Hearing is a vital function at all stages of life. According to estimates from the World Health Organization (WHO), by 2050 nearly 2.5 billion people will suffer from some degree of hearing loss. At least 700 million of them will require rehabilitation services.This is where the Magnetic Pogo Pin Charging solutions are born.


A hearing aid is a micro-sized sound amplification device. Its purpose is to amplify sound to the level needed by the hearing impaired. In order to help the hearing impaired person to make up for the deficiencies of the hearing impairment, Hearing aids are composed of a number of components, including microphones, amplifiers, receivers, batteries, volume and tone adjustable rotary buttons, and other components. Currently, hearing aids have evolved from the traditional analog type to the computer programmed digital hearing aids. According to their appearance, hearing aids are divided into the following categories: ear-hanging type, invisible ear-hanging type, customized inner-ear type, and pocket type hearing aids.

The issue of recharging hearing aids


In order to ensure that hearing aids remain functional for a long period of time, it is important to keep them fully charged. The majority of hearing aids on the market are powered by replacing the batteries. This means that if the hearing impaired person is away from home for a long period of time, they will need to keep a spare battery. In addition to the majority of hearing aids on the market being dry cell replacements, it is also common to find hearing aids that are USB rechargeable. However, USB docking is inconvenient and the interface can easily get dirty, making it difficult to clean.


Advantages of Pogopin’s magnetic (contact) charging solution


The Magnetic Pogo pin charging solution addresses the aforementioned issues. Primarily, rechargeable hearing aids eliminate the necessity to change batteries, thus significantly simplifying the operational process. This simplification of the operational procedure facilitates the use of hearing aids by elderly individuals, and ensures worry-free use of hearing aids. Secondly, the magnetic contact (Pogopin) charging utilising an in-mould moulding contact pin can be employed to achieve a product that is truly waterproof and dustproof, enabling the device to be used in a variety of scenarios with confidence. Finally, the Magnetic Pogo pin charging method is highly convenient and rapid, with 100% blind suction achievable when the charging male end and female end are in close proximity.


The process of plugging and unplugging is straightforward, and the pogopin has a long service life, with a plugging and unplugging life of more than one million times.


SUNMON primarily engages in research and development of the following products: spring pin connectors, magnetic connectors, non-standard module connectors, special connecting cables, and medical equipment parts and components. In order to meet the demands of the market, we have developed the Pogopin charging solution, which is suitable for use with hearing aids, medical headsets and other products.
