I in the development of "518 supermarket broadcast software" (http://www.518boyin.com/), a design with place, is the range of speed, the vast if [- 10, 10], afraid of user accidentally transferred slowly or quickly, completely can't listen to, also don't know what the reason, is a very small white, some users if the smaller range [2, 2], can listen to how to adjust, but, if the individual users is very slow very slow speed, while the user is few, this is a kind of struggle, the solution is as follows,
1. The speed range for [8, 2], is of little use since the speed is too fast, but the speed is slow, some users wish to slow, English might be useful,
2. The normal range is [2, 2], if the user's speed setting beyond this range, prompt said "low speed - 8, the normal speed [2, 2], confirm correct?"
Through the above way, basic can solve the problem,
