A motor that uses variations in a magnetic field to move a speaker membrane or the actuator arm in the case of a hard disk drive.
Audio: The part of a speaker driver that converts the electrical signal from the amplifier into a magnetic field. This magnetic field fluctuates with the electrical signal, causing the permanent magnet to move the cone, creating sound waves.
The voice coil is the coil of wire at the apex of the loudspeaker cone that interacts with a magnetic field. With the help of other speaker components, the voice coil converts electrical signals from the amplifier or receiver into mechanical energy which we hear as sound. The voice coil former is the part of the speaker around which the voice coil is wound. More advanced speakers offer a heat-resistant (Kapton) voice coil to prolong speaker life.
This is the coil of wire through which an electrical signal is sent. When the voice coil receives a charge it becomes an electromagnet and reacts with the permanent magnet found on the back of a speaker. This reaction is what causes a speaker to move in and out. Specialized voice coil materials and winding techniques are often used to improve a speaker's efficiency and/or power handling capabilities.
A wire coil at the rear of the speaker cone that works with the magnet to drive the speaker.
An actuator motor; the force of the magnetic rotary voice coil produces a movement of the head that is proportionate to the force exerted by the coil.
The coil of wire attached to a driver's cone that receives the electrical signal from the crossover circuit. The cone then moves in the magnetic field at the center of the magnet depending on the frequency and amount of current being delivered to the coil.
The central part of the speaker that converts electrical pulses into magnetic pulses. It consists of a wire coil would around a cylindrical form.
Wire, usually copper, wrapped around a former (tubular core). When attached to a cone or diaphragm, surrounded by a magnetic field, and set into vibration by an alternating current, a voice coil causes a speaker to emit sound waves.
Small coil of wire attached to the diaphragm of a dynamic microphone.
Coil of wire inside a loudspeaker driver through which current from the power amplifier flows.
The coil of wire fixed to a cylinder at the apex of the loudspeaker cone that interacts with a magnetic field. With the help of other speaker components, the voice coil is the active transducer that converts electrical signals from the amplifier or receiver into mechanical energy, which we hear as sound.
A fast and reliable actuator motor that works like a loudspeaker, with the force of a magnetic coil causing a proportionate movement of the head. Voice coil actuators are more durable than their stepper counterparts, since fewer parts are subject to daily stress and wear and also provide higher performance.
The wire coil surrounded by the magnet assembly in a moving-coil, dynamic loudspeaker. The coil is attached to a diaphragm (which may be a cone, dome, or some kind of hybrid air mover) of the driver and causes it to move when excited by a signal from an amplifier. Most voice coils are made from copper wire, although a few are made of aluminum wire.
Coil of wire wrapped around a tube and attached to the speaker cone or driver diaphragm. Becomes an electromagnet when an audio signal is applied and interacts with a permanent magnet which causes the cone or diaphragm to vibrate.
A tightly wrapped coil of wire attached to a speaker driver's diaphragm that works with the magnet to provide a motor to drive the speaker.
The wire wound around the speaker former. The former is mechanically connected to the speaker cone and causes the cone to vibrate in response to the audio current in the voice coil.
The voice coil is the coil of wire in a loudspeaker that creates a magnetic field. With the help of other speaker components, the voice coil converts electrical signals into mechanical energy which is used to produce sound. The voice coil former is the part of the speaker around which the voice coil is wound. Many of the speakers on this site offer a heat-resistant voice coil to prolong speaker life.
Wire (usually copper) winding around a cylindrical former that is glued with the speaker membrane. Alternate current passing through mobile voice coil generates a magnetic field that interacts with the one occurring into the gap; the vibrations that derive from this are sent to the membrane, generating sound.
The coil of wire in a microphone or a dynamic loud speaker which, in conjunction with a magnetic field, converts electrical signals to physical vibrations.
A coil of wire attached to the rear of the speaker cone that works with the magnet to provide a motor to drive the speaker. The hookup wires for a speaker connect the head unit or amplifier output to the voice coil.
Coil attached to the diaphragm of a moving coil loudspeaker. The coil is moved through an air gap between magnetic pole pieces.
Located inside a loudspeaker, the voice coil (a small coil of wire) creates a magnetic field. With the help of other speaker components, the voice coil converts electrical signals into mechanical energy to produce sound. Many of the speakers on this site offer heat-resistant voice coil to prolong speaker life.
A voice coil (also known as Bobbin, Collar and Winding) is the coil of wire attached to the apex of the moving cone of a loudspeaker. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.
