A lot of people can’t sleep well because of the noise.To solve the problem, we have designed the rings that can weaken the sound. The electronic rings can send out wave,which can weaken
the sound wave.Wearing the soundproof rings,we won’t be disturbed by the noise.Then,we can
have a good sleep.Besides,we can also wear it when we are in the noisy bus or subway to reduce
the harm of noise.
