<P>PROBLEM TO BE SOLVED: To add a capability to reduce the volume of harsh noise to a handheld handy cleaner without impairment of a dust suction capability thereof to fit the size of the compact handheld cleaner. <P>SOLUTION: A housing 20 is formed by combining a left side half housing 21 and a right side half housing 22, which are each half of a molded product. The housing 20 is configured to be formed with a resonant chamber 400 through the combination of the left side half housing 21 and the right side half housing 22, and a resonator 40 can be formed concurrently with the formation of the housing 20. The resonator 40 has a capability to reduce sound produced by a blower mechanism 30, and can prevent a decline in the dust suction capability without the need of installing a ventilation sponge for sound insulation to an exhaust port 28 and to reduce the volume of harsh noise while fitting the size of the compact handheld cleaner. <P>COPYRIGHT: (C)2012,JPO&INPIT |
