Playback System Operator Vibration for Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound playback technologies provide a poor operational feel for users as they can only perceive sounds aurally, lacking tactile feedback during playback manipulation.
Innovation Solution
A playback system that includes a processor, memory, sound outputter, and vibration imparter, where the sound outputter plays sounds in response to user operations and the vibration imparter vibrates in accordance with a vibration signal corresponding to the sound, allowing users to tactually sense the playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sound outputter plays sound in accordance with user operation, then the sound playback function is achieved, but the operational feel is poor because users can only perceive sound aurally without tactile feedback
Solution Approach 1:
The patent applies mechanical vibration by causing the operator to vibrate in synchronization with the playback sound. The vibration imparter generates vibrations that match the acoustic characteristics of the sound being played, allowing users to tactually perceive the sound through contact with the operator. This directly addresses the contradiction by adding tactile feedback to the audio playback experience, transforming the operator into a dual-sense output device that provides both auditory and tactile information.
2Ease of operation
If tactile feedback is added through vibration, then the operational feel is enhanced, but the device complexity increases due to adding vibration imparter components
Solution Approach 1:
The patent implements multi-functionality by designing the operator to serve dual purposes: it acts as both the control interface for sound playback and the vibration output device. The same physical component (the operator) that users manipulate to control playback also functions as the vibration imparter, eliminating the need for separate vibration motors or actuators. This approach enhances operational feel while minimizing the increase in device complexity by making one component perform multiple functions.
Solution Approach 2:
The patent merges the function of sound output and vibration output into a single integrated system. The operator that users touch and manipulate for playback control is combined with the vibration generation function, creating a unified device that provides both audio and haptic feedback through the same interface. This merging reduces system complexity compared to having separate audio output and vibration feedback mechanisms.

AI summary
A playback system includes a playback controller that causes a sound outputter to play a sound in accordance with an operation made by a user to an operator that is operated while the user is in contact with the operator; and a vibration imparter that vibrates the operator in accordance with a vibration signal that corresponds to the sound.
