Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a tweeter assembly for an internally suspended coaxial loudspeaker with a damping ring. Background Technology

[0002] A coaxial loudspeaker is a loudspeaker design that mounts multiple loudspeaker units (usually a tweeter and a woofer) on the same axis. By mounting the woofer and tweeter on the same axis, a coaxial loudspeaker ensures that the sound comes from the same point, thus achieving a better sound field focusing effect.

[0003] Currently, the vibration components of well-known mid-high frequency loudspeakers are all externally suspended, which has excellent electroacoustic parameters and stable performance. However, its installation size cannot be made very small, so it cannot be used for coaxial loudspeakers. Internal suspension can effectively solve this problem. However, with the change of suspension method, the consistency and pass rate of indicators such as frequency response width and sound pressure uniformity have always been the main problems restricting the yield and cost. Utility Model Content

[0004] The purpose of this invention is to address the issue that, with changes in the suspension method, the consistency and pass rate of indicators such as frequency response width and sound pressure uniformity have always been major problems restricting the yield and cost of finished products. Therefore, this invention proposes a tweeter assembly for an internally suspended coaxial loudspeaker with a damping ring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tweeter assembly for an internally suspended coaxial loudspeaker with a damping ring includes a housing, a loudspeaker T-iron disposed inside the housing, a centering support attached to the top of the loudspeaker T-iron, a tweeter voice coil fixedly connected to the outside of the centering support, and a tweeter diaphragm mounted on the top of the tweeter voice coil; and further includes:

[0007] The vibration assembly includes a damping ring fixedly connected to the lower end of the tweeter diaphragm, a mounting edge fixedly connected to the outside of the damping ring, and a compensation ring fixedly connected to the inside of the damping ring. The mounting edge is connected to the tweeter voice coil.

[0008] As a preferred technical solution of this application, a fixed shell is fixedly connected to the outer surface of the speaker T-iron, and an extension column is fixedly connected to the bottom of the speaker T-iron. Threaded grooves are opened on the outer surfaces of both the fixed shell and the extension column.

[0009] As a preferred technical solution of this application, a tweeter lead is fixedly connected inside the tweeter voice coil, and a groove is provided on the upper outer side of the tweeter voice coil.

[0010] As a preferred technical solution of this application, the mounting edge is internally fixedly connected with a mounting protrusion, which matches the groove.

[0011] As a preferred technical solution of this application, the compensation ring is made of a highly elastic material.

[0012] As a preferred technical solution of this application, a magnet is fixedly connected to the bottom of the centering support plate, the bottom of the magnet is attached to the top of the speaker T-iron, and multiple wiring grooves are opened on the top of the centering support plate for placing tweeter leads. A central hole is opened inside the speaker T-iron, the centering support plate and the extension column.

[0013] As a preferred technical solution of this application, the top of the outer shell is provided with a through hole, and the lower inner side of the outer shell is provided with a thread, and the thread matches the thread groove.

[0014] Compared with the prior art, this utility model provides a tweeter assembly for an internally suspended coaxial loudspeaker with a damping ring, which has the following advantages:

[0015] 1. Through the set vibration component, the tweeter voice coil vibrates when driven by an electrical signal. This vibration does not directly drive the tweeter diaphragm to produce sound, but is transmitted to the tweeter diaphragm through the damping ring. The good damping characteristics of the damping ring effectively control the frequency range and sound pressure uniformity of the diaphragm vibration, thereby improving performance, increasing consistency and thus increasing the yield.

[0016] 2. The fixed housing, extension column, and threaded groove design facilitate the installation of the device in a designated location. The magnets facilitate the installation of the centering support and speaker T-iron, while the wiring grooves facilitate the arrangement of the tweeter leads. The housing completely covers the device to maintain a tight fit, improving the overall stability and ease of installation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Reference Figure 1-5 A tweeter assembly with a damping ring and an internally suspended coaxial loudspeaker includes a housing 1, a loudspeaker T-iron 2 disposed inside the housing 1, a centering support 7 attached to the top of the loudspeaker T-iron 2, a tweeter voice coil 3 fixedly connected to the outside of the centering support 7, and a tweeter diaphragm 5 mounted on the top of the tweeter voice coil 3. It also includes a vibration assembly and a mounting assembly. The vibration assembly includes a damping ring 501 fixedly connected to the lower end of the tweeter diaphragm 5, a mounting edge 502 fixedly connected to the outside of the damping ring 501, and a compensation ring 503 fixedly connected to the inside of the damping ring 501. The mounting edge 502 is connected to the tweeter voice coil 3. The mounting assembly is disposed outside the loudspeaker T-iron 2 and is used for assembling and fixing the device.

[0027] The mounting bracket 502 is fitted onto the top of the tweeter voice coil 3, while the centering support 7 is supported inside the tweeter voice coil 3 for centering vibration support, thus forming a voice coil diaphragm assembly. It should be noted that the centering support 7 is a sponge-like material with a certain degree of elasticity, possessing the bouncy properties of the centering support 7. When the tweeter voice coil 3 vibrates, the vibration is transmitted to the tweeter diaphragm 5 through the damping ring 501. The excellent damping characteristics of the damping ring 501 effectively control the frequency range and sound pressure uniformity of the diaphragm vibration. The damping ring 501 can be made of synthetic rubber or foam material with high viscoelasticity to ensure its excellent damping characteristics. The mounting assembly can connect multiple dispersed parts such as the tweeter voice coil 3, the speaker T-iron 2, and the vibration assembly together, facilitating the installation, disassembly, and maintenance of the equipment.

[0028] Reference Figure 2 and Figure 3 A tweeter assembly of an internally suspended coaxial loudspeaker with a damping ring is further provided. The outer surface of the loudspeaker T-iron 2 is fixedly connected to a fixed shell 201, and the bottom of the loudspeaker T-iron 2 is fixedly connected to an extension post 202. The outer surfaces of the fixed shell 201 and the extension post 202 are both provided with threaded grooves 203. The top of the outer shell 1 is provided with a through hole, and the lower inner side of the outer shell 1 is provided with threads, and the threads match the threaded grooves 203.

[0029] The main function of the speaker T-iron 2 is to conduct magnetism when energized, but it has no residual magnetism. During installation, the speaker T-iron 2 is inserted into the inside of the tweeter voice coil 3, and then the outer shell 1 is connected to the fixed shell 201 using the threaded groove 203. This can maintain the tightness of the connection between the speaker T-iron 2 and other parts. The extension post 202 can install the speaker T-iron 2 on the speaker base for easy disassembly.

[0030] Reference Figure 4 and Figure 5 A tweeter assembly for an internally suspended coaxial loudspeaker with a damping ring is further characterized by a tweeter lead wire 4 fixedly connected inside the tweeter voice coil 3, and a groove 6 formed on the upper outer side of the tweeter voice coil 3; a mounting protrusion 504 fixedly connected inside the mounting edge 502, which matches the groove 6; and a compensation ring 503 made of a highly elastic material, which can absorb and reduce local distortion of the tweeter voice coil 3 during high-frequency vibration.

[0031] The lower end of the tweeter lead 4 is connected to the tweeter terminal block to facilitate signal reception by the tweeter voice coil 3. When installing the damping ring 501, the mounting protrusion 504 will engage with the inside of the groove 6 to maintain installation stability. The compensation ring 503 is usually made of a highly elastic material such as elastic rubber, silicone, or other materials with good resilience and density, and has good thickness and density. When the tweeter voice coil 3 vibrates, due to the change of the excitation signal and the interaction between the voice coil and other parts of the speaker, an uneven vibration mode will be generated. This uneven vibration often leads to distortion in the sound frequency response. When the tweeter voice coil 3 generates uneven vibration, the compensation ring 503 can absorb and disperse these distortions, reducing sound quality problems caused by vibration imbalance.

[0032] Among them, the bottom of the centering support plate 7 is fixedly connected to a magnet 701, the bottom of the magnet 701 is attached to the top of the speaker T iron 2, and the top of the centering support plate 7 is provided with multiple wiring grooves 702 for placing the tweeter lead wire 4. The speaker T iron 2, the centering support plate 7 and the extension column 202 are all provided with a center hole 8.

[0033] The tweeter lead 4 runs along the inner wall of the tweeter voice coil 3 to the top of the centering support 7, then passes through the center hole 8 of the centering support 7, and then through the center hole 8 of the speaker T-iron 2 and the extension post 202. The lower end of the tweeter lead 4 is connected to the tweeter terminal block to facilitate the tweeter voice coil 3 in receiving signals. The wiring groove 702 facilitates the arrangement of the tweeter lead 4 and reduces the shaking of the lead during use.

[0034] Specifically, in use, the present invention is as follows: First, the speaker T-iron 2 is inserted into the inside of the tweeter voice coil 3. The centering support 7 and the speaker T-iron 2 are connected using the magnet 701. Then, the tweeter lead 4 passes through the center hole 8 of the centering support 7, and then through the center hole 8 of the speaker T-iron 2 and the extension post 202. The lower end of the tweeter lead 4 is then connected to the tweeter terminal block. Next, the damping ring 501 is installed on the top of the tweeter voice coil 3 via the mounting edge 502. The mounting protrusion 504 engages with the groove 6 to maintain stable installation. Finally, the assembled components are inserted into the inside of the housing 1 and secured by the threaded groove 203. Tighten the screws and then use the extension post 202 to install the entire device inside the speaker, which facilitates the installation and disassembly of the device. During operation, the tweeter voice coil 3 receives an electrical signal through the tweeter lead 4 to drive it to vibrate. When the tweeter voice coil 3 vibrates, it transmits the vibration to the tweeter diaphragm 5 through the damping ring 501. The good damping characteristics of the damping ring 501 effectively control the frequency range and sound pressure uniformity of the diaphragm vibration. When the tweeter voice coil 3 vibrates unevenly, the compensation ring 503 can absorb and disperse these distortions, reduce the sound quality problems caused by vibration imbalance, thereby improving performance, increasing consistency and thus increasing the yield.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
