AI Thread Summary
Placing a small speaker in direct contact with a lithium-ion battery is generally not expected to cause negative effects like noise interference or unusual battery behavior. The primary concern is the potential for movement friction, which could wear through the battery's plastic covering. To mitigate this risk, options include using a thin Teflon strip between the two devices or securely gluing the speaker to the battery with hot glue. These methods can help prevent undesirable interactions while maintaining functionality. Overall, careful consideration of the physical contact is advisable.

Greetings, in a small project I'm doing, I need to have a small speaker literally touching the outside of a lithium-Ion battery. Will there be any negative results to these devices being in such close proximity? e.g. noise introduced into the speaker, or odd behavior induced upon the battery? If not, cool, but if so, what options do I have to prevent undesireable interaction?

Thanks

hi tetra

no not likely from the things you mentioned.
The only thing I would be worried about would be movement friction between the 2 items and that may wear through the plastic covering of the battery
2 possible ways to help avoid this would be
1) a thin layer of Teflon strip between the 2 items
2) gluing the speaker to the battery --- hot glue etc

Cool! Thanks Dave.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
