Description
Technical field
The utility model relates to a kind of electro-acoustic product, particularly the contact contacting type audio amplifier used of NB flowing water assembling work.
Background technology
The audio amplifier of conventional art adopts the connected mode of wire rod lead usually, and wiring board needs to weld together with wire rod, if the phenomenon of rosin joint, dry joint will appear in failure welding, causes and the loudspeaker loose contact.Because of having increased the weld job station, manufacturing firm's pipelining installation time prolongs simultaneously.Need during the assembling of client's streamline to be plugged on the male of coupling, lead need be fastened in mechanism's shell and fix simultaneously, manufacturer and client's assembling cycle all prolong like this, but present electronic product, shorter and shorter for the cycle request of making, fit requires more and more simple and convenient, thereby effectively reduces the production operation cost.
Summary of the invention
The purpose of this utility model is to propose the contact contacting type audio amplifier that a kind of new NB flowing water assembling work is used, and simplifies the flow process of assembling work, shortens the cycle of production operation, thereby reduces production costs.
For achieving the above object, the technical solution adopted in the utility model is a kind of contact contacting type audio amplifier, comprises spring, wiring board, back cover, cover and loudspeaker.Three of wiring board and loudspeaker and covers are injected into one, and spring and back cover are injected into one, and an end of spring adopts contact contacting type to be connected with wiring board, and the other end of spring stretches out from back cover the audio amplifier inside trumpet is communicated with external agency.
Described spring is a gold plating spring.
Described wiring board is provided with four gold plated contact A, B, C, D, and wherein two contacts of A, B are communicated with the loudspeaker internal wiring, and two contact C, D contact with gold plating spring in addition.Gold-plated spring contacts with gold plated contact, further guarantees the contact effect of contact component!
Described spring maximum outside diameter φ I has certain decrement less than the gold plated contact maximum outside diameter φ K of the wiring board that contacts with it when the box body combinations rear spring contacts with loudspeaker and outer mechanism simultaneously, to guarantee inside good contact effect is arranged.
After adopting said structure,, directly the audio amplifier inside trumpet is communicated with external agency after the casing driving fit by spring because spring adopts contact contacting type to be connected with wiring board.Three of wiring board and loudspeaker and covers are injected into one, and spring and back cover are injected into one, and what this structure shortened greatly passes through the bonding activity duration of glue, the cycle when having reduced production and assembly and the cost of the manufacturing.
For realizing the purpose of this utility model, the another kind of technical scheme that also can adopt is a kind of contact contacting type audio amplifier, comprise shell fragment, wiring board, back cover, cover, reach loudspeaker, three of wiring board and loudspeaker and covers are injected into one, shell fragment and back cover are injected into one, after the disome combination, an end of shell fragment adopts contact contacting type to be connected with wiring board, and its other end stretches out from back cover.Described wiring board is provided with four gold plated contact A, B, C, D, and wherein two contacts of A, B are communicated with the loudspeaker internal wiring, and two contact C, D contact with shell fragment in addition.Adopt this a kind of technical scheme just with the spring in the alternative last technical scheme of shell fragment, all the other structures are all identical, and its result of use can reach the flow process of simplifying assembling work equally, shortens the cycle of production operation, thus the purpose that reduces production costs.

Specific embodiments
The embodiment that provides below in conjunction with accompanying drawing describes in further detail contact contacting type audio amplifier of the present utility model.
Referring to Fig. 1,2,3,4,5, a kind of contact contacting type audio amplifier comprises spring 2, wiring board 1, back cover 5, cover 4 and loudspeaker 3.Wiring board 1 is injected into one with loudspeaker 3 and 4 three of covers, and spring 2 is injected into one with back cover 5, and disome combination back constitutes the contact contacting type audio amplifier.What this structure shortened greatly passes through the bonding activity duration of glue, reduces the cost of manufacturing.One end of spring 2 adopts contact contacting type to be connected with wiring board 1, and the other end of spring 2 stretches out from back cover 5 audio amplifier inside trumpet 3 is communicated with external agency.
In order further to guarantee the contact effect of contact component, described spring 2 is a gold plating spring.Described wiring board 1 is provided with four gold plated contact A, B, C, D, and wherein two contacts of A, B are communicated with loudspeaker 3 internal wirings, and two contact C, D contact with gold plating spring 2 in addition.Described spring 2 maximum outside diameter φ I have certain decrement less than the gold plated contact maximum outside diameter φ K of the wiring board 1 that contacts with it when box body combinations rear spring 2 contacts with loudspeaker 3 simultaneously.
After last cover 4 fuses by ultrasonic waves with back cover 5, spring 2 tightly engages with wiring board 1 liang of gold plated contact C, D, thereby reach the order ground that spring 2 connects as one inner loudspeaker 3 and external agency, realized compact conformation, interior outer contacting is good, shortened by the bonding activity duration of glue, reduced the cost of manufacturing.
Another embodiment of the utility model contact contacting type audio amplifier is referring to Fig. 6,7,8, a kind of contact contacting type audio amplifier, comprise shell fragment 2 ', wiring board 1, back cover 5, cover 4 and loudspeaker 3, wiring board 1 is injected into one with loudspeaker 3 and 4 three of covers, shell fragment 2 ' is injected into one with back cover 5, after the disome combination, an end of shell fragment 2 ' adopts contact contacting type to be connected with wiring board 1, and its other end stretches out from back cover 5.Described wiring board 1 is provided with four gold plated contact A, B, C, D, and wherein two contacts of A, B are communicated with loudspeaker 3 internal wirings, and two contact C, D contact with shell fragment 2 ' in addition.Adopt this a kind of technical scheme just with the spring in the alternative last technical scheme of shell fragment, all the other structures are all identical, and its result of use can reach the flow process of simplifying assembling work equally, shortens the cycle of production operation, thus the purpose that reduces production costs.
