Pierre Le Brun Posted May 13, 2021 Share Posted May 13, 2021 I have aquired an Iphone 8 speaker and was considering using it on one of my locos. The problem I have is that it has 3 tabs for soldering. Two tabs are next to each other and a third at the opposite end of the speaker. Any idea what tabs I use for soldering?

RAF96 Posted May 17, 2021 Share Posted May 17, 2021 Possibly the third tag is to take the speaker out of circuit if an earpiece is plugged into the phone, although normally this is simply done by the jack plug. May have something to do with EMC clearance, etc. 1 Link to post Share on other sites More sharing options...
