TECHNICAL FIELD
[0001] The utility model relates to the technical field of hearing aid, especially relates to an in-ear hearing aid. BACKGROUND
[0002] The in-ear hearing aid is also called the concha hearing aid. The in-ear hearing aid is the earliest developed and applied custom hearing aid. It occupies the concha and the cymba concha, and is also called the concha hearing aid in terms of anatomy. The shell is customized according to the shape of the concha of the hearing-impaired person, the microphone, the amplifier and the earphone are all placed in the customized shell, and no wire and hose are needed outside, so that the in-ear hearing aid can be completely placed in the cymba concha, the concha and the external auditory canal, and is relatively concealed and light. The microphone inlet of the in-ear hearing aid is located on the outer side of the hearing aid, which is more in line with the natural position of the human ear to perceive sound than the behind-the-ear hearing aid. The in-ear hearing aid has a relatively large volume and panel area, so that the double-microphone technology is relatively easy to apply.
[0003] The in-ear hearing aid has a filter screen on one side of the sound pickup hole, and the filter screen is arranged on the inner side of the in-ear hearing aid shell. The filter screen is usually called a wire mesh protection, and its main function is to protect the sound pickup hole of the hearing aid from interference by foreign matter in the external environment, and also helps to reduce the influence of external noise on the hearing aid, so as to ensure that the hearing aid can more accurately capture sound signals. However, when foreign matter enters the inner side of the filter screen through the sound pickup hole, it cannot be cleaned through the sound pickup hole due to the small diameter of the sound pickup hole. If the foreign matter in the inner side of the filter screen needs to be cleaned, the shell of the in-ear hearing aid needs to be opened, thereby increasing the difficulty and speed of cleaning the filter screen, and non-professionals are also likely to cause damage to the electronic components in the shell when disassembling the shell. Therefore, the in-ear hearing aid is proposed to solve the above problems. SUMMARY
