Create a creative and technical emoji that represents sound design. The design should feature a soundwave, a pair of studio headphones, and an audio synthesizer or soundboard to symbolize the manipulation and creation of unique soundscapes. Add subtle elements like audio cables, a mixing console, or a waveform to reflect the technical aspect of sound design. Use vibrant, futuristic colors like neon blue, purple, and green to represent innovation and creativity in sound. The background should be transparent. emoji
