Abstract
Official abstract text for this publication.
A noise reducing structure includes a first resonance tube that extends in a first direction, that takes in from a sound absorbing opening portion a sound wave that is generated from a noise source, and that causes the sound wave to resonate to reduce leakage to outside; and a second resonance tube that extends in a second direction differing from the first direction, and that, along with the first resonance tube, causes the sound wave that is generated from the noise source to resonate to reduce the leakage to the outside.
First claim
Opening claim text (preview).
What is claimed is: 1. A noise reducing structure comprising: a first resonance tube that extends in a first direction, that takes in from a sound absorbing opening portion a sound wave that is generated from a noise source, and that causes the sound wave to resonate to reduce leakage to outside; a second resonance tube that extends in a second direction differing from the first direction, and that, along with the first resonance tube, causes the sound wave that is generated from the noise source to resonate to reduce the leakage to the outside; and a third resonance tube that extends in a third direction differing from the first and second directions, and that, along with the first and second resonance tubes, causes the sound wave that is generated from the noise source to resonate to reduce the leakage to the outside, wherein the first and second resonance tubes are disposed on a substantially plate-shaped member, and the second and third resonance tubes are disposed with the substantially plate-shaped member interposed therebetween. 2. The noise reducing structure according to claim 1 , wherein the first and second resonance tubes are disposed so as to intersect each other. 3. The noise reducing structure according to claim 2 , wherein the first and second resonance tubes are disposed in a substantial L shape parallel to a plane along a vertical direction. 4. The noise reducing structure according to claim 1 , wherein the sound absorbing opening portion of the first resonance tube is disposed so as to face the noise source. 5. The noise reducing structure according to claim 4 , wherein a shape of the sound absorbing opening portion of the first resonance tube is substantially the same as a cross-sectional shape of the first resonance tube. 6. The noise reducing structure according to Claim 1 , wherein the second and third resonance tubes are connected to each other via an opening that is provided in the substantially plate-shaped member. 7. An image forming apparatus comprising: the noise reducing structure according to claim 1 , wherein the noise source is a driving device that drives an image forming unit.
