Duo Wireless is a model designed for use in situations where vibrating content is provided to a large number of people, mainly at facilities and events. It utilizes the ESP32 wireless module and can be remotely driven by Wi-Fi and other major wireless systems. The internal mechanism is almost the same as that of Duo 2, and it also supports wired input, but audio output is omitted.

This product requires programming and is intended for developers. It is necessary to write firmware and voice data to Hapbeat using VSCode as needed. If you need low latency (a few milliseconds) communication, we recommend using ESP-NOW, but you will need a separate transmitter using an ESP32 microcontroller (e.g. M5Stack).

Please contact us for more information about ESP-NOW.

Reference price: 40,000 yen (including tax)

The reference price is for the main unit only. We will support the introduction of general-purpose firmware provided by our company, but individual development costs are not included. We also offer system development services, so please contact us if you are considering introducing the system to your facility.

Development Image

The basic flow of the system is that Hapbeat stores the voice data for vibration drive and sends text commands (e.g., '0,0,0,0,0,0,50,50,0') for playback via Wi-Fi, ESP-NOW, etc. The system is then driven by the user. It can be implemented relatively easily by touching the code of the system to be introduced. For example, in the case of Unity, a transmitter such as M5Stack can be wired via USB, and at the timing you want to send vibrations, you can send text commands to the transmitter using serial communication (firmware for the transmitter is provided).

  1. When all LEDs, displays, vibration output, etc. are turned off until the drive signal is received

  2. This is a guideline when playing an EDM track that is constantly vibrating on battery power and looped at maximum volume. Continuous use while charging is possible.

  3. Measured values with Duo are common to all models.

  4. Approximate: a few milliseconds with ESP-NOW, 1 second with Wi-Fi (via MQTT broker)
