Description

Technical Field

[0001] This utility model belongs to the field of electroacoustic component technology, and in particular relates to a magnetically detachable microphone structure. Background Technology

[0002] Microphones, as core electroacoustic components that convert sound signals into electrical signals, are widely used in various audio devices. Currently, most microphones are connected to devices via fixed connections, such as soldering, screw fastening, or interference fit insertion. These connection methods are inconvenient for disassembly and assembly: disassembly requires specialized tools (such as soldering irons and screwdrivers), making the process complex, and repeated disassembly and assembly can easily lead to solder joint detachment, stripped screws, or damaged interfaces, increasing equipment maintenance costs.

[0003] To address this, Chinese Patent No. CN221381141U discloses a wireless microphone with a replaceable microphone, comprising a body and a microphone. The end face of the body has a magnetic attachment point, and the microphone has a suction connector distributed on the side facing the magnetic attachment point. The suction connector includes a movable post and a suction head. The movable post is inserted through the side wall of the microphone and is elastically connected to the microphone. The suction head is attached to the end of the movable post facing away from the side wall of the microphone. When the microphone is connected to the body, the suction head is attached to the magnetic attachment, allowing the same microphone to switch between different sound recording effects at any time.

[0004] However, although the above-mentioned device connects the microphone to the equipment through magnetic attraction, making it easy to disassemble the microphone, it is susceptible to external force during the process of carrying the equipment. This can cause the magnetic joint to loosen or develop gaps, resulting in poor sealing and tightness. It may even cause the microphone to fall and be damaged, affecting the efficiency of use. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a magnetically detachable microphone structure, which has the advantages of strong connection, good sealing, high stability and good anti-drop effect. It solves the problem that in the prior art, when carrying the device, external forces can easily cause the magnetic joint to loosen and gap, resulting in poor sealing and tightness, and may even cause the microphone to fall and be damaged, affecting the efficiency of use.

[0006] This utility model is implemented as follows: a magnetically detachable microphone structure includes a device body and a microphone body. The device body includes an interface seat and a first conductive terminal mounted on its end face. The microphone body includes a shell and a second conductive terminal. A slot is formed on the end face of the microphone body. A protrusion adapted to the slot is fixedly mounted on the interface seat. Magnetic iron pieces are fixedly connected to the top of both the slot and the protrusion. The magnetic iron pieces are mutually attracted and fixed. The second conductive terminal passes through the magnetic iron pieces and the protrusion and is elastically connected to the first conductive terminal. Silicone sealing gaskets are fixedly connected to the interface seat and the bottom of the shell corresponding to the periphery of the protrusion. The silicone sealing gaskets are tightly fitted together. Limiting components are installed between the outer walls of the shell and the interface seat on both sides. The limiting components include a limiting bent plate and a U-shaped locking rod. When the microphone body and the interface seat are magnetically fixed, the U-shaped locking rod is inserted into the inner side of the limiting bent plate.

[0007] In a preferred embodiment of this invention, the card protrusion has a receiving hole, the first conductive terminal is located at the receiving hole, and the second conductive terminal extends into the receiving hole and elastically contacts and connects with the first conductive terminal. The first conductive terminal is a gold-plated conductive contact, and the second conductive terminal is a Pogo Pin spring pin.

[0008] With this setup, the gold-plated conductive contacts have excellent conductivity and wear resistance, while the Pogo Pin spring pin has elastic telescopic properties. The two work together to achieve elastic contact when magnetically fixed, which can automatically offset the assembly error between the microphone body and the interface socket, ensuring stable electrical signal transmission and avoiding noise and signal interruption caused by poor contact.

[0009] As a preferred embodiment of this utility model, the bottom of the outer shell is fixedly connected with evenly distributed positioning blocks, and the silicone sealing gasket at the interface seat is provided with a positioning groove. The positioning blocks pass through the silicone sealing gasket at the outer shell and are inserted into the positioning groove.

[0010] This design allows the positioning block and positioning groove to be fitted together, serving a dual purpose of pre-positioning and preventing rotation. When assembling the microphone body and the interface base, the positioning block can be inserted into the positioning groove to quickly guide the two to align, improving assembly efficiency. After assembly, the engagement of the positioning block and positioning groove can restrict the circumferential rotation of the microphone body relative to the interface base, preventing the microphone body from rotating and causing misalignment of conductive terminals and displacement of silicone sealing gaskets when the equipment shakes, further ensuring connection stability and sealing.

[0011] In a preferred embodiment of this utility model, the limiting bending plate is fixedly connected to the side wall of the outer shell, the side wall of the interface seat is fixedly connected to an ear plate, a rotating rod is connected between the ear plates through a bearing, a support tube is fixedly connected to the rotating rod, the open end of the U-shaped clamp is inserted into the corresponding support tube, and the other end of the U-shaped clamp can be elastically stretched over the top of the limiting bending plate and reset to be locked into the inner side of the limiting bending plate.

[0012] This design creates a secondary fixing structure for the limiting component. After the magnetic iron plate provides initial fixation, the U-shaped locking rod, inserted into the inner side of the limiting bend plate, further restricts the axial separation of the microphone body and the interface seat. Even if the equipment is subjected to significant external force impact or shaking, it can prevent the magnetic joint from loosening and the microphone body from falling off. At the same time, the support tube can rotate around the rotating rod, and the U-shaped locking rod can be elastically stretched to adjust its length. During operation, simply pulling the U-shaped locking rod past the limiting bend plate is sufficient to complete the locking or separation without the need for special tools, thus balancing the reliability of the fixation with the convenience of disassembly and assembly.

[0013] In a preferred embodiment of this invention, the bottom of the opening end of the U-shaped clamp and the inner bottom of the support tube are fixedly connected by a support spring.

[0014] This design facilitates the elastic extension and retraction of the U-shaped lever.

[0015] As a preferred embodiment of this utility model, the side wall of the support tube is provided with a guide slide, and the side wall of the U-shaped clamp is fixedly connected with a guide slider, which slides along the guide slide.

[0016] This setting provides "directional guidance" for the telescopic movement of the U-shaped lever: it prevents the U-shaped lever from shifting or tilting during the stretching or compression process, ensuring that the U-shaped lever always moves along the axial direction of the support tube and accurately engages or disengages from the limiting bend.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: Significantly improved sealing performance: The tight fit of the double-layer silicone sealing gasket can effectively seal the seam between the microphone body and the interface seat, preventing external dust and moisture from entering the interior, while isolating external noise interference and improving the microphone's sound reception quality. Strong connection stability: The matching and engaging of the card slot and card protrusion, the magnetic attraction and fixation of the magnetic iron sheet, the anti-rotation cooperation of the positioning block and positioning groove, plus the secondary fixation of the limiting component, form a multi-layered fixing structure, which completely solves the problems of loose magnetic joints and microphone falling off during equipment carrying.

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] refer to Figures 1 to 6 As shown in the figure, this utility model provides a magnetically detachable microphone structure, including a device body 1 and a microphone body 2. The device body 1 includes an interface base 101 and a first conductive terminal 102 mounted on its end face. The microphone body 2 includes a housing 201 and a second conductive terminal 202. A slot 3 is formed on the end face of the microphone body 2. A protrusion 4 adapted to the slot 3 is fixedly mounted on the interface base 101. Magnetic iron pieces 7 are fixedly connected to the top of both the slot 3 and the protrusion 4. The magnetic iron pieces 7 are attracted and fixed to each other. Electrical terminal 202 passes through magnetic iron sheet 7 and latching protrusion 4 and is elastically connected to first conductive terminal 102. Silicone sealing gaskets 6 are fixedly connected to the interface seat 101 corresponding to the periphery of the latching protrusion 4 and the bottom of the outer shell 201. The silicone sealing gaskets 6 are tightly fitted together. Limiting members 8 are installed between the outer walls of the outer shell 201 and the interface seat 101 on both sides. The limiting member 8 includes a limiting bending plate 801 and a U-shaped locking rod 802. When the microphone body 2 and the interface seat 101 are magnetically fixed, the U-shaped locking rod 802 is inserted into the inner side of the limiting bending plate 801.

[0023] Specifically, the card protrusion 4 has a receiving hole 401, the first conductive terminal 102 is located at the receiving hole 401, and the second conductive terminal 202 extends into the receiving hole 401 and is elastically connected to the first conductive terminal 102. The first conductive terminal 102 is a gold-plated conductive contact, and the second conductive terminal 202 is a Pogo Pin spring pin.

[0024] Using the above solution, the gold-plated conductive contacts have excellent conductivity and wear resistance, and the Pogo Pin spring pin has elastic extension characteristics. The two work together to achieve elastic contact when magnetically fixed, which can automatically offset the assembly error between the microphone body 2 and the interface socket 101, ensuring stable electrical signal transmission and avoiding noise and signal interruption caused by poor contact.

[0025] Specifically, the bottom of the outer shell 201 is fixedly connected with evenly distributed positioning blocks 5, and the silicone sealing gasket 6 at the interface seat 101 is provided with a positioning groove 501. The positioning block 5 passes through the silicone sealing gasket 6 at the outer shell 201 and is inserted into the positioning groove 501.

[0026] Using the above scheme, the fitting and plugging of the positioning block 5 and the positioning groove 501 can play a dual role of pre-positioning and anti-rotation. When the microphone body 2 and the interface seat 101 are assembled, the positioning block 5 can be inserted into the positioning groove 501 to quickly guide the two to align, improving assembly efficiency. After assembly, the engagement of the positioning block 5 and the positioning groove 501 can restrict the circumferential rotation of the microphone body 2 relative to the interface seat 101, preventing the microphone body 2 from rotating and causing the conductive terminals to misalign and the silicone sealing gasket 6 to shift when the equipment shakes, further ensuring connection stability and sealing.

[0027] Specifically, the limiting bending plate 801 is fixedly connected to the side wall of the housing 201, the side wall of the interface seat 101 is fixedly connected to the ear plate 808, the ear plates 808 are connected to the rotating rod 807 through the bearing, the rotating rod 807 is fixedly connected to the support tube 805, the open end of the U-shaped clamp 802 is inserted into the corresponding support tube 805, and the other end of the U-shaped clamp 802 can be elastically stretched over the top of the limiting bending plate 801 and reset and clamped into the inner side of the limiting bending plate 801.

[0028] Using the above scheme, the limiting component 8 forms a secondary fixing structure. Based on the initial fixing achieved by the magnetic iron plate 7, the U-shaped clamp 802 can further restrict the axial separation of the microphone body 2 and the interface seat 101 by inserting into the inner side of the limiting bending plate 801. Even if the equipment is subjected to a large external force collision or shaking, it can prevent the magnetic joint from loosening and the microphone body 2 from falling off. At the same time, the support tube 805 can rotate around the rotating rod 807, and the U-shaped clamp 802 can be elastically stretched to adjust its length. During operation, simply pull the U-shaped clamp over the limiting bending plate 801 to complete the locking or separation without special tools, thus balancing the reliability of the fixation and the convenience of disassembly and assembly.

[0029] Specifically, the bottom of the open end of the U-shaped lever 802 and the inner bottom of the support tube 805 are fixedly connected by a support spring 804.

[0030] The above solution facilitates the elastic telescopic movement of the U-shaped lever 802.

[0031] Specifically, the side wall of the support tube 805 is provided with a guide slide 806, and the side wall of the U-shaped clamp 802 is fixedly connected with a guide slider 803, which slides along the guide slide 806.

[0032] The above solution provides "directional guidance" for the telescopic movement of the U-shaped lever: it prevents the U-shaped lever from shifting or tilting during the stretching or compression process, and ensures that the U-shaped lever always moves along the axial direction of the support tube 805, accurately engaging or disengaging from the limiting bend plate 801.

[0033] The working principle of this utility model: During use and assembly, the positioning block 5 is first precisely aligned with the positioning groove 501 on the silicone sealing gasket 6, guiding the slot 3 of the microphone body 2 into the protrusion 4 of the interface seat 101. The magnetic iron piece 7 on the top of the slot 3 and the protrusion 4 attract each other, achieving initial fixation. At the same time, the two sets of silicone sealing gaskets 6 are tightly fitted to form a seal. Then, the support tube 805 on the side wall of the interface seat 101 is rotated so that the U-shaped locking rod 802 is aligned with the limiting bending plate 801 on the side wall of the outer shell 201, and the U-shaped locking rod 802 is elastically stretched to pass over the top of the limiting bending plate 801. The support spring 804 returns to its original position and brings the U-shaped locking rod 802 into the inner side of the limiting bending plate 801, completing the secondary fixation and preventing axial separation.

[0034] Signal transmission: After fixing, the second conductive terminal 202 of the microphone body 2 extends into the receiving hole 401 of the card protrusion 4 and elastically abuts against the first conductive terminal 102 of the device interface seat 101; the electroacoustic conversion component inside the microphone body 2 converts the sound signal into an electrical signal, which is amplified and noise-reduced by the signal processing module, and then transmitted to the signal receiving module of the device body 1 through the stable contact between the Pogo Pin spring pin and the gold-plated conductive contact, thus realizing the effective transmission of the sound signal. This is existing technology and will not be elaborated further.

[0035] During disassembly, rotate and stretch the U-shaped lever 802 to disengage from the limiting bend plate 801, then gently pull the microphone body 2 to separate the slot 3 from the protrusion 4 and disengage the magnetic iron piece 7, thus removing the microphone body 2. The entire process requires no special tools and is easy to operate.
