Description
Technical Field
[0001] This utility model belongs to the technical field of loudspeaker equipment accessories, specifically relating to a magnetic conductor that can be used for both internal and external magnets. Background Technology
[0002] A loudspeaker, commonly known as a "horn," is a very common electroacoustic transducer found in all sound-producing electronic and electrical equipment. The T-iron is the base of the loudspeaker and a crucial component of the speaker enclosure. The T-iron consists of the base and a magnet, which is integrally formed with the base and is a solid structure. Traditional magnets have a single function, making it essential to develop a dual-purpose magnet suitable for both internal and external magnets. Utility Model Content
[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a magnetic conductor that can be used for both internal and external magnets, comprising:
[0004] The base has a first groove; the first groove is further provided with a third recess downwards, the diameter of the third recess being smaller than that of the first groove.
[0005] A magnetic guide post, wherein a through groove is formed on the magnetic guide post, the magnetic guide post is connected to the base and the through groove is at least partially connected to the first groove;
[0006] At least one second groove is formed on the surface of the base outside the magnetic column;
[0007] The base plate has a diameter that decreases at least partially from top to bottom.
[0008] The second groove has four evenly distributed grooves, which can play a role in heat dissipation.
[0009] Both the through groove and the first groove are cylindrical. The inner walls of the through groove and the first groove are located on the same curved surface.
[0010] The base includes an integrally formed ring and a frustum, the sidewalls of which are concave inwards. The bottom surface of the frustum has an upward-facing recess.
[0011] The second groove has a gap to the outer surface of the magnetic post.
[0012] This invention can be used as a U-shaped iron by using the first groove and through groove, and can also be used by using the outer diameter of the magnetic column to form a T-shaped iron.
[0013] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, and due to the improved utilization rate of the magnetic circuit structure, the voice coil vibration is stable and the sound quality of the loudspeaker is stable.

[0018] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model concept, and are only a part of the embodiments of this utility model. The specific and direct description of related structures is only for the convenience of understanding this utility model, and the specific features do not necessarily or directly limit the scope of implementation of this utility model.
[0019] Referring to the accompanying drawings, this utility model adopts the following technical solution: This utility model provides a magnetic conductor that can be used for both internal and external magnets, comprising:
[0020] The base 1 has a first groove 2 formed on it;
[0021] A magnetic guide post 3 is provided with a through groove 4. The magnetic guide post 3 is connected to the base 1 and the through groove 4 is at least partially connected to the first groove 2.
[0022] At least one second groove 5 is formed on the surface of the base 1 outside the magnetic post 3; a third recess 6 is also formed downward from the first groove 2, and the diameter of the third recess 6 is smaller than that of the first groove 2. The first groove 2 is provided so that the bottom of the present invention is stepped, which can also increase the heat dissipation effect.
[0023] The base 1 has a diameter that decreases at least partially from top to bottom.
[0024] The second groove 5 has four grooves that are evenly distributed, which can play a role in heat dissipation.
[0025] Both the through groove 4 and the first groove 2 are cylindrical. The inner walls of the through groove 4 and the first groove 2 are located on the same curved surface.
[0026] The base 1 includes an integrally formed ring 7 and a frustum 8. The sidewall of the frustum 8 has an inwardly concave arc surface 10 to increase heat dissipation. The bottom surface of the frustum 8 has an upwardly recessed area 9 to further increase heat dissipation. The aforementioned concave arc surface 10 increases the heat dissipation area and reflects heat, preventing heat absorption.
[0027] The second groove 5 has a gap to the outer surface of the magnetic post 3.
[0028] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, and due to the improved utilization rate of the magnetic circuit structure, the voice coil vibration is stable and the sound quality of the loudspeaker is stable.
