The utility model is proposed based on following problems of the prior art:
It is enough for the application in the global big face of smart phone, feature-rich, has the support of numerous application software, makes
Smart phone function it is very rich, directly penetrate into the every aspect of people's Working Life, have become one can not or
Scarce carry-on tool.Have benefited from the technological progress of mobile communications network, 2G/3G/4G and 5G mobile communication standard it is gradually general
And so that more and more application is desirably integrated into smart phone, such as application mobile navigation most burning hot at present, mobile branch
It pays, move instant communication software, mobile social application, mobile communication, mobile news media, mobile film program request etc., we
The various functions that daily life can not almost be left are innumerable.There are also portable medical, the mobile AI, shifting in fermenting and starting to walk
Dynamic VR, etc. a series of function, future all can greatly enrich our life.
As long as current smart phone is towards young man, almost without the elderly's smart phone is directed to.Such as it is Huawei, small
Rice, the domestic leading cellphone enterprise such as association, built-in old man's mode, is exactly that icon size is big by one nothing but inside mainstream mobile phone
Point, font size are slightly bigger, it may be said that have a little looked after old Man's Demands, but needed from old man's core really
It asks and also greatly differs from each other.
It is sold on the market there are also a kind of special older mobile phone, is mainly characterized by having looked after the core at this stage of older mobile phone
Heart demand, but basic this kind of product are all to be transformed by functional mobile phone (non-smart mobile phone), only have basic call
With function of sending short messages, better band just like flashlight, the functions such as listen to music, simply take pictures, do not have network communication generally, more
Function without installation application program.
It causes the application of countless numerous primary mental ability mobile phones on the market, can not all realize in celephone for the old again, old man uses
At present the smart phone designed for young man, there is inconvenience；Using dedicated celephone for the old, functionally there is a serious shortage in the supply, Lao Renyu
The communication of children can only be using short message form of having made a phone call, the problem of encountering for old man, if can pass a scene with wechat
Photo, it is believed that describe situation with pale speech than making a phone call come convenient more.
So be badly in need of wanting on the market a suitable old man uses can only mobile phone, but under present case, cell phone manufacturer is not
It is ready that flower is special energetically and develops the smart phone for being suitble to old man, in the vast old man group using mobile phone in China, based on rural area,
Substantially be also limited in the expense of bull's machine, though have manufacturer develop suitable old man can only mobile phone, be limited to cost
And sales volume, estimation selling price will not be too low, and sales volume naturally can be more difficult, and with Social Development of China process, it is now old
The ratio that people occupies in crowd is quickling increase, on the market from now to coming few decades, being all badly in need of wanting such product, 20
Nian Hou, I also requires such product for you.
With the high speed development of social economy, present young man is more demanding to the update of mobile phone, young crowd
Used mobile phone is just directly changed in the case where various performances are also very excellent, if the mobile phone that young man is changed be subject to it is low
Cost transform the intelligent machine used suitable for the elderly as, and low in cost, price material benefit can benefit vast old consumption
Person improves the reasonable utilization of social resources.
Most of old man has dysaudia, to the susceptibility of sound far below young man, so old man's intelligence hand
One of key problem of machine is exactly that sound is big, and loudspeaker are big, and sound is loud and clear, it is desirable that even if mobile phone is mounted in the inner layer of cotton dress, noisy
Environment noisy as food market in, gem-pure can also hear cell phone incoming call the tinkle of bells, can be clear after answering the call
Hear incoming call other side speech, this requires typhon, stentorian feature；Existing universal intelligent mobile phone, none
Money can satisfy such requirement.It is all that sound is too small, the tinkle of bells be can't hear at all under noisy environments, and making a phone call can only be close to
Ear is listened, even if there is so-called hands-free mode, can only also be used under relatively quiet environment, do not deal at all food market this
The environment of sample.Older mobile phone key problem two is exactly to need noise reduction microphone of good performance, as described in preceding article scene, noisy
Under environment, old man ability to speak itself is a bit smudgy, and the volume spoken is smaller, and to accomplish being capable of call freely, it is necessary to
There is the excellent benefit of decrease of noise functions, high-gain can receive main acoustic information, filter out the excellent Mike of the function of environment noise
Wind；Equally, smart phone is designed with young artificial target group on the market, be not directed to old man's handling characteristics to this part and
Design.
Therefore, the utility model, which provides one kind, inexpensive to obtain the portable outer connection for the smart phone that old man uses
