iBamboo Speaker Amplifies Sound Without Using Electricity

By - Source: iBamboo | B 21 comments

Bamboo iPhone dock provides a wireless, eco-friendly boost in sound volume.

Designed by Etsy user Anatoliy Omelchenko, the iBamboo speaker offers iPhone/iPod touch owners a chance to give their tiny little phone speakers an electricity-free boost. All you have to do is slip your phone into the hole on the top and press play, no need to worry about plugging any wires in or charging any batteries.

Created out of real bamboo, iBamboo uses the properties of sound resonance to amplify the volume of the iPhone. Although it won't be as effective as traditional speakers, iBamboo provides a stereo-like effect with a noticeable bump in volume whenever you need a small boost on the go. The device sells for $25 and can be ordered directly from the iBamboo website, though it is currently out of stock.

    kind of overpriced for a 0.1$ dollar item.

    might as well chop one off yourself and make something like this by hand for free!

    is it possible to use this with other device? don't want an iPhone/iPod

    No it does not amplify the sound. That is physically impossible without an input of power. It may direct the sound and make it louder for listeners in the direction(s) it is facing. Pretty bad for a techie website.

    I would like to know the frequency response of this.

    @arlandi
    As long it fits in the hole and has the speaker inside, it should work for any device.

    I like the idea, but the name is rather disconcerting.

    There is an amplification effect due to noise channeling and reverb.. not impossible, its how those cheer megaphones work, as well as most "brass" instruments.

    But yes, i agree its out of place here at toms.

    "noise channeling and reverb..." ?

    It is more accurately described as an increase in radiation efficiency, due to a better impedance matching between loudspeaker and the air. And whether you call that amplification, or not, is just a matter of taste. The total radiated sound power would must definitely go up, for such a device.

    This is not amplification but just redirection - the bamboo works by redirecting (some of) the radiated sound waves. So to the listener it does may louder but the total emitted energy is the same as before.

    I really wish we could get away from this stupid ass i____ naming scheme. iGTFO with that crap.

    is anyone there who thought of 'Law of Conservation of Energy' when first read the title on front page?

    "The law of conservation of energy" states that the total amount of energy in an isolated system remains constant over time.

    In other words there is no 'amplification' without input of more energy.
    The 'louder' sound is the result of redirecting the output from a prob. 360 degree to a narrower area of something like 120degree. So while one spot gets more volume anothe will get less. Ergo the total 'loudness' of the system is the same; actually a bit less as the Bamboo will drain some of it of course.

    guys, learn about resonant frequencies. Residual resonance from the wall of the bamboo adds to the sound as it comes out giving an additive affect tah actually does result in more deciBells. Speaker cabinet makers have been trying to supress resonant frequencies for years to kep the signal as clean as possible. This sort of additive resonance is generally dirty because it adds colour to the sound that was not originally in the recording, but correctly tuning an enclosure can sometimes add a nice warmth to a sound and yes.. amplification without electricity. It's just addig sound still bouncing around, as well as resonant sound produced by the walls and adding them to the sound still coming out.

    Of course not. the i alone is worth $30.
