Polarity on speakers? Answered

I have about a dozen little 4-8 ohm speakers out of toys and alarm clocks. I noticed that while most of them have no markings, one of them has a little plus and minus polarity markers on it. Does polarity matter on cheap speakers, and if so, why?

Crystal Speakers? Answered

I'm planning on building myself (or modifying my existing one) to create the ultimate workspace and among the several features I have planned (usb hub etc) I have one particularly tricky one, I'd like to integrate the desk with a speaker system but massive drivers wont cut it on such a small surface area. I had recently seen a speaker system that uses glass or crystal vibrating to create amazing sound, I was wondering how I'd shape such crystals and if anyone has any general ideas on the design of the speaker system  ?

Speaker resistance?

I have an amp schematics and for the speaker rezistance it says 8 ohms. I have 4 ohm speakers so I am worried that amp circuit will burn. Will it be ok, or should I put a 4ohm resistor in series with the speaker. The chip is TDA2615. Power source is 12v lead-acid battery.

What is this? (speaker circuit)

I found a pair of broken speakers in a junkyard a while ago and wanted to take the good-looking connectors.

Mismatching speaker wattage?

Hey guys, So I've recently gotten into making DIY speaker systems, but I'm having trouble understanding the whole ordeal about wattage and ohms. I have four speakers I managed to salvage from some old speaker systems that I got from an old thrift shop. I have two 15W 4ohm speakers, a 20W 8ohm speaker and a 2W 8ohm speaker (but I don't think I'll find a use for that one, I'm not sure) I plan on buying the Lepai LP-2020A+ amplifier, it's a two channel amp and delivers 20W/ch with impedance of 4-8ohms. What I want to know is what set up would be best with what I have? Can I run the two 4 ohm speakers on 1 channel even though they would draw 30W of power? I'm a bit new at this, and my understanding is still a bit unclear so if anyone could please explain, I would very much appreciate it :) Thank you

Bluetooth speaker not turning on?

Hi, i made a basic DIY Bluetooth speaker with a glass box. I used one 18650battery from old laptop, a charging module with protection circuit inbuilt,one stepup module to step up 4v to 5v and a 3w amplifier. It's a basic project, but the thing is WHEN I TURN THE SWITCH ON(AMPLIFIER POTENTIOMETER IS OFF) I SEE LED BLINKING ON BLUETOOTH MODULE, MEANS IT'S WORKING ,THE CIRCUIT IS OK. THE MOMENT WHEN I TURN ON THE POTENTIOMETER ON OF THE AMPLIFIER THE SPEAKER JUST SOUNDS LIKE "TICK" AND BOOM EVERYTHING SHUTS OFF. I TRIED TO MEASURE THE VOLTAGE COMING FROM STEPUP MODULE SAYS "0"V. SO I PLUGGED A CHARGER ON CHARGING MODULE AND THEN TRIED TO TURN ON AND FIRST 2 SEC SPEAKER MAKES SOME SOUND AND IT TURNS ON AND PLAYED SOME MUSIC, IT WORKED GREAT. THE THING IS WHENEVER I'M TURNING ON THE AMPLIFIER VIA POTENTIOMETER OR THE POTENTIOMETER IS ON AND I SWITCH ON THE POWER FROM THE FIRST SWITCH THE POWER CUTS. SO WHAT'S WRONG WITH THE SPEAKER. PLEASE TELL ME :(

Opposing coil speakers?

Today's speakers have large heavy magnets, but what would be the result of setting up two coils which create opposing fields, one being the typical voice coil, the other being a replacement for the magnet.  Why isn't this in use today, is the power needed to create the required field just too great? This method could be used to increase volume while not overloading the voice coil right?

Laptop Speakers Broken ?

Hello, everybody. I have a problem that is really driving me crazy and I was hoping that someone could help. The sound has gone out on my HP dv6131. At first I thought it was just a Vista issue, as the computer originally came with XP, so I tried updating all the drivers that I could could think of (Conexant), but none of them helped. Next I plugged in headphones and realized that I can get sound through my outputs, but there is also no input through the internal mic. I can however plug in a mic just like I can headphones or external speakers. When I go into the control panel and play music the mixers show that everything is working. I'm sure it's the speakers, but I'm really hoping it's something I can fix. I just have no idea where to start. Will someone please help. I have worked myself into delirium with it and I am desperate. Thank you.

Current Problems with speakers...

Hey guys, I've uploaded some pictures of my problem. What I have here is an attempt to add bass to my speakers - I'm a newb, so this isn't going so well. The music is comeing from an iDock, and is being routed in parallel to a set of computer speakers. The right speaker has volume & tone knob, the left is simply plugged into the right. I unplugged the left speaker, took the circuitry out, and connected its input & output to a larger bass speaker - quickly was I suprised with a smoking capacitor (lol how healthy!) so... what should I do, simply add a resistor? Edit: Note the resistor (brown red red = 12k? or 1.2k?) is only in series with the LED and is not affecting the bass speaker. I am just wondering how a bass speaker could draw MORE amperage than the small speaker without any circuitry?

Simple, speaker question. Answered

Hello, All I want to do is create a very low, and reasonably audible hum or drone from this speaker ; about as loud as a person humming as hard as they can before their throat hurts and they start coughing. Is it possible to avoid an amplifier and just run a voltage into it so that it just makes a single tone as described ? If so: I found this big broken speaker in the road. As you can see, the Cone is missing a section, but the surround and spider are intact. The cone is credit card thickness plastic. Is it feasible to just patch it up with some similar plastic and contact adhesive; it does not have to be a good sound, just a drone. I realise that my grasp of electronics is child like and readily accept the impending abusive comments and links to the Google homepage. Thank you  FOH
