Description

Technical Field

[0001] This application relates to the field of acoustic engineering technology, and more specifically, to an audio resonator. Background Technology

[0002] An audio resonator works by inputting an audio signal to a voice coil. The magnetic field generated by the voice coil interacts with the magnetic field of a magnetic block, driving the centering support to move and thus inducing vibration in the physical medium.

In existing technology, a thin-walled tubular structure with a wound voice coil wire is typically vertically bonded to an aluminum alloy cap. However, during long-term use, high-frequency vibrations can easily loosen the adhesive layer between the thin-walled tubular structure and the aluminum alloy cap, leading to voice coil detachment and voice coil wire breakage, ultimately causing equipment failure.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] An audio resonator works by inputting an audio signal to the voice coil 104. The magnetic field generated by the voice coil 104 interacts with the magnetic field of the magnetic block, driving the centering support to move and thus inducing vibration in the physical medium. The audio resonator can amplify certain frequencies of sound using the principle of physical resonance, achieving precise control and optimization of sound characteristics. In existing technology, a thin-walled tubular structure 102 with the voice coil 104 wire wound around it is typically vertically bonded to an aluminum alloy cover. However, during long-term use, high-frequency vibrations can easily cause the adhesive layer between the thin-walled tubular structure 102 and the aluminum alloy cover to loosen, leading to malfunctions such as the voice coil 104 detaching or the voice coil 104 wire breaking, ultimately causing equipment failure.

[0029] To address the aforementioned technical problems, this application provides an audio resonator.

[0030] Reference Figure 1 , Figure 2 As shown, this application provides an audio resonator, including a first cover 100, a second cover 101, and a tubular structure 102; the first cover 100 and the second cover 101 are fastened together to form an installation chamber; the first cover 100 is provided with a recessed structure 103 facing the second cover 101; the first end of the tubular structure 102 is inserted into the recessed structure 103, and the second end extends toward the second cover 101; a voice coil 104 is sleeved on the outer wall of the second end of the tubular structure 102.

[0031] In this embodiment, a vibration fixing plate 112 is provided in the installation chamber, and the plane of the vibration fixing plate 112 is perpendicular to the central axis of the pipe structure 102; a magnetic ring 113 is provided on the vibration fixing plate 112, and the voice coil 104 is close to the magnetic ring 113.

[0032] It should be noted that, in this embodiment, the first cover 100 and the second cover 101 are fastened together to form a closed installation chamber. This design not only provides robust mechanical support but also effectively protects the internal components from the influence of the external environment.

[0033] It should be noted that, in this embodiment of the application, a recessed structure 103 is provided on the first cover 100 facing the second cover 101. The opening of the recessed structure 103 faces the second cover 101. The recessed structure 103 is used to accommodate and fix the first end of the pipe structure 102, ensuring the stability of the position of the pipe structure 102 and avoiding the problems that may be caused by the use of glue in traditional methods.

[0034] It should be noted that the first end of the pipe structure 102 is tightly inserted into the recessed structure 103 on the first cover 100, rather than being simply bonded with glue, thereby improving the reliability and stability of the connection. Alternatively, the outer wall of the first end of the pipe structure 102 can be glued to the inner wall of the recessed structure 103 as needed. In this embodiment, the glue bonding of the outer wall of the first end to the inner wall of the recessed structure 103 provides a large bonding area, further strengthening the fixing effect and effectively preventing the pipe structure 102 from detaching.

[0035] The second end of the tube structure 102 in this embodiment extends toward the second cover 101. This provides sufficient space for the voice coil 104 and ensures that the voice coil 104 has enough space to move, while maintaining the consistency and stability of the entire structure.

[0036] In this embodiment, a voice coil 104 is fitted on the outer wall of the second end of the pipe structure 102. When the voice coil 104 is energized, it generates a magnetic field, which interacts with the magnetic field of the magnetic block, causing the centering support near the second end of the pipe structure 102 to vibrate, thereby driving the physical medium to produce sound.

[0037] The technical effects that the embodiments of this application can produce are as follows:

[0038] Improved connection reliability: By using a recessed structure 103 to fix the pipe structure 102 instead of the traditional glue bonding method, the risk of the adhesive layer loosening due to long-term high-frequency vibration is greatly reduced, thereby improving the overall reliability and service life of the equipment.

[0039] Enhanced structural stability: The recessed structure 103 provides more stable support for the tubular structure 102, ensuring that it will not shift or deform during long-term use, which is crucial for maintaining consistent sound quality.

[0040] To prevent the voice coil 104 from falling off or breaking: Because the connection between the tube structure 102 and the cover is more secure, this directly reduces the risk of the voice coil 104 falling off due to vibration or the voice coil 104 wire breaking, ensuring the normal operation and performance of the equipment.

[0041] Optimized acoustic performance: A robust mechanical structure helps reduce unnecessary vibration losses, allowing more energy to be converted into effective sound output, thus improving overall acoustic performance and efficiency.

[0042] In summary, the embodiments of this application significantly improve the mechanical stability and reliability of the device by improving the traditional audio resonator structure, especially by introducing a recessed structure 103 on the first cover 100 to replace glue bonding in fixing the tube structure 102. This effectively solves the malfunction problems that may occur during long-term use and also helps to optimize acoustic performance.

[0043] Reference Figure 3 , Figure 4 As shown, in one optional embodiment, the second cover 101 has a slot 105 with an opening facing the first cover 100. A terminal adapter plate 106 is provided in the slot 105, and the voice coil wire led out from the voice coil 104 is connected to the pin 107 on the terminal adapter plate 106.

[0044] It should be noted that, in this embodiment of the application, a slot 105 with an opening facing the first cover 100 is designed on the second cover 101. This slot 105 is used to accommodate and fix the terminal adapter plate 106, ensuring its accurate and stable position. In this embodiment of the application, the terminal adapter plate 106 is precisely embedded in the slot 105. The embedded design not only provides solid mechanical support but also protects the electronic components from the influence of the external environment.

[0045] In this configuration, the voice coil 104 extends from the end of the tubular structure 102 and is directly connected to the pin 107 on the terminal adapter plate 106. This connection method ensures that electrical signals can be transmitted to the voice coil 104 efficiently and stably, driving the voice coil 104 to generate the required magnetic field to drive the centering support to vibrate.

[0046] The beneficial effects that the embodiments of this application can produce are as follows:

[0047] The modular design of this embodiment facilitates subsequent maintenance and repair. If the voice coil 104 or the terminal adapter board 106 needs to be replaced, only the corresponding components need to be disassembled, without the need for large-scale disassembly of the entire device, thus improving the ease of maintenance and the replaceability of components.

[0048] The pin 107 design in this embodiment ensures the shortest possible electrical signal transmission path and minimizes resistance, thereby improving signal transmission efficiency and reducing energy loss. This is crucial for ensuring consistent sound quality and high-performance output.

[0049] The design of embedding the terminal adapter board 106 into the slot 105 in this embodiment not only saves space but also improves the overall compactness and integration of the device, which helps to reduce the size of the device and adapt to more application scenarios.

[0050] Reference Figure 2 As shown, in one optional embodiment, the first cover 100 is provided with a protrusion 108 extending toward the second cover 101; when the first cover 100 and the second cover 101 are fastened together, one side of the terminal adapter plate 106 abuts against the protrusion 108, and the other side abuts against the inner wall of the slot 105.

[0051] It should be noted that, in this embodiment of the application, a protrusion 108 extending toward the second cover 101 is designed on the first cover 100. The position of this protrusion 108 corresponds to the terminal adapter plate 106, ensuring that it can contact and provide support to the terminal adapter plate 106 when the first cover 100 and the second cover 101 are fastened together. When the first cover 100 and the second cover 101 are fastened together, the terminal adapter plate 106 is sandwiched between them. Specifically, one side of the terminal adapter plate 106 abuts against the protrusion 108 on the first cover 100, while the other side is in close contact with the inner wall of the slot 105 on the second cover 101. This double-sided support design ensures the stability and positional accuracy of the terminal adapter plate 106.

[0052] The terminal adapter plate 106 in this embodiment achieves dual support through the protrusion 108 and the inner wall of the slot 105, forming a mechanically fixed structure. This not only enhances the stability of the terminal adapter plate 106, but also prevents it from shifting or loosening due to vibration or external force during equipment operation.

[0053] Therefore, in this embodiment, the protrusion 108 and the inner wall of the slot 105 work together to provide stable support for the terminal adapter plate 106. This design significantly reduces the risk of the terminal adapter plate 106 loosening or shifting due to long-term high-frequency vibration, and improves the overall reliability and durability of the equipment.

[0054] Reference Figure 3 , Figure 4 As shown, in one optional implementation, the card slot 105 is provided with positioning posts 109 on both sides; the terminal adapter plate 106 is provided with positioning holes 110; the positioning posts 109 are inserted into the positioning holes 110 respectively.

[0055] It should be noted that the terminal adapter plate 106 of this application has positioning holes 110, the positions of which match the positioning posts 109 on both sides of the slot 105. When the first cover 100 and the second cover 101 are engaged, the positioning posts 109 will be inserted into the corresponding positioning holes 110 to achieve precise positioning.

[0056] In this embodiment, the insertion and engagement of the positioning post 109 with the positioning hole 110 ensures accurate alignment of the terminal adapter plate 106 during installation, reducing human error. This precise positioning mechanism helps improve assembly consistency and reliability, which is particularly important in mass production.

[0057] The insertion design of the positioning post 109 and the positioning hole 110 in this embodiment provides additional mechanical support and fixation for the terminal adapter plate 106. This not only enhances the stability of the terminal adapter plate 106 during equipment operation, but also effectively prevents displacement or loosening caused by vibration or external forces, thereby improving the overall reliability and durability of the equipment.

[0058] This plug-in design in the embodiments of this application makes the installation of the terminal adapter plate 106 simpler and faster. Installation is completed simply by aligning the positioning hole 110 with the positioning post 109 and gently inserting it, without the need for complex adjustment steps. This design greatly simplifies the assembly process and reduces operational difficulty and error rate.

[0059] Reference Figure 4 As shown, in one optional implementation, the terminal adapter plate 106 is provided with a plug-in terminal 111; the second cover 101 has an opening that communicates with the slot 105 to allow the plug-in terminal 111 to be exposed.

[0060] It should be noted that, in this embodiment of the application, a clearance opening communicating with the slot 105 is provided on the second cover 101. The position and size design of the clearance opening ensures that the plug-in terminal 111 can pass through from the inside and be exposed to the outside of the device, thereby facilitating connection with other external components.

[0061] It should be noted that the plug-in terminal 111, through its design that avoids exposing the opening, allows external circuitry to be directly connected to the voice coil 104 inside the audio resonator without the need for additional complex wiring or interface conversion devices.

[0062] The embodiments of this application ensure the directness and stability of the electrical connection through the exposed plug-in terminal 111 design. Compared with traditional indirect connection methods, this design reduces contact resistance and potential contact problems, and improves the reliability and consistency of signal transmission.

[0063] Reference Figure 1 , Figure 5As shown, in one optional implementation, the installation chamber of this application embodiment is provided with a vibration fixing plate 112, the plane of which is located is perpendicular to the central axis of the pipe structure 102; one side of the magnetic ring 113 is bonded to the vibration fixing plate 112, and the other side is bonded to a magnetic ring seat 114; a damping layer 115 is bonded to the side of the magnetic ring seat 114 away from the magnetic ring 113; the damping layer 115 does not directly contact the second cover 101. The vibration fixing plate 112 is sandwiched between the first cover 100 and the second cover 101.

[0064] It should be noted that in this embodiment, one side of the magnetic ring 113 is bonded to the vibration fixing plate 112, and the other side is bonded to the magnetic ring seat 114. This design not only ensures the stability of the magnetic ring 113, but also provides the necessary mechanical support to prevent the magnetic ring 113 from shifting or loosening due to vibration.

[0065] In this embodiment, a damping layer 115 is bonded to the side of the magnetic ring seat 114 away from the magnetic ring 113. This damping layer 115 does not directly contact the second cover 101 and is suspended. The function of the damping layer 115 is to absorb and disperse the energy generated by high-frequency vibration, reduce the amount of vibration transmitted to the equipment casing, and thus reduce the impact of noise and vibration on the equipment performance.

[0066] It should be noted that the vibration fixing plate 112 is sandwiched between the first cover 100 and the second cover 101 to ensure that its position in the whole equipment is fixed and stable and is not affected by external factors.

[0067] The technical effects that can be achieved through the above settings are:

[0068] The damping layer 115 in this embodiment effectively absorbs the energy of high-frequency vibrations, reducing unnecessary vibration transmission to the device housing or other components. This design helps maintain the purity of sound output, avoiding sound distortion or noise problems caused by additional vibrations, thereby improving sound quality.

[0069] The embodiments of this application can reduce the relative movement and vibration between internal components, which can significantly reduce the wear rate and extend the service life of key components such as the magnetic ring 113 and the voice coil 104. This is especially important for audio equipment used for a long time, as it helps to reduce maintenance costs and replacement frequency.

[0070] This application embodiment optimizes the magnetic field distribution and improves driving efficiency by precisely controlling the position and interaction of each component, particularly the relationship between the magnetic ring 113 and the voice coil 104. This not only enhances the intensity and clarity of the sound output but also improves the low-frequency response and overall sound field performance.

[0071] The presence of the damping layer 115 in this embodiment greatly enhances the vibration resistance of the equipment, especially in high-frequency vibration environments, effectively reducing the risk of failure caused by vibration. This design makes the equipment more suitable for use in complex and variable working environments, such as mobile devices or vehicle audio systems.

[0072] As an optional implementation, the vibration fixing plate 112 includes an injection-molded structural component and a carbon steel structural component embedded in the injection-molded structural component.

[0073] It should be noted that existing technologies typically use stainless steel as the housing or supporting component of audio resonators. However, stainless steel has relatively weak fatigue resistance and high-temperature resistance, making it prone to breakage during long-term operation and under high-temperature environments. This can easily lead to the failure of the resonant speaker, resulting in a short lifespan and high operating costs.

[0074] This application embodiment employs an injection-molded structural component embedded with a carbon steel structural component. The injection-molded component material can be selected from a wide range of toughness and strength parameters, effectively addressing the issue of insufficient toughness in stainless steel after durability vibration testing. Therefore, this design can further extend the service life of the audio resonator.

[0075] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, in one optional embodiment, the first cover 100 and the second cover 101 are respectively provided with a first connecting part 116 and a second connecting part 117, and the vibration fixing plate 112 is provided with a connecting ear 118; it also includes a locking member 119, which is sequentially passed through the first connecting part 116, the connecting ear 118 and the second connecting part 117, for locking the first cover 100 and the second cover 101.

[0076] The above settings enable quick assembly and disassembly, which not only facilitates mass production but also makes subsequent maintenance convenient.

[0077] Furthermore, both the first cover 100 and the second cover 101 are provided with heat dissipation holes.

[0078] The embodiments of this application can effectively enhance the heat dissipation capacity of the audio resonator by setting heat dissipation holes, and avoid overheating damage during long-term use of the device.

[0079] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
