natural resonance: Process in loudspeaker technology and room acoustics is important. Natural resonance is a molecularly determined resonance behavior of a material. Almost any material will resonate at one or more specific frequencies when struck or subjected to some other external force. The specific natural resonance frequency depends on the shape, weight and stiffness of the material.
With loudspeakers there are intentional and unintentional - unavoidable - system resonances, such as e.g. B. the natural resonance of the moving mass of the speaker. Other resonances, such as B. those in the housing of the speaker, in the material of Membran or on the suspension of the Chassis are unwanted and should be avoided as far as possible in terms of design.
A featherweight membrane (see membrane) is electrically charged and placed between two electrodes to which the high-voltage music signal is applied. Because the film is driven uniformly over the entire surface, it is free from
partial vibration problems.
