Description
Technical field
The utility model relates to electroacoustic transducer field more particularly to a kind of electroacoustic transducer yokes.
Background technique
The structure of electroacoustic transducer is usually by groups such as other attachmentes such as magnet, frame mold insert washer, voice coil, vibrating diaphragm, front cover
At needing to bond together yoke ontology and magnet steel by glue during assembling.As shown in Figure 1, current electroacoustic
In converter, the bonding plane of yoke ontology 1 and magnet steel 2 is plane, and the glue amount of gluing is restricted, if glue amount is excessive, glue
Water is easy to overflow the quality that electroacoustic transducer is influenced outside bonding plane；If glue amount is very few, the bonding force between yoke and magnet steel has
Limit, reliability surplus are insufficient.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of electroacoustic transducer yoke, can increase yoke and
Bonding force between magnet steel improves reliability surplus, reduces the risk that magnet steel falls off.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows:
A kind of electroacoustic transducer yoke, including planar yoke ontology, the one side of the yoke ontology includes to viscous
The sticky bit of magnet steel is connect, setting is fluted in the sticky bit.
Further, the area of the sticky bit is equal to the area of the magnet steel, and the area of the groove is less than described viscous
Connect the area of position.
Further, the depth of the groove is 0.01-0.03mm.
Further, the groove is set to the center of the sticky bit.
Further, position corresponding with the both ends of the sticky bit is respectively set on the one side of the yoke ontology
There is a locating slot.
Further, the shape of the groove is rectangle, circle, trapezoidal or irregular shape.
The utility model has the beneficial effects that: increasing groove setting, yoke and bonding magnetic steel on the sticky bit of yoke
When, the groove can play the role of store glue, compared with the existing technology, glue-spread can greatly increase, improve yoke and
Bonding force between magnet steel provides reliability surplus, reduces the risk that magnet steel falls off, while being also avoided that glue overflows bonding
Outside face, guarantee the good quality of product.
Detailed description of the invention
Fig. 1 is the electroacoustic transducer yoke of the prior art and the structural schematic diagram of magnet steel；
Fig. 2 is the electroacoustic transducer yoke of the utility model embodiment and the structural schematic diagram of magnet steel；
Label declaration:
1, yoke ontology；11, sticky bit；2, magnet steel；3, groove；4, locating slot.
Specific embodiment
For technology contents, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment and match
Attached drawing is closed to be explained.
The design of the utility model most critical is: groove is arranged in the sticky bit of yoke.
Referring to figure 2., a kind of electroacoustic transducer yoke, including planar yoke ontology, the side of the yoke ontology
Face includes the sticky bit to adhesive magnetic steel, and setting is fluted in the sticky bit.
As can be seen from the above description, be arranged the utility model has the beneficial effects that: increasing groove on the sticky bit of yoke,
When yoke and bonding magnetic steel, the groove can play the role of storing glue, and compared with the existing technology, glue-spread can increase greatly
Add, improve the bonding force between yoke and magnet steel, reliability surplus is provided, reduces the risk that magnet steel falls off, while also can
It avoids glue from overflowing outside bonding plane, guarantees the good quality of product.
Further, the area of the sticky bit is equal to the area of the magnet steel, and the area of the groove is less than described viscous
Connect the area of position.
Seen from the above description, after on yoke, magnet steel can cover groove bonding magnetic steel, both ensure that the viscous of magnet steel
Intensity is connect, and does not influence the appearance of electroacoustic transducer after bonding.
Further, the depth of the groove is 0.01-0.03mm.
Seen from the above description, magnet steel is strongly adhered on yoke by the glue amount that the groove of the depth is accommodated enough,
The presence of the groove will not influence the original performance of yoke simultaneously.
Further, the groove is set to the center of the sticky bit.
Further, position corresponding with the both ends of the sticky bit is respectively set on the one side of the yoke ontology
There is a locating slot.
Seen from the above description, in mounting magnetic steel, two locating slots at sticky bit both ends can help operator fast
Magnet steel is placed on accurate position by speed contraposition, and it is viscous inclined to place magnet steel.
Further, the shape of the groove is rectangle, circle, trapezoidal or irregular shape.
Embodiment
Referring to figure 2., the embodiments of the present invention one are as follows: a kind of electroacoustic transducer yoke, structure mutually Nian Jie with magnet steel 2
At a part of electroacoustic transducer.
The electroacoustic transducer includes planar yoke ontology 1, and the one side of the yoke ontology 1 includes to adhesive magnetic steel
2 sticky bit 11, the interior setting fluted 3 of the sticky bit 11.The area of the sticky bit 11 is equal to the area of the magnet steel 2,
The area of the groove 3 is less than the area of the sticky bit 11.The shape of the groove 3 is rectangle, circle, trapezoidal or do not advise
Then shape.The depth of the groove 3 is 0.01-0.03mm.In the present embodiment, the groove 3 is rectangle, the depth of groove 3
For 0.01mm, it is preferred that the groove 3 is set to the center of the sticky bit 11, the i.e. center of groove 3 and the sticky bit 11
Center be overlapped.After magnet steel 2 is adhered on yoke, magnet steel 2 can cover groove 3, and a certain amount of glue can be contained in groove 3
Magnet steel 2 is strongly adhered on yoke by water.
Further, position difference corresponding with the both ends of the sticky bit 11 on the one side of the yoke ontology 1
It is provided with a locating slot 4.The distance between two locating slots 4 are equal to the length of magnet steel 2, and locating slot 4 is close to sticky bit 11
The shape at edge is identical as the shape at the edge of magnet steel 2, therefore, in mounting magnetic steel 2 on yoke, by the edge of magnet steel 2 and two
The edge of a locating slot 4 is aligned, and the rapid-aligning of magnet steel 2 can be realized.
In conclusion electroacoustic transducer yoke structure provided by the utility model is simple, can be improved between yoke and magnet steel 2
Bonding force, reliability surplus is provided, the risk that magnet steel 2 falls off is reduced, while being also avoided that glue overflows outside bonding plane, is guaranteed
The good quality of product；The rapid-aligning of magnet steel 2 can also be realized simultaneously, improve the packaging efficiency of magnet steel 2.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalents made based on the specification and figures of the utility model are applied directly or indirectly in relevant technology neck
