Problems solved by technology

[0003] Since the shape of the T-iron column is a cylinder with the same thickness, after the T-iron is assembled with the upper splint, it is easy to cause the magnetic gap to be asymmetrical, resulting in uneven magnetic field around the voice coil, and the speaker will be distorted
[0004] For a speaker with a long stroke of the voice coil, the thickness of the mandrel of the T-iron is relatively large. During use, the heat generated by the T-iron is not easy to discharge, which affects the beauty of the speaker's sound, and if the temperature is too high, it will also damage the speaker. cause damage and affect its service life

Abstract

The invention relates to the technical field of loudspeakers, in particular to a double-station-diameter square loudspeaker T-yoke. T-yoke comprising a T-yoke body, a mandrel is arranged at the top ofthe T-yoke body; a cylindrical cavity is formed in the center of the mandrel; the mandrel is further provided with a plurality of positioning grooves. A copper pipe is arranged in cylindrical cavity,outer ridges are arranged on the outer wall of the copper pipe; the outer ridges are embedded into the positioning grooves; inner ridges are arranged on the inner wall of the copper pipe; a lower clamping plate is arranged at the bottom of the T-yoke body, a heat dissipation hole is formed in the center of the lower clamping plate, the lower clamping plate is integrally formed by a circular plateand a square plate, a first limiting ring is arranged on the upper surface of the circular plate, magnetic steel sleeves the periphery of the first limiting ring, an upper clamping plate is arrangedat the top of the magnetic steel, and a cushion block is arranged on the lower surface of the square plate. The copper pipe with the inner and outer double-ridge structure is arranged, the heat dissipation area of the mandrel and the outside is increased, the magnetic steel and the upper clamping plate are positioned through the first limiting ring and the second limiting ring, and it is guaranteed that magnetic gaps between the upper clamping plate and the mandrel are uniform and symmetrical.

Description

Technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a double-diameter square loudspeaker T iron. Background technique [0002] The main function of the T iron in the speaker is to form a magnetic circuit system with the magnetic steel splint. When the magnetic steel is magnetized, a magnetic circuit is formed. When the current passes through the voice coil, the voice coil vibrates back and forth in the magnetic circuit as the current changes, pushing The cone vibrates axially. At present, the traditional magnetic circuit structure is composed of upper splint, magnetic steel, and T iron. T-iron is a key component of the speaker magnetic circuit system. The main function of the T-iron is to conduct magnetism when it is energized. It is limited by the cost of material processing. The prior art T-iron usually consists of a disc-shaped substrate and a column-shaped core. Shaft composition. [0003] Since the shape of the T-iron column...
