Abstract

The invention relates to a double sound-insulating earplug, comprising a housing, a fixing structure and a sound-absorbing structure, the fixing structure is a conical rubber ring arranged on the outer wall of the housing, and the housing is horizontally arranged with a cavity The cylindrical shell, the shell includes a multi-layer sound insulation board, the sound insulation board is filled with sound insulation cotton, the present invention has chosen to improve the sound insulation structure, using the sound insulation board and sound insulation cotton for double sound insulation, thereby enhancing The sound insulation effect of the earplugs is improved, and at the same time, a new design for the shell and the fixing structure can improve the user experience at the same time, and there will be no pain during the fixing process.

Description

technical field [0001] The invention relates to the field of life, in particular to a double sound-insulating earplug. Background technique [0002] The earliest earplug products originated in Europe, and wax earplugs are the most traditional material. Later, due to the continuous research and development of new materials, a kind of elastic material gradually became the mainstream of making sound-proof earplugs. Earplugs have the function of effectively shielding noise and adapting to noisy environments. The current earplugs have a simple structure, and the noise reduction effect is too small, and the ear canal will be filled and uncomfortable. If it is too loose, it cannot effectively block noise. Contents of the invention [0003] For this reason, the present invention provides a kind of double sound insulation earplug, and the present invention has chosen to improve the sound insulation structure, has used the sound insulation board and the sound insulation cotton to c...
