Description

Technical Field

[0002] Chinese utility model patent (publication number: CN218416588U) discloses a magnetofluid speaker, relating to the field of audio technology. It includes a first housing, with a first fixing plate fixedly mounted on the inner surface of the first housing. A glass container is mounted on the upper end of the first fixing plate, and magnetofluid is disposed inside the glass container. A switch lighting module is mounted on the upper end of the glass container. A second fixing plate is mounted on the lower end of the first fixing plate. An electromagnetic coil, a power supply, and a main control module are sequentially mounted between the first and second fixing plates. In actual use, the permanent magnet present in the speaker itself provides auxiliary magnetism. Then, the distance between the speaker and the electromagnetic coil is adjusted to a suitable position, allowing the electromagnetic coil to generate a larger rhythmic effect from the magnetofluid with a minimum power of 3.7V. This achieves a more interesting effect while eliminating the safety hazard of overheating, enabling the device to have a smaller size, lower cost, and greater portability while maintaining the same effect.

[0003] In the aforementioned disclosed technical solution, the electromagnetic coil and the speaker are relatively close to each other. When the speaker is working, the low-frequency magnetic field generated by the energized electromagnetic coil will affect the sound quality and lifespan of the speaker. Utility Model Content

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Refer to the instruction manual appendix Figure 1-2 As shown, a novel magnetofluid audio system includes a main body 1, an electromagnet 7, a speaker 8, and a flexible iron plate 9. A transparent container 2 is mounted on the main body 1, and the transparent container 2 contains magnetofluid. The electromagnet 7 is located inside the main body 1 and below the transparent container 2. When energized, the electromagnet 7 generates a magnetic field that causes the magnetofluid to flow. The speaker 8 is located inside the main body 1. The flexible iron plate 9 is positioned between the electromagnet 7 and the speaker 8, dividing the area of ​​the electromagnet 7 and speaker 8 within the main body 1. This technical solution utilizes the flexible iron plate 9 between the speaker 8 and the electromagnet 7 to achieve this effect. It is the relative area that blocks the two, and its function is to reduce or shield the low-frequency magnetic field, thereby reducing the influence of electromagnet 7 on speaker 8, improving the sound quality of speaker 8, and extending the service life of speaker 8. Soft iron plate 9 is usually made of ultra-low carbon electrical pure iron with extremely low content of impurities such as sulfur and phosphorus to ensure high permeability and low coercivity. Soft magnet is a soft magnetic material that can be quickly magnetized under the action of an external magnetic field, and has high permeability, which can efficiently conduct magnetic field lines. After the external magnetic field is removed, the residual magnetism is very small and there is almost no magnetic residue. It is suitable for scenarios that require frequent switching of magnetic fields. When soft iron plate is used as magnetic shielding material, its high permeability can "absorb" the external magnetic field and redistribute it through the internal magnetic field lines to reduce magnetic field leakage, thereby protecting sensitive equipment.

[0024] In a preferred embodiment of this invention, the main body 1 is further provided with a power supply 6 and a main control board 10. The power supply 6 is used to provide power to the lighting module 3, the electromagnet 7 and the speaker 8, and the main control board 10 is used to control the power supply 6, the electromagnet 7, the speaker 8 and other components.

[0025] In a preferred embodiment of this invention, the main body 1 is provided with a vessel mounting groove 5, and a lighting module 3 is provided at the bottom of the vessel mounting groove 5. The transparent vessel 2 is located on the vessel mounting groove 5, and the lighting module 3 is located at the bottom of the transparent vessel 2. The lighting module 3 is a light-emitting LED. When the lighting module 3 is lit by connecting to the power supply 6, the light can shine through the transparent vessel 2 onto the magnetic fluid, thereby increasing the aesthetics of the sound.

[0026] Specifically, the vessel mounting slot 5 is provided with a vessel insertion port 51 and a lighting port 52. The transparent vessel 2 and the lighting module 3 are fixed to the vessel mounting slot 5 through the vessel insertion port 51 and the lighting port 52, respectively. In addition, the lighting module 3 is connected to the power supply 6 inside the main body 1 through the lighting port 52.

[0027] In a preferred embodiment of this invention, the main body 1 is further provided with a horn 4, and the loudspeaker 8 is located below the horn 4.

[0028] In addition, the thickness of the soft iron plate 9 is 2 mm. The bending strength of the 2 mm thick soft iron plate is about 150-200 MPa. It can withstand the installation stress and is lighter than the thicker steel plate, making it suitable for compact space layout. Moreover, the 2 mm thickness can provide sufficient magnetic flux capacity under medium magnetic field strength (such as the low-frequency interference of speakers and electromagnets) to avoid shielding failure due to magnetic saturation.

[0029] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0030] This technical solution provides a novel magnetofluid audio system, comprising a main body, an electromagnet, a speaker, and a flexible iron plate. A transparent container is mounted on the main body, and magnetofluid is disposed inside the transparent container. The electromagnet is located inside the main body and below the transparent container; when energized, the electromagnet generates a magnetic field that causes the magnetofluid to flow. The speaker is located inside the main body. The flexible iron plate is positioned between the electromagnet and the speaker, dividing the areas of the electromagnet and speaker within the main body. This technical solution, by placing a flexible iron plate between the speaker and the electromagnet, effectively isolates their relative areas, reducing or shielding low-frequency magnetic fields, thereby reducing the influence of the electromagnet on the speaker, improving the speaker's sound quality, and extending its lifespan.
