Portable speech and music teaching unit visually displays speech, song or tones as resonance patterns in fluids or solids using a variable frequency and amplitude tone generator

摘要

The portable speech and music teaching unit displays speech, song or tones as resonance patterns in fluids or solids using a variable frequency (8) and amplitude (7) tone generator (F) with mixing with an external signal source (9) and conversion (3) to a sound coupled to the resonance medium (4) in a bounded surface (2).
