Earplug matched with ear in shape

Abstract

The invention discloses an earplug matched with the ear in shape and relates to the technical field of acoustic products in contact with the ear. The earplug matched with the ear in shape comprises an earplug front-cavity shell and an earplug rear-cavity shell, wherein the earplug front-cavity shell and the earplug rear-cavity shell are combined together. A trumpet single body is contained in a space defined by the earplug front-cavity shell and the earplug rear-cavity shell. A sound outlet is formed in the earplug front-cavity shell. An ear coupler covers the outer portion of the earplug front-cavity shell. A through hole used for communicating the sound outlet and the outside environment of the earplug is formed in the ear coupler. The ear coupler is made of foam or soft silica gel or a memory sponge. The earplug matched with the ear in shape solves the technical problems that an in-ear type earplug is not matched with the ear and not comfortable in wearing in the prior art. The shape of the earplug matched with that of the ear can change along with the shape of the ear, so that a user does not feel uncomfortable or painful when the earplug is worn by a user for a long time.

Description

Technical field [0001] The invention relates to the technical field of acoustic products in contact with human ears, in particular to an earplug that matches the shape of the ear. Background technique [0002] The earplugs described in the present invention are earplugs used as personal audio equipment for connecting various audio equipment. The current earplugs can be divided into in-ear type and semi-in-ear type according to the wearing mode. The in-ear earplugs need to be inserted into the ear canal; the semi-in-ear type is placed directly at the outer ear. [0003] The structure of the existing in-ear earplugs all use an independent earplug with an independent silicone sleeve. When using it, you need to put the silicone sleeve on the earplug and then wear it. Earplugs with this structure have the following two shortcomings: [0004] 1. Because the shape of each person's ear is different, and the shape of the mechanized production of earplugs is exactly the same, which cannot ada...

Problems solved by technology

[0004] 1. Because each person's ear shape is different, the shape of the earplugs produced by mechanization is exactly the same, so it cannot adapt to the shape of everyone's ear, causing the wearer to feel severe discomfort or pain when wearing it for a long time ;

[0005] 2. The attached silicone sleeve will become more and more loose with the prolongation of use time and the increase in the number of uses, and it is easy to fall off from the earplugs. If the silicone sleeve is lost, the earplugs cannot be worn or the sound quality of the earplugs will deteriorate sharply.
