It portion and is set on the outside of pole piece, is bonded with magnet at the top of bottom crown and positioned at voice coil opposite sides, interval is arranged above voice coil
There is the metal clips being welded in bottom crown opposite sides, top crown is welded at the top of metal clips.
Preferably, bottom crown opposite sides is both provided with lug, and metal clips opposite sides is both provided with contact ear, contact
Ear is welded on the outside of lug.
Preferably, metal clips includes square frame, and square frame surrounds a port, and top crown includes and port shape
The plate body matched, the support ear extended from plate body opposite sides, top crown is set at the top of metal clips and support ear welds
In square frame opposite sides.
Preferably, top crown opposite sides is provided through screw hole.
Preferably, square frame opposite sides, which is extended, ear.
The beneficial effects of the utility model are：The utility model discloses a kind of bone-conduction speaker, and unique assembly is arranged
Top crown is welded at the top of metal clips by structure, then metal clips is welded on above bottom crown, and pcb board is bonded in lower pole
Board bottom portion, voice coil are bonded at the top of bottom crown.Bottom crown is effectively supported fixation to metal clips, and metal clips is welded on
On top crown, effectively conduction vibration.Its is simple in structure, easy to use, sound clarity, effectively reduces the body of bone-conduction speaker
Product, to be preferably applied on compact electric apparatus.Metal clips and bottom crown are fixed by contacting ear and tab welding, bottom crown and
The cavity for accommodating internal components is formed between metal clips, effectively reduces the volume of loud speaker.The magnetic field of pole piece and voice coil is through logical
Mouth interacts with top crown, and support ear is supported top crown and as force position, metal clips is caused to vibrate, and is promoted
Metal clips induction sensitivity.Run through setting screw hole in top crown opposite sides, it is convenient that bone-conduction speaker is installed
It is fixed.Setting ear is convenient to capture loud speaker, and the crawl other components of loud speaker is avoided to lead to deformation effect performance.
