Embodiment Construction

[0020] Such as figure 1 As shown, a hearing aid earplug includes an earplug main body 1 and a sound channel 3 on the earplug main body 1, the earplug main body 1 is composed of a support piece 2, and the support piece 2 is mushroom-shaped; as figure 2 As shown, an air channel 4 is provided between the earplug main body 1 and the sound channel 3 , and the air channel 4 is non-linear and circuitous along the length direction of the ear canal.

[0021] In order to focus and reflect the sound waves back to the eardrum, the front end of the supporting sheet 2 is a smooth convex surface, so that the sound waves will not be diffracted and diverged. The surface of the support sheet 2 can be surface treated, such as coating, coating, etc., ETFE, PTFE, Parylene, Parylin, Parylast, Polyurethane, Polyethylenemin, Polyimide and the like.

[0022] In order to absorb or diffract the sound waves outside the ear, the rear end of the supporting sheet 2 is a rough concave surface, so that the ...

Abstract

The present invention discloses a pair of hearing-aid ear-plugs. The ear-plugs comprise ear-plug main bodies (1) and sound channels (3) on the ear-plug main bodies (1). The ear-plug main bodies (1) consist of support sheets (2). Air channels (4) are arranged between the ear-plug main bodies (1) and the sound channels (3). The air channels (4) are non-linear circuitous type air channels arranged along the long direction of ear canals, and the aperture of the air channel (4) is more than 0.5mm. The ear-plug structure effectively avoids sound pressure leakage and avoids eardrum damage due to excessive stuffing. Sound pressure leakage or absorption is reduced by the surface design of the ear-plugs to the utmost extent. The design of the circuitous type air channels (4) eliminates blocking effect, reduces excessive leakage of horn sound waves or sound pressure, and prevents excessive sound waves outside ears from entering inner ears. Besides, the present invention can avoid loosening or displacement and avoid receiver vibration and resonance. The ear-plugs are soft, comfortable to wear, convenient to exchange or clean, and easy to put and take out.

Description

technical field [0001] The invention relates to an earplug of a hearing aid and belongs to the technical field of hearing aids. Background technique [0002] In the technical field of hearing aids, commonly used hearing aid earplugs generally have a certain shape and are made of silicone rubber. For example, a part of earplugs in the well-known European Union (EU) Design No. 000007893-0001 registered on April 1, 2003. Such earplugs often encounter the following situations during use: the sound pressure leaks due to the length, size and shape of the user's ear canal; the use causes the air near the center of the ear canal to fail to circulate; the material is too soft to cause loosening Or fall off, the material is too hard to damage the ear canal and so on. Preventing sound pressure leakage along the periphery of the earplugs, preventing the occlusion effect of air circulation near the center of the ear canal, preventing earplugs from loosening or falling off, preventing v...
