Live concert experience from your smartphone

Do you ever feel unsatisfied when listening to music on headphones? That’s because when listening to music live, the sound vibrations make you experience it through your whole body. The Hapbeat is the world’s first wearable device that lets you experience music like you would at a club or live concert by sending the sound vibrations directly through your body. With the Hapbeat, you can get the power and immersion of live music on your smartphone. This project strives to make Hapbeat a reality.

What is Hapbeat?

Connect Hapbeat to your smartphone through Bluetooth and plug in your headphones to experience music, movies and games like you never have before. It feels like everything is happening right in front of you! Hapbeat wraps around your body transmitting vibrations from your front to your back, immersing you in sound you can feel from the inside. Hapbeat delivers powerful as well as delicate vibrations for an audio expressiveness that simply isn’t possible on conventional smart phones and game consoles.

How to use Hapbeat

    1. Put it on!

    2. Wrap the string around

    3. Cennect Hapbeat and smartphone via Bluetooth or a wire.

    4. Connect earphones

    5. Play music on your smart device

Be at the show wherever you are

  • Immerse yourself in the music

  • VR games

  • Immerse yourself in a movie

  • Turn anywhere into a dance floor

How vibrations are transmitted to the body with Hapbeat

  • Motor rotates in conjunction with music
  • Motor rotation → string expansion/ contraction → good vibrations
  • Compact and powerful bass generates vibration by motor rotation
  • Delicate sound because moving parts are feather light
  • Wide vibration range from transmission by the body wrapped string
  • Utilization of iPhone vibrator and speaker in conjunction with the linear-vibrator device (iPhone uses paper instead of weights)


    ●Smaller device would be unable to produce vibrations for large, low-frequency sounds

    ○Cause: movement of weights (strength of vibrations) would be limited


    ●Larger device would be unable to produce delicate vibrations

    ○Cause: responsiveness of device would be limited due to its large size, and because the entire device is designed to vibrate


    ●Device size is proportional to the range of the body it can send vibrations through (a small device would span a very limited area)

    ○Cause: vibrations are only felt in areas where the device is placed, a large device is needed to cover a wide range

    Experiment Results

    The following paper discusses the results of the experiment.
    "Tension-Based Wearable Vibroacoustic Device for Music Appreciation."

    In the experiment, the Hapbeat and Haptuator were compared in terms of how well they transmit vibration energy. The extent of vibration is reflected by the size of the square in each diagram.
    Hapbeat conveys vibration uniformly in comparison to Haptuator, which only vibrates the immediate vicinity.
    At 150 Hz both Hapbeat and Haptuator do well to convey vibration. However, at 30 Hz, Hapbeat continues to transmit vibration well while Haptuator transmits almost no vibration.
