摘要： The dynamic loudspeaker is comprised of a speaker housing and a front sound panel. A diaphragm is mounted at the front of the speaker. A moving-coil unit is mounted in the speaker and includes a moving coil coupled to the diaphragm for transmitting oscillatory motion thereto. The moving-coil unit when in operation generates heat to such an extent as to tend to limit the rated steady power at which the loudspeaker can be operated without damage to the moving-coil unit. This limiting tendency is counteracted according to the invention by improving the dissipation of the heat generated by the moving-coil unit. The speaker housing or a surface portion thereof and/or the speaker sound panel or sound wall or a surface portion thereof is comprised of a material having a thermal conductivity W equal to or greater than 40 kcal/m-h-.degree. C. A heat-transmitting structure is comprised of a material likewise having a thermal conductivity W equal to or greater than 40 kcal/m-h-.degree. C., and it extends from the moving-coil unit to at least one of the aforementioned portions of the housing and/or sound wall, and is in thermally conductive engagement with both the latter and the moving-coil unit.
