[0044] Please see Figures 1 to 3This application provides a magnetic snap fastener assembly 100, including a first fastener 10 and a second fastener 20. The first fastener 10 includes a first body 11 and a first bar magnet 12. The first body 11 has an annular groove 111. The outer edge of the annular groove 111 has two first inner snaps 1121 facing each other along a first direction A1, and the inner edge of the annular groove 111 has two first outer snaps 1131 facing away from each other along the first direction A1. The first bar magnet 12 is fixed to the first body 11, with the first direction A1 and the second direction A2 perpendicular to each other. The second fastener 20 includes a second body 21, a sliding portion 22, and a second bar magnet 23. The sliding portion 22 is slidably mounted on the second body 21 along a third direction A3. The sliding portion 22 has second outer snaps 221 and second inner snaps 222 distributed along the third direction A3. The second bar magnet 23 is fixed to the sliding portion 22, with the third direction A3 and the fourth direction A4 perpendicular to each other. Figures 4 to 6 When the second outer buckle 221 and the second inner buckle 222 enter the annular groove 111, the first bar magnet 12 and the second bar magnet 23 can attract each other and align, thus combining. Figure 7 The first direction A1 and the third direction A3 are parallel, and the second outer buckle 221 is fastened to one of the first inner buckles 1121, and the second inner buckle 222 is fastened to one of the first outer buckles 1131.

[0045] The outer edge and the inner edge of the annular groove 111 are arranged facing each other. The outer edge of the annular groove 111 is located outside the inner edge of the annular groove 111.

[0046] The first inner buckle 1121 extends from the outer edge of the annular groove 111 toward the central axis of the annular groove 111. The first outer buckle 1131 extends from the inner edge of the annular groove 111 away from the central axis of the annular groove 111. The second outer buckle 221 extends from the sliding portion 22 away from the central axis of the sliding portion 22. The second inner buckle 222 extends from the sliding portion 22 toward the central axis of the sliding portion 22.

[0047] The perpendicularity of the first direction A1 and the second direction A2 can be absolute, or it can be close to perpendicular. For example, an angle of 90° ± 10° between the first direction A1 and the second direction A2 is allowed. The case where the third direction A3 and the fourth direction A4 are perpendicular is similar.

[0048] When the first bar magnet 12 and the second bar magnet 23 are aligned, the extension direction of the first bar magnet 12 and the extension direction of the second bar magnet 23 are parallel, and the relative area of ​​the first bar magnet 12 and the second bar magnet 23 is the largest.

[0049] The magnetic snap fastener assembly 100 provided in this application embodiment is connected by a first snap fastener 10 and a second snap fastener 20 using a magnetic attraction method. The first body 11 of the first snap fastener 10 has two first inner snaps 1121 and two first outer snaps 1131 arranged along a first direction A1, with the two first outer snaps 1131 located between the two first inner snaps 1121. A first bar magnet 12 is fixed to the first body 11. The second body 21 of the second snap fastener 20 has a second outer snap 221 and a second inner snap 222 arranged along a third direction A3. A second bar magnet 23 is fixed to a sliding part 22, which is slidably mounted on the second body 21 along the third direction A3. When assembling the first snap fastener 10 and the second snap fastener 20, the second outer snap 221 and the second inner snap 222 are brought close to the annular groove 111 of the first body 11. Under the magnetic force of the first bar magnet 12 and the second bar magnet 23, the second outer snap 221 and the second inner snap 222 will automatically enter the annular groove 111. Furthermore, there is no need for manual adjustment of the relative angles of the first fastener 10 and the second fastener 20 to make the first direction A1 and the third direction A3 parallel. Within a certain angle range (e.g., ±30°) between the first direction A1 and the third direction A3, under the magnetic force of the first bar magnet 12 and the second bar magnet 23, combined with... Figure 7 The first bar magnet 12 and the second bar magnet 23 have a tendency to move in opposite directions, enabling them to automatically align and make the first direction A1 and the third direction A3 parallel. The sliding part 22 slides relative to the second body 21, causing the second outer buckle 221 to engage with a first inner buckle 1121, and the second inner buckle 222 to engage with a first outer buckle 1131. This achieves automatic fastening of the first fastener 10 and the second fastener 20, ensuring reliable connection and convenient assembly. The first fastener 10 and the second fastener 20 cannot be directly separated. Figure 8 , Figure 9 When disassembling the first fastener 10 and the second fastener 20, the relative angle position of the first fastener 10 and the second fastener 20 is changed so that the first direction A1 and the third direction A3 are perpendicular. The second outer fastener 221 disengages from the first inner fastener 1121, and the second inner fastener 222 disengages from the first outer fastener 1131. This allows the first fastener 10 and the second fastener 20 to be separated, making the separation operation convenient.

[0050] In some embodiments, please refer to Figure 2 The first bar magnet 12 and the second bar magnet 23 can both be cuboids, and their sizes are similar. The large faces of the first bar magnet 12 and the second bar magnet 23 are arranged facing each other, so that a large magnetic attraction can be formed between the two adjacent bar magnets.

[0051] like Figure 5As shown, when the second outer buckle 221 and the second inner buckle 222 are inserted into the annular groove 111 of the first body 11, the first bar magnet 12 and the second bar magnet 23 are offset along the first direction A1 or the third direction A3. Under the magnetic force between the first bar magnet 12 and the second bar magnet 23, the first bar magnet 12 and the second bar magnet 23 tend to move towards each other, making the first direction A1 and the third direction A3 parallel, the second direction A2 and the fourth direction A4 parallel, the long sides of the two magnets aligned along the second direction A2, and the short sides of the two magnets aligned along the first direction A1.

[0052] In some embodiments, please refer to Figures 1 to 3 The first strip magnet 12 extends along the second direction A2, and the second strip magnet 23 extends along the fourth direction A4. Alternatively, the first strip magnet 12 extends along the first direction A1, and the second strip magnet 23 extends along the third direction A3. When the second outer buckle 221 and the second inner buckle 222 are inserted into the annular groove 111 using the above scheme, under the magnetic force of the first strip magnet 12 and the second strip magnet 23, the first strip magnet 12 and the second strip magnet 23 tend to move towards each other, enabling the first strip magnet 12 and the second strip magnet 23 to automatically align, thus achieving automatic fastening of the first fastener 10 and the second fastener 20. For some embodiments, please refer to... Figures 1 to 3 The first body 11 includes an annular portion 112 and a connecting portion 113 that are relatively stationary. The connecting portion 113 is located inside the annular portion 112, and an annular groove 111 is formed between the annular portion 112 and the connecting portion 113. Two first inner buckles 1121 are connected to the annular portion 112, and two first outer buckles 1131 are connected to the connecting portion 113. The annular portion 112 and the connecting portion 113 are independent structural components, which are easy to form and assemble. A first strip magnet 12 is fixed to the connecting portion 113. When the first fastener 10 and the second fastener 20 are assembled, a large magnetic attraction force can be generated between the first strip magnet 12 and the second strip magnet 23. The sliding portion 22 is driven to slide relative to the second body 21 by the magnetic attraction force, thereby realizing the corresponding inner and outer buckle engagement.

[0053] In some embodiments, please refer to Figures 1 to 3 Both the annular portion 112 and the connecting portion 113 are fixed to the base 114. The annular portion 112 and the connecting portion 113 are assembled on the base 114, and the annular portion 112, the connecting portion 113 and the base 114 form an annular groove 111.

[0054] For example, the connecting part 113 and the base 114 can be connected by means of adhesive bonding, fasteners (such as screws), etc. The positioning pin of the base 114 can be inserted into the positioning hole of the connecting part 113 to position the connecting part 113 on the base 114. The annular part 112 can be installed on the base 114 by means of adhesive bonding, fasteners (such as screws), etc.

[0055] In some embodiments, please refer to Figure 2 , Figure 3 The connecting portion 113 has a first receiving groove 1132, and the first strip magnet 12 is disposed in the first receiving groove 1132. Disposing of the first strip magnet 12 in the connecting portion 113 can reduce the space occupied by the first body 11 and protect the first strip magnet 12.

[0056] The sliding part 22 has a second receiving groove 223, and the second strip magnet 23 is disposed in the second receiving groove 223. By disposing of the second strip magnet 23 in the sliding part 22, the space occupied by the second body 21 can be reduced, and the second strip magnet 23 can be protected.

[0057] In some embodiments, please refer to Figure 2 , Figure 3 The first inner buckle 1121 is crescent-shaped, and the first direction A1 passes through the middle 1121a of the first inner buckle 1121. The width of the crescent-shaped first inner buckle 1121 is the largest at the middle, and the width of the first inner buckle 1121 gradually decreases from the middle to the end. When the first inner buckle 1121 and the second outer buckle 221 are fastened, they are not easy to detach, and the connection is reliable. Adjusting the relative position of the first fastener 10 and the second fastener 20, so that the second outer buckle 221 moves to the gap between the two first inner buckles 1121, allows the first inner buckle 1121 and the second outer buckle 221 to detach.

[0058] In some embodiments, please refer to Figure 2 , Figure 3 The first outer buckle 1131 is crescent-shaped, with the first direction A1 passing through the middle 1131a of the first outer buckle 1131. The width of the crescent-shaped first outer buckle 1131 is greatest in the middle, and the width of the first outer buckle 1131 gradually decreases from the middle to the end. When the first outer buckle 1131 and the second inner buckle 222 are fastened together, they are not easily detached, and the connection is reliable. Adjusting the relative position of the first fastener 10 and the second fastener 20, so that the second inner buckle 222 moves to the gap between the two first outer buckles 1131, allows the first outer buckle 1131 and the second inner buckle 222 to disengage.

[0059] In some embodiments, please refer to Figure 2 , Figure 3 The second outer buckle 221 is crescent-shaped, with the third direction A3 passing through the middle 221a of the second outer buckle 221. The width of the crescent-shaped second outer buckle 221 is the largest in the middle, and the width of the second outer buckle 221 gradually decreases from the middle to the end. When the first inner buckle 1121 and the second outer buckle 221 are fastened, they are not easy to detach, and the connection is reliable. Adjusting the relative position of the first fastener 10 and the second fastener 20, so that the second outer buckle 221 moves to the gap between the two first inner buckles 1121, allows the first inner buckle 1121 and the second outer buckle 221 to detach.

[0060] In some embodiments, please refer to Figure 2 , Figure 3 The second inner buckle 222 is arc-shaped, and the third direction A3 passes through the middle 222a of the second inner buckle 222. When the first outer buckle 1131 and the second inner buckle 222 are fastened, they are not easy to detach, and the connection is reliable. Adjusting the relative position of the first fastener 10 and the second fastener 20, so that the second inner buckle 222 moves to the gap between the two first outer buckles 1131, allows the first outer buckle 1131 and the second inner buckle 222 to detach.

[0061] In some embodiments, please refer to Figure 1 , Figure 4 The second body 21 is configured as a clip 21a for clamping onto a predetermined object. The clip 21a can be clamped onto a shoulder strap, belt, or other strap. When the magnetic snap assembly 100 is applied to an electronic device, the electronic device can be easily and detachably connected to the strap. The second body 21 can be a flexible clip 21a that provides a certain clamping force when clamping an object, ensuring that the clip 21a is reliably clamped onto the predetermined object. The electronic device can be a wearable speaker, etc.

[0062] In some embodiments, please refer to Figures 10 to 12 The second body 21 is configured as a bracket fastener 21b for assembly onto a bicycle computer bracket. A conventional bicycle computer bracket can be mounted on the bicycle handlebars for mounting a camera, computer, and lights. The bracket fastener 21b can be assembled onto the bicycle computer bracket using fasteners (such as screws). When the magnetic snap-on assembly 100 is applied to electronic devices, it allows for convenient detachable connection of the electronic device to the bicycle handlebars. The electronic device can be a wearable speaker, etc.

[0063] In some embodiments, please refer to Figure 1 The first body 11 has a lanyard hole 1122 for a lanyard to pass through. Instead of assembling the second buckle 20 onto the first buckle 10, the lanyard is passed through the lanyard hole 1122 of the first body 11, allowing it to be hung around the user's neck. When the magnetic buckle assembly 100 is applied to electronic devices, it allows the electronic device to be conveniently hung around the user's neck. The electronic device can be a wearable speaker, etc.

[0064] In some embodiments, please refer to Figure 3 , Figure 5The sliding part 22 has a guide surface 224. During the insertion of the second outer buckle 221 and the second inner buckle 222 into the annular groove 111, the guide surface 224 and the edge of the annular groove 111 abut against each other, causing the sliding part 22 to move along a third direction A3. This allows the second inner buckle 222 and the second outer buckle 221 of the sliding part 22 to smoothly insert into the annular groove 111. Moreover, the first bar magnet 12 and the second bar magnet 23 are offset along the first direction A1 or the third direction A3. When the second inner buckle 222 and the second outer buckle 221 are fully inserted into the annular groove 111, under the magnetic attraction of the first bar magnet 12 and the second bar magnet 23, the second bar magnet 23 fixed to the sliding part 22 moves along the third direction A3, and the first bar magnet 12 and the second bar magnet 23 are aligned. The second outer buckle 221 is fastened to a first inner buckle 1121, and the second inner buckle 222 is fastened to a first outer buckle 1131.

[0065] For example, the sliding part 22 has a ring-shaped part 2241 that can extend into the annular groove 111 of the first body 11, and the end face of the ring-shaped part 2241 has a guide surface 224 with an arc-shaped cross-section.

[0066] In some embodiments, please refer to Figure 3 , Figure 5 The second body 21 is provided with a guide portion 211, and the sliding portion 22 has a guide groove 225 extending along a third direction A3. The walls of the guide portion 211 and the guide groove 225 are slidably engaged, so that the sliding portion 22 is slidably mounted on the second body 21. The guide portion 211 and the second body 21 are easy to form and assemble. The slidable engagement of the guide portion 211 and the guide groove 225 enables the sliding portion 22 to be slidably mounted on the second body 21 along a third direction A3.

[0067] For example, the guide portion 211 and the guide groove 225 are adapted in cross-sectional shape perpendicular to the third direction A3, so that the guide portion 211 is slidably mounted on the guide groove 225. The guide portion 211 has a T-shaped cross-sectional shape perpendicular to the third direction A3, and the guide groove 225 is a T-shaped groove.

[0068] By providing two sets of guide parts 211 and guide grooves 225, the sliding part 22 is reliably slidably mounted on the second body 21 along the third direction A3.

[0069] In some embodiments, please refer to Figure 3 , Figure 5 The second body 21 has two limiting walls 212 distributed along a third direction A3 to limit the sliding range of the sliding part 22 along the third direction A3. When the sliding part 22 moves to one of the limiting walls 212, it is blocked by the limiting wall 212 and cannot continue to move, thus limiting the sliding range of the sliding part 22.

[0070] Please see Figure 1 , Figure 4 , Figure 12 This application provides an electronic device including the magnetic snap assembly 100 described above.

[0071] This electronic device adopts all the technical solutions of all the above embodiments, and therefore has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0072] Electronic devices can take many forms. For example, an electronic device can be a wearable speaker, small in size and multifunctional. A wearable speaker can be a Bluetooth speaker capable of high-volume playback; it can have a walkie-talkie module for group chat; it can have a flashlight for illumination; and it can have a built-in storage chip for storing audio files. Wearable speakers are suitable for outdoor scenarios such as hiking and cycling.

[0073] Please see Figure 1 , Figure 13 , Figure 14 This application provides a wearable speaker 1000 with intercom function, including a housing 200, a microphone 95, a speaker 93, an intercom module (not shown), and the aforementioned magnetic buckle assembly 100. The first body 11 is disposed in the housing 200, and the microphone 95, speaker 93 and intercom module are all disposed in the housing 200.

[0074] The housing 200 serves as the mounting carrier for components such as the microphone 95, speaker 93, and walkie-talkie module. The microphone 95, also known as a microphone, is an energy conversion device that converts sound signals into electrical signals. The speaker 93 is an energy conversion device that converts electrical signals into sound. The walkie-talkie module is the core integrated circuit used in wireless walkie-talkies. The microphone 95, speaker 93, and walkie-talkie module all utilize conventional technology. Connecting the microphone 95, speaker 93, and walkie-talkie module to the motherboard 90, which contains a controller, enables the walkie-talkie function.

[0075] The wearable speaker 1000 with intercom function provided in this application embodiment has a first body 11 of the magnetic buckle assembly 100 disposed on the housing 200. The first fastener 10 and the second fastener 20 are easy to assemble and detach, and the two fasteners are reliably connected. The microphone 95, speaker 93 and intercom module disposed on the housing 200 are combined to enable the wearable speaker 1000 to have long-distance intercom function in outdoor scenarios, allowing users to communicate with each other.

[0076] In some embodiments, see Figure 13 , Figure 14The housing 200 includes a housing 210 and a cover 220. The housing 210 has an opening 211, and the cover 220 is disposed at the opening 211. The housing 210 and the cover 220 can be fixedly connected by fasteners (such as screws), clips, etc. The internal cavity formed by the housing 210 and the cover 220 can be used to install devices. The base 114 can be connected to the housing 210.

[0077] In some embodiments, see Figure 13 , Figure 14 The microphone 95 and the through-hole 212 of the housing 210 are positioned opposite each other. External sound travels through the through-hole 212 to the microphone 95, where it is picked up. The speaker 93 is located at the opening 221 of the cover 220 and outputs sound outward. The sound-emitting side of the speaker 93 and the sound-collecting surface of the microphone 95 face different directions to reduce the sound pickup interference of the speaker 93 to the microphone 95. The speaker 93 and the microphone 95 can be respectively located in isolated spaces within the housing 200 to reduce the sound pickup interference of the speaker 93 to the microphone 95. For example, a silicone part 951 can be used within the housing 200 to form two isolated spaces.

[0078] In some embodiments, see Figure 13 , Figure 14 The housing 210 may be provided with a mesh cover 80, which is located at the opening 21 of the cover 20. The mesh cover 80 can be used to protect the speaker 93 at the opening 21 of the cover 20. The sound emitted by the speaker 93 is transmitted outward through the mesh cover 80.

[0079] In some embodiments, see Figure 13 , Figure 14 The housing 200 is equipped with a battery 94, which is connected to the motherboard 90 and can provide power to various electronic devices.

[0080] In some embodiments, see Figure 13 , Figure 14 It also includes a flashlight assembly 92 disposed in the housing 200. The flashlight assembly 92 includes a light source 921 and a lens 922, with the lens 922 disposed on the light-emitting side of the light source 921. The light emitted by the light source 921 is processed by the lens 922 and then emitted outward, realizing the flashlight function. The light source 921 is electrically connected to the main board 90.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
