Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a wavy speaker cone. Background Technology

[0002] Currently, based on market demand, there is a trend towards thinner and lighter audio cones. In audio speakers, when the voice coil is connected to a signal, it will generate strong vibrations in the magnetic field, which will drive the cone to vibrate. The vibration of the cone forces the air to vibrate, thereby producing sound.

[0003] However, due to the trend towards thinner and lighter paper cones, their structural strength is not high, making them susceptible to damage from high-frequency vibrations. Furthermore, the contact area between the paper cone and the speaker frame does not participate in the sound production of the paper cone, resulting in a smaller area for the paper cone to vibrate and produce sound, which in turn affects the sound production and output quality of the paper cone. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wavy speaker cone.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wave-shaped speaker cone includes a cone body and a folded edge on the outer periphery of the cone body. The cone body is fixedly provided with a frame, a wooden layer and a rubber layer from bottom to top. A cavity is opened in the wooden layer. The frame and the rubber layer are separated by the cavity. The rubber layer is provided with annular protrusions distributed along the inner wall. A wave-shaped sound channel is formed between adjacent annular protrusions.

[0007] Preferably, the plurality of the protrusions are disposed on the inner wall of the rubber layer in an abutment.

[0008] Preferably, the wood layer includes rings disposed at the upper and lower ends of the basin frame, with vertical strips spaced apart between the two rings, and a cavity formed between the rings and the vertical strips.

[0009] Preferably, the basin frame, the wooden layer, and the rubber layer are bonded together with adhesive.

[0010] Preferably, a pad is provided at a distance from the lower end of the folded edge.

[0011] Preferably, the paper basin is arranged in a trumpet shape, wider at the top and narrower at the bottom.

[0012] Preferably, the folding adhesive is bonded to the outer edge of the paper basin.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model has a compact structure and reasonable design. By bonding a wooden layer to the frame, the structural strength of the paper cone is improved. A cavity is opened in the wooden layer, and a rubber layer is bonded to the wooden layer. The cavity is used to increase the vibration area, thereby improving the vibration efficiency and enhancing the sound quality of the speaker.

[0015] 2. Annular protrusions are set on the rubber layer to form a wave-shaped sound channel through adjacent annular protrusions, thereby forming a wave-shaped sound wave, which greatly improves the clarity of the sound. Attached Figure Description

[0022] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-4 As shown, a wavy speaker cone includes a cone body 1 and a folded edge 2 disposed on the outer periphery of the cone body 1. The cone body 1 is arranged in a trumpet shape with a larger top and a smaller bottom. A through hole for installation is opened in the middle of the cone body 1. The folded edge 2 is glued to the outer edge of the cone body 1.

[0024] The paper cone body 1 is fixedly provided with a basin frame 11, a wooden layer 12, and a rubber layer 14 from bottom to top. The basin frame 11, the wooden layer 12, and the rubber layer 14 are glued to each other. In addition, by gluing the wooden layer 12 onto the basin frame 11, the structural strength of the paper cone body 1 is improved, ensuring the quality of this embodiment when used for sound generation.

[0025] A cavity 13 is provided on the wooden layer 12. The basin frame 11 and the rubber layer 14 are spaced apart through the cavity 13. Specifically, the wooden layer 12 includes ring strips 121 provided at the upper and lower ends of the basin frame 11. The upper and lower ring strips 121 are bonded to the upper and lower ends of the basin frame 11 at intervals. A vertical strip 122 is connected between the two ring strips 121 at intervals. The upper and lower ends of the vertical strip 122 are respectively connected to the upper and lower ring strips 121.

[0026] A cavity 13 is formed between the ring 121 and the vertical bar 122, and a rubber layer 14 is bonded to the wooden layer 12. The cavity 13 is used to increase the vibration area, thereby improving the vibration efficiency of the paper cone and enhancing the sound quality of the speaker.

[0027] The rubber layer 14 is provided with annular protrusions 141 distributed along the inner wall. The protrusions 141 and the rubber layer 14 are integrally formed. Multiple protrusions 141 are attached to the inner wall of the rubber layer 14, and a wave-shaped sound channel is formed between adjacent annular protrusions 141. In turn, wave-shaped sound waves are formed when the sound is vibrated, which greatly improves the clarity of the sound.

[0028] The lower end of the folded edge 2 is provided with a pad 21 at intervals. The pad 21 enables the folded edge 2 to be suspended and fixed on the speaker, further improving the vibration effect of this embodiment. The structure of this embodiment is compact and reasonably designed, which improves the structural strength while ensuring its sound quality.
