Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown, this application embodiment provides an earphone head module 1, which includes an earphone head body 11 and a first electrical connection mechanism 12 disposed on the earphone head body 11. The earphone head body 11 contains a plurality of functional elements. The first electrical connection mechanism 12 includes a plurality of first interfaces 121 connected to the functional elements. The plurality of first interfaces 121 are adapted to be electrically connected to the earphone accessory 2, so that the plurality of functional elements are electrically connected to the earphone accessory 2.

[0037] For example, the functional elements include components such as speakers, microphones, and sensors, which can realize functions such as frequency division sound effects, wear detection, and active noise cancellation.

[0038] The headphone module 1 is used in the headphone assembly, which includes headphone accessories 2. Both the headphone module 1 and the headphone accessories 2 are independent modules. The headphone module 1 can be electrically connected to different types of headphone accessories 2 through the first interface 121, thereby forming headphone assemblies of different shapes to meet the different usage needs of users.

[0039] For example Figure 2 , Figure 4 and Figure 6 As shown, the headphone accessory 2 can be a wired accessory, an ear hook accessory, a stem-shaped accessory, etc. The headphone head module 1 and the headphone accessory 2 can be connected to form a complete unit. Figure 3 The wired headphones shown Figure 5 The ear-hook headphones shown Figure 7 The various types of headphone components shown, such as the rod-shaped earphones, allow for adaptability to different usage scenarios. It is understandable that... Figure 2 and Figure 3 Only a portion of the headphone accessory 2 cable is shown.

[0040] Specifically, the headphone accessory 2 includes a second electrical connection mechanism 21 adapted to the first electrical connection mechanism 12. The second electrical connection mechanism 21 includes a plurality of second interfaces 211, and the plurality of first interfaces 121 and the plurality of second interfaces 211 are electrically connected in a one-to-one correspondence to realize the cooperative connection between the headphone module 1 and the headphone accessory 2.

[0041] The number of functional elements and the first interface 121 are both at least two, for example Figure 1 As shown, the number of first interfaces 121 is eight. Compared with the related technology, which uses MMCX (Micro-Miniature Coaxial) connectors for electrical connection and can only provide a maximum of 2-pin electrical connection, the headphone module 1 provided in this application embodiment expands the number of interfaces between itself and the headphone accessory 2, increases the electrical connection channel between itself and the headphone accessory 2, and allows more functional components to be placed in the headphone module 1, thereby enabling the headphone module 1 and the headphone assembly to achieve more functions.

[0042] The earphone head module 1 provided by the embodiment of the present application is provided with the first electric connection mechanism 12 including the first interface 121 connected with the functional element, so that the functional element of the earphone head module 1 can be electrically connected with different earphone accessories 2 through the first interface 121, thereby forming different forms of earphone assemblies, and further making the earphone assemblies applicable to various working scenarios and meeting the diversified use requirements of users, which helps to improve the use experience of users; by providing a plurality of first interfaces 121, the number of interfaces between the earphone head module 1 and the earphone accessories 2 is expanded, the electric connection channel between the earphone head module 1 and the earphone accessories 2 is increased, and more functional elements can be placed in the earphone head module 1, thereby making the earphone head module 1 and the earphone assembly be able to realize more functions.

[0043] In one specific embodiment, the plurality of first interfaces 121 are conductive sheets 121a and / or stretchable conductive elastic pins 121b.

[0044] For example, as shown in Figure 1 , the plurality of first interfaces 121 are all conductive sheets 121a; or, the plurality of first interfaces 121 are all stretchable conductive elastic pins 121b; or, part of the first interfaces 121 are conductive sheets 121a, and the other part of the first interfaces 121 are stretchable conductive elastic pins 121b.

[0045] In the case that at least part of the first interfaces 121 are stretchable conductive elastic pins 121b, the first interface 121 can improve the reliability and fault tolerance of the electrical connection between itself and the earphone accessory 2, and in the case that the cooperation gap between the earphone head module 1 and different earphone accessories 2 is different, the first interface 121 can ensure the reliable connection between the earphone head module 1 and each kind of earphone accessory 2 through the adaptive stretching of itself; in the case that at least part of the first interfaces 121 are conductive sheets 121a, it is helpful to improve the contact area between the first interface 121 and the second interface 211, so that the connection between the first interface 121 and the second interface 211 is more stable.

[0046] For example, as shown in Figure 1 and Figure 2 , in the case that the plurality of first interfaces 121 are all conductive sheets 121a, the plurality of second interfaces 211 are all stretchable conductive elastic pins 121b.

[0047] In one embodiment, the first electric connection mechanism 12 further includes a first auxiliary connection structure 122, and the first auxiliary connection structure 122 is adapted to be detachably connected with the earphone accessory 2.

[0048] For example, the earphone accessory 2 includes a second auxiliary connection structure 212, and the second auxiliary connection structure 212 is used for detachable connection with the first auxiliary connection structure 122.

[0049] Exemplarily, the first auxiliary connecting structure 122 is detachably connected with the earphone accessory 2 through snap connection, pin connection, magnetic connection, threaded connection, etc.

[0050] By arranging the first auxiliary connecting structure 122, the connection strength between the earphone head module 1 and the earphone accessory 2 is strengthened, and the connection reliability and stability are improved. The first auxiliary connecting structure 122 is detachably connected with the earphone accessory 2, which facilitates the user to quickly connect or separate the earphone head module 1 and the earphone accessory 2, and improves the disassembly efficiency of the earphone assembly.

[0051] In one specific embodiment, the first auxiliary connecting structure 122 is a magnetic piece.

[0052] Correspondingly, the second auxiliary connecting structure 212 of the earphone accessory 2 is also a magnetic piece. The earphone head module 1 and the earphone accessory 2 are magnetically attracted through the magnetic attraction between the first auxiliary connecting structure 122 and the second auxiliary connecting structure 212, which improves the connection reliability and stability of the earphone head module 1 and the earphone accessory 2, and facilitates the replacement of the earphone accessory 2 connected with the earphone head module 1.

[0053] Further, as shown in Figure 1 , the first auxiliary connecting structure 122 is in a strip shape, and the two ends of the first auxiliary connecting structure 122 in the length direction are different magnetic poles.

[0054] Correspondingly, as shown in Figure 2 , Figure 4 or Figure 6 , the second auxiliary connecting structure 212 is in a strip shape, and the two ends of the second auxiliary connecting structure 212 in the length direction are different magnetic poles.

[0055] Through the above arrangement, the earphone head module 1 has a self-alignment function. When the first auxiliary connecting structure 122 and the earphone accessory 2 approach each other, they will automatically align to the correct connection position, ensuring that the earphone head module 1 and the earphone accessory 2 are connected in the correct direction, so that the functional elements are accurately electrically connected with the earphone accessory 2, which helps to improve the installation error-proofing of the earphone head module 1.

[0056] In one embodiment, the plurality of first interfaces 121 are asymmetrically distributed.

[0057] Exemplarily, the plurality of first interfaces 121 are mounted on the first end surface 123 of the first electrical connection mechanism 12, and the plurality of first interfaces 121 are asymmetrically distributed on the first end surface 123, for example, the number of the first interfaces 121 on the first side of the first end surface 123 is different from the number of the first interfaces 121 on the second side. It can be understood that the plurality of second interfaces 211 are distributed in the same manner as the plurality of first interfaces 121, and the plurality of second interfaces 211 are also asymmetrically distributed, so as to ensure that the plurality of first interfaces 121 and the plurality of second interfaces 211 are connected one by one.

[0058] Through the arrangement, the foolproofness of the earphone head module 1 is improved, the user is facilitated to identify the correct installation direction of the earphone head module 1 and the earphone accessory 2, and the connection mistake prevention of the earphone head module 1 and the earphone accessory 2 is improved.

[0059] In an optional embodiment, the at least two first interfaces 121 have different external features, and the external features include one or more of color, shape, size, and texture.

[0060] Exemplarily, each second interface 211 has the same external feature as the corresponding first interface 121.

[0061] Through the arrangement that the at least two first interfaces 121 have different external features, the foolproofness of the earphone head module 1 is improved, the user is facilitated to identify the correct installation direction of the earphone head module 1 and the earphone accessory 2, and the connection mistake prevention of the earphone head module 1 and the earphone accessory 2 is improved.

[0062] As shown in Figures 2 to 7 , the embodiment of the present application also provides an earphone assembly, which comprises the earphone accessory 2 and the earphone head module 1 provided by any of the above embodiments, and the earphone accessory 2 comprises the second electrical connection mechanism 21, and the second electrical connection mechanism 21 comprises the plurality of second interfaces 211, which are electrically connected one by one with the plurality of first interfaces 121.

[0063] For example Figure 2 , Figure 4 and Figure 6 , the earphone accessory 2 can be a wired accessory, an ear-hanging accessory, a rod-shaped accessory, etc., and the earphone head module 1 and the earphone accessory 2 are connected in cooperation to form various types of earphone assemblies such as a wired earphone as shown in Figure 3 , an ear-hanging earphone as shown in Figure 5 , a rod-shaped earphone as shown in Figure 7 , etc., so that the earphone assembly is applicable to different use scenarios. It can be understood that Figure 2 and Figure 3 only a part of the cable of the earphone accessory 2 is shown.

[0064] The earphone assembly provided by the embodiments of the present application is characterized in that the first electric connection mechanism 12 of the earphone head module 1 comprises a first interface 121 connected with a functional element, so that the functional element of the earphone head module 1 can be electrically connected with different earphone accessories 2 through the first interface 121, thereby forming different forms of earphone assemblies, and further making the earphone assemblies applicable to various working scenarios and meeting the diversified use requirements of users, which helps to improve the use experience of users; by arranging a plurality of first interfaces 121, the number of interfaces between the earphone head module 1 and the earphone accessories 2 is expanded, the electric connection channels between the earphone head module 1 and the earphone accessories 2 are increased, and more functional elements can be placed in the earphone head module 1, so that the earphone head module 1 and the earphone assembly can realize more functions.

[0065] In a further embodiment, one of the first interface 121 and the second interface 211 is a stretchable conductive elastic needle 121b, and the other is a conductive sheet 121a.

[0066] As shown in Figure 1 and Figure 2 , the plurality of first interfaces 121 are all conductive sheets 121a, and the plurality of second interfaces 211 are all stretchable conductive elastic needles 121b.

[0067] By arranging one of the first interface 121 and the second interface 211 as a conductive elastic needle 121b, the reliability and fault tolerance of the electrical connection between the earphone head module 1 and the earphone accessories 2 can be improved; in the case that the cooperation gap between the earphone head module 1 and different earphone accessories 2 is different, the conductive elastic needle 121b can ensure reliable connection between the earphone head module 1 and each earphone accessory 2 through its adaptive stretching; by arranging the other of the first interface 121 and the second interface 211 as a conductive sheet 121a, the conductive sheet 121a and the conductive elastic needle 121b are ensured to be in full contact, so that the connection between the conductive sheet 121a and the conductive elastic needle 121b is more stable and less likely to be disconnected.

[0068] In a further embodiment, the first electric connection mechanism 12 further comprises a first auxiliary connection structure 122, and the earphone accessory 2 further comprises a second auxiliary connection structure 212, and the first auxiliary connection structure 122 and the second auxiliary connection structure 212 are detachably connected.

[0069] Exemplarily, the first auxiliary connection structure 122 and the second auxiliary connection structure 212 are detachably connected through snap connection, pin connection, magnetic connection, threaded connection, etc.

[0071] In one specific embodiment, the first auxiliary connecting structure 122 and the second auxiliary connecting structure 212 are both magnetic pieces, and the first auxiliary connecting structure 122 and the second auxiliary connecting structure 212 can be magnetically attracted.

[0072] In this embodiment, the earphone head module 1 and the earphone accessory 2 are magnetically attracted by the magnetic attraction force between the first auxiliary connecting structure 122 and the second auxiliary connecting structure 212, the connection reliability and stability of the earphone head module 1 and the earphone accessory 2 are improved, and the earphone accessory 2 connected with the earphone head module 1 is facilitated to be replaced.

[0073] Further, the first auxiliary connecting structure 122 is in a strip shape, and the two ends of the first auxiliary connecting structure 122 in the length direction are different magnetic poles; the second auxiliary connecting structure 212 is in a strip shape, and the two ends of the second auxiliary connecting structure 212 in the length direction are different magnetic poles.

[0075] In one embodiment, the first electric connecting mechanism 12 has a first end face 123, and the second electric connecting mechanism 21 has a second end face 213. As shown in Figure 1 and Figure 2 , the first auxiliary connecting structure 122 is convex relative to the first end face 123, and the second end face 213 is provided with a receiving groove 2131, so that the first auxiliary connecting structure 122 is magnetically attracted to the second auxiliary connecting structure 212 through the receiving groove 2131, and the shape and size of the receiving groove 2131 are respectively matched with the shape and size of the first auxiliary connecting structure 122; or the second auxiliary connecting structure 212 is convex relative to the second end face 213, and the first end face 123 is provided with a receiving groove 2131, so that the second auxiliary connecting structure 212 is magnetically attracted to the first auxiliary connecting structure 122 through the receiving groove 2131, and the shape and size of the receiving groove 2131 are respectively matched with the shape and size of the second auxiliary connecting structure 212.

[0076] By setting the accommodating groove 2131, the first auxiliary connecting structure 122 or the second auxiliary connecting structure 212 protruding outward plays a limiting role, which helps to avoid relative rotation of the earphone head module 1 and the earphone accessory 2.
