Micro (Legacy)

prusaprinters

This is now a legacy design and it is strongly advised you look at the Elemental or Fidelity series  Welcome to MicroA 3cm 3D Printed Full Range Speaker DriverDeveloping on what has been learnt since FD51/FD52 series, Micro is a small compact 3D Printed driver which can play lower, play louder, and is easier to 3D print and assemble than ever before. It includes the following features:Screw down magnet motors, eliminating broken capsule wallsRemovable magnet motor, allowing it to be reused as many times as you want!Single suspension design, reducing flexible filament usage and improving complianceMicro has a nominal 4 Ohm impedance, and so can run from any up to date amplifier. It is a perfect companion for the PAM8403 USB powered amplifier. Check my other models to find cabinets such as the 0.4L and 2.0L circular cabinets!Micro has had data (T&S) in 2 different filament configurations. These are:Colorfabb Varioshore + Polymaker PolywoodPLA + TPU 95AThe 1st configuration is to extract the most performance. The 2nd configuration is for more commonly used filaments. The design has been built to make both options a great experience. The datasheet also shows the frequency response when fitted into a 0.6L cabinet. Frequency response is 100< 16,000Hz +/-5dB.Attached is 2 guides. 1 for Assembling the Comet magnet motor, and the other for assembling Micro itself.Comet is a £10 (+Shipping etc) magnet motor kit available to purchase, and eliminates any wrong purchases or issues. It contains the following:2x Ferrite MagnetsMetal parts to make up the Top Plate, Base Plate and Pole PieceGlue4x 4.2M 0.17mm Blue Enamelled Wire2x 220uF Bipolar CapacitorsIf you do not have a amplifier to run this project, a simple USB powered PAM8403 amplifier board will work just fine for Micro. I am working on offering a simple amplifier for this specific purpose.If you are looking for the more powerful version of Micro, Micro+ which uses the Fountain / Peony / Firecracker motors, please check and consider becoming a Patreon. Doing so helps the project and gives you access to additional cabinet designs.https://www.patreon.com/polymate3dFinally, any questions, feel free to email me or DM me on Twitter!:polymate3d@outlook.comhttps://twitter.com/Polymate3DHappy Printing!
