goal:

wired door bell, a signal by pressing button triggers the ring

mp3 (optional wav) shall be played

sound quality shall be good (but no need for perfect sound)

requirements for mp3 door bell:

mp3 sound is triggered by 6, 8, 12 and 16 VAC (about this range, input signal varies and is not the same) on wire coming from button (external connector)

optional wireless/bluetooth etc., if this does not effect the manufacturing costs (parts) more than e.g. 2 EUR

sound plays for about 10s (to be between 1-30s, changeable by switch of board or by sw or other solution)

optional green LED to display "operating"

optional output connector to connect additional device like LED chain (or whatever), based on 5-12 VDC

powered by 5-12 VDC (often 12 VDC is standard) (external connector)

optional battery power support (e.g. 9 VDC)(internal stored)

USB connector to computer in order to place mp3 file on device, alternatively other connection option (external connector)

loudspeaker e.g. 8 ohm 4 W (not too loud), on the device

option external loudspeaker connection, 2x for stereo

in housing to fix on wall

optional buttons on device to start/stop/forward/backward/...

optional recording on device so the user can record the mp3-file he wants to play

optional just one mp3-file on the device to be played (so no selection needed what mp3 to be played, possibly facilitates this step) and NOT multiple mp3's stored

the ringing is actually only 1x start, usually (and optionally) no triggered stop but auto stopping (after given seconds) or playing to the end of file (then the user is responsible for a short mp3 file)
