Description

Technical Field

[0001] The utility model relates to the technical field of sound amplification equipment, in particular to a microphone core installation structure and a handheld microphone with the microphone core installation structure. Background Art

[0002] In the contemporary audio equipment manufacturing industry, especially in the design and production field of handheld microphones, the microphone core is the core induction component of the microphone, and the stable installation of the microphone core is one of the key factors determining the performance and durability of the equipment. The traditional microphone core fixing technologies mainly include the adhesive fixing method and the mechanical fastening method, and both of these methods have limitations.

[0003] Among them, for the adhesive fixing method, that is, using a specific glue to paste the microphone core mounting seat to the bracket, this method is simple and easy to operate, and the cost is relatively low. However, it also brings a series of problems: First of all, the glue components often contain volatile organic compounds (VOCs), which pose a potential threat to the environment and human health in the long term; Secondly, the adhesive process requires time to cure, which prolongs the production cycle, and there may be a risk of reduced bonding strength in extreme environments; Finally, once it is necessary to repair or replace the microphone core, the disassembly of the adhesive fixing is extremely inconvenient, and it may cause damage to the bracket or the microphone core.

[0004] In addition, for the mechanical fastening method, usually using fasteners such as screws to achieve fixation, this method ensures relatively high fixing strength and stability. However, its disadvantages are also obvious: Special tools must be used during installation and disassembly, which increases the operation complexity and time cost; At the same time, frequent tightening and loosening may cause thread wear, affecting the service life, and in some compact designs, reserving enough space for screws will increase the volume and weight of the equipment.

[0005] In view of the above problems, the industry urgently needs a new type of microphone core installation technology, which can not only ensure the stability and reliability of the installation, but also simplify the assembly process, reduce the burden on the environment, and facilitate later maintenance and upgrading.

[0036] In the description of the present utility model, the description referring to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0037] In the contemporary audio equipment manufacturing industry, especially in the field of the design and production of handheld microphones, the microphone element is the core sensing component of the microphone, and the stable installation of the microphone element is one of the key factors determining the performance and durability of the device. The traditional microphone element fixing technologies mainly include the adhesive fixing method and the mechanical fastening method, and both of these methods have limitations.

[0038] Among them, the adhesive fixation method, that is, using a specific glue to paste the microphone core mounting seat onto the bracket, is simple and easy to implement, and the cost is relatively low. However, it also brings a series of problems: First of all, the glue components often contain volatile organic compounds (VOCs), which pose a potential threat to the environment and human health in the long term; Secondly, the adhesive process requires time to cure, extending the production cycle, and there may be a risk of reduced bonding strength in extreme environments; Finally, once it is necessary to repair or replace the microphone core, the disassembly of the adhesive fixation is extremely inconvenient and may cause damage to the bracket or the microphone core.

[0039] In addition, the mechanical fastening method usually uses fasteners such as screws to achieve fixation. This method ensures high fixation strength and stability. However, its disadvantages are also obvious: Special tools must be used during installation and disassembly, increasing the operation complexity and time cost; At the same time, frequent tightening and loosening may cause thread wear, affecting the service life, and in some compact designs, reserving enough screw space will increase the volume and weight of the device.

[0040] In view of the above problems, the industry urgently needs a new type of microphone core installation technology that can ensure the stability and reliability of installation, simplify the assembly process, reduce the burden on the environment, and facilitate later maintenance and upgrading.

[0041] For this reason, as Figures 1 to 3 shown, the microphone core installation structure proposed by the present utility model includes a bracket 100 and an installation component installed on the top of the bracket 100. Among them, the installation component includes a first installation ring 210, a second installation ring 220, and a microphone core mounting seat 300. The first installation ring 210 and the second installation ring 220 are arranged oppositely, and the microphone core mounting seat 300 is located between the first installation ring 210 and the second installation ring 220. The first installation ring 210 and the second installation ring 220 are assembled and fixed oppositely to fix the microphone core mounting seat 300. Optionally, the first installation ring 210 and the second installation ring 220 press and fix the microphone core mounting seat 300. By adopting a split-ring snap-fit installation design, the quick, glue-free, and tool-free installation of the microphone core mounting seat 300 is realized, significantly improving the production efficiency and reducing the adverse impact on the environment. It is easy to understand that the microphone core mounting seat 300 is used to install the microphone core component 400. For example, the microphone core component 400 is snap-fitted and installed with the microphone core mounting seat 300. In some applications, the microphone core component 400 and the microphone core mounting seat 300 are sold as a whole accessory. Therefore, the installation of the microphone core component 400 is completed once the microphone core mounting seat 300 is installed.

[0042] Referring again to Figure 1 and Figure 3, the first mounting ring 210 and the second mounting ring 220 are both semi-ring-shaped, so that the first mounting ring 210 and the second mounting ring 220 can fit the contour of the microphone core mounting seat 300 more closely, thereby improving the assembly accuracy and stability. At the same time, the semi-ring design reduces the weight of a single component, facilitates the operator's hand holding and alignment, further simplifies the installation process, and improves the overall assembly efficiency. Specifically, a plug-in block is provided on the side of the first mounting ring 210 facing the second mounting ring 220, and the second mounting ring 220 is provided with a plug-in slot corresponding to the plug-in block. The plug-in block is plugged and fixed to the plug-in slot to achieve fast and firm docking. Such a plug-in structure not only ensures the convenience of installation, but also enhances the connection stability between the first mounting ring 210 and the second mounting ring 220. It is not easy to loosen even when subjected to external force, thereby improving the overall reliability of the microphone core mounting structure. The plug-in block includes a first plug-in block 211 and a second plug-in block 212, and the plug-in slot includes a first plug-in slot 2201 and a second plug-in slot 2202. Optionally, the first plug-in block and the second plug-in block have the same shape (not shown in the figure). In some embodiments of the utility model, the first plug-in block 211 and the second plug-in block 212 have different shapes, the first plug-in block 211 is cylindrical, and the second plug-in block 212 is square columnar. Furthermore, the outer diameter of the end of the plug-in block is smaller than the outer diameter of the tail of the plug-in part, providing a natural guiding function, so that during the assembly process, the plug-in block can slide into the corresponding plug-in slot more easily and accurately, avoiding misalignment or jamming, improving the smoothness and efficiency of assembly, and also protecting the plug-in part from unnecessary damage.

[0043] Refer to Figure 2 and Figure 3 The first mounting ring 210 is provided with a first mounting half cavity 2101, and the second mounting ring 220 is provided with a second mounting half cavity 2203. After the first mounting ring 210 and the second mounting ring 220 are combined, the first mounting half cavity 2101 and the second mounting half cavity 2203 are combined to form a mounting cavity. The height of the mounting cavity is greater than or equal to the height of the microphone core mounting seat 300. The microphone core mounting seat 300 is placed in the mounting cavity to prevent external impact or pressure from directly acting on the microphone core mounting seat 300, and is also conducive to maintaining the correct position of the microphone core component 400 to ensure the accuracy of sound quality transmission.

[0044] In addition to tightly fixing the microphone core mounting seat 300, the first mounting ring 210 and the second mounting ring 220 can also limit and fix the microphone core mounting seat 300. Specifically, a limiting groove is provided on the side cavity wall of the mounting cavity, and a limiting portion 310 is provided on the outer peripheral wall of the microphone core mounting seat 300. The limiting portion 310 is placed in the limiting groove. Similarly, the first mounting ring 210 is provided with a first limiting groove 2102, and the second mounting ring 220 is provided with a second limiting groove 2204. After the first mounting ring 210 and the second mounting ring 220 are combined, the first limiting groove 2102 and the second limiting groove 2204 are combined to form an annular and communicating limiting groove. Furthermore, the positioning accuracy and stability of the microphone core mounting seat 300 in the mounting cavity are improved. And the limiting mechanism prevents the microphone core mounting seat 300 from moving up and down during use, ensuring the consistency and quality of audio signal collection. Optionally, the first limiting groove 2102 includes a first limiting wall surface 21021 and a second limiting wall surface 21022 that are arranged at intervals along the central line direction of the mounting cavity. Along the central line direction of the mounting cavity, the distance between the first limiting wall surface 21021 and the second limiting wall surface 21022 is equal to the height of the limiting portion 310. Thus, the first limiting wall surface 21021 and the second limiting wall surface 21022 are respectively in contact with the upper and lower end surfaces of the limiting portion 310. Similarly, the second limiting groove 2204 includes a third limiting wall surface and a fourth limiting wall surface (not shown in the figure) that are arranged at intervals along the central line direction of the mounting cavity. The third limiting wall surface and the fourth limiting wall surface are respectively in contact with the upper and lower end surfaces of the limiting portion 310. That is, the limiting groove jointly formed by the first limiting groove 2102 and the second limiting groove 2204 extends and communicates along the central line direction of the mounting cavity. The limiting portion 310 extends along the circumferential direction of the microphone core mounting seat 300, making the installation of the microphone core mounting seat 300 more convenient. During installation, there is no need to consider the rotation angle of the microphone core mounting seat 300. Only by aligning the height of the limiting groove with the limiting portion 310, the microphone core mounting seat 300 can be limited and fixed through the opposite assembly of the first mounting ring 210 and the second mounting ring 220.

[0045] Refer again to Figure 1 and Figure 3, a first mounting groove 101 and a second mounting groove 102 are provided at the top of the bracket 100. The first mounting groove 101 and the second mounting groove 102 are symmetrically arranged on the top wall of the bracket 100. The first mounting ring 210 is provided with a first fixing block 213 that is inserted and matched with the first mounting groove 101, and the second mounting ring 220 is provided with a second fixing block 221 that is inserted and matched with the second mounting groove 102, realizing a firm connection between the mounting component and the bracket 100. This design not only simplifies the fixing process of the mounting component, but also improves the stability of the overall structure. Especially when used by hand, it can effectively reduce the vibration transmission caused by holding, ensuring the clarity of audio recording. In some applications, the microphone core component 400 is installed on the microphone core mounting seat 300. After the microphone core mounting seat 300 is installed on the mounting component, the first mounting ring 210 and the second mounting ring 220 are respectively aligned with the first mounting groove 101 and the second mounting groove 102 and are inserted and installed with the bracket 100. Optionally, a sound-transmitting cover cylinder is threadedly connected to the top of the bracket 100. When the sound-transmitting cover cylinder is screwed into the top of the bracket 100, it can press and fix the first mounting ring 210 and the second mounting ring 220.

Integrating all the above technical features into the hand-held microphone forms a highly integrated, easy-to-assemble and maintain microphone core mounting solution. This comprehensive design not only optimizes the internal structure layout of the microphone, improves the portability and aesthetics of the device, but also fundamentally solves the various drawbacks of the traditional installation method, providing users with a more reliable and durable audio acquisition experience, meeting the comprehensive requirements of the modern audio device market for high quality, environmental protection and ease of use.

[0047] Other components and operations of the hand-held microphone according to an embodiment of the present invention are known to those of ordinary skill in the art and will not be described in detail here.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
