Open-Source Bluetooth Audio System Launched by Teufel
Teufel Audio's MYND Speaker Pioneers Open-Source Repairability in Bluetooth Speaker Market
In a groundbreaking move for the consumer electronics industry, Teufel Audio has open-sourced the design files for its MYND speaker, making it the first commercial Bluetooth speaker to place a strong emphasis on repairability, modular design, and sustainability [1][2][4]. As of mid-2025, very few companies beyond Teufel Audio have publicly adopted this model of open-sourcing their Bluetooth speaker design files.
The MYND speaker's design files, which include schematics, PCB layouts, firmware, and 3D printable housing files, are available under the Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) license, allowing for the sharing and adaptation of the speaker's design files [1][2]. This approach enables users to repair, modify, and maintain the hardware themselves, a feature that is uncommon in the Bluetooth speaker market.
According to Jenny List, who proclaimed in 2021 that users should be able to fix their own devices, the MYND speaker's design is a testament to this belief. The speaker was developed by a team that includes Jonathan and Erik from Teufel Audio, with the design influenced by their previous work on the MYND speaker [2].
One of the standout features of the MYND speaker is its ease of repair. Unlike many other devices, the speaker's case was designed to be easy to open with minimal use of adhesives, allowing users without specialist knowledge to replace the battery when it dies [1]. In addition, the company developed its own speaker drivers, but off-the-shelf replacements can be used instead for added convenience.
The MYND speaker's design encourages user repair and self-replication, making it a more sustainable choice in the long run. The latest speaker from Teufel Audio, named MYND, continues this commitment to end-user maintenance.
While the open-source hardware approach of the MYND speaker has not yet been emulated by other major Bluetooth speaker manufacturers, it represents a significant paradigm shift in the industry [1]. As consumers become increasingly aware of the environmental impact of electronic waste, it is possible that more companies will follow Teufel's lead in promoting repairability and sustainability in their products.

The MYND speaker, a revolutionary device from Teufel Audio, showcases open-source design files for its hardware, making it compatible with various smart-home devices and other gadgets. This technological innovation, unlike many commercial Bluetooth speakers, emphasizes repairability, modular design, and sustainability.
Aside from Teufel Audio, only a handful of companies have adopted the open-source model for their Bluetooth speaker designs as of mid-2025. The MYND speaker's design files, available under the CC BY-SA 4.0 license, include schematics, PCB layouts, firmware, and 3D printable housing files.
Given its user-friendly design, the MYND speaker encourages its owners to repair and maintain the hardware themselves, making it an excellent choice for those who value technology that promotes self-sufficiency and sustainability.
