Hi, hopefully this is the right place to post this question. I’m looking to build an oscillator. I have all the parts ready to order and I wanted to double check that I’m not making an obvious mistake. I’m completely new to this and I thought it would be worth a second opinion to know if the...
I am looking for an extremely loud buzzer for a personal project. I'm looking for something that is about 130 db at the source. Ideally, I would like to find something like what is used in all the personal defense keychains. The buzzer needs to be small and the voltage needs to be less than 20...
I need to create a simulation of an ideal speaker output. My professor advised me to use Thiele-Small parameters to do it. However, I have only been able to simulate impedance simulation of the speaker. Do you know a way to simulate actual sound pressure output?
I'm Kody, a new electronics hobbyist (complete random urge to become one) and found a Fischer Stereo on the side of the road. This is my second post relating to a topic like this, but can anyone tell me if it's worth selling or salvaging, and what quality parts I might find?
P.S.
My knowledge...
After a massive crash on LM386 I moved on to TDA7052. This is a very good IC so far. I want to make sound boxes and sell them. That is why I want to know more info than datasheet if available. I have some questions though:
1. How to secure the connection to reduce noise?
2. How to protect the IC...
Here's a simple 2 key piano. It uses a 6v buzzer. Its very simple, the plan was to not use chips or anything that could be hard for soldering. It uses 2 switches that I got from walmart, I then went to SRA Electronics and got a buzzer. It works great, it uses a LED to drop the voltage so it can...
I'm hoping someone here can help lead me in the right direction on an experiment of mine.
In my car I have an automatic starter that includes a wire that when given the 12v negative connection will trigger the automatic starter. What I would like to do have this negative connection activated...
Hello i have a nissan pulsar NX 1988 and when i open the doors a bell is ringing.
So i thought that i could change the sound of the bell with a custom MP3 sound.:woot:
ive seen MP3 modules that i could replace the bell with, but i need the sound to be triggered
just one time and im not 100%...
Hi all,
I'm working on an audio circuit that is really space limited. I purchased miniature 12MM 8 ohm speakers from "no name" brand from aliexpress, these speakers don't have a datasheet.
When I activated the circuit the sound is really low- even though the voltage on the speaker is 2V~3V.
I...
Hi guys im really new to electronics I have some very basic knowledge , I am good at making soldering a schematic but almost no idea what does what and why. Im a DIY fan and love doing some small projects (sound related mostly)like a "Car stereo 2.1 home audio system powered by a PC PSU " and my...
Well, I have decided to take on a rather ambitious project to start out my 2016, but I am at a loss on where to start. I know what I want the project to do, and have a decent understanding of what needs to be done, but could use a little guidance in what circuit layouts would work best.
I want...
