A type of headphone that improves sound quality

Abstract

This application relates to the field of electronic product technology, and more particularly to a pair of headphones for improving sound quality. The headphones include: an audio output section, which includes an audio output shell and an audio output component. The audio output shell includes a receiving cavity and a sound outlet hole. The audio output component is disposed within the receiving cavity, and the sound outlet hole is used to export the audio signal generated by the audio output component from the receiving cavity to the outside. A through-hole mesh is disposed at the sound outlet hole. When the headphones are worn, there is a gap between the through-hole mesh corresponding to at least the sound outlet hole and the user's skin. By ensuring a gap between the through-hole mesh corresponding to at least the sound outlet hole and the user's skin when the headphones are worn, foreign objects are less likely to fall onto the corresponding sound outlet mesh. Simultaneously, it prevents the sound outlet hole from becoming blocked due to dirt or cosmetic buildup when the user rubs against the audio output shell, reducing the possibility of sound outlet blockage and thus improving sound quality.

Description

Technical Field

[0001] This application relates to the field of electronic product technology, and more particularly to a pair of headphones with improved sound quality. Background Technology

[0002] Currently, many headphones on the market experience a common problem: after a period of use, the sound outlet holes on the steel mesh of the earpiece become clogged, causing the sound to become quieter or even disappear. The root cause of this clogging is that the sound outlet holes on the steel mesh are generally located on a flat surface. During use, the edges of these holes easily come into contact with the skin. Dirt and grime from the body, such as a mixture of sweat and dust after exercise, or cosmetics, can easily rub off onto the steel mesh, causing clogging and affecting the sound quality of the headphones.

[0029] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Furthermore, "many" in this application means two or more. Moreover, the term "at least one" in this application means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. Furthermore, the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0031] Currently, many headphones on the market experience a common problem: after a period of use, the sound outlet holes on the steel mesh of the earpiece become clogged, causing the sound to become quieter or even disappear. The root cause of this clogging is that the sound outlet holes on the steel mesh are generally located on a flat surface, flush with the mesh. This makes it easy for the human body to come into contact with the sound outlet holes. Dirt from the human body, such as a mixture of sweat and dust after exercise, or cosmetics, can easily rub off onto the steel mesh, causing the sound outlet holes to become clogged.

[0032] Therefore, this application provides a perforated mesh and an earphone. To enable those skilled in the art to better understand the technical solution of this application, the technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an earphone provided in an embodiment of this application. Figure 2 yes Figure 1This is a partial cross-sectional structural diagram of the earphone 100. The earphone 100 includes an audio output section 110 and a through-hole mesh 10. The audio output section 110 includes an audio output shell 120 and an audio output component 130. The audio output shell 120 includes a receiving cavity and a sound outlet 122. The audio output component 130 is the main sound-generating component within the earphone 100, converting digital signals such as electrical signals into sound for the user to hear. The audio output component 130 is housed within the receiving cavity, and the sound outlet 122 is used to export the audio signal generated by the audio output component 130 from the receiving cavity to the outside. The audio output shell 120 protects the audio output component 130 and adapts to the user's wearing shape. It houses the audio output component 130 within the receiving cavity and is shaped for easy wearing. The through-hole mesh 10 is disposed at the sound outlet 122. When the earphone 100 is worn, there is a gap between at least the portion of the through-hole mesh 10 corresponding to the sound outlet 122 and the user's skin. The through-hole mesh 10 blocks the sound outlet hole 122, allowing sound to pass through while preventing larger foreign objects from falling into the accommodating cavity through the sound outlet hole 122, damaging the audio output component 130, or affecting the sound quality of the headphones 100. When the headphones 100 are worn, part of the audio output shell 120 will be in contact with the user's skin. There is a gap between the part of the through-hole mesh 10 corresponding to the sound outlet hole 122 and the user's skin; that is, the part of the through-hole mesh 10 corresponding to the sound outlet hole 122 that is in contact with the user's skin is spaced apart.

[0034] By ensuring that there is a gap between the through-hole mesh 10 corresponding to the sound outlet 122 and the user's skin when the earphone 100 is in the wearing state, foreign objects are less likely to fall onto the through-hole mesh 10 corresponding to the sound outlet 122. At the same time, it prevents the sound outlet 122 from being blocked due to dirt or cosmetics accumulation when the human body scratches the audio output shell 120, thereby reducing the possibility of sound outlet blockage and improving sound quality.

[0035] Please see Figure 3 , Figure 3 yes Figure 1The diagram shows a schematic of the structure of an audio output shell 120 according to one embodiment of region A. In this embodiment, the audio output shell 120 includes a groove 121, and a sound outlet hole 122 is disposed on the sidewall of the groove 121. At least a portion of the through-hole mesh is disposed on the sidewall of the groove 121, and the audio signal is output to the outside from the sidewall of the groove 121. In this embodiment, the groove 121 is arranged in a gradually tapering shape from the opening to the bottom. In other embodiments, the sidewall of the groove 121 may be vertically arranged, or it may be arranged in a gradually tapering shape from the bottom to the opening. The shape of the groove 121 may be waist-shaped, or it may be circular, elliptical, rectangular, or other polygonal structures. The shape of the groove 121 can be determined according to actual usage requirements. In this embodiment, there are multiple sound outlet holes 122, distributed on the sidewall of the groove 121. In other embodiments, the sound outlet hole 122 may be a single, continuous hole surrounding the sidewall of the groove 121.

[0036] Please see Figure 4 , Figure 4 yes Figure 1 The diagram shows a schematic of the structure of an audio output shell 120 according to another embodiment of region A. In this embodiment, the audio output shell 120 includes a groove 121, and an audio output hole 122 is disposed at the bottom of the groove 121, through which the audio signal is output to the outside. Similarly, the shape of the groove 121 can be oblong, circular, elliptical, rectangular, or other polygonal structures. There are multiple audio output holes 122, distributed at the bottom of the groove 121. Alternatively, in other embodiments, the audio output hole 122 is a single, larger through hole.

[0037] Please see Figure 5 , Figure 5 yes Figure 1 The diagram shows a schematic of the audio output shell 120 in another embodiment of region A. Similar to the previous embodiment, in this embodiment, the audio output shell 120 includes a groove 121, and a sound outlet hole 122 is disposed at the bottom of the groove 121, through which the audio signal is output to the outside. However, unlike the previous embodiment, in this embodiment, the entire bottom of the groove 121 is the sound outlet hole 122. That is, the sound outlet hole 122 is surrounded by the sidewall of the groove 121.

[0038] Please see Figure 6 , Figure 6 This is a schematic diagram of a perforated mesh structure provided in an embodiment of this application.

[0039] The through-hole mesh 10 includes a cylindrical portion 12. The cylindrical portion 12 is a cylindrical structure with openings on opposite sides. This cylindrical structure can be a circular structure where both the first end 123 and the second end 124 are the same size, or it can be an elliptical cylindrical structure where both ends 123 and 124 are the same size. The cross-sectional shape of the cylindrical portion along its axial direction can be straight, curved, wavy, or broken. When it is curved, it can be an inwardly concave curve with the middle portion closer to the axis at both ends, or an outwardly convex curve with the middle portion farther from the axis at both ends. Besides circles and ellipses, the shapes of the first end 123 and the second end 124 of the cylindrical portion 12 can also be quadrilaterals such as waist-shaped, square, rectangle, parallelogram, and trapezoid, or other polygons. The specific shape can be determined according to actual needs and is not limited here. Furthermore, the first end 123 and the second end 124 of the cylindrical portion 12 can also be similar shapes of different sizes. For example, both the first end 123 and the second end 124 of the cylindrical portion 12 are circular, but the diameter of the circle at the first end 123 is larger or smaller than the diameter of the circle at the second end 124. Alternatively, the first end 123 and the second end 124 of the cylindrical portion 12 can also be different shapes. For example, the first end 123 of the cylindrical portion 12 is circular, while the second end 124 is square.

[0040] In practical applications, the cylindrical part 12 can be installed vertically on the sound outlet of the headphone 100, with the first end 123 relatively close to the external environment and the second end 124 relatively far away from the external environment, so that most of the cylindrical part 12 is not easily scratched or touched by the outside world in practical applications.

[0041] A sound outlet 14 is provided on the cylindrical portion 12. The sound outlet 14 is a through hole, allowing sound to propagate outward through the cylindrical portion 12. Simultaneously, because the sound outlet 14 is located on the cylindrical portion 12, dust and other foreign objects will generally move in the same direction under the influence of gravity. The cylindrical structure of the cylindrical portion 12 prevents dust and other foreign objects from easily remaining or accumulating on the entire cylindrical portion 12, thus preventing the sound outlet 14 from becoming blocked. In some application scenarios, after exercise, the user's skin surface has a mixture of sweat and dust. Even if the user comes into contact with the outer edge of the cylindrical portion 12, the height difference prevents the sound outlet 14 from easily becoming contaminated, thus preventing it from being blocked. In practical applications, the sound outlet 14 can be a circular hole, an elliptical hole, a rectangular hole, an oblong hole, etc. Its size can be adjusted according to actual needs and is not limited here. However, in the axial direction of the cylindrical portion, the length of the sound outlet 14 must be less than the length of the cylindrical portion 12.

[0042] This perforated mesh 10 can be connected with Figures 2 to 4 Combined with any of the embodiments. When this through-hole mesh 10 and Figure 2 When the illustrated embodiment and other embodiments in which the sound outlet through-hole 122 is disposed on the side wall of the groove 121 are combined, the sound outlet 14 is disposed corresponding to the sound outlet through-hole 122. When this through-hole partition 10 is combined with... Figure 4 When the embodiment shown is combined with other embodiments in which the sound outlet hole 122 is disposed at the bottom of the groove 121, the cylindrical portion 12 is disposed at an inclination relative to the side wall of the groove 121. The closer it is to the bottom of the groove 121, the larger the gap between the cylindrical portion 12 and the side wall of the groove 121. This prevents the side wall of the groove 121 from blocking the sound outlet hole 14 of the through hole mesh 10, so that the sound outlet hole 14 of the through hole mesh 10 can connect with the sound outlet hole 122.

[0043] Please see Figure 7 , Figure 7 This is a schematic diagram of another through-hole mesh structure provided in an embodiment of this application. In some embodiments, the through-hole mesh 10 includes a connecting portion 13 connected to the cylindrical portion 12. The cylindrical portion 12 may be inclined relative to the connecting portion 13, that is, the included angle formed at the connection between the cylindrical portion and the connecting portion 13 is an acute angle or an obtuse angle. Alternatively, the cylindrical portion 12 may be perpendicular to the connecting portion 13. The connecting portion 13 is connected to at least one end of the cylindrical portion 12. When the cylindrical portion 12 is inclined relative to the connecting portion 13, it is best if the cylindrical portion 12 is inclined backward, forming an obtuse angle with the connecting portion 13, which facilitates the guidance of sound to propagate to the external environment and helps the sound to diffuse outward. At the same time, this arrangement makes the cylindrical portion 12 easier to clean and maintain. When the cylindrical portion 12 is perpendicular to the connecting portion 13, when dust or other foreign objects fall onto the through-hole mesh 10, they are less likely to adhere to the cylindrical portion 12, which can effectively reduce the occurrence of blockage of the sound outlet 14.

[0044] In some embodiments, the connecting portion 13 includes a first connecting portion 131 and a second connecting portion 132. The first connecting portion 131 is an annular structure, and at least a portion of the first end 123 of the cylindrical portion 12 is connected to the inner edge of the first connecting portion 131. At least a portion of the second end 124 of the cylindrical portion 12 is connected to the outer edge of the second connecting portion 132. Preferably, the inner ring shape of the first connecting portion 131 is the same as the shape of the first end 123 of the cylindrical portion 12. In this case, the first connecting portion 131 is disposed around the cylindrical portion 12, completely surrounding the cylindrical portion 12. Alternatively, the first connecting portion 131 is a non-closed annular structure with one or more openings formed thereon, connecting only to a portion of the first end 123 of the cylindrical portion 12. Preferably, the second connecting portion 132 can be an integral sheet-like structure or plate-like structure, and the shape of the outer edge of the second connecting portion 132 can be the same as the shape of the second end 124 of the cylindrical portion 12, thereby connecting the entire second end 124 of the cylindrical portion 12. Alternatively, multiple notches may be formed on the second connecting portion 132, so that the outer edge has a different shape from the second end 124 of the cylindrical portion 12, and only the second end 124 of the cylindrical portion 12 is connected. The specific shapes of the first connecting portion 131 and the second connecting portion 132 can be determined according to the actual structure of the earphone 100. The longer the connection length between the first connecting portion 131 and / or the second connecting portion 132 and the first end 123 and / or the second end 124 of the cylindrical portion 12, the more stable the connection between the first connecting portion 131 and / or the second connecting portion 132 and the cylindrical portion 12.

[0045] Besides the case where the connecting portion 13 includes both the first connecting portion 131 and the second connecting portion 132, the connecting portion 13 may also include only the first connecting portion 131 or only the second connecting portion 132. The first connecting portion 131 and the second connecting portion 132 are located on two different planes. The first connecting portion 131 can serve as the top wall of the through-hole mesh 10 connecting to the edge of the first end 123 of the cylindrical portion 12, and the second connecting portion 132 can serve as the bottom wall of the through-hole mesh 10 connecting to the edge of the second end 124 of the cylindrical portion 12. It is understood that there is a height difference between the planes where the first connecting portion 131 and the second connecting portion 132 are located, and the magnitude of the height difference depends on the shape and size of the cylindrical portion 12.

[0046] In some embodiments, the through-hole mesh 10 can be circular, elliptical, oblong, or polygonal. When the connecting portion 13 includes a first connecting portion 131, the outer edge shape of the first connecting portion 131 can be the same as or different from the inner edge shape. When the connecting portion 13 does not include the first connecting portion 131, the shape of the through-hole mesh 10 mainly depends on the shape of the first end 123 of the cylindrical portion 12. The shape of the through-hole mesh 10 determines its installation method and space adaptability in the equipment. Diverse shape options can accommodate various equipment designs and space requirements, and also improve installation convenience and the aesthetics of the equipment.

[0047] In some embodiments, the connecting portion 13 and the cylindrical portion 12 are integrally formed. The through-hole mesh 10 can be manufactured without assembly, using a one-time molding process, such as stamping, where a stamping die causes plastic deformation of the planar material. The planar material extends downwards from the middle to form the cylindrical portion 12 and the connecting portion 13. The connecting portion 13 may include only the first connecting portion 131, only the second connecting portion 132, or both. This integral structure makes the through-hole mesh 10 more robust and reliable, and also offers higher production efficiency compared to other connected structures.

[0048] In some embodiments, the cylindrical portion 12 is connected to the first connecting portion 131 and the cylindrical portion 12 is connected to the second connecting portion 132 by chamfering. The chamfering makes the transition between the cylindrical portion 12 and the first connecting portion 131 and the cylindrical portion 12 and the second connecting portion 132 smoother, making it easier to clean, and the absence of sharp edges can prevent scratching the human body.

[0049] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of a sound outlet provided in an embodiment of this application.

[0050] In some embodiments, the sound outlet 14 includes an inner hole 141 and an outer hole 142. On a projection plane perpendicular to the central axis of the sound outlet 14, the projection of the inner hole 141 lies within the projection of the outer hole 142. The outer hole 142 is the opening of the sound outlet 14 on the side of the cylindrical portion 12 facing the external environment, and the inner hole 141 is the opening of the sound outlet 14 on the side of the cylindrical portion 12 facing the internal environment. The shape of the inner hole 141 can be the same as the shape of the outer hole 142. For example, the outer hole 142 is an oblong hole, and the inner hole 141 is also an oblong hole. Alternatively, the shape of the inner hole 141 can be different from the shape of the outer hole 142. For example, the outer hole 142 is an oblong hole, and the inner hole 141 is a rectangular hole. The shapes of the outer hole 142 and the inner hole 141 can be determined according to actual needs. The projection of the inner hole 141 onto the projection plane perpendicular to the central axis of the sound outlet 14 is located within the projection of the outer hole 142. It can be understood that the shape of the sound outlet 14 is similar to that of a horn. This structural design is conducive to the sound spreading outward through the sound outlet 14, and even if dust and other debris adhere to or accumulate on the sound outlet 14, they will most likely only accumulate at the outer hole 142, and will not enter the inside of the headphone 100 through the inner hole 141, thereby affecting the sound quality or service life of the headphone 100.

[0051] In some embodiments, multiple sound outlet holes 14 are provided, and the multiple sound outlet holes 14 are spaced apart. Preferably, the multiple sound outlet holes 14 are evenly distributed on the cylindrical portion and are arranged around the second connecting portion 132.

[0052] The number of sound outlets 14 can be designed according to actual application conditions, which is understandable. The number of sound outlets 14 affects the propagation and diffusion of sound. Setting multiple sound outlets 14 and surrounding the connecting part 13 can make the sound more dispersed and uniform during propagation. Different acoustic effects can also be achieved by adjusting the number and distribution of the sound outlets 14. The sound outlets 14 surrounding the connecting part 13 can allow sound to propagate in any direction through the cylindrical part 12. Especially when the sound outlets 14 are relatively far from the external environment, when the headphones 100 are in use, dirt on the through-hole mesh 10 can only block part of the sound outlets 14 near the bottom of the cylindrical part 12 due to gravity, while the other part of the sound outlets 14 can still work normally. If there is too much dirt, it will be very easy to notice.

[0053] In some embodiments, the through-hole mesh 10 further includes a fixing part 11, which is connected to the first connecting part 131. The cylindrical part 12 is connected to the fixing part 11 through the first connecting part 131. The fixing part 11 is arranged in a direction perpendicular to the first connecting part 131. The function of the fixing part 11 is to connect to the external structure and fix the position of the through-hole mesh 10 on the external structure. The fixing part 11 can be connected to the external structure by embedding, or by pasting, snap-fitting, interference fit, ultrasonic welding, etc. The fixing part 11 can be a complete annular wall. For example, the fixing part 13 can be a cylindrical structure, arranged around the first connecting part 131, with one end connected to the first connecting part 131. Other adaptive adjustments can also be made, such as forming multiple notches at the connection position of the first connecting part 131. These notches can be used to cooperate with other structures of the earphone 100 for fixation, thereby enhancing the stability of the connection with external devices or simplifying the installation process.

[0054] The cylindrical portion 12, the first connecting portion 131, and the fixing portion 11 cooperate to form a recessed structure. The audio output shell 120 includes a protruding structure, which cooperates with the recessed structure to connect the through-hole mesh to the audio output shell 120. Here, the cylindrical portion 12 and the fixing portion 11 can cooperate to clamp the protruding structure of the audio output shell 120, thereby forming a snap-fit ​​engagement. Alternatively, adhesive can be added here to connect the through-hole mesh 10 to the audio output shell 120 by means of bonding.

[0055] In some embodiments, the perforated mesh 10 is made of metal. Metal materials can improve the durability and corrosion resistance of the perforated mesh 10. For example, commonly used metal materials such as stainless steel or aluminum alloy can be selected. These materials also possess a certain degree of ductility, are suitable for stamping processes, and have durability and corrosion resistance, effectively resisting the effects of humidity and pollutants in the environment.

[0056] In another implementation, to cooperate Figure 3 and Figure 4The audio output shell 120, or other audio output through-holes 122, is disposed at the bottom of the groove 121. A through-hole mesh can also be disposed at the bottom of the groove. The through-hole mesh has sound holes corresponding to the sound output through-holes. The through-hole mesh is a cylindrical structure with an opening on one side, corresponding to the opening of the groove 121. The sidewall of the through-hole mesh is connected to the sidewall of the groove 121, and the bottom wall of the through-hole mesh is connected to or corresponds to the bottom of the groove 121. The earphone 100 also includes a fixing part connected to the opening of the through-hole mesh. The fixing part is an annular structure and is connected to the audio output shell. The fixing part and the through-hole mesh are an integral structure. The sidewall of the through-hole mesh can refer to the cylindrical part 12 of the through-hole mesh 10 in the above embodiment, and the fixing part can refer to the first connecting part 131 and the fixing part 11 of the through-hole mesh 10 in the above embodiment.

[0057] The earphone 100 provided in this embodiment can be an in-ear earphone or a non-in-ear earphone; it can be a wired earphone or a wireless earphone. The through-hole mesh 10 is connected to the audio output shell 120. The top of the through-hole mesh 10 can be flush with or slightly lower than the outer surface of the audio output shell 120. Due to the structural characteristics of the through-hole mesh 10, it can effectively prevent the sound outlet from being blocked by the accumulation of dirt and other substances.

[0058] It is worth noting that the accompanying drawings are only for illustrating the structural and connection relationships of this application, and do not limit the specific specifications or layout of the utility model product of this application.

[0059] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
