Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and in particular to a loudspeaker cone, a loudspeaker and a vehicle. Background Art

[0002] The cone in a loudspeaker is a key component that converts electrical signals into mechanical vibrations. The pressure changes caused by these vibrations create sound waves in the surrounding air, which in turn produces sound.

[0003] The cone (also called the cone or diaphragm) of a traditional speaker is usually made of pulp or polymer plastic materials and designed in a cone shape. In the high-frequency range, due to the large mass of the cone-shaped cone, a large inertial force will be generated when vibrating at high speed. Since the cone made of pulp or polymer plastic materials has low rigidity, this inertial force may cause the cone to bend, deform or twist, causing sound distortion. This distortion usually manifests as high-frequency distortion, unclear sound quality or changed timbre. Utility Model Content

DETAILED DESCRIPTION

[0028] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. During actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0030] At present, the cone-shaped cone of the traditional speaker can vibrate in a relatively rigid manner in the low-frequency area within the audio range of 20 Hz to 20 kHz that can be heard by the human ear, so there will be lower distortion. However, the inertial force generated at high frequencies is larger, making it impossible for the cone of the general vibrator to maintain consistent rigidity during vibration, thus causing distortion in sound reproduction.

[0031] Therefore, one of the current efforts in speaker cone design is to increase the rigidity of the cone and reduce its mass. For example, from the perspective of design material considerations, it is a high Young's modulus, low density, appropriate internal damping and light overall weight. However, to improve the material and design of the cone, it is necessary to find a balance between rigidity, lightness and cost.

[0032] like Figure 3 As shown, the utility model provides a speaker cone, including a cone assembly 10 and a dust cap 14:

[0033] The cone group 10 is an annular cone structure. It can also be considered that the cone group 10 is a cone bowl structure as a whole. The cone group 10 with an annular cone structure has better rigidity. The design of the annular structure can improve the stability of the cone during vibration, reduce distortion and reproduce the sound more accurately.

[0034] The dust cap 14 is connected to the outside of the sound cone group 10 and covers the center of the sound cone group 10, and the dust cap 14 is made of high-strength material. The dust cap 14 is located at the center of the sound cone group 10 and directly covers the top of the sound cone. Its main function is to prevent dust, debris, liquid and other external substances from entering the inside of the sound cone, thereby protecting the internal vibration system and components and ensuring the normal operation of the speaker. The dust cap 14 is usually made of high-strength material to ensure that it has sufficient stability and durability. Common materials include polymer composites, special paper or even metal. These materials have good rigidity and compression resistance, which can enhance the rigidity of the sound cone group 10 connected thereto, avoid sound distortion caused by excessive deformation of the sound cone group 10 due to high-frequency vibration, and make it more resistant to vibration and pressure, thereby maintaining the shape stability of the sound cone group 10. In this way, the sound cone can vibrate more accurately when playing high-frequency audio, maintain the clarity and accuracy of the sound, and enhance the playback effect of the speaker.

[0035] The dust cap 14 is preferably made of carbon fiber material. Carbon fiber has extremely high strength and rigidity, is light in weight, has excellent tensile strength and corrosion resistance, and can optimize sound characteristics without adding too much weight.

[0036] like Figure 1 , 2 As shown, the cone group 10 includes a first cone layer 11 and a second cone layer 12 .

[0037] The first basin layer 11 is made of carbon fiber material. By using carbon fiber to manufacture the first basin layer 11, the sound basin can have good rigidity, thereby improving the stability and accuracy of its vibration. Carbon fiber also has excellent acoustic properties, which helps to reduce the resonance frequency of the sound basin itself, thereby reducing sound distortion.

[0038] The second basin layer 12 is superimposed on the inner side or outer side of the first basin layer 11. The superposition of the second basin layer 12 can further enhance the structural strength and stability of the sound basin. The second basin layer 12 is superimposed on the inner side or outer side of the first basin layer 11 to form a composite structure, increase the overall rigidity, and thus more effectively suppress vibration and deformation. This design can also provide greater design flexibility to adapt to different acoustic requirements and space constraints.

[0039] like Figure 1 , 2As shown, the speaker further includes a third basin layer 13, which is made of carbon fiber material. The first basin layer 11, the second basin layer 12 and the third basin layer 13 are stacked in sequence from the outside to the inside. The speaker cone is divided into three layers, namely the first basin layer 11, the second basin layer 12 and the third basin layer 13. These layers are designed to enhance the structural performance of the cone or improve the characteristics of the sound.

[0040] The first basin layer 11 is the outermost layer, directly exposed to the external environment, and has waterproof, dustproof or other protective functions, and also affects the scattering or reflection of sound.

[0041] The second basin layer 12 is the main part of the sound basin, which is responsible for vibration and sound generation. This layer usually needs to have good vibration characteristics and sound conduction performance.

[0042] The third basin layer 13 is an internal structure or cushioning layer, which is used to enhance the stability of the sound basin or control vibration. It also affects the propagation and performance of sound.

[0043] like Figure 4 As shown, the first basin layer 11 and the second basin layer 12 are connected by a first adhesive layer 15, and the second basin layer 12 and the third basin layer 13 are connected by a second adhesive layer 16. The function of the first adhesive layer 15 is to firmly bond the first basin layer 11 and the second basin layer 12 together to ensure that the connection between them is tight and not easy to loosen. This helps to maintain the overall stability of the sound basin and promotes the transmission and distribution of vibrations. The second adhesive layer 16 has a similar function to the first adhesive layer 15, firmly connecting the second basin layer 12 and the third basin layer 13. This ensures that the connection between the layers of the sound basin is tight and the vibration is effectively transmitted, thereby producing clear and accurate sound.

[0044] like Figure 4 As shown, the second basin layer 12 is a porous structure, and the pore center of the porous structure is perpendicular to the basin surface of the first basin layer 11. The second basin layer 12 is made of paper material, and the porous structure is preferably a honeycomb structure. The honeycomb structure of the second basin layer 12 can make up for the problem that a single-layer carbon fiber material will leak and affect the sound effect. At the same time, the honeycomb structure has large internal damping, increases transmission loss, and can smooth curves.

[0045] like Figure 5As shown, an annular connection area is provided in the middle between the outer edge of the cone group 10 and the center of the cone group 10, and the annular connection area is connected to the outer edge of the dust cap 14. The distance from the annular connection area to the outer edge of the cone group 10 is roughly equal to the distance from the annular connection area to the center of the cone group 10. Since both the outer edge and the center of the cone group 10 need to be connected to other components, the middle area between the outer edge and the center of the cone group 10 is far away from the connection points of the two places, resulting in a lower rigidity at this position, that is, a lower rigidity of the annular connection area. Therefore, the annular connection area is connected to the dust cap 14, and the structural strength of the dust cap 14 is used to support the annular connection area, thereby improving the overall rigidity of the cone group 10.

[0046] like Figure 3 , 5 As shown in Figures 6 and 7, the dust cap 14 is a convex spherical crown structure, and the outer edge of the dust cap 14 is glued to the outer side of the first basin layer 11. The design of the dust cap 14 can be similar to the structure of an arch bridge or an arch. Arch structures are often used in engineering to provide additional support and stability because they can evenly distribute loads and resist external pressure. In this case, the spherical crown shape of the dust cap 14 will increase the overall rigidity of the sound basin group 10, thereby further improving the performance of the sound basin.

[0047] like Figure 5 , 6 As shown, the utility model also includes a speaker, including the speaker cone as described above, and also includes:

[0048] The basin frame 20 is a structural frame for placing and supporting the sound cone group 10. It is usually a metal or plastic frame that can firmly fix the sound cone group 10 and provide support and protection. The basin frame 20 can also take on the transmission and distribution function of part of the sound vibration.

[0049] The voice coil 30 is a coil wound on a bracket, which is controlled by current to generate a magnetic field and interacts with the magnet (main magnet 70) to generate sound.

[0050] The support piece 40 is an elastic element connecting the voice coil 30 and the basin frame 20, and is used to support and position the voice coil 30 to ensure its accurate movement in the magnetic field.

[0051] The magnetic conductive sheet 50 and the magnetic conductive bowl 60 together with the main magnetic steel 70 constitute a magnetic circuit system for concentrating and guiding the magnetic field so that it interacts with the voice coil 30 to generate sound.

[0052] The main magnet 70 is usually a strong magnet that generates a magnetic field, which interacts with the voice coil 30 to generate a force, causing the cone to vibrate and produce sound.

[0053] The soldering piece 80 is usually used to connect the wires of the voice coil 30 to an external connector or cable. The soldering piece 80 is usually a small piece of metal, one end of which is connected to the lead on the voice coil 30, and the other end is used to connect to an external circuit or cable.

[0054] The utility model also includes a vehicle, comprising the above-mentioned loudspeaker. The vehicle is not only a means of transportation, but also a mobile music space, providing a comfortable environment for passengers to enjoy high-quality music.

[0055] In summary, the utility model proposes a speaker cone, a speaker and a vehicle. A dust cap 14 is generally provided in the middle of the speaker cone. The dust cap 14 is provided in the middle of the cone and is connected to the outer side of the cone. In the present application, a dust cap 14 made of a high-strength material is used. This design makes the dust cap 14 a part of the cone structure, rather than just an addition. The dust cap 14 is made of a high-strength material, which can increase its rigidity and durability. The use of high-strength materials can prevent the cone from being deformed too much during high-frequency vibrations, thereby avoiding sound distortion. By using this improved cone design, the playback effect of the entire speaker system is improved. The presence of the dust cap 14 increases the structural stability of the cone, enabling it to better withstand high-frequency vibrations, thereby reducing the possibility of sound distortion.
