Abstract
A horn voice coil heat dissipating structure essentially comprises a first footstep, a second footstep and an external footstep. The first footstep is round cover shape, the surface of which is equipped with an opening hole and the bottom edge of which is equipped with a projecting wall which extends outwards horizontally. The second footstep is round cylinder shape, the upper opening edge of which is equipped with a projecting wall that extends outwards horizontally. The external footstep is hollow reversed cone shape. The second footstep is covered on the horn voice coil after being covered on the first footstep. Then, the external footstep is covered on the first footstep. The bottom edge of the external footstep and the one end of the elastic wave of the horn are fixed on the projecting wall of the first footstep, and the upper edge of the external footstep is fixed on a drum paper. When the horn is used, the high temperature generated from the horn voice coil is dissipated through the first footstep and the second footstep to avoid the looseness of the voice coil of the horn and the drum paper of the horn caused by the high temperature.
