Abstract

A speaker system for personal computers is disclosed. The speaker system has at least one speaker used for amplifying audio signals to predetermined levels and stereophonically dividing the amplified audio signals, and outputting sounds having an audio frequency. A power supply unit supplies electric power for the speaker while converting and rectifying an input AC voltage into a desired level of DC voltage. A speaker power switch is provided on the cabinet of the speaker for turning on or off the electric power for the speaker or for controlling output sound volume of the speaker. A drive fan is installed within the speaker and is rotated at a predetermined rpm when the speaker is turned on. This drive fan thus generates sucking force for forcibly sucking atmospheric air into the speaker. An anionizer is mounted on a printed circuit board within the speaker and generates anions from its anionizing plate, which consists of an anode plate and a cathode plate individually generating a high voltage. An anionizer power switch is provided on the speaker for turning on or off the anionizer. An air filter is installed around the drive fan within the speaker so as to filter off impurities from sucked atmospheric air.

Claims

1. A speaker system for personal computers, comprising:

at least one speaker amplifying audio signals, output from a personal computer, to predetermined levels and stereophonically dividing the amplified audio signals, and outputting sounds having an audio frequency;

a power supply unit used for supplying electric power for the speaker while converting and rectifying an input AC voltage into a desired level of DC voltage;

a speaker power switch provided on a cabinet of said speaker for turning on or off the electric power for the speaker so as to selectively activate the speaker or for controlling output sound volume of the speaker;

a drive fan provided within the speaker and rotated at a predetermined rpm when the speaker is turned on, said drive fan thus generating sucking force for forcibly sucking atmospheric air into the speaker; and

an air filter installed around said drive fan within the speaker so as to filter off impurities from the sucked atmospheric air.

2. The speaker system according to claim 1, further comprising:

an anionizer mounted on a printed circuit board within the speaker and adapted for generating anions from its anionizing plate, said anionizing plate consisting of an anode plate and a cathode plate individually generating a high voltage; and

an anionizer power switch provided on the cabinet of said speaker for turning on or off the anionizer so as to selectively generate the anions.

3. The speaker system according to claim 2, wherein said cathode plate of the anionizing plate is designed to absorb heat generated from an audio signal amplifying chip and to dissipate the heat to the surroundings, thus minimizing a resistance value of said audio signal amplifying chip caused by a heat dissipation from said chip and finally improving tone quality of the speakers.

4. The speaker system according to claim 2, wherein the cabinet of said speaker is provided with a power display for displaying an application of electric power for the speaker, an anionizer display for displaying an operational state of said anionizer, and a ventilation grille for allowing the atmospheric air to be sucked into the cabinet of the speaker by the suction force of the drive fan.

5. A speaker system for personal computers, comprising:

at least one speaker amplifying audio signals, output from a personal computer, to predetermined levels and stereophonically dividing the amplified audio signals, and outputting sounds having an audio frequency;

a power supply unit used for supplying electric power for the speaker while converting and rectifying an input AC voltage into a desired level of DC voltage;

a speaker power switch provided on said speaker for turning on or off the electric power for the speaker so as to selectively activate the speaker;

an anionizer mounted on a printed circuit board within the speaker and adapted for generating anions from its anionizing plate, said anionizing plate consisting of an anode plate and a cathode plate individually generating a high voltage;

an anionizer power switch provided on said speaker for turning on or off the anionizer so as to selectively generate the anions; and

a drive fan provided within the speaker and rotated at a predetermined rpm when the speaker is turned on, said drive fan thus generating sucking force for forcibly sucking atmospheric air into the speaker.
