Elastic piece and bone conduction sound production device

Abstract

The invention discloses an elastic piece and a bone conduction sound production device, the elastic piece comprises an external component, an internal component and a plurality of connecting components connected between the external component and the internal component, and the minimum width of the connecting components is not less than the wall thickness of the connecting components. The minimum length of the connecting assembly is not smaller than two times of the distance between the external assembly and the internal assembly, the resonance frequency point F0 of the elastic piece is effectively reduced, and the optimal low-frequency effect is achieved. According to the bone conduction sound production device applying the elastic sheet, the whole sound frequency band is balanced, a good acoustic effect is achieved, and the user experience and the product sound quality are remarkably improved.

Description

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

AI Technical Summary

Problems solved by technology

[0004] When the bone conduction sound generating device used in the existing bone conduction earphones transmits low-frequency signals, because the resonant frequency point F0 of the existing shrapnel is relatively high, the low-frequency parts heard by the ears will not sink enough when the earphones are playing, and the sound will be restored. The degree of vibration is not good, resulting in a large vibration amplitude, and a strong sense of vibration when using it, which affects customer experience

In order to overcome the above defects, the earphone will directly shield the low-frequency signal in actual application. 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's experience.
