Abstract

The invention provides a simple noise reduction earplug. The simple noise reduction earplug comprises a left connecting line, a right connecting line and two noise reduction earplugs, wherein two noise reduction earplugs are respectively arranged at one end of the left connecting line and one end of the right connecting line; the other end of the left connecting line and the other end of the rightconnecting line are electrically connected with a metal plug; each of the left connecting wire and the right connecting wire comprises a wire fixing pipe and a plurality of connecting wires; the outer surface of one part of the plurality of connecting wires are wrapped with a first braided layer; the outer surface of the other part of the plurality of connecting wires are wrapped with a second braided layer; the outer surface of each first braided layer and the outer surface of each second braided layer are wrapped with a third braided layer; one end, connected with a noise reduction earplug,of each third braided layer is hooped through a metal fixing piece; the plurality of connecting wires penetrate out of each third braided layer to be electrically connected with a loudspeaker; each wire fixing pipe comprises a metal head and a connecting ring; and one end, connected with a noise reduction earplug, of each third braided layer is sleeved by a connecting ring.

Description

technical field [0001] The invention belongs to the technical field of in-ear earplugs, and in particular relates to a simple noise reduction earplug. Background technique [0002] Industrial noise refers to the noise generated during the operation of mechanical equipment. According to the characteristics of the noise source, it can be divided into: airflow noise, mechanical noise and electromagnetic noise, which can easily affect the rest and work of workers in the factory. Working under strong noise for a long time will cause Hearing fatigue and hearing loss. If you are exposed to strong noise for many years, organic lesions will occur in the ear organs, and noise-induced deafness will appear. This results in noise-proof earplugs. Noise-proof earplugs are generally made of silicone, low-pressure foam, or high-elastic polyester materials. After being inserted into the ear canal, they are in close contact with the external auditory canal to prevent sound from entering the mi...
