    • The invention relates to a monitor comprising a picture tube and an audio part mounted on a base. The picture tube unit (1) of the monitor includes main sound reproduction elements (6, 7) for the production of sound frequencies deviating from the self-resonant frequency. The base (2) 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.
    • 本发明涉及包括显像管和安装在基座上的音频部分的监视器。 监视器的显像管单元(1)包括用于产生偏离自谐振频率的声音频率的主声音再现元件(6,7)。 基座(2)包括用于在自谐振频率下再现声频的低音单元。 因此,可以抑制由自谐振频率引起的振动,使得这些频率不会有害地干扰图像显示。 本发明特别适用于具有细间距荫罩的显像管。
