Latest invention In Sound : Flat Flexible Speakers that Produce a Clear Sound

 A loudspeaker, which is less than 0.25mm thick, is the latest invention in technologypresented by engineers from University of Warwick. The device is flexible and can be easily hung up a wall in an apartment or, due to its specific technique of producing sound, it can be used as a way of making clear public announcements in different places, such as, for example passenger terminals. Besides being extremely lightweight, this latest technological invention does not require huge investments. Slim and flexible, such speakers can be installed in ceiling tiles or inside vehicles.

Warwick Audio Technologies, is a spin-out company that says its device generates planar directional sound waves in public places. These waves project further than sound produced by usual speakers. Engineers dubbed their latest invention Flat, Flexible Loudspeaker (FFL). According to the company's CEO, Steve Couchman, the revolutionary speaker could completely replace the conventional speakers that are nowadays used in homes, cars and public places such as passenger terminals and shopping centers.

"Audio visual companies are investigating its use as point of sale posters for smart audio messaging and car manufacturers are particularly interested in it for its light weight and thinness," he said.
The flexible speaker works by transforming an electric signal into sound. In conventional speakers the signal is used to produce a varying magnetic field that vibrates a mechanical cone, thus making the sound. However, the technology behind the flexible speaker connects thin, conducting and insulating, materials that create a flexible laminate. When an electrical signal excites the laminate, it vibrates, so generating sound.

Group Violin recording conducted in Sound Engineering Academy, Campus

It was unforgettable yet fascinating event for the Sound Engineering Academy in Trivandrum which showcased the great composition of legendary violinist Chidambaranath. The event was a thrilling occasion for all the music lovers, students and officials of Sound Engineering Academy

In the live recording of this violin play about 15 violinists joined the recording. The Senior Violinist Mr Chithambaram does the orchestration & Conduction. Recording take place at SEA – Studio. Yamaha 02R Digital  Audio Console was used and ProTools 8.4 Was used as Digital Audio Workstation. Condenser microphones of AKG, Shure & Audio-Technica  were used.

The microphone placement was challenging. All the calibrations were done properly and executed a successful Recording. The Recorded Tracks Sounds Amazing. The percussion & Vocal Sessions to be completed.
