Description

Technical Field

[0002] Hearing health testing devices refer to equipment used for hearing testing. Existing hearing health testing devices:

[0003] The patent document with publication number: CN216365038U discloses a hearing detection device based on bone conduction, including a base, a sliding block, a mounting arm, a driving mechanism, an earmuff, a flip mechanism, and an arc plate. The arc plate is provided with a plurality of brain electrode sheets on the side facing the earmuff, and a bone conduction earphone is provided on each of the outer walls of the opposite sides of the two mounting arms. The two sliding blocks are relatively close to each other, so that the two bone conduction earphones are in contact with the ears of the child, and the hearing detection based on bone conduction can be performed. In addition, because the two mounting arms can limit the child's head to a certain extent, the child's head is prevented from swinging and affecting the detection. The other two earmuffs are driven to swing by the flip mechanism and can cover the child's ear canal opening, thereby improving the detection quality. In addition, because the flip mechanism can buffer the process of the earmuffs contacting the child, it is avoided that the child's ears or face are squeezed and uncomfortable.

[0004] However, the above detection device lacks a mechanism to attract children when in use, and children move around during the detection, which is not conducive to the detection work. Therefore, we propose a hearing health detection device based on bone conduction to solve the above problem. Utility Model Content
