Cellphone screen to act as a speaker

The UK based company, NXT Sound has announced significant progress in SoundVu technology applications with announcements from NEC’s subsidiary, Authentic, the developer of the world’s first SoundVu LCD monitor. Authentic announced the successful application of SoundVu technology to ultra-thin, small applications that have LCD screens, such as mobile telephones, mobile game equipment and PDAs.

A demonstration has been held this week, from NXT licensee Authentic, which featured two SoundVu technology enabled demonstrators, developed for undisclosed customers; a PDA sized product and a mobile phone sized product both of which use a piezo-electric Distributed Mode Actuator to turn their screens into speakers.

Significantly, this smaller sized application of SoundVu technology meets GSM and 3G mobile phone specifications and standards.

Because of its larger radiating area and unique mode of operation, a SoundVu panel outperforms a conventional mobile phone receiver in three key respects. It provides superior sound quality, particularly in wideband hands-free mode; it ensures broad radiation of all audio frequencies (no treble beaming); and it eliminates the need for precise coupling to the ear in receiver mode. Because a conventional speaker module is no longer required, SoundVu technology also opens up exciting new product design possibilities.

The break-through is particularly good news for mobile phone users who need to see the screen of their mobile while listening to it.  As 3G applications, such as video telephony become more widespread and higher quality streaming music and video is being distributed, mobile telephone speakers need to be able to emit high-quality sound production.

“The progress being made with SoundVu technology by our licensees is very pleasing.  NXT attended both launches this week, and we’re pleased to say the reactions to the demonstrators has been very positive,” NXT’s CEO, David Pearson said.

While the company didn't name the customers for the SoundVu speaker/screen, last March Siemens did say that it was working with NXT on a screen incorporating a speaker. The company showed off a Siemens C45 handset that had been modified to use the SoundVu technology. NXT has also licensed its technology to several other cellphone companies, Ericsson, LG Electronics, Matsushita, NEC and Philips.
