Description

Technical Field

[0001] The utility model belongs to the technical field of loudspeakers, and in particular relates to a high-strength foamed paper cone for a loudspeaker. Background Art

[0002] The sound basin is an important component of the speaker. It directly affects the speaker's performance indicators such as resonant frequency, effective frequency, sensitivity, distortion, and its sound quality. Traditional sound basin cones are mostly paper cones made of single-layer materials. This single-layer sound basin has the disadvantages of low rigidity, soft material, and inability to withstand high power. When the speaker is used at full load for a long time, it will become loose and deformed, resulting in unsatisfactory damping and sound distortion, affecting the performance of the entire speaker and unable to meet the use requirements of high-power speakers.

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a high-strength foamed paper cone for a speaker.

[0004] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a high-strength foam paper cone for a speaker, comprising a base cone and a surface foam layer, wherein the surface foam layer covers the surface of the base cone, the base cone is made of stainless steel, the base cone comprises an upper support ring and a lower support ring, a plurality of support rods are connected in a circular array between the upper support ring and the lower support ring, a plurality of weight-reducing connection holes are provided on the upper support ring and the lower support ring, the number of the support rods is consistent with the number of the weight-reducing connection holes, and the setting position corresponds to the position of the weight-reducing connection holes in the upper support ring and the lower support ring.

[0005] Preferably, one end of the upper support ring close to the lower support ring is arc-shaped, and the support rod is smoothly connected to one end of the upper support ring close to the lower support ring, and the curvatures of the three are consistent.

[0006] Preferably, the surface foaming layer comprises an inner layer, an outer layer and a middle layer.

[0007] Preferably, the inner layer is applied to the upper surface of the upper support ring, the inner side surface of the support rod and the inner side surface of the lower support ring, the outer layer is applied to the lower surface of the upper support ring, the outer side surface of the support rod and the outer side surface of the lower support ring, and the middle layer is arranged in the weight-reducing connection hole and in the gap between two adjacent support rods to connect the inner layer and the outer layer.

[0008] The utility model has the beneficial effects of setting the sound basin as a double-layer structure, using a base basin made of stainless steel to maintain the overall rigidity of the sound basin, and reducing the overall weight of the base basin by opening weight-reducing connecting holes to avoid affecting the sound quality, and at the same time laying a foaming layer on the surface of the base basin so that the sound basin has the advantages of good rigidity and light specific gravity; the middle layer in the surface foaming layer is embedded in the weight-reducing connecting hole and in the gap between two adjacent support rods to connect the inner layer and the outer layer, which can prevent the speaker from becoming loose and deformed when used at full load for a long time.
