Description

Technical Field

[0001] The present invention relates to the technical field of audio equipment, and in particular to an earmuff and an earphone. Background Art

[0002] Earmuffs are also called headphone covers. Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears.

[0003] Optimizing sound quality and maintaining stable fit for headphones and other devices has long been a research priority. Some existing earphone covers are primarily made of a single silicone material. This material fails to effectively alter the sound path, adjust resonance, and damping, resulting in poor sound quality due to issues like high-frequency glitches and a lack of elasticity in the low frequencies. Furthermore, simple silicone covers are prone to displacement deviations and lack a secure fit, failing to meet user needs. Therefore, a technical solution to improve both sound quality and fit is urgently needed. Summary of the Invention

[0004] The purpose of the present invention is to provide an earmuff and earphone to solve the problems existing in the above-mentioned prior art and to improve the sound quality and wearing firmness.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] The present invention provides an earmuff, comprising: an earmuff body, one end of which is provided with a sound outlet, the outer surface of the earmuff body being a smooth convex curved surface structure, which can provide a certain degree of support and prevent it from slipping after entering the ear, and the smooth curved surface structure can reduce damage to the ear canal and improve wearing comfort; a hard connector, which is inserted into the earmuff body, and the hard connector is provided with a through hole along the length direction, and the inner side wall of the through hole is provided with a plurality of concave-convex structures arranged at intervals, and the hard connector can prevent the earmuff from being deformed due to extrusion and improve wearing stability; the through hole forms a sound channel, and the concave-convex structure in the through hole can cause high-frequency sound waves to form multiple different paths during propagation, so that some sound waves reach the ear earlier or later and interfere with the main sound waves, thereby enriching the high-frequency details, expanding the high-frequency upper limit, and making the sound, such as the treble part of string music, brighter and clearer, with more overtones and details. Low-frequency sound waves have longer wavelengths, and the concave-convex structure can guide them in different directions, reducing standing waves and reflections in the ear canal. This makes the low frequencies cleaner and more powerful, with deeper penetration, giving the sound a more solid and rhythmic feel, like a drumbeat. The headphone drivers may resonate during operation, affecting sound quality. The concave-convex structure increases system damping, suppressing undesirable resonances for more stable sound, clearer and more accurate across all frequency bands, and reducing ambiguity and confusion. The concave-convex structure can also alter the shape and size of the resonance cavity in the ear canal to a certain extent, optimizing the resonant frequency. This, in turn, adds a fuller, warmer sound to the mid-range vocals, achieving an optimized bandwidth.

[0007] Preferably, the concave-convex structure includes annular teeth and annular grooves, and the inner side wall of the through hole of the hard connector is sequentially provided with a plurality of the annular grooves along the axial direction, and an annular tooth is provided between two adjacent annular grooves, so that the inner side wall of the through hole forms a tooth-like structure, and the earphone sound unit may produce resonance when working, affecting the sound quality. The tooth-like structure in the through hole can increase the damping of the system, suppress unreasonable resonance, make the sound more stable, and make it clearer and more accurate in all frequency bands, reducing the ambiguity and confusion of the sound. The tooth-like structure can change the shape and size of the resonance cavity in the ear canal to a certain extent, making the resonance frequency more reasonable. For the mid-frequency human voice part, it can make the sound fuller and warmer, achieving the effect of optimizing the bandwidth. There is no limitation on the arrangement and structural form of the concave-convex structure. In other embodiments, the concave-convex structure can be directly replaced by an internal thread opened on the inner side wall of the through hole. In another embodiment, the concave-convex structure can adopt a wavy structure arranged along the axial direction of the through hole.

[0008] Preferably, the earmuff body includes an in-ear piece with a hollow cavity inside, a connecting tube is fixedly provided in the cavity of the in-ear piece, one end of the connecting tube passes through the in-ear piece to form a sound outlet, the hard connecting piece is fixedly passed through the connecting tube, and the end of the connecting tube away from the sound outlet is used for fixed connection with the earphone, and at the same time, the through structure in the connecting tube can realize the propagation of sound.

[0009] Preferably, the outer wall of the in-ear piece is a smooth curved structure, and there is a gap between the connecting tube and the inner wall of the in-ear piece. The gap allows the in-ear piece to have a certain deformation space. At the same time, in combination with the hard connecting piece, there is a certain buffer space after entering the ear canal, and no hard contact with the ear canal occurs, thereby avoiding damage to the ear canal. Furthermore, the gap can also serve as an installation space for the earmuff to be connected to the earphone, making it convenient to fix the earmuff to the earphone.

[0010] Preferably, the inner diameter of the through hole of the hard connector gradually increases from the end away from the sound outlet to the end close to the sound outlet. The variable diameter structure of the through hole makes the through hole as a whole form a trumpet-like structure. The end close to the earphone is a thinner entrance of the trumpet for sound waves to enter, and the end close to the sound outlet is a thicker exit of the trumpet for sound waves to pass out. The trumpet-like structure allows the sound to diffuse better when it is passed out, thereby improving the sound quality effect. The through hole can also improve air flow. In the high-frequency area, proper air flow can avoid the feeling of blockage caused by air compression and accumulation, making the high frequency more transparent and natural, reducing the harsh and sharp feeling, and improving the smoothness and ductility of the high frequency. For low frequencies, air flow can help low-frequency sound waves to propagate and release more smoothly, making the rebound of low frequencies faster and more powerful, enhancing the elasticity and rhythm of low frequencies, and making the heavy bass in music more dynamic.

[0011] Preferably, a sponge block is fixed in the through hole of the hard connector, which can further adjust the resonance and damping, improve air flow, eliminate high-frequency burrs and isolate echoes.

[0012] Preferably, a protective net is provided between the end of the hard connector close to the sound outlet and the sound outlet. The protective net can block the sponge block and prevent the sponge block from falling into the ear canal, thereby improving safety. There is no restriction on the material of the protective net. The protective net can be made of silicone material and integrated with the silicone earmuff. The surface can be made into a honeycomb structure with a polygonal or circular opening cross-section. The protective net can also be made of a known metal material. The protective net is located at a suitable position between the bottom of the sound outlet of the silicone earmuff and the top of the hard connector, thereby blocking the sponge block in the hard connector.

[0013] Preferably, the inner wall of the connecting tube is provided with an internal thread, and the outer wall of the rigid connector is provided with an external thread. The connecting tube and the rigid connector are connected by a thread, which makes the whole more stable. In addition, the rigid connector and the connecting tube can also be connected in other ways. For example, when the rigid connector is made of silicone material, it can be directly integrated with the connecting tube. Or, in other connection methods, the rigid connector and the connecting tube can be fixedly connected by gluing, which can also achieve a stable connection structure between the connecting tube and the rigid connector.

[0014] Preferably, the protective net is a honeycomb structure, and the open cross-section of the honeycomb structure is polygonal or circular. On the premise of protecting and blocking the sponge block, the honeycomb structure will not interfere with the transmission of sound, and the honeycomb opening structure can further change the transmission path of the sound wave, so that the sound quality is better.

[0015] The present invention also provides an earphone comprising an earphone body, the sound output end of which is fixedly connected to the earmuff described above. Without an additional fixing structure, the silicone earmuff may become misaligned due to various external forces, affecting sound transmission and wearing comfort. The rigid connector of the earmuff of the present invention effectively reduces this displacement, ensuring that the earmuff always remains in the correct position.

[0016] Compared with the prior art, the present invention has achieved the following technical effects:

[0017] The present invention provides a hard connector inside the earmuff body. The hard connector allows the flexible earmuff to be fixed in shape after entering the ear canal, avoiding displacement deviation of the silicone earmuff due to squeezing. Since the use of the hard connector reduces the problem of displacement deviation of the earmuff due to squeezing, the earmuff is firmly and reliably worn. The inner wall of the through hole of the hard connector of the present invention has multiple spaced concave and convex structures, so that high-frequency sound waves form multiple different paths during propagation. Some sound waves arrive at the ear earlier or later, interfering with the main sound waves, making the high-frequency details richer and expanding the high-frequency upper limit, making the sound, such as the treble part of string music, brighter and clearer, with more overtones and details; low-frequency sound waves have a longer wavelength, and the concave and convex structures can guide the low-frequency sound waves to diffuse in different directions, reducing the standing waves and reflections of the low-frequency sound in the ear canal, making the low-frequency sound cleaner, more powerful, and deeper, like a drum beat with a more solid and rhythmic sound; the earphone sound unit may produce resonance when working, affecting the sound quality. The concave-convex structure increases system damping, suppressing undesirable resonances for a more stable sound, providing clarity and accuracy across all frequency bands while reducing ambiguity and confusion. The concave-convex structure also modifies the shape and size of the resonance cavity within the ear canal, optimizing the resonant frequency. This, in turn, adds a fuller, warmer sound to the mid-range vocals, optimizing the bandwidth and ultimately improving sound quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide an earmuff and earphone to solve the problems existing in the above-mentioned prior art and to improve the sound quality and wearing firmness.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Existing earmuffs are generally made of silicone material, which has a sound channel inside. The whole earmuff is easily deformed and offset due to squeezing, and the sound quality is poor. In order to solve this problem, the present invention provides an earmuff, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, it includes an earmuff body 1, one end of which is provided with a sound outlet 101. The earmuff body 1 can be made of silicone material, or other flexible materials, such as rubber; a hard connector 2 is inserted into the earmuff body 1, and the hard connector 2 is provided with a through hole 201 connected to the sound outlet 101 along the length direction, and the inner wall of the through hole 201 is provided with a plurality of concave and convex structures arranged at intervals. Traditional silicone earmuffs may easily loosen or slip during use, especially in situations such as exercise. The present invention is provided with a hard connector 2 inserted into the earmuff body 1. The hard connector 2 allows the flexible earmuff to be fixed in shape after entering the human ear, avoiding displacement deviation of the silicone earmuff due to squeezing, and significantly improving the stability of the earmuff, ensuring that it will not shift easily when worn. Since the use of the hard connector 2 reduces the problem of displacement deviation of the earmuff due to squeezing, it makes it firm and reliable to wear. The inner wall of the through hole 201 of the hard connector 2 of the present invention has a plurality of concave-convex structures arranged at intervals, so that high-frequency sound waves form multiple different paths during the propagation process. Some sound waves reach the ear earlier or later, and interfere with the main sound waves, making the high-frequency details richer, expanding the high-frequency upper limit, and making the sound such as the treble part of string music brighter, clearer, and with more overtones and details; the low-frequency sound waves have a longer wavelength, and the concave-convex structure can guide the low-frequency sound waves to diffuse in different directions, reducing the standing waves and reflections of the low frequency in the ear canal, making the low frequency cleaner and more powerful, and diving deeper, like the drum sound is more solid and rhythmic, thereby improving the sound quality.

[0030] There is no limitation on the arrangement and structure of the concave-convex structure. In one embodiment, the concave-convex structure can be directly replaced by an internal thread provided on the inner wall of the through hole 201. In another embodiment, the concave-convex structure can be a wave-shaped structure arranged along the axial direction of the through hole 201. Figure 3 As shown, in a preferred embodiment, the concave-convex structure includes a plurality of annular teeth and a plurality of annular grooves. The inner wall of the through hole 201 of the hard connector 2 is provided with a plurality of annular grooves in sequence along the axial direction, and an annular tooth is provided between two adjacent annular grooves, thereby forming a tooth-shaped structure 202 on the side wall of the through hole 201.

[0031] The sound unit of an earphone may produce resonance during operation, affecting sound quality. The tooth-shaped structure 202 of the rigid connector 2 increases system damping, suppressing undesirable resonances and making the sound more stable. This structure also reduces ambiguity and confusion by altering the shape and size of the resonance cavity within the ear canal to a certain extent, making the resonance frequency more reasonable. This, in turn, makes the mid-frequency vocal part sound fuller and warmer, achieving the effect of optimizing the bandwidth.

[0032] Furthermore, the tooth-shaped structure 202 within the through-hole 201 of the rigid connector 2 also improves air flow. In the high-frequency region, proper air flow prevents the sense of sound congestion caused by air compression and accumulation, making high frequencies more transparent and natural, reducing harshness and sharpness, and enhancing the smoothness and ductility of high frequencies. For low frequencies, air flow helps low-frequency sound waves propagate and release more smoothly, making the rebound of low frequencies faster and more powerful, enhancing the elasticity and rhythm of low frequencies, and making the deep bass in music more dynamic.

[0033] In one embodiment, in order to improve the comfort of in-ear wear, the earmuff body 1 is made of silicone material, which includes an in-ear piece 103 with a hollow cavity inside. A connecting tube 102 is fixedly provided in the cavity of the in-ear piece 103. A sound channel is formed inside the connecting tube 102. One end of the connecting tube 102 passes through the in-ear piece 103 to form a sound outlet 101. The hard connector 2 is fixedly inserted into the connecting tube 102. The hard connector 2 and the connecting tube 102 are coaxially arranged, and the through hole 201 of the hard connector 2 replaces the original channel of the connecting tube 102 to form a new The sound channel allows the sound waves to be transmitted through the through hole 201 of the hard connector 2, and in the process flows through the toothed structure 202 on the side wall of the through hole 201, thereby improving the sound quality. In order to make the sound propagation smoother and further improve the sound quality, in one embodiment, the inner diameter of the through hole 201 of the hard connector 2 gradually increases from the end away from the sound outlet 101 to the end close to the sound outlet 101, forming a structure with an outward eight-shaped radial cross section. The overall through hole 201 is similar to a trumpet, and the trumpet-shaped structure further improves the sound quality effect at the sound outlet 101.

[0034] In one embodiment, the outer wall of the in-ear piece 103 is a smooth curved structure, and there is a gap between the connecting tube 102 and the inner wall of the in-ear piece 103. The gap can be used to fix the earphone. Specifically, the in-ear piece 103 is a bowl-shaped structure. The mouth of the bowl-shaped structure is used to connect the earphone, the bottom of the bowl-shaped structure is used to form the sound outlet 101, and the connecting tube 102 is fixed in the bowl-shaped structure. Silicone earmuffs may easily loosen or slip during use, especially in situations such as exercise, and are more prone to displacement deviation. In this embodiment, after adding a hard connector 2 to the earmuff, it is tightly combined with the earmuff body, which can significantly improve the stability of the earmuff on the earphone and ensure that it will not shift easily when worn. Without an additional fixing structure, the silicone earmuff may become inaccurately positioned due to various external forces, affecting sound conduction and wearing comfort. The hard connector 2 of this embodiment can effectively reduce this displacement deviation, so that the silicone earmuff can always remain in the correct position.

[0035] When using headphones, high-frequency glitches and echoes may occur. In order to avoid this problem, in one embodiment, a sponge block 3 is fixed in the through hole 201 of the hard connector 2. The sponge block 3 is adapted to the structure of the through hole 201 of the hard connector 2, and can further adjust the resonance and damping, improve air flow, eliminate high-frequency glitches and isolate echoes.

[0036] Since the sponge is a structure that is easily deformed, it may be squeezed and deformed when it is set in the earmuff, and then enter the ear from the sound outlet 101, causing a safety hazard. In order to avoid this problem, in one embodiment, a protective net 4 is provided between the end of the hard connector 2 close to the sound outlet 101 and the sound outlet 101. The protective net 4 can block the sponge block 3 and prevent the sponge block 3 from falling into the ear canal, thereby improving safety.

[0037] In one embodiment, to enhance the secureness of the connection, the inner wall of the connecting tube 102 is provided with an internal thread, and the outer wall of the rigid connector 2 is provided with an external thread. The connecting tube 102 and the rigid connector 2 are connected by a thread, which provides a more stable overall structure. In addition, the rigid connector 2 and the connecting tube 102 can also be connected in other ways. For example, when the rigid connector 2 is made of silicone material, it can be directly integrated with the connecting tube 102. Alternatively, in other connection methods, the rigid connector 2 and the connecting tube 102 can be fixedly connected by gluing.

[0038] In addition to silicone, the hard connector 2 of the present invention can also be made of copper, aluminum, titanium, stainless steel, and other materials. Similarly, the material of the protective net 4 is not limited. The protective net 4 can also be made of silicone and integrated with the silicone earmuff. The surface can be made into a honeycomb structure with a polygonal or circular opening cross-section. The protective net 4 can also be made of a known metal material. The protective net 4 is located at a suitable position between the sound outlet 101 of the silicone earmuff and the top of the hard connector 2, thereby blocking the sponge block 3 inside the hard connector 2.

[0039] Based on the above, the present invention further provides an earphone comprising an earphone body, the sound output end of which is fixedly connected to the earmuff described above. When sound propagates through the earphone via the earmuff, the toothed structure 202 on the through hole 201 of the hard connector 2 changes the sound propagation path, thereby optimizing high-frequency propagation and enhancing low-frequency effects. In conjunction with the sponge block 3 within the through hole 201, resonance and damping can be adjusted, harmful resonance can be suppressed, and sound quality can be optimized. The sponge block 3 can also eliminate high-frequency burrs and isolate echoes, and the protective net 4 can prevent the sponge block 3 from falling into the ear canal. When worn, the hard connector 2 enhances wearing stability and reduces displacement deviation.

[0040] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
