The use of MEMS speakers in TWS devices came another step closer with the announcement that xMEMS has teamed up with Korean speaker vendor Bujeon Electronics.
The BEM-1xx and BEM-2xx family of speaker modules will uses a hybrid approach with a MEMS speaker as the tweeter and dynamic speaker as the woofer. It also uses xMEMS speaker amplifier but suggests that this function could also be integrated into the main SoC.
