[0008] The device is equipped with a vibrating plate. A PCB board is mounted at the bottom opening of the main body, and a coil is mounted on the PCB board. A magnet is installed between the vibrating plate and the PCB board. The magnet generates a magnetic field under the action of an electric current, which interacts with the coil, causing the vibrating plate to vibrate and thus transmitting sound through the bone. Multiple anti-slip protrusions are provided on the outer wall of the main body. After the bone conduction transducer is worn, these protrusions act on the auricle, increasing the resistance between the transducer and the auricle. This ensures the bone conduction transducer remains stable during use, such as during movement, so that the sound quality transmission is not affected during operation.

[0009] In one or more embodiments of this utility model, the circumference of the main body is set to r, and the width of the main body is set to h.

[0010] In one or more embodiments of this utility model, r is set to 42-52mm and h is set to 20-25mm to fit the area behind the adult ear, thereby improving the comfort of wearing the bone conduction vibrator and the sound transmission efficiency.

[0011] In one or more embodiments of this utility model, the plurality of anti-slip protrusions are configured as arc-shaped protrusions, and the plurality of anti-slip protrusions are arranged in an array, so that the anti-slip protrusions have better contact with the auricle.

[0012] In one or more embodiments of this utility model, the height of the anti-slip protrusion is set to 0.5-1mm, and the spacing between the anti-slip protrusions is set to 2-3mm, so that the anti-slip protrusions are aesthetically pleasing and perform well.

[0013] In one or more embodiments of this utility model, the inner layer of the main body is made of titanium alloy, giving the main body a lightweight and highly elastic property. The outer contact layer of the main body is made of medical-grade silicone, which makes the contact surface between the main body and the human body more flexible and improves wearing comfort.

[0014] In one or more embodiments of this utility model, the silicone cover and the anti-slip protrusion are both made of medical-grade silicone material, which improves the comfort after wearing.

[0015] In one or more embodiments of this utility model, the silicone cover and the PCB board are respectively configured as annular structures that match the upper and lower openings of the main body, so that the silicone cover and the PCB board are fitted onto the main body.

[0016] In one or more embodiments of this utility model, a magnet holder is mounted on the PCB board, the magnet is mounted on the magnet holder, and the magnet holder is used to support the magnet.

[0017] In one or more embodiments of this utility model, a sound transmission cover is installed on the magnet, and the top of the sound transmission cover abuts against the bottom of the vibrating plate, so that sound is transmitted through the sound transmission cover.

[0018] Compared with existing technologies, this utility model optimizes the vibration transmission direction and contact surface pressure distribution through a biomimetic runway-shaped structure design, thereby improving wearing comfort, sound transmission efficiency, and device stability. At the same time, anti-slip protrusions are provided on the outer side of the main body to further improve the stability of the bone conduction vibrator after wearing, resulting in better sound transmission.

The main body 1 is a hollow structure with openings at the top and bottom. The long axis of the main body 1 matches the direction of the temporal bone behind the ear, allowing the bone conduction vibrator to conform to the ear contour during use, thereby improving stability and wearing comfort, while further enhancing sound transmission efficiency. A silicone cover 2 is installed at the top opening of the main body 1. A vibrating plate 3 is installed inside the main body 1, below the silicone cover 2. A PCB board 4 is installed at the bottom opening of the main body 1. A coil 5 is installed on the PCB board 4. A magnet 7 is installed between the vibrating plate 3 and the PCB board 4. The magnet 7 generates a magnetic field under the action of an electric current, which interacts with the coil 5, causing the vibrating plate 3 to vibrate, thus transmitting sound through the bone. Multiple anti-slip protrusions 9 are provided on the outer side wall of the main body 1, so that after the bone conduction transducer is worn, the multiple anti-slip protrusions 9 can act on the auricle. The anti-slip protrusions 9 increase the resistance between the transducer and the auricle, so that the bone conduction transducer can remain stable during use, such as during movement, so that the sound quality transmission is not affected during operation.

[0029] Preferably, the racetrack-shaped design of the bone conduction vibrator conforms to ergonomics, effectively reducing contact pressure and optimizing the pressure distribution on the contact surface of the vibration transmission mechanism, thereby improving wearing comfort, sound transmission efficiency, and device stability.

[0030] like Figure 4 As shown, the circumference of the main body 1 is set to r, and the width of the main body 1 is set to h.

[0031] Preferably, r is set to 42-52mm and h is set to 20-25mm to fit the area behind the ear of adults, thereby improving the comfort of wearing the bone conduction transducer and the sound transmission efficiency.

[0033] Preferably, the height of the anti-slip protrusion 9 is set to 0.5-1mm, and the spacing between the anti-slip protrusions 9 is set to 2-3mm, so that the anti-slip protrusions 9 are aesthetically pleasing and perform well.

[0034] Preferably, the inner layer of the main body 1 is made of titanium alloy, giving it lightweight and highly elastic properties. The outer contact layer of the main body 1 is made of medical-grade silicone, which improves the flexibility of the contact surface between the main body 1 and the human body, enhancing wearing comfort.

[0035] Furthermore, both the silicone cover 2 and the anti-slip protrusion 9 are made of medical-grade silicone material, improving wearing comfort.

[0036] like Figures 1-3 As shown, the silicone cover 2 and the PCB board 4 are respectively set as annular structures that match the upper and lower openings of the main body 1, so that the silicone cover 2 and the PCB board 4 are fitted onto the main body 1.

[0037] like Figure 3 As shown, a magnet holder 6 is mounted on the PCB board 4, and a magnet 7 is mounted on the magnet holder 6. The magnet holder 6 is used to support the magnet 7.
