Problems solved by technology

The drop in sound pressure frequency is not only the deterioration of sound pressure frequency characteristics, but also the corresponding total harmonic distortion (THD), which leads to serious damage to sound quality
If the paper cone is deepened, the peripheral angle of the outer periphery of the paper cone body will become larger, which will not match the existing cone-shaped electric speaker products, resulting in the failure of normal installation and use

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as Figure 6 to Figure 9 As shown, a high-fidelity recycled paper cone includes a paper cone 1 , and a continuous joint line 13 is formed between the outer periphery of the body 11 of the paper cone 1 and the ring 12 . Specifically, the space between the outer peripheral portion 11 of the body of the paper cone 1 and the ring 12 is formed by a curved or straight line with a relatively large outer peripheral angle and a continuous joining line 13 . The joint line 13 can be any one of a curve and a straight line, and if a curve is used, the joint line 13 can be any one of a parabola and an arc.

[0028] such as in Figure 6 Among them, the outer peripheral portion 11 of the carcass is formed by a curve, and the joint line 13 is formed by a curved line, and the outer peripheral portion 11 of the carcass is ...

Abstract

The invention relates to a high-fidelity recycled cone. A continuous combination line of a curve or a straight line with a larger peripheral angle is formed between the peripheral part of the body of the cone and the folding part. After the cone is adopted, the sound pressure frequency characteristic tends to be flat, the total harmonic distortion (THD) cannot be deteriorated, and the sound quality can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a high-fidelity regenerated paper cone. When applied, the paper cone is connected to a cone-shaped electric speaker and installed on a voice coil in a magnetic circuit gap. Background technique [0002] The shape of the paper cone in the existing cone type electric speaker is slender and thin, as attached figure 1 As shown, even a circular speaker may be required to be thinner. If the thickness is thinner than the outer diameter, the section of the paper cone will be as attached figure 2 and image 3 The section shown. [0003] Bond the voice coil installed in the gap of the magnetic circuit to the middle of the paper cone, and perform repeated movements in the front and rear directions according to Fleming's left-hand rule. At this time, because the paper cone is attached figure 2 It is so thin, so the peripheral angle of the outer periphery of the cone body becomes sm...
