Universal hinge in-the-ear hearing aid

Abstract

The present invention discloses a universal hinged in-ear hearing aid, comprising front, middle and rear parts of the hearing aid, the front part of the hearing aid includes a loudspeaker, the rear part of the hearing aid includes a body, and the middle part of the hearing aid includes a sound Conducting device, the sound conducting device is a hinged connection device, one end of the hinged connection device is connected to the front of the hearing aid, and the other end is connected to the rear of the hearing aid, the rotation of the hinged connection device The angle can be controlled freely, and the rotation elevation angle can be as high as 60 degrees, which can meet the requirements of the corner of the human ear canal. The in-ear hearing aid provided by the present invention can be completely placed in the ear, has strong concealment, and always maintains elastic contact with the ear canal, and its front part can be placed in the deep ear canal close to the eardrum of the human body. Air circulation, long-term wearing is not easy to sweat, effectively reduce feedback and occlusion effects, the transmitted sound is clear, and the gain loss is small. It is a universal flexible in-ear hearing aid suitable for any hearing-impaired patients.

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.
