The utility model provides a kind of vibration component of sound-producing device, and the vibration component includes vibrating diaphragm 1, the and of composite bed 2
Voice coil loudspeaker voice coil 3, as shown in Figure 1.The vibration component is configured when in sound-producing device, and the voice coil loudspeaker voice coil 3 is configured in electronic action power
Driving under produce vibration, the composite bed 2 is used to strengthen the rigidity of the vibrating diaphragm, and the voice coil loudspeaker voice coil 3 can drive the vibrating diaphragm
Vibrated with composite bed 2.The vibrating diaphragm 1 includes central part 11 and ring portion 12, and the ring portion 12 is located at the central part 11
Periphery, the composite bed 2 is attached on the central part 11.Ring portion has a good deformability, the central part and multiple
Close layer and vibration is produced under the drive of voice coil loudspeaker voice coil.
Using the connected mode for being glued fixed bonding between the composite bed 2, central part 11 and voice coil loudspeaker voice coil 3.Especially, such as
Fig. 1, shown in 2, glue groove 111 is offered on the peripheral location at the edge of the composite bed 2, the central part 11.It is described multiple
The edge of conjunction layer 2 is coated with the bonding agent 4 for composite bed 2 to be fixedly connected with voice coil loudspeaker voice coil 3 and central part 11.Above three portion
Bonding agent 4 can overflow to both sides when partial pressure closes bonding, and the glue groove 111 is used to accommodate a part of bonding agent 4.The bonding of spilling
Agent 4 can be filled in the glue groove 111.
Fig. 3,4 show a case that vibrating diaphragm 1, composite bed 2 are adhesively fixed with voice coil loudspeaker voice coil 3.The glue groove 111 can play limit
The effect of the scope of the trickling of the bonding agent 4 is made, in the case of the consumption of bonding agent 4 is standard compliant, the bonding agent 4 of spilling can
Stop being flowed to ring portion 12 or other positions under the interception function of glue groove 111.The glue groove 111 reduces bonding agent
The possibility of 4 flowings, so as to reduce the change that vibrating diaphragm is rigidly likely to occur.Those skilled in the art can be by glue groove
Position, the design of depth control rigid change of the bonding agent to vibrating diaphragm, it is also possible to play appropriate invigoration effect.Separately
On the one hand, filling to the bonding agent 4 of glue groove 111 can also form parcel form to composite bed 2, so as in strengthening vibrating diaphragm
The bonding connection reliability of center portion and composite bed 2.
When bonding assembling is carried out, the whole fringe region of composite bed 2 is possible to be each coated with bonding agent 4.Alternatively, institute
Stating glue groove 111 can also form complete annular groove, when the composite bed 2 is arranged on the central part 11, in a ring
The glue groove 111 can surround the composite bed 2 edge.In this embodiment, the glue groove can be to multiple
The bonding agent around layer everywhere is closed to play a part of to stop flowing.The glue groove of annular also can be bonding agent to composite bed
Entirety plays parcel, fixed effect, improves the reliability that composite bed is fixed on central part.
The thickness of the thinning subregion of the central part 11 of the meeting of the glue groove 111, it is preferable that the glue groove 111
/ 3rd of depth less than or equal to the thickness of the vibrating diaphragm 1.In the depth bounds, the central part of the vibrating diaphragm ensure that more
Good structural strength and reliability.
