Project Proposal

• Design and build platform for measuring magnetic
  flux and leakage of a loudspeaker
• Utilize existing Gaussmeter and incorporate a
  computer to automate the measurement process

3
Purpose

• Make test accurate and repeatable
• Remove as much human error as possible
• Allow test information to be stored and retrieved
  electronically

4
Benefits

• Make test accurate and repeatable
• Remove human error
• Allow test information to be stored and retrieved
  electronically
• Design incorporation
• Tracking

5
Voice Coil Gap Test

• The intensity of the magnetic field in the voice
  coil gap will be measured by probing at various
  depths and points around the pole piece.
• Maximum values will be recorded for each angular
  position around the pole piece then averaged for
  the final result.

6
Magnetic Leakage Test

• The probe will be placed at various distances and
  heights outside the speaker.
• Record the field leakage reading at specified
  points.
