Simply place your fingertip to your ear while speak through the embedded microphone. Replace your existing watch strap with Sgnl and you’re done, whether you wear a classic watch or an Apple Watch, Samsung Gear, or Pebble Time. There’s no one who never lost their earphone in their lifetime. With Sgnl, you can keep your cell phone alone in your pocket and simply raise your hand to answer a phone call without carrying any extra headset or earphone. When you place your finger to your ear, your finger not only transmits the sound but it also blocks out background noise. So you can hear very clear voice in a loud places without worrying about other people listening in.
Hear your caller’s voice simply by placing your fingertip on your ear as you speak through a microphone embedded in the Sgnl strap.
Sgnl receives voice signal from your phone through Bluetooth. When a voice signal is received, Sgnl will generate vibration through its Body Conduction Unit (BCU) which transmits the vibration through your hand to your fingertip. As transmission is made through vibrations, there is no risk of harm to the human body. When you place your fingertip to your ear, the vibration echoes to create amplified sound within the closed space of your ear.
The Blue graph represents the original sound signal, as inputted and the Magenta graph represents sound signals when received through the tip of the fingertip. In the transmission of speech, the voice frequency ranges approximately around 2000 Hz. Within this range, the sound signals through the fingertip don’t show much variation from the original inputted sound signal.Read more..
