Description

Hearing aid equipment utilizing near field magnetic communication technology

Technical Field

Background

There are various types of Wireless headsets, and more typically, there are a head set, a neck set, and a Stereo True Wireless (TWS). Hearing aids are also known as The behind-The-ear (bte) type, The In-The-ear (cic) type, and The Receiver In The Canal (RIC) type. For wireless headsets, people select products based on personal preferences, usage scenarios, endurance, price, and other factors. For hearing aids, people pay more attention to factors such as hiding performance, effect, long-term wearing comfort and the like.

With the improvement of living standard and the development of technology, the function, performance and wearability of the hearing aid device are continuously improved and developed. However, at the same time, high performance and multiple functions require more energy and space, which is always contradictory to the pursuit of miniaturization, convenience and beauty, "concealment", and both product design developers and users must make trade-offs and compromises. The most obvious of them is the bluetooth TWS earphone or hearing aid, and the contradiction between the endurance time, volume and more powerful functions of the TWS earphone is prominent, and the hearing aid pursues miniaturization and 'hiding', which limits the adoption of more powerful signal processing systems, more functions and performance improvement.

Therefore, there is a need for a hearing aid device that combines versatility, high performance, and small size.
