Description

Colour Name:Anti Blue Ray What is bone conduction? 🔹We hear bone conduction sound while eating,drinking and scratching our head,etc.We also hear ourselves talking partially through bone conduction.That's why we perceive our own voice differently from what other people hear.Taking advantage of this natural phenomenon, bone conduction transducers guide micro-vibration through the cheekbones to the inner ears, delivering sound without plugging or covering them. How to distinguish true and false bone conduction? 🔹Block your ear,if the sound is louder when the ear is blocked,it is a bone conduction.Otherwise it is a speaker!(The principle is that the bone conduction propagation mode is a way to block the air transmission.)
