Description
Technical field
The utility model relates to audio connector technical field, specifically a kind of audio amplifier audio connector.
Background technology
as everyone knows, multimedia loudspeaker box be exactly "
computer sound box", its main source of sound is exactly computer, this with regard to be doomed its acoustic surrounding be one near
sound field, along with the change of people's audition mode, the characteristics of demand of people to audio amplifier also changes thereupon.Most of audio amplifier is substantially all deal with the change on this type of service of multimedia computer, and done some physically to traditional prototype audio amplifier simply
change, that is: the volume of audio amplifier is reduced, loud speaker caliber size reduces power amplifier power reduction and listen to distance
shorten.After not considering these changes completely, which change is the acoustic enviroment of listening to there occurs, which sound field characteristic there occurs and which impact casing sound generating mechanism creates to closely listening to.The audio connector of existing audio amplifier, poor sealing, do not have the function of damping, result of use is poor, is easy to damage.
Utility model content
The purpose of this utility model is the audio amplifier audio connector providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of audio amplifier audio connector, comprise housing, described housing comprises left shell and right shell body, the right-hand member of described left shell is provided with projection, the left end of described right shell body is provided with groove, being connected by protruding and groove between left shell and right shell body, and be also provided with seal washer between projection and groove, the outside of left shell and right shell body is also provided with engaging lug, being connected by screw rod and bolt between the engaging lug at two ends, the outside of housing is also provided with the protective jacket between engaging lug, the right-hand member of housing is provided with input port, the inside of housing is provided with cavity, the inside of described cavity is provided with circuit board, the left end of housing is provided with output port, described output port comprises L channel output port, R channel output port and grounding ports, described output port is all connected with circuit board with input port.
As further program of the utility model: described protective jacket adopts elastomeric material to make.
As the utility model further scheme: described input port comprises L channel input port, R channel input port and input grounding port.
Compared with prior art, the beneficial effects of the utility model are: be provided with sealing ring between left shell and right shell body, sealing ring is placed in groove, after left shell and right shell body fastening, protruding top is pressed on sealing ring, because sealing ring is the structure of hollow, when pressurized, sealing ring has larger deformation, its both sides extend towards outside respectively, and contact with the inner wall sealing of groove, simultaneously, the part that both sides are out of shape is by the extruding of the inwall and convex inner walls that receive groove, the bottom of groove is filled in after making sealed ring deformation, thus make left shell and right shell body joint have higher sealing.Be provided with protective sleeve, not only increase the comfortableness of use, also there is certain damping performance, extend the useful life of jockey.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of audio amplifier audio connector, comprise housing 1, described housing 1 comprises left shell 3 and right shell body 2, the right-hand member of described left shell 3 is provided with protruding 5, the left end of described right shell body 2 is provided with groove 4, by protruding 5 and being connected of groove 4 between left shell 3 and right shell body 2, and be also provided with seal washer 6 between protruding 5 and groove 4, sealing ring 6 is provided with between left shell 3 and right shell body 2, sealing ring 6 is placed in groove 4, after left shell 3 and right shell body 2 fastening, protruding 5 tops are pressed on sealing ring 6, because sealing ring 6 is the structure of hollow, when pressurized, sealing ring 6 has larger deformation, its both sides extend towards outside respectively, and contact with the inner wall sealing of groove 4, simultaneously, the part that both sides are out of shape is by the extruding of the inwall and protruding 5 inwalls that receive groove 4, the bottom of groove 4 is filled in after sealing ring 6 is out of shape, thus make left shell 3 and right shell body 2 joint have higher sealing.The outside of left shell 3 and right shell body 2 is also provided with engaging lug 7, being connected by screw rod 8 and bolt 9 between the engaging lug 7 at two ends, the outside of housing 1 is also provided with the protective jacket 10 between engaging lug 7, protective jacket 10 adopts elastomeric material to make, not only increase the comfortableness of use, also there is certain damping performance, extend the useful life of jockey.The right-hand member of housing 1 is provided with input port 11, input port 11 comprises L channel input port, R channel input port and input grounding port, the inside of housing 1 is provided with cavity 12, the inside of described cavity 12 is provided with circuit board 13, the left end of housing 1 is provided with output port 14, described output port 14 comprises L channel output port 17, R channel output port 16 and exports grounding ports 15, and described output port 14 is all connected with circuit board 13 with input port 11.
