Description

technical field [0001] The invention relates to a hearing aid device, in particular to a general-purpose in-ear hearing aid, which can freely adjust the three-dimensional bending angle and length of the in-ear hearing aid device in the auditory canal of a human body. Background technique [0002] At present, manufacturers of digital hearing aids generally focus on increasing the power of hearing aids to obtain larger audio output signals or gain, suppress environmental noise, and eliminate sound feedback signals to ensure the quality of output signals. The consequence is that even if the quality of the output signal is very good, the gain effectively received by the user is very little, and the user cannot obtain a good hearing aid effect. Because custom-made hearing aids are generally placed on the auricle, and behind-the-ear hearing aids are placed behind the ear, the sound from the speaker is still a considerable distance away from the human eardrum. The loss of the cond...
