Smart phone should be equipped with high end speakers

iPhone Case

Smart phone spell, spell screen, spell processors do you forget something? Foreign science and technology media recently said, in these configurations is big step forward, but forgot to another – audio technology and cell phone speakers. This might become the focus of a Smartphone, to give consumers a better music experience. Ted Baker iPhone 6

Foreign Media summary: prior to this Smartphone seems to ignore the audio quality and speaker equipment. Authors put forward their views, you can follow the Tablet treatment, put the speakers on the sides of the fuselage, so that you can create a stereo effect. Following is the full text of the translation: Ted Baker iPhone 6 cover

Now to the end of, when we look at 2011 and 2012 smartphones and contrast, Smartphones have changed? Here is I of summary: screen became more big has, on in this year iPhone of screen are variable big has, this is Qian years are never some, PPI also has has huge upgrade can displayed more of details; and operators also in active promotion LTE 4G high-speed network (beauty Emperor people you understand of); system in details aspects more of perfect, interface also more smooth, has more convenient of function. But they seem to ignore the aspect is all the audio technology does not seem to be valued.

Smart phone should be equipped with high-end speakers

• HTC has attached great importance to mobile music experience

Said that if a single manufacturer in audio technology have been maintained a strategic plan seems only HTC, but as far as I know, HTC is not in the audio, music played well on this point. It’s not about the brand, or that provides headphone devices isn’t good enough; but they should spend more time on the design of a mobile phone, especially the internal structure of the design, allow speakers to play a better, more realistic stereo sound.

For example recently An Zhuoji–Nexus of fire 4, this machine runs very smooth, system software, user experience is very good. But this machine’s speakers to play the effect is really bad surprise, people find it difficult to accept. I have to say, speaker volume is very large, but the audio response effect is really very bad; even if you use high-end headphones to listen to music, you could hardly hear rich bass effect.

I are not very demanding. In Samsung Galaxy Music, for example the equipment on the outside with excellent results, but in smartphones is hard to have such a good situation. And it makes me feel very important, is not easy to achieve this audio effects, much of the work is not so obvious is not on the outside.

Of the solution: follow the example of flat-panel speaker design

Smart phone should be equipped with high-end speakers
Smart phone should be equipped with high-end speakers

But another trade effects is to help solve some flat handles, flat because there is enough space, tends to edge of the speaker can be placed on the sides of the fuselage, which means both speakers. Due to its ample space, so the manufacturer can very well arrange audio components to achieve better results. This phone is very different, because the phone is compact in structure, often need to put speakers in front under the screen and compact get and other parts together. But that does not mean there is no solution on the phone, I still believe that companies can find ways to overcome the problem. From the devices I’ve tested it, flat-panel speakers than a notch on the phone well.

Smart phone should be equipped with high-end speakers

Use border outside audio design can also be very good stereo problem, because when you need when playing a stereo, left and right speakers to play music may differ, and this design can well reflect the musical differences and creating a more realistic stereo sound. And if the two trumpet from the far outside audio, stereo effect can be better.

To mobile phone manufacturers, and now is the time to consider better audio performance. Because I think in terms of reducing the thickness of the phone was near the end, in fact, increased thickness of the phone can increase the number of battery capacity battery, cell phone screen is not only can have a larger battery, but also to outside phone with better equipment to play a better sound quality. What I mean is: manufacturers not to put aside whatever audio technology, make better audio playback, consumers would really like that.

Origin legend

About the origin of yuxian, folk tales very much. It is said that long ago, city, Wei Wang, and a Taoist priest, who used a pair of scissors and knives cut colored paper, superb. Later, two people engaged in paper-cutting workshop, a paper-cutting, staining, with the tacit understanding. So-called carved knives, incised, see color, styling with classes applied color will gradually create handmade delicate, colorful form of yuxian. This form of color paper-cuts, along with transportation developed and frequent civil exchanges, then spread to all over.

Apple Apple Car launch will be extended to 2021

Uncategorized

Beijing time on July 22, according to the online edition of Fortune reported, although technically Apple Car does not yet exist, but media reports said it published has bounced.

The Information published an article citing sources said Apple’s own-brand cars will be released until 2021. More rumors are claiming that Apple plans to release in 2020 Apple Car, but according to The Information people give, the project “challenged” Project Titan, a former member of the team confirmed that Apple has Apple Car plans to release from 2020 to be deferred to the year 2021. Project Titan team responsible for developing Apple Car.

Apple Apple Car launch will be extended to 2021

The past few years, there have been media reports that Apple was in the development of automatic driving electric vehicles. Although Apple has not confirmed media reports, company CEO Tim Cook (Tim Cook) kept quiet about the Apple Car topics, from Project Titan team is a lot of rumours, Tesla’s CEO ailong·masike (Elon Musk) Apple project, called Silicon Valley “confidential secret of the worst,” he even called Apple “Tesla’s gravedigger.”

Analysts said Apple needs a major innovation of the new product, car can play this role.

However, compared with the development of new smart phones or computers, and develop cars much harder, and for Apple, the car is a new field. Media reports said Apple engineers with experience in hiring large numbers of cars, the company leader qiaoni·aiwei (Jony Ive) is also studying car design. Moschino iPad Air Case

Some veteran cars in China was critical of Apple building cars. Former GM Chief Executive Officer Dan·akeersen (Dan Akerson) said last year that because of the high cost and low return, Apple should not build cars. Former GM Executive Bob Lutz (Bob Lutz) last September, told CNBC that Apple will face “huge money trap” threat, “Apple has no experience in automobile industry, has no reason to believe that the Apple than General Motors, Ford, Volkswagen, Toyota and Hyundai have done better”.

Design of UAV flight control systems and how

Uncategorized

Lei feng’s network (search for “Lei feng’s network”, public interest): the author drones channel (ID:auscor), concerned the drones.

Is the core of UAV flight control system control unit, equivalent to the drone’s brain, fitted with flight control system model is no different from that of common air, an important symbol.

After early r/c flying in, and its navigation and intelligent flight control modes have been developed for autonomous flight. Navigation changes on accuracy of the flight control computers put forward higher requirements; with the increasing complexity of UAV mission, flight control computer requirements are also higher operational speed and miniaturization requires flight control computer power and volume are also put forward higher requirements. High precision not only requires a computer with a high control precision, but also capable of running complex control algorithms, miniaturization requires UAV’s small size, good mobility, and control the size of the smaller the better.
