[0041] In order to make the purpose, technical solution and advantages of the utility model more obvious, the exemplary embodiments according to the utility model will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments of the utility model, and it should be understood that the utility model is not limited to the exemplary embodiments described here. Based on the embodiments of the utility model described in the utility model, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the utility model.

[0042] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0043] It should be understood that the utility model can be implemented in different forms and should not be interpreted as being limited to the embodiments proposed herein. On the contrary, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.

[0044] In order to thoroughly understand the present invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by the present invention. The optional embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0045] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0046] In the related art, the charging device of the microphone mainly includes a charging seat and a fixing frame of separate design. The fixing frame is provided with a placement groove, which is used to accommodate and support the microphone. The charging seat is provided with a contact platform, and when the bottom of the microphone contacts the contact platform, the charging seat is suitable for charging the microphone. The fixing frame is provided with a first docking portion for docking with the charging seat, and the charging seat is provided with a second docking portion corresponding to the first docking portion. The first docking portion and the second docking portion are both provided with fastening holes, and the fasteners pass through the fastening holes on the first docking portion and the fastening holes on the second docking portion in sequence to fix the fixing frame and the charging seat. Since the charging seat and the fixing frame are designed separately, they are assembled together through the fastening holes and fasteners on the two docking portions. During the manufacturing process of the charging seat and the fixing frame, there is a manufacturing tolerance in the position of the fastening hole; during the assembly process, there is also an assembly tolerance between the fastener and the fastening hole. If the manufacturing tolerance and the assembly tolerance are too large, it will cause the electrode terminal at the bottom of the microphone to fail to reliably and stably abut against the electrode terminal of the contact platform, resulting in the failure of reliable and stable charging between the microphone and the charging seat. In order to solve this technical problem, the present application provides the following technical solution.

[0047] The present application embodiment provides a charging device for a microphone, referring to Figure 1 to Figure 6 The charging device includes: an integrally formed tube body 10 and a base 20; wherein the tube body 10 is used to accommodate a microphone 40, the base 20 is located at one end of the tube body 10, and the base 20 and / or the tube body 10 is used to be electrically connected to the microphone 40.

[0048] In the above scheme, by providing an integrally formed tube body 10 and base 20, there is no need to assemble the base 20 and the tube body 10, thereby avoiding the assembly tolerance between the base 20 and the tube body 10. When at least part of the microphone 40 is placed in the accommodating cavity 11, the microphone 40 and the charging device can be reliably and stably electrically connected, so that the charging device can reliably and stably charge the microphone 40. The above structures are described in detail below in conjunction with the accompanying drawings.

[0049] When setting the tube body 10 and the base 20, refer to Figure 1 and Figure 3, the tube body 10 and the base 20 are prepared by an integrated molding process, that is, the tube body 10 and the base 20 are formed together by an integrated connection, and there is no need to use fasteners such as but not limited to screw connection, clamping, bonding, etc. to connect them together. The integrated molding process can use processes such as but not limited to integrated injection molding, so that the obtained tube body 10 and base 20 are both insulating plastic structures. Since there is no need to assemble between the tube body 10 and the base 20, the assembly tolerance between the base 20 and the tube body 10 is avoided. When at least part of the microphone 40 is placed in the tube body 10, the microphone 40 can be reliably and stably electrically connected to the charging device, so that the charging device can reliably and stably charge the microphone 40. That is, by adopting an integrated solution of the tube body 10 and the base 20, the influence of the dimensional tolerance problem of the base 20 and the tube body 10 on the accurate docking performance of the electrode terminals of the charging device can be avoided.

[0050] Regarding the structure of the tube body 10, refer to Figure 1 and Figure 3 , which has a first end and a second end in relative positions, wherein the base 20 is located at one end of the tube body 10, and illustratively, the base 20 can be located at the first end of the tube body 10. The tube body 10 is used to accommodate the microphone 40. illustratively, the tube body 10 can have a housing 11 for accommodating the microphone 40. The housing 11 is connected to the tube mouth 14 at the second end of the tube body 10, so that the microphone 40 is partially or completely placed in the housing 11 of the tube body 10 from the position of the tube mouth 14, so that the tube body 10 can limit the microphone 40 to the left and right, and prevent the microphone 40 from shaking left and right during the charging process, so as to ensure that the electrode terminals on the microphone 40 can reliably and stably abut against the electrode terminals on the base 20 and / or the tube body 10, so that the electrode terminals on the microphone 40 are reliably and stably electrically connected to the electrode terminals on the base 20 and / or the tube body 10, so that the charging device can reliably and stably charge the microphone 40. illustratively, the electrode terminals can be set only on the base 20, so that the base 20 is used to be electrically connected to the microphone 40. Exemplarily, electrode terminals may be provided only on the tube body 10 so that the tube body 10 is electrically connected to the microphone 40. Exemplarily, electrode terminals may be provided on both the base 20 and the tube body 10 so that both the tube body 10 and the base 20 are electrically connected to the microphone 40.

[0051] The shape of the tube body 10 can be any tube shape, specifically matched with the shape of the microphone 40. For example, when the cross-sectional shape of the microphone 40 is cylindrical, the cross-sectional shape of the tube body 10 can also be cylindrical. When the cross-sectional shape of the microphone 40 is rectangular, the cross-sectional shape of the tube body 10 can also be rectangular. Thus, the microphone 40 can be at least partially placed in the tube body 10.

[0052] Exemplary, reference Figure 1 to Figure 6 , the base 20 and / or the tube body 10 are provided with an electrode mounting hole 21, and the electrode mounting hole 21 faces the accommodating cavity 11 of the tube body 10. By providing the electrode mounting hole 21 on the base 20 and / or the tube body 10, the specific position of the electrode terminal on the base 20 and / or the tube body 10 can be determined, so that the electrode terminal on the microphone 40 and the electrode terminal on the base 20 and / or the tube body 10 can be reliably and stably electrically connected. Specifically, the electrode mounting hole 21 can be provided only on the base 20; the electrode mounting hole 21 can also be provided only on the tube body 10; or the electrode mounting hole 21 can be provided on both the base 20 and the tube body 10. It is related to the specific setting position of the electrode terminal.

[0053] Exemplarily, the charging device may further include: a first terminal, which is mounted in the electrode mounting hole 21 and faces the accommodating cavity 11; wherein the first terminal is used to be electrically connected to the microphone 40. That is, when at least part of the microphone 40 is placed in the accommodating cavity 11, the microphone 40 is electrically connected to the first terminal, thereby realizing the electrical connection between the charging device and the microphone 40. There are many ways to set the first terminal.

[0054] Exemplary, reference Figure 1 to Figure 6 , the first terminal includes a first electrode terminal 23 and a second electrode terminal 24. Exemplarily, one of the first electrode terminal 23 and the second electrode terminal 24 may be a positive electrode terminal, and the other electrode terminal may be a negative electrode terminal. For example, the first electrode terminal 23 may be a positive electrode terminal, and the second electrode terminal 24 may be a negative electrode terminal; or, the first electrode terminal 23 may be a negative electrode terminal, and the second electrode terminal 24 may be a positive electrode terminal.

[0055] When determining the location of the first electrode terminal 23 and the second electrode terminal 24, a variety of methods can be used. Exemplarily, the first electrode terminal 23 is disposed on the axis of the base 20 and faces the accommodating cavity 11. The second electrode terminal 24 is disposed around the axis of the tube body 10. When this arrangement is adopted, when the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, there is no need to pay attention to the direction of the microphone 40.

[0056] At this time, the second electrode terminal 24 can also be arranged in a variety of ways. For example, refer to Figure 2 , Figure 3 and Figure 4 , the second electrode terminal 24 can be arranged on the base 20 and facing the accommodating cavity 11, that is, at this time, the first electrode terminal 23 and the second electrode terminal 24 are both arranged on the base 20. And / or, the second electrode terminal 24 is arranged on the inner wall of the tube body 10 and faces the accommodating cavity 11, at this time, the first electrode terminal 23 is arranged on the base 20, and at this time, the second electrode terminal 24 is arranged on the tube body 10.

[0057] When setting the base 20, refer to Figure 2 , Figure 3 and Figure 4 , illustratively, an electrode mounting hole 21 is provided on the base 20, and the electrode mounting hole 21 is communicated with the tube body 10. A first terminal is provided at the electrode mounting hole 21, and the first terminal faces the accommodating cavity 11 of the tube body 10, and the first terminal is used to abut against the second terminal at the bottom of the microphone 40. When at least part of the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, the second terminal at the bottom of the microphone 40 can abut against the first terminal at the electrode mounting hole 21, so that a reliable and stable electrical connection can be made between the first terminal and the second terminal.

[0058] When setting the electrode mounting hole 21 and the first terminal, various methods can be used. For example, refer to Figure 2 , Figure 3 and Figure 4 The electrode mounting hole 21 at least includes a positive electrode mounting hole and a negative electrode mounting hole. The first terminal at least includes a first electrode terminal 23 and a second electrode terminal 24, wherein the first electrode terminal 23 is assembled in the positive electrode mounting hole, the second electrode terminal 24 is assembled in the negative electrode mounting hole, and the first electrode terminal 23 and the second electrode terminal 24 are insulated and separated.

[0059] refer to Figures 2 to 7 The number and position of the electrode mounting holes 21 and the first terminals need to match the setting of the second terminals on the microphone 40 to ensure that when the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, the second terminal at the bottom of the microphone 40 can abut against the corresponding first terminal.

[0060] Exemplary, reference Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the second terminal may include: a third electrode terminal 41 and a fourth electrode terminal 42. Among them, illustratively, one of the third electrode terminal 41 and the fourth electrode terminal 42 may be a positive terminal, and the other electrode terminal may be a negative terminal. Exemplarily, the third electrode terminal 41 is used to abut against the first electrode terminal 23, and the fourth electrode terminal 44 is used to abut against the second electrode terminal 24. Exemplarily, the third electrode terminal 41 may be a positive terminal, and the fourth electrode terminal 42 may be a negative terminal. In this case, the first electrode terminal 23 may be a positive terminal, and the second electrode terminal 24 may be a negative terminal. Exemplarily, the third electrode terminal 41 may be a negative terminal, and the fourth electrode terminal 42 may be a positive terminal. In this case, the first electrode terminal 23 may be a negative terminal, and the second electrode terminal 24 may be a positive terminal.

[0061] Exemplarily, the third electrode terminal 41 is disposed on the axis of the bottom of the microphone 40, and the fourth electrode terminal 42 is disposed in a ring shape around the third electrode terminal 41. In this case, the fourth electrode terminal 42 can be disposed at the bottom of the microphone 40; the first electrode terminal 23 can be disposed on the axis of the base 20, matching the third electrode terminal 41. Of course, in other embodiments, the fourth electrode terminal 42 can be disposed on the side wall of the microphone 40; the second electrode terminal 24 can be located on the inner wall of the tube body 10, matching the fourth electrode terminal 42.

[0062] Exemplary, reference Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , when the third electrode terminal 41 is arranged on the axis of the bottom of the microphone 40, the fourth electrode terminal 42 is arranged on the bottom of the microphone 40, the first electrode terminal 23 is arranged on the axis of the base 20, and the second electrode terminal is arranged on the base 20, when at least part of the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, the third electrode terminal 41 at the bottom of the microphone 40 can abut against the first electrode terminal 23, and the fourth electrode terminal 42 at the bottom of the microphone 40 can abut against the second electrode terminal 24, so that a reliable and stable electrical connection can be made between the first terminal and the second terminal. And when this arrangement is adopted, when the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, there is no need to pay attention to the direction of the microphone 40.

[0063] Exemplarily, the number of the first electrode terminal 23 and the positive electrode mounting hole can be one, the number of the second electrode terminal 24 and the negative electrode mounting hole can be two, and the two negative electrode mounting holes are located on both sides of one positive electrode mounting hole. Exemplarily, the positive electrode mounting hole can be located at the center of the tube body 10, so that the first electrode terminal 23 can be assembled at the center of the tube body 10. The two negative electrode mounting holes can be arranged on both sides of the positive electrode mounting hole, so that the two second electrode terminals 24 are arranged between the first electrode terminals 23. Therefore, when the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, there is no need to pay attention to the direction of the microphone 40.

[0064] For example, the first terminal may use a pin connector such as but not limited to a Pogopin to simplify the arrangement of the electrode terminal. For example, the first electrode terminal 23 may be a pin connector, and the second electrode terminal 24 may be two pin connectors, which are respectively arranged on both sides of the first electrode terminal 23.

[0065] When setting the second terminal on the microphone 40, various methods can be used. For example, refer to Figure 5 , Figure 6 and Figure 7, the second terminal at least includes a third electrode terminal 41 and a fourth electrode terminal 42, and the third electrode terminal 41 and the fourth electrode terminal 42 are insulated and separated. Exemplarily, the second terminal can be set at the bottom of the microphone 40. Exemplarily, the third electrode terminal 41 can be a contact located at the bottom of the microphone 40, and the third electrode terminal 41 can be located at the center of the bottom of the microphone 40, that is, the third electrode terminal 41 is located on the axis of the bottom of the microphone 40. The fourth electrode terminal 42 can be an annular metal conductive sheet, and the third electrode terminal 41 is located inside the fourth electrode terminal 42 and is insulated and separated from the fourth electrode terminal 42 by an insulating ring. It should be explained that the bottom of the microphone 40 refers to: the end position of the microphone 40 opposite to the microphone head. When the microphone 40 is placed in the tube body 10, the bottom of the microphone 40 is opposite to the base 20, and the third electrode terminal 41 on the microphone 40 abuts on the first electrode terminal 23 of the base 20, and the fourth electrode terminal 42 on the microphone 40 abuts on the second electrode terminal 24 of the base 20. Exemplarily, the second terminal may be a conductive sheet or a conductive ring to simplify the setting of the electrode terminal. Exemplarily, the third electrode terminal 41 may be a conductive sheet, which is arranged at the center of the bottom of the microphone 40 and matches the position of the first electrode terminal 23 on the charging device. The fourth electrode terminal 42 may be a conductive ring, and the third electrode terminal 41 is located inside the conductive ring and is insulated and separated by an insulating ring. The material of the conductive sheet or the conductive ring may be a structure such as but not limited to a copper sheet, an aluminum sheet, etc. Exemplarily, a battery is arranged inside the microphone 40, and the battery is connected to the second terminal, so that the charging device can charge the battery inside the microphone 40 through the second terminal.

[0066] Exemplary, reference Figure 3 and Figure 4 , a receiving cavity 26 may be provided on the side of the base 20 facing away from the tube body 10, a circuit board is provided in the receiving cavity 26, and the first terminal is electrically connected to the circuit board. Circuit structures such as but not limited to a DC-DC converter and a filter circuit may be provided on the circuit board, so that it can be connected to an external power supply and input electrical energy to the first terminal.

Exemplarily, a wiring harness connector may be provided on the cover plate 27, the wiring harness connector is electrically connected to the circuit board, and the wiring harness connector is used to plug and connect with an external power supply line, thereby facilitating the electrical connection between the charging device and the external power supply line.

[0067] For example, the wiring harness connector can be used as follows Figure 8The wiring harness connector is shown. Pin number 1 on the wiring harness connector is used to connect the negative ground of the power supply, and pin number 3 on the wiring harness connector is used to connect the positive terminal of the power supply. Fig. 9 The power source may be a battery pack, a power chip or the like on the vehicle. The current in the vehicle is introduced into the base 20 of the charging device through the wiring harness connector. The pin definition of the wiring harness connector is shown in Table 1 below.

[0070] Exemplary, reference Figure 1 and Figure 2 , an elastic protrusion 12 may be provided in the accommodating cavity 11 of the tube body 10, that is, the elastic protrusion 12 is located on the cavity wall of the accommodating cavity 11 of the tube body 10. The elastic protrusion 12 is used to flexibly limit the position of the microphone 40. Exemplarily, the elastic protrusion 12 is used to press against the side wall of the microphone 40 to flexibly limit the position of the microphone 40. That is, the elastic protrusion 12 is configured as follows: when at least part of the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, the elastic protrusion 12 presses against the side wall of the microphone 40 to flexibly limit the position of the microphone 40. When the microphone 40 is placed in the tube body 10, the side wall of the microphone 40 is not in direct contact with the cavity wall of the accommodating cavity 11 of the tube body 10, but is separated by the elastic protrusion 12, and the elastic protrusion 12 can be pressed against the side wall of the microphone 40, so that the elastic protrusion 12 and the side wall of the microphone 40 have an interference fit extrusion force, preventing the microphone 40 from shaking left and right in the accommodating cavity 11 of the tube body 10, improving the reliability and stability of the electrical connection between the second terminal on the microphone 40 and the first terminal on the base 20, so that the charging device can reliably and stably charge the microphone 40. Regarding the material of the elastic protrusion 12, elastic materials such as but not limited to rubber, soft glue, etc. can be used. Exemplarily, the material of the elastic protrusion 12 can be selected from materials with aging resistance and corrosion resistance to improve the life of the elastic protrusion 12.

[0071] Exemplarily, the number of the elastic protrusions 12 may be at least two, and each elastic protrusion 12 is disposed at the cavity wall of the accommodating cavity 11 away from the base 20, that is, each elastic protrusion 12 is disposed at the cavity wall of the accommodating cavity 11 close to the second end, and each elastic protrusion 12 is disposed at the tube mouth 14 close to the second end of the tube body 10. At least two elastic protrusions 12 are circumferentially distributed around the axis of the tube body 10. That is, the number of the elastic protrusions 12 is two, three, four, five, six or more, and the plurality of elastic protrusions 12 are circumferentially distributed around the axis of the tube body 10. Exemplarily, the plurality of elastic protrusions 12 may be uniformly distributed circumferentially around the axis of the tube body 10 so that the spacing between two adjacent elastic protrusions 12 is equal, thereby reliably and stably fixing the microphone 40 at the center position of the tube body 10. It should be explained that the axis of the tube body 10 refers to: a line formed by connecting the centers of each cross section of the tube body 10. The circumferential direction of the tube body 10 refers to the circumferential direction formed along the outer circumference of the cross section on each cross section of the tube body 10. Exemplarily, the elastic protrusion 12 can be arranged at the cavity wall of the accommodating cavity 11 close to the second end. Of course, in other embodiments, the elastic protrusion 12 can also be arranged at a non-tube mouth position of the accommodating cavity 11 of the tube body 10. The material of the elastic protrusion 12 can be any elastic material, such as rubber, soft glue and the like.

Exemplarily, when the microphone 40 is placed in the tube body 10, the elastic ring 13 can have a certain degree of extrusion force between the side wall of the microphone 40. Of course, the extrusion force cannot be too large, so as to prevent the second terminal at the bottom of the microphone 40 from being unable to abut against the first terminal of the base 20. In some embodiments, the elastic ring 13 and the elastic protrusion 12 are an integral elastic member, and the elastic protrusion 12 and the elastic ring 13 can be obtained by integral molding, that is, the elastic protrusion 12 is a protrusion structure formed by integral molding on the inner wall of the elastic ring 13. Of course, in other embodiments, the elastic protrusion 12 can be provided separately from the elastic ring 13, and then assembled together by bonding, fastening with fasteners, etc. The material of the elastic ring 13 can be any elastic material, such as rubber, soft glue, etc. By disposing an elastic ring 13 at the tube opening 14 of the second end of the tube body 10 , the microphone 40 can be further fixed and the collision between the tube wall of the tube body 10 and the microphone 40 can be mitigated.

When the microphone 40 is placed in the tube body 10, the second annular magnetic component 43 at the bottom of the microphone 40 can be attracted together with the first annular magnetic component 25 on the base 20. In addition to the pressure of the second terminal abutting against the first terminal due to the gravity of the microphone 40 itself, the suction force generated by the two annular magnetic components is also increased, so that the second terminal can be reliably and stably abutted against the first terminal, thereby improving the reliability and stability of the electrical connection between the second terminal and the first terminal.

By providing the mounting portion 30, it is convenient to assemble the charging device on the external support.

The first mounting hole 31 is used to connect with the second mounting hole on the external support member through a fastener. The positioning hole 32 is configured as follows: when the positioning hole 32 is sleeved on the positioning protrusion on the support member, the first mounting hole 31 is aligned with the second mounting hole. Exemplarily, the mounting portion 30 can be an edge plate extending from the outer wall of the tube body 10, and the mounting portion 30 can be prepared with the tube body 10 by an integral molding process, so that the mounting portion 30 does not need to be connected with other connecting members. The first mounting hole 31 is provided on the mounting portion 30, and the second mounting hole is provided on the external support member, and the first mounting hole 31 cooperates with the second mounting hole, so that the first mounting hole 31 and the second mounting hole can be connected together by a fastener, thereby fixing the charging device on the external support member.

The base 20 of the charging device may include an elastic protrusion 12 and an elastic ring 13 located at the position of the pipe mouth 14, a plastic tube body 10, a PCB board, a first terminal, and a wiring harness connector. Exemplarily, the elastic protrusion 12 and the elastic ring 13 can further fix the microphone 40 and reduce the collision between the tube wall of the tube body 10 and the microphone 40. The plastic tube body 10 is lengthened and fixed to a support such as a vehicle by four-hole screws. The first mounting hole 31 is fixed by screws, and the positioning hole 32 is a limit to prevent fooling. The integrated solution of the tube body 10 and the base 20 can avoid the impact of the dimensional tolerance problem of the base 20 and the tube body 10 of the charging device on the product performance of the charging device. In some embodiments, the first terminal may include three pins disposed on the base 20, and the second terminal at the bottom of the microphone 40 is contacted by the pins to charge the battery inside the microphone 40. The current in the vehicle is introduced into the base 20 of the charging device through the wiring harness connector. Through the above technical solution, the charging device and the microphone 40 can be firmly fixed on the vehicle, and will not shake or fall off during the driving of the vehicle, and will not make abnormal noises.

[0082] In some embodiments, the microphone 40 can have a built-in rechargeable battery and a second annular magnetic part 43. When the microphone 40 is placed on the base 20 of the magnetic Pogopin charging device, the base 20Pin pin of the magnetic Pogopin charging device is connected to the metal steel sheet contact at the bottom of the microphone 40. The microphone 40 can be strongly attached to the base 20Pin pin by magnetic attraction and is not easy to fall off, thereby ensuring continuous and stable power supply to the microphone 40 and improving the charging stability of the microphone 40.

[0083] In the various embodiments shown above, by providing an integrally formed tube body 10 and base 20, there is no need to assemble the base 20 and the tube body 10, thereby avoiding assembly tolerances between the base 20 and the tube body 10. When at least a portion of the microphone 40 is placed in the tube body 10, the second terminal on the microphone 40 can reliably and stably abut against the first terminal on the base 20, so that a reliable and stable electrical connection is established between the second terminal and the first terminal, so that the charging device can reliably and stably charge the microphone 40.

[0085] (1) A long tube body 10 is used, and an elastic protrusion 12 and an elastic ring 13 are set on the cavity wall of the second end of the accommodating cavity 11. The four-hole screw fixation allows the base 20 and the microphone 40 of the charging device to be firmly fixed on the vehicle. During the driving of the vehicle, they will not shake or fall off, and there will be no abnormal noise.

[0086] (2) The integrated solution of the tube body 10 and the base 20 avoids the problem of out-of-tolerance size of the base 20 and the tube body 10 of the charging device, thereby ensuring the performance of the charging device.

[0087] (3) The magnetic Pogopin charging method has the following advantages over the traditional charging interface: 1) The microphone 40 can be strongly attached to the base 20 through magnetic attraction, automatically adsorbed, self-locking and interactive, and continuously and stably charge the microphone 40; 2) When separated by external force, it can automatically disconnect without damaging the connection port and the device; 3) It can withstand vibration and impact; 4) It can transmit large current and charge faster; 5) It has a long lifespan of up to 100,000 times; 6) It is waterproof and dustproof, up to IP2.

[0088] In addition, the present application also provides a microphone assembly, referring to Figures 1 to 9 The microphone assembly includes: a microphone 40 and a charging device for any one of the above-mentioned microphones 40.

[0089] Exemplarily, the tube body 10 has a receiving cavity 11 for receiving the microphone 40. Exemplarily, the receiving cavity 11 is used to receive the center of gravity of the microphone 40. That is, when the microphone 40 is placed in the tube body 10, the center of gravity of the microphone 40 is flush with the tube mouth 14 at the second end of the tube body 10, or is located in the receiving cavity 11 of the tube body 10. The above configuration can be achieved by determining the position of the center of gravity of the receiving cavity 11 and the microphone 40. Exemplarily, the depth of the receiving cavity 11 is H1, and the distance between the bottom of the microphone 40 and the center of gravity of the microphone 40 is H2, then H1≥H2. When determining the depth of the receiving cavity 11 of the tube body 10, refer to Figure 3 , the depth of the accommodating cavity 11 of the tube body 10 can be defined as H1. It should be explained that the depth direction of the accommodating cavity 11 is the axial direction of the tube body 10. At this time, refer to Figure 5, the distance between the bottom of the microphone 40 and the center of gravity O of the microphone 40 can be defined as H2, then H1 and H2 can satisfy the relationship: H1≥H2, that is, H1 is greater than or equal to H2, so that when the microphone 40 is placed in the tube body 10, the center of gravity of the microphone 40 is flush with the tube mouth 14 of the second end of the tube body 10, or is located in the accommodating cavity 11 of the tube body 10, so that even when applied to an environment such as a vehicle, no matter how large the instantaneous acceleration of the vehicle is, it can ensure that the microphone 40 is fixed in the tube body 10 and is not thrown out, ensuring a stable electrical connection between the electrode terminals on the charging device and the electrode terminals on the microphone 40, thereby ensuring that the microphone 40 does not shake during the driving of the vehicle and continuously and stably charges.

[0090] Exemplary, reference Figure 2 ,as well as Figures 4 to 7 , the tube body 10 has a receiving cavity 11 for accommodating the microphone 40, and the charging device may further include: a first terminal. Exemplarily, an electrode mounting hole 21 is provided on the base 20 and / or the tube body 10, and the electrode mounting hole 21 faces the receiving cavity 11. At this time, the first terminal is assembled in the electrode mounting hole 21 and faces the receiving cavity 11. At this time, a second terminal may be provided on the microphone 40. When at least part of the microphone 40 is placed in the receiving cavity 11, the first terminal abuts against the second terminal, so that the charging device is electrically connected to the microphone 40.

[0091] refer to Figures 2 to 7 The number and position of the electrode mounting holes 21 and the first terminals need to match the second terminal on the microphone 40, ensuring that the second terminal of the microphone 40 can abut against the corresponding first terminal when the microphone 40 is placed in the accommodating cavity 11 of the tube body 10. Exemplarily, when the first terminal is provided on the base 20, the second terminal can be provided at the bottom of the microphone 40; Exemplarily, when the first terminal is provided on the inner wall of the tube body 10, the second terminal can be provided on the side wall of the microphone 40.

[0092] Exemplary, reference Figure 2 ,as well as Figures 4 to 7, the second terminal may include: a third electrode terminal 41 and a fourth electrode terminal 42. Exemplarily, one of the third electrode terminal 41 and the fourth electrode terminal 42 may be a positive terminal, and the other electrode terminal may be a negative terminal. Exemplarily, the third electrode terminal 41 is used to abut against the first electrode terminal 23, and the fourth electrode terminal 42 is used to abut against the second electrode terminal 24. Exemplarily, the third electrode terminal 41 may be a positive terminal, and the fourth electrode terminal 42 may be a negative terminal. In this case, the first electrode terminal 23 may be a positive terminal, and the second electrode terminal 24 may be a negative terminal. Exemplarily, the third electrode terminal 41 may be a negative terminal, and the fourth electrode terminal 42 may be a positive terminal. In this case, the first electrode terminal 23 may be a negative terminal, and the second electrode terminal 24 may be a positive terminal.

[0093] Exemplarily, the third electrode terminal 41 can be arranged on the axis of the bottom of the microphone 40, and the fourth electrode terminal 42 is arranged in a ring shape around the third electrode terminal 41. In this case, the first electrode terminal 23 can be located in the middle of the base 20, matching with the third electrode terminal 41. The second electrode terminal 24 can be located on the edge of the base 20 or on the inner wall of the tube body 10, matching with the fourth electrode terminal 42. That is, the fourth electrode terminal 42 is arranged at the bottom of the microphone 40, and / or, the fourth electrode terminal 42 is arranged on the side wall of the microphone 40, which is specifically related to the setting position of the second electrode terminal 24.

[0094] Exemplarily, the third electrode terminal 41 can be arranged on the axis of the bottom of the microphone 40, and the second electrode terminal 24 can be located on the edge of the base 20. When at least part of the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, the third electrode terminal 41 at the bottom of the microphone 40 can abut against the first electrode terminal 23, and the fourth electrode terminal 42 at the bottom of the microphone 40 can abut against the second electrode terminal 24, so that a reliable and stable electrical connection can be made between the first terminal and the second terminal. And when this arrangement is adopted, when the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, there is no need to pay attention to the direction of the microphone 40.

[0095] Exemplary, reference Figure 2 ,as well as Figures 4 to 7 , the number of the first electrode terminal 23 and the positive electrode mounting hole can be one, the number of the fourth electrode terminal 42 and the negative electrode mounting hole can be two, and the two negative electrode mounting holes are located on both sides of one positive electrode mounting hole. Exemplarily, the positive electrode mounting hole can be located at the center of the tube body 10, so that the first electrode terminal 23 can be assembled at the center of the tube body 10. The two negative electrode mounting holes can be arranged on both sides of the positive electrode mounting hole, so that the two second electrode terminals 24 are arranged between the first electrode terminals 23. Therefore, when the microphone 40 is placed in the accommodating cavity 11 of the tube body 10, there is no need to pay attention to the direction of the microphone 40.

[0096] For example, the first terminal may use a pin connector such as but not limited to a Pogopin to simplify the arrangement of the electrode terminal. For example, the first electrode terminal 23 may be a pin connector, and the second electrode terminal 24 may be two pin connectors, which are respectively arranged on both sides of the first electrode terminal 23.

[0097] When setting the second terminal on the microphone 40, various methods can be used. For example, refer to Figure 5 , Figure 6 and Figure 7 , the second terminal is arranged at the bottom of the microphone 40, the second terminal at least includes a third electrode terminal 41 and a fourth electrode terminal 42, and the third electrode terminal 41 and the fourth electrode terminal 42 are insulated and separated. Exemplarily, the third electrode terminal 41 can be a contact located at the bottom of the microphone 40, and the third electrode terminal 41 can be located at the center of the bottom of the microphone 40. The fourth electrode terminal 42 can be a ring-shaped metal conductive sheet, and the third electrode terminal 41 is located inside the fourth electrode terminal 42 and is insulated and separated from the fourth electrode terminal 42 by an insulating ring. It should be explained that the bottom of the microphone 40 refers to: the end position of the microphone 40 opposite to the microphone head. When the microphone 40 is placed in the tube body 10, the bottom of the microphone 40 is opposite to the base 20, and the third electrode terminal 41 on the microphone 40 abuts on the first electrode terminal 23 of the base 20, and the fourth electrode terminal 42 on the microphone 40 abuts on the second electrode terminal 24 of the base 20. Exemplarily, the second terminal can be a conductive sheet or a conductive ring to simplify the arrangement of the electrode terminal.

The fourth electrode terminal 42 can be a conductive ring, and the third electrode terminal 41 is located inside the conductive ring and is insulated and separated by an insulating ring. The material of the conductive sheet or the conductive ring can be a structure such as but not limited to a copper sheet, an aluminum sheet, etc. Exemplarily, a battery is arranged inside the microphone 40, and the battery is connected to the second terminal, so that the charging device can charge the battery inside the microphone 40 through the second terminal.

Exemplarily, refer to Figure 4 and Figure 7 A first annular magnetic member 25 is disposed on the surface of the base 20 facing the tube body 11, and a second annular magnetic member 43 is disposed at the bottom of the microphone 40. When at least part of the microphone 40 is placed in the accommodating cavity 11, the first annular magnetic member 25 is attracted to the second annular magnetic member 43. The specific arrangement can be in a variety of ways.

[0099] Exemplary, reference Figure 4 , a first annular magnetic component 25 may be provided on the surface of the base 20 facing the tube body 10, wherein the electrode mounting hole 21 is located on the inner side of the first annular magnetic component 25, and the first annular magnetic component 25 is used to attract the microphone 40.

When the microphone 40 is placed in the tube body 10, the second annular magnetic component 43 at the bottom of the microphone 40 can be attracted together with the first annular magnetic component 25 on the base 20. In addition to the pressure of the second terminal abutting against the first terminal due to the gravity of the microphone 40 itself, the suction force generated by the two annular magnetic components is also increased, so that the second terminal can be reliably and stably abutted against the first terminal, thereby improving the reliability and stability of the electrical connection between the second terminal and the first terminal.

[0100] Exemplary, reference Figure 7 By having a built-in battery and a second annular magnetic part 43 in the microphone 40, when the microphone 40 is placed in the tube body 10 of the charging device, the first annular magnetic part 25 and the second annular magnetic part 43 can utilize magnetic attraction to strongly attach the microphone 40 to the first terminal of the base 20, and it is not easy to fall off.
