Detailed Product Description

Portable speaker:

1>The size of our product is only as the size of a purse before unfolding. When unfolding, the size can be 10 times the size when folded. Usually the Fo of a 3- speaker is 180HZ. But when using our leather-cavity technique, the Fo can reach 60HZ and effectively increase the bandwidth to make the timbre more beautiful. The Fo of speakers can be effectively lowered by using this leather-cavity technique, which is our patent. The general little speaker cannot be made in a very small size is because of the problem of cavity volume, while the compression ratio of a leather cavity can reach 1:20, which solve this problem perfectly. Thats why our products can be in the smallest size with the best tone quality to be portable in an easy way
