Flat, transparent speakers get more efficient

Matsushita Electric Industrial Co. Ltd. has developed a pneumatically driven transparent flat-panel speaker which can be fitted over display screens. It consumes less power than directly driven transparent flat-panel speakers, making it suitable for mobile devices such as notebook PCs, cell phones and PDAs (personal digital assistants), the company announced last week.

The Sound Window consists of a transparent panel mounted in front of the display, and a separate driver to vibrate the air between the panel and the display to create sound, according to a statement by the Osaka-based company, better known for its Panasonic brand name.

Because the speaker panel is so thin and flexible, sound quality is unaffected even if the display panel is touched, so it can even be used with touch-screen displays, the statement said.

The system can send sound pressure to the entire speaker panel surface, allowing the speaker panel to be formed in any shape and the driver to be installed anywhere, the statement said.

A small driver diaphragm can efficiently vibrate a panel ten or more times larger, Matsushita said.

The company plans to commercialize the Sound Window later this year, it said.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

The Brother MFC-L8900CDW is an absolute stand out. I struggle to fault it.

MSI GT75 TITAN

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

If you’re looking to invest in your next work horse laptop for work or home use, you can’t go wrong with the MSI GE63.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
