Among them, in order to improve the wearing comfort of the earphone head, the earphone structure shell and the side facing the cheek are connected with a facial mask made of soft material. The middle area of ​​the facial mask is spaced apart from the earphone structure shell, and the edge area is connected to the earphone structure shell. However, based on this structural design, in actual use, the wearing position of the earphone head is prone to shift, that is, the position of the earphone head relative to the cheek is prone to relative movement. Based on the working principle of the earphone head, the wearing position of the earphone head is required to be high, otherwise it will affect the user's hearing. Therefore, if the wearing position of the earphone head is prone to shift, it is necessary to repeatedly adjust the wearing position of the earphone head, affecting the user's experience. Summary of the invention

[0003] The purpose of the present application is to overcome the deficiencies of the above-mentioned prior art and to provide a veneer structure, which is intended to solve the problem that the wearing position of the earphone head is easily offset.

[0004] This application is implemented as follows:

[0005] A veneer structure is connected to the side of the earphone head facing the cheek, including a plurality of limiting ridges, each of which is connected to the side of the earphone head facing the cheek, each of which is made of elastic material, each of which is connected to the side of the earphone head facing the cheek, each of which extends along a first direction, and each of which is spaced apart in a second direction, wherein the first direction and the second direction are staggered.

[0006] Optionally, each of the limiting convex strips forms a fitting surface together on the side away from the earphone head, the fitting surface is curved, and the distance between the fitting surface and the earphone head gradually decreases from the middle part to the peripheral side.

[0007] Optionally, the face-mounted structure also includes a face-mounted base, which is connected to the side of the earphone head facing the cheek, and each of the limiting ridges is integrally connected to the side of the face-mounted base facing the cheek, and the face-mounted base and each of the limiting ridges are made of the same material.

[0008] Optionally, the face-attaching base is provided with a convex hull on the side facing the cheek, the convex hull on the side facing the cheek is a convex hull surface, and the surface shape of the convex hull surface in the direction facing the cheek is the same as the surface shape of the fitting surface of the corresponding area;

[0009] The ratio of the distance between the convex hull surface and the fitting surface to the thickness of the limiting convex strip is 0.75-1.25.

[0010] Optionally, the convex hull is spaced apart from at least one of the limiting convex strips on one side in the second direction, and is spaced apart from at least one of the limiting convex strips on the other side in the second direction;

[0011] Optionally, the cross-sectional shape of the fitting surface is a parabola, and the fitting surface is tangent to the side of the fitting base at a corresponding position facing the cheek at its edge.

[0012] Optionally, the surface-mounted base and the outer shell of the earphone head are separate structures, and the four sides of the surface-mounted base are connected with edging pieces extending toward the outer periphery along the outer surface of the earphone head.

[0013] Optionally, the first direction is an up-down direction.

[0014] The present application also provides an earphone head, comprising the above-mentioned veneer structure.

[0015] The present application also provides a headset, comprising the above-mentioned headphone head.

[0016] During use, the side of each limiting ridge away from the earphone head (i.e., the side facing the cheek) abuts against the cheek. Since the cheek has a certain flexibility, after the veneer structure is attached to the cheek, the cheek will form a structure complementary to each limiting ridge, that is, the cheek forms a groove structure at the position corresponding to the limiting ridge, and a convex structure is formed at the corresponding position between any two adjacent limiting ridges. The cooperation between each limiting ridge and the corresponding cheek forms two mutually meshing serrated structures, which makes the veneer structure and the cheek have a large static force. The friction force, that is, the resistance required when the earphone head with the veneer structure is offset relative to the cheek is increased. Since each limiting ridge is made of elastic material, after the veneer structure is attached to the cheek, each limiting ridge will be subjected to the reverse force of the cheek. These reaction forces will squeeze each limiting ridge and cause each limiting ridge to undergo elastic deformation and widen the side of each limiting ridge toward the cheek, thereby further increasing the static friction between the veneer structure and the cheek. That is, the resistance required when the earphone head with the veneer structure is offset relative to the cheek is further increased.

[0017] From the above, it can be seen that the technical effect of the present application is: through the structural design of the veneer structure, there is a greater static friction between the veneer structure and the cheek, which increases the resistance required when the earphone head with the veneer structure is offset relative to the cheek. This makes it less likely for the earphone head with the veneer structure to be displaced relative to the cheek, thereby ensuring the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] An embodiment of the present application provides a veneer structure, which is connected to the side of the earphone head facing the cheek so that it can directly contact the cheek through the veneer structure, wherein the earphone head includes a sound wave generating device and an earphone structure shell, the sound wave generating device is used to generate sound waves, the earphone structure shell is worn on the cheek and is located around the ear, the earphone structure shell is provided with a accommodating cavity and a sound outlet hole, the accommodating cavity accommodates the sound wave generating device, and the sound outlet hole connects the accommodating cavity to the outside and is opened in a direction pointing to the ear.

[0025] See also Figure 1 and Figure 2The veneer structure includes a plurality of limiting ridges 100, each of which is made of an elastic material, such as silicone or other materials that can be elastically deformed when subjected to external force. Since each limiting ridge 100 is made of an elastic material, each limiting ridge 100 will be deformed accordingly according to the direction and magnitude of the external force when subjected to external force. Each limiting ridge 100 is connected to the side of the earphone head facing the cheek, each limiting ridge 100 extends along a first direction, and each limiting ridge 100 is spaced apart in a second direction. In this way, in the second direction, a groove is formed between any two adjacent limiting ridges 100, wherein the first direction and the second direction are staggered.

[0026] During use, the side of each limiting ridge 100 away from the earphone head (i.e., the side facing the cheek) abuts against the cheek. Since the cheek has a certain flexibility, after the veneer structure is attached to the cheek, the cheek will form a structure complementary to each limiting ridge 100, that is, the cheek forms a groove structure at the position corresponding to the limiting ridge 100, and a convex structure is formed at the corresponding position between any two adjacent limiting ridges 100. The cooperation between each limiting ridge 100 and the corresponding cheek forms two mutually meshing serrated structures, which makes the veneer structure have a large static force against the cheek. The friction force, that is, the resistance required when the earphone head with the veneer structure is offset relative to the cheek is increased. Since each limiting ridge 100 is made of elastic material, after the veneer structure is fitted to the cheek, each limiting ridge 100 will be subjected to the reverse force of the cheek. These reaction forces will squeeze each limiting ridge 100 and cause each limiting ridge 100 to undergo elastic deformation and widen the side of each limiting ridge 100 toward the cheek, further increasing the static friction between the veneer structure and the cheek, that is, further increasing the resistance required when the earphone head with the veneer structure is offset relative to the cheek.

[0027] From the above, it can be seen that the technical effect of the present application is: through the structural design of the veneer structure, there is a greater static friction between the veneer structure and the cheek, which increases the resistance required when the earphone head with the veneer structure is offset relative to the cheek. This makes it less likely for the earphone head with the veneer structure to be displaced relative to the cheek, thereby ensuring the user experience.

[0028] It should be noted that each limiting ridge 100 is made of elastic material, which is helpful to reduce the discomfort of the user and improve the wearing comfort of the user for the earphone head with this veneer structure.

[0029] In one embodiment, see Figure 1 and Figure 2Each limiting convex strip 100 forms a fitting surface on the side away from the earphone head, and the fitting surface is curved, and the distance between the fitting surface and the earphone head gradually decreases from the middle to the peripheral side. In actual use, the fitting surface structure does not face the cheek directly, but is slightly sideways. Based on this structural design, the fitting surface structure can still keep the curved surface fitting the cheek, ensuring the wearing comfort of the user when using the earphone head with the fitting surface structure.

[0030] The cross-sectional shape of the bonding surface may be a parabola, an arc, or the like.

[0031] Specifically, in this embodiment, please refer to Figure 2 The cross-sectional shape of the fitting surface is a parabola, and the fitting surface is tangent to the side of the veneer base 200 facing the cheek at the corresponding position at its edge.

[0032] In one embodiment, see Figure 1 and Figure 2 The veneer structure also includes a veneer base 200, which is connected to the side of the earphone head facing the cheek, and each limiting convex strip 100 is integrally connected to the side of the veneer base 200 facing the cheek, and the veneer base 200 and each limiting convex strip 100 are made of the same material. There are two kinds of relationships between the veneer structure and the shell of the earphone head. One is that the veneer structure and the shell of the earphone head are separated, that is, the two are manufactured and formed separately, and because each limiting convex strip 100 is independent of each other, each limiting convex strip 100 needs to be connected to the shell of the earphone head separately, which will greatly increase the assembly difficulty of the veneer structure, thereby greatly increasing the production cost. Another way is that the veneer structure and the shell of the earphone head are integrated, that is, the two are manufactured and formed at one time. Since the shell of the earphone head is usually made of hard plastic material, a two-color injection molding process is required, but because each limiting convex strip 100 is isolated from each other, each limiting convex strip 100 needs to provide a glue injection port respectively, which will greatly increase the complexity of the mold structure, thereby greatly increasing the production cost. Based on this structural design, each limiting convex strip 100 and the veneer base 200 are an integral structure, such as a separate structure of the veneer structure and the earphone head shell. During the manufacturing process, each limiting convex strip 100 and the veneer base 200 are first integrally formed, and then the veneer base 200 is fixed to the earphone head shell, which reduces the assembly difficulty of the veneer structure. For example, if the veneer structure and the earphone head shell are an integral structure, only one glue injection port is required for the veneer structure, which greatly reduces the complexity of the mold structure. It can be seen that based on this structure, the production cost of the earphone head with the veneer structure can be greatly reduced.

[0033] In one embodiment, see Figure 1 and Figure 2The face-attaching base 200 is provided with a convex bulge 210 on the side facing the cheek, and the convex bulge 210 is a convex bulge 210 surface on the side facing the cheek. The surface shape of the convex bulge 210 surface is the same as the surface shape of the fitting surface of the corresponding area in the direction facing the cheek, that is, the closest distance from any position of the convex bulge 210 surface to the fitting surface is equal; the ratio of the spacing between the convex bulge 210 surface and the fitting surface to the thickness of the limiting convex strip 100 is 0.75-1.25. In this way, during use, the limiting convex strip 100 can be prevented from excessive bending, and two mutually meshing sawtooth structures are formed to facilitate the cooperation between each limiting convex strip 100 and the corresponding cheek.

[0034] Specifically, in the present embodiment, the convex hump 210 is spaced apart from at least one limiting convex strip 100 on one side in the second direction, and is spaced apart from at least one limiting convex strip 100 on the other side in the second direction.

[0035] In one embodiment, see Figure 1 and Figure 2 The veneer base 200 and the earphone head shell are separate structures, and the veneer base 200 is connected to the sides thereof with a edging piece 220 extending toward the outer periphery along the outer surface of the earphone head. Thus, based on this structural design, the contact surface between the earphone heads is increased by the edging piece 220, and thus, the veneer bases 200 can be mainly bonded with glue, which is conducive to simplifying the connection structure between the veneer structure and the earphone head, and is also conducive to improving the assembly efficiency of the veneer structure to the earphone head.

[0036] In one embodiment, the first direction is the up-down direction, so that the face structure can better limit the earphone head with the face structure to move in the front-back direction. When applied to headphones, since the earphone head directly abuts the cheek, the cheek limits the earphone head to move in the left-right direction, and the headband of the headphone can abut the top of the user's head, thereby limiting the earphone head from moving downward. In combination with this structural design, the earphone head can be better limited from being misaligned.

[0037] The present application also proposes an earphone head, which includes a veneer structure. The specific structure of the veneer structure refers to the above-mentioned embodiment. Since the earphone head adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0038] The present application also proposes a headset, which includes an earphone head. The specific structure of the earphone head refers to the above embodiment. Since the headset adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0039] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
