Silence noise reduction earplug

Abstract

The invention relates to a silence noise reduction earplug which comprises a soft elastic plug sleeve and a relieving device arranged in the plug sleeve. The relieving device comprises a center control cylinder, a center controller, the center control cylinder is divided into two spaces which are not bilaterally communicated, flow guide pipes are communicated with two ends of the center control cylinder, free ends of the flow guide pipes are closed, the inside of the plug sleeve is filled with elastic, closed and hollow relieving balls, the relieving balls are communicated on the flow guide pipes guiding tubes, the relieving ball on the flow guide pipe of one end of the center control cylinder and the relieving ball of the flow guide pipe of the other end of the center control cylinder aredistributed in a staggered manner in the plug sleeve, and the center control cylinder, the flow guide pipes and the relieving balls are filled with relieving liquid. The silence noise reduction earplug is novel in structure and unique in principle, noise reduction effect is ensured, stimulation to ear cannel skins and capillary is effectively relieved, comfort of ears is improved, and comfortableand quiet meditation space is provided for a user.

Description

technical field [0001] The invention relates to a noise reduction earplug, in particular to a passive noise reduction earplug. Background technique [0002] With the acceleration of the pace of life, people in the city are busy with work and entertainment all day long, and it is becoming more and more difficult to set aside time for solitude, thinking or quiet reading. The hustle and bustle of the city can easily interrupt fleeting thoughts and It is easy to make people feel irritable; so noise reduction products have emerged as the times require, from noise reducers, noise reduction headphones to noise reduction earplugs, there are many types, but in terms of their noise reduction principles, they can be roughly divided into two types of products: one The first is an active noise reduction product, which collects and analyzes the sound waves of the external environment sound, and uses the feedback microphone to emit the anti-phase sound wave of the environmental sound, ther...

[0002] With the acceleration of the pace of life, people in the city are busy with work and entertainment all day long, and it is becoming more and more difficult to set aside time for solitude, thinking or quiet reading. The hustle and bustle of the city can easily interrupt fleeting thoughts and It is easy to make people feel irritable; so noise reduction products have emerged as the times require, from noise reducers, noise reduction headphones to noise reduction earplugs, there are many types, but in terms of their noise reduction principles, they can be roughly divided into two types of products: one The first is an active noise reduction product, which collects and analyzes the sound waves of the external environment sound, and uses the feedback microphone to emit the anti-phase sound wave of the environmental sound, thereby canceling the environmental sound, and then achieving noise reduction; because collection, analysis, and feedback require certain processing Time, so active noise reduction products cannot eliminate sudden and irregular noise; the other is passive noise reduction products, which achieve noise reduction by blocking the sound transmission path. Common products such as earplugs block the noise through earplugs. The ear canal isolates the eardrum from the outside air, so that external sounds cannot be transmitted from the air to the human ear, thereby achieving passive noise reduction; therefore, the sealing between the product and the human ear seriously affects the effect of passive noise reduction, and many products blindly The pursuit of sealing makes the earplugs exert greater pressure on the human ear, oppresses the capillaries in the ear canal, and hinders blood circulation; long-term wearing will cause ear discomfort and even damage the ear canal
