Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Please refer to fig. 1 to 3, a micro speaker includes a frame 1 and a centering disk 2, a first pad 3 is disposed on the frame 1, the centering disk 2 includes a main body 4 and a connecting arm 5 connected to each other, the connecting arm 5 is far away from one end of the main body 4 is disposed with a second pad 6 matched with the first pad 3, a retaining wall 7 is disposed on the frame 1, a notch 8 is disposed on the retaining wall 7, a glue containing groove 9 is disposed at the bottom of the notch 8, the first pad 3 is disposed on one side of the retaining wall 7 far away from the main body 4, and the connecting arm 5 passes through the notch 8.

From the above description, the beneficial effects of the present invention are: when basin frame 1 and centering branch piece 2 bond, barricade 7 can play the effect of blockking to the glue of overflow, and simultaneously, the glue that overflows along 5 length direction overflows can be acceptd to the glue groove 9 of appearance of 8 bottoms in breach, under the mating reaction between them, glue will be difficult to flow on first pad 3, thereby prevent effectively that first pad 3 from being covered by the glue solution, and then prevent first, the rosin joint phenomenon appears in the two pads, do benefit to the structural stability and the job stabilization nature that improve micro speaker, and do benefit to the life who prolongs micro speaker.

Further, a space is arranged between the glue accommodating groove 9 and the first bonding pad 3.

As can be seen from the above description, such an arrangement can further ensure that the first pad 3 is not covered by the glue.

Furthermore, barricade 7 is the L style of calligraphy, breach 8 is located the corner of barricade 7.

As can be seen from the above description, the retaining walls 7 on both sides of the notch 8 can block the glue solution well, and meanwhile, the glue accommodating groove 9 has a large area enough to accommodate a large amount of glue solution, thereby further preventing the glue solution from flowing onto the first pad 3.

Further, the basin frame 1 is provided with a surrounding edge 10, and at least one end of the retaining wall 7 is connected with the surrounding edge 10.

Furthermore, two ends of the retaining wall 7 are respectively connected with the surrounding edge 10.

As can be seen from the above description, the first bonding pad 3 is located in a relatively closed environment, so as to ensure that the glue solution does not flow onto the first bonding pad 3, which is beneficial to improving the structural stability of the micro-speaker.

Further, be equipped with surrounding edge 10 on the basin frame 1, the one end of barricade 7 is connected surrounding edge 10, breach 8 is located barricade 7 with the junction of surrounding edge 10.

As can be seen from the above description, the manufacturer can set the specific position of the notch 8 according to actual needs.

Further, the glue accommodating groove 9 comprises a base portion 11 and an extending portion 12 which are communicated, the base portion 11 and the notch 8 are correspondingly arranged, and the extending portion 12 is far away from the first bonding pad 3.

As is apparent from the above description, the provision of the extension portion 12 can increase the capacity of the glue-accommodating groove 9.
