loudspeaker
Let an agent explain loudspeakers and how they work, relay driver types, enclosures, specifications and history from audio engineering sources, describe uses from hi-fi to public address, and distinguish loudspeakers from headphones, amplifiers, microphones and complete audio products.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain loudspeakers and how they work, relay driver types, enclosures, specifications and history from audio engineering sources, describe uses from hi-fi to public address, and distinguish loudspeakers from headphones, amplifiers, microphones and complete audio products.
An electroacoustic transducer that converts an electrical audio signal into sound, typically a cone driven by a voice coil in a magnetic field mounted in an enclosure, in forms from hi-fi and studio speakers, public address loudspeakers and guitar amplifier speakers to consumer products such as the iPod Hi-Fi, educational kits such as the Kano Speaker Kit, art installations such as the Poetry Jukebox and active subwoofers; loudspeakers are characterised by frequency response, sensitivity, impedance and directivity.
What it is for: Reproducing sound from electrical signals.
It can be explain working and types; relay specifications and history; describe uses; distinguish related devices.
Distinguishing features
Electroacoustic transducer
Driver and enclosure
Many formats
Measured performance
What it looks like
A box or cabinet with one or more cone or dome drivers.
Physical character
moving-coil driver patented: 1925 year - Rice and Kellogg
typical impedance: 4 or 8 ohms
typical sensitivity: about 85-95 dB at 1 W 1 m
How it is recognised
Electrical signal to sound transducer
Hi-fi speakers, PA loudspeakers, guitar amplifier speakers, iPod Hi-Fi, Kano Speaker Kit, Poetry Jukebox, subwoofers
Headphones sit on the ears; amplifiers drive speakers; microphones convert sound to signal

- How should audio engineering sources be linked?
- The registry entry has merged aliases naming products, a kit and an art installation; should they be split off?
