The haptic sensation of low-frequency vibration plays a vital role in the music listening experience, but it can be enjoyed only in certain facilities and environments. Many haptic devices have been proposed to convey music audio-induced vibration for various situations. Such devices require powerful, low-frequency vibration output and transmission over a wide area. Making such devices small and user-friendly is difficult, hindering their popularity. To promote haptic devices for music listening, this paper describes a method for developing a practical device using motors and a thread and evaluates this method's effectiveness. The proposed necklace-type device is small (about 55 × 58 × 15 mm), lightweight (58.5 g), and easy to wear, making it suitable for use during everyday travel. In addition, it can transmit low-frequency (20 Hz) vibrations, whose amplitude exceeds airborne vibration in a nightclub, to a wide area across the chest and neck, with a total power consumption of approximately 2 W. Our proposed method will contribute to the development of practical and high-performance haptic devices for music listening.
低频振动的触觉感知在音乐聆听体验中起着至关重要的作用，但它只能在某些特定的设施和环境中享受。已经提出了许多触觉设备来为各种情况传达音乐音频引起的振动。这些设备需要强大的低频振动输出，并在广阔的区域内传输。使这些设备小型化和用户友好化是困难的，这阻碍了它们的普及。为了推广用于音乐聆听的触觉设备，本文描述了一种使用电机和线的实用设备的开发方法，并评估了这种方法的有效性。所提出的项链式设备体积小（约 55×58×15mm）、重量轻（58.5g）、佩戴方便，适合在日常旅行中使用。此外，它可以将夜总会中空气传播的振动幅度超过 20Hz 的低频振动传输到胸部和颈部的广阔区域，总功耗约为 2W。我们提出的方法将有助于开发用于音乐聆听的实用和高性能触觉设备。
