Which symbol denotes a microphone in circuit design?

In circuit design, the symbol representing a microphone is specifically designed to depict its function and characteristics. A microphone converts sound waves into electrical signals, and its symbol reflects this capability. The design typically resembles a simple microphone shape or may include annotation indicating its role in the circuit.

Understanding the representation of various components in circuit diagrams is crucial, as it allows for clear communication of how different elements interact. The symbols for an electric bell, loudspeaker, and motor are distinctly different and represent their own respective functions, which do not correspond to the operation of a microphone. Thus, recognizing the correct symbol for a microphone aids in accurately interpreting and designing electronic circuits involving audio input devices.
