a hearing aid comprises a shell, a gear assembly, a movable rack and a limit button; a moving groove is formed in one side, close to the auricle, of the shell; the movable rack is movably arranged in the movable groove; a gear assembly is arranged in the shell and comprises a driven gear and a driving gear; the driven gear is respectively meshed with the moving rack and a driving gear, and the driving gear protrudes out of the surface of the shell; the driving gear is shifted to drive the driven gear, so that the movable rack can do left-right linear motion; the shell is also internally provided with the limit button which is used for limiting the rotation of the driven gear.
As a preferred scheme of the utility model, an earphone body is arranged at one end of the movable rack; the earphone body is sleeved with an earplug, the earplug is of a hollow structure, and a dustproof film and a waterproof film are sequentially arranged in the earplug.
As an optimized proposal of the utility model, a sound receiving unit, an audio amplification unit, a signal processing unit and a battery are arranged in the shell.
As a preferred proposal of the utility model, a massage lug is arranged on one side of the shell body close to the auricle.
As a preferred scheme of the utility model, be provided with the auricle groove on the casing.
As a preferred embodiment of the present invention, the earplug is made of a high-elasticity polyester material.
To sum up, the utility model discloses following beneficial effect has: the utility model discloses an adopt and remove the rack, make the earplug not only confine to place at user's duct edge, can also adjust the earplug, stretch into the duct, improved user's hearing aid effect. The outer ear grooves are formed in the shell, so that the stability of the hearing aid is improved. Because the earplug is made of the high-elasticity polyester material, discomfort of a user can not be caused by the sizes of the inner ear canal and the outer ear canal when the earplug is movably adjusted, and the comfort of the user is improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Examples
As shown in fig. 1, the present invention relates to a hearing aid comprising a housing 2, a gear assembly, a moving rack 16 and a limit button 5.
Specifically, a moving groove 6 is arranged on one side of the housing 2 close to the auricle, a moving rack 16 is movably installed in the moving groove 6, and the moving rack 16 makes a horizontal linear motion. The earphone body 12 is arranged at one end of the movable rack 16, the earplugs 13 are sleeved on the earphone body 12, the earplugs 13 are of a hollow structure, wherein the earplugs 13 are made of high-elasticity polyester materials, and the comfort of a user is improved. A dust membrane 11 and a water-proof membrane 10 are arranged in the earplug 13 in order to prevent dust or water from entering the hearing aid and damaging it. Within the housing 2 is mounted a gear assembly comprising a driven gear 4 and a drive gear 3. The driven gear 4 is engaged with the moving rack 16 and the driving gear 3, respectively, and the driving gear 3 protrudes from the surface of the housing 2. The driving gear 3 is shifted to drive the driven gear 4, so that the moving rack can do left-right linear motion.
