That device as the passive sound amplifier — is very popular product for iPhone, thus since the time of dural "old man" when for these purposes acryle was used. Late there were also other options, for example Lil Kikr from steel and aluminum. But men went to Volta Sound Company still further and made that sort the device of a tree and — attention! — bizony horn.
Namely, Volta Sound Block is executed from an alder, varnished, and the bizony horn plays a loud-hailer role. By the way, it demountable and to a design fastens by means of neodymium magnets. iPhone 5 is established in dock in the special place of landing trimmed with natural wool. Continuous natural materials and the run wild vintage for special judges.
As Volta Sound Block increases loudness of a sound — the producer does not extend. But in this case the emphasis is made quicker on external shape of a device and on materials from which it is executed. Eventually, such beauty can be used simply as a support for iPhone. Costs expensive, already $190, but for a certain category of people it that costs. [Volta Sound Company]
