Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, and in particular to a box-type hearing aid. Background Technology

[0002] Hearing aids should be understood as small electronic devices designed to be worn behind or inside the ear of a user with hearing loss. The primary purpose of a hearing aid is to amplify ambient sound sufficiently for the user to perceive. Sound is typically captured by a microphone within the hearing aid, processed electronically by a signal processor, and reproduced by an acoustic transducer. Depending on the user's hearing ability, a professional hearing aid fitter will individually install the amplification device to compensate for the hearing loss by amplifying the frequency range impaired by the hearing loss.

[0003] Traditional box-type hearing aids are bulky, complex in structure, and expensive to use. They are also inconvenient to maintain and have only one microphone. Due to their structural characteristics, this single microphone is easily affected by ambient noise, especially in noisy environments. This increases the workload of the sound processor and causes sound feedback delay. The pickup range of a single microphone is relatively small, usually only able to capture sound within a small area. This means that if the sound source is outside the pickup range, the microphone may not be able to effectively capture the sound, forcing the hearing aid to be used only at close range. While a single microphone may have high sensitivity in some situations, it also makes it equally sensitive to background noise, requiring additional post-processing to reduce noise. This increases the workload of the processor, causing the hearing aid unit to overheat, shortening standby time, and resulting in a poor user experience.

[0004] This invention further optimizes existing box-type hearing aids, developing a box-type hearing aid with a simpler structure, smaller size for easy portability and wearing, better sensitivity, reliable and stable performance, lower cost, convenience and practicality, and a better user experience.
