Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, and specifically relates to a waterproof microphone assembly. Background Technology

[0002] Existing microphones exhibit significant structural sealing defects in humid or watery environments. Traditional products often rely on a single rubber ring or threaded compression seal at the shell joints. When faced with changes in moisture pressure, such as steam impacts in the kitchen or condensation due to temperature differences in the bathroom, gaps can easily appear due to aging of the seals or assembly errors, allowing moisture to penetrate the internal circuitry. Especially in detachable designs, it is difficult to balance sealing performance with ease of disassembly and assembly. Screw-based fastening is not only cumbersome, but repeated disassembly and assembly can also increase the risk of seal failure. On the other hand, some magnetic connection products, due to the separate design of the magnetic components and the sealing structure, often experience weak attraction due to a mismatch between magnetic force and sealing pressure, failing to guarantee long-term stable waterproofing. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof microphone assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof microphone assembly, comprising a main housing, a lower housing, and a base, wherein one end of the main housing is magnetically and detachably connected to the lower housing via an electrical connector, and the upper end of the main housing is provided with a microphone head with a waterproof layer;

[0005] The mating surface between the main housing and the lower housing is provided with a combined waterproof rubber ring with embedded magnetic blocks to achieve waterproof sealing after magnetic connection.

[0006] The base is connected to the bottom of the lower housing and is used to waterproof and seal the inner cavity port at the lower end of the lower housing.

[0007] Preferably, the lower housing has a square cavity inside, and the electrical connector is fixed to the upper end of the square cavity. Two pins are symmetrically arranged through the electrical connector. The structural constraint of the square cavity ensures that the electrical connector is installed in a precise position, and the symmetrical pin design improves the stability of the circuit connection and avoids poor contact.

[0008] Preferably, a square rechargeable battery pack is detachably installed at the bottom of the square cavity, and electrode charging slots are symmetrically provided at the ends of the rechargeable battery pack for connecting and engaging with the pins. The structural constraints of the square cavity ensure that the electrical connector is installed in a precise position, while the symmetrical pin design improves the stability of the circuit connection and avoids poor contact.

[0009] Preferably, the lower housing is provided with an annular combined rubber ring on its periphery, and metal blocks are uniformly embedded in the combined rubber ring, so that the combined rubber ring can be magnetically sealed with the combined waterproof rubber ring. The metal blocks and the magnetic blocks in the combined waterproof rubber ring form a magnetic attraction, so that the combined rubber ring and the rubber ring fit tightly together, which strengthens the sealing pressure of the housing joint surface and improves the waterproof effect.

[0010] Preferably, the lower surface of the main housing is provided with an annular waterproof combination groove, the combined waterproof rubber ring is placed in the waterproof combination groove, the magnetic block is evenly embedded in the combined waterproof rubber ring, the combined rubber ring is embedded in the waterproof combination groove, and a waterproof seal is formed by the magnetic block and the combined waterproof rubber ring. The waterproof combination groove provides positioning space for the sealing structure. The magnetic block and the metal block of the combined rubber ring attract each other, realizing the simultaneous completion of magnetic connection and sealing, taking into account both convenience and sealing performance.

[0011] Preferably, a power supply combination socket is embedded at the bottom of the main housing, and the power supply combination socket is connected to the electrical connector for electrical connection. The surface of the power supply combination socket is provided with electrode slots that cooperate with the plug pins.

[0012] Preferably, the electrical connector is located inside the main housing and electrically connected to a control motherboard that controls the operation of the microphone. The control motherboard integrates the control functions required for the operation of the microphone, and efficiently receives power and regulates various performance parameters through the electrical connector, thereby improving the overall coordination of the equipment operation.

[0013] Preferably, the base surface is provided with a cylindrical battery holder, and the surface of the battery holder is provided with a square groove for positioning the bottom of the charging battery pack. The outer surface of the battery holder is fitted with an elastic sealing ring to achieve a seal between the base and the lower housing. The square groove fixes the bottom of the battery and prevents shaking. The elastic sealing ring expands and seals when the base and the lower housing are connected, blocking the bottom moisture intrusion path.

[0014] Preferably, the microphone head has a spherical structure with a metal mesh cover on top and a waterproof and breathable membrane attached to the inside of the metal mesh cover. The spherical design optimizes the sound pickup angle, the metal mesh cover protects the internal components, and the waterproof and breathable membrane ensures sound transmission while blocking water vapor, thus avoiding sound quality distortion.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This utility model features a magnetic attraction and sealing synergistic design to solve the problem of weak attraction and sealing failure: the magnetic block is embedded in the combined waterproof rubber ring, and together with the combined rubber ring containing the metal block, the main shell and the lower shell are simultaneously sealed and pressed during the magnetic attraction connection process. The magnetic force and sealing pressure are precisely matched, which not only retains the convenience of magnetic attraction assembly and disassembly, but also avoids the sealing failure caused by weak attraction in the traditional separate design, thus achieving long-term stable waterproofing.

[0017] This utility model consists of a metal mesh cover and a waterproof and breathable membrane for composite protection at the head, a combination of rubber rings sealing the joint surface of the main shell and the lower shell, and a bottom sealing ring for the base, forming a three-dimensional waterproof barrier from the pickup end to the power supply end. It can effectively resist various forms of water vapor intrusion such as spray, steam, and condensation, breaking through the scene limitations of traditional microphones.

[0018] This utility model adopts a precise insertion structure for square battery packs, pins, and electrode slots. Combined with battery holder positioning and base sealing, it not only ensures convenient battery installation and removal but also blocks the channel for moisture to enter the battery compartment. This solves the problems of electrode oxidation and short circuits caused by gaps in traditional battery compartments, and extends the equipment's battery life.

[0019] The waterproof combination groove of this utility model provides a precise installation space for the sealing component. The square cavity constrains the relative position of the battery and the electrical connector. The elastic fit between the electrode slot and the pin enhances the stability of the circuit connection. This allows the sealing, power supply, control and other functional modules to work together through structural positioning, thereby improving overall reliability and assembly efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a waterproof microphone assembly, comprising:

[0031] The main housing 1, lower housing 2, and base 5 together form the main frame of the component. The main housing 1 is made of high-strength ABS engineering plastic, which is both lightweight and corrosion-resistant. One end of it is magnetically and detachably connected to the lower housing 2 via an electrical connector 8, and the upper end is equipped with a waterproof head 6. The head 6 is designed with a spherical structure, and the metal mesh cover 22 on the top is made of 304 stainless steel, which not only has good rust resistance but also effectively protects the internal components. The inside of the metal mesh cover 22 is tightly covered with a waterproof and breathable polytetrafluoroethylene membrane 21. The micropores of this membrane are only 0.1-0.3 micrometers in diameter, which can completely block water vapor while ensuring that the sound signal can pass through smoothly, avoiding sound quality distortion.

[0032] A combined waterproof rubber ring 4 is provided at the joint surface of the main shell 1 and the lower shell 2. The rubber ring is made of aging-resistant EPDM rubber, and neodymium iron boron magnetic blocks 3 are uniformly embedded inside. The magnetic blocks 3 are integrally molded with the rubber ring through injection molding to ensure a stable connection. An annular waterproof combination groove 15 is opened on the lower surface of the main shell 1, and the combined waterproof rubber ring 4 is embedded in the groove. Correspondingly, an annular combined rubber ring 12 is provided on the periphery of the lower shell 2. Its material is the same as that of the combined waterproof rubber ring 4, and iron-nickel alloy metal blocks 13 are uniformly embedded inside. When the main shell 1 and the lower shell 2 are connected, the combined rubber ring 12 is precisely embedded in the waterproof combination groove 15. The magnetic blocks 3 and the metal blocks 13 generate a strong magnetic attraction, so that the combined waterproof rubber ring 4 and the combined rubber ring 12 are tightly fitted to form an annular sealing strip, realizing the simultaneous completion of magnetic connection and waterproof sealing.

[0033] The lower housing 2 is injection molded from flame-retardant ABS material and has a square cavity 7 inside. The cavity walls are smoothed to reduce assembly resistance. The electrical connector 8 is made of high-temperature resistant nylon material and is fixed to the upper part of the square cavity 7 with screws. Two brass pins 9 are symmetrically inserted through its surface. The surface of the pins 9 is nickel-plated to enhance conductivity and corrosion resistance. A square rechargeable battery pack 10 is retractable at the bottom of the square cavity 7. The battery pack shell is made of polycarbonate material, and the ends are symmetrically provided with electrode charging slots 11 that match the pins 9. The slots have gold-plated contacts to ensure conductivity stability when connected to the pins 9.

[0034] The bottom of the main housing 1 is embedded with a power supply combination socket 16 made of LCP liquid crystal polymer material. Its surface has electrode slots 17 that precisely match the pins 9. The inner wall of the slot is designed with elastic copper sheet to tightly wrap the pins 9, ensuring reliable circuit conduction and buffering the impact force during assembly. The electrical connector 8 is located inside the main housing 1 and is connected to the control motherboard 14 via a ribbon cable. The motherboard is encapsulated with epoxy resin, which has waterproof and moisture-proof performance, and can stably adjust the microphone's pickup sensitivity, signal transmission and other core functions.

[0035] The base 5 is made of food-grade silicone and hard plastic composite material, with a cylindrical battery holder 18 integrally molded on its surface. A square groove 19 is formed on the surface of the battery holder 18, and a silicone anti-slip pad is installed inside the groove to provide stable positioning for the bottom of the rechargeable battery pack 10, preventing battery displacement due to vibration during use. A silicone elastic sealing ring 20 is fitted around the outer surface of the battery holder 18. This sealing ring has a trapezoidal cross-section. When the base 5 is screwed to the bottom of the lower housing 2, the sealing ring expands radially under axial pressure, tightly fitting against the inner wall of the lower housing 2 to form an absolute seal, completely blocking the path of moisture intrusion from the bottom.

[0036] Specifically, during initial assembly and startup: First, check that all components are installed correctly: Confirm that the square rechargeable battery pack 10 is correctly placed into the square cavity 7 of the lower housing 2, and that the electrode charging slot 11 at its end is precisely connected to the pin 9 of the electrical connector 8. The base 5 is sealed to the bottom of the lower housing 2 through the spring-loaded sealing ring 20. Then, align the waterproof combination slot 15 at the lower end of the main housing 1 with the combination rubber ring 12 of the lower housing 2, and gently push the main housing 1. Utilize the magnetic attraction between the magnetic block 3 inside the combination waterproof rubber ring 4 and the metal block 13 inside the combination rubber ring 12 to make the two fit tightly together. At the same time, the pin 9 of the electrical connector 8 is inserted into the electrode slot 17 of the main housing 1, completing the circuit conduction. At this time, the control motherboard 14 receives power from the battery pack, the microphone is activated, and the metal mesh cover 22 of the microphone head 6, together with the inner waterproof and breathable membrane 21, can pick up sound normally in environments such as kitchen steam and bathroom water mist. The waterproof and breathable membrane 21 blocks water vapor while ensuring lossless transmission of sound signals.

[0037] Routine Use and Maintenance: During use, the magnetically connected main housing and lower housing 2 require no additional fixing and can be used directly by hand or placed on a stand. If the pickup angle needs adjustment, the spherical microphone head 6 can rotate freely. The 304 stainless steel metal mesh cover 22 can be directly washed with water to remove surface oil; simply wipe it dry after washing. The control motherboard 14 uses a built-in program to stably regulate parameters such as volume and sensitivity, ensuring continuous operation even in humid environments.

[0038] When charging is required, there is no need to remove the rechargeable battery pack 10 from the cavity in the lower housing 2. It can be charged using an external charger with a charging slot. This allows the rechargeable battery pack 10 to be used until the output power and storage capacity decrease before replacement. The rechargeable battery pack 10 can be removed from the inner cavity of the lower housing 2 simply by removing the base 5 from the bottom. In order to ensure the waterproof sealing of the microphone's plug-in power supply connection, the rechargeable battery pack 10 can be removed separately for charging. The main housing 1 has a switch component on the surface for turning the microphone on and off.

[0039] Specific process of disassembling and replacing batteries

[0040] Separating the main housing 1 from the lower housing 2: Hold the lower housing 2 with one hand and the main housing 1 with the other, apply an outward pulling force along the axial direction to overcome the attraction force between the magnetic block 3 and the metal block 13, thus separating the main housing 1 from the lower housing 2. At this time, the combined rubber ring 12 comes out of the waterproof combined groove 15, the pin 9 is disconnected from the electrode slot 17, and the upper structure of the square cavity 7 of the lower housing 2 is exposed.

[0041] To remove the base 5 and the old battery: Rotate the base 5 (if it is threaded) or press the latch (if it is latched) to separate the base 5 from the bottom of the lower housing 2. The spring-loaded sealing ring 20 will then detach from the port of the lower housing 2 along with the base 5. At this point, the square rechargeable battery pack 10 at the bottom of the square cavity 7 will lose its bottom limit. Pull the battery pack directly upwards along the inner wall of the square cavity 7, being careful to avoid pulling on the connection between the electrode charging slot 11 and the pin 9 (if the battery pack is stuck, gently shake the lower housing 2 to assist in removal).

[0042] The inner two side walls of the square cavity 7 are provided with sheet-like thermal grease, and one side of the thermal grease is provided with a heat dissipation aluminum plate that is attached to both sides of the rechargeable battery pack 10. The setting of the heat dissipation aluminum plate does not affect the disassembly and assembly of the rechargeable battery pack 10.

[0043] Installing the new battery and resetting the base 5: Take a new square rechargeable battery pack 10, align the electrode charging slot 11 at its end with the pin 9 of the electrical connector 8, and slowly push it in along the inner wall of the square cavity 7 to the bottom, ensuring that the battery pack is fully embedded and not loose. Then align the battery holder 18 of the base 5 with the bottom port of the lower housing 2, fit the square fixing slot 19 into the bottom of the battery pack, press the base 5 to make the spring-loaded sealing ring 20 make tight contact with the port of the lower housing 2, rotate or fasten the base 5 to the locked state, at which time the sealing ring is compressed and expanded, completing the bottom seal.

[0044] Reconnect the main housing 1: Align the waterproof combination groove 15 of the main housing 1 with the combination rubber ring 12 of the lower housing 2 again, and gently push the main housing 1 until it is magnetically attracted. Confirm that the pin 9 is fully inserted into the electrode slot 17. At this time, the microphone is powered back and can be used normally.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
