Furthermore, the voice coil loudspeaker voice coil extends lead and is run wires to vibrating diaphragm block.
Furthermore, the voice coil loudspeaker voice coil extension lead uses pasting protective film single-layer flexible wiring board.
Furthermore, the voice coil loudspeaker voice coil base is pressed into cloth resin pickup.
Furthermore, the vibrating diaphragm block is connected with voice coil loudspeaker voice coil by copper sheet.
The utility model beneficial effect：A kind of Microspeaker of offer involved by the utility model, due to equipped with damping
Frame, and dynamic mount can make loudspeaker not cause broken magnetic because of volume is excessive in using way, due to equipped with voice coil loudspeaker voice coil base, and
Voice coil loudspeaker voice coil base is pressed into cloth resin pickup, can make voice coil loudspeaker voice coil fixed effect more preferably, is not in that voice coil loudspeaker voice coil friction causes voice coil loudspeaker voice coil effect
Distortion, since voice coil loudspeaker voice coil both sides are equipped with vibrating diaphragm block, vibrating diaphragm block is connected with voice coil loudspeaker voice coil by copper sheet, and vibrating diaphragm block is shaken using carbon fibre mycelia
The characteristics of film, carbon fibre mycelia vibrating diaphragm is that rigidity is good, internal resistance is big, distortion is small, parsing power is high, sound exquisiteness is soft, can be by truly
The audio least bit finishes now, can not only handle tiny music detail, more can be a bit by the various audios to sound at the same time in music
Not random reduce.
