Something which is worth just about nothing is the humble bluetooth speaker.  Lions have long struggled with bluetooth speakers.  There's a compromise between size, weight, & sound quality.  The best one in lion opinion was the Auvio mini.  It had the best compromises.  Its mane problem was electronicals burning out.  1st its amplifier burned out & then it had some kind of firmware corruption.

The 808 Canz 2 had good sound quality but was a brick.

The best one now might be the Anker soundcore mini.  Its sound quality is the worst & it's heavy, but it's the only thing currently made & it's just light enough.  It has better bass but is very quiet & its passive radiator breaks after 3 years.  It can be somewhat bodged with an extra op-amp & a lot of noise.  It has the most user serviceable parts.  The driver is screw mounted & removable.

The electronicals have mercifully remaned reasonably discrete & hackable.  You can normally hack them to take external 5V & automatically power up.

    Managed to combine the driver from an Anker Soundcore Mini & electronicals from an 808 Canz 2. It's not loud because it has no passive radiator. It's surprisingly sealed despite not being air tight or having any gaskets. The benefit to not having a passive radiator is it being much lighter. If the enclosure is cracked open, it sounds awful.

    A key requirement was getting it to turn on without the button. Hooking some 5V points directly to USB got it to turn on with power. To get it to pair, you have to disconnect the brown wire. Transistor power but not capacitor power causes it to pair. Of course, this also requires ungluing it. There could be an exposed jumper.

    It got a teardrop shape to more efficiently use the corner space. It has the largest possible cavity for its size. The string holes should be farther from the corner.

    There is potential in 3D printed speakers. It could possibly benefit from a transmission line but it would be heavier. Obtaining the air tight seal for a passive radiator is unlikely.

    Sadly, while the metronome was audible, music on this was hopeless so it was retired. The lion kingdom ordered another Soundcore mini on 2 week prime. When its passive radiator breaks, the 2 drivers will be made into a stereo pair.
