[0002] In today's modern life, in order to enrich their daily entertainment life, people generally use speakers to play music to relax. Speakers are common working parts of speakers. Speakers are transducers that can convert electrical signals into sound signals. Specifically, they rely on the vibration of the speaker's voice coil, which in turn drives the vibration of the paper cone to make sound. The paper cone currently used in speakers is usually assembled from a variety of parts to form a cone-shaped structure, but this will increase the specifications and dimensions, which is not conducive to the development of the paper cone towards lightness and thinness, resulting in poor structural strength. Long-term use will easily cause aging and deformation of the structure, shortening its service life. Utility Model Content

[0020] The utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, a flat thin speaker cone of the utility model comprises a drum paper 1 and a hanging edge 2 arranged on the drum paper 1, wherein the hanging edge 2 is arranged around the circumference of the drum paper 1, and the hanging edge 2 comprises an inner ring 21 connected to the drum paper 1, an outer ring 22 arranged concentrically with the inner ring 21, and a connecting ring 23 arranged between the inner ring 21 and the outer ring 22, wherein the connecting ring 23 is in a smooth transition arc shape, and the inner ring 21, the connecting ring 23, and the outer ring 22 are integrally formed, and the drum paper 1 is provided with a side close to the hanging edge 2. A plastic sheet 11 and a moisture-proof paper 12 connected to the plastic sheet 11 are provided. The moisture-proof paper 12, the plastic sheet 11 and the drum paper 1 are stacked and bonded in sequence. A first adhesive layer 13 is provided between the moisture-proof paper 12 and the plastic sheet 11. The lower surface of the moisture-proof paper 12 is bonded to the upper surface of the plastic sheet 11 through the first adhesive layer 13. A second adhesive layer 14 is provided between the plastic sheet 11 and the drum paper 1. The lower surface of the plastic sheet 11 is bonded to the upper surface of the drum paper 1 through the second adhesive layer 14.

[0022] The hanging edge 2 includes an integrally formed inner ring member 21, a connecting ring 23, and an outer ring member 22. The connecting ring 23 is connected between the inner ring member 21 and the outer ring member 22. While ensuring that the inner ring member 21 and the outer ring member 22 are concentrically arranged, the connecting ring 23 can better fix the position between the inner ring member 21 and the outer ring member 22, so that the overall structure of the hanging edge 2 is compact, which is convenient for manufacturing and molding, and meets the design requirements of lightness and thinness. The drum paper 1 is stacked and laminated with a moisture-proof paper 12 and a plastic sheet 11 in a planar structure. The lower surface of the moisture-proof paper 12 is laminated with the upper surface of the plastic sheet 11 through the first adhesive layer 13, and the lower surface of the plastic sheet 11 is then laminated with the first adhesive layer 13. The second adhesive layer 14 is bonded to the upper surface of the drum paper 1, and then fixed by a pressing method. The plastic sheet 11 can improve the structural strength and bending resistance of the drum paper 1. The moisture-proof paper 12 is bonded to the surface of the plastic sheet 11. The moisture-proof paper 12 is a prior art. It is made by coating asphalt between two layers of base paper. It has good moisture-proof performance and can play a role in moisture-proof protection for the plastic sheet 11 and the drum paper 1. Since the moisture-proof paper 12, the plastic sheet 11, and the drum paper 1 are all planar structures, and the combination and layout of the three are reasonable, the thickness is thin and the appearance is beautiful, thereby improving the overall structural strength and moisture-proof performance of the speaker paper cone. The utility model has a compact structure and a reasonable design, meets the requirements of lightweight design, improves structural strength, and prolongs service life.

[0023] The connecting ring 23 of this embodiment is provided with arc ribs 24 on both sides. The arc ribs 24 are formed by protruding from the outer wall of the connecting ring 23 and connected between the inner ring 21 and the outer ring 22. The connecting ring 23 includes a straight segment 231 and an arc segment 232 integrally formed with the straight segment 231. The arc ribs 24 are provided in plurality and are arranged at intervals along the arc segments 232. Specifically, the connecting ring 23 includes two straight segments 231 and two arc segments 232. One straight segment 231, one arc segment 232, another straight segment 231, and another arc segment 232 are connected end to end in sequence to form a ring structure. Multiple arc ribs 24 are arranged at intervals along the two arc segments 232. Each arc rib 24 is located between the inner ring 21 and the outer ring 22, thereby enhancing the structural strength and rigidity of the suspension 2, avoiding bending and deformation caused by vibration during long-term use, and ensuring stable and durable performance of the suspension 2.

[0024] A matching groove 25 is provided between the connecting ring 23 and the outer ring member 22 of this embodiment, and the matching groove 25 is used to separate the connection between the connecting ring 23 and the outer ring member 22. Specifically, since the existing speaker paper cone and the basin frame are generally bonded and fixed by glue, but the glue is easy to loosen and fall off due to weak bonding during long-term use, it is particularly important to fix the position of the speaker paper cone. The matching groove 25 is used to separate the connection between the connecting ring 23 and the outer ring member 22 and is recessed downward. The speaker paper cone is placed at the port of the basin frame. The speaker paper cone is connected to the hard frame at the edge of the basin frame through the matching groove 25, so that the inner groove wall of the matching groove 25 is tightly against the outer wall of the frame, and the position of the speaker paper cone on the basin frame is effectively fixed, so that screw-free installation and fixation are achieved, and the operation is simple and convenient.

[0025] The inner ring member 21 of this embodiment is provided with an adhesive strip 26, and the inner ring member 21 is connected to the drum paper 1 through the adhesive strip 26. Specifically, the adhesive strip 26 is provided at the bottom of the inner ring member 21, and the surface of the adhesive strip 26 is coated with double-sided tape or glue, and the inner ring member 21 and the drum paper 1 are bonded and fixed together by the double-sided tape or glue, thereby simplifying the connection structure between the two.

[0026] The moisture-proof paper 12, the plastic sheet 11, and the drum paper 1 of this embodiment are all in the shape of a rectangle or an ellipse. Specifically, the shapes of the moisture-proof paper 12, the plastic sheet 11, and the drum paper 1 can be selected to be consistent according to the actual use, and can be rectangular, elliptical, or other geometric shapes, which can reduce the thickness and size, have a high degree of shape matching, and can better enable the drum paper 1 and the hanging edge 2 to be bonded and fixed, and have a wide range of applications.

[0027] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
