2results about How to "Reduce inductive reactance" patented technology

The utility model discloses a magnetic circuit assembly, a bone conduction sounding device and a bone conduction earphone. The magnetic circuit assembly comprises a magnetic circuit assembly, a coil and a short circuit piece. The magnetic circuit assembly comprises a magnet and a magnetic conductive plate connected with the magnet, and the magnet is magnetized in the axis direction of the magnetic circuit assembly; the coil surrounds the periphery of the magnetic conductive plate and is used for driving the magnetic circuit assembly to vibrate in the axis direction. And the short-circuit piece is arranged in an alternating magnetic field generated after the coil is electrified, is of a hollow annular structure and is made of a conductive material. According to the magnetic circuit assembly, the bone conduction sounding device and the bone conduction earphone provided by the utility model, the short-circuit piece made of conductive materials is added, and the inductance of the coil is reduced through the short-circuit piece, so that the overall inductive reactance of the magnetic circuit assembly is reduced, and the magnetic performance condition is achieved and improved.

This utility model discloses an electrical cabinet with a low inductive reactance wiring structure, belonging to the technical field of electrical cabinets. It includes a cabinet body with hinged doors at both the front and rear ends. A vertically fixed partition is located inside the cabinet, and a support rod is vertically slidably mounted on one side of the partition near the front end of the cabinet. This utility model, by vertically mounting a partition inside the cabinet and providing doors at both the front and rear ends, along with a sliding support rod on one side of the partition for installing electrical components, and evenly spaced wire slots on the partition, and a wire baffle on the other side to separate and limit the wires, ensures that wiring and electrical component installation within the cabinet are carried out on opposite sides of the partition. Electrical components do not obstruct the straight-line connection of wires, avoiding redundant bending. Wires preferentially follow straight or shortest paths, significantly reducing inductive reactance, improving system stability, and reducing overvoltage, interference, and losses caused by inductive reactance.
