Detailed Product Description

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 F0 of a 2- speaker is 200HZ. But when using our leather-cavity technique, the F0 can reach 160HZ and effectively increase the bandwidth to make the timbre more beautiful. The F0 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

2>It is suitable for MP3\MP4\portable computers when they are working outdoors.

3>It also has perfect and as much as over 10 different kinds of protective functions, such as over-voltage, over electric current, over- heat, short circuit, etc. It is coated with metal lacquer. It looks fine and delicate. It meets consumers needs for fashion and unique.
