The microphone/bug (as part of a modification to Conan's [glasses](/wiki/Criminal_Tracking_Glasses "Criminal Tracking Glasses")) is the third gadget created by [Professor Agasa](/wiki/Hiroshi_Agasa "Hiroshi Agasa") for [Conan](/wiki/Conan_Edogawa "Conan Edogawa").
## Description[[edit](/wiki/index.php?title=Microphone&action=edit&section=1 "Edit section: Description")]
Agasa altered Conan's glasses to include a miniature hidden microphone, enabling Conan to hide a microphone/bug somewhere and listen in to conversations by matching the frequency on his glasses.
The science behind the microphone is that the glasses emit vibrations that stimulate Conan's eardrums. [This technology exists in real life.](http://en.wikipedia.org/wiki/Bone_conduction "wikipedia:Bone conduction")
