Looking for LM386 Bridge circuit using electret mic for input. Confused about signal ground and DC power ground, seems to be different symbols.

If the circuit is completely on one board, then the chassis ground and the earth ground can probably be connected.Looking for LM386 Bridge circuit using electret mic for input. Confused about signal ground and DC power ground, seems to be different symbols.
How can we comment on that without the circuit schematic you are referring to?Looking for LM386 Bridge circuit using electret mic for input. Confused about signal ground and DC power ground, seems to be different symbols.
A whetstone bridge is just one usage of the word "bridge" in electronics. See here for your introduction to bridged amplifiers - as AG says, the LM386 isn't a good amp for bridging.I am not sure what you mean by LM386 bridge circuit.
LM386 is meant to be used as an amplifier to drive a loudspeaker.
A bridge circuit is usually used to balance sensors as in a Wheatstone bridge.
