Audio is not my thing, and fixing speakers neither. But I know that like in the way that a speaker can be used as a microphone also Piëzo-elements (4.4 kHz, 200 Ohm) can be used as a transducer. This way picking up the oscillating sounds of much higher frequencies. Which can be seen on the crt of any oscilloscope. A friend of mine had a electronic ultrasonic Dog-whistle and asked me to find out if it was working. I was able to find an oscillating frequency of about 26KHz.

Neil: I am glad you are enjoying the articles and by telling me this you are encouraging me to do more so I thank you and appreciate your encouraging comment.
yes, I had that in mind but the place where this guy located they have a constant power failure and they are working on the problem. I already talked my Pastor about it ( my customer also) and once it is all safely up and running we will do a lot of change safety wise. I appreciate the suggestion and have a very good day

Mike: sounded like a surgery to me LOL. I ever attempted to repair any kind of speakers but thank for the detailed input. the customer was happy the way it sounded so he did not want to replace the tweeter because it is old and did not want to spend extra money on it. have a good day

I have fixed many tweeters that are open.key is magnifying glasses and a steady hand a d alit of patiece.proublem is worse in coastal areas close to ocean.salt water.i use very fine wire from discarded ear pieces.use a dab of flux and a very hot soldering iron to melt covering on broken lead.tin each lead to bite shiny solder,then add jumper.have to be very careful not to touch cone with soldering iron.if the coil is burned from over powering you can remind coil with fine magnet wire as original.a tiny dab of super glue keeps wie in place.if paper coil form is burned you can use razor blade to cut it out and replace with home made paper form have to use imagination.i look for round house hold items laying around.somethung us bound to match.tberes special glue they use for cones on ebay.i use superglue or a little dab of epoxy with toothpick. If you are successful you should read low ohms with ohmeter.ahain patience a d a good note sleep is important for a steady hand ,but not as critical as working on cellphones. cheers

Hi all: I really enjoy reading your repair work - I learn so much from reading them! I have a suggestion for you - sell every customer a high quality surge suppressor so voltage spikes will not harm the electronic equipment. I have installed suppressors inside equipment, but external units are also quite effective, as they are on a cord about a half metre long, giving more resistance before the suppressor does the job and absorbs voltage spikes. Cheers!

"The reason there was no sound because I forgot to plug in the speaker to the system" - What an honest statement, that made me laugh too! Good job there! I wished that you could replace the Tweeter. In fact, it can be opened and rectified as I have covered it in one of my articles! The wire gets cut due to corrosion.
