Description
Technical field
The utility model belongs to bone conduction earphone technical field, and in particular to a kind of bone conduction earphone.
Background technique
Osteoacusis is a kind of sound conduction mode, i.e., converts sound to the mechanical oscillation of different frequency, passes through the cranium of people
Bone, osseous labyrinth, inner ear lymph transmitting, spiral organ, auditory nerve, auditory center transmit sound wave.It is generated relative to by vibrating diaphragm
The step of classical sound conduction mode of sound wave, osteoacusis eliminates the transmitting of many sound waves, can be realized clear in a noisy environment
Clear sound-reducing, and sound wave will not influence other people because of spreading in air.
The principle of sound of bone conduction earphone is to be produced voice signal by contact human body skull using the vibration of vibrating loudspeakers
Raw vibration, carries out sounding for the mode that voice signal is transmitted to auditory nerve.Based on this principle of sound, vibrating loudspeakers must be tight
The hearing effect that the skull of patch people could generate, optimal selection are exactly the cheekbone on front side of human skull's ear.In order to enable
Vibrational energy is absorbed by the skull of people as far as possible, and bone conduction earphone needs to select to have the hard support connection of certain elasticity, so that bone
