发明名称 Internal personal computer loudspeaker pair
摘要 The PC loudspeaker pair are installed in the PC casing under consideration of the acoustic conditions in PC cases and with the aid of casing-specific installation bows. The loudspeakers are controlled via customary sound cards, either from an internal output of the sound card, if available, or from a cable through-put in a slotted cover plate A beeper provided in each casing is preferably replaced, i.e. the sound output of a main board are then exclusively output by the internal PC loudspeakers. The loudspeakers can include their own amplifier, that can be provided with current from the PC power supply.
