Description

Technical Field

[0001] The utility model belongs to the technical field of sound generators and the technical field of accessories, and specifically relates to a convex font speaker T iron. Background Art

[0002] The T-iron is the base of the speaker and is a relatively important part of the speaker. The T-iron includes a base and a magnet. The magnet is made integrally with the base and is a solid structure.

[0003] The traditional T-iron has the following problems: 1. Poor heat dissipation. Since the magnetic conductor is solid, the T-iron has poor heat dissipation. 2. Low magnetic force utilization rate. Due to the large cross-sectional area of ​​the T-iron, a part of the magnetic force is wasted, so that the magnetic force is not fully utilized, resulting in a decrease in the sensitivity of the speaker. 3. Large volume. Since the height of the magnetic conductor is determined according to the design requirements, the height of the entire T-iron is relatively high, which not only has a large volume and weight, but also increases the cost. In a subwoofer, because the power of the subwoofer is relatively large, if the heat dissipation area of ​​the T-iron is small, the speaker will heat up, and long-term use will burn out the circuit in the speaker. Therefore, it is very important to obtain a convex font speaker T-iron that overcomes the above defects. Utility Model Content

[0004] In order to solve at least one of the above technical problems, the utility model provides a convex font speaker T iron, including a cylindrical core shaft, a first end of the cylindrical core shaft radially extending outward with an annular base plate, and a second end of the cylindrical core shaft radially extending outward with a convex ring;

[0005] An arc groove is provided on the lower surface of the annular substrate so that a bulge is formed in the center of the annular substrate, thereby reducing the thickness of the outer circumferential surface of the annular substrate, so that the magnetic conductive circuit is more concentrated, avoiding the magnetic circuit being dispersed at the initial end of the magnetic conductive circuit, increasing the magnetic conductive effect, and reducing the weight of the T iron;

[0006] A through hole is provided at the center of the cylindrical core shaft, the inner wall of the through hole is a convex arc surface protruding inwards, and a step ring is provided on the convex arc surface;

[0007] An annular groove is provided on the first surface of the annular substrate and on the circumference of the cylindrical core shaft, and an annular heat dissipation hole is axially provided on the annular groove and is arranged in an annular manner and passes through the protrusion;

[0008] A plurality of steps are provided on the inner wall of the annular groove.

[0009] Through the above technical solution, the setting of the annular groove can increase the surface of the T-tie of the utility model and play a role in heat dissipation. Furthermore, a plurality of steps are provided on the inner wall of the annular groove, which can reduce consumables and further increase the heat dissipation effect through the stepped annular groove.

[0010] The provision of the annular groove serves to lengthen the length of the cylindrical core shaft, thereby increasing the vibration stroke of the voice coil and improving the power of the speaker.

[0011] Preferably, an outer wall of the cylindrical core shaft between the convex ring and the annular base plate is provided with an arc-shaped recess.

[0012] Through the above technical solution, the arc-shaped concave setting helps to reflect heat and facilitate heat dissipation.

[0013] As a preferred technical solution mentioned above, the outer periphery of the convex ring is located within the width of the annular groove.

[0014] As a preferred technical solution mentioned above, a positioning hole is also provided in the annular groove.

[0015] As a preferred technical solution mentioned above, a radiating heat dissipation groove is provided on the lower surface of the protrusion of the annular substrate. Preferably, the heat dissipation groove is in the shape of a triangular prism.

[0016] Compared with the prior art, the utility model has the following advantages: the utility model has a simple structure, and strip-shaped heat dissipation grooves are added to the lower surface of the annular substrate, so that the heat dissipation effect of the speaker using T iron is good, which is particularly suitable for the high-power requirements of the woofer.
