referring to fig. 6, a high resilience balloon is placed in the sound-blocking balloon 21, the high resilience balloon includes an outer ventilating spherical shell 61, a positioning inner core 62 located at the center of the outer ventilating spherical shell 61, and a plurality of support rods 63 connected between the inner wall of the outer ventilating spherical shell 61 and the outer surface of the positioning inner core 62, the outer ventilating spherical shell 61 is of a flexible multi-pass through hole structure, so that the inert gas in the sound-blocking balloon 21 can permeate into the high resilience balloon, and the support rods 63 are made of a high-toughness material, in this embodiment, the high resilience balloon can replace the built-in limit ball 212 in embodiment 1, and meanwhile, other structures are consistent with those in embodiment 1, when the sound-blocking hemisphere 211 is accidentally impacted or extruded, after the sound-blocking hemisphere 211 is deformed, the inert gas in the high resilience balloon is extruded to a certain extent, which has a better buffering effect on the deformation of the sound-blocking hemisphere 211 compared with the built-in limit ball 212, and after the impact or extrusion force disappears, part of the inert gas can permeate back into the outer ventilation spherical shell 61 to assist the outer ventilation spherical shell to restore to the original shape under the action that the support rod 63 and the outer ventilation spherical shell 61 restore to shape.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
