silent noise canceling earplugs

Abstract

The invention relates to a silent noise reduction earplug. The silent noise reduction earplug includes a soft and elastic plug sleeve and a soothing device placed inside the plug sleeve; the soothing device includes a central control tube, which is provided with a Central controller, the central controller divides the central control cylinder into two sections of space that are not connected to the left and right; the two ends of the central control cylinder are respectively connected with a diversion tube, and the free end of the diversion tube is closed; inside the plug sleeve Filled with elastic and closed soothing balls, the inside of the soothing ball is hollow, and each soothing ball is connected to the guide tube through the guide tube; The soothing balls on the earplugs are distributed in a staggered way in the plug sleeve; the central control tube, the guide tube and the soothing ball are filled with soothing liquid; The stimulation of the ear canal skin and capillaries improves the comfort of the ear and provides users with a comfortable and quiet space for meditation.

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
