Fig. 1 to Fig. 9, a kind of waterproof Microspeaker, including front cover and frame are please referred to, the front cover includes annular setting
Front cover straight flange, be provided with frame groove corresponding with the front cover straight flange in the frame, the front cover straight flange with it is described
Frame groove is tightly connected.
As can be seen from the above description, the utility model has the beneficial effects that: being inserted by the front cover straight flange being arranged on front cover
To be connected and sealed in the frame groove being arranged on to frame, the front cover straight flange and frame groove of annular setting ensure that surrounding
Waterproof performance, compared with the existing technology for, the inserting mode of front cover straight flange and frame groove is lower for required precision, right
Position is more quick and convenient, to simplify process operations, while more to waterproof surface is formed between front cover straight flange and frame groove, close
Envelope property is more preferable, to reach better waterproof effect.
Further, the front cover straight flange is tightly connected by marine glue and the frame groove.
As can be seen from the above description, being sealed using marine glue, cost is relatively low, processing procedure is simple and waterproof effect is more preferable.
Further, the gap filling between the left and right sides of the frame groove and the front cover straight flange has described in one layer
Marine glue.
As can be seen from the above description, forming the sealing of twice in the left and right sides, water is at least needed across this twice marine glue,
At least water is needed to overcome gravity that could permeate into together in middle twice marine glue, difficulty is bigger, so can reach better
Waterproof effect.
Further, the gap filling between the bottom of the frame groove and the front cover straight flange has one layer of waterproof
Glue.
As can be seen from the above description, bottom is provided with three seals, at this point, water is at least needed across three marine glues,
A possibility that water penetration be further reduced to inside loudspeakers, to reach better waterproof effect.
Further, the frame groove includes opening, and the bore of the opening is sequentially increased from inside to outside.
As can be seen from the above description, frame groove includes opening, the more outside the bore of opening the bigger, to avoid in frame groove
Marine glue outside spill over outside, meanwhile, also function to the effect of auxiliary positioning.
Further, the opening is equal with the bottom width of the frame groove in innermost bore.
As can be seen from the above description, the lower half of frame groove is rectangle, convenient for assembling processing.
Further, the marine glue is solidification glue.
As can be seen from the above description, front cover straight flange is inserted into frame groove, the marine glue in frame groove is extruded
It is flowed toward two sides vertical edge, so after front cover straight flange is moved to suitable position, then solidified using solidification glue, to reach
To better waterproof effect.
Further, it is additionally provided with through-hole on the front cover, is provided in the frame one-to-one with the through-hole
Hot molten column, the hot molten column pass through the through-hole.
As can be seen from the above description, passing through the cooperation of hot molten column and through-hole, to fix front cover and frame.
Further, the through-hole is each provided with one on four angles of the front cover, and the hot molten column is in the basin
One is each provided on four angles of frame.
As can be seen from the above description, four angles are all cooperatively connected, reach better fixed effect.
Fig. 1 is please referred to figure, the embodiments of the present invention one are as follows:
