Some kind of LC sound resonator?

AI Thread Summary
A sound resonator in the hundreds of Hz range can potentially generate voltage, and various construction materials are being considered. Using a tube partially filled with water is one idea, as it can resonate at specific frequencies. Another suggestion involves utilizing a woofer speaker as a pickup or converter, especially when paired with a reflector to focus sound waves. The goal is to achieve frequency specificity rather than converting all sound into current. Exploring these options may lead to effective designs for sound-to-voltage conversion.

Hey all,

I'm trying to brainstorm a way to get a sound resonator (the order of hundreds of Hz) to create a voltage.

I'm not exactly sure what the resonator should be constructed of... any ideas?
 
Engineering news on Phys.org
Is it conceivable to use a tube-semi filled with water? I realize this will in fact resonate at a certain frequency, but could a voltage be obtained somehow?
 
You can also use a woofer speaker as a pickup/converter, especially if you construct a big reflector element to focus the sound down to the speaker face.
 
the reason why I'm considering something along the lines of a resonance tube, is because I want it frequency specific.. not just all sounds into a current...

know what i mean?
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
