Is this a microphone? If so give me some helpful links to learn something about it. I have to draw this element and make a pattern for it. So links for pattern would be also great. The whole scheme looks like this:
Looks like a motor controller circuit.
Uynp1 and Uynp2 are two H-Bridge controls for direction and stop and the rest of the circuit is a interesting dead time or perhaps a dynamic breaking mode control.
The line under the M is likely an inhouse differentiator. With an AC motor it might have a ~ (tilde) character under the M instead of the - (dash) for DC motor.
