Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an earphone vibrator structure and a headphone. Background Art

[0002] Bone conduction headphones utilize bone conduction technology to transmit sound. Bone conduction is a method of transmitting sound directly to the auditory nerve through the skull, bypassing the ears. Instead, it is transmitted through the skull and bony labyrinth (lymphatic fluid in the inner ear). Bone conduction technology was first used in the military and medical fields to help those with hearing loss regain their hearing. In recent years, with the continuous advancement of technology, bone conduction headphones have gradually entered the consumer market. The principle of bone conduction headphones is to convert electrical signals into mechanical signals, which are then transmitted through the skull to the auditory nerve.

[0003] When the earphones are working, the vibrator will vibrate. When the vibrator vibrates back and forth, it may not be able to keep in contact with the auditory bones at all times, which may affect the conduction of sound.

[0004] For example, Chinese patent application number CN202321958854.1 discloses an earphone with a composite structure vibrator head. When the vibrator of such earphone vibrates, the vibrator may not always be in contact with the auditory bone, which will affect the conduction of sound.

[0005] Another example is the bone conduction earphones disclosed in Chinese patent application number CN202010889626.8. When the vibrator of such earphones vibrates, the vibrator may not always be in contact with the auditory bones, which affects the conduction of sound. Utility Model Content

[0006] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide an earphone vibrator structure, the vibrator of which can always fit with the auditory bones to ensure normal sound conduction, thereby overcoming the shortcomings of the prior art.
