voice coil

An air decoupling mechanism was designed to place the voice coil actuators on the base and effectively reduce the motion inertia.

For the technical requirements, the voice coil motor which has two degrees is chosen as the main actuator, to pick and place chips.

It serves as a lubricant, improves thermal power &damping, aids in voice coil centering, and reduces distortion.

When an audio current passes through the device's voice coil, it creates an alternating magnetic field that moves a stiff, light diaphragm.

The function of voice coil motor in the flip chip process is to complete three movements: pick, orient and place.

Voice coil motor is characterized by being of high acceleration, high speed, smooth force, fast response, small-volume, light-weigh.

The voice coil motor(VCM) in high bandwidth actuator assembly has special voice coil construction and magnet arrangement.

VOICE COIL The voice coil is relatively short so that it remains within the magnetic gap even during peak excursions.

The principle of voice coil motor is analyzed, and the mathematical model is built. The motor's transfer function is digitized.

A schematic diagram of the voice-coil actuator drive [2] is shown in Fig. 1.

The other half of the equation is the cone assembly attached to the voice coil.

The suspension keeps the voice coil in position in the gap of the magnet.

The Voice coil is a part of HSA, Voice coil and the magnets form Voice Coil Motor or VCM.

This paper presents a novel way of laser beam steering based on micro lens array and driven by voice coil actuator.

LF Driver: 5 inch Kevlar curved cone with high temperature voice coil and damped rubber surround.

Next chip is Voice Coil Motor controller or VCM controller.

Subwoofer 12 "Tray (3 " voice coil diameter), precision low-frequency unit.

Subwoofer 10 "Tray (2 " voice coil diameter), precision low-frequency unit.

The high output 8 inch diameter woofer uses a high temperature 2 inch voice coil for sustained high output levels.

A kind of automatic assembly workbench based on PLC and pneumatic for voice coil is expatiated in this paper.
