project是做 guitar amp 估计都是重点在做音箱吧
Week 1
Lesson 1: Introduction to wave propagation, simple oscillating systems,
sound pressure, sound waves, the speed of sound, wavelength, frequency and
wavenumber, sound pressure level, and auditory directional cues.
Lesson 2: Electronics fundamentals - charge, current, voltage, resistance,
Ohm’s law, DC circuits, finding currents and voltages in simple circuits
Week 2
Lesson 1: Reflection and absorption of sound, resonances in air columns,
resonances in enclosures and rooms, diffraction of sound, reverberation.
Lesson 2: Power, impedance matching, operational amplifiers, voltage buffer,
inverting amplifier
Week 3
Lesson 1: Mathematical fundamentals for AC circuit analysis, phasors
Lesson 2: AC signals, capacitors, inductors, impedance, AC circuits and AC
circuit analysis, simple filters (high-pass, low-pass, band-pass)
Week 4
Lesson 1: Electric guitar electronics, pickup design, volume control
circuits, tone control circuits, pickup placement, frequency content and
tone, wah pedal, talk box
Lesson 2: Converting electrical signals to sound – loudspeakers.
Week 5
Lesson 1: Designing speaker enclosures, basic principles, interaction of
speaker driver with the cabinet, why a cabinet at all? Closed-box speaker
design.
Lesson 2: The ported / bass reflex speaker design.
Week 6
Lesson 1: Overview of a simple guitar amplifier, preamp, volume control,
tone control, gain and distortion, tube circuit distortion, power amp
section.
Lesson 2: Building the guitar amplifier, how to solder, getting the amp to
work - systematic testing and troubleshooting. |
