Technical Field

[0001] The utility model belongs to the technical field of tweeters, and in particular relates to a T-iron structure for tweeters. Background Art

However, with the development of the times, most of the T-irons on the market have improved the heat dissipation system, modifying it into a structure consisting of a solid base, a solid pole core fixedly connected to the base, and a heat dissipation hole running through the base and the pole core.

[0003] Therefore, a new T-iron structure is designed, which still overcomes the problem of "the integrated structure is inconvenient to repair and replace" on the basis of the existing technology, and improves the effect of heat dissipation performance. Utility Model Content

[0004] The purpose of the utility model is to provide a T-iron structure for a tweeter to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a T-iron structure for a tweeter, comprising a base and a magnetic conductor, the base being connected to the magnetic conductor through a heat dissipation channel, a mounting ring being provided on the inner wall of the base, a plurality of limit grooves being provided in the mounting ring, limit blocks being symmetrically provided on the lower part of the magnetic conductor, and a plurality of heat dissipation holes being connected between the mounting ring and the base.

[0006] Preferably, a baffle is provided in the mounting ring via a spring sliding.

[0007] Preferably, the baffle is located above the limiting groove, and the height of the baffle is greater than that of the limiting block.

[0008] Preferably, the number of the heat dissipation holes is the same as that of the limiting grooves, and ventilation ducts are connected to each other.

[0009] Preferably, the bottom of the heat dissipation channel is inclined.

[0010] Preferably, a cooling block is provided between the heat dissipation channel and the base.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a limit block at the lower part of the magnetic conductor, and then inserts the limit block into the limit groove on the base, thereby realizing rapid installation and disassembly of the magnetic conductor, so that when the T iron is damaged, there is no need to replace all of them, and they can be replaced individually after damage, thereby reducing maintenance costs; and through the heat dissipation holes that penetrate the base and the mounting ring, further dissipation of heat is achieved, and at the same time, the limit groove and the heat dissipation holes are intermittently arranged, so that each heat dissipation hole can be connected to the limit groove at an equal distance, dissipating heat evenly and improving heat dissipation performance.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figures 1 to 4 A T-iron structure for a tweeter shown in the figure includes a base 1 and a magnetizer 2. The base 1 is connected to the magnetizer 2 through a heat dissipation channel 3. A mounting ring 4 is provided on the inner wall of the base 1. A plurality of limiting grooves 5 are opened in the mounting ring 4. Limiting blocks 6 are symmetrically provided at the lower part of the magnetizer 2. A plurality of heat dissipation holes 7 are connected between the mounting ring 4 and the base 1. A baffle 9 is slidably provided in the mounting ring 4 through a spring 8. The baffle 9 is located above the limiting groove 5, and the height of the baffle 9 is greater than the limiting block 6. The number of heat dissipation holes 7 is the same as that of the limiting groove 5, and a ventilation duct 10 is connected between them. The bottom of the heat dissipation channel 3 is inclined. A cooling block 11 is provided between the heat dissipation channel 3 and the base 1.

[0020] The utility model realizes the rapid installation and disassembly of the magnetizer 2 by arranging a limit block 6 at the lower part of the magnetizer 2, and then inserting the limit block 6 into the limit groove 5 on the base 1, so that when the T iron is damaged, there is no need to replace all of them, and they can be replaced individually after damage, thereby reducing the maintenance cost; and through the heat dissipation holes 7 that penetrate the base 1 and the mounting ring 4, the heat is further dissipated, and at the same time, the limit groove 5 and the heat dissipation holes 7 are intermittently arranged, so that each heat dissipation hole 7 can be connected to the limit groove 5 at an equal distance, the heat is evenly dissipated, and the heat dissipation performance is improved.

[0021] Example 2

[0022] like Figures 1 to 4 The T-iron structure for a tweeter shown in the figure includes a base 1 and a magnet 2. The base 1 is hollow and connected to the magnet 2 through a heat dissipation channel 3. The magnet 2 is also hollow. Only after the two are installed can a through heat dissipation channel 3 be formed to ensure its basic heat dissipation function. In order to realize a detachable T-iron structure, a mounting ring 4 is provided on the inner wall of the middle part of the base 1, and a plurality of limit grooves 5 are provided on the installation. Correspondingly, a limit block 6 is also provided at the lower part of the magnet 2. By inserting the limit block 6 into the limit groove 5, the magnet 2 can be quickly installed.

[0023] Specifically, the limiting groove 5 and the limiting block 6 are set correspondingly, and the shapes and quantities must correspond to each other. For example, in this embodiment, the limiting groove 5 and the limiting block 6 should both be circular grooves and cylinders, so that the cylinder can be inserted into the circular groove and the magnetizer 2 can be fixedly installed on the base 1; the staff can also replace the limiting block 6 with a polygon, and the corresponding shape of the limiting groove 5 also needs to be changed. In this embodiment, the production cost and process of the polygon are more complicated than those of the cylinder. Therefore, the circular groove and cylindrical limiting block 6 are selected for use without affecting its basic function. The specific setting quantity of the limiting groove 5 and the limiting block 6 needs to be set according to the following rules: the number of the limiting grooves 5 must be a multiple of the limiting block 6, so that the limiting block 6 can be easily inserted into the limiting groove 5 without careful alignment, thereby improving the actual use feeling; then, in this embodiment, the number of limiting blocks 6 is 2, which is the lowest common multiple in the number combination, and can easily adapt to a variety of numbers of limiting grooves 5.

[0024] Furthermore, a through groove is provided above the inner wall of the limit groove 5 for slidingly installing a baffle 9. A plurality of springs 8 are connected between the outer side of the baffle 9 and the inner wall of the through groove. In the initial state, the baffle 9 moves outward under the action of the springs 8. The overall appearance of the baffle 9 is set to be smooth, so that when the magnet 2 is installed, the limit block 6 on it can be driven to move downward into the limit groove 5 together, and the limit block 6 moves downward to squeeze the baffle 9 outward into the through groove; since the height of the baffle 9 is set to be higher than the height of the limit block 6 after the magnet 2 is installed, when the magnet 2 is installed, the baffle 9 is no longer squeezed, and moves out of the through groove again under the resetting action of the spring 8, and limits the limit block 6, so as to prevent the magnet 2 from moving upward out of the limit groove 5 due to the vibration force when the speaker is operating, causing internal failure.

[0025] Example 3

[0026] like Figures 1 to 4 The T-iron structure for a tweeter shown includes a plurality of heat dissipation holes 7 provided on a mounting ring 4, and the heat dissipation holes 7 also penetrate the base 1, and are used to dissipate heat when the T-iron is in operation. Referring to Example 2, when the magnetic conductor 2 is inserted into the limiting groove 5 through the limiting block 6 for connection and installation with the base 1, the remaining limiting groove 5 is idle, and the limiting groove 5 can be fully utilized, and the limiting groove 5 is connected with the heat dissipation holes 7 to increase the heat overflow port, thereby improving the heat dissipation performance; therefore, the number of heat dissipation holes 7 is set to be consistent with the limiting groove 5, and the two are intermittently arranged, so that each heat dissipation hole 7 can be connected with the limiting groove 5 at an equal distance, and the heat is evenly dissipated.

[0027] It should be noted that the bottom of the heat dissipation channel 3 is arranged to extend inwardly at an angle, which can guide the heat and make it pass through the heat dissipation channel 3 faster; and a cooling block 11 is also arranged between the heat dissipation channel 3 and the base 1, which can be used to cool the passing heat and effectively improve the heat dissipation speed, wherein the cooling block 11 can be made of any non-magnetic material to prevent it from reacting with the T iron and affecting the operation of the speaker.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0029] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
