Resonators

1
Resonators

• Definition movement to an applied force
• Resonant frequency frequency where an object
  most efficiently oscillates.
• Role of mass and stiffness
• Sharply and broadly tuned resonator
• Wavelength and hemholtz resonators

2
Role of mass and stiffness

• Greater the mass the lower the resonant frequency
• Greater the stiffness the higher the resonant
  frequency

3
Sharply and broadly tuned resonators

• Sharply tuned
• Low rate of damping, more definitive tonal
  quality
• Broadly tuned
• High rate of damping, poor tonality

4
Hemholtz Resonators

• Greater the volume the lower the resonant
  frequency
• Greater the neck diameter the higher the resonant
  frequency

5
Wavelenth Resonator

• Greater the length the lower the resonant
  frequency
• 1/2 wavelength resonator
• 1/4 wavelength resonator

6
Wavelength Resonator

• 1/2 wavelength resonators resonate at whole
  number multiples of the primary resonant
  frequency. . e.g., 100, 200, 300, 400 Hz
• 1/4 wavelength resonators resonate at ODD
  multiples of the resonator frequency. e.g.,
  100, 300, 500, 700 Hz
