Description
Technical Field
The present utility model relates to hearing aid devices, and in particular to a hearing aid with replaceable earplugs.
Background
A hearing aid is a device that helps hearing impaired persons to improve hearing by receiving, amplifying and adjusting sound to fit the hearing situation of the user. Among these, earplugs are an important component of hearing aids that connect the hearing aid body to the user's ear canal while conducting amplified sound from the hearing aid body into the user's ear canal.
Existing hearing aids typically employ a fixed earplug design, meaning that the size and shape of the earplug is fixed and cannot be adjusted to the size and shape of the user's ear canal. Thus, such an integrated design may cause discomfort to some users during use or affect the sound conducting effect of the hearing aid due to insufficient matching of the earplug to the ear canal. Furthermore, the fixed earplug design also means that the earplug cannot be easily replaced, which can be inconvenient when the earplug is damaged or requires cleaning.
In addition, the existing connection design of the earplug and the hearing aid body often adopts a fixed connection mode, and the mode is simple, but when the earplug needs to be replaced, the hearing aid body needs to be disassembled, so that the steps are complex, and damage to the hearing aid body is also possible.
Accordingly, there is a need to develop a new type of hearing aid with replaceable earplugs to provide a better user experience, to improve hearing aid results, and to simplify maintenance and replacement procedures for the hearing aid.
Disclosure of Invention
The utility model provides a hearing aid with a replaceable earplug, comprising a hearing aid body and a replaceable earplug connected thereto. The hearing aid body contains electronic components for receiving, processing and amplifying sound inside, while the hearing aid body provides an earplug connection interface for connection with an earplug.
The earplug includes an earplug body, a sound channel and a connection portion. The earplug body is shaped and sized to comfortably fit the ear canal of most users. Further, the earplug is configured with a slightly larger version and a slightly smaller version. The sound channel is provided inside the earplug body for conducting sound from the hearing aid body to the ear canal of the user. The connecting portion is arranged at one end of the earplug body and is used for being connected with an earplug connecting interface of the hearing aid body.
The connecting part and the earplug connecting interface of the hearing aid main body are designed to be mutually matched, so that the earplug can be easily connected with and disconnected from the hearing aid main body. Specifically, the outer circumference of the connecting part is provided with external threads, the inner circumference of the earplug connecting interface is provided with an internal thread receiving part matched with the external threads, and a user can easily install and replace the earplug in a spiral installation mode.
6. In order to prevent the earplug from being separated in the using process, the utility model also designs a limiting device. The limiting device is sleeved on the rubber limiting ring on the outer side face of the earplug connecting interface of the hearing aid main body, the inner side face of the rubber limiting ring is tightly sleeved on the outer side face of the earplug connecting interface, the upper end of the rubber limiting ring is higher than the earplug connecting interface by 4-6mm, an inner convex ring is arranged on the inner side of the middle of the higher portion, a groove matched with the inner convex ring is formed in the root of the connecting portion of the earplug, when the earplug is connected with the hearing aid main body, the inner convex ring on the rubber limiting ring can be clamped into the groove in the screwing process, meanwhile, the upper end face of the rubber limiting ring also props against the earplug, so that the earplug is prevented from being excessively screwed between the earplug and the hearing aid main body, and the earplug can be firmly fixed on the hearing aid. The thickness of the inner convex ring is 1-2mm.4. The section of the inner convex ring is trapezoid. The clamping in and the screwing out are convenient.
Furthermore, the material of the earplug main body is soft, comfortable and durable medical grade silica gel, so that better wearing experience is provided, and meanwhile, the material has good ageing resistance and pollution resistance, and can be kept clean and comfortable for a long time.
The hearing aid adopts the replaceable earplug design, so that a user can easily replace earplugs with different sizes or types according to own requirements, and the use flexibility and the comfort level of the user of the hearing aid are greatly improved. Through setting up rubber spacing ring and groove structure, realized in the screw in process, the interior bulge loop on the rubber spacing ring can block into the recess, effectively prevent to break away from between audiphone and the earplug in the use, can prevent simultaneously excessively to screw, ensure that the earplug can firm reliable fix on the audiphone. By adopting the spiral installation mode, a user can easily install and replace the earplug without professional technician operation, thereby greatly improving the use convenience of the hearing aid.
Therefore, the hearing aid has remarkable advantages in the aspects of improving the use experience of users, improving the durability of products, facilitating installation and replacement and the like, and has good practical value.

Detailed Description
The technical scheme of the utility model is further explained below with reference to the accompanying drawings.
The utility model provides a hearing aid with a replaceable earplug, comprising a hearing aid body 1 and a replaceable earplug 2 connected thereto. The hearing aid body 1 contains electronic components for receiving, processing and amplifying sound inside, while the hearing aid body provides an earpiece connection interface 4 for connection with an earpiece.
The earplug comprises an earplug body, a sound channel and a connecting part 3. The earplug 2 is shaped and sized to comfortably fit the ear canal of most users. Further, the earplug is configured with a slightly larger version and a slightly smaller version. The sound channel is provided inside the earplug body for conducting sound from the hearing aid body to the ear canal of the user. The connecting part 3 is arranged at one end of the earplug body and is used for being connected with the earplug connecting interface 4 of the hearing aid body 1.
