So I am a university student and my research is on the fabrication of a novel micro-speaker. I am a mechanical engineer, so my focus is mainly on the basic design and fabrication. Once I am able to make a working device, I need to do some analysis. Unfortuately, I have no technical background in audio engineering or acoustics or the like, but being at a university, I have access to good equipment; http://www.etymotic.com/pro/er7c.aspx is the microphone I currently have access to.
I am reading up on how to do some of this, but the major problem I have is that I cannot drive my speaker with a sinusoidal signal, and instead must drive it with a pulsed signal. I was wondering if anyone had any tips or good references on how I can perform a basic, but thorough, frequency analysis? As it stands, I am planning on just taking SPL measurements at small frequency intervals driven by a function generator, but I thought I would see if anyone had thoughts on this.
