Abstract (en)
[origin: EP1122974A1] The loudspeaker has a sound radiating element (4d) mounted in a holder with an associated converter (6) that converts the audio signals fed to it into mechanical vibrations to stimulate the sound radiating element to transversal flexural vibrations and hence sound radiation. The flat loudspeaker thus formed is integrated into a lighting arrangement. The converter is mounted in a light housing and forms part of the light as well as the sound radiating element.
