As is known, third-party vendors have released hundreds of devices that work in tandem with the iPhone. iAcoustic is one of the devices.
It is designed as an old gramophone, and consists of a metal horn, which is fixed on a wooden base. According to the manufacturer, iAcoustic is a very good amplifier, whereby the tracks sound clearer and louder than a smart phone with built-in speaker.
To work iAcoustic not require a power source, because the device uses the classical principles of acoustics. However, the gadget could amplify the sound to 60 decibels. In this case, the sound of iAcoustic is significantly different from the published modern electronic amplifiers, leaving us in an atmosphere of bygone era gramophones.
