Description

Technical Field

[0001] This utility model belongs to the field of headphone technology, specifically relating to a music headphone with a graphene speaker. Background Technology

[0002] In the field of audio technology, headphones are important sound playback devices, and their sound quality and performance directly affect the user's listening experience.

[0003] Traditional dynamic headphones typically use paper or plastic diaphragms, which have limitations in terms of sound quality, durability, and sensitivity. In recent years, graphene, as a novel nanomaterial, has attracted considerable attention due to its superior physical properties, and its application in audio equipment is gradually expanding. Graphene's lightweight, high strength, good thermal stability, and excellent mechanical properties make it an ideal material for manufacturing headphone diaphragms.

[0004] While some headphones utilize graphene diaphragms, existing headphone technology still suffers from the following shortcomings in sound quality, low-frequency response, clarity, and durability: Traditional diaphragm materials lead to sound distortion and insufficient low-frequency response. Inadequate acoustic cavity design easily generates standing waves and low-frequency reverberation, affecting sound purity. Insufficient diaphragm stability makes it prone to deformation during vibration, resulting in distortion. Headphone thermal management issues can lead to overheating during prolonged use. Insufficient structural robustness results in inadequate durability and shock resistance. Utility Model Content

[0005] The present invention aims to solve the technical problems of poor sound quality, low-frequency response, sound clarity and durability of the prior art headphones using graphene diaphragms.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A music headphone with a graphene speaker includes a headphone shell and a graphene composite diaphragm dynamic driver unit assembled inside the headphone shell. The graphene composite diaphragm dynamic driver unit includes a sound cavity, a high-magnetic sound-producing group, a graphene composite diaphragm, and a front baffle.

[0008] The sound cavity has an inverted convex shape, with a lower circular groove and an upper circular groove above and connected to the lower circular groove. The upper circular groove has an inner ring and an outer ring on its inner and outer sides, respectively. The high-magnetic sound-producing group is installed in the upper circular groove and is located between the inner and outer rings. A voice coil is located below the center of the graphene composite diaphragm and is located in the cavity of the high-magnetic sound-producing group. The front baffle is installed in the upper circular groove, located on top of the outer ring, and positioned above the graphene composite diaphragm.

[0009] Graphene's lightweight and rigid properties allow diaphragms to respond more quickly and accurately to changes in audio signals, reducing distortion and providing clearer sound quality. The low mass of the graphene diaphragm results in minimal inertia during vibration, allowing it to better follow rapid changes in audio signals and further reducing distortion. Graphene's excellent mechanical properties enable the diaphragm to produce a large sound output with relatively small actuation force, allowing headphones to operate at lower power and improving sensitivity. Graphene's strength and durability make the diaphragm more robust and less prone to damage.

[0010] Preferably, the graphene composite diaphragm is composed of a graphene film and a metal frame. The metal frame includes an annular ring located inside the high-magnetic sound-emitting group and bonded to the voice coil, and a circular cover integrally formed on top of the annular ring, featuring a central sound outlet and several auxiliary sound outlets arranged circumferentially. The metal frame provides additional support, making the diaphragm more stable when driven by audio signals. The metal frame can effectively conduct the heat generated by the graphene film, contributing to the headphone's thermal management.

[0011] Preferably, a circular hole is provided at the bottom of the sound cavity. The circular hole can improve airflow and reduce the formation of standing waves.

[0012] Preferably, the high-magnetic-coil sound-producing assembly includes an upper magnetic coil and a lower magnetic coil that form a fixed magnetic field and are combined as a pair of magnets, with the north and south poles of the upper and lower magnetic coils positioned opposite each other. This improves the driving efficiency of the voice coil, resulting in a more powerful headphone output.

[0013] Preferably, a steel passive bass cone with a central hole is placed inside the lower circular groove. The passive bass cone can increase the low-frequency response of the headphones and provide a richer bass effect.

[0014] Preferably, the front panel is evenly distributed with honeycomb holes to reduce wind noise caused by airflow when wearing the headphones.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are:

[0016] These music headphones with graphene speakers feature an inverted convex-shaped acoustic chamber. Combined with a circular bottom aperture and a passive radiator, this design effectively improves low-frequency response, providing richer bass while reducing standing waves and reverberation, resulting in clearer and more powerful low frequencies. The composite structure of the graphene diaphragm and metal frame, along with the placement of auxiliary sound outlets, optimizes sound output direction and dispersion, reducing sound reflections within the acoustic chamber and thus improving clarity and spatiality. The metal frame not only provides additional support for the graphene diaphragm but also protects it, increasing the overall structural durability and impact resistance. Simultaneously, the metal frame effectively conducts heat, aiding in the headphones' thermal management and preventing overheating during prolonged use.

[0017] The strong magnetic field design of the high-magnetic-coil driver and the relative placement of the magnetic coils improve the driving efficiency of the voice coil and reduce magnetic saturation, maintaining low distortion even at high volumes for a purer sound. The honeycomb perforation design on the front panel reduces wind noise during wear and helps with even sound diffusion, providing a more natural listening experience.

[0018] Through a graphene diaphragm and an optimized sound system, the headphones deliver clearer, lower-distortion sound, especially in the low-frequency range. The physical properties of graphene and the support of the metal frame ensure stable performance and reduced distortion even at high volumes or during extended use. The thermal conductivity of the metal frame aids in heat dissipation, preventing overheating and ensuring comfort during prolonged use. The combination of graphene and metal materials enhances the headphones' durability and shock resistance, making them more robust. Hole design and other sound optimizations provide a wider soundstage and a more natural listening experience, improving the user's listening experience. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0030] This application discloses a music headphone with a graphene speaker, including a headphone shell and a graphene composite diaphragm dynamic driver unit assembled in the headphone shell. The graphene composite diaphragm dynamic driver unit includes a sound cavity 1, a high magnetic sound group 5, a graphene composite diaphragm 2, and a front baffle 4.

[0031] The acoustic cavity 1 has an inverted convex shape, with a lower circular groove 11 and an upper circular groove 12 located above and connected to the lower circular groove 11. The upper circular groove 12 has an inner ring 13 and an outer ring 14 on its inner and outer sides, respectively. A circular hole 15 is located at the bottom of the acoustic cavity 1. The circular hole 15 improves airflow and reduces standing wave formation, thus providing better low-frequency response and reducing low-frequency reverberation. A steel passive bass cone 6 with a central hole 61 is placed inside the lower circular groove 11. The passive bass cone increases the headphone's low-frequency response, providing a richer bass effect. The passive cone helps optimize the overall sound reproduction of the headphones, especially in the low-frequency range.

[0032] The high-magnetic-coil sound-producing group 5 is installed within the upper circular slot 12 and located between the inner ring 13 and the outer ring 14. The high-magnetic-coil sound-producing group 5 includes an upper magnetic ring 51 and a lower magnetic ring 52 that form a fixed magnetic field and are combined as a pair of magnets, with the north and south poles of the upper magnetic ring 51 and lower magnetic ring 52 positioned opposite each other. The oppositely positioned north and south poles can generate a stronger magnetic field, improving the driving efficiency of the voice coil 3 and making the headphone output more powerful. The relative placement of the upper magnetic ring 51 and lower magnetic ring 52 helps reduce magnetic saturation, preventing the headphones from easily distorting even at high volumes.

[0033] The graphene composite diaphragm 2 is composed of a graphene film 21 and a metal frame 22. The metal frame 22 includes an annular ring 23 located inside the high-magnetic sound-emitting group 5 and bonded to the voice coil 3, and a circular cover 26 integrally formed on top of the annular ring 23 with a central sound outlet 24 and several circumferentially arranged auxiliary sound outlets 25. The metal frame 22 provides additional support, making the diaphragm more stable when driven by audio signals, reducing deformation caused by vibration, and thus reducing distortion. The metal frame 22 can effectively conduct the heat generated by the graphene film 21, which helps with the thermal management of the headphones and prevents overheating due to prolonged use. The metal frame 22 can protect the graphene film 21 and increase the durability and impact resistance of the overall structure. The central sound outlet 24 and the auxiliary sound outlets 25 help optimize the output direction and dispersion of sound, providing a wider sound field and a more natural listening experience. The auxiliary sound outlets 25 help reduce sound reflections inside the acoustic cavity 1, further improving sound clarity.

[0034] A voice coil 3 is located below the center of the graphene composite diaphragm 2, within the cavity of the high-magnetic sound-producing assembly 5. A front baffle 4 is installed within the upper circular groove 12, positioned on top of the outer ring 14, and above the graphene composite diaphragm 2. The front baffle 4 has evenly distributed honeycomb holes 41. This honeycomb hole design reduces wind noise caused by airflow when the headphones are worn. The honeycomb holes 41 also contribute to even sound diffusion, providing a more natural listening experience.

[0035] This music headphone with a graphene speaker uses a sound cavity 1 to optimize sound resonance and frequency response. The inverted convex structure of the sound cavity 1, along with the upper circular groove 12 and lower circular groove 11, effectively controls sound flow and reflection, enhances low-frequency performance, and reduces unnecessary resonance, thus providing a purer sound. The high-magnetic sound-producing assembly 5, installed within the upper circular groove 12, uses a strong magnetic field to move the voice coil 3 within it. When an audio signal passes through the voice coil 3, its movement in the magnetic field is converted into mechanical vibration, driving the graphene composite diaphragm 2 to vibrate, thereby producing sound. Graphene is an extremely lightweight and high-strength material; its addition allows the diaphragm to be lighter, stiffer, and thinner, resulting in a faster response and accurate reproduction of details in the audio signal. The voice coil 3 is located within the cavity of the high-magnetic sound-producing assembly 5, directly connected to the center below the graphene composite diaphragm 2. When the voice coil 3 is subjected to an audio signal, it transmits vibrations to the diaphragm, causing the diaphragm to vibrate accordingly.

[0036] Graphene's lightweight and rigid properties allow diaphragms to respond more quickly and accurately to changes in audio signals, reducing distortion and providing clearer sound quality. The low mass of the graphene diaphragm results in minimal inertia during vibration, allowing it to better follow rapid changes in audio signals and further reducing distortion. Graphene's excellent mechanical properties enable the diaphragm to produce a large sound output with relatively small actuation force, allowing headphones to operate at lower power and improving sensitivity. Graphene's strength and durability make the diaphragm more robust and less prone to damage.

[0037] This graphene speaker music headphone achieves high-quality audio output through the synergistic effect of its unique acoustic cavity 1, high-magnetic sound-emitting assembly 5, and graphene composite diaphragm 2. The inverted convex structure of the acoustic cavity 1 and the upper and lower circular slots 11 optimize sound resonance and frequency response, effectively controlling sound flow and reflection. The high-magnetic sound-emitting assembly 5 uses a strong magnetic field to induce mechanical vibration in the voice coil 3, which in turn drives the graphene composite diaphragm 2 to vibrate. The lightweight and rigid properties of graphene allow the diaphragm to respond quickly and accurately to audio signals, thus accurately reproducing the details of the audio signal.

[0038] The design of the acoustic cavity 1 not only enhances the low-frequency effect and reduces unnecessary resonance, but also improves airflow through the circular hole 15 at the bottom, reducing the formation of standing waves, providing better low-frequency response and reducing low-frequency reverberation. At the same time, the metal frame 22 on the graphene composite diaphragm 2 provides additional support, protects the graphene film 21, increases the overall structural durability and impact resistance, and also helps with thermal management to prevent overheating.

[0039] The center sound outlet 24 and auxiliary sound outlet 25 optimize the direction and dispersion of sound output, providing a wider soundstage and a more natural listening experience, while reducing sound reflections within the acoustic cavity 1 and improving sound clarity. Furthermore, the honeycomb perforation 41 on the front baffle 4 reduces wind noise and contributes to more even sound diffusion, further enhancing the listening experience. The low mass and low inertia of the graphene diaphragm, along with its excellent mechanical properties, allow the headphones to deliver a large sound output at relatively low power, improving headphone sensitivity.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
