Non-separable deformable ear hook of intra-aural receiving behind-the-ear BTE

Abstract

The invention discloses a non-separable deformable ear hook of an intra-aural receiving behind-the-ear BTE. The BTE comprises a machine body and an intra-aural receiving or sound conducting device for receiving and outputting sound, which is put in an auricula and extends into an external auditory canal; the machine body and the sound conducting device are connected through the ear hook. The ear hook and the machine body of the BTE are connected and are non-removable; furthermore, the ear hook can be used on both left and right ears; the shape and the size of the ear hook can be changed, so that the ear hook is applied to auriculas of different patients; the ear hook is unnecessary to be pre-made into fixed curved shape and size in factories; but, the ear hook is convenient for BTE fitting people to curve and stretch by hands in shops or at home by patients; furthermore, the ear hook is made of a material and a structure for self-keeping curved deformation; the sound conducting device comprises a loudspeaker component and an ear mould; the ear mould comprises a fixed tube and a mould head connected with the loudspeaker component, wherein the size of the fixed tube is constant; the mould head is made of a soft material and is different in size. By means of the manner, the non-separable deformable ear hook disclosed by the invention is self-adaptive to auriculas and facial structural shapes and is applied to being worn by different crowds in different stages; furthermore, the non-separable deformable ear hook is easy to carry.

Description

technical field [0001] The invention relates to the field of hearing aids, in particular to a non-detachable deformable earhook of a BTE hearing aid, which is non-detachable, stretchable and bendable. Background technique [0002] Most of the hearing aids in the existing hearing aid market are behind-the-ear hearing aids BTE and deep ear canal hearing aids CIC. However, the behind-the-ear hearing aid BTE cannot make full use of the acoustic advantages of the human ear's helix, auricle, and ear canal's sound wave amplification, stereophonic sound, and directionality because the microphone is placed behind the ear; while the deep ear canal hearing aid CIC is limited to the inside of the ear canal The small space cannot meet the needs of high power or large batteries, and the complex physiological structure of the ear canal cannot maintain the sound pressure well, resulting in howling and acoustic feedback, as well as the discomfort caused by wearing occlusion.

Problems solved by technology

To equip one ear with a hearing aid, it is often necessary to prepare a total of six ear hooks in three sizes for the left and right ears, which is very inconvenient and wasteful, and given the limited range of changes in the three sizes, it cannot meet the needs of various ears and facial shapes of men, women, and children. actual size needs
