Want to find super small BLE speaker to fasten to bangle.js strap

Hi,

Does anyone know of a BLE speaker that would fit on a 20 mm strap? I want to connect it to the bangle and override the beep() function to use it. May be a product suggestion for the espruino shop?

Inspiration came from the subreddit: https://www.reddit.com/r/Banglejs/commen­ts/1b279gk/why_is_there_a_beep_setting_i­f_there_is_no_speaker/

What do you mean by "BLE speaker"?
Some (super small) custom device with buzzer+battery+BLE chip with some special BLE service implementing beeps?
LE Audio is not an option and typical Bluetooth speaker is not using BLE but Classic Bluetooth which is not an option too.

Something very small that could be connected to the Bangle over bluetooth and make hearable sounds. But it seems like it's a little bit pie in the sky then...

I tried to use that ~$5 amiibo nrf52832 based keychain for that but it is not very loud, there is very small buzzer inside, I even got bigger louder buzzer chips that still somehow fit inside ( "7525 Passive" from https://www.aliexpress.com/item/32864653­388.html ) but did not finish it. So with that having it on your keys could work.
