Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 2, the utility model provides a kind of Minitype speaker device, and this device 100 is a kind of loud speaker modules, and it can directly apply to various electronic product as vocal structure.Concrete, this Minitype speaker device 100 comprises upper casing 10, DOME 20, vibrating diaphragm 30, centring disk 40, voice coil loudspeaker voice coil 50, mesochite 60, magnetic circuit system 70 and drain pan 80.
Concrete, centring disk 40 of the present utility model is provided with at least four electric connection points 41.Composition graphs 3, in the utility model, the planform of centring disk 40 can be determined according to the structure of voice coil loudspeaker voice coil 50.Such as, in a specific embodiment, the structure of voice coil loudspeaker voice coil 50 is oval, then centring disk 40 may correspond to and arranges an oval rubber fabric mated with voice coil loudspeaker voice coil 50, as the more intermediate annular part in Fig. 3.For convenience of the connection with voice coil loudspeaker voice coil 50, two described electric connection points 41 are preferentially located at the symmetric position of oval rubber fabric, and certainly, also can arrange multiple electric connection point 41 according to different demand, position also can be decided according to the actual requirements.
Voice coil loudspeaker voice coil 50 has at least two lead ends 51.Composition graphs 4, each lead end 51 connects an electric connection point 41.During concrete assembling, described DOME 20, vibrating diaphragm 30, voice coil loudspeaker voice coil 50 and centring disk 40 composition one vibrational structure.In the present embodiment, DOME 20 is reinforcement structures, and can be understood as is the reinforcement pad of a rigidity, when itself and vibrating diaphragm 30, voice coil loudspeaker voice coil 50 and centring disk 40 composition one vibrational structure, can reinforce this vibrational structure, improve the stability of vibrational structure.
