A
They are the fashion statement loved by hip hop stars and rappers.But now it seems that grilles(金属网罩)—teeth jewellery loved by rappers such as Nelly—are not just about the way you look—you can use them to listen to music，too.
A design student has created a way of using the jewellery mouthpiece to hear songs by means of “bone conduction” through your skull.Aisen Chacin，of Parsons The New School for Design in New York，attached a vibrating(振动)motor to a digital music player and connected it to a mold(模子)of her upper teeth.She also placed controls on the underside so users can change songs or increase the volume by pushing up with your tongue.When the music starts，the vibration is strong enough that the music can be heard clearly—without the need for headphones.If the sound being played is loud enough，others can even hear it apparently coming out of your teeth.A video posted on YouTube shows one of Chacin's friends sitting down with the motor in his mouth and his hands in his ears.He didn't believe his eyes when he heard the music.
Grilles were made popular by the song by rapper Nelly even though dentists have made warnings against them.They say jewellery materials like gold or diamonds can wear down the enamel(牙釉质)on your teeth and that grilles should not be worn.
Chacin showed her device，called Play-A-Grill，at the New Interfaces for Musical Expression conference last week.She said，“Grilles are almost always made of precious metal.They are completely removable，and almost used as a grill.Because the grill is worn over the teeth，sound can be spread using bone conduction hearing
