A to Z of Loudspeakers

Have you ever thought about what is inside a speaker? A speaker is composed of multiple components that when combined provide sound. In this A to Z list, I will explain some of the more important and interesting components in a speaker. This way, you can become more familiar with them and understand better their structure and how they operate.

Audio: Although not a component, this is the product of the speaker components working together.

Basket: The cage that holds a speaker driver together.

Cone: The material that actually pushes the air back and forward to create the sounds we hear in a speaker driver.

Dust Cup: a cover over the centre of the speaker driver which prevents dust and other materials from entering into the rear of the speaker driver.

Electronics: having or operating with components such as microchips and transistors that control and direct electric currents.

Former: The tube around which the voice-coil is wrapped.

Gasket: Material used to seal the basket to the enclosure.

High Frequency: The pitch of a note is measured by it's frequency - high frequency means a high pitched note.

Inductor: An electronic component used in the crossover, which is used to send the high frequencies to the tweeter, and low frequencies to the woofer.

Jack socket: Used for inputs and outputs in some audio equipment - most commonly recognised as a 'headphone socket'.

Kilobytes: A unit of memory or data equal to 1,024 bytes.

Lead Wires: The wires used to connect a speaker driver to the amplifier.

Magnet: Used in the loudspeaker to give the voice-coil a magnetic field to push and pull against when the signal is fed into it, turning electricity into movement, and movement into sound.

NFC: short for Near Field Communication, a wireless communication technology used for mobile payments, but in speakers used for quick and simple pairing of Bluetooth connections.

Output: It is the power, energy, or other results supplied by a device or system.

Port: The tube or slot in a speaker that is used to provide a balancing pressure for the main speaker driver to push and pull against - the port size is matched or tuned to the amount of air that the speaker driver can move.

Quality: General excellence of standard or level

Ring: The cover on a loudspeaker that hides the screws mounting the driver to the enclosure.

Surround: The flexible material securing the cone to the basket.

Tweeter: A small speaker driver capable of producing high frequencies or high pitched notes.

USB: Universal Serial Bus, a standardized technology for attaching peripheral devices to a device.

Voice coil: The coil of wire that translates the electrical signal into movement in the speaker driver, by pushing and pulling against a fixed magnet.

Woofer: A large speaker driver capable of producing low frequencies or bass notes.

IPX5: It is a rating that states how protected the gear is against water or dust getting into the casing of the gear. Its resistance to impacts. The higher the number, the best protection. IPX5 offers protection from a 6.3mm spray of water in any direction for at least 3 minutes.

Yoke: The part right at the back of a speaker driver on which the magnet is mounted - also contains the pole piece for the speaker motor.

Hz: short for Hertz: the measurement of frequency - a high number is a high pitched note; a low number is a bass note. The adult human ear can typically hear around 50Hz to 15,000Hz.
