Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker paper cover equipment, in particular to a high-efficiency loudspeaker paper cover structure. Background Art

[0002] In the field of audio equipment, speakers are key components for sound output, and their performance directly affects the overall performance of the audio system. With the continuous advancement of technology and consumers' increasing requirements for sound quality, how to design more efficient and durable speaker structures has become a research hotspot in the industry.

[0003] Traditional speaker paper cover structures often have problems such as insufficient structural strength, poor heat dissipation performance, and sound distortion. Specifically, as the main part of sound radiation, the stability and rigidity of the paper cover have a vital impact on the sound quality. However, due to material properties and design limitations, traditional paper covers are prone to deformation when working for a long time or subjected to external impact, resulting in sound distortion and deterioration in sound quality. In addition, the speaker generates a lot of heat during operation. If the heat dissipation is poor, it will not only shorten the service life of the speaker, but may also cause safety hazards.

[0004] In view of this, the existing structure and defects are studied and improved, and a high-efficiency speaker paper cover structure is provided to achieve the purpose of being more practical. Utility Model Content

[0007] (2) Technical solution

[0009] Preferably, a voice coil is provided inside the paper cover, and a fixing screw is fixedly connected to the outer wall of the paper cover.

[0010] Preferably, a thread groove is fixedly provided on the outer wall of the reinforcement ring.

[0011] Preferably, hollow holes are provided inside the basin frame.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a highly efficient loudspeaker paper cover structure, which has the following beneficial effects:

[0017] 1. By providing a reinforcement ring on the basin frame and fixing a threaded groove on the outer wall of the reinforcement ring, combined with fixing screws fixed to the outer wall of the paper cover, a stable connection between the paper cover and the basin frame is achieved. This design not only enhances the overall structural stability of the speaker, but also effectively resists external impact and vibration, reduces deformation or damage caused by long-term use or harsh environments, thereby significantly improving the durability and service life of the speaker.

[0018] 2. The several strip-shaped hollow holes set inside not only reduce the weight of the basin frame, but also achieve effective heat dissipation inside the speaker. During the operation of the speaker, the voice coil and other electronic components will generate a certain amount of heat. The design of the hollow holes can effectively discharge this heat, prevent overheating, and ensure long-term stable operation of the speaker. At the same time, the hollow holes are evenly distributed in a ring shape, which is conducive to optimizing aerodynamic performance, reducing airflow resistance and eddy currents, making the sound clearer and more natural, and improving the sound quality of the speaker. In addition, the setting of the first and second elastic waves effectively buffers and adjusts the vibration of the paper cover, further improving the sound balance and sound quality performance.

[0028] Furthermore, a plurality of hollow holes 14 are provided in a strip shape.

[0029] Furthermore, the hollow holes 14 are evenly distributed in a ring shape, which helps to reduce the heat generated by the speaker during operation and improve the stability and durability of the speaker.

[0030] Furthermore, the fixing screw 11 is threadedly connected to the thread groove 13 at the lower end, and the length of the thread groove 13 is longer than the length of the fixing screw 11 .

[0031] Working principle: When the audio signal current passes through the voice coil 12, the voice coil, as a current-carrying conductor, is placed in the magnetic field composed of T iron 1, magnetic steel 2 and washer 3. According to Faraday's law of electromagnetic induction, the changing current will generate a changing force in the magnetic field. This force causes the voice coil 12 to vibrate up and down in the magnetic field. The vibration of the voice coil 12 is transmitted to the paper cover 6 through the connecting structure at its lower end. The paper cover 6 is the main part of sound radiation. Its vibration compresses and rarefies the air molecules, thereby generating sound waves. The design of the paper cover 6 has an important influence on the sound quality, volume and directivity of the sound. In order to enhance the rigidity and stability of the paper cover 6 and prevent it from deformation or damage during vibration, a reinforcement ring 5 is specially provided. The reinforcement ring 5 not only improves the structural strength of the paper cover 6, but also cooperates with the fixing screw 11 through the threaded groove 13 thereon to ensure a firm connection between the paper cover 6 and the basin frame 4, the first spring wave 7 and the second spring wave 8 As important buffering and regulating elements, they are located between the paper cover 6 and the dust cover 10. Their main function is to control the vibration amplitude and frequency response of the paper cover 6 to ensure that the speaker can output clear and balanced sound at different frequencies. The design of the elastic wave and the selection of materials have an important impact on the sound characteristics and durability of the speaker. The dust cover 10 is located on the outermost layer of the speaker and is mainly used to prevent dust, water vapor and other impurities from entering the interior of the speaker and protect the internal precision components from damage. At the same time, the design of the dust cover 10 also takes into account the diffusion and aesthetics of the sound. The basin frame 4 not only serves as the supporting frame of the entire speaker structure, but also achieves a good heat dissipation effect through the hollow holes 14 inside it. The design of the hollow holes 14 helps to reduce the heat generated by the speaker during operation and improve the stability and durability of the speaker. At the same time, the hollow holes 14 also optimize the aerodynamic performance, which helps to diffuse and propagate the sound.
