The voice coil (3) is fixed at the edge of the diaphragm(2).

The turns of the voice coil (18) are spaced apart (d).

A loudspeaker which has a transparent diaphragm and a big voice coil, includes a diaphragm(2),a corrugated rim(1), a voice coil(3) and a magnetic circuit system.

A conducting wire on the voice coil is welded to the flexible board.

The diaphragm is connected directly to a voice coil in the headphone, with the voice coil moving between magnets to produce sound.

A magnetic motor system for driving a loudspeaker voice coil.

The system has first and second parts that define a volume for receiving a voice coil.

The PCB coil linear actuator is intended to replace traditional slotted bobbin voice coil actuators (VCAs) and is particularly useful in fast steering mirror (FSM) applications.

The voice coil is connected to the diaphragm and a part of it is arranged in the magnetic gap of the magnetic circuit.

(2) the speaker does not exceed the power of its rated power, otherwise, will burn the voice coil, or voice coil dispersion.

A voice coil (12) supported on a tubular former (8) is disposed within the gap (7) as is a conductive skirted dome (13).

Bl is generally maximum at rest, and drops as the voice coil approaches Xmax.

The diaphragm is firmly fixed to the voice coil when the adhesive agent hardens, which enables the diaphragm to be driven at a high output.

The terminal electrically connects the external circuit with the voice coil by utilizing the spring pressure when the metal plate is bent.

The connector section is provided on the rear surface of the magnetic circuit, and includes a terminal connected to a lead line of the voice coil.
