In installation cavity；In 2 the two of protecgulum 1 and frame, it can be provided with connecting pole 11 in one, connecting hole can be provided in another one
21, connecting pole 11 can be mating with connecting hole 21, and connecting pole 11 can also be fixed with connecting hole 21 by bonding mode
Connection, the purpose of connection protecgulum 1 and frame 2 may be implemented in this.Certainly, can also include other component in mini-sound device,
Such as support element 6, magnetic conductive part 7 and lower clamp plate 8, details are not described herein again.
Wherein, frame 2 and protecgulum 1 can be the plastic construction that plastic material is formed through injection molding；Correspondingly, can pass through
Change the structure of corresponding mould so that connecting pole 11 and connecting hole 21 can in the forming process of protecgulum 1 and frame 2 shape together
At, and connecting pole 11 can be arranged on protecgulum 1, can also be arranged in frame 2；Connecting pole 11 can only be arranged one,
It can be arranged multiple；When connecting pole 11 and connecting hole 21 plug, suitable adhesive can be first coated in connecting hole 21,
Connecting pole 11 is fixedly connected by adhesive with connecting hole 21, and then to be fixedly connected with protecgulum 1 and frame 2.Ability
Field technique personnel can according to different actual demands, it is corresponding change protecgulum 1, frame 2, sound film 3, voice coil 4, magnet steel 5 shape
And size, to adapt to different operating scene；Sound film 3 can be made of flexible materials such as the hard materials such as metal or plastics；Voice coil 4
Can be formed through coiling by thin copper wire, and voice coil 4 can be arranged there are two connection end, both of the aforesaid connection end can with it is outer
Portion's circuit connection；Magnet steel 5 can be permanent magnet, or artificial magnet；Sound film 3 can be adhered to voice coil 4 by glue
On so that being connected with the voice coil 4 of alternating current can drive sound film 3 to vibrate in magnetic field；Magnet steel 5 can be arranged in the center of voice coil
Domain so that the magnetic field intensity at 4 each position of voice coil is of substantially equal.
It is above-mentioned it is found that in mini-sound device provided by the utility model, connecting pole 11 and connecting hole 21 plug, and two
It can also be bonded by adhesive between person, the purpose for being fixedly connected with protecgulum 1 and frame 2 may be implemented in this.Meanwhile this practicality is new
In the connection procedure of this mini-sound device that type is provided, protecgulum 1 and frame 2, protecgulum 1 and frame 2 will not be because by high temperature
And it deforms, it is clear that, this can improve the product quality of mini-sound device, can also improve user satisfaction.
Further, on the axis direction in connecting hole 21 and the direction around aforementioned axis, connecting pole 11 and connecting hole
It can be provided between 21 and hold glue gap.
Specifically, when designing connecting pole 11 with connecting hole 21, each correspondence position in connecting pole 11 and connecting hole 21 can be made
The size for setting place is different so that after the completion of connecting pole 11 and 21 grafting of connecting hole, on the axis direction of connecting pole 11 and
In the circumferential direction of connecting pole 11, still had the gap between connecting pole 11 and connecting hole 21.The assembling process of connecting pole 11 and connecting hole 21
It is as follows：Can adhesive be first filled into connecting hole 21, then connecting pole 11 can be inserted into connecting hole 21, at the same time,
Extra adhesive can overflow in calm glue gap in connecting hole 21, meanwhile, the appearance on the axial and circumferential of connecting pole 11
Glue gap can be with accommodating portion adhesive, with the face opposite with connecting hole 21 of bonding connection column 11 so that connecting pole 11 with connect
Connection between hole 21 more fastens.
Optionally, the matching relationship between connecting pole 11 and connecting hole 21 can be interference fit, this can further be carried
Connective stability between high connecting pole 11 and connecting hole 21, so that protecgulum 1 connect more secured with frame 2.
Since the thickness of protecgulum 1 is smaller compared with the thickness of frame 2, thus connecting hole 21 can be set in frame 2, accordingly
, connecting pole 11 can be set on protecgulum 1.
Specifically, connecting pole 11 can be allow to be formed directly on protecgulum 1, accordingly in the forming process of protecgulum 1
, connecting hole 21 can also directly be formed during forming frame 2；Certainly, connecting pole 11 can also it is seperated with protecgulum 1 at
Type, then connected together by adhesive etc., correspondingly, connecting hole 21 can also be formed in frame 2 by way of boring and processing
On.Wherein, preferably connecting pole 11 is integrally formed with protecgulum 1 by way of injection molding.
Further, recessed portion 20 can also be set in frame 2, connecting hole 21, protecgulum 1 can be set on recessed portion 20
It can be installed in recessed portion 20.
Specifically, the shape of recessed portion 20 can mutually be fitted with the shape of protecgulum 1, and in the injection moulding process of frame 2, Ke Yizhi
It connects to form recessed portion 20 and connecting hole 21, protecgulum 1 is mounted in recessed portion 20 so that perpendicular to the flat of 11 axis of connecting pole
In face, recessed portion 20 can play protecgulum 1 certain position-limiting action, to share the power that connecting pole 11 is born；Meanwhile by setting
Recessed portion 20 is set, the space availability ratio of frame 2 can also be improved, and then reduce the volume of mini-sound device entirety；Meanwhile
During assembly and connection column 11 and connecting hole 21, recessed portion 20 can also play auxiliary positioning.
Optionally, connecting pole 11 and connecting hole 21 can be respectively provided with multiple, and multiple connecting poles 11 and multiple connecting holes 21 can
To be arranged in a one-to-one correspondence.
Specifically, connecting pole 11 can be arranged two, three, four and more, the position of multiple connecting poles 11 can
To be correspondingly arranged according to the difference of 1 shape of protecgulum so that multiple connecting poles 11 can be more evenly distributed on protecgulum 1；Together
Sample, connecting hole 21 can also be arranged multiple, and multiple connecting holes 21 can be correspondingly arranged with multiple connecting poles 11, this can be into one
Step improves the stability of protecgulum 1 and 2 connection relation of frame.
More specifically, protecgulum 1 can be rectangle or approximate rectangular structure, and the protecgulum 1 of rectangle has corresponding four
Corner 10, correspondingly, connecting pole 11 can also be arranged four, four connecting poles 11 corresponding with four corners 10 respectively can be set
It sets；Correspondingly, frame 2 or rectangular configuration, the position of connecting hole 21 can be corresponding with connecting pole 11.Using it is aforementioned this
Kind scheme can reduce protecgulum 1 and frame while ensureing to have sufficiently stable connection relation between protecgulum 1 and frame 2
2 processing and assembling difficulty.
In order to further decrease processing and assembling difficulty, optionally, connecting pole 11 and connecting hole 21 can be cylindric
Structure.
