Drum Sound Pickup Device Signal Mixing and Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound pickup devices restrict variations of musical sound generation by only outputting performance sounds detected by sound pickup sensors, failing to incorporate and mix other environmental sounds effectively.
Innovation Solution
A sound pickup device with a clamp part for fastening a drum hoop, featuring a first output means for detecting striking surface vibrations, a second output means for picking up performance sounds, a third output means for mixing signals, and a selection means to output either or both signals, along with a housing part for a battery, allowing for increased sound variation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only the performance sound picked up by the sound pickup sensor is outputted to the outside, then the signal based on the detection can be controlled to be outputted, but the variations of musical sound generation are restricted
Solution Approach 1:
The output signal is divided into three distinct segments: musical sound signal (synthesized), performance sound signal (microphone pickup), and mixed signal combining both. This segmentation allows independent control and selection of different signal types, enabling diverse musical sound variations without overwhelming complexity.
Solution Approach 2:
The system dynamically switches between different output modes (musical sound only, performance sound only, or mixed) based on operational needs. The ability to change output configurations in real-time increases versatility while maintaining manageable device complexity through structured control options.
2Adaptability or versatility
If the sound pickup sensor detects sound from the surroundings of the drum, then environmental sounds can be captured, but unwanted signals may be outputted
Solution Approach 1:
The system uses an intermediary mixing process that combines musical sound signals with performance sound signals. This mixing acts as a mediator that can selectively integrate desired environmental sounds while filtering out unwanted signals through controlled signal combination and processing.
Solution Approach 2:
The system incorporates feedback mechanisms where the detected performance sound is processed and integrated with synthesized musical sounds. This feedback loop allows the system to monitor and control what signals are outputted, enabling selective capture of environmental sounds while suppressing unwanted signals through active signal management.
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
The device enhances musical sound generation by mixing and outputting musical and performance sound signals, offering increased versatility and sound capture capabilities.
Implementation Method 1
a first output means detecting vibration of a striking surface of the drum, generating a musical sound signal based on the detected vibration
Implementation Method 2
a second output means detecting a performance sound generated by the vibration of the striking surface, generating a sound pickup signal based on the detected performance sound
