We propose a new vibroacoustic device that consists of a string and two motors, called a wearable tension-based vibroacoustic device (WTV). To demonstrate the superior performance of the WTV over conventional wearable devices, which contain vibrators, we con- ducted two experiments. First, we measured the amplitudes of vibration of the skin while subjects wore the WTV and Haptuators. We found out that WTV is better than Haptuators at transmitting low-frequency waves over a wide range throughout the body. Second, we examined subjective evaluations of acoustic vibration for both devices. Almost all participants considered the WTV to be a better option as a vibroacoustic device. We thus conclude that the WTV is a good option for applications requiring high-quality and strong stimuli, such as listening to music and virtual-reality gaming.
