TDK partnered with Joe Grand, the renowned inventor and white-hat hardware hacker, to create the "world’s thinnest boombox" using the ultra-thin TDK PiezoListen line of speakers. These piezoelectric transducers start at a thickness of just 0.49 mm, making them among the thinnest of these types of devices. Thus, designers can overcome often-difficult installation space constraints.
The flexibility of these speakers makes it possible to produce sound from many kinds of objects and materials, with a high sound pressure even at low voltages of 24 V p-p or below. They produce sound over a broader frequency range and with a greater output in the low range than conventional piezoelectric speakers. The products resulted from the development of a low-profile, high-displacement piezoelectric element reflecting TDK's proprietary multilayering and material technologies.
