Description

Technical Field

[0001] This application belongs to the field of headphone technology, specifically relating to a headphone driver and headphone assembly. Background Technology

[0002] In-ear headphones offer good sound isolation and are favored by users. In-ear headphones consist of the earphone body and ear tips. The ear tips are placed over the sound outlet of the earphone body and are inserted into the user's ear canal during use.

[0003] In related technologies, earphone tips typically adjust their shape by deforming upon contact with the ear canal to fit different users' ear canal shapes. However, this deformation causes the earphone tip to exert a certain force on the ear canal, reducing the comfort of wearing the earphones. Utility Model Content

[0004] This application aims to provide an earphone driver and earphone assembly to solve the problem of poor wearing comfort of existing earphone drivers.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, this application discloses an earphone driver, the earphone driver comprising:

[0007] The earphone body includes a sound outlet.

[0008] Earphone cover, the earphone cover being fitted over the sound outlet;

[0009] A movable component, the movable component being connected to the earphone cover;

[0010] and an operating element connected to the moving component;

[0011] When the operating component receives a user operation, the moving component causes the earphone cover to deform.

[0012] Secondly, this application discloses an earphone assembly, including:

[0013] Charging case and individual earbuds;

[0014] The earphone unit is disposed in the charging case, which is used to charge the earphone unit.

[0015] In this embodiment, the earphone unit includes an earphone body, an earphone cover, a moving component, and an operating component. The moving component is connected to the earphone cover, and the operating component is connected to the moving component. The user can use the operating component to cause the moving component to deform the earphone cover. In this way, when the user wears the earphone, they can first adjust the earphone cover to a suitable shape through the operating component and the moving component before wearing the earphone. This avoids excessive pressure on the ear canal when the earphone cover changes its shape by its own deformation, thus improving the comfort of wearing the earphone.

[0030] This application provides an earphone unit 1, and the earphone unit of this application will be described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1-6 The earphone unit 1 provided in this application embodiment may specifically include: an earphone body 10, the earphone body 10 including a sound outlet 101; an earphone cover 20, the earphone cover 20 being fitted onto the sound outlet 101; a moving component 30, the moving component 30 being connected to the earphone cover 20; and an operating component 40, the operating component 40 being connected to the moving component 30; wherein, when the operating component 40 receives a user operation, the moving component 30 causes the earphone cover 20 to deform.

[0032] Specifically, the earphone cover 20 is made of a flexible material, and the operating component 40 can be a button, knob, or other form of input device to receive user operations. When the user wears the earphone unit 1, the earphone cover 20 is inserted into the ear canal. Before wearing the earphone unit 1, the user can operate the operating component 40 according to adjustment needs. The operating component 40 receives the user's operation and transmits it to the moving component 30. The moving component 30 causes the earphone cover 20 to deform according to the received operation, which can adjust the shape of the earphone cover 20 so that the earphone cover 20 can fit the shape of the user's ear canal.

[0033] In this embodiment, the earphone unit 1 includes an earphone body 10, an earphone cover 20, a moving component 30, and an operating component 40. The moving component 30 is connected to the earphone cover 20, and the operating component 40 is connected to the moving component 30. The user can use the operating component 40 to cause the moving component 30 to deform the earphone cover 20. This allows the user to adjust the earphone cover 20 to a suitable shape before wearing the earphone, avoiding excessive pressure on the ear canal caused by the earphone cover 20 deforming itself, thus improving wearing comfort. Furthermore, users do not need to replace earphone covers 20 of different sizes to meet the comfort needs of different users when wearing the earphone unit 1, reducing the cost of the earphone unit 1 and saving resources.

[0034] Optionally, the moving component 30 includes a moving mechanism 301 and a connecting line 302; the operating element 40 is connected to the moving mechanism 301; one end of the connecting line 302 is wound around the moving mechanism 301, and the other end of the connecting line 302 is connected to the earphone cover 20; when the operating element 40 receives a user operation, the moving mechanism 301 drives the connecting line 302 to retract or extend, so as to change the shape of the earphone cover 20.

[0035] Specifically, such as Figures 2-6 As shown, the operating component 40 is fixedly connected to one end of the moving mechanism 301. One end of the connecting wire 302 is wound around the moving mechanism 301, and the other end of the connecting wire 302 is fixedly connected to the earphone cover 20. When the user operates the operating component 40, the moving mechanism 301 drives the connecting wire 302 to retract or extend. As the moving mechanism 301 retracts or extends, the connecting wire 302 is wound or released on the moving mechanism 301, thereby pulling or releasing the earphone cover 20. This pulling or releasing can change the shape of the earphone cover 20, making the earphone cover 20 fit the user's ear canal better. In this embodiment, the shape of the earphone cover 20 can be adjusted through the moving mechanism 301 and the connecting wire 302. Before wearing the earphone unit 1, the shape of the earphone cover 20 can be changed through the connecting wire 302 and the moving mechanism 301, so that the earphone unit 1 can adapt to the ear canal shape of different users, improving the comfort of wearing the earphone.

[0036] Optionally, the connecting wire 302 is connected to the earphone cover 20 in a loop; the moving mechanism 301 drives the connecting wire 302 to extend and retract, so as to change the radial dimension of the earphone cover 20.

[0037] like Figures 2-6 As shown, the earphone cover 20 has an arc-shaped structure. A portion of the connecting wire 302 forms a loop coil, which is connected to the outer or inner side of the earphone cover 20. The other end is wound around the moving mechanism 301. Driven by the moving mechanism 301, the connecting wire 302 is wound or unwound on the moving mechanism 301, causing the diameter of the loop coil to decrease or increase. This allows the earphone cover 20 to be pulled or loosened, changing its radial dimension, i.e., its diameter. In practical applications, by making the connecting wire 302 looped around the earphone cover 20, the radial dimension of the earphone cover 20 can change uniformly, ensuring that the earphone cover 20 fits the user's ear canal in all directions. This allows the earphone unit 1 to better adapt to different users' ear canal shapes, further improving the comfort of wearing the earphones.

[0038] Optionally, the earphone cover 20 includes an inner cover 201 and an outer cap 202 that are integrally connected. The inner cover 201 is fitted onto the sound outlet 101, and the outer cap 202 is fitted onto the outside of the inner cover 201. The connecting wire 302 is connected to the outer cap 202 in a loop. The moving mechanism 301 drives the connecting wire 302 to retract and extend, so as to change the radial dimension of the outer cap 202.

[0039] Specifically, the inner sleeve 201 and the outer cap 202 are an integrated structure, which improves the stability of the earphone sleeve 20 structure. The inner sleeve 201 is fitted onto the sound outlet 101, and the outer cap 202 is fitted onto the outside of the inner sleeve 201. The outer cap 202 can cover and protect the inner sleeve 201. The outer cap 202 can be in the form of an arc-shaped cover structure, which can generate slight and uniform pressure on the ear canal to ensure the comfort of wearing the earphone unit 1.

[0040] The connecting wire 302 is connected in a loop to the inner wall of the outer cap 202. Driven by the moving mechanism 301, the connecting wire 302 is wound or released on the moving mechanism 301, thereby pulling or loosening the circumference of the outer cap 202, changing the radial dimension of the outer cap 202, thereby changing the diameter of the earphone cover 20 and improving the comfort of wearing the earphone.

[0041] The connecting cable 302 is attached to the outer cap 202. Specifically, the connecting cable 302 can be attached to the earphone cover 20 using double-sided tape, strong adhesive, etc., so that the connecting cable 302 can be fixed to the earphone cover 20. In practical applications, the adhesive method can eliminate the need for complex mechanical connectors or clip designs, making the overall structure of the earphone cover 20 simpler, reducing the number of parts, and lowering production costs.

[0042] Optionally, the operating element 40 is an adjustment knob, and the moving mechanism 301 includes a rotating rod; the adjustment knob is fixedly connected to one end of the rotating rod, the other end of the rotating rod is rotatably connected to the headphone body 10, and one end of the connecting wire 302 is wound around the rotating rod.

[0043] like Figures 3-6 As shown, the adjustment knob can be circular or elliptical. It can be fixed to the rotating rod via welding, snap-fit, or other methods, or it can be an integral part of the rotating rod. The rotating rod can be rotatably connected to the earphone body 10 via bearings or other rotating connectors, allowing it to rotate freely relative to the earphone body 10. One end of the connecting wire 302 can be wound around the connecting rod. When the user rotates the adjustment knob, the rotating rod rotates accordingly, and the connecting wire 302 winds around the rotating rod. At this time, the diameter of the loop of the connecting wire 302 on the earphone sleeve 20 gradually decreases, leading to a decrease in the diameter of the earphone sleeve 20 and thus a reduction in its radial dimension. When it is necessary to adjust the diameter of the earphone sleeve 20, the knob is rotated in the opposite direction. The connecting wire 302 wound around the rotating rod will then loosen, reducing the restriction of the loop of the connecting wire 302 on the diameter of the earphone sleeve 20. Through the elasticity of the earphone sleeve 20 itself, the diameter of the earphone sleeve 20 can then be increased.

[0044] In this embodiment, the radial dimension of the earphone cover 20 is adjusted by adjusting the button, adjusting rod, and connecting wire 302, which can improve the comfort of wearing the earphone. In addition, the structure is simple and the cost is reduced because the adjustment is only made by adjusting the button, adjusting rod, and connecting wire 302.

[0045] Optionally, the operating element 40 is an adjustment knob, and the moving mechanism 301 includes a first rotating rod 3011 and a second rotating rod 3013. The first rotating rod 3011 and the second rotating rod 3013 are rotatably connected to the headphone body 10. The first rotating rod 3011 and the second rotating rod 3013 are spaced apart, and the adjustment knob is connected to the first rotating rod 3011. One end of the connecting wire 302 is wound around the second rotating rod 3013. The first rotating rod 3011 is provided with a first main gear 3012a, and the second rotating rod 3013 is provided with a corresponding first adjusting gear 3014. The first main gear 3012a and the first adjusting gear 3014 mesh with each other.

[0046] like Figures 3-6 As shown, both the first rotating rod 3011 and the second rotating rod 3013 are rotatably connected to the headphone body 10 via bearings or other rotating connectors. The first rotating rod 3011 and the second rotating rod 3013 are arranged parallel to each other, and there is a certain distance between the first rotating rod 3011 and the second rotating rod 3013, so that the first main gear 3012a and the first adjusting gear 3014 can mesh with each other.

[0047] When the user rotates the adjustment knob, the first rotating rod 3011 rotates accordingly. The first main gear 3012a drives the first adjusting gear 3014 to rotate, which in turn drives the second rotating rod 3013 to rotate. At this time, the connecting wire 302 will wind around the second rotating rod 3013 as the rotation occurs, gradually reducing the diameter of the loop of the connecting wire 302 on the earphone cover 20. This reduction in diameter leads to a decrease in the diameter of the earphone cover 20, thus reducing its radial dimension. When it is necessary to adjust the diameter of the earphone cover 20, the adjustment knob is rotated in the opposite direction. The connecting wire 302 wound around the second rotating rod 3013 will then loosen, reducing the restriction of the loop of the connecting wire 302 on the diameter of the earphone cover 20. Through the elasticity of the earphone cover 20 itself, the diameter of the earphone cover 20 can then be increased. In this way, the force is transmitted through the first main gear 3012a and the first adjusting gear 3014, which can convert a small rotation angle into a larger linear motion or radial change, providing more refined and precise control. This design makes the adjustment process more delicate and smooth, and can better adapt to the ear canal needs of different users.

[0048] Optionally, the headphone body 10 is provided with a volume control 102, and the moving mechanism 301 further includes a third rotating rod 3015. The third rotating rod 3015 is rotatably connected to the headphone body 10 and is spaced apart from the first rotating rod 3011. The first rotating rod 3011 is also provided with a second main gear 3012b, and the third rotating rod 3015 is provided with a second adjusting gear 3016. One end of the second adjusting gear 3016 is connected to the volume control 102, and the other end of the second adjusting gear 3016 is connected to the second main gear 3012b. The wheels 3012b are staggered; the first rotating rod 3011 is movable in a direction close to or away from the second adjusting gear 3016; when the operating member 40 receives a user operation, the first rotating rod 3011 moves in a direction away from the second adjusting gear 3016, causing the second adjusting gear 3016 and the second main gear 3012b to mesh, and the second main gear 3012b drives the second adjusting gear 3016 to rotate, so as to adjust the volume of the headphone body 10 through the volume adjusting member 102.

[0049] Specifically, one end of the third rotating rod 3015 can be rotatably connected to the headphone body 10 through a bearing or other rotating connector, and the other end of the third rotating rod 3015 is provided with a second adjusting gear 3016. The second adjusting gear 3016 is connected to the volume adjustment component 102 provided on the headphone body 10. The volume of the headphone body 10 can be adjusted by adjusting the volume adjustment component 102.

[0050] The other end of the second adjusting gear 3016 is staggered with the second main gear 3012b, so that the two maintain a certain distance from each other, so that the two gears are not fully aligned or meshed in the initial state, preventing them from accidentally contacting or interfering with each other when not in operation.

[0051] The first rotating rod 3011 is movable relative to the headphone body 10 in a direction close to or away from the second adjusting gear 3016.

[0052] When a user needs to adjust the headphone volume, the user first pulls the operating component 40, causing the first rotating rod 3011 to move away from the second adjusting gear 3016, so that the second main gear 3012b moves and meshes with the second adjusting gear 3016. At this time, the user then rotates the operating component 40, causing the second main gear 3012b to drive the second adjusting gear 3016 to rotate. The rotation of the second adjusting gear 3016 drives the volume adjustment component 102 to move, thereby adjusting the volume of the headphone body 10.

[0053] It should be noted that the specific structure of the volume control 102 can refer to the prior art, and this application does not make any specific limitations on it.

[0054] Optionally, the second adjusting gear 3016 is provided with two adjusting plates 30161 spaced apart, and the volume adjusting component 102 is provided with a switch, which is located between the two adjusting plates 30161; when the operating component 40 receives a user operation, the second adjusting gear 3016 rotates, causing the two adjusting plates 30161 to drive the switch to move, so as to adjust the volume of the headphone body 10.

[0055] Specifically, such as Figure 6 As shown, the second adjusting gear 3016 is provided with two adjusting plates 30161 spaced apart. The two adjusting plates 30161 can be cylindrical, rectangular or other shaped protrusions. The volume adjustment component 102 is provided with a switch, which is clamped between the two adjusting plates 30161. When the second adjusting gear 3016 rotates, it drives the two adjusting plates 30161 to rotate, so that the switch moves with the rotation of the adjusting plates 30161. The movement of the switch is transmitted to the volume adjustment component 102, thereby realizing the adjustment of the volume of the headphone body 10.

[0056] In some alternative embodiments, the headphone body 10 is provided with a receiving cavity 103, the moving component 30 is disposed in the receiving cavity 103 and extends at least partially out of the receiving cavity 103 to be connected to the operating component 40 and the headphone cover 20.

[0057] like Figures 3-6 As shown, the headphone body 10 is provided with a receiving cavity 103. One end of the first rotating rod 3011 of the moving assembly 30 passes through the receiving cavity 103 and is rotatably connected to the side wall of the receiving cavity 103, and the other end of the first rotating rod extends out of the receiving cavity 103 and is connected to the operating member 40. A first main gear 3012a and a second main gear 3012b are arranged at intervals on the portion of the first rotating rod 3011 located in the receiving cavity 103, such that the first main gear 3012a and the second main gear 3012b are also arranged in the receiving cavity 103. The second rotating rod 3013 of the moving assembly 30 is arranged in the receiving cavity 103, and one end of the second rotating rod 3013 is connected to the side wall of the receiving cavity 103. The side wall of the receiving cavity 103 is rotatably connected, and the other end of the second rotating rod 3013 is provided with a first adjusting gear 3014. The third rotating rod 3015 of the moving component 30 is also provided in the receiving cavity 103, and one end of the third rotating rod 3015 is rotatably connected to the side wall of the receiving cavity 103. The other end of the third transmission rod 3015 is provided with a second adjusting gear 3016. The volume adjustment component 102 is also provided in the receiving cavity 103. In this way, the moving component 30 can be protected by the headphone body 10 to avoid damage to the moving component 30. Furthermore, the moving component 30 is located in the receiving cavity 103, which makes the structure of the headphone body 10 more compact.

[0058] In summary, the earphone unit 1 described in this application embodiment may include at least the following advantages:

[0059] In this embodiment, the earphone unit 1 includes an earphone body 10, an earphone cover 20, a moving component 30, and an operating component 40. The moving component 30 is connected to the earphone cover 20, and the operating component 40 is connected to the moving component 30. The user can use the operating component 40 to cause the moving component 30 to deform the earphone cover 20. This allows the user to adjust the earphone cover 20 to a suitable shape before wearing the earphone, avoiding excessive pressure on the ear canal caused by the earphone cover 20 deforming itself, thus improving wearing comfort. Furthermore, users do not need to replace ear tips of different sizes to meet the comfort needs of different people, reducing the cost of the earphone unit 1 and saving resources.

[0060] This application also provides an earphone assembly, such as...
