Specific embodiment
For technology contents, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment and match
Attached drawing is closed to be explained.
The design of the utility model most critical is: the lead of voice coil is fixed on the connection arm of force of centring disk, voice coil
It is not in the trend of relative motion during vibration, between the connection arm of force and lead, i.e., between the connection arm of force and lead not
It will appear and pull power.
Fig. 1 to Fig. 4, Microspeaker, including voice coil 2 and centring disk 3 are please referred to, voice coil 2 includes lead 6, centering branch
Piece 3 includes interior fixed part 31 and outer fixing portion 32, and interior fixed part 31 is connected with outer fixing portion 32 by connecting the arm of force 33, described to draw
The middle section region of line 6 is fixed on the connection arm of force 33.
As can be seen from the above description, the utility model has the beneficial effects that: the middle section region of the lead of voice coil is fixed on
On the connection arm of force of centring disk, for the ontology of voice coil during vibration, the arm of force can deformation occurs for connection, lead and attachment force
It is not in pull power between arm, so that the risk that lead falls off is eliminated, conducive to the steady of Microspeaker acoustical behavior is guaranteed
It is qualitative, while the generation for the case where lead is pulled apart is avoided, conducive to the service life for extending Microspeaker.
