Gloture from Tokyo introduced a typewriter-like Bluetooth keyboard called the KnewKey DJ88, it's paired with JBL speakers.

The speaker has a high-quality dual-channel speaker with an S / N ratio of up to 90 dB, a 45 mm full-range unit, and a BASS radiator, and an AAC decode Bluetooth 5.0 chip + Texas Instruments digital power amplifier (TAS5825M). In addition, JBL's proprietary acoustic algorithm provides high-quality 360-degree surround sound. The key layout is US83, and the key switch is a blue axis mechanical switch with a gimmick that shines a 3D light in sync with the music and a PC stand (also compatible with smartphones and tablets). It also supports multi-pairing, which lets you connect to three Bluetooth devices simultaneously and switch between them instantaneously using function keys.

The power source includes 7.2V / 2,200mAh lithium-ion batteries for the audio and keyboard. External measurements are 346 mm in width, 233 mm in depth, and 110 mm in height, with a weight of around 2.4 kg. Be prepared to spend some cash though, the units cost 469 USD/EUR.
