Now there are more and more types of headphones, for example Bluetooth Headsets, In Ear Earphones, Earbuds Earphones, Computer Headphones, Headband Earphones, Metal Earphones so on. In recent years the Noise Cancelling Headphones and Bone Conduction Headset. Today we're gonna focus on Bone Conduction Headset.
Bone conduction is a conduction mode of sound,it change the sound into a different frequency of mechanical vibration.Transmit the sound through human skull,bone lost,Inner ear lymph fluid delivery,spiral,auditory nerve, auditory center transfer sound waves.
Compare with classic conduction,bone conduction eliminates many steps of acoustic transmission.Achieve a clear sound in a noise evnironment.And the sound waves will not affect others when spread on the air.Bone conduction technology is divided into bone conduction speaker technology and bone conduction microphone technology.
(1)Bone conduction speaker technology use to receive call.send call.Air-borne speaker is the electrical signal into sound waves (vibration signal) transmitted to the auditory nerve.The bone conduction speaker is the electrical signal into sound waves (vibration signal) directly through the bone to the auditory nerve.
The transmission medium of acoustic waves (vibration signals) is different.
(2)Bone conduction microphone technology used to send call, send calls that is collected sound.Air conduction words are sound waves transmitted through the air to the microphone,and bone conduction to send directly through the bone transfer.
