[0029] In the above embodiment, the shell 100 is designed to include the hanging neck part 110, the first support part 120 and the second support part 130, wherein the hanging neck part is used to comfortably hang on the back of the human neck, and the first support part and the second support part extend to the front of the human neck to form a stable hanging neck area, which is used to hang on the human neck, so that the first support part 120 and the second support part 130 are arranged corresponding to the human mouth. This design ensures that the microphone can be closer to the sound source, i.e. the user's mouth, thereby effectively improving the clarity and sensitivity of sound pickup and reducing the interference of environmental noise. The first microphone 200 and the second microphone 300 are rotatably arranged with the first support part 120 and the second support part 130 through the first connecting portion 220 and the second connecting portion 320. This design allows the microphone to adjust the angle according to the specific position and direction of the speaker, solving the problem of sound pickup dead angle caused by the fixed position of the traditional microphone. In particular, through the first rotating shaft 230 and the second rotating shaft 330, the microphone rotates in the vertical plane, ensuring that the microphone can accurately aim at the sound source no matter which side the speaker is located, thereby greatly improving the sound pickup effect. An electrical control module is arranged in the first microphone 200 and the second microphone 300, which is not only responsible for signal processing and transmission, but also can be connected with an external loudspeaker. The electrical control module can dynamically adjust the sound pickup gain and noise suppression parameters according to the rotation angle of the microphone and the environmental noise by integrating intelligent algorithms, ensuring that high-quality voice signals can be captured in various complex environments.

[0030] Specifically, the first microphone 200 further comprises a first rotating shaft 230, which is arranged through the first connecting portion 220 and connected with the first support portion 120, so that the first microphone 200 is rotationally connected with the first support portion 120; the second microphone 300 further comprises a second rotating shaft 330, which is arranged through the second connecting portion 320 and connected with the second support portion 130, so that the second microphone 300 is rotationally connected with the second support portion 130. The first microphone 200 is rotationally connected with the first support portion 120 through the first rotating shaft 230, so as to ensure that the microphone can be flexibly adjusted in angle according to the position of the speaker. Similarly, the second microphone 300 is rotationally connected with the second support portion 130 through the second rotating shaft 330, so as to provide omnidirectional sound pickup effect and ensure that the best sound pickup effect can be obtained regardless of whether the speaker is located on the left side or the right side.

[0031] Specifically, the first support portion 120 is provided with a first groove 121, which is arranged along the extension direction of the first support portion 120, and the first microphone 200 is arranged in the first groove 121; the second support portion 130 is provided with a second groove 131, which is arranged along the extension direction of the second support portion 130, and the second microphone 300 is arranged in the second groove 131. The first groove 121 on the first support portion 120 and the second groove 131 on the second support portion 130 not only provide the assembly space of the microphone, but also enhance the stability and aesthetic degree of the whole through the integrated design with the outer shell 100. The microphone is embedded in the groove, which on the one hand can protect the microphone from external collision damage, and on the other hand is helpful to the streamline design of the whole microphone and improves the wearing comfort.

[0032] In the above embodiment, the first groove 121 and the second groove 131 are arranged at the end portions of the first support portion 120 and the second support portion 130 respectively, so that at least part of the first microphone 200 and the second microphone 300 protrude from the side of the end portions of the first support portion 120 and the second support portion 130, which facilitates taking out from the groove during use.

[0033] Specifically, the end of the first rotating shaft 230 is connected with the side wall of the first groove 121 close to one end of the hanging neck part 110, and the axis of the first rotating shaft 230 is arranged perpendicularly to the extension direction of the first support part 120 so that the first microphone 200 rotates around the first rotating shaft 230; the end of the second rotating shaft 330 is connected with the side wall of the second groove 131 close to one end of the hanging neck part 110, and the axis of the second rotating shaft 330 is arranged perpendicularly to the extension direction of the second support part 130 so that the second microphone 300 rotates around the second rotating shaft 330. The first rotating shaft 230 and the second rotating shaft 330 serve as connecting members, and the axes thereof are arranged perpendicularly to the extension direction of the corresponding support part, which ensures that the microphone can rotate smoothly in the vertical plane without affecting the overall structure and wearing feeling of the hanging neck microphone. The rotating shaft plays a core role in rotating support and guidance and is the key to realizing the angle adjustment of the microphone.

[0034] In some embodiments, the end of the first rotating shaft 230 is connected with the side wall of the first groove 121 away from one end of the hanging neck part 110, and the end of the second rotating shaft 330 is connected with the side wall of the second groove 131 away from one end of the hanging neck part 110. The first groove 121 and the second groove 131 are provided with a avoiding part close to one end of the hanging neck part 110, and the avoiding part is an arc-shaped groove, and the arc-shaped end of the arc-shaped groove is arranged at the end of the avoiding part away from the microphone, so that when the first microphone 200 and the second microphone 300 are stored in the groove, the user can put his fingers into the avoiding part to take out the first microphone 200 and the second microphone 300.

[0035] Specifically, a plurality of first clamping groove parts 201 are arranged on the first microphone 200, a first protruding part 121a is arranged on the first groove 121, and the plurality of first clamping groove parts 201 are arranged correspondingly with the first protruding part 121a, so that when the first microphone 200 rotates, the first protruding part 121a is clamped and matched with one of the plurality of first clamping groove parts 201; a plurality of second clamping groove parts 301 are arranged on the second microphone 300, a second protruding part 131a is arranged on the second groove 131, and the plurality of second clamping groove parts 301 are arranged correspondingly with the second protruding part 131a, so that when the second microphone 300 rotates, the second protruding part 131a is clamped and matched with one of the plurality of second clamping groove parts 301. The combination of the first clamping groove part 201 and the first protruding part 121a and the combination of the second clamping groove part 301 and the second protruding part 131a constitute a positioning and locking mechanism of the microphone. When the microphone rotates to a certain preset angle, the protruding part is clamped and matched with the corresponding clamping groove part, so that the position of the microphone is fixed. By clamping and matching the groove and the protruding part, the position of the microphone is fixed, the angle is prevented from changing during use, and the sound pickup effect is ensured.

[0036] Specifically, a plurality of first clamping groove portions 201 are arranged on the first connecting portion 220 in a circumferential direction around the first rotating shaft 230, and two adjacent first clamping groove portions 201 are arranged at intervals; a plurality of second clamping groove portions 301 are arranged on the second connecting portion 320 in a circumferential direction around the second rotating shaft 330, and two adjacent second clamping groove portions 301 are arranged at intervals. The plurality of first clamping groove portions 201 and the plurality of second clamping groove portions 301 are arranged radially, and the specific layout of the clamping groove portions and the clamping protrusions, i.e., arranged at intervals in the circumferential direction of the rotating shaft, ensures that the microphone can have multiple preset rotating positions, improving the ability of the microphone to adapt to different use scenarios. The neck lengths of different people are different, and this multi-angle positioning function enhances the user's custom options for the product, so that each user can find the most suitable microphone position for themselves. The first microphone 200 is provided with a first sound pickup portion 210 at one end away from the first connecting portion 220, and the second microphone 300 is provided with a second sound pickup portion 310 at one end away from the second connecting portion. When the angle needs to be adjusted, the microphone is rotated so that the first sound pickup portion 210 or the second sound pickup portion 310 rotates around the predetermined axis, and the clamping groove portions slide and clamp between the protrusions in turn, so that the first sound pickup portion 210 or the second sound pickup portion 310 is adjusted to the appropriate angle, making the sound pickup effect better.

[0037] Specifically, a first rotating portion is arranged between the first support portion 120 and the neck hanging portion 110, and a second rotating portion is arranged between the second support portion 130 and the neck hanging portion 110. The first rotating portion and the second rotating portion are rotating shafts, and the first support portion 120 and the second support portion 130 are respectively rotatably connected to the neck hanging portion 110 through the rotating shafts. The rotating portions between the first support portion 120 and the neck hanging portion 110 and between the second support portion 130 and the neck hanging portion 110 allow the support portions to rotate relative to the neck hanging portion, thereby increasing the adjustable range of the microphone, not limited to vertical rotation, but also allowing horizontal angle adjustment, further optimizing the sound pickup effect and wearing comfort.

[0038] Specifically, the outer surface layer of the first support part 120 and the second support part 130 is made of flexible material, and the internal support structure of the first support part 120 and the second support part 130 is made of titanium alloy material. The combination of the flexible material of the outer surface layer and the titanium alloy material of the internal support structure ensures that the first support part 120 and the second support part 130 have better wearing experience while ensuring structural strength. The flexible material reduces friction and compression on the skin, while the titanium alloy provides the required firmness and lightness, both of which work together to achieve the best balance of functionality and comfort. In this embodiment, the microphone is fixedly connected with the support part, and the angle adjustment of the microphone relative to the human mouth is achieved through the rotatable design between the support part and the neck hanging part. When the angle of the microphone needs to be adjusted, the titanium alloy support is bent to the desired shape, which allows the microphone to be adjusted in the vertical plane and the width of the neck hanging area to be adjusted according to the thickness of the neck of different users, preventing the neck hanging microphone from falling off, improving the comfort of wearing, and further improving the sound pickup effect.

[0039] Specifically, the shell 100 further comprises a magnetic attraction piece 140, which is arranged on the first groove 121 and the second groove 131, and the first microphone 200 and the second microphone 300 are respectively magnetically attracted to the magnetic attraction piece 140, so that the first microphone 200 and the second microphone 300 are magnetically connected with the shell 100. The arrangement of the magnetic attraction piece 140 provides an additional positioning and fixing method for the microphone. When the microphone is stored in the groove from the rotating position, the magnetic attraction piece can ensure that the microphone is safely attracted to the shell 100, avoiding accidental falling of the microphone from the groove during carrying or wear of the microphone.

[0040] Specifically, the shell 100 is provided with a power key, which is connected with the electrical control module circuit and used for turning on or off the neck hanging microphone; the shell 100 is provided with a charging port, and the shell 100 is provided with a battery module, which is connected with the electrical control module circuit; the shell 100 is provided with a battery compartment for placing a battery, and the battery compartment is connected with the electrical control module circuit. The power key, the charging port and the battery compartment are part of the electrical control system, directly related to the electrical control module, and jointly build the energy management system of the neck hanging microphone. The power key is used to control the switch of the microphone, and the charging port and the battery compartment are used to provide continuous power supply, whether through built-in battery charging or external battery replacement, to ensure that the microphone can operate stably for a long time and meet the user's use demand in different occasions.
