拆解報廢喇叭


打開喇叭外殼



喇叭 功放 變壓器


功放部分 已經沒有修理的意義



拆下來的喇叭 後來被做成這個藍芽音響

if you are to install the LTspice | Design Center | Analog Devices then DONT install it in the Windows' "Program Files" ← such will lock your files once created without allowing any further modifications to them ... instead create a new directory , say - "C:\USER\" and install it there
