Hello, who likes sound systems
Topic by The nerdling
So here goes, I am trying to figure out how to make basic sound generating machines. Preferably generating a sound that can be modified with a potentiometer or something of the sort. The principle is simple, these will be for messing around, possibly, if the result is good, using in some random recordings of mine, so most of the machines will have a jack out plug. Anyhow I was wondering, what, in a circuit, actually makes sound, what is the base of all sound generating electronic devices (synth, analog stuff, beepers) what actually creates the wave, the current that is sent to the speakers? Have I just answered my own question by saying current? Is it just the electrical current, and putting random resistors, capacitators, potentiometers and stuff changes the sound that is generated? Any help is more than welcome! and if anything good comes of it, I'll post some sound clips!

I am making a robot, and want to make it say "mole-e." I want it to be a clear reference to "wall-e." There is a long story behind why I want "mole-e," so I won't go into that. I am planning on making a very simple mp3 player that is triggered by an Arduino. Basically, I know HOW to make the robot produce sounds, I just don't know how to make it say "mole-e." There are mp3s and oggs readily available of the "Wall-e" sound bite, but does anyone have a clue as to how I can sythesize it to say "mole-e?" Any software reccomendations or tricks? Can I record it and then edit it to sound like "wall-e?"

Hello, I recently purchased this item from ebay. It's a "30s Light Sensor Record Device Module Music Box Sound Chip For Greeting Card" It comes with a pre-recorded happy birthday song. Now I want to change that song and I am pretty sure it can be done somehow, because I can see some connections available, except I am not sure what they mean and how to use them. The seller responded that there is no documentation and if I want certain sounds I have to send them the files and they will record them for me before shipping... which is ridiculous... I want to be able to change the songs when I please. The connections marked on the board say: TG1 TG2 TG3 GND VDD PW1 and PW2 Any suggestion could help.

I bought a cheap answering machine, but it's too big for the container I want to put it in. What parts can I use from it? I just want it to record a sound and play it back when a button is pressed. Also, I salvaged a part from a touch lamp. How can I incorporate this for the power?

Good Afternoon everyone, A friend of mine asked me to help him build something and I sort of hit a snag in the process. I know how to make LED's flash to the beat of music but what he wants is so that way when there are sounds around him the LED lights flash with the sounds around him (Such as if he was at a party, the LED lights would flash with the beat of the music even though they weren't connected to it.) Is this possible and if so what would I need to build or get? Thank you! Sincerely, Khris

Is there a machine or something you can make where you can plug in sound effects files and then as you push different buttons it will play the effects on cue? I have been searching and can't seem to find anything. Thanks for the help.

Hey there fellow modders/hackers/builders. I am in need of your help. First off, my keyboard is broken so I may miss some mistakes. Now to my problem, I have an idea for a project but have run into a problem... How do you add a single sound to a project? I just need one sound to play when a button is pushed. After some Google searching, I didnt find anything that could help me. So if any of you know of a way to fix my problem please please let me know. Thanks in advance!

I've always wondered how these doorbells and other such devices play a particular recorded jingle or a song.I think its possible to make circuits which can play custom tunes set by us(maybe using a PC).Could you please give me a brief idea on how this is done?
Question by Adarsh_tronix | last reply
Hey all, Here's an idea maybe one of you solder-jockeys can help me out with: Ever have a sound that you'd like to find the source of, but your ears can't tell you where it's coming from? I'd like to build a circuit to do that. I was thinking of something like three electret microphones with op-amps between them in differential mode. That would give three signals that would be, presumably, the ratio of sound coming from each mic. (And, therefore, an indication of direction.) Of course, I'd also like to get an adjustable bandpass filter in there somewhere to isolate just the sound I'm looking for. That's the part that complicates all designs I've thought of. And then, if I could somehow figure out distance too, that would be the ULTIMATE! Here's one possible use case: A car makes a funny squeal noise a highway speeds. The mechanic takes out this device and magnets it inside the hood. He runs a control wire back to the cabin. Once the car is in motion and making the desire noise, he adjusts the BP filter using potentiometer(s) and a pair of headphones. The device tells him where (relative to itsself) the sound is coming from. Your bill is less because the problem was diagnosed quickly without a lot of guesswork. Thoughts?

Hey, my friend is a drummer and he's trying to install LEDs inside each one of his toms that would come on when he hits the tom. He doesn't know anything about electronics so he asked me and I don't know much either so I'm asking all you awesome people at Instructables. What I want is a simple sircuit that will not cost me above £5 that will allow me to do what I mentioned above. I have a soldering iron and can solder stuff easily so I just need the parts and (preferably a stripboard) layout. He will be using a max of 16 red 2v 20mA LEDs in each tom so the circuit will have to be able to supply either approx. 32v 20mA if in series, or 2v 320mA if in pararell. So, any recommendations?

I'd like some instructions on how to make a button that plays the same 2-3 second audio sound when it is pressed. It should be able to last for a pretty long while if you know how to do that. I want it to look like it's DIY and not from a factory but also good enough that someone would put it on their desk. I need the cheapest possible way to do this as well as instructions for a dummy who doesn't know much about technology. Thanks to anyone who can help!!

Hello!! I am planning several Halloween props that will benefit bigly from sound effects. For instance...I'm working on a mantel version of the demonic grandfather clock in Disney's Haunted Mansion. It would be awesome to have the sound of the ominous ticking, backed with a chime, that the "real" clock has. This could be an audio loop of just a few seconds. Some of the other parts of my scheme would be enhanced with short loops of sound effects or mood music...a minute or two at most. I don't have a background in electronics, but I can follow directions. Any advice on constructing a few, small sound effects modules? Thanks!!

Whenever I play music out of my computer, a thing keeps popping up called Realtek HD Manager saying that I've plugged something into the microphone socket! I've checked both of them (Front and back) and nothing is in them! So I disabled by going: Start > Run > 'msconfing' > Startup, then disabling it. It told me to restart my computer for the changes to work, and when I booted it up again it had no sound, so I turned it back on and rebooted the computer and it still dosen't work! And yes, I have checked all the obvious things like if the sound's muted. Thansk, Flannel UK

Acoustic method could quickly catch counterfeit coins.You might assume that counterfeiters only bother with high-value bank notes, but there is a chance that some of the coins jangling around in your pocket right now are fake. If Mototsugu Suzuki gets his way, it may be that jangling that gives them away.Suzuki, a researcher at the Tokyo Metropolitan Police Department's Criminal Investigation Laboratory in Japan, has developed a way of examining coins based on the sound they make.In Suzuki's method, coins slide down a slope and then fall onto a brass block. The sound they make on impact is relayed via a microphone to a computer.Although the human ear cannot usually tell the difference between real and fake, a computer can. Genuine 500-yen coins showed four distinctive peaks of natural resonance frequencies in the 5-20 kilohertz range. This was not the case for fakes; some fakes produced only three peaks, while others showed four but at different frequencies to genuine coins.In addition to helping detect counterfeits, the sound data could be used to build up a database of fake coins, suggests Suzuki. This might help law enforcement officers to prove how many coins one counterfeit operation is responsible for. This would make for an awesome Instructable! Start with these two Instructables and get dropping pennies! https://www.instructables.com/id/Build-a-dsPIC-Oscilloscope-and-Spectrum-Analyzer-/https://www.instructables.com/id/Low-speed-AVR-oscilloscope/

Hear me out before you think about commenting. Ive got my LG R405 here, and i really like it, i added line out to it and use my sub with it. its all good, but some songs (whether the sub is plugged in or not) make my sound card cut out. (IE it'll make some white noise then stop producing sound) i have to skip the song before my sound will come back online. I was wondering what could i do to fix this? im guessing its something with the capacitors, being SMD caps, they might not be able to let the sound control chip handle the big changes in sound frequencies or something, im not too sure. dont try and tell me its impossible to resolve this issue. it is not a software problem, it is a hardware problem. i need to upgrade something, be it the capacitors, or maybe the amount of current supplied to the sound driver chip. if its capacitors, where should i be upgrading them? on the outputs or the input voltage?
Question by zack247 | last reply
I have a little toy that makes noise when you squeeze it that I want to give as a Christmas present, but tiny little hands have trouble doing the squeezing properly, so I want to do a little surgery on it so that the sound activates with just a gentle touch instead. Such as if you flick it, pet it, pick it up... that sort of thing. I know when I was little, we had a doll that was supposed to make noises when played with, but it was so sensitive that it would go off from just the blow of our AC. My problem is, I've no idea what parts I need to do this. Can anybody help point me in the right direction? And I only have about a three inches to work in, so it needs to be fairly small. Thanks.

I need to create something for a class project. Basically I need something that will "scream" (play a pre-recorded sound) whenever someone gets close to it. I have almost no experience with making things like these. I imagine I will need a motion sensor of some kind and a set of speakers? What else would I need? What are some next steps? My friend told me something called an arduino might help me.

I've created a resin cast of a gun (raygun) from a video game (Black ops 2) and as part of making it as authentic as possible I would like to have it emit sounds I've pulled from the game at the press of a button, much like a toy gun. I don't know where to go with the idea from here. I would like something that's relatively easy to hear and not too quite and powered by batteries. If someone could point me in the right direction as far as parts I would need to achieve this I would appreciate it.

I need a sound playback/recorder IC for a certain musical instrument that I am building. 25 buttons will be attached to an ATmega644 microcontroller, and the microcontroller will tell the sound IC to play a different sound for each button. The problem is that I haven't found a chip that will store so many sounds seperately, so do you know of any???I've seen the Arduino Wave shield, but I am looking for something with not so many parts.EDIT: I have decided to use the wave shield design, so I don't need any more feedback, unless you have a really brilliant idea

I'm looking for advice. (now this is difficult to explain but I'll try my best) I am trying to design a way to have a dance floor in an open area that will have an area where you can hear the music but away from the area it can't be heard. I'm attempting to do this using an array of speakers around the dance floor that will cancel out the music past the dance floor. Each speaker will face away from the area and be equipped with a microphone (directed torwards the main speaker) that then goes through and amplifier and then to the speaker (wired up so that it will emmit an opposing sound wave). This would essentially create a sound barier. I have attatched a picture as a visual aid.

I know I already asked a similar question, and I have been looking at the ISD chips (mostly the 1110 and 2100), but they don't seem to be available to buy anywhere in the UK. I am looking for a sound record/playback chip that stores medium-quality audio, only about 1-2 seconds (I believe the ISD 1110 holds up to 10 seconds, but can be cut off early). An internal ~1w amplifier would also be handy, but not necessary. The chip needs to be fairly simple to implement, have non-volatile storage, and be available in both DIP and either SOIC or QFP packages, as well as being readily available in the UK. A microcontroller that does so would also be good, I have looked at PICs and PICAXE chips, but it looks like they only do polyphonic tones or very low quality short audio with a lot of effort. I believe the ATTiny 2313 does audio playback as I have seen a lot of kits that utilize this chip.

Want to configure my 7.1 sound card, which is embedded in the motherboard. Run windows 7. I used to just split the 'green' channel between my small 2.1 computer speaker system and home built full range 'rear' tower speakers with passive crossover, powered by an old 2X 100W RMS Sony amp, with very satisfactory results (movies, mostly reggae music). But finally I got a nice 10" subwoofer! Time to make a proper setup! So I tried to plug the tower speakers in the black channel, and for now, the headphones, in the orange channel (while wiring the sub into a 4 X 40W mono setup- Parallel , I assume????). To the control panel, sound, manage audio devices, speakers, configure (5,1 for now). Works like a charm: all tests OK, can hear all test sounds. Restart... But W Media player, as well as other players (want to customize with Foobar_X_over eventually) don't provide any sound, except for the green channel. What am I doing wrong?

Question by Spaceman Spiff
A Velleman sound-to-light kit (Radio Shack MK103) is a small circuit board powered by a 9v battery which lights LED bulbs when an audio signal is received by the microphone. I would like to connect this board directly to the headphone (output) jack of my audio device (metal detector), thereby bypassing the microphone input. This would allow visual operation of the detector without the use of headphones. When an object is detected it would illuminate an LED as opposed to sending an audio signal. Is it possible to de-solder the microphone on the circuit board and solder in a 3.5mm male connector which would plug directly into the audio output device? I have never worked on a circuit board before and I have ZERO knowledge of electronics, but the kit is only $8 - so I think it's worth a try - if the electronic wizardry is correct, that is. Thanks in advance for any help! -Bruce
