[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] The utility model embodiment discloses a dual-magnetic field bone conduction hearing aid.
[0025] Reference Figure 1-4 A dual magnetic field bone conduction hearing aid comprises a hearing aid body 1 and a back pillow 3. The two hearing aid bodies 1 are symmetrically arranged. The back pillow 3 is arranged on the rear sides of the two hearing aid bodies 1. The back pillow 3 is a rubber strip for easy bending. A thermal insulation layer 4 is fixedly arranged on one side of the back pillow 3. The thermal insulation layer 4 is flannel, which is warmer when worn. A cooling layer 5 is fixedly arranged on the other side of the back pillow 3. The cooling layer 5 is silk, which is cooler when worn. A connecting block 2 is fixedly arranged on one side of the two hearing aid bodies 1 close to the back pillow 3. A wedge-shaped groove is opened on the upper side of the connecting block 2. Wedge blocks 6 are fixedly arranged on both ends of the back pillow 3. The two wedge blocks 6 are both engaged with the corresponding wedge-shaped grooves.
[0026] Reference Figure 1-4A limiting mechanism for limiting the movement of the wedge block 6 is provided on the upper side of the two connecting blocks 2. The limiting mechanism includes a U-shaped rod 8 and a limiting block 7. The two U-shaped rods 8 are respectively arranged on the upper side of the corresponding wedge block 6, and multiple limiting blocks 7 are movably sleeved on the two ends of the corresponding U-shaped rods 8. One side of the multiple limiting blocks 7 is respectively fixedly connected to one side of the corresponding connecting block 2. A cavity is opened at the lower end of the U-shaped rod 8, and a slider 10 is slidably arranged inside the cavity. A clamping block 11 is fixedly arranged on one side of the slider 10, and one side of the clamping block 11 extends to the outside of the cavity. A through hole is opened on one side of the limiting block 7, and one end of the outer side of the clamping block 11 is clamped with the through hole.
[0027] Reference Figure 1-4 A spring 9 is fixedly provided on one side of the slider 10 away from the block 11, and the other end of the spring 9 is fixedly connected to the inner wall of the cavity, so that the block 11 is more firmly connected to the through hole. The longitudinal sections of the slider 10 and the cavity are both rectangular, so that the slider 10 cannot rotate, that is, it can slide stably.
[0028] In the utility model, when in use, the card block 11 is pushed into the cavity to release the limit between the U-shaped rod 8 and the limit block 7, and then the U-shaped rod 8 is pulled out from the limit block 7 to release the limit on the wedge block 6, and the wedge block 6 can be pulled upward out of the wedge groove to complete the separation of the back pillow 3 and the connecting block 2, and the different materials on both sides of the back pillow 3 can be adjusted to the inside. In summer, the cool silk is adjusted to the inside, which is more breathable and cool. In winter, the flannel is adjusted to the inside, which is softer and warmer, that is, different materials are used to fit the skin in different seasons, which can improve the comfort of equipment use.
