MICROSPEAKER FORMED WITH CENTER CAP AND DAMPER IN ONE AND METHOD FOR MANUFACTURING MICROSPEAKER

摘要

Since the sealing machine with a center cap and an air door is used, manufacturing process is simply that manufacturing time is shortened. Meanwhile the input allowed of loudspeaker increases, high-frequency and low-the present invention relates to a micro speakers with being integrally formed an air door and manufacturing method center cap. ;According to the present invention,Provide a bracket,It includes the bracket of a cupuliform,In one bracket of a frame of its center portion,One framework,With a groove structure,It is set to the magnet and a magnetic gap of a bottom surface of bracket,It is formed between bracket and the upper end of bracket,One top plate,It forms the magnetic circuit together with magnet and bracket,One diaphragm,Its outer peripheral edge is fixed to the upper the part of the slot of framework,It is wound between the magnetic gap of spool ambient state being in,One voice coil is inserted into,One damper portion,It is used to that spool to be supported to vibrate up and down when spool,One center cap part integral of the block entrance for impurity between magnetic gap is formed,The upper part of spool and diaphragm and inner peripheral portion by an enclosed mechanism at when about central shaft vibration,It is supported on a boundary portion between dump car part and central cap portion respectively.
