Concept of Q of Loudspeakers

acenengineers.com

In practice, a speaker is not used in isolation. It is enclosed in a cabinet to avoid back and front cancellation of air compression as the cone moves back and forth. ‘Air’ itself is a compressible medium and as the cone moves, the air inside the enclosure also contributes in storing energy. Thus when the speaker is mounted in a cabinet there is an additional ‘compliance’ of the air in the cabinet. Technically, the driver and cabinet compliances appear as a series circuit in electrical equivalence. If the volume of the cabinet is very large, there will be very small effect on the cone movement but if the volume is small then the air will get compressed (high stiffness) and affect the speaker behavior. A large air volume has a large compliance while small air volume has a small compliance. How electrical damping works: A speaker consist of a magnet and a coil forming a dynamo like structure. If the cone moves it produces a voltage at the speaker terminals. If this voltage is short circuited by a low resistance- like the source resistance of the driving amplifier- the cone movement is resisted by a back e.m.f.

What is Speaker Q? (Qts, Qes, Qms Explained) | Loudspeaker & Acoustic ...

engineeryoursound.com

Q stands for "quality factor" in a speaker. It is a term used by speaker designers to define how well damped a speaker is, however it is not an actual measure of damping. Q is the inverse of the damping ratio. In very simple terms, a low Q means more damping, which results in greater performance control. In the world of speaker design and speaker impedance curves, Total Q or Qts describes the sharpness of the speaker’s resonance. Speakers vibrate to make sound. With these large vibrations comes resonance. All vibrating objects, including speakers, have a resonant frequency. For example, knowing the speaker’s resonant frequency in advance will allow you to prevent a cabinet from ringing. But what has speaker resonant frequency got to do with speaker Q?
