Sound Effect Emission System with Displacement Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound effect emission systems fail to provide a realistic and enhanced user experience, particularly when a first element moves relative to a second element, as they often produce faint or unnatural sounds, and existing solutions for vehicles or objects like doors lack effectiveness in rendering natural sounds, leading to inadequate warning or experiential enhancement.
Innovation Solution
A system comprising a sound effect emitting unit, a displacement sensor, and a calculator that adjusts the playback of stored sound effects in real-time based on the amplitude of movement, allowing for a natural and adaptive sound experience by correlating sound effects with the movement's progression and amplitude, with options for users to choose between natural and synthetic sounds.

1Ease of operation
If a sound effect emission system is added to increase user perception of sound effects, then the user's experiential moment is enhanced, but the sound effects become synthetic and less realistic
Solution Approach 1:
The system dynamically adjusts sound effect parameters based on the actual movement characteristics of the first element relative to the second element. The calculator computes movement parameters (amplitude, velocity, acceleration) and the sound effect emitter adjusts sound characteristics in real-time to match these dynamics, making the synthetic sound effects become adaptive and context-aware rather than static and predetermined
Solution Approach 2:
The system changes multiple sound parameters simultaneously including frequency, amplitude, duration, and timing based on the detected movement parameters. By adjusting these parameters dynamically according to the actual movement characteristics, the system transforms fixed synthetic sound effects into variable sound effects that adapt to real-world conditions, improving realism while maintaining the enhanced perception benefit
2Loss of information
If a continuous warning sound effect is used to alert pedestrians, then the warning is clear and audible, but the sound becomes unpleasant for drivers and pedestrians
Solution Approach 1:
Instead of continuous sound emission, the system uses periodic sound effects that are triggered only during specific movement phases. The sound effect emitter activates sound effects at discrete moments when the first element is in particular positions or moving at specific speeds, creating an intermittent warning pattern that conveys information while being less intrusive and unpleasant than continuous sounds
Solution Approach 2:
The system adjusts the timing, duration, and intensity of warning sound effects based on the dynamic movement characteristics. When the first element moves quickly or enters critical zones, the sound effects are triggered with appropriate timing and intensity, while during slower or non-critical movements, the sound effects are reduced or omitted, creating a dynamic warning system that adapts to current conditions and reduces unpleasantness
3Ease of operation
If a synthetic engine sound effect is added to enhance sportiness sensation, then the driver's sensation of sportiness is improved, but the sound effect is perceived as a gimmick rather than realistic
Solution Approach 1:
The system dynamically adjusts sound parameters (frequency, amplitude, harmonics, timing) based on actual vehicle movement parameters such as acceleration, velocity, and engine load. By continuously adapting these parameters to match real vehicle behavior, the system transforms the synthetic sound effect from a static gimmick into a dynamic representation that closely follows actual engine characteristics, improving realism while preserving the enhanced sportiness sensation
Solution Approach 2:
The system uses feedback from movement sensors and vehicle parameters to continuously adjust the sound effect emission. The calculator monitors actual movement and the sound effect emitter adjusts its output based on this feedback, creating a closed-loop system where the sound effects adapt to real-time conditions. This feedback mechanism ensures the sound effects remain realistic and context-appropriate rather than being fixed synthetic sounds perceived as gimmicks
