Speaker Positioning in Image Forming Apparatus Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face challenges in ensuring clear audibility of sound emitted by the speaker, as the sound is often obstructed by the ejected paper or not resonated effectively within the device's internal space.
Innovation Solution
The speaker section is strategically positioned closer to the user within the housing, adjacent to the in-body space, allowing sound to resonate clearly and be audible without obstruction from ejected paper, with the speaker accommodated in a location that optimizes sound emission and minimizes vibration and reverberation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker is disposed within the joint housing facing the in-body space, then sound resonance is enhanced and audibility is improved, but the speaker may be obstructed by ejected paper
Solution Approach 1:
The housing interior is divided into distinct functional zones: the in-body space for paper ejection and the speaker accommodation area. By segmenting the space, the speaker can be positioned to resonate within the housing while the paper ejection path is separated, preventing obstruction of the speaker by ejected paper.
Solution Approach 2:
The speaker is positioned in a different spatial dimension relative to the paper ejection path. The speaker faces the in-body space for resonance but is located such that paper ejection does not directly obstruct the speaker, utilizing three-dimensional spatial arrangement to resolve the obstruction issue.
2Reliability
If the speaker is positioned closer to the user within the housing, then sound clarity and audibility are improved, but the speaker location must be optimized to avoid vibration and reverberation interference
Solution Approach 1:
Different regions of the housing interior are assigned different acoustic characteristics. The speaker is positioned in a location that provides good sound clarity for the user while being acoustically isolated from vibration sources and reverberation-prone areas, creating localized optimal conditions for sound emission.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration ensures that sound emitted by the speaker is clearly audible to the user, even when paper is being ejected, by positioning the speaker to resonate within the in-body space and reducing interference from paper ejection, enhancing user interaction and notification during operations like fax communication.
Implementation Method 1
sound emitted by the speaker is resonated in the in-body space so that the sound emitted by the speaker is clearly audible to the user

AI summary
An image forming apparatus includes an image forming section, a casing, a housing, an operation panel, and a speaker section. The image forming section forms an image on a sheet of paper. The casing accommodates the image forming section. The housing is supported on an upper surface of the casing. The operation section is operated by a user. The speaker section provides sound information to surroundings. The housing has one side on which the user operates the operation panel and another side opposite to the one side. The speaker section is accommodated at a location closer to the one side than the rear in an interior of the housing.
