Hand-held Apparatus Speaker Vibration Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held information processing devices lack the ability to provide a high sense of immersion through localized sound and vibration, which limits the user's engagement and feedback during applications like games.
Innovation Solution
A hand-held information processing apparatus with two speakers and a vibrator, where the vibrator is arranged between or overlapping the speakers, and operates according to an arbitrary input waveform, allowing for synchronized sound and vibration feedback that localizes the experience, enhancing immersion by presenting application progress through sound and tactile cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vibrator is added to provide vibration feedback, then the sense of immersion is improved, but the device complexity increases
Solution Approach 1:
The vibrator is integrated into the housing structure and positioned between the two speakers, merging multiple components (vibrator, speakers) into a unified assembly. This combination allows vibration feedback and sound output to work together synergistically, enhancing immersion while managing device complexity through integrated design
Solution Approach 2:
The patent adds a tactile dimension to the user experience by introducing vibration feedback alongside auditory output. This multi-sensory approach (adding tactile dimension to auditory experience) enhances immersion by engaging multiple senses simultaneously, transforming the interaction from purely visual/audio to include tactile feedback
2Measurement precision
If the vibrator is positioned between the speakers, then vibration localization is improved, but the available space for component arrangement is reduced
Solution Approach 1:
The vibrator is positioned specifically between the two speakers, creating localized vibration feedback at the center of the device. This strategic placement ensures that vibration is delivered precisely where it can be most effectively perceived by the user's hands, optimizing localization without requiring additional space beyond the speaker arrangement
Solution Approach 2:
The vibrator is nested within the housing structure in the space between the speakers, utilizing the existing component layout to accommodate the vibration mechanism. This nested arrangement allows the vibrator to be integrated into the available space rather than requiring additional external space
3Force
If speakers are arranged at the left and right end portions, then sound vibration transfer to user is improved, but the localization of vibration by vibrator becomes difficult
Solution Approach 1:
The patent combines the functions of the speakers (for sound output and vibration transfer) with the vibrator (for localized tactile feedback). By positioning the vibrator between the speakers and coordinating their operation, the system merges auditory and tactile feedback mechanisms to achieve both vibration transfer and localization simultaneously

AI summary
A non-limiting example information processing apparatus comprises a housing, and a left speaker and a right speaker are provided in a left end portion and a right portion of the housing and in an inside of this housing. Each speaker is arranged such that a vibration direction of a diaphragm becomes in a direction perpendicular to a plane surface of a display panel that is provided in the front of the housing. Sound emission portions for emitting sounds from the speakers are formed in both end portions of the housing and on a side surface at near side or this side that the speakers are arranged. Therefore, sounds are emitted toward a side of a player who holds the information processing apparatus. A vibrator that is provided between the two speakers is driven simultaneously with the speakers or in a predetermined order.
