<p><P>PROBLEM TO BE SOLVED: To provide an ultrasonic generator of an electronic apparatus wherein air which flows-in from an inlet port and flows into an air cooling duct is rectified, and blast efficiency is increased, so that cooling efficiency is improved, and to provide a silencer which can be installed without taking place. <P>SOLUTION: The ultrasonic generator is installed on an electronic apparatus which has the air cooling duct in which a blast mechanism is arranged which blasts air between the inlet port and an output port of air in order to perform air cooling of an air cooling object like a CPU socket. The ultrasonic generator is provided with a blast detection means which detects blast level in a blast rectifier, regarding blast generated in the cabinet of the electronic apparatus; an ultrasonic generating means which generates ultrasonic wave based on the blast level of the blast rectifier which is detected by the blast detection means; and an operation processing means which judges whether output from the blast detection means exceeds predetermined threshold, generates a sound signal for generating ultrasonic wave corresponding to the blast level in the blast rectify part when the output exceeds the threshold, and performs drive direction of ultrasonic irradiation to the ultrasonic generating means. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
