Abstract

PURPOSE:To realize a thin-gage speaker by forming the space between the plate and the magnet forming the magnetic circuit and then storing the diaphragm into the space. CONSTITUTION:Circumference wall 18 possessing step part 20 is formed on the circumference surface of plate 17 having center pole 16. Then magnet 19 is sealed at part 20 to secure formation magnetic gap 26 around pole 16. A number of through-holes 22 are provided to magnet 19 and plate 17 for the sound discharge purpose. At the same time, diaphragm 24 having voice coil 25 plus folded part 23 at the middle part is held at its fringe part by part 20.
