[0003] In headphone design, to improve wearing comfort and optimize acoustic effects, the power supply component and the electroacoustic component are usually placed in two separate headphone shells, connected by ear hooks, and a connecting wire is installed inside the ear hooks to achieve electrical connection between the power supply component and the electroacoustic component.

[0004] In related technologies, the available space inside the earphone shell is limited, and the battery volume of the power supply component is relatively large, resulting in limited space for the placement of other components within the power supply component. Similarly, the speaker volume of the electroacoustic component is relatively large, further limiting the space for the placement of other components within the electroacoustic component. Therefore, one end of the connecting wire is typically soldered to the power supply component, and the other end is also typically soldered to the electroacoustic component. However, due to the limited size of the components, the soldering space at both ends of the connecting wire is limited, leading to significant assembly difficulties between the connecting wire and the power supply component, and between the connecting wire and the electroacoustic component, resulting in assembly efficiency that needs improvement.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] In ear-hook headphones, the power supply and electroacoustic components are typically housed in separate earphone shells. While this separate design balances the weight distribution and reduces ear pressure, it requires connecting wires within the ear hooks to establish an electrical connection between the power supply and electroacoustic components. The inventors discovered that in related technologies, the connecting wires are soldered to an adapter plate on the power supply component. However, the small solder joint size on the adapter plate makes soldering difficult, resulting in low assembly efficiency between the connecting wires and the power supply component. Furthermore, the soldering operation is difficult to achieve at specific locations, easily leading to twisted or uneven solder joints, which in turn affects the headphone's electroacoustic performance and lifespan.

[0021] Based on this, this application provides an earphone, please refer to... Figures 1-2 The earphone 1 includes an earphone shell 10, an ear hook 20, a connecting cable 30, and a power supply assembly 40. For example... Figure 2 and Figure 3 As shown, the earphone shell 10 has a mounting cavity 100 inside, which can accommodate other components of the earphone 1. The earphone shell 10 also has a mounting opening 110 communicating with the mounting cavity 100. The ear hook 20 is mounted on the earphone shell 10 corresponding to the mounting opening 110. The connecting wire 30 includes a connecting terminal 31. The connecting wire 30 extends from the inside of the ear hook 20 into the mounting cavity 100 so that the connecting terminal 31 is accommodated in the mounting cavity 100. The connecting wire 30 is electrically connected to the power supply assembly 40 through the connecting terminal 31, making the assembly of the earphone 1 simpler and more efficient.

[0022] Please continue reading. Figure 3 The power assembly 40 is located in the mounting cavity 100. The power assembly 40 includes an adapter plate 41, a connector 42, and a battery 43. The adapter plate 41 is located on one side of the battery 43 along the height direction X, and the plate surface of the adapter plate 41 is perpendicular to the height direction X of the battery 43. The connector 42 is located on the side of the adapter plate 41 facing away from the battery 43 and is installed on the adapter plate 41. That is, the battery 43, the adapter plate 41, and the connector 42 are arranged side by side along the height direction X of the battery 43. By planning the arrangement of the adapter plate 41, the connector 42, and the battery 43, space is left for the connection structure between the connecting wire 30 and the adapter plate 41.

[0023] In this embodiment, the connecting terminal 31 is inserted into the connector 42 along a direction parallel to the surface of the adapter plate 41. Compared to welding, the plug-in connection eliminates the need for complex welding equipment, simplifying the production process. The assembly of the plug-in connection between the connecting terminal 31 and the connector 42 is simple, efficient, and reliable. It is understood that the insertion direction of the connecting terminal 31 and the connector 42 is parallel to the surface of the adapter plate 41, resulting in a small space occupation in the height direction of the battery 43, which helps to reduce the size of the earphone shell 10 in the height direction of the battery 43.

[0024] In some embodiments, the earphone shell 10 includes an upper shell 11 and a lower shell 12, with the upper shell 11 mounted on the lower shell 12, and the upper shell 11 and the lower shell 12 together forming a mounting cavity 100, thereby facilitating the assembly of the power supply assembly 40 into the earphone shell 10.

[0025] In actual assembly, the upper housing 11 has an installation opening 110. After the ear hook 20 is installed on the upper housing 11, the connecting terminal 31 extends into the upper housing 11 and can be plugged into the connector 42. Then, the adapter plate 41 is installed on the upper housing 11, and the battery 43 is installed on the lower housing 12, with the battery 43 maintaining an electrical connection to the adapter plate 41. In this way, the connecting wires 30 and the various components of the power assembly 40 are pre-assembled on the upper housing 11 and the lower housing 12 respectively, and then the upper housing 11 and the lower housing 12 are closed and fixed to complete the assembly of the power assembly 40, the connecting wires 30, and the earphone shell 10. The assembly process is simple.

[0026] In some embodiments, the insertion direction of the connecting terminal 31 and the connector 42 is parallel to the surface of the adapter plate 41, which provides more installation space for other components of the earphone 1. For example... Figure 4As shown, the power supply assembly 40 also includes an auxiliary microphone 44, which is disposed in the mounting cavity 100 and located on the side of the adapter plate 41 facing away from the battery 43. The earphone 1 is also provided with a main microphone. Based on the sound captured by the main microphone and the ambient noise captured by the auxiliary microphone 44, the ambient noise in the sound is filtered through an algorithm to improve the clarity of the earphone 1.

[0027] The auxiliary microphone 44 is detachably mounted on the upper housing 11 to facilitate maintenance or replacement. For example, the auxiliary microphone 44 is adhesively attached to the inner wall of the upper housing 11 and electrically connected to the adapter plate 41.

[0028] Please see Figure 5 The upper housing 11 and the lower housing 12 are snap-fitted together. The upper housing 11 has a first mounting part 111 and the lower housing 12 has a second mounting part 121. The first mounting part 111 is inserted into the second mounting part 121, and the first mounting part 111 and the second mounting part 121 are snap-fitted together to ensure a stable connection between the upper housing 11 and the lower housing 12.

[0029] For example, one of the first mounting part 111 and the second mounting part 121 has a snap-fit ​​protrusion 101 on its outer wall and a snap-fit ​​groove 102 on its inner wall. After the first mounting part 111 and the second mounting part 121 are connected by insertion, the snap-fit ​​protrusion 101 snaps into the snap-fit ​​groove 102.

[0030] In some embodiments, to prevent the first mounting portion 111 and the second mounting portion 121 from failing to engage smoothly due to circumferential misalignment, the first mounting portion 111 and the second mounting portion 121 are also provided with limiting structures. The limiting structures can ensure accurate alignment of the first mounting portion 111 and the second mounting portion 121. The outer wall surface of the first mounting portion 111 is provided with a first limiting groove 103, and the first limiting groove 103 extends along the height direction X of the battery 43 to the end of the first mounting portion 111. The inner wall surface of the second mounting portion 121 is provided with a first limiting protrusion 104. During the assembly of the earphone shell 10, the first limiting groove 103 and the first limiting protrusion 104 are aligned and cooperate with each other to maintain the insertion state, thereby limiting the relative movement of the first mounting portion 111 and the second mounting portion 121 in the circumferential direction, reducing the risk of assembly misalignment, and helping to improve assembly efficiency.

[0031] In some embodiments, the earphone 1 further includes a sealant, at least a portion of which fills the connection between the upper housing 11 and the lower housing 12. The sealant serves to fix and seal, thereby improving the mechanical strength of the connection point of the earphone housing 10 and ensuring the waterproof performance of the connection point.

[0032] like Figures 5-6As shown, the upper housing 11 has a first mating surface 11a, and the lower housing 12 has a second mating surface 12a. Both the first mating surface 11a and the second mating surface 12a are perpendicular to the height direction X of the battery 43. After the first mounting part 111 and the second mounting part 121 are engaged, the first mating surface 11a and the second mating surface 12a are fitted together. At least a portion of the sealant is disposed between the first mating surface 11a and the second mating surface 12a to seal the gap between the first mating surface 11a and the second mating surface 12a, ensuring the normal use of the earphone 1 in a humid environment and improving the durability of the earphone 1.

[0033] To prevent sealant from overflowing from the earphone shell 10 and affecting the flatness of the earphone 1, sealant is filled on the side of the earphone shell 10 near the mounting cavity 100. For example, if the first mounting part 111 is inserted into the second mounting part 121, the first mating surface 11a is located at the end of the first mounting part 111, and the second mating surface 12a is arranged around the inner periphery of the second mounting part 121, thereby ensuring that the sealant disposed between the first mating surface 11a and the second mating surface 12a is located radially inward of the second mounting part 121. Correspondingly, if the second mounting part 121 is inserted into the first mounting part 111, the first mating surface 11a is arranged around the inner periphery of the first mounting part 111, and the second mating surface 12a is located at the end of the second mounting part 121.

[0034] In some embodiments, the upper housing 11 includes a third mounting portion 112, which has a mounting opening 110. The ear hook 20 includes a mating member 21, which is inserted into the mounting opening 110. The mating member 21 engages with the third mounting portion 112, and a sealed connection is established between the mating member 21 and the third mounting portion 112. In actual assembly, the mating member 21 extends at least partially into the third mounting portion 112, and the outer wall surface of this portion is coated with sealant. The sealant fills and seals the gap between the mating member 21 and the third mounting portion 112, preventing water leakage at the connection point between the ear hook 20 and the upper housing 11.

[0035] In some embodiments, the mating member 21 includes a mating base 211 and a locking portion 212, the locking portion 212 extending from the end of the mating base 211 toward the third mounting portion 112. The mating base 211 is inserted into the mounting opening 110, and the locking portion 212 passes through the mounting opening 110 and engages with the end of the third mounting portion 112 toward the mounting cavity 100.

[0036] The engaging part 212 can be a tongue-shaped structure or a hook-shaped structure, etc. In addition, multiple engaging parts 212 can be provided to improve the stability of the connection between the mating part 21 and the third mounting part 112 by multi-point positioning.

[0037] Furthermore, the third mounting part 112 is provided with a guide groove at one end away from the mounting cavity 100. The bottom wall of the guide groove gradually slopes towards the inner wall of the third mounting part 112. During the assembly of the mating part 21 and the third mounting part 112, the engaging part 212 is inserted into the guide groove and gradually penetrates into the mounting opening along the guide groove. Under the action of the bottom wall of the groove, the engaging part 212 gradually undergoes elastic deformation until it contacts the inner wall of the third mounting part 112. This helps to reduce the travel of the elastic deformation of the engaging part 212, avoids the engaging part 212 from undergoing abrupt elastic changes, and reduces the probability of damage to the mating part 21.

[0038] It is understandable that the ear hook 20 and the earphone shell 10 are usually connected at a fixed angle so that the earphone 1 can be held on the user's ear. Therefore, the assembly of the ear hook 20 and the earphone shell 10 also requires circumferential alignment. The third mounting part 112 and the mating part 21 can achieve circumferential alignment through the cooperation of the guide groove and the engaging part 212, or the third mounting part 112 and the mating part 21 can achieve circumferential alignment by setting a limiting structure.

[0039] In the above structure, the earphone 1 achieves a sealed connection between the ear hook 20 and the upper shell 11, and between the upper shell 11 and the lower shell 12, through sealant. This creates a relatively closed environment inside the earphone shell 10, preventing the infiltration of external moisture and thus protecting the power supply component 40 from moisture damage. In other embodiments, the earphone 1 can also achieve a seal inside the earphone shell 10 and between the earphone shell 10 and the ear hook 20 by setting elastic elements. The elastic elements can be rubber gaskets, sealing rings, etc. For example, a sealing ring can be set at the connection position between the upper shell 11 and the lower shell 12. The sealing ring fills the gap between the upper shell 11 and the lower shell 12 through elastic deformation, preventing the infiltration of external moisture.

[0040] In this embodiment, the ear hook 20 further includes a connecting shell 22, which is made of an elastic material, such as silicone or fluororubber. A mating part 21 is located at the end of the connecting shell 22, and a connecting wire 30 runs along and passes through the connecting shell 22. The connecting shell 22 maintains a certain shape and tension to allow the earphone 1 to be held in place by the user's ear.

[0041] In some embodiments, the ear hook 20 further includes a shaping element 23, which can be configured as a shape memory metal, such as titanium wire, copper-zinc alloy wire, copper-aluminum-nickel alloy wire, or copper-gold-zinc alloy wire. The shaping element 23 is used to support the shape of the connecting shell 22 and prevent the connecting shell 22 from deforming under force.

[0042] In the power supply assembly 40, an adapter plate 41 is bonded to the upper housing 11. The inner wall surface of the upper housing 11 includes a first stepped surface and a second stepped surface. The first stepped surface is parallel to the surface of the adapter plate 41, and the second stepped surface is located on the side of the first stepped surface facing away from the mounting opening 110 and is perpendicularly connected to the first stepped surface. The adapter plate 41 is located on the side of the first stepped surface facing away from the mounting opening, and is bonded to at least one of the first and second stepped surfaces. This ensures the positional stability of the adapter plate 41 after installation, effectively preventing displacement that may occur during the assembly of the upper housing 11 and lower housing 12 or during the use of the earphone 1, making the insertion of the connector 42 and the connecting terminal 31 more stable and reliable.

[0043] In some embodiments, the adapter plate 41 is provided with at least one first positioning portion 411 around its circumference, and the earphone shell 10 has at least one second positioning portion 113. One of the first positioning portion 411 and the second positioning portion 113 is a positioning protrusion and the other is a positioning groove. The positioning protrusion and the positioning groove are interlocked to position the adapter plate 41 relative to the circumferential mounting position of the earphone shell 10, so as to avoid misalignment of the adapter plate 41 affecting the installation of other components.

[0044] In some embodiments, a wire-passing opening is formed between the sidewall of the adapter plate 41 and the inner wall of the earphone shell 10. The power assembly 40 also includes a flexible ribbon cable 45, one end of which is electrically connected to the adapter plate 41, and the other end passes through the wire-passing opening and is electrically connected to the battery 43. The flexible ribbon cable has good flexibility and can be bent and folded in a confined space, thus adapting well to the installation environment inside the earphone shell 10.

[0045] In this embodiment, the earphone 1 further includes an electroacoustic component 50. The earphone 1 includes two earphone shells 10, with one earphone shell 10 installed at each end of the ear hook 20. One earphone shell 10 is used to house the electroacoustic component 50, which may have a main microphone and speaker structure. The electroacoustic component 50 is used to transmit sound to the user's ear. The other earphone shell 10 is used to house a power supply component 40. The electroacoustic component 50 and the power supply component 40 are electrically connected via a connecting wire 30, so that the power supply component 40 can supply power to the electroacoustic component 50.

[0046] Optionally, both ends of the connecting wire 30 are provided with connecting terminals 31. One end of the connecting wire 30 is connected to the power supply component 40 through one connecting terminal 31, and the other end is connected to the electroacoustic component 50 through another connecting terminal 31. This helps to improve the overall assembly efficiency of the headphones 1 and ensure the transmission stability of the electroacoustic component 50 and the power supply component 40. In some embodiments, the earphone 1 further includes a plurality of first magnetic components 60, wherein some of the first magnetic components 60 and the power component 40 are disposed in the same earphone shell 10, and other parts of the first magnetic components 60 and the electroacoustic component 50 are disposed in the same earphone shell 10. The first magnetic components 60 are used to magnetically engage with the second magnetic components inside the earphone case, so that the earphone 1 can be fixed relative to the earphone case when it is placed inside the earphone case for charging, thereby reducing the risk of movement and bumps.
