Novel in-ear hearing aid

Abstract

The invention discloses a novel in-ear hearing aid which comprises an aid body and a sound transmission system. The novel in-ear hearing aid is characterized in that the aid body and the sound transmission system are in detachable connection. The novel in-ear hearing aid can be completely arranged in ears, has strong shielding effect and maintains the elastic contact with auditory meatus all the time, the front part of the novel in-ear hearing aid can be placed into deep auditory meatus near the eardrum of the human body, the novel in-ear hearing aid is comfortable and stable to wear, and air circulation is good when the novel in-ear hearing aid is worn, people cannot easily sweat while wearing the novel in- ear hearing aid for a long time. the novel in-ear hearing aid can effectively reduce sound feedback and block effect, conduct sound clearly with little gain loss, and is suitable for all patients with slight or serious hearing impairment. Because the novel in-ear hearing aid can be freely bent in the three-dimensional auditory meatus, the novel in-ear hearing aid is suitable for the auditory meatus bending degree of different individuals, can be comfortably placed into or taken out from the auditory meatus and can stably stay in the auditory meatus. Thereby, the manufacture of an ear mark or an ear mold is avoided, and the wearing adaption process and time of the hearing aid can be greatly reduced.

Description

technical field [0001] The present invention generally relates to a flexible hearing device or hearing aid device in general, and more particularly to a new type of in-ear hearing aid that is able to bend comfortably so as to fit each uniquely shaped three-dimensional ear canal of the 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 ...
