Tuning: Why do some notes not sound right?
Tuning: Why do some notes not sound right?
Depending on the resonator you attach the resonant frequencies of the actuator can change. Sometimes, especially for lower frequencies the resonance can be too much and cause the actuator to shake too wildly, we solve this by dampening the actuator.
There Are 3 Methods Of Tuning:
There Are 3 Methods Of Tuning:
Software Tuning
Software Tuning
Use the provided function in the Arduino IDE library to tune specfic frequencies by dampening the actuator.
This method is recommended and very easy. The advantage is being able to target just the problematic frequencies without effecting the others.
Magnetic Tuning
Magnetic Tuning
Use a permanent magnet to physically tune the actuator
This method is recommended as a second option, and is an invaluable tool to educators and learners who want to experience the resonance changing with the magnet's placement.
Soft Membrane Tuning
Soft Membrane Tuning
Place a soft membrane (paper towel, napkin) at the top to dampen the actuator
This is not generally recommended except for those looking to learn and experiment, as a practical matter the other two methods will usually create better sound.
