ANSI/IEEE Combined loudspeaker and microphone form
IEEE-library form of combined loudspeaker and microphone: this representation identifies an electroacoustic device serving loudspeaker and microphone roles.
In plain English
What does ANSI/IEEE Combined loudspeaker and microphone form mean?
This reference locates combined loudspeaker and microphone in Autodesk's IEEE-oriented annunciations family. This representation identifies an electroacoustic device serving loudspeaker and microphone roles. The public library uses HAN1B8 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Use the surrounding circuit labels and the project legend to identify the intended operating condition and connection. Carry the same device reference into the schedule or equipment document so the symbol can be reconciled with its real terminals, function and operating limits.
What the drawings help you do
Show transmit/receive connections and the documented operating modes. Two acoustic roles do not imply simultaneous two-way operation. Show transmit/receive connections and the documented operating modes. Two acoustic roles do not imply simultaneous two-way operation. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

How to read it
- Show transmit/receive connections and the documented operating modes.
- Two acoustic roles do not imply simultaneous two-way operation.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Show transmit/receive connections and the documented operating modes.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
Two acoustic roles do not imply simultaneous two-way operation.
