The utility model content
The utility model provides a kind of speaker unit for above deficiency technical problem to be solved, and this speaker unit not only volume is small and exquisite, and with being connected firmly of external circuit, reliability is high, long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of speaker unit, comprise the first housing and the second housing that combine, and contain loudspeaker monomer in the cavity that described the first housing and the second housing surround; Described speaker unit also comprises be used to the coupling assembling that is electrically connected described loudspeaker monomer internal circuit and external circuit, described coupling assembling comprises the conducting strip that is injected into one with described the second housing, and by the spring that electric conducting material is made, pass through the electric conducting material secure bond between described conducting strip and the spring.
As a kind of improvement, described electric conducting material is conducting resinl.
As further improvement, described conducting strip comprises at least two conduction sheets, and each described conduction is propped up sheet and all is combined with a described spring.
As further improvement, described conducting strip comprises four conduction sheets, and each described conduction is propped up sheet and all is combined with a described spring.
The beneficial effects of the utility model are: the coupling assembling that be used for to be electrically connected loudspeaker monomer internal circuit and external circuit of speaker unit described in the utility model comprises with the second housing and is injected into the conducting strip of one and the spring of being made by electric conducting material, between conducting strip and the spring by the electric conducting material secure bond.Because the conducting strip that the utility model is used with the second housing is injected into one has formed the coupling assembling that is connected with external circuit with spring, spring not only cost is low, and volume is little when having guaranteed bonding strength, easy to connect, can be accommodated in the first housing and the second housing, satisfy the small and exquisite frivolous requirement of speaker unit; Again owing to passing through the electric conducting material secure bond between spring and the conducting strip, in conduction, guaranteed the bonding strength between spring and the conducting strip, solved the problem of speaker unit internal circuit and external circuit loose contact, thereby improved the serviceability of speaker unit, improve functional reliability and the stability of speaker unit, prolonged the useful life of speaker unit; Simultaneously also so that the speaker unit packaging technology is simple and easy to operate.
Because electric conducting material is conducting resinl, conducting resinl has function bonding and conduction simultaneously, and the conducting resinl bonding process is simple to operation, can shorten the processing duration, enhances productivity.
In sum, the utility model speaker unit has solved the technical problem of speaker unit internal circuit and external circuit loose contact in the prior art.Have volume frivolous, functional reliability and stability are high, the advantages such as long service life.

Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.
Shown in Fig. 1, Fig. 2 and Fig. 3 were common, a kind of speaker unit comprised in the cavity that the first housing 11 of combining and the second housing 12, the first housings 11 and the second housing 12 surround containing loudspeaker monomer; Speaker unit also comprises for the coupling assembling that is electrically connected loudspeaker monomer internal circuit and external circuit, coupling assembling comprises the conducting strip 32 that is injected into one with the second housing 12, and the spring 31 of being made by electric conducting material, spring 31 connects external circuit, and the first housing 11 is provided be used to the through hole of accommodating spring 31; Be coated with between conducting strip 32 and the spring 31 and be useful on the conductive adhesive layer 33 that conducting strip 32 and spring 31 are fixed as one.Because the conducting strip 32 that the utility model is used with the second housing 12 is injected into one has formed the coupling assembling that is connected with external circuit with spring 31, spring 31 not only cost is low, and volume is little when having guaranteed bonding strength, easy to connect, can be accommodated in the first housing 11 and the second housing 12, satisfy the small and exquisite frivolous requirement of speaker unit; Again owing to scribbling conductive adhesive layer 33 between spring 31 and the conducting strip 32, conducting resinl has function bonding and conduction simultaneously, in conduction, guaranteed the bonding strength between spring 31 and the conducting strip 32, solved the problem of speaker unit internal circuit and external circuit loose contact, thereby improved the serviceability of speaker unit, improve functional reliability and the stability of speaker unit, prolonged the useful life of speaker unit; The conducting resinl bonding process is simple to operation, can shorten the processing duration, enhances productivity.
Conducting strip 32 comprises four conduction sheets 321 altogether according to the needs of circuit in the present embodiment, each conduction sheet 321 all is connected with a spring 31, conductive adhesive layer 33 is applied between each conduction sheet 321 and the spring 31, the side that the second housing 12 is positioned at conducting strip 32 is provided with for four springs, 31 separated four groove structures, can prevent that four springs 31 from coming in contact and damage circuit, can improve the stability of speaker unit; Number of openings on the first housing 11 is consistent with the quantity of spring 31, is similarly four, and the shape of through hole and big or small suitable with spring 31, can play protection and buffer action to spring 31.Four conduction sheets 321 that arrange in the present embodiment are in order to simplify circuit in conjunction with four springs 31, so that the processing of circuit board is more easy, its practical two effects that a conduction sheet can play to be electrically connected vibrational system and external circuit in conjunction with two springs equally, because the structure of circuit board is not invention main points of the present utility model, those skilled in the art can determine the quantity that conduction is propped up sheet and spring easily according to the introduction of the present embodiment and the structure of used circuit board, and this no longer describes in detail again.
The present embodiment has been set forth the mode that conducting strip 32 and spring 31 is fixed combination with conducting resinl, electric conducting material also comprises some metal materials in fact, if electric conducting material is selected metal material, just need by welding manner (for example: spot welding or thermofussion welding) conducting strip 32 and spring 31 secure bond to be in the same place.Owing to the mode technique that conducting resinl is bonding is simple to operation, can shorten the processing duration, enhance productivity, therefore be optimal way of the present utility model; Welding manner also is the conventional customary means of this area, therefore just no longer describe in detail at this.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection range of the present utility model.
