Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The behind-the-ear bone conduction hearing aids of the embodiments of the present invention may be bone conduction hearing aids or bone conduction earphones, which mainly include components such as a casing, a sound transmission component, and a circuit component, and of course also include a sound pickup component or a bluetooth parts etc.

According to the specific product form of the present invention, the sound-transmitting components of the bone conduction hearing aid of an embodiment are integrated in the housing, the circuit components and the sound-picking components can be integrated in a separate pickup box, and the gap between the shell and the pickup box is Through a certain length of line connection, the circuit between the circuit component and the sound pickup component and the sound transmission component is realized; the sound transmission component, the circuit component and the sound pickup component of the bone conduction hearing aid of another embodiment are all integrated in the shell.

The setting of the hanging ring makes the whole hearing aid device stable and not easy to fall, and at the same time ensures that the sound-transmitting surface of the sound-transmitting component fits closely with the bone behind the user's ear to enhance the sound-transmitting effect.

As shown in FIG. 1 , the bone conduction hearing aid device according to the first embodiment of the present invention includes a casing 1, which can be a hollow plastic part or a partially solid structure, which can be integrally formed or can be composed of multiple components. Combined by bonding, splicing, etc. The housing 1 of the hearing aid device of this embodiment accommodates and installs a sound transmission component 2, which includes a vibrator, and other components such as a soft sound transmission member 21 directly or indirectly connected to the vibrator and installed on the side facing the user's ear. The hanging ring 3 connected to the upper end of the housing 1 includes an arc-shaped upper hanging ring, one end of the upper hanging ring is extended to the position of the sound transmission component 2, and the other end is used to extend around the user's auricle to the front of the user's auricle, Thus, the sound transmission member 2 is fixed and suspended on the user's auricle. As shown in this figure, the shape of the upper hanging ring is similar to the U shape, but it is more suitable for the contour above the user's ear, so that a clamping is formed between the free end extending to the front of the auricle and the end where the sound transmission component 2 is installed on the shell force to clamp the entire hearing aid device firmly to the ear.

As shown in FIG. 2 , the structure of the bone conduction hearing aid device of the second embodiment is similar to that of FIG. 1 . In order to make the wearing more stable, the fitting effect of the soft sound transmission surface 21 of the sound transmission component 2 is better. It has an upper hanging ring as shown in FIG. 1 , and an extension 31 adapted to the contour shape of the ear is provided below the end where the sound-transmitting component 2 is installed on the casing.

On the basis of the bone conduction hearing aid device with the upper hanging ring shown in Figures 1 and 2, in the embodiment shown in Figure 3, the extension length of the upper hanging ring is increased, and its free end can extend into the user's external auditory canal, Therefore, the sound transmission component can be fixedly clamped on the user's auricle. It makes the force on both ends of the bone conduction hearing aid device balanced, and the wearing is more stable. Further, for stable wearing, the free end of the upper hanging ring may also have an inner buckle portion for abutting against the inner wall of the external auditory canal. As shown in FIG. 4 , the structure of the bone conduction hearing aid device of this embodiment is different from that of FIG. 1 in the direction of the hanging ring 3 , that is, the hanging ring 3 connected to the upper end of the casing 1 includes an arc-shaped lower hanging ring. One end extends to the position of the sound transmission component 2, and the wearing method is shown in Figure 4, and the other end is used to extend around the user's external auditory canal along the bottom of the user's auricle, so as to fix the sound transmission component 2 on the user's auricle. . The shape of the lower hanging ring as shown in this figure is also similar to the U shape, but it is more suitable for the contour under the user's ear, so that it extends to the free end of the external auditory canal and the end on which the sound transmission component 2 is installed to form a clamping force to clamp the entire hearing aid device firmly to the ear. According to the specific shape design, the free end of the lower hanging ring can also be inserted into the ear canal hole, so as to isolate the external sound from entering the ear canal and avoid interference with the sound received by the hearing aid device. Similarly, the free end of the lower hanging ring may also have an inner buckle portion for abutting against the inner wall of the external auditory canal.

In addition to the shape of the hanging ring shown in Figs. 1-4, other shapes that partially or completely surround the contour of the user's ear can also be set according to user requirements, which all belong to the protection scope of the present invention.

In the above various embodiments, during the use of the hearing aid device, the sound transmission surface is attached behind the user's ear to make the invisible effect better. Different from many hearing aid devices on the market that set the sound transmission surface at the hip bone in front of the ear, the specific fitting position of the sound transmission surface of the hearing aid device of the present invention can be any cartilage position behind the auricle, or it can be behind the ear. On the skull, such as the mastoid bone, due to the different fitting positions, the shape of the sound transmission surface can also be matched.
