According to the problems referred to above, designed a kind of electro-acoustic element, the vibrational system that it comprises the basin frame, is contained in the magnetic circuit system of basin frame and is immobilizated in the basin frame, described magnetic circuit system comprises the magnetic bowl with side plate, described basin frame comprise by sidewall surround the resettlement section, described magnetic bowl is positioned at described resettlement section, described sidewall comprises the inwall relative with side plate, form the gum box with certain slit between described side plate and the inwall, be provided with a narrow in the described gum box, described narrow inwall to the distance between the side plate less than other position inwalls to the distance between the side plate.
Preferably, narrow in the middle of described gum box two head breadths, described inwall comprises superposed the first inclined-plane and the second inclined-plane that is positioned at the bottom, and described narrow positions is in the intersection on described the first inclined-plane and the second inclined-plane.
Preferably, narrow in the middle of described gum box two head breadths, described magnetic bowl sidewall comprises superposed the first inclined-plane and the second inclined-plane that is positioned at the bottom, and described narrow positions is in the intersection on described the first inclined-plane and the second inclined-plane.
Preferably, described inwall is concave plane, which is provided with protuberance, consists of narrow between described protuberance and the side plate.
Preferably, described side plate is concave plane, which is provided with protuberance, consists of narrow between described protuberance and the inwall.
Preferably, described narrow is provided with the stage portion of extending to magnetic bowl direction from inwall.
Preferably, described narrow is provided with the stage portion of extending to the inwall direction from side plate.
Be provided with distance between inwall and the side plate in the gum box of electro-acoustic element of the present utility model less than the narrow at other positions, can prevent under the prerequisite that does not affect product stability and reliability that glue from flowing into interiors of products.

Fig. 2 is the cutaway view of the utility model electro-acoustic element;
Fig. 3 is the enlarged drawing of A part shown in Figure 2.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, be the three-dimensional exploded view of the utility model electro-acoustic element, electro-acoustic element 100, it comprise have by sidewall 31 surround resettlement section 30 basin frame 3, be contained in the magnetic circuit system 1 in the basin frame 3 and be immobilizated in vibrational system 2 on the basin frame 3.
To shown in Figure 3, described basin frame 3 comprises sidewall 31 and the resettlement section 30 in order to accommodate magnetic circuit system 1 that is surrounded by sidewall such as Fig. 1.Magnetic bowl 13 is positioned at described resettlement section 30.Sidewall 31 also is provided with the inwall 32 relative with magnetic bowl 13 side plates 132.Be formed for injecting the gum box 33 of glue between inwall 32 and the side plate 132.This gum box 33 is two head breadths, middle narrow structure.Concrete, inwall 32 is divided into up and down two parts, is positioned at the first inclined-plane 321 of part and 322, the first inclined-planes 321, the second inclined-plane of the latter half and forms a narrow 323 with 322 intersections, described the second inclined-plane.Spacing a in narrow is less than the spacing at other positions.The existence of narrow can effectively limit the flow velocity of glue in gum box, and then prevents that glue from flowing into interiors of products.Simultaneously, owing to only narrow in the centre, do not affect the normal input of UV light, guaranteed the rapid curing of UV glue.Certainly, this is an embodiment of the present utility model, in selectable other execution modes, inwall also can be other concave planes, which is provided with the part protuberance, this protuberance and described side plate form narrow, if in gum box, be provided with a side plate to distance between the inwall less than the narrow at other positions, play the effect of restriction glue flow velocity, namely can implement.
In selectable another kind of execution mode, also can be to have two parts in the first inclined-plane and the second inclined-plane at side plate.Certainly, side plate also can and have protuberance for concave plane, also is to play same effect.
