magnetic concentration.

In addition, it is conceivable that the shape of the washer 30 may be set to other shapes, but it is estimated that the washer 30 is a regular hexagon or a square, which is optimal for both the utilization rate of the front plate and the performance. As shown in Table 1, this is a comparative table of the three shapes listed in this example.

TABLE 1 comparison table of various performance parameters of three-shaped washers

In table 1, a circular washer is used as a reference, the length of the maximum diagonal line of the regular hexagonal washer is equal to the diameter of the circular washer, and the side length of the square is equal to the distance between two opposite sides of the regular hexagonal washer.

As can be seen from table 1, for substantially the same substrate area, 13 washers 30 can be punched out of the regular hexagon. Within the allowable range of performance degradation, the weight reduction ratio is the largest. Meanwhile, compared with the T iron corresponding to the circular washer, the weight reduction proportion of the T iron used by the regular hexagonal washer is the largest. The reason why the T-iron is reduced in weight is that when the washer 30 is shaped into a regular hexagon, the base of the T-iron may be also shaped into a regular hexagon. Therefore, the purpose of reducing weight can be achieved relative to a round T-shaped iron base. Therefore, within the allowable range of performance degradation, the regular hexagonal wars is optimal, and the square is inferior.

Compared with the prior art, the horn provided by the invention has the advantages that by designing the shape and the size of the washer 30, the area and the weight of the washer 30 are reduced while the basic performance is ensured, so that the cost of the washer 30 can be reduced, and the cost of the whole horn is further reduced. Meanwhile, each washer is punched and cut from a positive plate, and one positive plate can be fully utilized by adjusting the shape and the size of the washer 30, so that more washers and more waste materials can be obtained, and the cost of each washer 30 is reduced. Specifically, when the washer 30 is designed, the horn may be a regular hexagon or a square. The longest diagonal line of the regular hexagon is the largest dimension of the washer in the radial direction of the magnet. When a square is selected, the size of the regular hexagon should be determined first, and the side length of the square is equal to the distance between two opposite sides of the regular hexagon. Thereby determining the size of the regular hexagon or the square, and further performing typesetting and punching on the front plate.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
