Description

Technical Field

[0001] This disclosure relates to the field of audio playback device technology, and more particularly to a pair of headphones. Background Technology

[0002] Among related technologies, clip-on headphones have become an important branch of the open-back headphone field in recent years. Clip-on headphones are held in place by the user's ear through their own clamping structure. Clip-on headphones offer better comfort and have become increasingly popular among users recently.

[0003] However, the limited available installation space inside the headphone shell, coupled with the fact that rotating connection structures often require a large amount of installation space, increases the design difficulty of installing internal headphone components. Utility Model Content

[0004] To overcome the problems existing in the related technology, this disclosure provides an earphone.

[0005] According to some embodiments of the present disclosure, an earphone is provided, the earphone comprising: a first housing for accommodating a battery;

[0006] A bracket is fixedly connected to the first housing. The bracket includes a pivot portion and a first edge facing the battery. The pivot portion is provided with a receiving groove. The shape of the first edge matches the shape of the battery.

[0007] A connector having an end portion rotatably connected to the rotating shaft portion;

[0008] A rotating shaft, wherein the end of the connector and the rotating shaft portion are sleeved on the rotating shaft, and the rotating shaft passes through the receiving groove;

[0009] A spring is disposed in the receiving groove and sleeved on the rotating shaft. When the rotating shaft rotates relative to the connecting member, the spring is compressed.

[0010] In some embodiments, the spring includes:

[0011] A spring body, wherein the spring body is disposed within the receiving groove;

[0012] The first elastic arm is connected to the spring body, extends out of the receiving groove, and abuts against the surface of the rotating shaft.

[0013] The second elastic arm is connected to the spring body, extends out of the receiving groove, and is fixedly connected to the end of the connector;

[0014] When the rotating shaft rotates relative to the connecting member, the rotating shaft pushes the first elastic arm to rotate relative to the second elastic arm, thereby compressing the spring body.

[0015] In some embodiments, the end of the connector is provided with a first limiting portion and a second limiting portion, and the first limiting portion and the second limiting portion are arranged along the rotation direction of the rotating shaft relative to the connector.

[0016] The bracket includes a third limiting part, which is disposed on the rotating shaft and located between the first limiting part and the second limiting part;

[0017] When the rotating shaft rotates relative to the connector, the third limiting part slides between the first limiting part and the second limiting part, and limits the angular range of rotation of the rotating shaft relative to the connector.

[0018] In some embodiments, the third limiting portion extends along a first plane, which is parallel to the radial direction of the rotation axis.

[0019] In some embodiments, the end of the connector is provided with a through hole;

[0020] The second elastic arm passes through the through hole.

[0021] In some embodiments, the battery is cylindrical;

[0022] The first edge is an arc-shaped edge.

[0023] In some embodiments, the support further includes:

[0024] The fixing part is fixedly connected to the rotating shaft part;

[0025] The fixing part includes a first connecting part, which is fixedly connected to the first housing.

[0026] The hardness of the fixing part is greater than that of the first shell.

[0027] In some embodiments, the fixing portion further includes a second connecting portion disposed adjacent to the first connecting portion;

[0028] The earphone includes a circuit board, which is fixedly connected to the second connecting part.

[0029] In some embodiments, the connection method between the first connecting part and the first housing includes one or more of screw connection, adhesive connection, welding connection and snap-fit ​​connection;

[0030] The connection method between the second connecting part and the circuit board includes one or more of screw connection, adhesive connection, welding connection and snap-fit ​​connection.

[0031] In some embodiments, the support is a metal or ceramic component.

[0032] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: This disclosure provides a receiving groove in the rotating shaft of the bracket and makes the spring sleeved on the rotating shaft passing through the receiving groove, which reduces the installation space occupied by the spring. By matching the shape of the first edge with the shape of the battery, the integrated design of the spring, bracket and battery is realized, reducing the total installation space of the spring, bracket and battery, improving the installation space utilization rate of the first housing, and realizing the rotational connection structure between the first housing and the connector with a smaller installation space.

[0047] The principles and spirit of this disclosure will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are given merely to enable those skilled in the art to better understand and implement this disclosure, and are not intended to limit the scope of this disclosure in any way.

[0048] It should be noted that although the terms "first," "second," etc., are used herein to describe different modules, steps, and data in the embodiments of this disclosure, these terms are only for distinguishing between different modules, steps, and data, and do not indicate a specific order or degree of importance. In fact, the terms "first," "second," etc., can be used interchangeably.

[0049] In related technologies, clip-on headphones often form a clamping structure through the structural layout of the headphones themselves. The clamping structure can include at least structural components as clamping ends and connecting bridges for connecting different clamping ends. In order to save space inside the headphones, the connecting bridge part of the clip-on headphones is often configured as an elastic component. However, this limits the appearance material of the connecting bridge part of the headphones, making it difficult to use hard materials such as metal to improve the texture and aesthetics of the appearance.

[0050] In view of the above, some embodiments of this disclosure provide an earphone.

[0051] Figure 1 This is a schematic diagram of the structure of an earphone according to some embodiments of the present disclosure. Figure 2 This is a schematic diagram of the structure of an earphone according to some embodiments of the present disclosure. Figure 3 This is an exploded view of an earphone according to some embodiments of the present disclosure.

[0052] In some embodiments, such as Figures 1 to 3 As shown, the headphones include: a first housing 3, a bracket 1, a connector 4, a rotating shaft 5, and a spring 6.

[0053] The first housing 3 can be used to house the battery 10.

[0054] The bracket 1 can be fixedly connected to the first housing 3, and the bracket 1 can include a pivot portion 101 and a first edge 103 facing the battery 10. The pivot portion 101 can be provided with a receiving groove 100.

[0055] Figure 4 This is a schematic diagram of the structure of an earphone stand according to some embodiments of the present disclosure. Figure 5 This is a schematic diagram of the structure of an earphone stand according to some embodiments of the present disclosure. Figure 6 This is a schematic diagram illustrating the structure of a hidden lower housing and circuit board of an earphone according to some embodiments of the present disclosure.

[0056] like Figures 4 to 6 As shown, the shape of the first edge 103 can match the shape of the battery 10, thereby improving the space utilization of the bracket 1 and the battery 10, reducing the installation space required for the bracket 1 and the battery 10, and thus providing more installation space for the headphones.

[0057] Figure 7 This is a schematic diagram illustrating the connection structure of a headphone stand and connector according to some embodiments of the present disclosure.

[0058] like Figure 7 As shown, connector 4 can be a connection structure used to connect the first housing 3 and other headphone components.

[0059] The connector may have an end, and the end of the connector 4 may be rotatably connected to the rotating shaft 101. The end of the connector 4 and the rotating shaft 101 are sleeved on the rotating shaft 5, and the end of the connector 4 may rotate around the rotating shaft 5.

[0060] The rotating shaft 5 can pass through the receiving groove 100, the spring 6 can be set in the receiving groove 100, and the spring 6 can be sleeved on the rotating shaft 5. By setting the spring 6 in the receiving groove 100 and sleeved on the rotating shaft 5, the integration of the rotating shaft part 101, the spring 6 and the rotating shaft 5 is improved, the installation space required for the rotating shaft part 101, the spring 6 and the rotating shaft 5 is reduced, the space utilization of the housing is improved, and the rotational connection structure between the first housing 3 and the connector 4 is realized with a smaller installation space.

[0061] When the first housing 3 and the rotating shaft 101 rotate relative to the connecting member 4 under the action of external force, the spring 6 can be compressed, accumulating elastic potential energy.

[0062] When the external force disappears, the compressed spring 6 can drive the first housing 3 and the rotating shaft 101 to rotate in opposite directions relative to the connecting member 4, thereby completing the clamping action.

[0063] In some embodiments, such as Figures 1 to 3As shown, the headphones may also include a second housing 2, one end of the connector 4 may be fixedly connected to the second housing 2, and the other end of the connector 4 may be rotatably connected to the bracket 1 fixedly connected to the first housing 3, so that the first housing 3 and the bracket 1 may rotate relative to the second housing 2 and the connector 4 around the rotation axis 5.

[0064] The first housing 3, the connector 4, and the second housing 2 can form a clamping structure. For example, the first housing 3, the connector 4, and the second housing 2 can form a U-shaped or V-shaped clamping structure.

[0065] The first housing 3 can be used to house electronic components such as sensing elements, battery 10 and circuit board 14, while the second housing 2 can be used to house the headphone speaker.

[0066] Figure 12 This is a schematic diagram illustrating the structure of a headphone connector according to some embodiments of the present disclosure.

[0067] In some embodiments, such as Figure 3 and Figure 12 As shown, a wire 13 can be embedded inside the connector 4. One end of the wire 13 extends into the first housing 3 and is connected to electronic components such as the battery 10 and circuit board 14 inside the first housing 3. The other end of the wire 13 extends into the second housing 2 and is connected to the speaker inside the second housing 2. The headphones can transmit electrical energy and audio signals to the speaker inside the second housing 2 through the wire 13 so that the speaker can work normally.

[0068] In some embodiments, such as Figure 2 and Figure 3 As shown, the first housing 3 may include an upper housing 11 and a lower housing 12, which together form a space for accommodating electronic components such as sensing elements, batteries 10 and circuit boards 14.

[0069] In some embodiments, such as Figure 1 , Figure 3 and Figure 12 As shown, the connector 4 may include multiple arc-shaped structures, at least two of which intersect each other and are connected at the intersection point. The connector 4 may include a first end 411 and a second end 412, which are respectively disposed on opposite sides of the rotating shaft portion 101. The rotating shaft 5 may sequentially pass through the first end 411, the rotating shaft portion 101, and the second end 412. The first end 411 and the second end 412 can form a stable triangular structure with the intersection point of the arc-shaped structures of the connector 4, thereby improving the connection stability between the connector 4, the first housing 3, and the bracket 1.

[0070] Figure 8This is a schematic diagram of the structure of a spring in an earphone according to some embodiments of the present disclosure.

[0071] In some embodiments, such as Figure 8 As shown, the spring 6 includes: a spring body 60, a first elastic arm 61, and a second elastic arm 62.

[0072] The spring body 60 can be used as an elastic potential energy storage element, and the spring body 60 can be set in the receiving groove 100.

[0073] The first elastic arm 61 can be connected to the spring body 60, and the first elastic arm 61 can extend out of the receiving groove 100 and abut against the surface of the rotating shaft 101.

[0074] The second elastic arm 62 can be connected to the spring body 60, and the second elastic arm 62 can extend out of the receiving groove 100 and be fixedly connected to the end of the connector 4.

[0075] When the rotating shaft 101 rotates relative to the connecting member 4 in the first direction under the action of external force, the rotating shaft 101 can push the first elastic arm 61 to rotate relative to the second elastic arm 62 around the rotating shaft 5 in the first direction, thereby causing the spring body 60 to undergo elastic deformation and accumulate elastic potential energy.

[0076] When the external force disappears, the compressed spring body 60 can drive the rotating shaft 101 and the first housing 3 to rotate around the rotating shaft 5 through the first elastic arm 61. The direction of rotation is a second direction opposite to the first direction, thereby enabling the earphone to complete the clamping action.

[0077] Figure 9 This is a schematic diagram illustrating the connection structure of a headphone stand and connector according to some embodiments of the present disclosure. Figure 10 This is a schematic diagram illustrating the connection structure of a headphone stand and connector according to some embodiments of the present disclosure.

[0078] In some embodiments, such as Figure 3 , Figure 9 and Figure 10 As shown, the end of the connector 4 may be provided with a first limiting part 401 and a second limiting part 402, and the first limiting part 401 and the second limiting part 402 may be arranged sequentially along the rotation direction of the rotating shaft part 101 relative to the connector 4.

[0079] The bracket 1 may include a third limiting part 701, which may be disposed on the rotating shaft part 101 and may be located between the first limiting part 401 and the second limiting part 402.

[0080] When the rotating shaft 101 rotates relative to the connecting member 4, the third limiting part 701 can slide between the first limiting part 401 and the second limiting part 402.

[0081] like Figure 9 As shown, when the rotating shaft 101 rotates relative to the connecting member 4 about the rotating shaft 5 in the second direction, the third limiting part 701 moves towards the first limiting part 401. When the third limiting part 701 comes into contact with the first limiting part 401, it prevents the rotating shaft 101 from continuing to rotate relative to the connecting member 4 in the first direction.

[0082] like Figure 10 As shown, when the rotating shaft 101 rotates relative to the connecting member 4 about the rotating shaft 5 in the first direction, the third limiting part 701 moves toward the line of defense close to the second limiting part 402. When the third limiting part 701 comes into contact with the second limiting part 402, it prevents the rotating shaft 101 from continuing to rotate relative to the connecting member 4 in the second direction.

[0083] By cooperating with the first limiting part 401 and the third limiting part 701, the minimum angle of rotation of the rotating shaft part 101 relative to the connecting member 4 can be limited, thereby preventing the spring 6 from excessively pushing the first housing 3 to rotate, so that the angle between the first housing 3 and the connecting member 4 is too small. In addition, the spring 6 can still be in a compressed state in the default state, thereby providing the initial clamping force for the headphones in the default state.

[0084] By cooperating with the second limiting part 402 and the third limiting part 701, the maximum angle of rotation of the rotating shaft part 101 relative to the connecting member 4 can be limited, thereby preventing excessive deformation of the spring 6 and improving the service life of the spring 6.

[0085] In some embodiments, such as Figure 9 and Figure 10 As shown, the third limiting part 701 can extend along the first plane, which can be parallel to the radial direction of the rotation shaft 5. During the rotation of the rotating part relative to the end of the connecting member 4, the extension direction of the third limiting part 701 can always point towards the rotation shaft 5. This allows the resistance received by the third limiting part 701 when it comes into contact with the first limiting part 401 or the second limiting part 402 to be opposite to the tangential direction of the rotation direction, thereby improving the limiting effect of the first limiting part 401 and the second limiting part 402 on the third limiting part 701. Furthermore, ensuring that the extension direction of the third limiting part 701 always points towards the rotation shaft 5 also reduces the rotation space required for the third limiting part 701.

[0086] In some embodiments, such as Figure 3 , Figure 9 and Figure 10As shown, the end of the connector 4 can be provided with a through hole 43, and the second elastic arm 62 can be inserted through the through hole 43. By inserting the second elastic arm 62 through the through hole 43, the position of the second elastic arm 62 can be fixed when the first elastic arm 61 rotates relative to the second elastic arm 62, thereby realizing the rotation of the first elastic arm 61 relative to the second elastic arm 62 to compress the spring body 60.

[0087] However, this disclosure is not limited to this. The second elastic arm 62 can also be fixed to the end of the connector 4 by other fixing methods. The fixing method can be any fixing method that can fix the second elastic arm 62 when the first elastic arm 61 rotates relative to the second elastic arm 62.

[0088] In some embodiments, such as Figure 3 , Figure 9 and Figure 10 As shown, the through hole 43 can be set in the second limiting part 402, thereby improving the compactness of the layout, increasing the utilization rate of components and the utilization rate of installation space, and reducing the design difficulty of the headphone space layout.

[0089] In some embodiments, such as Figure 6 As shown, the battery 10 can be a cylinder, and the first edge 103 can be an arc-shaped edge that matches the cylindrical arc surface of the battery 10.

[0090] The cylindrical battery 10 makes it easier to achieve a compact layout and improve volume utilization. Furthermore, the cylindrical battery 10 can increase the effective contact area of ​​the electrodes, thereby achieving higher energy storage in the same volume.

[0091] By configuring the first edge 103 as an arc-shaped edge that matches the cylindrical arc surface of the battery 10, the bracket 1 and the battery 10 can be arranged in a compact layout, thereby improving the space utilization of the bracket 1 and the battery 10, reducing the installation space required for the bracket 1 and the battery 10, thus providing more installation space for the headphones and reducing the design difficulty of the headphone space layout.

[0092] In some embodiments, such as Figures 4 to 6 As shown, the bracket 1 also includes a fixing part 102, which is fixedly connected to the rotating shaft part 101.

[0093] The fixing part 102 may include a first connecting part 121, which can be fixedly connected to the first housing 3. Through the fixed connection between the first connecting part 121 of the fixing part 102 and the first housing 3, the bracket 1 as a whole can be fixedly connected to the first housing 3.

[0094] The hardness of the fixing part 102 can be greater than that of the first housing 3. By configuring the hardness of the fixing part 102 to be higher, the fixing part 102 can withstand greater fixing pressure, thereby improving the connection stability between the fixing part 102 and the first housing 3 by increasing the fixing pressure.

[0095] This saves on additional fixing components, thereby reducing the space occupied by fixing the fixing part 102 and the first housing 3. For example, the fixing part 102 and the first housing 3 can be connected by only one screw.

[0096] In some embodiments, such as Figure 4 and Figure 5 The fixing part 102 and the rotating part 101 can be integrally molded, which can save the connecting parts used to fix the fixing part 102 and the rotating part 101, thereby further reducing the volume of the bracket 1 formed by the fixing part 102 and the rotating part 101, reducing the installation space required for the bracket 1, thus providing more installation space for the headphones and reducing the design difficulty of the headphone space layout.

[0097] In some embodiments, when the hardness of the first housing 3 is high, the hardness of the fixing part 102 may also be the same as the hardness of the first housing 3.

[0098] Figure 11 This is a cross-sectional structural schematic diagram of an earphone according to some embodiments of the present disclosure.

[0099] In some embodiments, such as Figure 4 , Figure 5 and Figure 11 As shown, the fixing part 102 may further include a second connecting part 122, and the earphone may include a circuit board 14, which is fixedly connected to the second connecting part 122. Fixing the circuit board 14 to the first housing 3 via the fixing part 102 can reduce the number of fixing connection parts between the circuit board 14 and the first housing 3.

[0100] Furthermore, since the fixing part 102 has high hardness, it can withstand greater fixing pressure, thereby improving the connection stability between the fixing part 102 and the circuit board 14 by increasing the fixing pressure.

[0101] The second connecting portion 122 can be disposed adjacent to the first connecting portion 121, thereby making the first connecting portion 121 and the second connecting portion 122 compactly arranged, thereby reducing the space volume required for the first connecting portion 121 and the second connecting portion 122.

[0102] In some embodiments, such as Figure 6As shown, the connection between the first connecting part 121 and the first housing 3 can be a screw connection. The earphone may include a first fixing member 8. The first connecting part 121 and the first housing 3 are respectively provided with screw holes. The first fixing member 8 can be disposed in the screw holes and fasten the first connecting part 121 and the first housing 3. The first connecting part 121 and the first housing 3 are fixed by screw connection, which facilitates subsequent installation, disassembly and maintenance. Moreover, the screw and the thread can provide high tensile and shear strength, thereby improving the connection stability of the first connecting part 121 and the first housing 3.

[0103] In some embodiments, the connection between the first connecting portion 121 and the first housing 3 can be an adhesive connection. Fixing the first connecting portion 121 and the first housing 3 by adhesive connection can reduce the damage to the first connecting portion 121 and the first housing 3 caused by machining, and the adhesive connection has a uniform stress distribution, which can reduce stress concentration in a certain part of the first connecting portion 121 and improve the service life of the first connecting portion 121.

[0104] In some embodiments, the connection between the first connecting part 121 and the first housing 3 can be a welding connection. Connecting the first connecting part 121 and the first housing 3 by welding can improve the connection strength between the first connecting part 121 and the first housing 3, and eliminates the need for additional fasteners, thereby reducing assembly steps and connecting components, and reducing the space required to connect the first connecting part 121 and the first housing 3.

[0105] In some embodiments, the connection between the first connecting part 121 and the first housing 3 can be a snap-fit ​​connection. Since snap-fit ​​connections have a faster assembly speed, they can improve the assembly efficiency of the production line and support non-destructive disassembly, facilitating the disassembly and repair of the headphones later.

[0106] In some embodiments, the connection method between the first connecting part 121 and the first housing 3 may include a variety of screw connection, adhesive connection, welding connection and snap-fit ​​connection.

[0107] In some embodiments, such as Figure 11 As shown, the second connecting part 122 and the circuit board 14 can be connected by screws. The earphone may include a second fixing member 9. The second connecting part 122 and the circuit board 14 are respectively provided with screw holes. The second fixing member 9 can be disposed in the screw holes and fasten the second connecting part 122 and the circuit board 14. The second connecting part 122 and the circuit board 14 are fixed by screw connection, which facilitates subsequent installation, disassembly and maintenance. Moreover, the screws and threads can provide high tensile and shear strength, thereby improving the connection stability between the second connecting part 122 and the circuit board 14.

[0108] In some embodiments, the connection between the second connecting portion 122 and the circuit board 14 can be an adhesive connection. Fixing the second connecting portion 122 and the circuit board 14 by adhesive connection can reduce damage to the second connecting portion 122 and the circuit board 14 caused by machining, and the adhesive connection has a uniform stress distribution, which can reduce stress concentration in a certain part of the second connecting portion 122 and improve the service life of the second connecting portion 122.

[0109] In some embodiments, the second connecting part 122 and the circuit board 14 can be connected by welding. Connecting the second connecting part 122 and the circuit board 14 by welding can improve the connection strength between the second connecting part 122 and the circuit board 14, and eliminates the need for additional fasteners, thereby reducing assembly steps and connecting components, and reducing the space required to connect the second connecting part 122 and the circuit board 14.

[0110] In some embodiments, the second connecting part 122 can be connected to the circuit board 14 via a snap-fit ​​connection. Since snap-fit ​​connections allow for faster assembly, they can improve assembly line efficiency and support non-destructive disassembly, facilitating later disassembly and repair of the headphones.

[0111] In some embodiments, the connection method between the second connecting part 122 and the circuit board 14 may include one or more of screw connection, adhesive connection, welding connection and snap connection.

[0112] In some embodiments, the fixing part 102 may be provided with a positioning post, one end of which can pass through the circuit board 14, thereby further improving the connection stability and accuracy between the circuit board 14 and the fixing part 102, and thus reducing the number of connecting parts used to fix the circuit board 14 and reducing the space required to fix the circuit board 14.

[0113] In some embodiments, the bracket 1 can be a metal part or a ceramic part. By configuring the bracket 1 as a metal part or a ceramic part, the bracket 1 can have higher hardness and strength, thereby being able to withstand greater fixing pressure. This allows for an increase in the fixing pressure to improve the connection stability between the bracket 1 and other components, thereby saving additional connecting parts and reducing the space volume required for connecting parts. Furthermore, since metal and ceramic parts have good durability, configuring the bracket 1 as a metal part or a ceramic part can also improve the service life of the bracket 1.

[0114] When at least a portion of the bracket 1 is exposed on the outer surface of the earphone, the bracket 1, being a metal or ceramic component, can enhance the texture and feel of the earphone's outer surface and improve its aesthetics.

[0115] However, this disclosure is not limited to this, and the support 1 can also be other components with higher hardness and strength.

[0116] In some embodiments, the connector 4 can also be a metal or ceramic component. The first housing 3 and the second housing can also be metal or ceramic components. This improves the texture and feel of the earphone's appearance, enhancing its aesthetic appeal.

[0117] This disclosure provides a receiving groove 100 in the rotating shaft portion 101 of the bracket 1, and sleeves the spring 6 on the rotating shaft 5 that passes through the receiving groove 100, thereby reducing the installation space occupied by the spring 6. By matching the shape of the first edge 103 with the shape of the battery 10, the integrated design of the spring 6, the bracket 1 and the battery 10 is realized, reducing the total installation space of the spring 6, the bracket 1 and the battery 10, improving the space utilization of the housing, and realizing the rotational connection structure between the housing and the connector 4 with a smaller installation space.

[0118] This disclosure incorporates a rotatable, flexible mechanical rotating structure into a miniature product like an ear clip-on headphone. While both the connector 4 and the first housing 3 are rigid structures, this allows for efficient rotation. Furthermore, it keeps the headphone's structural strength, weight, and size within a comfortable range for user comfort. Because the flexible mechanical rotating structure is located inside the first housing 3, the first housing 3, the second housing 2, and the connector 4 can all be made of high-quality, rigid materials such as metal or ceramic, enhancing both the headphone's aesthetics and durability.
