Silica gel earplug for back-of-ear hearing aid and use method

Abstract

The invention discloses a silica gel earplug for a back-of-ear hearing aid and a use method, and belongs to the technical field of hearing-aid equipment. The silica gel earplug comprises a main body part, wherein a through channel is formed in an inner cavity of the main body part, one end of the main body part is of a wide-mouth-shaped structure, and sound guide holes are uniformly formed in a sound gathering block; and a lantern ring part, wherein the sound gathering block is embedded in an inner cavity of the lantern ring, and the inner cavity of the lantern ring is provided with an annular cavity surrounding the sound gathering block. According to the invention, the end part of the sounding tube on the hearing aid abuts against the silica gel strip and is pressed inwards along the strip-shaped opening, and the inner cavity of the lantern ring and the interior of the ear canal form a sealing effect, so the sound amplification effect is better, the silica gel earplug is convenient to take out, and instant pain of the ear when a wearer takes out the silica gel earplug is not caused; the dirt blocking structure is arranged to effectively block dirt falling into the ear canal, the problem that the dirt enters the inner cavity of the silica gel earplug and is difficult to clean is avoided, the cleanliness of the interior of the silica gel earplug is improved, and then the wearing comfort of a user is improved.

Description

technical field [0001] The invention relates to the technical field of hearing aid equipment, in particular to a silicone earplug for a behind-the-ear hearing aid and a method for using it. Background technique [0002] A hearing aid is a small loudspeaker that amplifies the originally inaudible sound, and then uses the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain so that the sound can be felt. Sound is produced by the vibration of objects, and the sounding object is called the sound source. Sound is just the movement of pressure waves through the air. Pressure waves vibrate the small bones in the inner ear, and these vibrations are translated into tiny electrical brain waves, which we perceive as sound. The inner ear works on the same principle that a microphone captures sound waves or a speaker pronounces, it's the relationship between moving mechanical parts and air pressure waves. Naturally, when the sound waves are lo...

AI Technical Summary

Problems solved by technology

[0003] The silicone earplugs on the hearing aid are prone to insufficient sealing when worn, causing the sound to radiate outwards, reducing the sound amplification effect, and when taken out, it is easy to cause instant pain inside the ear canal, which brings bad results to the user. The feeling of experience reduces the comfort when wearing, and the dirt falling from the ear canal easily enters the inner cavity of the silicone earplugs. There are many grooves in the silicone earplugs, which makes it difficult to clean up later, making the cleanliness of the silicone earplugs unacceptable. To ensure that, for this reason, we propose a silicone earplug for behind-the-ear hearing aids and its usage method
