Loudest Miniature Speaker

Hi, I'm looking for part recommendations for a small speaker (~2" or smaller). I'd like something that is as loud as is possible for the size.

Mainly going to be using it for some simple square wavy stuff, so frequency response isn't too big of an issue, more concerned with dBSPL / general audibility.

Can anyone recommend a part they like for this purpose?

Thanks!

Full range? Or at least as full range as a 2” will go. A compression tweeter will be loud but it won’t go much below 1khz.

How will it be used? If you’ve got the room you could horn load the driver and that will give a few more dB/w

these are pretty nice for their size:

Here are some. Do remember the lower the reproduced frequency the lover the output (sort of, if you expect any “bass” out of a 2” it will be quiet. The more you expect the more the speaker will fail to make much noise).

My advice would be to go up a size and think of BMRs. I’m listening to the radio via one at the moment and it delivers fairly good fidelity.

They also crop up in some hifi speakers

I have one of these and it has a pretty decent output.

We used to do acoustic levitation experiments with small neodymium drivers that would go loud enough to require ear defenders from a driver that was palm sized.

The issue was that if you pushed them too far the coils would just melt (although they were replaceable, but at about GBP 50 a hit)

I think the complete drivers were about GBP 90 each?


Thinking about it now, i used one to do the wine glass smashing resonance thing too. I only did that one once, as it was pushing the driver, but, possibly, with some active cooling you could go further



Again not cheap, but very very loud for their size. I forget the upper range frequency but they were unusually high also.


But, budget... Would this sort of cost be acceptable? If so, ill see if i cant find the model number again.

I would imagine that the speaker choice was only one key part of the equation - power supply, amplifier and enclosure being of equal importance.

First youtube search result -

There will be plenty of others that explain things, but basically your reflecting the wave, so as to (at the right frequency) get a standing wave.

Given that a wave in air is just high and low pressure, if you generate a standing wave, you get static high and low pressure zones.

Insert something light enough into a low pressure zone, and, if its surrounded by high pressure zones, the object will not move from the low pressure area into the high pressure area.

But we're talking tiny objects. No acoustic jet packs just yet....

Was that to me? If so, this was just a bench setup, with a bare driver held in clamps. Nothing fancy at all.

No, to the original post.
But interesting video you posted above!

These things are flippin amazing.

I see they now have a 'mini' minirig which is roughly 3"

They sound great (although I see you don't really care about that) and are freaky loud.

Speakers need volume and size, to reach anywhere near full frequency.
What about a good miniature computer 3-speaker setup ? (one small subwoofer)
If you want a single rack -size unit.... a used Wohler 19" rack monitor might work.
Check eBay...
