A general-purpose hinged in-ear hearing aid

Abstract

The invention discloses a universal hinge in-the-ear hearing aid, which comprises a front part, a middle part and a back part of the hearing aid, wherein the front part of the hearing aid comprises a loudspeaker; the back part of the hearing aid comprises a machine body; the middle part of the hearing aid comprises a sound conduction device; the sound conduction device is a hinge connection device; one end of the hinge connection device is connected with the front part of the hearing aid and the other end of the hinge connection device is connected with the back part of the hearing aid; the rotation angle of the hinge connection device can be freely controlled; and the rotation elevation angle is up to 60 degrees, so the requirement of the human auditory meatus corner is met. The in-the-ear hearing aid provided by the invention can be completely placed in the ear, has strong stealthiness and keeps elastic contact with the auditory meatus; the front part of the hearing aid can be placed in the deep auditory meatus close to the human eardrum; the in-the-ear hearing aid is comfortably and steadily worn; when the hearing aid is worn, the air in the ear is ventilated so that the wearer is not easy to sweat after wearing for a long term; the universal hinge in-the-ear hearing aid can effectively reduce feedback and occlusion effects; the conducted sound is clear; the gain loss is reduced; therefore, the universal hinge in-the-ear hearing aid is flexible and suitable for all patients suffering from hearing impairment.

Description

technical field [0001] The invention relates to a hearing aid device, in particular to a general-purpose hinged in-the-ear hearing aid, which can freely adjust the three-dimensional bending angle of the in-the-ear hearing aid device in the human ear canal, and the rotation elevation angle is as high as 60 degrees, which can adapt to the corner of the human ear canal requirements. 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...

Problems solved by technology

[0012] In view of the above-mentioned product defects that cannot meet the needs of the market, the purpose of the present invention is to provide a general-purpose hinged in-ear hearing aid, which has the advantages of both the in-the-ear hearing aid and the general-purpose in-the-ear hearing aid. The rotation elevation angle of the knot is as high as 60 degrees, which can meet the requirements of the corner of the human ear canal. It is easy to place in the deep ear canal very close to the human eardrum. It is comfortable and stable to wear, and the air in the ear circulates when worn, and it is not easy to sweat when worn for a long time. Eliminate the occlusion effect and feedback howling, the transmitted sound is clear, and the gain loss is small. It is a general-purpose rigid in-ear hearing aid suitable for any patient.
