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.

What sets Hapbeat above other wearable vibration devices?

  How vibrations are transmitted to the body with Hapbeat

 (international patent pending))

● Motor rotates in conjunction with music   
● Motor rotation → string expansion/ contraction → good vibrations 

 

Features of motor / string vibration generation

● Compact and powerful bass generates vibration by motor rotation
● Fine vibrations for delicate sounds because moving parts are feather light
● Wide vibration range from transmission by the body wrapping string  

Issues regarding the linear-vibrator device

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

・Comparison between Hapbeat & loud speaker

An experiment using a container of water was used to show how much vibrations were being emitted to the wearer of Hapbeat compared to a regular speaker. Please see the video for the results. 

Left: Hapbeat's strings sending the vibrations to a container of water Right: The sound from a loud speaker affecting a container of water (110dB)

*110dB is about hearing a car horn two meters in front of it. A normal karaoke room is about 90dB.

  • An Experiment Between Audio Signal Waves of Music and Hapbeat's Vibration Waves

Hapbeat's sound output waves (Screen: Top) and the vibration waves from its strings (Screen: Bottom) were compared. Hapbeat producing the vibrations as it synchronizes to the bass of the music could be seen.

  •  Sine Wave (10-1000Hz) Reproduction Experiment

An experiment to see how much frequency Hapbeat is able to reproduce was tested by using Sine waves. The frequency level is 10-1000Hz. Looking at the waveforms, you could see that Hapbeat is accurately reproducing the audio signal.

 

  • How does the vibration is transmitted to the body

 
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.

The Team

Hapbeat LLC is a start-up company formed by Tokyo Institute of Technology's Hasegawa Shoichi Laboratory. Yamazaki first got the idea for Hapbeat as a graduate student when he was selecting his research topic, interested in creating a device that would recreate the feeling of being at a concert. He sought out the advice of Associate Professor Hasegawa, and the concept of Hapbeat was formed. He then presented his prototype at a VR Institute. During his participation in a startup firm event, he met Oda, a student from the same school and together they formed a team. Current staff include Yamazaki, Associate Professor Hasegawa, and Oda. Yamazaki works as the overall manager and designer of the device. Associate Professor Hasegawa specializes in circuit operations and technical consulting, while Oda is in charge of marketing.

 

Partners 

Product, web and video design was done under the supervision of Tokyo Metropolitan University Associate Professor Tetsuaki Baba and assisted by TMU graduates and research students.
We have also been selected by the DMM.make AKIBA Open Challenge project and have been working with the support of DMM.com Co., Ltd., and Autodesk Inc.

Why Kickstarter?

Hapbeat was not originally developed as a commercial product it was born out of an university research project. The comfort of enjoying music with your whole body is already a great part of our lives. We wanted to share this joy with as many people as possible by making the experience more accessible. However, product development comes with research expenses. Here on Kickstarter we hope to find and gather people that love new experiences and technology, and music that will help us make this project come true.

プロジェクト概要(日本語)

ライブの臨場感をあなたのスマホで

ヘッドフォンで聞く音楽に物足りなさを感じませんか?ライブでは、音に包まれ、音=空気の振動を体で直接感じています。Hapbeatは音の振動をあなたのお腹に直接伝え、スマホの音楽をライブ会場やクラブハウスに迫る迫力と臨場感で体感させるウェアラブルデバイスです。本プロジェクトでは、Hapbeatの製品化を目的としています。

HapbeatとスマホをBluetoothで接続し、Hapbeatにヘッドフォンを刺して音楽や映画、ゲームの音声を聞くと、まるでその場にいるかのような臨場感を体感できます。Hapbeatは体に巻いた糸で振動を伝えることで、お腹から背中までを音で包みこみ、お腹の底からビートを感じさせます。また、従来の携帯やゲーム機では出せなかったパワフルかつ繊細な振動で、音の表情までもを伝えることができます。

Hapbeatと従来のvibratorとの比較

Hapbeatで振動が体に伝わる仕組み(国際特許出願中)

● モータが音楽に連動して回転
● モータの回転→糸の伸縮→振動として感じる

 

 モータと糸の組み合わせによる振動生成の特徴

● 小型かつ強力な低音振動
○モータの回転で振動を発生させるため

● とても繊細な音の振動
○動く部分がとても軽いため

● 広い範囲に振動を伝える
○身体に巻き付けた糸によって振動が伝わるため

 従来装置(Linear-vibrator)の問題

Linear-vibrator → iphoneの振動子やスピーカー(重りの代わりに紙を動かす)などで用いられている原理 

●小型だと大きな低音の振動を出すことができない
○重りの動ける範囲(=振動の大きさ)が制限されるため 

●大型だと振動が繊細ではない 
○装置全体が振動する仕組みなので、大きくなると動く部分が重くなって応答性が悪くなるため
 
●装置の大きさと振動が身体に伝わる範囲が比例する(=小さい装置では狭い範囲にしか振動が伝わらない)
○装置が体に触れているところ=振動が伝わるところとなるため.広く伝えるためには大きな装置が必要

  • 身体への振動伝達実験

上記の実験結果に関する論文はこちら
"Tension-Based Wearable Vibroacoustic Device for Music Appreciation."

Hapbeatが体にどの程度振動を伝えているのかをHaptuator(従来装置の代表品)と比較した実験です。図中の四角が大きいほど,その場所に大きな振動が伝わっていることを表します。

●Hapbeatは振動を均一的に伝えている / haptuatorは付けた箇所の近傍のみ
●150HzではHapbeatもhaptuatorも良く振動を伝えている 
●30HzでもHapbeatは良く振動を伝えているが,haptuatorはほとんど振動を伝えていない

Kickstarterで支援を求める理由

Hapbeatは元々商用に開発したデバイスではなく、大学の研究活動から生まれたものです。音楽を体で聞く心地良い感覚は既に私たちの生活の一部です。多くの方とこの喜びを共有したいと強く思うようになりました。 しかし研究費では製品開発はできないため、新しい体験と音楽と技術を愛する人々が集まるkickstarterでbackerを募るのが最も成功への近道だと考え、kickstarterに投稿することに決めました。

調達資金の用途

 タイムスケジュール

  リスク

・現在プロトタイプに使用しているモータと実際の製品に組み込むモータが異なるため,装置のサイズが数mmほど変更になる可能性があります.

・省電力化にも注力していきますが、バッテリーの駆動時間も限界があるため、最大出力で何時間も持つようにすることは保証できません。長時間大きな出力で使用したい場合は別途、モバイルバッテリーが必要になる可能性があります。

・装置内にゼンマイなどの機械部品が入っているため,耐久性について保証ができません。壊れやすい部品については交換用の部品を別途用意する予定です。

・このプロジェクトは進捗状況により、遅延が起きる可能性があります。その際は、速やかにバッカーの皆様にご連絡します。

・弊社指定の配送業者が配送できない地域にお住まいのバッカー様には、配送先住所の変更をお願いする場合がございます。お住いの地域に配送制限が課される可能性がある場合は、お問い合わせください。特定の地域には発送できない場合があります。

・弊社の故意、重過失がある場合を除き、ファンディング終了から2週間後からは返金対応は行いません。

 

Risks and challenges

Because the motor currently used for the prototype and the motor to be incorporated in the actual product differ slightly, the size of the device may change by about several millimeters.

While we are working on reducing battery consumption, the battery drive time is limited, so we cannot guarantee long play at maximum output. For longer play times at high output, a separate battery may be needed.

Internal mechanical parts such as the spring cannot be guaranteed. For fragile parts, replacements will be made available separately.

Should there be delays in fulfillment for whatever reason, we will promptly keep you informed of the situation.

As we may not be able to ship to certain areas, we may ask backers to provide an alternate shipping address. Please contact us if there is a possibility that shipping may be restricted in your region. It may not be possible to ship to certain areas.

Except for error or gross negligence on our part, refunds will not be offered two weeks after the end of the project funding.
