SONY will also begin to sell the first digital active noise reduction headphones: MDR-NC200D will cost 24,675 Yen, MDR-NC100D at 18,375 yen.

MDR-NC200D

NC200D digital active noise reduction function, can pass the microphone noise around collecting, gathering to analog noise signal through ADC digital waveform signal is generated and analyzed, and then generated by DNC digital noise reduction engine built-in to counteract noise, anti-trust, depending on the use environment has three modes of AI intelligent noise reduction, also joined the S-Master digital amplifier to reduce distortion. Allegedly this technique more effective than direct simulation approach to noise, noise reduction can be achieved 98.2% (about 17.5dB) effect. At the same time, in order to avoid the low frequency noise reduction of State NC200D plus digital equalizer, to reduce this effect.

NC200D seal type moving coil design, diameter 40mm CCAW drive units, the maximum input power 50mW, frequency response range 8Hz~23kHz. When the power is turned on it is 68 ω of impedance, sound pressure sensitivity of 103dB/mW, shut down the power supply impedance 35 ω, sound pressure sensitivity of 102dB/mW.

Over the previous NC600D (including an earlier NC500), the new NC200D an improvement is in the case of no electricity but also can be used when normal headphones. Noise reduction of State life has improved, simply by a AAA battery-powered, sustainable use of 22 hours.

NC200D main structure more compact, headset can be flipped inside are flush design, keyed using elastic polyurethane foam material, total batteries weight about 180g. Medial can collapse, included in packed boxes.

NC200D l-shaped gold plated stereo plug, removable cable length of 1.2 m. Standard accessories include 30 centimetre-long extension cord, aircraft transfer the plugs, portable box and AAA alkaline batteries.

RS-BTV25 and RDP-V20iP these two speakers at the same time equipped with a 2.2-inch bass unit and 0.78-inch tweeter, by providing 13W ultra high power AC adapter can be. RDP-V20iP through the Ni-MH rechargeable battery provides up to 5 hours of life, but in that case, only 4W output power, sound quality volume discounts. Because it is from the hand of Sony, low frequency enhancement natural integral, 3.5mm audio input connector is standard equipment, so two speakers of the device limitation vanish into thin air. Both are 145 x 145 x 145 mm,RDP-V20iP SRS-BTV25 weight by the weight of 600 grams to 500 grams, only black and white two colors can be selected, but RDP-V20iP will have the Red version introduced later, I said that Sony did you had no more engaged in several colors, do not let consumers down!

Apple co-founder Steve Wozniak said in an interview today that Steve Jobs has proven himself as the the greatest scientific and technological leader who  helped Apple’s “outstanding performance in the finance.

Wozniak said: “He introduced the iPhone. My God. Once you have this equipment, do not want nothing.”

Wozniak said he did not communicate frequently with Steve Jobs, the health status of the latter is only slightly known. He supports the Apple product development practices strict confidentiality, that this is Apple’s surprise, one of the key success factors.

　　Speaking at Apple’s start-up period, Wozniak said Steve Jobs want to have a successful company and “known to the world.”

　　Apple’s last quarter net profit of $ 7.3 billion, compared with $ 3.3 billion over the same period last year more than doubled. Wozniak said: “Apple no longer marketable in the production of only a poor product will be a loss.”

Apple is trying to remove external antenna in the product so that users don’t realize antennae exist in Apple products. Apple’s latest obtained a patent describes a method of integrated antenna in a MacBook and iMac keyboard, that the antenna is placed under the keyboard number keys.

According to Patently Apple website reports, this is the 4th and obtained in the past year of Apple MacBook connectivity mobile phone network-related patents, is also the 2nd antenna-related patents. This means that Apple may launch in the future to support 3G or 4G MacBook.

Apple has realized that design and placement of antennas in the device is very important. Last summer, users found iPhone 4 present obvious signal reception problems, when users hold the iPhone 4 some locations will cause call drop. In addition, the MacBook Pro users have found difficulties when connecting Bluetooth accessories. This is mainly because the Bluetooth antenna in the MacBook where there is a problem.

Recently, the auction on eBay sellers a 2007 MacBook with 3G antenna, caused a sought after Apple enthusiasts. In this patent, the antenna is hidden under some keyboard keys for improved receiving and transmitting efficiency. When the user does not click when a keyboard key, resonance of the antenna elements should be as far away from the metal conductor. Therefore in an ideal case, the antenna should be placed under the infrequently used keys, for example, key the screen shots.

According to the description of the Apple, an antenna can be placed under more key, the device will be based on the signal strength indicator, real-time judging which antenna under the key should be used. This patent did not point out that, under which antennas can be placed in the press, this could be a WiFi or Bluetooth antenna, mobile antenna may also be. Antenna to receive the wireless signals depends on the antenna configuration.

The industry expects future iMac will probably use this patent to improve performance when iMac to connect Bluetooth devices. MacBook keyboard may be integrated in WiFi or cell-phone antenna. In this way, MacBook users will not need to use the iPhone as a WiFi hotspot.

Apple officially launches Mac OS X Lion globally. Apple said the Lion has more than 250 new features, but also introduced new MacBook Air and the Mac mini, and a display interface used Thunderbolt.

According to Ars Technica reports, they found that by a firmware after the break, 2009 Mac Pro can be upgraded to the 2010 model performance. Upgraded camera can support two 6-core Westmere Xeon CPU, faster 1333MHz RAM, adding support for audio output to the Mini DisplayPort interface. These features only in the middle of 2010 models Apple will provide.

Hacker after development script, forced Mac Pro 4,1 models (2009 early paragraph) installed Apple for 2010 years Mac Pro publishing of firmware update, installed Hou, firmware report for Mac Pro 5,1 models (2010 medium-term paragraph), then is easy on can upgrade to faster of Westmere Xeon CPU, however, single nuclear CPU of models can used w series of CPU, and double nuclear CPU models requirements double nuclear QPI of CPU to normal run.

You can upgrade the CPU, so upgrading to faster 1333MHz RAM is naturally no problem. The new firmware also can let Mini DisplayPort HDMI to send audio signals.
Need to be reminded of is that Apple does not support this firmware upgrade, also does not support user replace the CPU, so to their own users to do a good expense of Apple Service ready for an upgrade.

It’s reported that Apple may use Mac App Store to release Mac OS X 10.7 Lion.

Of course Apple also provide DVD for those user who has no internet access. Apple promised that this year’s conference will showcase the Mac operating system’s “future.” Stores issued by applications that allows non-drive MacBook Air users to easily install the latest version of the system. Apple’s retail stores and even limit the number of software shelves, the hardware for the more profitable to make room. February this year, it was rumored that the company actually planned to stop all in-store retail boxed software.
