Design of 800-1500W Power Supply with Multi Speaker protection
TechFusion Dec 13,2024
Please check the Video Link.https://youtu.be/8BRjHAQC76YInrush current protectionHere’s the Inrush current protection, Low frequency transformer generate very high inrush current greater than 10X the nominal current rating. During initial transformer turn ON, the primary winding act as a short circuit across the AC input until magnetic field build up, it may take 2-5 ac line cycles depending on the size of the transformer. The rectifier Bulk capacitor will also generate very high inrush cur...

Speaker Delay Circuit
swordson Nov 14,2024
This is a simple speaker delay circuit made with NE555.It connects to the amplifier output and protects the speakers.When transferring the relays to the PCB, two were used, unlike the schematic.This will allow you to use two cheap relays instead of expensive ones.Tested.However, there is a small mistake in the PCB diagram.The transistor marked as BD337 should be BC337.

*Almost Fully 3D printed Speaker
Printing Aug 31,2024
This is the basic components of a 3D printed speaker; you need to add magnets and copper wire, the plates are CNCdThe Surround should be printed in TPU or this speaker may not work. I use ninjatek TPU but it should work with everything from 85A-97A it will just change the frequency response (higher shore hardness = high frequency response-- 85A will act like a small woofer and 97A should act like a mid)Magnets are as follows - read the info at the following link before continuing:https://www.sta...

speaker network
May 13,2024
This is my first time making a PCB. It's a bit strange, but please forgive me. What I created this time is a network for 2way speakers. Please improve it yourself when using it. :)

speaker protection - intermediate
Harrison May 06,2024
Speaker protection can be used for true duo mono DC, Delay, temperature, over currentOver current protection in most amplifiers works between 50-100hz and below. DC detection is a balance between the lowest playable tone and DC detection response times most amplifiers work between 500ms-1 second, others 2 seconds and some at 4 seconds. Most amplifiers will eventually fail with or without protection due to the window of focus, however protection can be better than none.99.93mm * 99.61mm
