AI Technical Summary

Technical Problem

Existing behind-the-ear hearing aids are prone to falling out during users' daily activities due to dynamic changes and reduced ear friction, resulting in poor fixation and affecting wearing comfort and stability.

Method used

It adopts a multi-directional adjustable behind-the-ear hearing aid fixing mechanism. Through mechanical transmission and locking structure, the sliding frame is pulled by the data cable, which drives the sliding rod and the drive shaft to slide, realizing the real-time adjustment of the locking frame, providing continuous fixing force, and resisting the influence of external factors.

Benefits of technology

It significantly improves the fixation reliability and wearing comfort of hearing aids, avoids them falling out due to ear muscle movement or reduced friction, and enhances the stability of the fixation mechanism.

Abstract

The utility model provides a multidirectional adjustable back-of-ear hearing aid fixing mechanism, which relates to the technical field of hearing aids and comprises a hearing aid body, a hanging neck fixedly connected onto the hearing aid body and a clamping structure, the clamping structure comprises a rotating block slidably connected onto the hanging neck, an outer sliding rod is fixedly connected onto the rotating block, and an inner sliding rod is fixedly connected onto the outer sliding rod. A transmission block is fixedly connected to the outer sliding rod, a transmission shaft is connected to the transmission block in a sliding mode, a sliding rod is fixedly connected to the transmission shaft, a sliding frame is fixedly connected to the sliding rod, the sliding frame is connected to the hanging neck in a sliding mode, and a lower sliding frame is fixedly connected to the rotating block. Even if the friction force is reduced due to sweating or grease secretion of the ears of the user, continuous fixing force can still be provided based on mechanical transmission and clamping triggered by pulling of the data line, the reliability and wearing comfort of the fixing mechanism are remarkably improved, and the problem that in the prior art, a fixing mechanism is prone to falling off is effectively solved.
