Smartphone prototype loaded with sound

British researchers have developed a prototype of a new smartphone, which users will no longer have to worry about the battery being unloaded at the least expected moment. The device has a technology that allows its charging with street noise.

All smartphone users are well aware of the battery problem, which according to Murphy's law is always unloaded at the least expected moment, when we are far from home. Of course this is no longer a big deal, as we can always carry a portable energy bank with us, but a much more interesting solution to this problem has been developed by researchers from London's Queen Mary University.

The research team together with Nokia developed a prototype smartphone powered by sound. Device size Nokia Lumia 925 has special nanogenerators that produce energy from the noise, and to say from the vibration caused by the sound, turning them into electricity.

The technology comes from Korean scientists who presented her project four years ago, presenting the world a concept called "piezoelectric effect" describing an electric circuit made of zinc oxide nanopowire, which could be subjected to mechanical stress, thus compressed, stretched or curved. Koreans have discovered that nanoparticles are so sensitive that they can bend in response to sound pressure.

An electric generator was created that uses solutions developed by Korean scientists and installed in a smartphone prototype. Being exposed to loud noises, such as street noise, talking or music, is capable of producing a voltage of up to 5V, which is sufficient to charge the battery.

A budget smartphone for $ 60

Consumer smartphones are of the highest interest among consumers, and some manufacturers are focusing on satisfying the demand for such devices. Chinese company Lenovo is launching a low-priced model A1900, which will be available at a very attractive price of $ 60.

If you think that for this amount you will receive a product of no attention, you are seriously wrong. Chinese companies are known for cheap products that, despite appearances, are not so bad. The A1900 also looks quite interesting and although it does not appeal to a more demanding user, it will be a perfect tool for a person starting their smartphone adventure.

The smartphone is equipped with a 4.2GHz Spreadtrum SC7730 quad-core chip and is powered by a Mali-400 graphics unit. The amount of RAM is only 512 MB, but for devices with such a low price shelf this is not a surprise. The usable memory is 4 GB, but it can be expanded with a microSD card.

The image is presented on a 4-inch IPS-sized 800 x 400 pixel screen, with a 233 PPI denser screen. The phone also supports two slots for SIM cards and has GPS, WiFi and FM tuner. The network connects via tri-band 2G and 3G. It is powered by a 1500 mAh battery and the entire device only weighs 117 grams (its dimensions are 121 x 62 x 9.5 mm).

Further sources confirm the appearance of the Apple TV

Since the first rumor has surfaced on the Internet that Apple is gearing up to launch its own television, speculation about this device is increasing. Although the lack of specific information on it and even the least clear prototype photos, all claim that Apple TV will rise. Some even maintain that they have seen an operating Apple TV.

Trusted, but wanting to remain anonymous (as always), the Cult of Mac site reports that the new Apple TV looks like an overgrown monitor with a biting apple logo. He claims that the device is equipped with FaceTime iSight webcam that allows face-to-face conversations that can recognize the face of a user's face and focus on it, even if the person is moving around the room.

The software of the TV can be controlled using voice commands by Siri, an electronic assistant known from the latest iPhone. Transferring media from other Apple devices can be done wirelessly with the AirPlay technology used successfully in the Apple TV set-top box. It is almost certain that if the TV actually emerges, it will offer all the multimedia features the "box" that Apple currently has in its offer.
