Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to an ear shell angle adjustment structure and a headphone. Background Technology

[0002] Headphones typically consist of a headband, earcups, speakers, and a microphone boom. The headband is usually curved, with two earcups connected to each end. Speakers are installed inside each earcup. The microphone boom is rotatably connected to one of the earcups, allowing the user to adjust the position of the microphone at the end of the boom for ease of use.

[0003] To facilitate adjustment of the ear shell's wearing angle, existing technologies connect the headband and ear shell using a cylindrical elastic material. When worn, the combined effect of the headband's clamping force and the ear's support force on the ear shell causes the elastic material to deform, thus allowing the ear shell's wearing angle to be adjusted. However, with this adjustment method, when the wearing angle is adjusted to a large extent, the elastic material will generate a large elastic force, making it difficult to maintain a stable position and resulting in a large support force on the ear, affecting the user experience.

[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] In existing technologies, a cylindrical elastic material is used to connect the headband and the ear shell. When worn, the elastic material deforms due to the combined effect of the clamping force of the headband and the supporting force from the ear to the ear shell, which allows the wearing angle of the ear shell to be adjusted. However, with this adjustment method, the elasticity of the elastic material will affect the adjustment effect, thus affecting the user experience.

[0047] To address this issue, this embodiment provides an ear shell angle adjustment structure.

[0048] Specifically, please refer to Figures 1 to 6 The ear shell angle adjustment structure includes an ear shell 1, a first support shell 2, and a flexible member 3. The ear shell 1 is inserted into the user's cochlea, the first support shell 2 is connected to the headband, and the flexible member 3 connects the ear shell 1 and the first support shell 2. The flexible member 3 is elastic and can undergo elastic deformation under external force. A buffer groove 31 is provided on the flexible member 3, located between the ear shell 1 and the first support shell 2. When the wearing angle of the ear shell 1 is adjusted, the flexible member 3 can undergo elastic deformation to adapt to the position of the ear shell 1 relative to the user's ear. At the same time, the buffer groove 31 absorbs the elastic force generated by the deformation of the flexible member 3, ensuring the stability of the current position of the ear shell 1, making the wearing angle of the ear shell 1 easier to adjust, and reducing the support force on the ear, thereby improving the user experience.

[0049] Among them, the flexible component 3 can be made of elastic materials such as rubber or silicone, so that it is elastic and can undergo elastic deformation.

[0050] Alternatively, please refer to Figure 7In this embodiment, the flexible member 3 is a flat cylindrical shape. Along the radial direction of the flexible member 3, the flexible member 3 includes a central portion 33 and an outer edge 32. The outer edge 32 of the flexible member 3 is connected to the first support shell 2, and the central portion 33 of the flexible member 3 is connected to the ear shell 1. The buffer groove 31 is located between the central portion 33 and the outer edge 32 of the flexible member 3. This arrangement makes it easier for the flexible member 3 to deform when adjusting the wearing angle of the ear shell 1, thereby improving the adjustment effect of the wearing angle of the ear shell 1.

[0051] In other embodiments, one axial end of the flexible member 3 may be connected to the first support housing 2, and the other axial end of the flexible member 3 may be connected to the ear housing 1. The buffer groove 31 is located between the two ends of the flexible member 3.

[0052] Specifically, in this embodiment, the outer peripheral surface of the flexible member 3 is provided with an annular groove 35, and the first support housing 2 includes an annular protrusion 21, which engages with the groove 35; this arrangement can ensure the connection stability between the flexible member 3 and the first support housing 2.

[0053] Optionally, the buffer groove 31 is annular, with the center lines of the slot 35, buffer groove 31, and ball socket 34 coinciding, and the buffer groove 31 located between the slot 35 and the ball socket 34. With this configuration, when the ear shell 1 is adjusted in any direction relative to the first support shell 2, the buffer groove 31 can absorb the elastic force generated by the elastic deformation of the flexible member 3, thereby ensuring the effective adjustment of the ear shell 1's wearing angle. In other embodiments, the buffer groove 31 can also be composed of multiple grooves evenly and spaced along the circumference of the flexible member 3.

[0054] It should be noted that in this embodiment, there is one buffer groove 31. In other embodiments, the number of buffer grooves 31 can be set to multiple. The center lines of multiple buffer grooves 31 coincide, but the radii of multiple buffer grooves 31 are different. The buffer grooves 31 are nested in sequence, and multiple buffer grooves 31 are all located between the card slot 35 and the ball socket 34.

[0055] In addition, in this embodiment, the buffer groove 31 is specifically disposed on the surface of the flexible member 3 that is close to the first support housing 2 but far away from the ear housing 1; in other embodiments, the buffer groove 31 may also be disposed on the surface of the flexible member 3 that is close to the ear housing 1 but far away from the first support housing 2.

[0056] Alternatively, please refer to Figures 3 to 8 The ear shell angle adjustment structure also includes a ball protrusion 4 fixedly connected to the ear shell 1, and the flexible member 3 is also provided with a ball socket 34, into which the ball protrusion 4 is inserted. This arrangement ensures the connection stability between the flexible member 3 and the ear shell 1. Preferably, the ear shell 1 and the ball protrusion 4 are integrally formed.

[0057] In this embodiment, the ear shell 1 and the flexible member 3 are fixedly connected. The elastic deformation of the flexible member 3 allows the ear shell 1 to adjust its wearing angle relative to the first support shell 2. In other embodiments, the ear shell 1 and the flexible member 3 can be directly connected by a ball joint 4 and a ball socket 34, allowing the ear shell 1 to rotate omnidirectionally relative to the first support shell 2, thus enabling more flexible adjustment of the wearing angle of the ear shell 1.

[0058] Specifically, please refer to Figures 3 to 6 In this embodiment, the ear shell angle adjustment structure further includes a connecting post 5 fixedly connected to the ball protrusion 4. The flexible member 3 is also provided with a first through hole 36, which communicates with the ball socket 34. The connecting post 5 passes through the first through hole 36. The ear shell angle adjustment structure also includes a fixing member 6 and a connecting member 7. The fixing member 6 and the ear shell 1 are located on opposite sides of the flexible member 3. The fixing member 6 is provided with a second through hole 61, and the connecting member 7 passes through the second through hole 61 and is threadedly connected to the connecting post 5. This arrangement, through the threaded connection between the connecting member 7 and the connecting post 5, allows the fixing member 6 and the ear shell 1 to clamp the flexible member 3, thereby fixing the ear shell 1 and the flexible member 3. This ensures the stability of the connection between the ear shell 1 and the flexible member 3 and facilitates assembly and disassembly.

[0059] Alternatively, please refer to Figure 5 and Figure 6 The ear shell angle adjustment structure includes multiple connecting posts 5 and multiple connecting pieces 7. The multiple connecting posts 5 are all fixedly connected to the ball joint 4, and are evenly distributed along the center line of the ball joint 4. The flexible member 3 is provided with multiple first through holes 36, and the multiple connecting posts 5 are inserted into the multiple first through holes 36 one-to-one. The fixing member 6 is provided with multiple second through holes 61, and the multiple connecting pieces 7 are passed through the multiple second through holes 61 one-to-one, and are threadedly connected to the multiple connecting posts 5 one-to-one. This arrangement, through the cooperation of the multiple connecting pieces 7 and the multiple connecting posts 5, fixes the ear shell 1 and the flexible member 3, further improving the stability of the connection between the ear shell 1 and the flexible member 3. In this embodiment, an exemplary scheme is provided where the ear shell angle adjustment structure includes two connecting posts 5 and two connecting pieces 7. In other embodiments, the number of connecting posts 5 and connecting pieces 7 can be set as needed.

[0060] Optionally, the ear shell 1, the ball protrusion 4, and the multiple connecting posts 5 are integrally formed. This arrangement can effectively reduce the number of parts, thereby improving assembly efficiency. In other embodiments, the ear shell 1, the ball protrusion 4, and the multiple connecting posts 5 can also be separately arranged.

[0061] Optionally, the hardness of the first support shell 2 is greater than that of the flexible component 3, and the flexible component 3 is integrally formed with the first support shell 2. This configuration reduces the number of parts and facilitates processing and assembly; it also provides effective support for the ear shell 1 through the first support shell 2. Specifically, both the first support shell 2 and the flexible component 3 are made of plastic, and they can be integrally formed through a two-color injection molding process or a die-casting process. The material of the first support shell 2 can be engineering plastics with a certain degree of hardness, such as PC (polycarbonate) and / or ABS (acrylonitrile-butadiene-styrene copolymer).

[0062] Optionally, this embodiment provides a headset that includes an ear shell angle adjustment structure.

[0063] Alternatively, please refer to Figures 3 to 5 The headphones also include a speaker plate 8, a speaker 9, and an ear tip 10.
