First Experiments

Tried some experiments today with low frequencies and 2 speakers. I used cheap speakers and PD to simulate a low frequency environment, to see how the speakers respond. This is important if I am to use speakers as tactile transducers. Here are some observations:

  • The diameter of the speaker needs to be quite large, so that the force of the low frequency can be translated effectively.
  • The speaker of about 2 inches in diameter can respond to 50 Hz, so based on the above observation, a  larger diameter should have a better respond at about 20Hz or slightly less.
  • Using small speakers would be out of the question, as they seem more responsive to slightly higher frequencies, usually above 100Hz.
  • Cheap speakers can’t be used 🙂
