Bell's success because there will be now on the one hand, the impact from the family because his father and grandfather were well-known linguists. Vocal organs of the body structure, functions and characteristics of hearing people have an in-depth research. Bell lived in this environment, being nurtured from an early age, the transmission of language have had a strong interest, on the other hand, because his specialty is linguistics are, and run-off language schools, the starting point is to help deaf people want to escape the pain only persistent research, these factors and subsequent inventions have a close relationship.I think cell phone in order to people's lives has become a necessity, it gradually become a fashion, a symbol for us to increase the glory of life, brought us convenience, because of its small size, easy to carry, types varied, will have been so popular, I think in the near future, the development of mobile phone will have a better development of future mobile phone will become more intelligent, miniaturized, security, and multifunctional.
