Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, and more specifically, it relates to a wireless microphone with a layered battery compartment. Background Technology

[0002] Wireless microphones are audio devices used in scenarios such as speeches, live broadcasts, stage performances, and interviews to collect sound signals and transmit them wirelessly to receiving devices. To avoid interruption of use due to the depletion of a single battery and to meet the need for continuous audio recording over long periods, they are often equipped with multiple spare batteries. This allows for quick replacement when the main battery runs out of power, ensuring the continuity of sound collection and transmission. However, traditional wireless microphones often use a single battery compartment design, which can only hold one main battery to power the device. When the main battery runs out of power, the user needs to pause the current usage scenario and then search for the spare battery from a separately carried storage box. This is not only cumbersome and time-consuming, but also poses the problem of the spare battery being easily missed or lost due to separate storage. It completely fails to achieve integrated storage of the main and spare batteries, which increases the user's carrying burden and makes it difficult to cope with usage scenarios that require high continuity of equipment. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a layered battery compartment for a wireless microphone. This solves the technical problems of existing wireless microphones, where a single battery compartment can only hold one main battery. When the battery is depleted, the microphone needs to be paused to find a separately stored spare battery, which is cumbersome, prone to loss, and cannot be integrated for storage, making it difficult to adapt to high continuity requirements.

[0004] The purpose and function of the wireless microphone in the layered battery compartment of this utility model are achieved by the following specific technical means:

[0005] A layered battery compartment wireless microphone includes a microphone body for collecting sound signals and transmitting them wirelessly, and a battery compartment for powering the microphone body. The battery compartment is installed at the bottom of the microphone body and includes a first compartment for accommodating a main power battery and a second compartment for accommodating a spare battery and providing charging functionality. The microphone body, the first compartment, and the second compartment are arranged longitudinally in sequence. One end of the first compartment is connected to the microphone body via a first connecting part, and the other end is connected to the second compartment via a second connecting part. A locking component is provided inside the first compartment, and the battery is secured inside the first compartment by the locking component. A charging base is provided inside the second compartment, and two sets of batteries are secured on the charging base.

[0006] According to a preferred embodiment, a connecting sleeve is provided on the top of the first grading compartment, and a connecting groove is provided on the microphone body corresponding to the connecting sleeve, with the connecting sleeve passing through the connecting groove; the first connecting part includes limiting blocks symmetrically arranged on both sides of the connecting sleeve and two sets of rotating grooves symmetrically opened on the inner wall of the connecting groove, with a limiting slot and a limiting through slot respectively opened at both ends of the rotating groove, and the limiting through slot penetrating downward through the microphone body.

[0007] According to a preferred embodiment, the center line between the two sets of limiting slots is perpendicular to the center line between the two sets of limiting through slots.

[0008] According to a preferred embodiment, the first connecting portion further includes four sets of first magnetic blocks, wherein two sets of first magnetic blocks are located at the top of the connecting groove, and the other two sets of first magnetic blocks are located at the bottom of the connecting sleeve. The four sets of first magnetic blocks correspond to each other, and the corresponding surfaces are arranged with the same pole. The limiting block is engaged in the limiting groove, and through the repulsive force generated between the four sets of first magnetic blocks, the limiting block forms a downward pushing force. A gap is formed between the first grading compartment and the microphone body. An elastic element is provided at the top of the first grading compartment, and the elastic element is located in the gap and abuts against the bottom of the microphone body.

[0009] According to a preferred embodiment, the locking assembly includes two sets of locking members. The first grading compartment has a battery slot and two sets of locking slots. The two sets of locking slots are located on both sides of the battery slot, and the locking members pass through the locking slots. One end of the locking member is set as a locking end, and the other end is set as a pulling end. The locking end extends out of the locking slot and is located in the battery slot, and the battery is locked between the battery slot and the locking end.

[0010] According to a preferred embodiment, the locking assembly further includes multiple sets of springs. The first grading compartment also has two sets of movable grooves, each located at one end of a locking groove. Multiple sets of first positioning posts are provided on the pulling end. A second positioning post is provided on one side of each movable groove corresponding to the first positioning post. The multiple sets of springs are located within the two sets of movable grooves and are sleeved between the first and second positioning posts. A pulling groove is provided on the first grading compartment, with both ends communicating with the two sets of movable grooves. A pulling rope is provided within the pulling groove, with both ends connected to the pulling ends of the two sets of locking components. A pulling ring is provided in the middle of the pulling rope.

[0011] According to a preferred embodiment, the second grading compartment includes a first outer shell and a second outer shell, which are connected to each other on one side. Multiple sets of second magnetic blocks are provided on the top of both the first and second outer shells. The second grading compartment is magnetically connected to the first grading compartment via the second magnetic blocks. The charging base is located between the first and second outer shells and is rotatably connected to both. The charging base has two sets of charging slots, and the battery is secured in the charging slots. The first outer shell has a retrieval slot, and a charging part is provided on one side of the second outer shell. The charging base is electrically connected to the charging part.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By vertically integrating a first and second compartment at the bottom of the microphone body, the first compartment houses the main power battery and is securely fixed with a locking mechanism, preventing power instability caused by battery movement. The charging dock in the second compartment can simultaneously store two sets of spare batteries, eliminating the need for a separate storage box and completely solving the problem of spare batteries being easily lost or misplaced, significantly reducing the user's carrying burden. When the main battery is depleted, the user does not need to pause the use to search for a spare battery; they can directly remove the charged spare battery from the second compartment for replacement. Combined with the convenient operation of the locking mechanism in the first compartment (pulling the ring unlocks the locking mechanism), battery replacement time is significantly shortened, ensuring smooth operation in scenarios with high equipment continuity requirements, such as presentations and live broadcasts.

[0014] 2. The first tiered compartment is connected to the microphone body via a connecting sleeve and a connecting slot. Combined with the limiting block, the rotating slot, and the repulsive force of four sets of identical first magnetic blocks and the support of elastic elements, it achieves a secure connection between the first tiered compartment and the microphone body, while also allowing for quick disassembly via rotation for easy maintenance. The second tiered compartment is magnetically connected to the first tiered compartment via a second magnetic block, and the charging base is rotatable. Combined with the access slot in the first outer shell, it facilitates the placement and removal of the spare battery and the monitoring of its charging status. Meanwhile, the locking assembly, with its spring, first positioning post, and second positioning post, automatically resets the locking mechanism, ensuring stable engagement of the main battery. The overall structural design balances stability and convenience, meeting the operational needs of different usage scenarios. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 5 As shown, this utility model provides a layered battery compartment wireless microphone, including a microphone body 11 for collecting sound signals and transmitting them wirelessly, and a battery compartment for powering the microphone body 11. The microphone body 11, as the core functional component, is responsible for capturing sound signals in scenarios such as speeches, live broadcasts, and interviews, and converting the signals into wireless signals for transmission to the receiving device, thus meeting the user's sound reception needs while on the move. The battery compartment, as the power supply core, is directly installed at the bottom of the microphone body 11, forming a vertically integrated structure with the microphone body 11, avoiding the burden of carrying an additional independent battery compartment.

[0025] The battery compartment is specifically divided into a first-level compartment 21 and a second-level compartment. The core function of the first-level compartment 21 is to house the main power supply battery, providing fixed space for the main power supply battery while ensuring that the main power supply battery can stably supply power to the microphone body 11, ensuring the basic operation of the device. The second-level compartment has a dual function: on the one hand, it is used to house two sets of backup batteries, solving the problem of insufficient battery life in traditional single battery compartments; on the other hand, it has a charging function, which can replenish the power of the backup batteries when they are idle, ensuring that the backup batteries are always in a usable state.

[0026] From the overall layout, the microphone body 11, the first compartment 21, and the second compartment are arranged vertically in sequence. This vertical structure can minimize the lateral space occupation, making the device smaller and more portable, suitable for handheld use or fixed to clothing.

[0027] One end of the first tiered compartment 21 is connected to the microphone body 11 via a first connecting part, achieving a stable assembly and power conduction between the two. The other end is connected to the second tiered compartment via a second connecting part, ensuring that the storage areas of the backup battery and the main power supply battery are independent yet closely related. At the same time, a locking component is provided inside the first tiered compartment 21, which secures the main power supply battery inside the first tiered compartment 21, preventing poor contact caused by shaking during device movement and affecting power supply stability. The second tiered compartment is provided with a charging base 31, on which the two sets of backup batteries are respectively secured, achieving orderly storage of the backup batteries and ensuring a stable electrical connection between the backup batteries and the charging base 31, guaranteeing a smooth charging process.

[0028] like Figure 2 , Figure 3 , Figure 5 As shown, a connecting sleeve 22 is provided on the top of the first grading compartment 21. The connecting sleeve 22 is a hollow columnar structure, and its outer diameter matches the inner diameter of the connecting groove 12 opened on the microphone body 11. When the first grading compartment 21 needs to be assembled with the microphone body 11, the connecting sleeve 22 can be directly inserted into the connecting groove 12 to achieve the initial positioning of the two through physical nesting, providing a basis for subsequent fixation.

[0029] The first connecting part, as the core connecting structure between the first grade compartment 21 and the microphone body 11, includes two key components: one part is the limiting blocks 23 symmetrically arranged on both sides of the connecting sleeve 22. The limiting blocks 23 are protruding structures that extend outward from the outside of the connecting sleeve 22, and their length and thickness are adapted to the space of the inner wall of the connecting groove 12; the other part is two sets of rotating grooves 13 symmetrically opened on the inner wall of the connecting groove 12. The rotating grooves 13 are arc-shaped grooves, and their curvature matches the rotation trajectory of the limiting blocks 23. When the connecting sleeve 22 is inserted into the connecting groove 12, the limiting blocks 23 can enter the rotating grooves 13 as the connecting sleeve 22 rotates and move along the path of the rotating grooves 13.

[0030] Limiting slots 14 and limiting through slots 15 are respectively provided at both ends of the rotating groove 13. The limiting slot 14 is a recessed structure. When the limiting block 23 moves to the end of the rotating groove 13, it can be inserted into the limiting slot 14. The side wall of the limiting slot 14 restricts the lateral movement of the limiting block 23, thereby achieving the initial fixation of the first grading compartment 21 and the microphone body 11. The limiting through slot 15 is a through slot that extends downward through the microphone body 11. Its function is to provide an entry and exit channel for the limiting block 23. When it is necessary to disassemble the first grading compartment 21, the limiting block 23 can move along the rotating groove 13 to the limiting through slot 15, and then detach from the limiting through slot 15 as the connecting sleeve 22 is pulled out, thus completing the separation of the first grading compartment 21 and the microphone body 11, which facilitates the subsequent replacement or maintenance of the main power supply battery inside the first grading compartment 21.

[0031] The centerline between the two sets of limiting slots 14 is perpendicular to the centerline between the two sets of limiting through slots 15. This perpendicular distribution structure has a clear functional significance. From an assembly perspective, after the limiting block 23 enters the rotating slot 13 from the limiting through slot 15, it needs to rotate 90 degrees along the rotating slot 13 to engage with the limiting slot 14. This rotation process allows the connecting sleeve 22 and the connecting slot 12 to nest more tightly, preventing the first grading chamber 21 from rotating unexpectedly during use. From a fixing perspective, the perpendicularly distributed centerline allows the two sets of limiting blocks 23 to limit the first grading chamber 21 from two vertical directions after engaging with the limiting slot 14, dispersing the pressure from the weight of the first grading chamber 21 itself and the main power supply battery, reducing the connection loosening caused by excessive force in one direction, further improving the stability of the connection between the first grading chamber 21 and the microphone body 11, ensuring that the power conduction between the two is always smooth and that there will be no power interruption due to connection problems.

[0032] The first connecting part also includes four sets of first magnetic blocks 24. These four sets of first magnetic blocks 24 are symmetrically distributed. Two sets of first magnetic blocks 24 are fixed to the top of the connecting groove 12 and embedded in the preset groove of the inner wall of the connecting groove 12, keeping them flush with the connecting groove 12 and not affecting the insertion of the connecting sleeve 22. The other two sets of first magnetic blocks 24 are fixed to the bottom of the connecting sleeve 22 and are also embedded in the preset groove of the connecting sleeve 22, ensuring that when the connecting sleeve 22 is inserted into the connecting groove 12, the four sets of first magnetic blocks 24 can correspond to each other, that is, the first magnetic blocks 24 at the top of the connecting groove 12 and the first magnetic blocks 24 at the bottom of the connecting sleeve 22 are directly opposite each other.

[0033] The corresponding surfaces of the four sets of first magnetic blocks 24 are set with the same pole. According to the physical principle that like poles repel each other, when the connecting sleeve 22 is inserted into the connecting groove 12 and the limiting block 23 is locked in the limiting groove 14, the four sets of first magnetic blocks 24 will generate a repulsive force. This repulsive force will exert a downward pushing force on the limiting block 23, firmly pressing the limiting block 23 into the limiting groove 14, preventing the limiting block 23 from coming out of the limiting groove 14 during the movement or vibration of the device, and further strengthening the fixing effect between the first grading compartment 21 and the microphone body 11.

[0034] Meanwhile, due to the repulsive force, a gap will naturally form between the first grading compartment 21 and the microphone body 11. This gap can prevent wear caused by direct contact between the two and also provide space for the subsequent installation of the elastic element 25. At the top of the first grading compartment 21, corresponding to the gap, an elastic element 25 is provided. One end of the elastic element 25 is fixed to the top of the first grading compartment 21, and the other end abuts against the bottom of the microphone body 11. In its natural state, the elastic element 25 is in a slightly compressed state, and its own elasticity forms an upward supporting force on the microphone body 11, which balances the downward pushing force generated by the first magnetic block 24. This allows the first grading compartment 21 and the microphone body 11 to maintain a relatively stable positional relationship when connected, reducing collision noise caused by vibration. At the same time, when the device is subjected to slight impact, the deformation of the elastic element 25 can absorb the impact force, protect the structural integrity of the first connection part, and extend the service life of the device.

[0035] like Figure 2 , Figure 4 As shown, the locking assembly includes two sets of locking members 41, which are symmetrically distributed inside the first grading compartment 21 to jointly secure the main power supply battery. Inside the first grading compartment 21, a battery slot 26 and two sets of locking slots 42 are specifically provided. The battery slot 26 is a recessed cavity structure, its size matching the shape of the main power supply battery, providing dedicated placement space for the main power supply battery and ensuring it remains stably centered within the first grading compartment 21, preventing any positional shift from affecting the power connection with the microphone body 11. The two sets of locking slots 42 are located on either side of the battery slot 26 and are interconnected. The width of the locking slots 42 matches the width of the locking members 41, allowing the locking members 41 to smoothly pass through and move along the extension direction of the locking slots 42.

[0036] The locking member 41 has different functions at both ends. One end is set as the locking end and the other end is set as the pulling end. The end of the locking end is arc-shaped. In its natural state, the locking end will extend out of the locking groove 42 and into the battery compartment 26. When the main power supply battery is put into the battery compartment 26, the locking end will fit against the side wall of the main power supply battery. Together with the inner wall of the battery compartment 26, the main power supply battery is locked between the battery compartment 26 and the locking end, which restricts the movement of the main power supply battery in the up and down and left and right directions, and prevents the main power supply battery from shaking due to vibration during the carrying or use of the device, thus avoiding power transmission interruption.

[0037] The locking assembly also includes multiple sets of springs, which provide power support for the reset of the locking member 41. Within the first tiered compartment 21, two sets of movable slots 27 are provided. These slots are located at the ends of the two locking slots 42 furthest from the battery compartment 26 and are connected to the locking slots 42. The space of the movable slots 27 is larger than that of the locking slots 42, providing sufficient space for the installation of the springs and the movement of the pulling end of the locking member 41. On the pulling end of the locking member 41, multiple sets of first positioning posts 43 are provided. Each first positioning post 43 is a cylindrical protrusion. Correspondingly, on the side of the movable slot 27 near the locking slot 42, a second positioning post 44 is provided at the position corresponding to the first positioning post 43. The second positioning post 44 is also a cylindrical protrusion and coincides with the axis of the first positioning post 43. Multiple sets of springs are placed in two sets of movable slots 27, with one end of the spring sleeved on the first positioning post 43 and the other end sleeved on the second positioning post 44. The first positioning post 43 and the second positioning post 44 work together to prevent the spring from shifting or falling off during the extension and retraction process.

[0038] When the main power supply battery needs to be removed, the pulling end can be pulled by external force to move the locking part 41 away from the battery slot 26. At this time, the spring will be compressed and store elastic potential energy. When the external force is removed, the spring will release the elastic potential energy and push the locking part 41 to move closer to the battery slot 26, so that the locking end will automatically return to the battery slot 26, making it convenient to install the main power supply battery next time. In addition, a pull groove 45 is provided on the outer wall of the first compartment 21. The pull groove 45 is a long strip-shaped through groove, and its two ends are respectively connected to two sets of movable grooves 27. A pull rope 46 is provided in the pull groove 45. The pull rope 46 is made of flexible and wear-resistant material and can move along the pull groove 45. The two ends of the pull rope 46 are respectively fixedly connected to the pull ends of two sets of locking members 41. A pull ring 47 is provided in the middle of the pull rope 46. The pull ring 47 protrudes outside the pull groove 45. The user only needs to pull the pull ring 47 with his / her finger to move the pull ends of the two sets of locking members 41 simultaneously by pulling the rope 46, so as to realize the synchronous unlocking of the two sets of locking members 41 without having to operate the two sets of locking members 41 separately, simplifying the steps of removing the main power supply battery and improving the convenience of operation.

[0039] like Figure 2As shown, the second grading compartment includes a first outer shell 32 and a second outer shell 33. Both the first outer shell 32 and the second outer shell 33 are semi-shell structures, connected to each other on one side for easy maintenance of the internal charging base 31. Multiple sets of second magnetic blocks 34 are provided on the top of both the first outer shell 32 and the second outer shell 33. The second magnetic blocks 34 are sheet-like structures, and the polarities of the second magnetic blocks 34 on the first outer shell 32 and the second outer shell 33 are opposite. Correspondingly, a magnetic structure matching the polarity of the second magnetic blocks 34 is also provided at the bottom of the first grading compartment 21. When it is necessary to connect the second grading compartment to the first grading compartment 21, simply bring the second magnetic blocks 34 on the top of the second grading compartment close to the bottom of the first grading compartment 21, and the magnetic attraction force will achieve a quick connection without the need for tools. The connection is also easy to separate, improving the convenience of loading and unloading the second grading compartment.

[0040] The charging base 31 is located between the first outer shell 32 and the second outer shell 33, and the two sides of the charging base 31 are rotatably connected to the first outer shell 32 and the second outer shell 33 through pivots. Users can adjust the angle of the charging base 31 by rotating it to facilitate the insertion or removal of the spare battery. At the same time, a spring structure is provided between the charging base 31 and the second compartment. Specifically, a set of torsion springs is respectively fitted on the outer side of the pivots on both sides of the charging base 31. One end of the torsion spring is fixed to the side wall of the charging base 31, and the other end is fixed to the inner wall of the first outer shell 32 and the second outer shell 33. When a user needs to place or remove a spare battery, they simply push the charging base 31 to one side, causing it to rotate around the pivot. This causes the torsion spring to twist and store elastic potential energy. Once the charging base 31 has rotated to the appropriate angle, the user can easily install or remove the spare battery. When the user releases the charging base 31, the torsion spring releases its elastic potential energy, causing the charging base 31 to automatically rotate and reset, returning to its initial position that matches the internal space of the second compartment. This prevents the charging base 31 from shifting position after rotation, which could cause the first outer shell 32 and the second outer shell 33 to become stuck or unable to close completely.

[0041] Two sets of charging slots 35 are provided on the charging base 31. The size of the charging slots 35 is adapted to the backup battery, and the slots are provided with metal conductive contacts. When the backup battery is inserted into the charging slot 35, the electrodes of the backup battery will contact the conductive contacts in the charging slot 35 to form an electrical connection.

[0042] On the side wall of the first housing 32, a retrieval slot 36 is provided. The position of the retrieval slot 36 corresponds to the charging slot 35, and the width of the slot is greater than the thickness of the spare battery. When it is necessary to remove the spare battery, the user can easily pry the spare battery out of the charging slot 35 by inserting their finger through the retrieval slot 36, avoiding the problem of the spare battery being difficult to remove due to the charging slot 35 clamping the spare battery. A charging unit is provided on one side of the second housing 33. The charging unit has common interfaces such as Type-C, which can be connected to an external power source via a data cable. The internal circuit of the charging unit is electrically connected to the charging base 31 through wires. When an external power source is connected to the charging unit, the power will be transmitted to the charging base 31 through the circuit, and then to the spare battery through the conductive contacts in the charging slot 35, thereby charging the spare battery and ensuring that the spare battery is always fully charged and can be used to replace the main power supply battery at any time.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
