Vocal Bible / microphone

Vocal Bible
Vocal Bible

Vocal Bible is a smart microphone. Once the user input the song data, Vocal Bible will check and compare your pitch with the real song by the Tuner embedded in the mike. System also has the rule to calculate scores as shown in pictures. Users will feel that singing is more fun through playing this vocal game. Not only the pitch, but also the Tempo, Volume is also considered. Once the user gets wrong, system will warn by vibrating.
Besides, the microphone holding style is different, just depended on each one’s habit. So we design this shape of looks for Vocal Bible. User can feel more comfortable with their style, then sing much more better.
