Description

technical field [0001] The invention relates to the technical field of bone conduction sound generation, in particular to a bone conduction sound generation device and a wearable device. Background technique [0002] Bone conduction is a method of sound conduction, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph, auger, and auditory center. Compared with the traditional sound conduction method that generates sound waves through the acoustic membrane, bone conduction saves many steps of sound wave transmission, and can achieve clear sound restoration in a noisy environment, and sound waves will not affect others due to diffusion in the air. . [0003] The earphones manufactured by the application of bone conduction sound technology are called: bone conduction earphones. The conduction of sound waves is different from the ordinary in-ear type. It does not require the v...

Problems solved by technology

[0004] The bone conduction sounding device used in the existing bone conduction earphones will generate a large vibration amplitude when transmitting low frequency signals, and has a strong vibration feeling when using it , affecting customer experience

Therefore, in order to overcome the above-mentioned defects, the earphone will directly shield the low-frequency signal in practical applications. Although this reduces the vibration, the sound transmitted to the ear lacks the bass part, and the sound quality is not high, which will also affect the customer experience. feel
