Custom Voice Coils for Speakers and Audio Drivers
Voice coils convert an audio signal into controlled movement inside a speaker motor. JHCOILS works with custom coil requirements for speaker and driver applications.- Home theatre systems
- Professional audio
- Compression drivers



Designed Around Your Speaker Motor
Voice coil geometry and winding details need to match the available space and the target electrical characteristics.Winding Targets
Include wire information and electrical targets such as resistance or impedance, along with the measurement conditions when available.Assembly Details
Note the former, lead arrangement, connection points, and any mechanical or thermal requirements relevant to the driver. Working principle
How a Voice Coil Moves a Diaphragm
A simple view of the relationship between the electrical signal and speaker movement. 01 · Signal
Current in the winding
An audio signal drives current through the voice coil winding. 02 · Force
Interaction in the gap
The coil operates within the speaker motor’s magnetic field, producing force as the signal changes. 03 · Motion
Diaphragm movement
The moving coil is coupled to the diaphragm, creating sound pressure in the surrounding air. Start with your requirements
