Electronic Tempo Trainer Phase Comparator Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metronomes cannot visually display the time-difference between the beat set by the device and the attack from a musical instrument, making it difficult for musicians to determine if they are playing ahead of or behind the beat, which is essential for developing a sense of timing.
Innovation Solution
An electronic tempo trainer that uses a phase comparator to detect the difference in phase between the metronome signal and the instrument's attack, displaying this difference using lights or a spinning disk with a strobe light, allowing musicians to visually understand their timing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional metronome is used, then the beat is steady and mathematically perfect, but the musician cannot visually determine if they are playing ahead of or behind the beat
Solution Approach 1:
The patent implements a visual feedback mechanism using a display that shows the difference between the metronome beat and the musician's attack. The display presents numerical or graphical information indicating whether the musician is playing ahead of, on, or behind the beat, providing real-time feedback that helps them improve timing accuracy.
Solution Approach 2:
The patent introduces an intermediary display device that translates the temporal relationship between the metronome signal and the musician's attack into visual information. This intermediary visual representation bridges the gap between the auditory metronome beat and the musician's perception of their own timing.
2Measurement precision
If electronic metronomes with quartz crystals are used, then the beat accuracy is improved, but the device still cannot visually display the time-difference between beat and attack
Solution Approach 1:
The patent merges the metronome function with a visual display function into a single integrated device. The display component is combined with the metronome circuitry to simultaneously provide accurate beatkeeping and visual timing feedback, eliminating the need for separate devices.
Solution Approach 2:
The patent creates a multi-functional device that serves both as an accurate metronome for beatkeeping and as a visual feedback tool for timing training. The single device performs multiple functions: generating the metronome beat, detecting the musician's attack, calculating the time difference, and displaying the result visually.
3Stability of the object's composition
If musicians practice with traditional metronomes, then they can maintain steady tempo, but they cannot develop an ear for the beat without visual assistance
Solution Approach 1:
The patent provides visual feedback that directly helps musicians develop their ear for the beat. By seeing the real-time display of their timing relative to the beat, musicians can immediately adjust their playing and internalize the correct timing relationship more effectively than with auditory feedback alone.

AI summary
A tempo trainer includes a plurality of lights displayed on a front display surface of a housing in the form of at least one of a line or a circle and including a center light. A beat can be set for an electronic metronome. An attack from a musical instrument can be compared with the beat using a phase comparator. The difference in phase between the beat and the attack can be determined by the phase comparator. The difference in phase (time-difference) between a beat of an electronic metronome and an attack of a musical instrument can be displayed by the plurality of lights. The plurality of lights can visually display the difference with at least one or a portion of the plurality of lights becoming lit either ahead of, at, or after a center light to indicate whether a musician operating the musical instrument is playing ahead of, at, or after the beat of the electronic metronone.
