[0026] The following combination Figures 1 to 5 The connection structure and the earphone device described in the embodiments of this disclosure will be described in detail.

[0027] The connection structure of the headphone device may include a connector 100. The connector 100 may be curved and may have both elasticity and rigidity; the connector 100 has a first end 101 and a second end 102 in the length direction; the first end 101 of the connector 100 is used to connect with the first housing of the headphone device; the second end 102 of the connector 100 is used to connect with the second housing of the headphone device; wherein, the connector 100 has a through hole 103 in the length direction.

[0028] The inventors discovered that the connecting structure of the headphone device has a large deformation force, which can easily cause pain to the wearer's ears during prolonged wear. In this application, the connector 100 has a through hole 103 along its length, which can reduce the deformation force of the connector 100, thereby reducing the clamping force on the headphone device and improving the wearing comfort of the headphone device.

[0029] In the embodiments of this disclosure, the connector 100 may be in the shape of a circle, rectangle, ellipse, etc. The cross-sectional shape of the connector 100 is not limited. For example, the cross-sectional shape of the connector 100 may be circular, rectangular, elliptical, etc. This disclosure does not limit this. As an example, such as... Figure 1 As shown, the cross-sectional shape of the connector 100 can be rectangular.

[0030] The connector 100 is both elastic and rigid. The elastic deformation capability of the connector 100 allows the headphone device to be easily worn on or removed from the wearer's ear. The rigidity of the connector 100 allows the headphone device to maintain a shape that matches the wearer's ear without external force, thereby improving the wearing stability of the headphone device.

[0031] The material of the connector 100 is not limited. For example, the material of the connector 100 can be metal, alloy, non-metal, etc. This disclosure does not limit this. As an example, the material of the connector 100 can be a nickel-titanium alloy; in other words, the material of the connector 100 can be a nickel-titanium shape memory alloy.

[0032] The method by which the first end 101 of the connector 100 is connected to the first housing of the headphone device is not limited. For example, the first end 101 of the connector 100 and the first housing of the headphone device can be directly connected by means of bonding, snap-fitting, welding, etc. As another example, the first end 101 of the connector 100 and the first housing of the headphone device can also be connected by other structures.

[0033] For example, such as Figure 4 As shown, the connection structure may further include: a first fixing member 210, which can be connected to the first end 101 of the connector 100 by means of bonding, snap-fitting, welding, etc.; the first fixing member 210 is used to be connected to the first housing by means of bonding, snap-fitting, welding, etc.

[0034] In this example, the cross-sectional area of ​​the first fastener 210 can be larger than the cross-sectional area of ​​the connector 100. Connecting the first fastener 210 to the first housing with a larger cross-sectional area can improve the connection strength between the first fastener 210 and the first housing. Of course, in other examples, the cross-sectional area of ​​the first fastener 210 can be less than or equal to the cross-sectional area of ​​the connector 100.

[0035] In this example, the material of the first fastener 210 is not limited. For example, the material of the first fastener 210 can be non-metallic, metallic, etc. As an example, the material of the first fastener 210 can be non-metallic, thereby reducing the weight of the headphone device.

[0036] In this example, the first fastener 210 can be integrally molded to wrap around the first end 101 of the connector 100 to improve the connection strength between the first fastener 210 and the first end 101 of the connector 100.

[0037] Here, the first fixing member 210 and the first end 101 of the connector 100 can be integrally formed by injection molding, insert molding, overmolding, or other methods. This disclosure does not limit this.

[0038] Here, as Figure 1As shown, the first end 101 of the connector 100 may have a first connecting through hole 104 in the thickness direction to connect with the first fixing member 210, so that a portion of the first fixing member 210 is located within the first connecting through hole 104, thereby improving the connection strength between the first end 101 of the connector 100 and the first fixing member 210. The number of first connecting through holes 104 is not limited. For example, the number of first connecting through holes 104 may be one, at least two, at least three, at least four, at least five, etc. The cross-sectional shape of the first connecting through hole 104 is not limited. For example, the cross-sectional shape of the first connecting through hole 104 may be circular, elliptical, rectangular, etc. As an example, the diameter of the first connecting through hole 104 may be 0.6mm to 1mm, 0.7mm to 1mm, 0.6mm to 0.9mm, etc., where the cross-section of the first connecting through hole 104 is circular.

[0039] Here, as Figure 1 As shown, the first end 101 of the connector 100 may have a first groove 106 on its side in the width direction for connection with the first fixing member 210, so that a portion of the first fixing member 210 is located within the first groove 106, thereby improving the connection strength between the first end 101 of the connector 100 and the first fixing member 210. The number of first grooves 106 is not limited. The number of first grooves 106 can be one, at least two, at least three, at least four, at least five, etc. As an example, such as... Figure 1 As shown, there are two first grooves 106, located on both sides of the first end 101 of the connector 100 in the width direction, to improve the connection stability between the first end 101 of the connector 100 and the first fixing member 210. The cross-sectional shape of the first groove 106 can be semi-circular, semi-elliptical, rectangular, etc. As an example, the radius of the first groove 106 can be 0.2mm to 1mm, 0.3mm to 1mm, 0.2mm to 0.9mm, etc., where the cross-section of the first groove 106 is semi-circular.

[0040] It should be noted that the first end 101 of the connector 100 can be provided with either the first groove 106 or the first connecting through hole 104, or it can be provided with both the first groove 106 and the first connecting through hole 104.

[0041] The method by which the second end 102 of the connector 100 is connected to the second housing of the headphone device is not limited. For example, the second end 102 of the connector 100 and the second housing of the headphone device can be directly connected by means of bonding, snap-fitting, welding, etc. As another example, the second end 102 of the connector 100 and the second housing of the headphone device can also be connected by other structures.

[0042] For example, such as Figure 4As shown, the connection structure may further include: a second fixing member 220, which can be connected to the second end 102 of the connector 100 by means of bonding, snap-fitting, welding, etc.; the second fixing member 220 is used to be connected to the second housing by means of bonding, snap-fitting, welding, etc.

[0043] In this example, the cross-sectional area of ​​the second fastener 220 can be larger than the cross-sectional area of ​​the connector 100. Connecting the second fastener 220 to the second housing with a larger cross-sectional area can improve the connection strength between the second fastener 220 and the second housing. Of course, in other examples, the cross-sectional area of ​​the second fastener 220 can be less than or equal to the cross-sectional area of ​​the connector 100.

[0044] In this example, the material of the second fastener 220 is not limited. For example, the material of the second fastener 220 can be non-metallic, metallic, etc. As an example, the material of the second fastener 220 can be non-metallic, thereby reducing the weight of the headphone device.

[0045] In this example, the second fastener 220 can be integrally molded to wrap around the second end 102 of the connector 100 to improve the connection strength between the second fastener 220 and the second end 102 of the connector 100.

[0046] Here, the second fixing member 220 and the second end 102 of the connector 100 can be integrally formed by injection molding, insert molding, overmolding, or other methods. This disclosure does not limit this.

[0047] Here, as Figure 1 As shown, the second end 102 of the connector 100 may have a second connecting through hole 105 in the thickness direction to connect with the second fixing member 220, so that a portion of the second fixing member 220 is located within the second connecting through hole 105, thereby improving the connection strength between the second end 102 of the connector 100 and the second fixing member 220. The number of second connecting through holes 105 is not limited. For example, the number of second connecting through holes 105 may be one, at least two, at least three, at least four, at least five, etc. The cross-sectional shape of the second connecting through hole 105 is not limited. For example, the cross-sectional shape of the second connecting through hole 105 may be circular, elliptical, rectangular, etc. As an example, the diameter of the second connecting through hole 105 may be 0.6mm to 1mm, 0.7mm to 1mm, 0.6mm to 0.9mm, etc., where the cross-section of the second connecting through hole 105 is circular.

[0048] Here, as Figure 1As shown, the second end 102 of the connector 100 may have a second groove 107 on its side in the width direction for connection with the second fixing member 220, so that a portion of the second fixing member 220 is located within the second groove 107, thereby improving the connection strength between the second end 102 of the connector 100 and the second fixing member 220. The number of second grooves 107 is not limited. The number of second grooves 107 can be one, at least two, at least three, at least four, at least five, etc. As an example, such as... Figure 1 As shown, there are two second grooves 107, located on both sides of the second end 102 of the connector 100 in the width direction, to improve the connection stability between the second end 102 of the connector 100 and the second fixing member 220. The cross-sectional shape of the second groove 107 can be semi-circular, semi-elliptical, rectangular, etc. As an example, the radius of the second groove 107 can be 0.2mm to 1mm, 0.3mm to 1mm, 0.2mm to 0.9mm, etc., where the cross-section of the second groove 107 is semi-circular.

[0049] It should be noted that the second end 102 of the connector 100 can be provided with either a second groove 107 or a second connecting through hole 105, or it can be provided with a second groove 107 and a second connecting through hole 105.

[0050] During use, the first end 101 of the connector 100 can move toward or away from the second end 102 of the connector 100, thereby adjusting the distance between the first end 101 and the second end 102 of the connector 100 by the relative movement of the headphone device, so that the headphone device can be worn on or removed from the wearer's ear.

[0051] With the same volume of connector 100, providing a through hole 103 along the length of connector 100 can reduce the weight and deformation force of connector 100. With the same weight of connector 100, providing a through hole 103 can also increase the cross-sectional area of ​​connector 100 along its length, thereby increasing the contact area between the two ends of connector 100 and the wearer's ear. With the same deformation force of connector 100, a larger contact area can reduce the pressure per unit area, thereby reducing the possibility of ear pain and improving the wearing comfort of the headphone device. Furthermore, a larger cross-sectional area of ​​connector 100 can increase the distribution area of ​​connector 100, thereby improving the uniformity of connector 100 distribution relative to the headphone device and the uniformity of elastic force distribution in the connection structure, further improving the wearing comfort of the headphone device.

[0052] The shape of the through hole 103 is not limited. For example, the through hole 103 can be strip-shaped; the length direction of the through hole 103 can be the same as the length direction of the connector 100, so as to reduce the weight and deformation force of the connector 100 and maximize the cross-sectional area of ​​the connector 100.

[0053] The number of through holes 103 is not limited. For example, the number of through holes 103 can be one, at least two, at least three, at least four, etc. This disclosure does not limit this. As an example, the number of through holes 103 can be at least two, and at least two through holes 103 can be spaced apart along the length direction of the connector 100, so as to both uniformly reduce the weight of the connector 100 along the length direction of the connector 100 and maximize the strength of the connector 100.

[0054] In some implementations of the embodiments of this disclosure, such as Figure 1 , Figure 2 and Figure 3 As shown, the dimension L1 of the connector 100 in the width direction can be greater than the dimension L2 in the thickness direction; the first end 101 of the connector 100 can move towards or away from the second end 102 of the connector 100; during use, the headphone device adjusts the distance between the first end 101 and the second end 102 of the connector 100 by the relative movement of the first end 101 and the second end 102 of the connector 100, so that the headphone device can be worn on or removed from the wearer's ear.

[0055] In this implementation, the moving direction of the first end 101 of the connector 100 corresponds to the thickness direction of the connector 100. Since the dimension L1 of the connector 100 in the width direction can be larger than the dimension L2 in the thickness direction, and the dimension L2 of the connector 100 in the thickness direction is set to be smaller, the relative moving force between the first end 101 and the second end 102 of the connector 100 can be reduced. In other words, the clamping force of the connector 100 can be reduced, thereby improving the wearing comfort of the headphone device. At the same time, since the dimension L1 of the connector 100 in the width direction is set to be larger, the contact area between the first end 101 and the second end 102 of the connector 100 and the wearer's ear can be increased, thereby reducing the pressure per unit area between the first end 101 and the second end 102 of the connector 100 and the wearer's ear, reducing the possibility of ear pain from pressure, and thus improving the wearing comfort of the headphone device. Of course, in other examples, the dimension L1 of the connector 100 in the width direction may be less than or equal to the dimension L2 in the thickness direction.

[0056] In this implementation, the value of the dimension L1 of the connector 100 in the width direction is not limited. For example, the dimension L1 of the connector 100 in the width direction can be 2mm to 4mm, 2mm to 3mm, 3mm to 4mm, etc. This disclosure does not limit this.

[0057] In this implementation, the value of the thickness dimension L2 of the connector 100 is not limited. For example, the thickness dimension L2 of the connector 100 can be 0.01mm to 0.03mm, 0.01mm to 0.02mm, 0.02mm to 0.03mm, etc. Or, for example, the thickness dimension L2 of the connector 100 can be 0.02mm, 0.03mm, 0.04mm, etc. This disclosure does not impose any limitations on this.

[0058] In this implementation, the through hole 103 can be provided through the thickness direction of the connector 100 to increase the area of ​​the through hole 103. A larger through hole 103 can further reduce the deformation force that causes the first end 101 of the connector 100 to move towards or away from the second end 102 of the connector 100, thereby improving the wearing comfort of the headphone device. At the same time, with the same mass of the connector 100, by providing the through hole 103 in the thickness direction of the connector 100 with a smaller dimension, the dimension L1 of the connector 100 in the width direction can be set to be larger, thereby increasing the contact area between the connector 100 and the wearer's ear, reducing the force per unit area on the wearer's ear, and thus improving the wearing comfort of the headphone device.

[0059] In this implementation, the size of the through hole 103 is not limited. The value of the dimension L3 of the through hole 103 in the width direction of the connector 100 is not limited. For example, the dimension L3 of the through hole 103 in the width direction of the connector 100 can be 1.5mm to 2mm, 1.5mm to 1.8mm, 1.8mm to 2mm, etc. This disclosure does not limit this. The value of the width L4 of the portion of the connector 100 located on one side of the through hole 103 in the width direction is not limited. For example, the width L4 of the portion of the connector 100 located on one side of the through hole 103 in the width direction can be 0.4mm to 1mm, 0.4mm to 0.8mm, 0.6mm to 1mm, etc. Here, the through holes 103 can be symmetrically arranged in the width direction of the connector 100 to improve the uniformity of the deformation capacity of the connector 100 in each region.

[0060] In some implementations of the embodiments of this disclosure, in the undeformed state, there is a first distance between the first end 101 and the second end 102 of the connector 100.

[0061] In this implementation, the value of the first distance is not limited. For example, in the undeformed state, the first distance between the first end 101 and the second end 102 of the connector 100 allows the first guard body and the second housing to be spaced apart or in contact.

[0062] In this implementation, during the wearing process of the headphone device, the distance between the first end 101 and the second end 102 of the connector 100 generally increases, thereby enabling the headphone device to have a clamping force on the wearer's ear when worn, so as to improve the wearing stability of the headphone device and prevent the headphone device from shaking during the wearing process and affecting its use.

[0063] In this implementation, since the connector 100 has a through hole 103 along its length or the thickness dimension L2 of the connector (100) is set to be small, the clamping force of the headphone device in the wearing state can be reduced, thereby improving the wearing comfort of the headphone device.

[0064] For example, in the first deformed state, there may be a second distance between the first end 101 and the second end 102 of the connector 100; the value of the second distance minus the first distance can be 2 mm; in other words, the distance between the first end 101 and the second end 102 of the connector 100 increases by 2 mm; the first end 101 and the second end 102 of the connector 100 have a first clamping force through deformation, and the first clamping force can be 8 gf to 12 gf, 8 gf to 10 gf, 10 gf to 12 gf, etc. This disclosure does not limit this. In related technologies, the first clamping force of the connector 100 without the through hole 103 is generally 18.3 gf. Here, gf is the unit of force, gram force.

[0065] For example, in the second deformed state, there is a third distance between the first end 101 and the second end 102 of the connector 100; the value of the third distance minus the first distance is 4 mm; in other words, the distance between the first end 101 and the second end 102 of the connector 100 increases by 4 mm; the first end 101 and the second end 102 of the connector 100 have a second clamping force through deformation, and the second clamping force can be 22gf to 25gf, 22gf to 24gf, 23gf to 25gf, etc. This disclosure does not limit this. In related technologies, the second clamping force of the connector 100 without the through hole 103 is generally 38.4gf.

[0066] For example, in the third deformed state, there is a fourth distance between the first end 101 and the second end 102 of the connector 100; the value of the fourth distance minus the first distance is 6 mm; in other words, the distance between the first end 101 and the second end 102 of the connector 100 increases by 6 mm; the first end 101 and the second end 102 of the connector 100 have a third clamping force through deformation, which can be 31gf to 35gf, 31gf to 33gf, 33gf to 35gf, etc. This disclosure does not limit this. In related technologies, the third clamping force of the connector 100 without the through hole 103 is generally 61gf.

[0067] In this implementation, because the clamping force of the connector 100 is reduced and the deformation capacity is increased, the number of times the connector 100 can be deformed and used is increased, and the number of times the connector 100 can be worn is increased; in other words, the connector 100 can be worn many times before failing; thus, the service life of the connector 100 can be improved.

[0068] For example, in the undeformed state, there is a first distance between the first end 101 and the second end 102 of the connector 100; in the third deformed state, there is a fourth distance between the first end 101 and the second end 102 of the connector 100; the value of the fourth distance minus the first distance is 6 mm; the connector 100 can switch from the undeformed state to the third deformed state 11,500 to 12,500 times. In other words, even with fewer than 11,500 to 12,500 times, the headphone assembly can still maintain good deformation capability and good wearing stability. Here, the connector 100 can also switch from the undeformed state to the third deformed state 11,000 to 12,000 times, 11,500 to 12,000 times, etc. This disclosure does not limit this. In related technologies, the connection structure without the through hole 103 can only switch from the undeformed state to the third deformed state about 8,000 times.

[0069] In some implementations of the embodiments of this disclosure, such as Figure 5 As shown, the connection structure may further include: a wrapping member 300, which may be elastic; the wrapping member 300 is wrapped around the connector 100; the hardness of the wrapping member 300 may be less than the hardness of the connector 100; in order to improve the wearing comfort of the headphone device.

[0070] In this implementation, the material of the packaging component 300 is not limited. For example, the material of the packaging component 300 can be soft rubber, foam, etc. As an example, the material of the packaging component 300 can be liquid silicone, TPEE / TPU, etc., where the hardness of the liquid silicone material can be from 10A to 50A; and the hardness of the TPEE / TPU material can be from 50A to 70A. This disclosure does not limit this aspect.

[0071] In this implementation, the connecting structure may further include an FPC line 400, which is movably inserted within the enclosure 300. Both ends of the FPC line 400 extend beyond the enclosure 300 along its length to connect with structural components within the first and second housings. Movable insertion of the FPC line 400 within the enclosure 300 better releases the tensile force during mechanical movement of the connecting structure, better protects the stability of the FPC line 400, and reduces the stress generated by the FPC line 400 and the enclosure 300, thus minimizing its impact on the springback flexibility of the connector 100. In other words, movable insertion of the FPC line 400 within the enclosure 300 ensures that the FPC line 400 has minimal impact on the deformation capacity of the connector 100, thereby improving the deformation capacity of the connector 100.

[0072] The FPC line 400 is more flexible than cables in related technologies, which further reduces the impact of the FPC line 400 on the deformation capacity of the connector 100, thereby improving the deformation capacity of the connection structure.

[0073] The embodiments of this disclosure also describe an earphone device, including a connection structure, a first housing, and a second housing according to the embodiments of this disclosure; a first end 101 of a connector 100 is connected to the first housing, and a second end 102 of the connector 100 is connected to the second housing.

[0074] In this embodiment, the headphone device can be an ear-hold headphone or an ear clip-on headphone. This disclosure does not limit the type of headphone device. For example, the headphone device can be an ear clip-on headphone.

[0075] In this embodiment, the headphone device may further include functional structures such as a speaker and a power supply. These functional structures may be housed within either the first housing or the second housing. As an example, the speaker may be housed within the first housing, and the power supply may be housed within the second housing.

For example, different combinations of specific technical features can form different embodiments and technical solutions.
