Description

Damper with wire clamping structure

Technical Field

The utility model relates to the field of electronic technology, in particular to bullet ripples with card line structure.

Background

A general moving-coil speaker generates sound by using the principle that the reaction force of a fixed magnetic field causes another magnetic field to move in the opposite direction (i.e., opposite poles attract each other and the same poles repel each other). Furthermore, the power alternating current emitted by the power amplifier is transmitted to the voice coil through the lead wire so as to change the polarity of the magnetic field, and the voice coil generates a reaction force relative to the fixed magnetic area generated by the magnetic return device. Positive going impulses cause outward movement of the diaphragm relative to the magnet and negative going impulses cause inward movement of the diaphragm. When the voice coil pushes the diaphragm to reciprocate, the diaphragm pushes air, and the air pressure changes to form sound waves. The damper is responsible for maintaining the correct position of the voice coil in the gap of the magnet core and ensuring that the voice coil reciprocates in the axial direction when subjected to a force.

However, in the prior art, the wires of the speaker are suspended and nothing is available to secure the wires. When the voice coil reciprocates in the axial direction, the wire tends to change position constantly and be pulled along with the reciprocation of the voice coil.
