Flexible Speakers :

• A loudspeaker, which is less than 0.25mm thick, is the latest invention in technology presented by engineers from University of Warwick. 

• The device is flexible and can be easily hung up a wall in an apartment.

• 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 passenger terminals.

• 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 these flexible speakers connects thin, conducting and insulating, materials that create a flexible laminate. When an electrical signal excites the laminate, it vibrates, so generating sound.
