Abstract: A wireless charging hearing aid is disclosed, comprising a housing, an inner housing, a power management module, a circuit board and a control button. An electromagnetic induction technology is utilized in the disclosed to obtain an inductive current for charging a built-in battery. Elements within the housing do not need to be in contact with an external charging joint, the sealing of the housing is better, thereby achieving complete waterproofing and dustproofing, and improving the adaptability when using the disclosed. Besides, shapes and the number of layers of a receiving coil are flexibly designed according to requirements, and a magnetic conductive sheet is used to shield an inductive magnetic field to prevent the inductive magnetic field negatively influencing other elements. The elements within the housing can be arranged arbitrarily, which improves the flexibility in designing an overall appearance, and facilitates to incorporate artistic designs while reduces the design difficulties.

Abstract: A hearing aid with wireless transmission function is disclosed, comprising a microphone for receiving an ambient sound and outputting it to an audio processing and hearing compensation module; the audio processing and hearing compensation module for processing the sound, amplifying and compressing the sound according to preset hearing compensation parameters, and outputting a processed sound signal to a sound generator (a loudspeaker); and functional control keys for adjusting land controlling various functions, such as adjusting volume, selecting listening program, answering phone, and turning on/off the disclosed.

Abstract: A self-fitting hearing aid having built-in pure tone signal generator is disclosed, comprising a hearing aid and external software. self-fitting is performed to experience a compensation effect through cooperating the compensation form provided by an digital signal processing system with corresponding App fitting software on a computer or mobile phone terminal. Hearing-impaired persons can directly perform self-hearing tests, and the system compiles corresponding parameters, such as frequency, decibel, inflection point and compression ratio according to data of the self-hearing tests, without external devices for various tests. Differences in parameters of the external test devices are avoided through the internal digital signal processing system and the built-in hearing test module in the hearing aid. A speaker inside the same hearing aid is used to the test-fitting and the hearing aid in the disclosed, which simplifies fitting procedures and improves the accuracy of the hearing test and fitting.

Abstract: A hearing aid having tinnitus masking function is disclosed, comprising a hearing aid with a audio signal processing unit and a narrowband noise generator unit. The hearing aid is further provided with a network communication module for network connection between the hearing aid and a control terminal, by means of a wired or wireless manner. By adding a narrowband noise generator mutually independent from the audio signal processing unit, and by using debugging software of a computer terminal or mobile phone terminal to issue instructions to change various parameters of the narrowband noise generator through network transmission, hearing impaired persons who have used the disclosed can improve hearings to promote their communication skills, and corresponding narrowband noises are controlled simultaneously to mask the tinnitus, thereby distracting patients' attentions from the tinnitus, and ensuring that the hearing impaired persons can effectively use the hearing aids to communicate with others.
