Abstract

The present invention relates to the technical field of medical instruments, and particularly relates to an elastic adjustment structure of an ear-hook hearing aid. A reel penetrates a reel through hole. A compressed spring sheaths on a line press shaft. The other end of an enameled flexible cable enters through an upper end of a line hole, then penetrates a through hole of the line press shaft, then extends into an opening slot and is fixedly connected with the reel finally. A hearing aid body is disposed on a back surface of a support seat. When the elastic adjustment structure is used, the line hole and the through hole of the line press shaft are in a coaxial state by pushing the line press shaft, the enameled flexible cable is tightened or loosened, so as to make an ear comfortable; and the compressed spring rebounds after a push force is eliminated, so that the line press shaft tightly presses the enameled flexible cable on a hole wall of the line hole so as to locate and wind the enameled flexible cable on the reel. The elastic adjustment structure is simple and convenient to adjust, is difficult to release, is applicable to people of different ages, and brings great convenience to patients. The elastic adjustment structure has the advantages of simple structure, reasonable arrangement, and low manufacture costs.

Description

technical field [0001] The invention relates to the technical field of the medical equipment industry, in particular to an elastic-tight adjustment structure of an ear-hook hearing aid. 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. Ear-hook hearing aids are the most widely used type. It is inconvenient to take off and put on ear-hook hearing aids, and people of different ages and sizes have different ear sizes, so generally ear-hook hearing aids need to be customized The size, and it cannot be easily replaced after it is customized, which brings great inconvenience to the patients who wear it. [0003] Therefore, it is necessary to carry out further technical innovation to the structure of the existing ear-hook hearing aid. Contents of the invention [0004] The ...
