Technical Field
[0001] This utility model relates to the field of loudspeaker technology, and in particular to a novel square multi-magnetic aluminum diaphragm coaxial high and low frequency dual-effect loudspeaker. Background Technology
[0002] Currently, most speakers on the market use a structure design with independent tweeters and woofers to meet different performance requirements for high-frequency and low-frequency sound effects. While this design has certain advantages in sound performance, it is often structurally complex and takes up a lot of space, making it difficult to adapt to terminal products with high requirements for size and compactness, such as smartphones, tablets, and laptops. At the same time, in order to achieve high-fidelity output across multiple frequency bands, traditional designs usually require two or more sound units to be distributed and installed, which not only increases the size of the product but also easily causes phase deviation due to inconsistent high and low frequency sound positions, affecting the sense of layering and positioning of the sound. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a novel square multi-magnetic aluminum diaphragm coaxial high and low frequency dual-effect loudspeaker, which aims to improve the problem that the traditional design in the prior art usually requires two or more sound units to be installed in a distributed manner, which not only increases the product size, but also easily causes phase deviation due to inconsistent high and low frequency sound positions, affecting the sense of layering and positioning of the sound.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A novel square multi-magnetic aluminum diaphragm coaxial high- and low-frequency dual-effect loudspeaker includes:
[0006] support;
[0007] A large diaphragm, which is mounted on top of the bracket;
[0008] A small magnet and a T-shaped iron are fixedly connected to the top of the large diaphragm.

[0011] Furthermore, a large U-cup is fixedly connected to the lower part of the bracket, and a large voice coil is installed at the lower part of the large U-cup.
[0012] Furthermore, long-side magnets are installed on both sides of the lower part of the large voice coil, and segmented-side magnets are provided on both sides of the lower part of the two long-side magnets.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1 This utility model provides one embodiment: a novel square multi-magnetic aluminum diaphragm coaxial high-low dual-effect loudspeaker, comprising: a bracket 8; a large diaphragm 9, mounted on top of the bracket 8; a small magnet 10 and a T-iron 11, the small magnet 10 being fixedly connected to the top of the large diaphragm 9 to provide the driving magnetic field for the tweeter, and the T-iron 11 being fixedly connected to the top of the small magnet 10; optimized magnetic circuit distribution to enhance magnetic field utilization; a ring washer 12 and a small voice coil 13, the ring washer 12 being sleeved outside the T-iron 11 to further equalize the magnetic lines of force and reduce high-frequency distortion, and the small voice coil 13 being mounted in the middle of the ring washer 12; a small diaphragm 14, fixedly connected to the top of the small voice coil 13, responsible for high-frequency response; a large U-cup 7 fixedly connected to the lower part of the bracket 8, and a large voice coil 5 installed below the large U-cup 7 to enhance low frequencies. For radiation efficiency, long-side magnets 4 are installed on both sides of the lower part of the large voice coil 5. Segmented magnets 3 are set on both sides of the lower part of the two long-side magnets 4. Pin pads 2 are set in the middle of the two segmented magnets 3. The bottom of the pin pads 2 is fixedly connected to the back cover 1 to seal the bottom of the speaker. A diaphragm steel ring 15 is installed on the top of the small diaphragm 14 to provide rigid support and prevent high-frequency vibration distortion. A small protective cover 16 is fixedly connected to the top of the diaphragm steel ring 15 to cover the tweeter, protect the small diaphragm 14 and optimize the high-frequency sound wave diffusion. Solder pads 6 are installed on both sides of the middle of the large voice coil 5 and the large U cup 7 to ensure stable transmission of electrical signals. There are two segmented magnets 3 and two long-side magnets 4. By arranging two segmented magnets 3 and two long-side magnets 4 around the speaker, a symmetrical multi-magnetic structure is formed, which can create a stronger and more uniform magnetic field in the voice coil movement area.
[0025] Working principle: This square multi-magnetic aluminum diaphragm coaxial high and low frequency dual-effect speaker adopts a coaxial structure design, with the tweeter nested in the center of the woofer. By sharing a common axis, high and low frequencies are coordinated. The tweeter is driven by a small voice coil 13 to drive a small diaphragm 14, generating high-frequency sound waves in a local magnetic field. The woofer is driven by a large voice coil 5 to drive a large diaphragm 9, emitting low-frequency sound waves in a strong magnetic field enhanced by the multi-magnetic structure. Through coaxial integration, the sound propagation path is ensured to be consistent, effectively avoiding high and low frequency phase deviation, thereby improving the clarity, positioning and overall sound quality of the sound field.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
