[0043] As shown in Figure 3As shown in the drawings, the microphone assembly 1 comprises a microphone unit 11, a first electrode unit 12 and a first connecting member, the first electrode unit 12 is connected to one side of the microphone unit 11 and arranged in the first connecting member, and the first connecting member is a locking member 13.

[0044] As shown in the drawings, Figure 3 and Figure 4 the microphone unit 11 comprises a first cantilever housing 111, a second cantilever housing 112 and at least one microphone, in this embodiment, two microphones are included, one is a main microphone 113 and the other is a secondary microphone 114. In order to facilitate the installation of the microphone, the first cantilever housing 111 and the second cantilever housing 112 are in butt joint structure, and the inside of the two after butt joint forms a containing space, the main microphone 113 and the secondary microphone 114 are located in the containing space, and the main microphone 113 and the secondary microphone 114 are electrically connected with the first electrode unit 12. Among them, the first cantilever housing 111 and the second cantilever housing 112 can be clamped or bonded as a whole.

[0045] As shown in the drawings, Figure 4 the earphone assembly 2 comprises an earphone body 21, a second electrode unit 22 and an earphone shell 23, the earphone body 21 and the second electrode unit 22 are arranged in the earphone shell 23, and the main control assembly 3 is electrically connected with the second electrode unit 22 and the earphone body 21 respectively. In order to facilitate the installation of the earphone body 21 and the second electrode unit 22, the earphone shell 23 can comprise an upper shell 235 and a lower shell 236 which can be detachably connected.

[0046] In the utility model, the detachable structure includes but is not limited to the following several forms.

[0047] As shown in the drawings, Figures 2-4 and Figure 6 one embodiment is that the inner wall of the locking member 13 is provided with an internal thread 131, the inside of the locking member 13 is provided with a first cavity to accommodate the first electrode unit 12, the second connecting member is an external thread 231 arranged on the earphone shell 23, the internal thread 131 of the locking member 13 and the external thread 231 of the earphone assembly 2 are screw connected, and then the detachable connection between the earphone assembly 2 and the microphone assembly 1 is realized through the relative rotation between the locking member 13 and the earphone shell 23. Of course, in the actual application process, the external thread can also be arranged on the outer wall of the locking member 13, and correspondingly, the internal thread is arranged on the inner wall of the earphone shell 23.

[0048] As shown in the drawings, Figures 7-9As shown, one embodiment is that the inner wall of the locking piece 13 is provided with at least one first buckle 132, the second connecting piece is a second buckle 232 provided on the earpiece shell 23, the second buckle 232 is provided in one-to-one correspondence with the first buckle 132, when the locking piece 13 and the earpiece shell 23 are docked, the bottom end of the second buckle 232 on the earpiece shell 23 is pressed against the top end of the first buckle 132 to realize the connection and locking of the microphone assembly 1 and the earpiece assembly 2. In the actual application process, when only one first buckle 132 and one second buckle 232 are provided, the length of the first buckle 132 in the circumferential direction should have a certain length to ensure the reliability of the first buckle 132 and the second buckle 232 when they are docked, and to avoid the locking piece 13 from being directly separated from the earpiece shell 23 of the earpiece assembly 2 due to accidental loosening, resulting in falling. When a plurality of second buckles 232 are provided, the plurality of second buckles 232 are arranged at intervals, and the interval between the adjacent two second buckles 232 should be greater than the length of the first buckle 132 in the circumferential direction, so as to smoothly insert the first buckle 132 on the locking piece 13 into the gap between the adjacent two second buckles 232 on the earpiece shell 23, and then rotate to press the bottom end of the second buckle 232 against the top end of the first buckle 132, realizing the connection of the earpiece assembly 2 and the microphone assembly 1. Of course, in this scheme, to ensure reliability, the first buckle 132 and the second buckle 232 also need to have a certain length in the circumferential direction. For example Figure 8 As shown, to realize quick docking, a stop rib 233 is provided below any second buckle 232 to stop the first buckle 132, avoiding multiple rotations for positioning.

[0049] Among them, to realize better docking, the first buckle 132 and the second buckle 232 are mutually male and female buckles, that is, one is convex and the other is concave. The locking piece 13 is sleeved into the connecting side of the earpiece shell 23 and rotated clockwise (or counterclockwise) to lock the locking piece 13, and the rotation stops at the stop rib 233 position. At this time, the two buckles are engaged together, and the self-locking effect is achieved. At this time, the rotation of the locking piece 13 has no radial and axial momentum with the earphone main body assembly, and force is needed to lock or disassemble.

[0050] For example Figure 10 and Figure 11As shown, one embodiment is that the inner wall of the locking member 13 is provided with at least one spiral guide groove 133, and the second connecting member is a guide post 234 provided on the earphone housing 23, the guide post 234 is correspondingly arranged with the spiral guide groove 133, when the locking member 13 is connected with the earphone assembly 2, the guide post 234 is located at the tail end of the spiral guide groove 133 to lock the locking member 13 and the earphone housing 23. In order to avoid the loosening of the locking member 13 and the earphone housing 23 after being connected, the tail end of the spiral guide groove 133 is downwardly communicated with a clamping groove 134 in the spiral direction, the guide post 234 is clamped into the clamping groove 134 to lock the guide post 234 and ensure the reliability of the connection between the locking member 13 and the earphone housing 23. When the two need to be unlocked, the guide post 234 is separated from the clamping groove 134, and the like. Figure 11 As shown, the locking member 13 is pressed downwardly, and then the spiral guide groove 133 moves downwardly relative to the guide post 234, the guide post 234 moves upwardly relative to the spiral guide groove 133, that is, the guide post 234 is separated from the clamping groove 134, and then the locking member 13 is reversely screwed to realize the unlocking of the two. In the actual application, after the locking member 13 and the earphone housing 23 are connected, the side end surface of the locking member 13 facing the earphone housing 23 and the earphone housing 23 need to be reserved a pressing or lifting interval P in the vertical direction to ensure that the guide post 234 and the clamping groove 134 are smoothly separated or entered into the clamping groove 134. Of course, in the embodiment, in order to facilitate the manufacturing of the clamping groove 134, a through hole can be punched from the outside to the inside. The shape of the guide post 234 can be circular, oval or track-shaped, etc.

[0051] In the embodiment of the utility model, for realizing that the microphone unit 11 can rotate 360 DEG and stay, to adapt to the mouth position of different use objects, improve the comfort of earphone wearing, the detachable earphone still includes the damping sheet 14. Among them, the second cantilever shell 112 of the microphone unit 11 forms the connecting end part of the microphone assembly 1, the second cantilever shell 112 has coaxially arranged first annular protrusion 1121 and second annular protrusion 1122, the height of first annular protrusion 1121 is greater than the height of second annular protrusion 1122, locking piece 13 is set on the outside of first annular protrusion 1121 and can rotate relative to first annular protrusion 1121. When locking piece 13 is connected with earphone shell 23, locking piece 13 is fixed relative to earphone shell 23, when rotating the microphone unit 11, first annular protrusion 1121 on the second cantilever shell 112 rotates relative to locking piece 13, and then the rotation of the microphone unit 11 is realized. Specifically, the first annular protrusion 1121 and the second annular protrusion 1122 form a containing groove for placing the damping sheet 14, and the end face of the locking piece 13 towards the connecting end part of the microphone assembly 1 is frictionally connected with the damping sheet 14. The damping sheet 14 between the locking piece 13 and the second cantilever shell 112 of the microphone unit 11 increases the damping feeling of the rotation of the microphone unit 11, and ensures that it can stay at any angle. The frictional resistance of the damping sheet 14 can be realized by adjusting the thickness, hardness or material of the damping sheet 14, and the material can be PVC, silicone sheet, nylon sheet, etc. Of course, the frictional resistance can also be realized by adjusting the pre-pressing amount.

[0052] Since the microphone unit 11 can rotate 360 DEG, to ensure that the wire connected with the microphone in the microphone unit 11 does not wind, the first electrode unit 12 rotates synchronously with the microphone unit 11.

[0053] As shown in Figure 6 The first electrode unit 12 includes a magnet 121, a first fixed seat 122 and an electrode copper ring plate 123, the magnet 121 is arranged on one side of the first fixed seat 122 towards the connecting end part of the microphone assembly 1, the electrode copper ring plate 123 is arranged on one side of the first fixed seat 122 towards the earphone assembly 2, and the first fixed seat 122 is sleeved in the first annular protrusion 1121. To facilitate the installation of the locking piece 13, the outer wall surface of the first fixed seat 122 is partially radially protruded to form an abutting ring 1221, the abutting ring 1221 cooperates with the damping sheet 14 to axially clamp the locking piece 13, and the locking piece 13 rotates coaxially relative to the first annular protrusion 1121.

[0054] Correspondingly, the second electrode unit 22 is located inside the earpiece housing 23. The second electrode unit 22 includes a connected Hall sensor 221, a connecting plate 224, a connecting wire group 222, and a plurality of copper pillars 223. The Hall sensor 221 is located at the center of the connecting plate 224, and the plurality of copper pillars 223 are located on the connecting plate 224 with the top of the copper pillars 223 extending out of the top of the earpiece housing 23. When the first connector and the second connector are connected, the copper pillars 223 are correspondingly connected to the electrode copper ring plate 123.

[0055] The electrode copper ring plate 123 has multiple concentric, spaced copper rings, the number of which corresponds to the number of solder pads required for the main microphone 113 and the secondary microphone 114. Figure 12 As shown, in this embodiment, the main microphone 113 and the secondary microphone 114 together include four solder pins, each solder pin corresponding to a copper ring. Therefore, the electrode copper ring plate 123 includes four copper rings, with a certain spacing between each copper ring. The width of the copper rings must ensure good contact between the copper posts 223, and insulation treatment is applied between the copper rings. When the positive and negative wires of the main microphone 113 and the secondary microphone 114 are connected to the four copper rings, the four copper rings represent the positive and negative terminals of the main microphone 113 and the secondary microphone 114, respectively.

[0056] like Figure 13 As shown, the multiple copper pillars 223 of the second electrode unit 22 are distributed in a concentric radial array. It should be noted that each copper ring is provided with at least one copper pillar 223. To ensure the reliability of the contact, each copper ring can be provided with a pair of copper pillars 223 at intervals. The copper pillars 223 are pin copper pillars. The material of the copper pillars 223 can be copper or other conductive metal materials. Of course, spring contact can also be used to replace the copper pillar 223 electrode. The copper pillars 223 are connected to the main control component 3 through the connecting wire group 222 on the connecting plate 224.

[0057] In practical applications, the cantilever housing of the microphone unit 11 can rotate, allowing the microphone to be adjusted relative to the user's mouth for optimal sound transmission when worn by different people. The head of the copper post 223 is movable, and it has a pre-pressure on the copper ring of the corresponding electrode copper ring plate 123 to ensure normal contact between the two without affecting the rotation of the cantilever housing. Each copper ring on the electrode copper ring plate 123 is a complete circle, ensuring good contact between the copper ring of the electrode copper ring plate 123 and the copper post 223 on the connecting plate 224 at any angle of 360° when the cantilever housing rotates, thus ensuring that the circuit forms a complete loop.

[0058] In this configuration, the Hall sensor 221 of the second electrode unit 22 is located directly below the magnet 121 of the first electrode unit 12. The distance between them ensures that the Hall sensor 221 can sense the magnetic force of the magnet 121, and that the magnetic force is sufficient to drive the Hall sensor 221. When the earpiece assembly 2 and the microphone assembly 1 are connected, during the microphone transmission phase, the earpiece is powered on. The Hall sensor 221 senses the magnetic force of the magnet 121 and sends a signal. The main control assembly 3 connects to the copper ring on the first electrode unit 12 through the copper post 223 on the second electrode unit 22, thereby powering the main microphone 113 and the secondary microphone 114. At this time, the circuits of the main microphone 113 and the secondary microphone 114 are fully connected and in a working state, i.e., microphone transmission.

[0059] When the microphone assembly 1 is removed from the earpiece assembly 2, even if the earphone is powered on, there is no magnetic field provided by the magnet 121 to the Hall sensor 221, and there is no signal. The main control assembly 3 will not supply power to the copper pillar 223. At this time, the copper pillar 223 exposed on the earphone body is in a non-powered state and will not form a short circuit when there is water or sweat.

[0060] To enable the detachable earphones to be waterproof and sweatproof, the detachable earphones also include a sealing ring 15. The sealing ring 15 is disposed on the first fixing base 122. When the first connector and the second connector are connected, the sealing ring 15 is located between the outer wall of the first fixing base 122 and the connecting end of the earpiece assembly 2, so that the copper pillar 223 and the cavity of the electrode copper ring plate 123 form a sealed space, which plays a role in waterproofing and sweatproofing.

[0061] like Figure 5 As shown, in this embodiment, the main control component 3 includes a main housing 31, a charging board 32, a button 33, a main control circuit board, and a battery 35. The charging board 32, the button 33, the main control circuit board, and the battery 35 are all disposed inside the main housing 31. The battery 35 supplies power to the main control circuit board. The main control circuit board is electrically connected to the connecting plate 224 and the earpiece body 21 in the earpiece component 2.
