Abstract
Description
Technical Field
[0001] This utility model relates to a loudspeaker, specifically a novel loudspeaker shell structure. Background Technology
[0002] A loudspeaker is an electroacoustic component that converts electrical signals into sound. Existing loudspeaker housings have complex and poorly designed structures, often lacking a sound-focusing design. This causes sound to disperse rapidly during propagation, resulting in poor loudness and spatial perception when it reaches the external environment. Furthermore, most existing loudspeaker housings are made of metal, which is expensive and inefficient to manufacture. Additionally, the base plate of existing loudspeaker housings can only be produced one base plate per die cycle, preventing the production of multiple base plates in a single operation. Therefore, low manufacturing efficiency hinders mass production. To address these issues, the inventors have improved the structure of the loudspeaker housing. Utility Model Content
[0003] The purpose of this utility model is to provide a novel speaker shell structure, which has the advantages of simple structure, reasonable design, and better sound concentration through the main cone base, so that the sound can be better focused towards several sound holes at the top when it bounces, thus achieving a good sound focusing effect, which is conducive to improving the loudness and spatial sense of the sound. It is also easy to injection mold, can achieve high production efficiency, and can realize the large-scale mass production of speaker shell structures, thus solving the problems mentioned in the above technical background.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel horn shell structure, which includes a frame and a horn mounted on the frame. The frame includes a main basin seat, with the top of the main basin seat being annular and the bottom being elliptical. The main basin seat is a hollow cavity structure with openings at both ends. The horn includes a tube seat, which penetrates the main basin seat from top to bottom and sits on the main basin seat. The tube seat is fixed to the main basin seat. A base plate is mounted on the tube seat, and the base plate includes a main body and multiple sound-emitting zones mounted on the main body. Each sound-emitting zone has several evenly distributed sound holes.
[0005] Preferably, the bottom of the main basin is fixed with an edge, which is located in the circumferential direction of the main basin.
[0006] Preferably, the top of the cylindrical seat is positioned above the main basin seat, and the bottom is positioned inside the cavity of the main basin seat.
[0007] Preferably, the cylindrical base is a cavity structure with an opening at the top and a hollow interior, and several through holes are provided through the cylindrical base. The several through holes are evenly distributed on the cylindrical base and are used to transmit sound.
[0008] Preferably, the circumference of the cylindrical base is provided with multiple ring-shaped steps, and the outer diameter of the multiple steps gradually decreases from top to bottom.
[0009] Preferably, a sound outlet tube is threadedly connected to the cylinder seat. The sound outlet tube has a hollow cavity structure with openings at both ends, and the cavity of the sound outlet tube is L-shaped.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a novel horn shell structure, which includes a frame and a horn mounted on the frame. The overall structure is simple and reasonably designed. The frame includes a main basin base, with a ring-shaped top and an elliptical bottom. The main basin base is a hollow cavity structure with openings at both ends. The horn includes a tube base, which extends from top to bottom through the main basin base and sits on it. The tube base is fixed to the main basin base. During operation, sound enters from the elliptical bottom of the main basin base, passes through the cavity of the main basin base, and is released from the ring-shaped top. Because the cross-sectional area of the bottom of the main basin base is larger than that of the top, the main basin base can better concentrate the sound, allowing the sound to better converge towards the several sound holes at the top when it bounces, achieving a good sound focusing effect and improving the loudness and spatial sense of the sound.
[0011] 2. The basin frame and horn in this utility model are manufactured using a specified mold. The mold includes a lower mold base and an upper mold base located above the lower mold base. A lower mold core is provided on the lower mold base, and an upper mold core corresponding to the lower mold core is provided on the upper mold base. The upper mold core is provided with multiple sets of adapter holes, which are evenly distributed on the upper mold core. When the upper mold base and the lower mold base are closed, an injection cavity with an injection base plate is formed between the upper mold core and the lower mold core. This mold can process multiple base plates with many sound holes at one time, making the new horn shell structure easy to inject and achieve high production efficiency. It can also realize the large-scale mass production of the horn shell structure and is suitable for widespread use. Attached Figure Description

The upper mold core 6 is provided with multiple sets of adapter holes 61, and the multiple sets of adapter holes 61 are evenly distributed on the upper mold core 6. When the upper mold base 4 and the lower mold base 7 are closed, an injection cavity for the injection base plate 3 is formed between the upper mold core 6 and the lower mold core 5. In this embodiment, four upper mold cores 6 and four lower mold cores 5 are provided, so that the mold can realize four cavities in one mold, and process four base plates 3 with many sound holes 321 at one time. The processing efficiency is high, and the processing efficiency is high and the cost is low compared with the traditional metal base.
