Ampli-Phone Pure Acoustic Speaker
Enjoy Room-Filling Sound with Surprising Fidelity
The Ampli-Phone is a scientifically designed horn that provides remarkable amplification of the speaker built into your iPhone. Place your iPhone in the dock cradle, and enjoy room-filling sound with surprising fidelity. You can even charge or sync your iPhone while it is using the Ampli-Phone®, and if you make or receive a call, you will be able to use the speaker phone function and converse from several feet away.
A Simple, Elegant Solution
The speaker that is built into the iPhone is good quality, but doesn't provide the volume necessary to enjoy the iPhone as a stand-alone music player. The Ampli-Phone® is simply a horn that is used to amplify the speaker that is built into the iPhone. The elegance comes from the careful and scientifically correct design of the horn, which provides a full frequency response and remarkable volume in a compact package. You can enjoy room-filling volume from your iPhone or iPod Touch without wires, batteries or other encumberments.
Ampli-Phone™ Performance Testing
This test consisted of 100 averages of white noise measured axially at 1 meter from the horn opening using 2 Bruel and Kjaer 4192 Pressure Field microphones, spaced 30 cm apart in an anechoic chamber. The plot is the average response of both microphones. The white noise source was amplified to 550 mw by a Bruel and Kjaer power amp, and a planar piezo sonar array driver was placed in line with the horn mouth, sealed into position using caulk. Frequency response of the source and driver is 2-50,000 Hz +1 dB.
Smoother Response Characteristics
The Ampli-Phone® provides at least 10 dB broadband gain as compared to an iPhone without the horn. This gain can be significantly increased by placing the Ampli-Phone® in the corner of a room. In addition, the bass response of the system will be enhanced via corner placement.
The overall response characteristics are considerably smoother than an iPhone speaker alone, and low frequency response is extended by a full octave.
