[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0031] In the ear-hanging earphone, the power supply assembly and the electro-acoustic assembly are usually arranged in two earphone shells respectively. This separated design can balance the weight distribution of the earphone and reduce the pressure on the ear, but it needs to pass through the connecting wire in the ear hook to realize the electrical connection between the power supply assembly and the electro-acoustic assembly. The inventor finds that in the related art, the connecting wire is connected to the adapter plate of the power supply assembly by welding. Since the welding size on the adapter plate is small, the welding operation is difficult, which leads to low assembly efficiency of the connecting wire and the power supply assembly. Moreover, it is difficult to reach the specified position for the welding operation, which in turn easily causes the welding point to be distorted or uneven, thereby affecting the electro-acoustic performance and service life of the earphone.

[0032] Based on this, the present application provides an earphone, please refer to Figures 1-2 , the earphone 1 includes an earphone shell 10, an ear hook 20, a connecting wire 30 and a power supply assembly 40. As shown in Figure 2 and Figure 3 , the earphone shell 10 is internally provided with a mounting cavity 100, and the mounting cavity 100 can accommodate other elements of the earphone 1. The earphone shell 10 also has a mounting opening 110 in communication 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, and the connecting wire 30 extends into the mounting cavity 100 from the inside of the ear hook 20, so that the connecting terminal 31 is accommodated in the mounting cavity 100. Among them, the connecting wire 30 is electrically connected to the power supply assembly 40 through the connecting terminal 31, so that the assembly of the earphone 1 is more convenient and efficient.

[0033] Please continue to refer toFigure 3 The power supply assembly 40 is arranged in the mounting cavity 100, and the power supply assembly 40 includes an adapter plate 41, a connector 42, and a battery 43. The adapter plate 41 is arranged on one side of the battery 43 along the diameter direction X of the battery 43, and the plate surface of the adapter plate 41 is perpendicular to the diameter direction X of the battery 43. The connector 42 is located on the side of the adapter plate 41 away from the battery 43 and is mounted 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 diameter direction X of the battery 43. The arrangement positions of the adapter plate 41, the connector 42, and the battery 43 are planned to leave space for the connection structure between the connection wire 30 and the adapter plate 41.

[0034] In the embodiment, the connection terminal 31 is inserted into the connector 42 along a direction parallel to the plate surface of the adapter plate 41. Compared with welding connection, the plug-in connection does not require complex welding equipment, and the production process can be simplified. The plug-in connection of the connection terminal 31 and the connector 42 is simple and efficient in assembly, and has good connection reliability. It can be understood that the plug-in direction of the connection terminal 31 and the connector 42 is parallel to the plate surface of the adapter plate 41, and the two occupy a small space in the diameter direction of the battery 43, which helps to reduce the size of the earphone shell 10 in the diameter direction of the battery 43.

[0035] In some embodiments, the earphone shell 10 includes an upper shell 11 and a lower shell 12. The upper shell 11 is mounted on the lower shell 12, and the upper shell 11 and the lower shell 12 jointly enclose the mounting cavity 100, thereby facilitating the assembly of the power supply assembly 40 in the earphone shell 10.

[0036] In actual assembly, the upper shell 11 has a mounting opening 110. After the ear hook 20 is mounted on the upper shell 11, the connection terminal 31 extends into the upper shell 11 and can be inserted into the connector 42. Then, the adapter plate 41 is mounted on the upper shell 11, and the battery 43 is mounted on the lower shell 12, and the battery 43 remains electrically connected to the adapter plate 41. In this way, the connection wire 30 and the various elements of the power supply assembly 40 are pre-assembled in the upper shell 11 and the lower shell 12, respectively. Then, the upper shell 11 and the lower shell 12 are closed and fixed to complete the assembly of the power supply assembly 40, the connection wire 30, and the earphone shell 10. The assembly process is simple.

[0037] In some embodiments, the plug-in direction of the connection terminal 31 and the connector 42 is parallel to the plate surface of the adapter plate 41, which can provide more mounting space for other elements of the earphone 1. Figure 4 As shown, the power supply assembly 40 further includes an auxiliary microphone 44. The auxiliary microphone 44 is arranged in the mounting cavity 100, and the auxiliary microphone 44 is located on the side of the adapter plate 41 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, thereby improving the intelligibility of the earphone 1.

[0038] The auxiliary microphone 44 is detachably mounted on the upper shell 11, so as to facilitate the maintenance or replacement of the auxiliary microphone 44. Exemplarily, the auxiliary microphone 44 is adhesively connected to the inner wall of the upper shell 11, and the auxiliary microphone 44 is electrically connected to the adapter plate 41.

[0039] Referring to Figure 5 The upper shell 11 and the lower shell 12 are snap-fitted, wherein the upper shell 11 has a first mounting portion 111, the lower shell 12 has a second mounting portion 121, the first mounting portion 111 is inserted into the second mounting portion 121, and the first mounting portion 111 and the second mounting portion 121 are snap-fitted to ensure the stable connection of the upper shell 11 and the lower shell 12.

[0040] Exemplarily, one of the first mounting portion 111 and the second mounting portion 121 is provided with a snap-fitting protrusion 101 on the outer wall, and the other is provided with a snap-fitting groove 102 on the inner wall. After the first mounting portion 111 and the second mounting portion 121 are inserted and connected, the snap-fitting protrusion 101 is snap-fitted into the snap-fitting groove 102.

[0041] In some embodiments, in order to avoid the first mounting portion 111 and the second mounting portion 121 being unable to be smoothly snap-fitted due to circumferential misalignment, the first mounting portion 111 and the second mounting portion 121 are further provided with a limiting structure capable of ensuring the 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 extending to the end of the first mounting portion 111 along the diameter direction X of the battery 43, and 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 matched with each other to maintain the inserted 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 the assembly efficiency.

[0042] In some embodiments, the earphone 1 further comprises sealing glue, at least part of which is filled in the connection position of the upper shell 11 and the lower shell 12. The sealing glue plays a role of fixing and sealing, and can improve the mechanical strength of the connection position of the earphone shell 10 and ensure the waterproof performance of the connection position.

[0043] As Figures 5-6As shown, the upper shell 11 has a first mating surface 11a, and the lower shell 12 has a second mating surface 12a, both of which are perpendicular to the diameter direction X of the battery 43. After the first mounting portion 111 is snap-fitted with the second mounting portion 121, the first mating surface 11a and the second mating surface 12a are connected in abutment. At least part of the sealant is arranged between the first mating surface 11a and the second mating surface 12a, so as to seal the gap between the first mating surface 11a and the second mating surface 12a, to ensure normal use of the earphone 1 in a humid environment, and to improve the durability of the earphone 1.

[0044] In order to avoid the sealant overflowing from the earphone shell 10 and affecting the appearance flatness of the earphone 1, the sealant is filled on the side of the earphone shell 10 close to the mounting cavity 100. For example, if the first mounting portion 111 is inserted into the second mounting portion 121, the first mating surface 11a is arranged at the end of the first mounting portion 111, and the second mating surface 12a is arranged around the inner periphery of the second mounting portion 121, so as to ensure that the sealant arranged between the first mating surface 11a and the second mating surface 12a is located on the radial inner side of the second mounting portion 121. Correspondingly, if the second mounting portion 121 is inserted into the first mounting portion 111, the first mating surface 11a is arranged around the inner periphery of the first mounting portion 111, and the second mating surface 12a is arranged at the end of the second mounting portion 121.

[0045] In some embodiments, the upper shell 11 includes a third mounting portion 112 provided with a mounting opening 110. The ear hook 20 includes a fitting piece 21 inserted into the mounting opening 110, wherein the fitting piece 21 is snap-fitted with the third mounting portion 112, and the fitting piece 21 and the third mounting portion 112 are sealingly connected. In actual assembly, the fitting piece 21 at least partially extends into the third mounting portion 112, and the outer wall surface of the part is coated with sealant. The sealant can fill and seal the gap between the fitting piece 21 and the third mounting portion 112, to avoid water seepage at the connection position of the ear hook 20 and the upper shell 11.

[0046] In some embodiments, the fitting piece 21 includes a fitting base 211 and a clamping portion 212 extending from the end of the fitting base 211 towards the third mounting portion 112. The fitting base 211 is inserted into the mounting opening 110, and the clamping portion 212 penetrates the mounting opening 110 and is snap-fitted with the end of the third mounting portion 112 towards the mounting cavity 100.

[0047] The clamping portion 212 can be a tongue structure or a hook structure, and multiple clamping portions 212 can also be provided to improve the stability of the connection between the fitting piece 21 and the third mounting portion 112.

[0048] Further, the third mounting portion 112 is provided with a guide groove at an end away from the mounting cavity 100, a groove bottom wall of the guide groove is gradually inclined to an inner wall of the third mounting portion 112, in the assembly process of the fitting part 21 and the third mounting portion 112, the clamping part 212 is inserted into the guide groove and gradually penetrates into the mounting opening along the guide groove, under the action of the groove bottom wall, the clamping part 212 gradually elastically deforms until contacting the inner wall of the third mounting portion 112, thus helping to reduce the stroke of the elastic deformation of the clamping part 212, avoiding the elastic mutation of the clamping part 212, and reducing the probability of damage of the fitting part 21.

[0049] It can be understood that the ear hook 20 and the earphone shell 10 are usually connected at a fixed angle to enable the earphone 1 to be hung on the ear of the user, and therefore, the assembly of the ear hook 20 and the earphone shell 10 also needs to be circumferentially aligned. The third mounting portion 112 and the fitting part 21 can be circumferentially aligned through the cooperation of the guide groove and the clamping part 212, or the third mounting portion 112 and the fitting part 21 can be circumferentially aligned through the setting of a limiting structure.

[0050] In the above structure, the earphone 1 realizes the sealed connection between the ear hook 20 and the upper shell 11, and between the upper shell 11 and the lower shell 12 through the sealing glue, so that a relatively closed environment is formed inside the earphone shell 10, external moisture is blocked from penetrating, and the power supply assembly 40 is protected from water vapor. In other embodiments, the earphone 1 can also realize the sealing between the earphone shell 10 and the ear hook 20 through the setting of an elastic part, wherein the elastic part can adopt a rubber gasket, a sealing rubber ring, etc., for example, a sealing rubber ring is arranged at the connecting position of the upper shell 11 and the lower shell 12, the sealing rubber ring fills the gap between the upper shell 11 and the lower shell 12 through elastic deformation, and external moisture is blocked from penetrating.

[0051] In the embodiment of the present application, the ear hook 20 further includes a connecting shell 22, and the connecting shell 22 is made of an elastic material, wherein the connecting shell 22 can be made of a material such as silicone, fluorine rubber, etc. The fitting part 21 is arranged at an end of the connecting shell 22, and the connecting wire 30 is routed along the connecting shell 22 and passes through the connecting shell 22. The connecting shell 22 can maintain a certain shape and tension to enable the earphone 1 to be hung on the ear of the user.

[0052] In some embodiments, the ear hook 20 further includes a shaping part 23, which can be configured as a memory metal such as a titanium wire, a copper-zinc alloy wire, a copper-aluminum-nickel alloy wire, or a copper-gold-zinc alloy wire, etc., and the shaping part 23 is used to support the shape of the connecting shell 22 to prevent the connecting shell 22 from being deformed under stress.

[0053] In the power supply assembly 40, the adapter plate 41 is adhesively connected to the upper shell 11. The inner wall surface of the upper shell 11 includes a first step surface and a second step surface. The first step surface is parallel to the plate surface of the adapter plate 41. The second step surface is located on the side of the first step surface away from the mounting opening 110 and is connected to the first step surface perpendicularly. The adapter plate 41 is arranged on the side of the first step surface away from the mounting opening 110, and the adapter plate 41 is adhesively connected to at least one of the first step surface and the second step surface. The position stability of the adapter plate 41 after installation is ensured, and displacement that may occur during the assembly of the upper shell 11 and the lower shell 12 or during the use of the earphone 1 is effectively avoided, so that the plug connection of the connector 42 and the connecting terminal 31 is more stable and reliable.

[0054] In some embodiments, the adapter plate 41 is provided with at least one first positioning portion 411 around the circumference thereof, 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 plug-fitted to position the installation position of the adapter plate 41 relative to the circumference of the earphone shell 10, so as to avoid mispositioning of the adapter plate 41 affecting the installation of other elements.

[0055] In some embodiments, a wire passing opening is formed between the side wall surface of the adapter plate 41 and the inner wall surface of the earphone shell 10. The power supply assembly 40 further includes a flexible flat cable 45. One end of the flexible flat cable 45 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 flat cable has good flexibility and can be bent and folded in a small space, so as to well adapt to the installation environment in the earphone shell 10.

[0056] In the embodiments of the present application, the earphone 1 further includes an electro-acoustic assembly 50. The earphone 1 includes two earphone shells 10, and the two ends of the ear hook 20 are respectively provided with one earphone shell 10. One of the earphone shells 10 is used to install the electro-acoustic assembly 50, which can have a main microphone and a loudspeaker structure. The electro-acoustic assembly 50 is used to transmit sound to the ear of a user. The other earphone shell 10 is used to install the power supply assembly 40. The electro-acoustic assembly 50 and the power supply assembly 40 are electrically connected through the connecting lead 30, so that the power supply assembly 40 can supply power to the electro-acoustic assembly 50.

[0057] Optionally, the two ends of the connecting lead 30 are provided with connecting terminals 31. One end of the connecting lead 30 is plug-connected to the power supply assembly 40 through one connecting terminal 31, and the other end is plug-connected to the electro-acoustic assembly 50 through another connecting terminal 31. This helps to improve the overall assembly efficiency of the earphone 1 and ensure the transmission stability of the electro-acoustic assembly 50 and the power supply assembly 40.

[0058] In some embodiments, the earphone 1 further comprises a plurality of first magnetic members 60, wherein part of the first magnetic members 60 are arranged in the same earphone shell 10 as the power supply assembly 40, and the other part of the first magnetic members 60 are arranged in the same earphone shell 10 as the electro-acoustic assembly 50. The first magnetic members 60 are used to be magnetically attracted to the second magnetic members in the earphone box to fix the earphone 1 relative to the earphone box when the earphone 1 is placed in the earphone box for charging, thereby reducing the risk of moving and knocking.
