What do you think of resonance/vibrational speakers?

    I got two to compare - a cheapy Hong Kong knockoff and one made by OrigAudio called the Rock-It 3.0.

    These are gadgets that use vibrations to conduct sound instead of a membrane like your traditional speaker. You stick them to your stuff, and the more hollow it is, the better amplification and sound you get.

    If they actually do a good job, I've probably pick up one of the bigger ones (5 watts of power) so my mother has a pair of decent speakers with her computer.

    I think my friend had one similar where he put it on my desk and it amplified the sound? It seemed pretty cool and if you were sitting around with friends, it would be a easier, portable solution to bringing an external form of sound over external speakers. Though this is for away uses. I just don't recommend it for home since it'll make your sound feel "empty".

    They were selling these things at Comic Con NYC this year and the sound quality was pretty good lol.

    Edit: I'm probably going to stick to the under $20 version. The more powerful versions are like $70 with shipping.

    I don't care about home use - I'm usually in the dorms, and it makes it more easy to listen to music. (I usually have my headphones on...which isn't good, because it's blaring music half the time.)

    I played with some of the earlier ones in various tests all anchoring them to properly supported sheets of glass*, long story short they are absolutely fantastic if you can get them in a good situation (which is to say practically lab conditions) but real world usages as far as music playing goes are less practical. If you want them as a PA system or something of that ilk then go for it.

    *putting them on your windows is a fantastic way to annoy your neighbours so probably best not to do so.

    Roll on ultrasonic induction speakers I say

    The rock its are absolutely terrible, the mighty dwarfs are better but no company actually makes good ones. If you want a decent surface transducer based loudspeaker that will lower the coefficient of total harmonic distortion as much as possible, you are going to have to make it yourself. Good news is they aren't particularly hard to DIY, not like electrostatics.

    The problem with resonance speakers though is the fact that you have a THD coefficient and different constants for whatever material your surface is made of. If you want to listen to music, you are better off just buying a decent pair of head phones, if you want something that is somewhat novelty then go ahead with the resonance speakers
