[0015] (III) Beneficial Effects

[0016] This invention provides a piezoelectric bone conduction hearing aid device, which has the following beneficial effects:

[0017] 1. This piezoelectric bone conduction hearing aid, through the setting of protective and sealing components, when in use, the torque force generated by the torque spring causes the protective door to close. The torque force of the torque spring is greater than the force generated by the compression spring, so that the protective door contacts the sealing gasket. At this time, the compression spring is in a compressed state and provides a reaction force. Because the torque force of the torque spring is greater than the force generated by the compression spring, the sealing gasket and the protective door are tightly fitted, thereby preventing moisture or dust from entering the interior of the charging port and avoiding short circuits or other damage caused by moisture corrosion or dust accumulation.

[0018] 2. This piezoelectric bone conduction hearing aid features a sweat-absorbing component. During use, the sweat-absorbing pad absorbs sweat from the contact surface between the device and the user. After a period of use, the sweat-absorbing pad can be removed from the device, separating adhesive plate A from adhesive plate B. A new sweat-absorbing pad is then placed inside the mounting slot, with adhesive plate B on one side of the pad adhering to adhesive plate A for fixation. This allows for easy replacement of the sweat-absorbing pad, keeping the contact surface between the user and the device dry, reducing discomfort caused by sweat, and improving wearing comfort.

A counterweight box 7 is fixedly connected to the other side of the connecting frame 1. An installation groove is provided on one side of both the control box 2 and the counterweight box 7. A sweat-absorbing component 5 is provided inside both sets of installation grooves to keep the contact surface between the device and the user clean. The drying and protection assembly 3 includes a fixing post 301 disposed on the surface of the control box 2. Torque springs 302 are disposed on both sides of the fixing post 301. Connecting posts 303 are disposed on the outer sides of the two sets of torque springs 302. A protective door 304 is fixedly connected to one side of the two sets of connecting posts 303. The sealing assembly 4 includes several sets of compression springs 401 disposed inside the placement groove. A sealing gasket 402 is fixedly connected to one end of the several sets of compression springs 401. The two sets of sweat-absorbing assemblies 5 each include two sets of adhesive plates A501 disposed inside the installation groove. Adhesive plates B502 are adhesively connected to the surface of the four sets of adhesive plates A501. Two sets of sweat-absorbing pads 503 are fixedly connected to one side of the four sets of adhesive plates B502.

[0027] The connecting frame 1 has a fixing groove inside, and a reflector 6 is fixedly connected inside the fixing groove. The reflector 6 enables the device to be quickly located in the dark.

[0028] The bottom of the control box 2 is equipped with an adjustment button 8, and a switch button 9 is provided on one side of the bottom of the control box 2. The volume can be adjusted by adjusting the adjustment button 8.

[0029] The top surfaces of both the control box 2 and the counterweight box 7 are fixedly connected with connecting blocks 10, and one side of each of the two sets of connecting blocks 10 is fixedly connected with a connecting frame 11. The connecting frame 11 serves to connect the transmission block 12.

[0030] One end of each of the two sets of connecting frames 11 is fixedly connected to a conductive block 12, and one side of each of the two sets of conductive blocks 12 is fixedly connected to a silicone pad 13. The silicone pad 13 helps to reduce the damage to the human skull caused by excessive amplitude.

[0031] The inside of the placement slot is provided with a charging port 14, and the inside of the charging port 14 is provided with several sets of guide posts 15. The charging port 14 serves to charge the device.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: During use, the torque force generated by the torque spring 302 causes the protective door 304 to close. The torque force of the torque spring 302 is greater than the force generated by the compression spring 401, causing the protective door 304 to contact the sealing gasket 402. At this time, the compression spring 401 is in a compressed state and provides a reaction force. Since the torque force of the torque spring 302 is greater than the force generated by the compression spring 401, the sealing gasket 402 is tightly fitted to the protective door 304, thereby preventing moisture or dust from entering the interior of the charging port 14.

[0035] The second step: When in use, the sweat pad 503 is used to absorb the sweat generated on the contact surface between the device and the user. After the device has been used for a period of time, the sweat pad 503 is peeled off from the device, the adhesive plate A501 and the adhesive plate B502 are separated, and the new sweat pad 503 is placed inside the mounting slot. The adhesive plate B502 on one side of the sweat pad 503 is attached to the adhesive plate A501 for fixation, so that the device can replace the sweat pad 503.
