Audio Raspberry Pi
« on: October 18, 2014, 06:52:10 pm »
I'm building something with the pi.

I've tried usb speakers, and the ones I have sound like a hornets nest when no sound is playing. (Looking for new ones)

I wondered how many cheap options for audio on an RPi there is.

I know of audio amplifier boards, but they're way too expensive.

Just thought it might be worth a discussion.

I'll look into this properly later but if I remember rightly there is a fairly cheap board you can get that works as a good RPi sound card.

I have a cheap usb sound card, but it doesn't seem to work with the OS I am using very well. But I've tried headphones and they're working excellently off of the 3.5mm jack socket fine, so looking into cheap speakers that purely use the 3.5 for power.

You would be better to get a USB to power adapter. Like phone chargers use. Then you can use the speakers using a wall socket?

Quick Google search for "non-usb speakers" throws up loads that are run on mains power, but I am sure the above method would work too. Should also be able to get one for like £5-£10 absolute maximum since it's available with phone chargers.

Here are some non-usb speakers though:

I have been using usb powered ones, I have only 4 usb sockets for the project I am using it on.

I have expensive usb speakers which seem a tad too sensitive to interference. Therefore, looking for either cheaper ones or 3.5mm jack powered ones.

This is being powered by a usb hub, and will be built into a device.

Finding speakers powered just off 3.5mm will be extremely difficult if not downright impossible, especially for a cheap price. The speakers need a decent source of power, so your options are either USB or Mains.

You can get little battery powered ones, don't know what the life is like on those tho.

Not that great to be honest, the power consumption affects the quality so for a decent set of speakers the batteries wouldn't last long at all.

I want ones that either have a built in battery, usb charging or usb powered, or 3.5mm jack powered. And its not impossible, just not loud volume.

I don't need anything booming lol

I am considering doing some diy with a pair of headphones I have spare, that have a snapped bracket so they can't fit on my head now anyway.

If you can go with USB powered then great.. otherwise if you only want a small amount of sound then there are chargeable ones (via USB cable) such as the X-Mini
