Abstract
The invention relates to a monitor comprising a picture tube and an audio part mounted on a base. The picture tube unit (,) of the monitor includes main sound reproduction elements (,) for the production of sound frequencies deviating from the self-resonant frequency. The base (,) comprises a bass unit which is used to reproduce sound frequencies at the self-resonant frequency. Thus, it is possible to dampen the vibration caused by the self resonant frequencies so that these frequencies do not harmfully interfere with the picture display. The invention is applicable especially in connection with a picture tube operating have a fine pitch shadow mask.
