Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
Each embodiment of the present utility model is explained in detail.But, those of ordinary skill in the art
Being appreciated that in each embodiment of this utility model, in order to make reader be more fully understood that, the application carries
Many ins and outs are gone out.But, even if there is no these ins and outs and based on following embodiment
Many variations and amendment, it is also possible to realize the application each claim technical scheme required for protection.
First embodiment of the present utility model relates to a kind of circuit board assemblies.As in figure 2 it is shown, circuit board
Assembly includes circuit board 1, an at least electric-conductor 2, loudspeaker 5 and is fixed on circuit board 1 and for holding
Put the sound cavity shell 3 of loudspeaker 5.
Sound cavity shell 3 is arranged at circuit board 1, and forms sound chamber cavity with circuit board 1；Loudspeaker 5 are arranged
In circuit board 1 and be positioned at sound chamber cavity.Electric-conductor 2 includes steel disc 21 and at least a connection piece 22.
Steel disc 21 is arranged at the outer surface of sound cavity shell 3, and higher than loudspeaker 5；One end of connector 22 wears
In sound cavity shell 3 and be contacted with steel disc 21；The other end of connector 22 is held in circuit board 1.Sound chamber shell
Body 3 is formed by in-mould injection with steel disc 21, to facilitate processing.
It is also preferred that the left sound cavity shell 3 has groove, steel disc 21 is arranged in groove, steel disc 21 and sound chamber
The outer surface of housing 3 maintains an equal level, and in the case of ensureing that sound cavity shell 3 has sufficient intensity, subtracts as far as possible
Few sound cavity shell 3 and the gross thickness of steel disc 21, to avoid increasing the integral thickness of electronic equipment.Certainly,
In actual application, electric-conductor 2 can also be formed in one, and a part for electric-conductor 2 is arranged at sound chamber shell
The outer surface of body 3 and higher than loudspeaker 5, another part and can be held in circuit board 1 through sound chamber.
It should be noted that in the present embodiment, connector 22 can be elastic top pin, this elasticity
Thimble paster is installed on circuit board 1.Such as, elastic thimble is installed on by surface mounting technology laminating
Circuit board 1.The bottom of elastic thimble can be held in the lower surface of circuit board 1 as shown in Figure 2, certainly,
In actual applications, it is also possible to be held in the upper surface of circuit board 1 or be held in the inside of circuit board 1.
In present embodiment, circuit board assemblies can also include sealing member 6；Sealing member 6 is held on loudspeaker
Between 5 and housing, and around sound mouth.What sealing member 6 can make loudspeaker 5 goes out audio fruit more preferably,
The moisture outside sound cavity shell 3 can also be prevented and corrode loudspeaker 5.
It is noted that the electric-conductor 2 in present embodiment can be one or more, and, lead
The quantity of electricity part 2 is the most, and the ability of circuit board assemblies guiding electrostatic is the strongest.When electric-conductor 2 includes steel disc
21 and during connector 22, steel disc 21 and connector 22 can be the relation of one-to-many, i.e. lead for one
Only one of which steel disc 21 in electricity part 2, but have multiple connector 22；Steel disc 21 and connector 22 also may be used
Think man-to-man relation, i.e. only one of which steel disc 21 and a connector 22 in an electric-conductor 2.
But connector 22 contacts with steel disc 21, sound cavity shell 3 must be passed, say, that sound cavity shell 3
Can have the through hole corresponding with connector 22 quantity.
In terms of existing technologies, it is arranged at the appearance of sound cavity shell 3 due to a part for electric-conductor 2
Face and higher than loudspeaker 5, so the electrostatic outside sound cavity shell 3 can first contact this partially electronically conductive part 2, thus quilt
It is directed directly to circuit board 1.Further, another part of electric-conductor 2 through sound cavity shell 3 and is held in
Circuit board 1, the electrostatic of sound intracavity can be contacted with another part of electric-conductor 2, thus be channeled directly into
Circuit board 1.That is, will not during being directed to circuit board 1 due to the electrostatic inside and outside sound cavity shell 3
By loudspeaker 5, so not interfering with the performance and used life of loudspeaker 5.
Second embodiment of the present utility model relates to a kind of circuit board assemblies.Second embodiment and
One embodiment is roughly the same, is in place of main difference: in this utility model the first embodiment,
Connector 22 is elastic thimble；And as it is shown on figure 3, in this utility model the second embodiment, connect
Part 22 is spring.
For present embodiment, spring one end is contacted with steel disc 21, and the other end is fixed on circuit board 1.
Wherein, spring can be by being fixedly welded on circuit board 1, it is, of course, also possible to there are other fixed forms,
Do not repeat.Spring can be fixed on the upper surface of circuit board 1, it is also possible to sets on the circuit card 1
Putting a connection post, the end thereof contacts of spring is in steel disc 21, and the other end is sheathed on connection post, to prevent
Spring departs from steel disc 21 when being compressed.
It is also preferred that the left circuit board assemblies also includes that spring shim 4, spring shim 4 are arranged at sound cavity shell 3
And between steel disc 21, and it is sticked in spring, to prevent spring from departing from steel disc 21, thus the most really
Protect the conductive stability of electric-conductor 2.
This utility model the 3rd embodiment relates to a kind of electronic equipment, and electronic equipment includes: first implements
Mode or the circuit board assemblies of the second embodiment.
It will be understood by those skilled in the art that the respective embodiments described above are to realize this utility model
