Abstract
The utility model relates to an in-ear silencing earplug. The in-ear silencing earplug comprises two parts, namely a rubber body and a core body. The rubber body is soft rubber made of rubber or silica gel and is suitable for closing an external auditory canal of a person. The in-ear silencing earplug is used for blocking and eliminating the vibration generated by a sound source and enters an inner ear through an external auditory canal of the person, and thus the effects of insulating sound and silencing are achieved and the interference to the person caused by noises is eliminated.
Description
Technical field
This utility model is a kind of interference for intercepting, eliminate noise on human, the articles for daily use that audition is kept quite.
Background technology
Current sound pollution is more and more serious, and noise has had a strong impact on people's life, working and learning.
Common people use cotton ball or sponge ball is filled in external auditory canal opening, but erasure effect is also little, only has 30%.The serious factory of some noise can allows the workman put on the sponge earmuff and come noise reduction on the impact of human body, but noise reduction is not good yet, and soundproof effect is less than 30%.The present invention adopts the flexible glue body materials such as rubber or silica gel to make In-Ear Silence earplug, can go deep into and be full of whole external auditory meatus.Volume is few, and is easy to use, can not hinder the activity of user, and erasure effect can reach 80%.
The utility model content
This utility model is the In-Ear Silence earplug that adopts the flexible glue body materials such as rubber or silica gel to make, erasure effect can reach 80%, because flexible glue body material has good damping action to the propagation of sound, the In-Ear Silence earplug made from flexible glue body material, can go deep into and be full of external auditory meatus, the vibration that almost completely hinders the sound source generation is imported internal ear into through external auditory meatus, thereby reaches the purpose of sound-insulation.Because the vibration that sound source produces can be imported internal ear into through skull, pharyngotympanic tube etc., so noise can not be eliminated fully.
This utility model is comprised of colloid and core body two parts, and colloid partly is a kind of flexible glue body that adopts rubber or silica gel to make, and colloid is partly made the cylinder of Radix Dauci Sativae shape, and the colloid size is made the external auditory meatus that is suitable for inserting the people, and colloid surface is made the shallow thread ditch.Core body is made with rigid plastics, and core body inserts the colloid center and is bonded together.Colloid is made with flexible glue body material, and shape is made the cylinder of Radix Dauci Sativae shape, and size is suitable for inserting external auditory meatus, and such colloid can effectively stop up external auditory meatus, intercepts sound and imports internal ear into, reaches the purpose that sound insulation is eliminated the noise.Colloid surface is made the shallow thread ditch, plays scavenging action when colloid is filled in external auditory meatus, is beneficial to colloid and advances external auditory meatus.Core is stopped part and is adopted rigid plastics to make, and inserts colloid center and colloid and is bonded together, and plays the support effect.Because colloid is very soft, is not easy to advance external auditory meatus, institute's heart employing rigid plastics is made core body and is played the support effect.
The beneficial effects of the utility model are, all fill in this Silence earplug when the external auditory meatus of user two ears, and soundproof effect can reach 80%, do not hinder any activity simultaneously.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is In-Ear Silence earplug outside drawing.
Among the figure: 1. colloid, 2. core body, 3. screw thread ditch.
The specific embodiment
When earplug was filled in external auditory meatus, colloid (1) plays sound insulation eliminated the noise, and screw thread ditch (3) forms slit with external auditory meatus and plays scavenging action, can advance the external auditory meatus depths to colloid simultaneously, and when colloid screwed, it is atomic little that slit becomes, and also plays the noise elimination effect.Simultaneously, screw thread ditch (3) has strengthened the pliability of colloid surface, allows user feel more comfortable.Core body (2) plays the support effect to colloid, allows user easily colloid be advanced external auditory meatus.
Claims (2)
1. In-Ear Silence earplug, it is comprised of colloid and core body two parts, it is characterized in that colloid partly is a kind of flexible glue body that adopts rubber or silica gel to make, and core body is made with rigid plastics, and core body inserts the colloid center and also is bonded together.
2. by In-Ear Silence earplug claimed in claim 1, colloid surface is made the shallow thread ditch.
