The design of a hearing-aid system involves three disciplines of applied science–electrochemistry, electrical engineering and audio engineering. This paper is concerned with the interface between the first two. Batteries are essentially non-linear components. Optimum performance is only achievable when the electrical requirements of the hearing aid are closely matched with the voltage, rate capability and impedance of the battery. After years of optimalization, the modern ‘675’ button cell has earned universal acceptability and is now used in most ‘behind-the-ear’ hearing aids. When more power is required, the larger and less specialized LR6 ‘penlight’ cell is typically specified. Higher voltage might lead to better circuit efficiency, and there is some pressure to introduce a 3 V lithium-based product. Lithium should give superior energy density, but there are problems which remain to be solved. In the end, it is quite possible that the market might settle for an ecologically acceptable long-life lower voltage metal-air cell. If so, the recent zinc-air system may well have a future and could conceivably succeed both the mercury ‘675’ and the alkaline ‘penlight’ cells.
1. Only a volume adjustment key control hearing aid, the easy operation when you wear;
2. Limited the maximum output, so that the user will not hear the excess volume, which can protect the user’s ear;
3. 3 different earplugs are different people using, it can fit for different sizes ear canal;
4. Mini ITE hearing aid type which can be hidden in the ear and invisible especially for long hair user;
5. Classic appearance with a very cheap price with good market feedback;
6. Factory directly sell with certificates, can be sold all over the world;
7. Design match with ear, comfortable wear, not easy to fall off
1. Noise Reduction and use balanced armature loudspeaker instead of the dynamic loudspeaker;
2. Touch-tone hearing aid, comfortable touching feeling, and easy operation;
3. Beautiful design, small size, and portable with light weight;
4. The rechargeable battery is designed to last for at least 500 recharge cycles. With proper care, the battery can last for up to and beyond 1000 charge cycles;
5. USB charging interface in hearing aid charging base, very convenient for charging;
6. A button operation, the multifunctional button could be a volume control, power switch, and indicator light.
