Referring to fig. 7, the present invention can absorb heat generated during the operation of the earpiece 2 by disposing a plurality of permeable air holes on the earpiece 2, and then by using the heat conduction bag 4 through the air permeable bag 5 and the heat conduction bag 4 distributed up and down, then transferred to the thermal floating ball 6 inside, the thermal floating ball 6 expands after absorbing certain heat, then the buoyancy increases and starts to float upwards, and the air permeable bag 5 at the upper side is extruded to discharge the air accumulated in the air permeable bag 5, so as to realize active air permeability in the air permeable hole, meanwhile, the heat on the hot floating ball 6 is dissipated to the outside by the magnetic heat conduction umbrella 8 and the outer heat conduction sheet 7 to realize cooling, the hot floating ball 6 sinks to reset after recovering the original buoyancy after cooling, the breathable bag 5 can also recover the shape and absorb the outside air to be filled, repeated ventilation actions can be realized by the breathable bag 5, and the breathability of the receiver 2 and the ear is obviously improved.
The above are merely preferred embodiments of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
