Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a battery positioning structure. Background Technology

[0002] Desktop microphones are miniature microphones specifically designed for close-range sound pickup. They typically feature a compact size and a design that allows for easy placement on a desktop. The basic functions of a desktop microphone include converting sound into electrical signals for amplification and processing by a computer or other devices. They are widely used in voice communication, game voice chat, live streaming, remote conferencing, and recording production, and are particularly suitable for personal users and small studios.

[0003] To improve the ease of use of microphones, desktop microphones have gradually evolved into wireless connections. However, wireless microphones face a technical challenge: optimizing battery space. In existing technologies, the battery of a wireless microphone is integrated into an internal support structure. This internal support structure is a vertical substrate, with the electronic control unit and battery distributed on both sides of the substrate. During assembly, the installer needs to first install the battery and electronic control unit together on the vertical substrate, and then install the vertical substrate into the bottom shell.

[0004] However, during the assembly process, the operator or assembly equipment needs to drive the substrate to move the battery integrated on the substrate. Due to the relatively large size and weight of the battery, it is easy to fall off during the movement, which will affect the progress of the microphone assembly process. The battery integrated on the substrate will always generate heat during operation. The heat radiates to the circuit control board on the substrate, which will affect the normal operation of the microphone's electronic control unit. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a battery positioning structure to solve the problems mentioned in the background section. To achieve the above objective, the present utility model adopts the following technical solution:

[0006] A battery positioning structure for mounting a microphone power supply and a microphone control unit electrically connected to the power supply;

[0007] The battery positioning structure includes:

[0008] case;

[0009] A circuit board bracket, at least a portion of which is assembled and connected to the housing;

[0010] The power supply is located on the housing; the microphone control unit is located on the circuit board bracket.

[0011] Optionally, the power supply is detachably connected to the housing.

[0012] Optionally, the housing is provided with a battery compartment, the battery compartment and the power supply are connected and adapted, and there is a certain gap between the battery compartment and the microphone control unit on the circuit board bracket.

[0013] Optionally, the battery compartment covers at least a portion of the power source, and the battery compartment is provided with a mounting slot capable of engaging and adapting to the end of the power source.

[0014] Optionally, the sidewall of the battery compartment is formed by the combination of the upright plate and the sidewall of the shell.

[0015] Optionally, the battery compartment and the electronic control unit are respectively disposed on both sides of the circuit board bracket.

[0016] Optionally, the housing is provided with a receiving cavity with an opening at one end, and the battery compartment is disposed in the receiving cavity, with the opening of the battery compartment facing the same direction as the receiving cavity.

[0017] Optionally, the housing is provided with a substrate positioning structure for mounting the circuit board bracket.

[0018] Optionally, the circuit board support includes at least two sets of reinforcing ribs, all of which are spaced apart to form at least one set of positioning grooves, and the bottom of the circuit board support can be snapped into the positioning grooves.

[0019] Optionally, the circuit board support is provided with a clearance slot for preventing the power supply from being exposed to air.

[0020] Compared with the prior art, the advantages of this utility model are that by setting a battery compartment on the inner side wall of the housing and assembling and connecting the circuit board bracket inside the housing, the microphone electronic control unit is installed on the circuit board bracket, which improves the convenience and stability of the circuit board bracket assembly process; and the battery compartments are located on both sides of the circuit board bracket, and the separate design of the microphone electronic control unit and the power supply maintains a certain distance, which greatly reduces the heat exchange between the power supply and the electronic control unit, thereby reducing the impact of the power supply heat on the operation of the electronic control unit and effectively improving the stability of the microphone.

[0021] By setting the power supply and housing to be detachably connected, the power supply can be replaced separately after its service life is exhausted without affecting other electronic control units, further improving the practicality of the battery positioning structure.

[0022] The power supply and battery compartment adopt an insert-type snap-fit ​​method, which can replace the traditional screw-fastening installation method. This can improve the installation speed of the power supply. At the same time, compared with the screw-fastening method, which requires additional screw components and suffers losses due to accidental breakage during screw fastening, the insert-type snap-fit ​​method does not require additional components as limiting units, and the disassembly and assembly method has a greater fault tolerance rate. This can further improve the production efficiency of the battery positioning structure and reduce the installation cost of the battery positioning structure.

[0023] By designing the battery compartment to cover one end of the power supply, operators can complete assembly without spending excessive time on snapping it in place. When it is necessary to remove the power supply, users can easily detach it from the mounting slot without spending excessive time pulling it out. The microphone does not generate significant mechanical vibration during use, and even with the end of the power supply covered, the mounting slot still provides sufficient locking and clamping effect. Furthermore, the low-depth battery compartment improves both the stability of the power supply and the efficiency of assembly.

[0024] The substrate positioning structure enables the edge of the circuit board bracket to fully abut against the side wall or inner wall of the receiving cavity after installation, preventing the circuit board bracket from wobbling and shaking, and effectively improving the installation stability of the circuit board bracket.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0035] like Figure 1-2 As shown, one embodiment of this utility model is: the battery positioning structure is used to install the power supply of the microphone and the microphone control unit 4 electrically connected to the power supply;

[0036] The battery positioning structure includes a housing 1 and a circuit board bracket 2. A power supply 3 is installed inside the housing 1. The lower part of the circuit board bracket 2 is assembled and connected inside the housing 1. A microphone control unit 4 is installed at the lower part of the circuit board bracket 2, and the microphone body is installed at the upper part of the circuit board bracket 2. This way, during assembly, the power supply 3 is assembled onto the housing 1, rather than onto the circuit board bracket 2, reducing the weight of the circuit board bracket 2 during assembly and improving its ease of use and stability. Furthermore, after installation, the microphone control unit 4 is mounted on the circuit board bracket 2, and the power supply 3 is mounted on the side wall of the housing 1, resulting in a split-type microphone design. The electronic control unit 4 and the power supply 3 are kept at a certain distance. Compared with the prior art, where the battery and circuit board are distributed on both sides of the circuit board mounting bracket and the battery and circuit board are abutted by the mounting bracket, the heat of the battery can be transferred to the circuit board by heat transfer, resulting in a high operating temperature of the circuit board and affecting the technical problem of use. The battery positioning structure provided in this utility model embodiment is always set in a non-direct abutment state after the power supply 3 and the circuit board bracket 2 are installed, which greatly reduces the heat exchange between the power supply 3 and the electronic control unit 4, thereby reducing the impact of the heat of the power supply 3 on the operation of the electronic control unit 4 and effectively improving the stability of the microphone.

[0037] In one embodiment, the power supply 3 is detachably connected to the housing 1, which facilitates the separate installation and removal of the power supply 3. Although traditional rechargeable power supplies can achieve charge and discharge cycles, there is a loss of energy storage as the usage time increases, i.e., lifespan. When the battery lifespan is exhausted, the battery cannot be used. The installation method of the power supply 3 with a detachable design allows the power supply 3 to be replaced separately after its lifespan is exhausted without affecting other electronic control units, further improving the practicality of the battery positioning structure.

[0038] In one embodiment, such as Figure 3 As shown, a battery compartment 5 is provided on the housing 1, and the battery compartment 5 and the power supply 3 are connected and adapted.

[0039] Specifically, the battery compartment 5 is located inside the housing 1, and the power supply 3 and the battery compartment 5 are snapped together. When assembling the power supply 3, simply inserting the power supply 3 into the battery compartment 5 will lock the power supply 3 in place. The snap-fit ​​method can replace the traditional screw-locking installation method, which is beneficial to improving the installation speed of the power supply 3. At the same time, compared with the screw-locking installation method, which requires additional screw components and suffers losses due to unexpected situations such as breakage during screw-locking, the snap-fit ​​method does not require additional components as limiting units, and the disassembly and assembly method has a large fault tolerance rate, which can further improve the production efficiency of the battery positioning structure and reduce the installation cost of the battery positioning structure.

[0040] In one embodiment, such as Figure 1As shown, the battery compartment 5 covers one end of the power supply 3.

[0041] Specifically, the battery compartment 5 is provided with a mounting groove for engaging the power supply 3. The depth of the mounting groove is less than the length of the power supply 3. When the power supply 3 is engaged in the mounting groove, the groove wall is tightly fitted to a portion of the side wall of the power supply 3. The end of the power supply 3 away from the mounting groove extends outside the groove, and the end of the power supply 3 extending outside the groove is electrically connected to the microphone control unit 4 via a ribbon cable. In this embodiment, after the power supply 3 is installed, only its end is engaged and covered by the inner wall of the mounting groove. The advantage of this design is that during assembly, the operator does not need to spend too much time engaging the groove to complete the assembly; when it is necessary to disassemble the power supply 3, the user does not need to spend too much time pulling it out to easily remove the power supply 3 from the mounting groove; the microphone does not generate significant mechanical vibration during use, and even when the end of the power supply 3 is covered, the mounting groove can still achieve sufficient limiting engagement effect. Therefore, using a low-depth battery compartment 5 improves the stability of the power supply 3 while also improving assembly efficiency.

[0042] In one embodiment, such as Figure 3 As shown, the sidewall of the battery compartment 5 is formed by the combination of the upright plate and the sidewall of the housing 1.

[0043] Specifically, the two ends of the upright plate are connected to the side wall of the housing 1 respectively. The upright plate is bent and deformed away from the inner wall of the housing, so that the cross-sectional shape of the upright plate is curved. The side wall of the housing 1 is part of the battery compartment 5. One end of the battery compartment 5 is open, and the other end is the bottom of the housing 1. This design can save internal space of the housing 1 and optimize the internal space of the housing.

[0044] In one embodiment, the height of the upright plate is less than the length of the power supply 3. The upright plate, together with the inner wall of the housing 1 and the bottom wall of the housing 1, forms the battery compartment 5. In this embodiment, the mounting groove is the inner cavity of the battery compartment 5. The mounting groove is fitted to the shape of the power supply. When the end of the power supply is inserted into the mounting groove, the inner wall of the housing and the upright plate are both in interference fit with the power supply.

[0045] In one embodiment, such as Figure 5As shown, the bottom of the upright plate is fixedly connected to the bottom wall of the housing 1 via a connecting seat 10. The mounting groove is formed on the connecting seat 10. The upright plate extends around the opening of the mounting groove and along the direction of the power supply 3. A receiving groove is formed between the upright plate and the inner wall of the housing 1. The diameter of the receiving groove is slightly larger than the outer diameter of the power supply 3. One end of the power supply 3 is engaged in the mounting groove, and the other end of the power supply extends into the receiving groove. The height of the upright plate is greater than the length of the power supply 3, so that the upright plate can cooperate with the connecting seat to cover the entire power supply 3. During installation, the operator first places the power supply 3 into the receiving groove. Since the outer diameter of the power supply is small... The power supply can smoothly enter the receiving groove due to its inner diameter, until its end abuts against the mounting groove. The operator continues to press the power supply to lock the end into the mounting groove, thus completing the installation. After installation, one end of the power supply is interference-fitted with the mounting groove, and the other end of the power supply is located in the receiving groove. There is a gap between the corresponding side wall of the power supply and the groove wall of the receiving groove. This design improves the ease of installation of the power supply. At the same time, the overall height of the split-type upright plate and connecting seat is greater than that of the power supply, thus covering the entire power supply. The upright plate and connecting seat reduce the heat radiation impact of the power supply on the electronic control unit, improving the stability of the electronic control unit.

[0046] In one embodiment, such as Figure 1 As shown, the battery compartment 5 and the electronic control unit are respectively located on both sides of the circuit board bracket 2.

[0047] Specifically, the battery compartment 5 is located on the housing 1 on the left side of the circuit board support 2, and the electronic control unit is located on the right side of the circuit board support 2. In this embodiment, the electronic control unit consists of electrical components such as indicator lights, capacitors, and resistors mounted on the PCB board. The PCB board is mounted on the circuit board support, and the electronic control unit is plugged into or soldered onto the circuit board. The end of the electronic control unit extends away from the PCB board and into the inner cavity of the housing. Since the electronic control unit and the battery compartment are distributed on both sides of the circuit board, the extended end of the electronic control unit will not be close to the power source, thereby improving the space utilization of the housing, reducing the degree to which the electronic control unit is affected by the power source temperature, and achieving space optimization.

[0048] In one embodiment, the battery compartment 5 and the housing 1 are integrally formed.

[0049] Specifically, the battery compartment 5 and the shell 1 are integrally fixedly connected, which facilitates the production of the shell 1 and improves the structural strength of the battery compartment 5. It can be understood that the integral molding method includes, but is not limited to: integral molding of plastic material by injection molding / integral molding of metal material by casting / integral molding of plastic material by 3D printing technology, etc., all of which are integral molding methods.

[0050] In one embodiment, such as Figure 2-3 As shown, a receiving cavity 7 with one end open is provided inside the housing 1, and the battery compartment 5 is disposed inside the receiving cavity 7.

[0051] In this embodiment, the housing 1 has a receiving cavity 7 with an opening at the top, and the battery compartment 5 is disposed in the receiving cavity 7. The opening of the battery compartment faces the same direction as the receiving cavity. The top opening of the battery compartment 5 facilitates the insertion of the power supply 3 from the opening position of the receiving cavity 7.

[0052] In one embodiment, such as Figure 3 As shown, the housing 1 is provided with a substrate positioning structure 6 for mounting the circuit board bracket 2. The substrate positioning structure 6 facilitates the assembly and positioning of the circuit board bracket 2 and the housing 1.

[0053] In one embodiment, such as Figure 4 As shown, the substrate positioning structure 6 includes at least two sets of reinforcing ribs, all of which are spaced apart to form at least one set of positioning grooves 61, and the bottom of the circuit board bracket can be snapped into the positioning grooves 61.

[0054] In one embodiment, the housing is configured in a barrel shape, and there are two positioning grooves 61. The two positioning grooves 61 are symmetrically distributed around the center of the bottom wall of the receiving cavity, and both positioning grooves 61 are formed at the corner where the side wall and the bottom wall of the receiving cavity meet. In this embodiment, the end of the circuit board bracket for mounting the electronic control components is configured in a rectangular plate shape, and the bottom of the circuit board bracket is formed with two sharp edges. During installation, the operator aligns the two sharp edges with the corresponding positioning grooves 61, and then presses and snaps the circuit board bracket into the positioning grooves 61 to complete the installation of the circuit board bracket, effectively improving the ease of installation of the circuit board bracket. At the same time, the positioning grooves 61 located at the corner of the receiving cavity allow the edges of the circuit board bracket to fully abut against the side wall or inner wall of the receiving cavity 7 after installation, preventing the circuit board bracket from swaying and shaking, and effectively improving the installation stability of the circuit board bracket.

[0055] In other embodiments, the number of positioning grooves 61 is one, and the positioning groove 61 is located at the center of the bottom wall of the receiving cavity 7. Using one positioning groove 61 helps to reduce the manufacturing cost of the reinforcing rib and reduce the overall structural complexity of the microphone.

[0056] In one embodiment, the reinforcing rib is arranged in a square plate-like structure, and the end of the circuit board bracket is arranged in a rectangular plate-like structure. The positioning groove 61 is formed by two sets of reinforcing ribs spaced apart on the inner wall of the receiving cavity. The two sets of reinforcing ribs are arranged parallel to each other. When the circuit board bracket is installed in the positioning groove, both sets of reinforcing ribs are tightly fitted to the side wall of the circuit board bracket. In other embodiments, the reinforcing rib may be arranged in an arc-shaped plate-like structure or an annular plate-like structure. All the reinforcing ribs are integrally molded with the housing by injection molding.

[0057] In one embodiment, such as Figure 4 As shown, the length direction of the positioning groove 61 is consistent with the height direction of the receiving cavity 7.

[0058] Specifically, the opening of the receiving cavity 7 and the opening of the positioning groove 61 face the same direction and are set along the height direction of the receiving cavity 7, so that the substrate can be inserted into the positioning groove 61 from the opening end of the receiving cavity 7.

[0059] In one embodiment, the circuit board bracket 2 is provided with a clearance groove for preventing the power supply 3 from being exposed to air, so as to avoid mutual interference between the circuit board bracket 2 and the power supply 3 when the circuit board bracket 2 is installed.

[0060] This invention improves the ease of assembly and stability of the circuit board bracket by setting a battery compartment on the inner wall of the housing and assembling and connecting the circuit board bracket inside the housing. The microphone control unit is mounted on the circuit board bracket. The battery compartments are located on both sides of the circuit board bracket. The separate design of the microphone control unit and the power supply maintains a certain distance, which greatly reduces the heat exchange between the power supply and the control unit, thereby reducing the impact of the power supply heat on the operation of the control unit and effectively improving the stability of the microphone.

[0061] By setting the power supply and housing to be detachably connected, the power supply can be replaced separately after its service life is exhausted without affecting other electronic control units, further improving the practicality of the battery positioning structure.

[0062] The power supply and battery compartment adopt an insert-type snap-fit ​​method, which can replace the traditional screw-fastening installation method. This can improve the installation speed of the power supply. At the same time, compared with the screw-fastening method, which requires additional screw components and suffers losses due to accidental breakage during screw fastening, the insert-type snap-fit ​​method does not require additional components as limiting units, and the disassembly and assembly method has a greater fault tolerance rate. This can further improve the production efficiency of the battery positioning structure and reduce the installation cost of the battery positioning structure.

[0063] By designing the battery compartment to cover one end of the power supply, operators can complete assembly without spending excessive time on snapping it in place. When it is necessary to remove the power supply, users can easily detach it from the mounting slot without spending excessive time pulling it out. The microphone does not generate significant mechanical vibration during use, and even with the end of the power supply covered, the mounting slot still provides sufficient locking and clamping effect. Furthermore, the low-depth battery compartment improves both the stability of the power supply and the efficiency of assembly.

[0064] The substrate positioning structure enables the edge of the circuit board bracket to fully abut against the side wall or inner wall of the receiving cavity after installation, preventing the circuit board bracket from wobbling and shaking, and effectively improving the installation stability of the circuit board bracket.

[0065] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
