<p>In a loudspeaker (1) according to the present invention, a functional, modified or separate plane-like part or other component of a product meant for sound reproduction, i.e., a diaphragm (3) of the body structure (2) of said loudspeaker vibrates mechanically at the frequency of the reproduced sound, controlled by a voice coil (5) of a driver (4). Depending on the elasticity characteristics of the diaphragm, sufficient amplitude of movement for sound reproduction is achieved by means of a stiff, thin diaphragm (3) that vibrates in the same phase as the voice coil. The sound beam of the loudspeaker is wide and it is a point-like source of sound. The depth of the loudspeaker casing is small and it takes up little space, so it can be built as a part of another product or structure, such as a door, shelf, wall, cabinet or other piece of furniture, and it can be sold as an integrated part therein. The loudspeaker also provides immense freedom to architects and other designers of furniture, structures and spaces, as it can be covered, painted or hidden from view.</p> |
