Hearing aid with internal oscillator convenient to replace

Abstract

The invention relates to the technical field of hearing aids, in particular to a hearing aid with an internal oscillator convenient to replace, which comprises a mounting shell specially used for mounting the hearing aid, an electric earplug is fixedly connected outside the mounting shell, and a connector with a slot at the upper end is fixedly connected inside the bottom end of one side of the mounting shell. The connector is electrically connected with the electric earplugs, a mounting groove is formed in the bottom end of the mounting shell, a mounting opening is formed in the side wall of the upper end of the side, away from the mounting groove, of the mounting shell in a penetrating mode, and the heights of a threaded sleeve and a mounting plate are conveniently and rapidly adjusted through a first driving motor, a first gear, a second gear and a screw; the mounting position of the vibrator can be automatically lifted, meanwhile, the vibrator can be stably and rapidly moved from the mounting position in the earphone under the meshing sliding action of a second driving motor, a third gear and a rack plate, the damaged vibrator can be rapidly moved out from the interior in cooperation with a mounting mechanism, and therefore maintenance can be rapidly conducted, the dismounting and mounting time is short, and the working efficiency is high. And the efficiency is higher.
