Description

Technical Field

[0001] This utility model relates to the field of T-iron technology, specifically to an adjustable gap T-iron structure. Background Technology

[0002] As an electroacoustic device, a loudspeaker needs to have good frequency response, low distortion, and high efficiency. The magnetic circuit system is one of the core components of a loudspeaker. The T-iron forms the main body of the magnetic circuit, guides the flow of magnetic flux, and directly affects the performance of the loudspeaker.

[0003] The air gap size of traditional magnetic circuits is fixed after design and manufacturing, and cannot be adjusted according to actual needs. This limits the performance optimization and application range of loudspeakers to a certain extent, and has certain limitations. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides an adjustable gap T-iron structure to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable gap T-iron structure, including a base, a T-iron body mounted on the top of the base, a permanent magnet mounted on the outer side of the T-iron body, a guide post mounted inside the T-iron body, the guide post being threadedly connected to the bottom of the base via a second locking screw, and an adjusting screw connected to the top of the guide post.

[0008] Preferably, a plurality of first locking screws are distributed around the outer circumference of the base, and the top of the first locking screws is embedded inside the base.

[0009] Preferably, an upper electrode plate is installed on the outer side of the adjusting screw, and the upper electrode plate is a circular metal plate.

[0010] Preferably, a non-magnetic pad is installed between the upper electrode and the permanent magnet, and the non-magnetic pad is made of rubber.

[0011] Preferably, nuts are installed at the top and bottom of the upper electrode, and washers are provided inside the nuts. The washers are circular thin sheets.

[0012] Compared with the prior art, this utility model provides an adjustable gap T-iron structure with the following beneficial effects: In this adjustable gap T-iron structure, the T-iron body is used to support the permanent magnet and guide the magnetic lines of force to the air gap. The guide post connects the upper pole piece and the T-iron body, providing structural support and ensuring that the upper pole piece remains parallel during adjustment. The adjusting screw adjusts the gap between the upper pole piece and the permanent magnet. The circumferentially distributed first locking screw is used to disperse stress. The non-magnetic pad isolates the upper pole piece and the permanent magnet, reduces the friction between the locking nut and the upper pole piece, increases the contact area, disperses pressure, and prevents damage to the surface of the upper pole piece.

[0017] 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.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: an adjustable gap T-iron structure, including a base 1, a T-iron body 2 installed on the top of the base 1, a permanent magnet 3 installed on the outside of the T-iron body 2, a guide post 9 installed inside the T-iron body 2, the guide post 9 being threadedly connected to the bottom of the base 1 by a second locking screw 8, and an adjusting screw 6 connected to the top of the guide post 9.

[0019] Furthermore, several first locking screws 7 are distributed around the outer circumference of the base 1, with the top of the first locking screws 7 embedded inside the base 1.

[0020] Specifically, the circumferentially distributed first locking screw 7 can evenly distribute stress, reduce local stress concentration, and enhance the overall structure's durability and load-bearing capacity.

[0021] Furthermore, an upper electrode plate 5 is installed on the outside of the adjusting screw 6, and the upper electrode plate 5 is a circular metal plate.
