[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In one embodiment of the present invention, an earphone is provided, which includes a stem, a connection base and an earphone cavity cover, wherein the connection base and the earphone cavity cover are rotatably connected by means of a convex point and a concave groove, and when the connection base rotates relative to the earphone cavity cover, the convex point can be effectively engaged in the concave groove. Figures 1 to 7 The earphones in this embodiment are further described as shown.

[0028] Specifically, if Figure 1 and Figure 2 As shown, the earphone in this embodiment includes: a stem 1, a connecting seat 2 and an earphone cavity cover 3.

[0029] The stem 1 is connected to the connection seat 2, the connection seat 2 is provided with a plug-in column 4, the radial outer periphery of the plug-in column 4 is provided with a protrusion 5, the earphone cavity cover 3 is provided with a plug-in hole 6, the inner wall surface of the plug-in hole 6 is provided with a plurality of grooves 7 at intervals along its circumferential direction, the plug-in column 4 can be rotatably inserted into the plug-in hole 6, and the protrusion 5 is engaged and snapped into the groove 7.

[0030] For example, the earphone in this embodiment is a headset, which may include a headband, an ear shell, and a functional element. The headband is generally constructed as a U-shaped frame structure, which can be mounted on the user's head, the ear shell is connected to the end of the headband, and the functional element is arranged in the ear shell. When the user wears the earphone, the ear shell can reach the user's ear.

[0031] In one embodiment, the functional element includes a speaker module. When a user wears the headset, the speaker module can be close to the user's ear and can emit sound.

[0032] In one embodiment, the functional element further includes a control module, the speaker module is electrically connected to the control module, and the control module can obtain an external control signal to control the speaker module to emit sound. Of course, the control module can also be set externally, for example, it can be set on the head ring or other positions.

[0033] In one embodiment, the functional element further includes a battery module, which is electrically connected to the control module. The battery module can provide electrical energy for the normal operation of the control module, thereby ensuring that the speaker module can produce sound normally.

[0034] In one embodiment, the speaker module can be connected to an external control module via a cable, and then the cable provides power and control signal to the speaker module so that the speaker module can emit sound normally.

[0035] Moreover, there can be two ear shells, which are respectively connected to the two ends of the head ring, and functional elements such as speaker modules are arranged in the two ear shells.

[0036] Furthermore, in this embodiment, the earphone cavity cover 3 can be fixedly connected to the ear shell. For example, the earphone cavity cover 3 can be fixedly connected to the ear shell by means of structures such as bolts or by a clamping method.

[0037] The speaker rod 1 is connected to the earphone cavity cover 3 via the connection base 2, and the speaker rod 1 is used to obtain sound information in the external environment, for example, Figure 3 As shown, the speaker stick 1 is provided with a microphone module 8. When the user speaks to the microphone module 8, the microphone module 8 can obtain corresponding sound information in real time.

[0038] In one embodiment, the microphone module 8 can be electrically connected to the control module, and the sound information obtained by the microphone module 8 can be transmitted to the control module. Thereafter, the control module processes the sound information. For example, the control module can convert the sound information into other forms of information and send it to the outside.

[0039] In one embodiment, the microphone module 8 can be connected to an external control module via a cable, and then the cable provides power to the microphone module 8 and transmits the sound information of the microphone module 8 to the control module.

[0040] In this embodiment, in order to facilitate the adjustment of the position of the stem 1 , the connection base 2 is rotatably connected to the earphone cavity cover 3 .

[0041] Specifically, if Figure 4 As shown, the connecting seat 2 is provided with a plug-in column 4, and the plug-in column 4 can be constructed as a cylindrical structure. The radial outer periphery of the plug-in column 4 is provided with a protrusion 5, and the protrusion 5 protrudes outward along the radial direction of the plug-in column 4. The number of the protrusion 5 can be one or more. When there are multiple protrusions 5, the multiple protrusions 5 can be arranged at intervals along the circumferential direction of the plug-in column 4, and can also be arranged at intervals along the radial direction of the plug-in column 4.

[0042] Moreover, the protrusions 5 can be directly arranged on the circumferential outer surface of the plug-in column 4, or can be arranged on the radial outer periphery of the plug-in column 4 with the aid of other supporting structures.

[0043] For example, in this embodiment, if Figure 4 As shown, a plurality of arc-shaped spring sheets are arranged on the radial outer periphery of the plug-in post 4 , and the arc-shaped spring sheets are separated from each other. The protrusions 5 are arranged on the outer surface of the arc-shaped spring sheets away from the plug-in post 4 .

[0044] It can be understood that by arranging the protrusion 5 on the arc-shaped spring piece, during the process of the protrusion 5 being snapped into different grooves 7, the arc-shaped spring piece can produce elastic deformation in the radial direction of the plug-in column 4, so that the protrusion 5 can achieve a short-distance displacement in the radial direction of the plug-in column 4, thereby reducing the wear of the protrusion 5, and ensuring that the protrusion 5 can be snapped into the groove 7 during long-term use, further improving the service life.

[0045] like Figure 5 As shown, the earphone cavity cover 3 is provided with a plug-in hole 6, the inner diameter of the plug-in hole 6 matches the outer diameter of the plug-in column 4, and the circumferential inner wall surface of the plug-in hole 6 is provided with a plurality of grooves 7, which are arranged at intervals along the circumferential direction of the plug-in hole 6, and the protrusion 5 on the plug-in column 4 can be snapped into the groove 7.

[0046] In one embodiment, an annular boss is provided on one side of the earphone cavity cover 3 facing the connecting socket 2, the annular boss protrudes from the end surface of the earphone cavity cover 3, and the plurality of grooves 7 are provided on the inner wall surface of the annular boss.

[0047] In actual use, when the user puts on headphones and needs to adjust the position of the speaker stem 1, the user can rotate the connecting seat 2. At this time, the plug-in column 4 of the connecting seat 2 will rotate in the plug-in hole 6 of the earphone cavity cover 3. During the rotation of the plug-in column 4 relative to the plug-in hole 6, the protrusion 5 on the plug-in column 4 can be snapped into different grooves 7 in turn. When the speaker stem 1 is rotated to the required position, the protrusion 5 can be snapped into the groove 7 at the corresponding position, and the speaker stem 1 can hover at the current position.

[0048] In this embodiment, through the above-mentioned setting method, the protrusion 5 on the connecting seat 2 will not fall off, nor will it produce excessive wear. Even after long-term use, the protrusion 5 can be effectively snapped into the groove 7 of the earphone cavity cover 3, thereby ensuring that the phone stem 1 can be accurately suspended at the required position during long-term use, which can meet the user's usage needs and ensure that the user has a good usage experience.

[0049] Furthermore, in the present embodiment, there are a plurality of protrusions 5 , and the plurality of protrusions 5 are arranged at intervals along the circumferential direction of the plug-in column 4 , and the plurality of protrusions 5 can be respectively snapped into the plurality of grooves 7 .

[0050] It can be understood that the plug-in column 4 needs to rotate in the plug-in hole 6. If the number of protrusions 5 is small or the setting position is too concentrated, the plug-in column 4 may be offset in the plug-in hole 6. At this time, by setting multiple protrusions 5 at even intervals in the circumferential direction of the plug-in column 4, and making the multiple protrusions 5 able to be snapped into the groove 7, the snap-in between the multiple protrusions 5 and the groove 7 can be used to ensure that the plug-in column 4 can always be at the axial position of the plug-in hole 6 to ensure accurate position. At the same time, since the multiple protrusions 5 can be snapped into the groove 7, the position between the connecting seat 2 and the earphone cavity cover 3 can also be ensured to be stable, and the position of the speaker rod 1 will not be changed due to the rotation of the connecting seat 2 relative to the earphone cavity cover 3 due to the accidental touching of the speaker rod 1.

[0051] In a specific embodiment, the plug-in column 4 is evenly spaced with 5 protrusions 5 in the circumferential direction, and the inner wall surface of the plug-in hole 6 is spaced with 25 grooves in the circumferential direction, and each protrusion 5 can be snapped into the corresponding groove 7. At this time, in the process of rotating the connecting seat 2, when the protrusion 5 changes its position from the current groove 7 to the adjacent groove 7, the adjustment range of 14.4° can be achieved for each gear.

[0052] Furthermore, if Figure 2As shown, the earphone further includes a connecting piece 9 , which is connected to the end of the plug-in column 4 extending out of the plug-in hole 6 , and the connecting piece 9 is used to limit the plug-in column 4 from falling off from the plug-in hole 6 .

[0053] For example, in the process of producing and assembling headphones, the plug-in post 4 of the connecting socket 2 needs to be plugged into the plug-in hole 6 of the headphone cavity cover 3. At this time, the plug-in post 4 partially extends into the plug-in hole 6. In order to prevent the plug-in post 4 from falling off from the plug-in hole 6, the position of the plug-in post 4 needs to be limited.

[0054] In this regard, in this embodiment, after the plug-in column 4 is inserted into the plug-in hole 6, the end of the plug-in column 4 can extend beyond the plug-in hole 6, and the end that is inserted and extends beyond the plug-in hole 6 is connected to a connecting piece 9. While ensuring that the plug-in column 4 can rotate relative to the plug-in hole 6, the plug-in column 4 can be prevented from falling off from the plug-in hole 6.

[0055] As an implementation method, the connecting piece 9 can be a nut, and the end of the plug-in column 4 extending out of the plug-in hole 6 is provided with an external thread, and the nut can be threadedly connected to the external thread. The outer diameter of the nut is larger than the inner diameter of the plug-in hole 6. Thus, the plug-in column 4 can be limited by means of the nut to prevent the plug-in column 4 from falling off from the plug-in hole 6.

[0056] As an implementation method, the connecting piece 9 can be a pin, and the end of the plug-in column 4 extending out of the plug-in hole 6 is provided with a pin hole penetrating along the radial direction of the plug-in hole 6, and the pin can be inserted in the pin hole. The length of the pin is greater than the inner diameter of the plug-in hole 6. Thus, the plug-in column 4 can be limited by means of the pin to prevent the plug-in column 4 from falling off from the plug-in hole 6.

[0057] In this embodiment, for the convenience of installation, Figure 2 and Figure 7 As shown, the connecting member 9 is a clip spring, and the end of the plug-in column 4 extending out of the plug-in hole 6 is provided with a clip groove, and the clip spring is clipped into the clip groove.

[0058] Exemplarily, the end of the plug-in column 4 is provided with a snap-in groove extending along its circumferential direction. After the plug-in column 4 is inserted into the plug-in hole 6, the snap-in groove can extend to the outside of the plug-in hole 6 along the end of the plug-in column 4. Then, the retaining spring is snapped into the snap-in groove. Moreover, the radial length of the retaining spring can be greater than the inner diameter of the plug-in hole 6, so that the plug-in column 4 can be limited by means of the retaining spring to prevent the plug-in column 4 from falling off from the plug-in hole 6.

[0059] In one embodiment, in order to facilitate the connection between the speech rod 1 and the connecting socket 2, the connecting socket 2 is provided with a mounting hole, and the first end of the speech rod 1 is provided with a microphone module 8, and the second end is inserted into the mounting hole.

[0060] For example, Figure 3As shown, the speaker rod 1 is constructed as a long strip structure with a certain length. In the length direction of the speaker rod 1, a microphone module 8 is provided at the first end of the speaker rod 1, and the second end is used to be inserted into the connecting socket 2.

[0061] For example, Figure 4 As shown, the connection base 2 is roughly constructed as an L-shaped structure, one end of the connection base 2 is provided with a plug-in column 4, and the other end is an extension portion, the extension portion is roughly perpendicular to the plug-in column 4, and the mounting hole is provided in the extension portion.

[0062] During actual production and assembly, the second end of the speech rod 1 can be directly plugged into the mounting hole of the connecting seat 2, thereby achieving the connection between the speech rod 1 and the connecting seat 2.

[0063] Furthermore, in one embodiment, the mounting hole is a square hole with a rectangular cross section, and the second end of the speech rod 1 is constructed as a rectangular column adapted to the mounting hole.

[0064] It can be understood that by setting the mounting hole as a square hole and making the second end of the speech rod 1 a rectangular column, after the second end of the speech rod 1 is connected to the mounting hole, the speech rod 1 can be prevented from rotating relative to the connecting seat 2, thereby ensuring that the speech rod 1 can be stably connected to the connecting seat 2.

[0065] Of course, in other embodiments, in order to achieve a stable connection between the speech rod 1 and the connecting seat 2, the second end of the speech rod 1 can be made into other structures. For example, the cross-section of the speech rod 1 can be constructed into a triangle, a pentagon or other shapes, and the shape of the mounting hole can be adapted to the cross-section of the speech rod. It is only necessary to prevent the speech rod 1 from rotating relative to the connecting seat 2.

[0066] Alternatively, in one embodiment, a structure such as a latch may be provided between the speech rod 1 and the connection base 2 to prevent the speech rod 1 from rotating relative to the connection base 2 .

[0067] Furthermore, in order to effectively limit the depth of the second end of the speech rod 1 inserted into the mounting hole, an abutment groove is provided at the opening of the mounting hole, and an abutment block 10 is provided on the outer wall surface of the speech rod 1, and the abutment block 10 abuts against the abutment groove in the length direction of the speech rod 1.

[0068] For example, the abutment groove can be configured as an annular groove surrounding the opening of the mounting hole, in which case the mounting hole and the abutment groove are jointly formed as a stepped hole. The abutment block 10 can be configured as an annular flange surrounding the outer wall of the stem.

[0069] like Figure 2 As shown, after the second end of the speech rod 1 is inserted into the mounting hole of the connecting seat, the abutment block 10 can enter the abutment groove, and in the length direction of the speech rod 1, the abutment block 10 can abut against the inner wall surface of the abutment groove.

[0070] Therefore, during production and assembly, the installation position of the stem 1 relative to the connecting seat 2 can be determined by means of the abutment between the abutment block 10 and the abutment groove.

[0071] Of course, in other embodiments, the abutment groove can also be other through grooves. During assembly, it is only necessary to ensure that the abutment block on the outer wall of the stem 1 can fully abut against the abutment groove, and thereby determine the insertion depth of the stem 1 relative to the connecting seat 2.

[0072] In one embodiment, Figure 2 As shown, the headset also includes a fixing block 11, a fixing groove 12 is provided on the side of the second end of the stem 1, and the connecting seat 2 is provided with a through hole 13 connected to the mounting hole. The fixing block 11 is installed in the through hole 13 and can be snapped into the fixing groove 12.

[0073] For example, Figure 3 As shown, the second end of the stem 1 can be partially inserted into the mounting hole of the connecting seat 2, and a fixing groove 12 is provided on the side of the inserting portion.

[0074] For example, Figure 4 As shown, a through hole 13 is provided in the extension portion of the connection base 2, and the through hole 13 is vertically connected to the mounting hole.

[0075] During production and assembly, after the second end of the speech rod 1 is inserted into the mounting hole of the connecting seat 2, the fixing groove 12 on the speech rod 1 can reach the position corresponding to the through hole 13. Then, the fixing block 11 can be installed in the through hole 13 and one end of the fixing block 11 can be clamped in the fixing groove 12. The clamping connection between the fixing block 11 and the fixing groove 12 can prevent the speech rod 1 from falling off from the mounting hole.

[0076] For example, Figure 6 As shown, the fixing block 11 can be roughly constructed as a rectangular block structure.

[0077] In one embodiment, Figure 4 and Figure 5 As shown, the connecting seat 2 is provided with an annular groove 14, which surrounds the circumferential side of the plug-in column 4, and the fixing block 11 is at least partially placed in the annular groove 14. The earphone cavity cover 3 is provided with a limiting boss 15, which is clamped in the annular groove 14. The limiting boss 15 can abut against the fixing block 11 in the circumferential direction of the annular groove 14.

[0078] For example, Figure 4As shown, on the connection base 2, the outer circumference of the plug-in column 4 is sequentially spaced along its radial direction, and an annular groove 14 is formed between the two annular flanges. Moreover, the through hole 13 is placed between the two annular flanges. At this time, one side of the through hole 13 is connected to the mounting hole, and the other side is connected to the annular groove 14. When the fixing block 11 is inserted into the through hole 13, one end of the fixing block 11 can enter the mounting hole and can be used to be clamped to the fixing groove 12 of the stem 1, and the other end can remain in the annular groove 14.

[0079] For example, Figure 5 As shown, on the earphone cavity cover 3 , a limiting boss 15 is provided on the end surface of the annular boss facing the connecting socket 2 . The limiting boss 15 is roughly constructed in an arc shape, and the position of the limiting boss 15 corresponds to that of the annular groove 14 .

[0080] When the connection base 2 and the earphone cavity cover 3 are connected to each other, the limiting boss 15 can be snapped into the annular groove 14, and the limiting boss 15 can move in the annular groove 14 during the rotation of the connection base 2 relative to the earphone cavity cover 3. Moreover, since one end of the fixing block 11 is placed in the annular groove 14, the limiting boss 15 can abut against the fixing block 11 in the circumferential direction of the annular groove 14 during the movement of the limiting boss 15 in the annular groove 14.

[0081] Therefore, through the above-mentioned setting method, with the help of the fixing block 11, the rotation angle of the connecting socket 2 relative to the earphone cavity cover 3 can be limited.

[0082] That is to say, during actual production and manufacturing, a limiting boss 15 with a certain position and length can be set on the earphone cavity cover 3 according to the rotation angle requirement of the stem 1.

[0083] In one embodiment, a wiring hole 16 is also provided in the connecting socket 2, one end of the wiring hole 16 is connected to the mounting hole, and the other end passes through the end of the plug-in column 4, and a cable connected to the microphone module 8 is provided in the telephone stem 1, and the cable extends from the second end of the telephone stem 1 and is inserted into the wiring hole 16.

[0084] like Figure 3 As shown, a microphone module 8 is disposed at the first end of the boom 1 , and a cable connected to the microphone module 8 can extend from the second end of the boom 1 .

[0085] like Figure 4 As shown, a wiring hole 16 is provided at the axial center position of the plug-in column 4 , one end of the wiring hole 16 can be connected to the mounting hole, and the other end passes through the end of the plug-in column 4 .

[0086] In actual installation, Figure 2As shown, after the second end of the speech rod 1 is plugged into the mounting hole of the connecting socket 2, the cable extending from the second end of the speech rod 1 can extend out through the wiring hole 16. Thus, after the connecting socket 2 and the earphone cavity cover 3 are connected, and the earphone cavity cover 3 is connected to the ear shell, the cable connected to the microphone module 8 can enter the ear shell and connect with the functional components inside the ear shell.

[0087] In addition, the connection between the wiring hole 16 and the mounting hole may also be provided with a chamfered structure or a rounded structure, so that when the cable enters the wiring hole 16 from the mounting hole, sufficient space can be reserved for the bending of the cable, ensuring that the cable can bend normally.
