A yoke for the speaker includes: a parent member molded of an iron-based powder; and a heterogeneous material molded of a metal powder having a higher conductivity and a lower magnetic susceptibility than the iron-based powder, wherein the heterogeneous material is integrally disposed on at least one of a part of a surface of the parent member, or an internal portion of the parent member, or both, and the heterogeneous material diverts an eddy current generated in the parent member.

Yoke for speaker having heterogeneous material and iron-based material integrally molded, method of manufacturing the same, and speaker apparatus including yoke for speaker

The electric wire is a heat pipe type of electric wire and includes a wick part having a channel in an internal space in which a refrigerant in a gas state with a phase changed by heat flows, and passing the refrigerant in a liquid state with the phase changed by heat using a capillary phenomenon. A conductive part surrounds and seals the wick part and is made of a conductive material and an insulating cover insulates the conductive part from the outside by surrounding the conductive part. The insulating cover has one or more via holes exposing the conductive part to the outside.
