Problems solved by technology

At present, PCs are mainly used to connect hearing aids, and the electroacoustic indicators of hearing aids can be changed by adjusting the parameters of the integrated circuit amplifier of the digital signal processing chip. This can be called software adjustment, and there are still some shortcomings in the use of some specific groups of people.
In addition, after some hearing-impaired patients wear hearing aids, they will also have an ear blocking effect.

Abstract

The invention relates to a hearing aid with a physical sound conductive module. The hearing aid comprises the sound conductive module used for transmitting sound signals to an ear canal. The sound conductive module comprises one or more sound conductive units which are stacked sequentially. Each sound conductive unit comprises an ear mold supporting board and a sound conductive tube installed on the ear mold supporting board. The sound conductive tube of each sound conductive unit is circled on the corresponding ear mold supporting board so as to be of a bent spiral shape. A sound inlet and a sound outlet of the sound conductive tube of each sound conductive unit are formed in the front side face and the rear side face of the corresponding ear mold supporting board respectively. The sound outlet of the sound conductive tube of each former sound conductive unit is in butt joint with the sound inlet of the rear adjacent sound conductive unit. The sound inlet of the sound conductive tube of the sound conductive unit on the side close to a panel is connected with a telephone receiver. The sound outlet of the sound conductive tube of the sound conductive unit on the side away from the panel extends to an ear canal outlet of a customized shell. The intermediate-frequency gain frequency response of the hearing aid can be enhanced, meanwhile, high-frequency noise is lowered, sound feedback of the hearing aid is reduced, and sound articulation is improved.

Description

technical field [0001] The invention relates to a hearing aid, in particular to a hearing aid with a physical sound guide module, which belongs to the field of medical equipment. Background technique [0002] In-ear hearing aids are currently the most widely used customized hearing aids. This kind of hearing aid needs to be customized according to the ear canal model of different patients. The main external structure is a customized shell and panel, and the internal structure is composed of microphones, digital signal processing chips This is a common product structure in the world. The advantage is that it is relatively simple and easy to produce. The disadvantage is that the characteristics of the sound change slightly in physical conditions. At present, PCs are mainly used to connect hearing aids, and the electroacoustic indicators of hearing aids are changed by adjusting the parameters of the integrated circuit amplifier of the digital signal processing chip. This can be...
