Description

Technical Field

[0001] The utility model relates to the technical field of earphones, and more specifically to a racetrack-shaped bone conduction vibrator. Background Art

[0002] Bone conduction headphones are a special type of headphones that use bone conduction technology to transmit sound to the auditory nerve instead of transmitting sound through the traditional ear canal and middle ear. The working principle of bone conduction headphones is to transmit sound to the skull through vibration, and then conduct it to the inner ear through the bones, allowing the user to hear the sound; bone conduction headphones are widely used in many fields, including sports, medical, military, etc. In the field of sports, bone conduction headphones allow athletes to maintain awareness of the environment and enhance safety when doing outdoor activities. In the medical field, bone conduction headphones can help the hearing-impaired restore some hearing function. In the military field, bone conduction headphones can keep communications clear in environmental noise such as gunfire.

[0003] The vibrator in bone conduction headphones refers to the element responsible for converting sound into mechanical vibrations. It is usually one of the key components for transmitting sound to the auditory nerve through bone conduction technology. The role of the vibrator is to convert the audio signal from the sound source into mechanical vibrations. These vibrations are transmitted to the inner ear through the bones, bypassing the traditional ear canal and middle ear, directly stimulating the auditory nerve, allowing users to hear the sound. The vibrator in bone conduction headphones is usually made of magnetic materials, such as vibration motors, vibration sheets, etc. When the audio signal is transmitted to the vibrator, its internal magnetic field is controlled, causing the movement of the vibrator. This movement generates mechanical vibrations, which transmit the sound to the inner ear through contact with the skull.

[0004] The inventor believes that it is difficult for the bone conduction headphone vibrator in the related art to maximize the performance of the material components in a small space, and it is difficult to ensure the sound performance when the product volume is reduced. Based on the above problems, we provide a racetrack-shaped bone conduction vibrator.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content

[0006] In order to solve the problems raised in the above background technology, the utility model provides a racetrack-shaped bone conduction vibrator.

[0007] The track-shaped bone conduction vibrator provided by the utility model adopts the following technical solution:

[0008] A racetrack-shaped bone conduction vibrator comprises a bracket; a U-shaped iron mounted inside the bracket, the outer portion of the U-shaped iron being sheathed with a spring sheet, and the side surface of the spring sheet extending into the inner wall of the bracket; a magnet mounted at the top center of the U-shaped iron, the top of the magnet being mounted with a first magnetic conductive sheet, and the top of the U-shaped iron being mounted with a second magnetic conductive sheet; a pad bracket mounted on the top of the bracket, the bottom of the pad bracket being mounted with a coil, and the first magnetic conductive sheet and the magnet are both arranged in the coil; a pad mounted in the pad bracket.

[0009] Preferably, the number of the pads is two.

[0010] Preferably, the bottom of the bracket is also equipped with a protective cover.

[0011] Preferably, the outer edges of the bracket are rounded.

[0012] Preferably, the pad is matched with a pad bracket.

[0013] In summary, the utility model includes the following beneficial technical effects:

[0014] After power is supplied through the pad, resonance will be generated through the magnetic field of the coil and the magnet. Vibrations of different frequencies will be generated through specific frequencies. Sound will be emitted after the vibration frequency is transmitted through the medium. Through the special-shaped design, the U-shaped iron mouth and the spring are connected through the pole ring (composed of the first magnetic conductive sheet and the second magnetic conductive sheet). The performance of the material components can be maximized in a very small space, and the product volume can be reduced while the performance is improved. Vibrations are generated through changes in the coil and the magnetic field, driving the resonance of the solid medium to transmit sound.

In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
