AI Technical Summary

Technical Problem

Existing hearing aids suffer from significant foreign body sensation and limited portability. In-ear hearing aids cause a foreign body sensation when inserted into the ear canal, while bone conduction hearing aids cause pressure on the head and are not portable.

Method used

A portable hearing aid has been designed with a curved shell for the grip and a lanyard hole. The microphone and speaker are connected to the control circuit board. The shell contains a volume control switch, an LED indicator, and a charging port. The ear pad and connector structure simplifies the wearing method and avoids putting pressure on the ear canal or head.

Benefits of technology

It improves ease of use and versatility, reduces hand fatigue, avoids foreign body sensation and pressure, is easy to carry and not easily lost, and is suitable for users with hearing loss in the left or right ear.

Abstract

This utility model discloses a portable hearing aid, including a shell, a microphone, a speaker, and a control circuit board. The microphone and speaker are electrically connected to the control circuit board. The microphone is used to receive external sound signals and transmit the sound signals to the control circuit board. The control circuit board is used to receive the sound signals transmitted by the microphone, process the sound signals, generate processed audio signals, and transmit the audio signals to the speaker. The speaker is used to receive the audio signals transmitted by the control circuit board and convert the audio signals into sound output. The shell has a grip with an arc shape. The arc design can closely fit the natural curve of the user's palm, improving the comfort of holding the device. The shell is provided with a lanyard hole, allowing the user to hang the hearing aid around their neck with a lanyard for easy carrying and to prevent loss. When the hearing aid needs to be used, the user can hold the hearing aid close to their ear using the grip. When not in use, the user can hang it around their neck with the lanyard.
