Problems solved by technology
[0003] The connection and coupling between the sound tube of the BTE and the soft earmold used to be glued during processing to prevent it from slipping out. However, the glue has a certain time limit. After the glue fails, the sound tube is easy to slip out. Especially inconvenient when replacing the sound tube

The invention discloses a sound tube lock for a soft earmold. The lock buckle includes a first cylinder and a second cylinder integrally formed, the diameter of the second cylinder is larger than the diameter of the first cylinder, and a circle of the same diameter is opened in the middle of the first cylinder and the second cylinder hole, the diameter of the first cylinder is 0.6 of the diameter of the second cylinder. The sound tube lock of the soft earmold of the present invention is simple, easy to use, and low in cost, and can prevent the sound tube from loosening or sliding. The first cylinder enters the earmold to increase the friction between the sound tube and the earmold, thereby preventing the sound tube from loosening or sliding. The tube slides, and the second cylinder can only be taken out of the ear mold because the diameter is larger than the first cylinder, so that the sound tube can be easily taken out, and it is also very convenient when replacing the sound tube, and can be reused.
Description
technical field [0001] The invention relates to a sound tube lock for a soft earmold, belonging to the technical field of hearing equipment. Background technique [0002] A hearing aid generally includes a main body and earplugs. The main body includes a microphone for receiving sound from the outside, a speaker for transmitting the sound to the ear, and an electrical device for operating the microphone and the speaker. Earplugs are connected to the main body and inserted into the ears. With regard to earplugs for hearing aids, custom earplugs have recently emerged, that is, earplugs (earmoulds) that are customized to the shape of each user's ear; soft custom earmoulds are usually made by hearing aid fitters, who obtain an impression of a specific ear canal and use the mold. The printed negative molds soft ear molds. The advantage of soft custom earmoulds over hard custom earmoulds is that they provide improved comfort, they reduce sound leakage even compared to hard custo...
