[0045] Embodiment 1

[0046] This embodiment provides an ear tip assembly that can achieve the switching of different sound qualities, enabling users to use the required ear tip assembly in different environments, enhancing the user experience, and enriching the functions of the ear tip assembly. In this embodiment, the ear tip assembly is applied to headphones, such as wireless headphones, in-ear headphones.

[0047] As Figure 1 and Figure 2 shown, the ear tip assembly includes an ear tip 1, a support member 2, and a tuning member 3.

[0048] Among them, the ear cap 1 can extend into the user's ear canal and be elastically plugged into the user's ear canal. The material of the ear cap 1 is an elastic material. In some embodiments, the material of the ear cap 1 is silica gel, rubber, etc. The outer wall of the ear cap 1 may be provided with a rough structure to increase the friction between the ear cap 1 and the user's ear canal and prevent the ear cap 1 from falling off. The specific structure of the ear cap 1 can refer to the prior art. For example, Figure 3 As shown, the ear cap 1 in this embodiment includes an integrally formed outer elastic part 13 and an inner concave part 12 located inside the outer elastic part 13. The inner concave part 12 has a hollow columnar structure.

[0049] Please refer to Figure 3 , the support member 2 is fixedly connected inside the ear cap 1, specifically fixedly connected to the inner concave part 12, and the support member 2 has an assembly groove 21. The tuning member 3 is fixedly arranged in the assembly groove 21. Specifically, as Figure 4 shown, the tuning member 3 includes a tuning unit 31 fixedly arranged in the assembly groove 21 and two elastic pieces 32 respectively electrically connected to the tuning unit 31. In this embodiment, the tuning unit 31 has a positive extreme and a negative extreme. One elastic piece 32 is electrically connected to the positive extreme, and the other elastic piece 32 is electrically connected to the negative extreme. Moreover, the two elastic pieces 32 are configured to be electrically connected to the control circuit of the earphone. It can be understood that the tuning member 3 in this embodiment can be a moving iron component, such as a moving iron speaker. The tuning unit 31 can be the moving iron unit in the moving iron speaker in the prior art. The internal structure of the tuning unit 31 can determine the nature or specification of the tuning unit 31. When tuning units 31 of different specifications are connected to the speaker 20, the sound quality, pitch or other parameters of the sound emitted by the speaker 20 are different. Optionally, the elastic piece 32 and the tuning unit 31 in this embodiment are connected by welding.

[0050] In this embodiment, the ear cap 1 and / or the support member 2 are detachably connected to the front shell 10 of the earphone, thereby realizing the detachable connection of the ear cap assembly and the front shell 10, so that when the user has different sound requirements, it can be achieved by replacing the ear cap assembly.

[0051] The ear cap assembly provided in this embodiment fixes the tuning member 3 on the ear cap 1 through the support member 2, so that the ear cap assembly can adjust parameters such as the sound quality or pitch of the earphone. When the user uses it in different application scenarios, the change of parameters such as sound quality or pitch can be achieved by replacing different ear cap assemblies, realizing the switching of different sound qualities, enhancing the user experience, enriching the functions of the ear cap assembly, and the ear cap 1 or the support member 2 is detachably connected to the front shell 10 of the earphone, facilitating the replacement of the ear cap assembly.

[0052] Optionally, as Figure 1As shown, the ear cap assembly further includes a flexible printed circuit board 4 (Flexible Printed Circuit, abbreviated as FPC). Two elastic pieces 32 respectively elastically abut against one end of the flexible printed circuit board 4, and the other end of the flexible printed circuit board 4 is used for electrical connection with the control circuit of the earphone. That is, the elastic pieces 32 are electrically connected to the control circuit through the flexible printed circuit board 4. The flexible printed circuit board 4 is made of a relatively soft material, so that the flexible printed circuit board 4 can be threaded between the functional components in the earphone or between the functional components and the front shell 10, and thus will not interfere with the arrangement of the functional components.

[0053] Further, as Figure 6 shown, one end of the flexible printed circuit board 4 has a negative contact piece 41 and a positive contact piece 42. The elastic piece electrically connected to the positive extreme of the tuning unit 31 abuts against the positive contact piece 42, and the elastic piece electrically connected to the negative extreme of the tuning unit 31 abuts against the negative contact piece 41. At the same time, the positive contact piece 42 is electrically connected to the positive pole of the control circuit through the wire in the flexible printed circuit board 4, and the negative contact piece 41 is electrically connected to the negative pole of the control circuit through the wire in the flexible printed circuit board 4. By way of example, please refer to Figure 6 , the positive contact piece 42 is in a semi-circular ring shape, the negative contact piece 41 is in a circular shape, and the positive contact piece 42 is wound around the positive contact piece 42.

[0054] In some embodiments, as Figure 4 and Figure 5 shown, the elastic piece 32 includes a main body portion 321 electrically connected to the tuning unit 31 and an abutting portion 322 connected to the main body portion 321. The main body portion 321 is in a sheet shape, and the main body portion 321 is in planar contact with the positive extreme or the negative extreme to have a relatively large contact area. The abutting portion 322 is in an S shape, and one end of the abutting portion 322 is connected to the main body portion 321, and the other end of the abutting portion 322 is used for elastically abutting against the positive contact piece 42 or the negative contact piece 41 at one end of the flexible printed circuit board 4. The S-shaped abutting portion 322 can realize the elastic abutment between the elastic piece 32 and the flexible printed circuit board 4, with a simple structure and without occupying a large space. It should be noted that the abutting portion 322 can be formed by bending a long sheet-shaped structure, so that the abutting portion 322 has a relatively large contact area with the flexible printed circuit board 4. At this time, the longitudinal section of the abutting portion 322 is in an S shape. In some other embodiments, the elastic piece 32 can include a spring and a contact piece, and the spring is electrically connected between the tuning unit 31 and the contact piece, and the contact piece elastically abuts against one end of the flexible printed circuit board 4.

[0055] In this embodiment, the shape and size of the main body portion 321 of one elastic piece 32 may be the same as or different from those of the main body portion 321 of the other elastic piece 32, which can be determined according to actual needs. The elastic piece 32 in this embodiment is an integrally formed structure to have relatively high structural strength.

[0056] Please continue to refer to Figure 3, the support member 2 further has a sound outlet hole 23 penetrating through both ends along its extending direction, and the sound outlet hole 23 is used for the sound emitted by the speaker 20 to pass through. In this embodiment, the sound outlet hole 23 and the assembly groove 21 are arranged at intervals. Optionally, the sound outlet hole 23 is semicircular or arcuate, and this embodiment does not limit this. In some embodiments, there is one sound outlet hole 23; in other embodiments, there are multiple sound outlet holes 23, and the multiple sound outlet holes 23 are evenly and spacedly distributed.

[0057] In this embodiment, please refer to Figure 3 , the assembly groove 21 extends along the extending direction of the support member 2, and the extending direction of the support member 2 can be the assembly direction of the ear cap assembly and the front shell 10. Moreover, the support member 2 further includes a bottom plate 27 located at the bottom of the assembly groove 21, a through hole 22 penetrating through the bottom plate 27, and a partition plate 28 spaced between the assembly groove 21 and the sound outlet hole 23. The bottom plate 27, the partition plate 28 and one side of the support member 2 together form the above-mentioned assembly groove 21, and the partition plate 28 and the other side of the support member 2 together form the above-mentioned sound outlet hole 23.

[0058] As Figure 4 shown, the tuning unit 31 has a convex portion 311 extending into the through hole 22. In some embodiments, the convex portion 311 is press-fitted in the through hole 22. The setting of the through hole 22 can, on the one hand, improve the fixing firmness of the tuning unit 31 in the assembly groove 21, and on the other hand, the sound emitted by the speaker 20 can pass through the assembly groove 21 and the through hole 22 and out of the ear cap assembly. In this embodiment, the through hole 22 is a cylindrical hole, and the convex portion 311 is cylindrical. Optionally, the shape of the assembly groove 21 in this embodiment is square to cooperate with the tuning member 3, and the tuning unit 31 is square. The convex portion 311 is, for example, the sound outlet structure of the tuning unit 31.

[0059] Optionally, as Figure 7 shown, the inner wall of the concave portion 12 has a clamping groove 11. As Figure 8 shown, the support member 2 includes a clamping portion 24 and a cylindrical portion 25 connected to one side of the clamping portion 24. The clamping portion 24 is clamped in the clamping groove 11 to improve the connection strength between the support member 2 and the ear cap 1. The assembly groove 21 is provided on the end face of the cylindrical portion 25 that is not connected to the clamping portion 24. Moreover, as Figure 8 shown, the side surface of the cylindrical portion 25 is provided with an external thread for screwing with the front shell 10 of the earphone.

[0060] Furthermore, please continue to refer to Figure 7 , the groove wall of the clamping groove 11 has a receiving groove 14 perpendicular to the clamping groove 11. One end of the clamping portion 24 that is not connected to the cylindrical portion 25 is provided with a convex strip 26, and the convex strip 26 is placed in the receiving groove 14 to assist the clamping groove 11 in limiting the support member 2.

[0061] Optionally, in this embodiment, the ear cap 1 and the support member 2 are integrally injection-molded structures, that is, the ear cap 1 and the support member 2 can be integrally molded by in-mold injection, so that the ear cap 1 and the support member 2 have a high connection strength and are not easily separated.

[0062] Optionally again, in this embodiment, the tuning unit 31 is press-fitted, welded, riveted or adhered to the support member 2. Specifically, the tuning unit 31 is press-fitted, welded or adhered to the groove wall of the assembly groove 21. When the tuning unit 31 is riveted to the support member 2, one of the support member 2 and the tuning unit 31 has a mortise and tenon structure, and the other has a groove structure matching the mortise and tenon structure, so that the tuning unit 31 and the support member 2 are firmly fixed to prevent the tuning unit 31 from separating from the support member 2.

[0063] Optionally, the ear cap assembly may further include a protective cover, which is used to cover the elastic piece 32 when the ear cap assembly is not connected to the front shell, so as to prevent the elastic piece 32 from being oxidized and corroded.

[0064] The ear cap assembly provided in this embodiment has a simple structure, is easy to manufacture, has a low cost, can realize the adjustment of sound quality, and has rich functions.

[0065] Embodiment Two

[0066] This embodiment provides a headset, as Figures 9 to 11 shown, the headset includes a front shell 10, a speaker 20, a control circuit and the ear cap assembly in Embodiment One.

[0067] Among them, the speaker 20 is fixedly arranged in the front shell 10 and electrically connected to the control circuit. The ear cap 1 and / or the support member 2 are detachably connected to the front shell 10, and both elastic pieces 32 of the ear cap assembly are electrically connected to the control circuit. The control circuit in the speaker 20 can be a control circuit in the prior art, which can control the sound quality, pitch, etc. emitted by the speaker 20 according to the performance parameters of the tuning unit 31. In this embodiment, the case where the support member 2 is detachably connected to the front shell 10 is given.

[0068] Optionally, as Figure 10 shown, the support member 2 is snap-fitted to the front shell 10; alternatively, the outer wall of the support member 2 has an external thread, the front shell 10 has a convex portion 101, and the inner wall of the convex portion 101 has an internal thread, and the support member 2 and the front shell 10 are connected by the screwed external thread and internal thread.

[0069] As Figure 11 shown, the flexible circuit board 4 extends into the front shell 10 through the convex portion 101 of the front shell 10 and is electrically connected to the control circuit.

[0070] It can be understood that the headset may further include other functional components, and the connection methods and installation positions of other functional components can refer to the prior art, which will not be elaborated in this embodiment.

[0071] When using the earphone provided in this embodiment, the support member 2 is screwed with the front shell 10. When the screwing is in place, the elastic piece 32 can tightly abut against the flexible circuit board 4, thereby realizing the electrical connection between the tuning unit 31 and the control circuit. That is to say, in this embodiment, the flexible circuit board 4 is always electrically connected to the control circuit. When replacing different ear cap assemblies, the flexible circuit board 4 in the ear cap assembly does not need to be replaced, but only the ear cap 1, the support member 2 and the tuning member 3 need to be replaced. When it is necessary to replace the ear cap assembly, the support member 2 can be directly detached from the front shell 10, which is convenient for operation.
