Abstract
The invention discloses an improved multimedia sound box listening-based sound quality detection fixture. The improved multimedia sound box listening-based sound quality detection fixture comprises a base, wherein the base is provided with two pairs of positive terminals and negative terminals; the positive terminals and the negative terminals are fixed with base screws respectively; the positive terminals are connected with a positive signal output end of a listening-based sound quality detection device; and the negative terminals are connected with a negative signal input end of the listening-based sound quality detection device. The improved multimedia sound box listening-based sound quality detection fixture applied to listening-based sound quality detection of a multimedia sound box has the characteristics of wiring stability and convenience in terminal replacement.
Description
Technical field
The present invention relates to a kind of fixture for multimedia loudspeaker box detection, more particularly, particularly relate to a kind of multimedia loudspeaker box detection fixture of improvement.
Background technology
Now, to the multimedia loudspeaker box finished product made, need just can dispatch from the factory after quality detection is qualified, in the detection that multimedia loudspeaker box is carried out, wherein comprise the detection of pure tone.Existing multimedia loudspeaker box detection fixture normally enterprise oneself is made according to actual user demand, two joint terminals all use wire to be fixed on circuit boards, circuit is in disorder, comparison is coarse, also unsightly, and be also inconvenient to change, if usually there is a terminal to damage, then need whole terminals again to connect once again, extremely lose time, also line production capacity is produced in impact simultaneously.Therefore, how being detection fixture is connected more stable with lead-in wire, changes terminal more convenient, becomes the development new direction that multimedia loudspeaker box detection fixture improves.
Summary of the invention
The object of the present invention is to provide the multimedia loudspeaker box detection fixture of improvement, wiring is stable, replacing terminal feature easily to utilize this fixture detection multimedia loudspeaker box to have.
The technical solution used in the present invention is as follows:
A kind of multimedia loudspeaker box detection fixture of improvement, comprise pedestal, wherein, two pairs of positive terminals and negative terminal is provided with at described pedestal, described positive terminal and negative terminal are fixed with pedestal screw respectively, described positive terminal is connected with the positive signal output of detection device, and described negative terminal is connected with the negative signal input of detection device.
Preferably, two described positive terminal and negative terminal are alternately arranged on pedestal in yi word pattern.
Compared with prior art, the beneficial effect that the present invention has is:
The multimedia loudspeaker box detection fixture of a modification of the present invention, comprise pedestal, wherein, two pairs of positive terminals and negative terminal is provided with at pedestal, positive terminal and negative terminal are fixed with pedestal screw respectively, positive terminal is connected with the positive signal output of detection device, and negative terminal is connected with the negative signal input of detection device.Utilize positive terminal and negative terminal to follow the lead-in wire of multimedia loudspeaker box to be connected and carry out detection detection, more stable than traditional multimedia loudspeaker box detection fixture wiring, when terminal changed by needs, as long as the screw that binding post is connected with pedestal is unclamped, just can change, replacing construction shortens greatly, thus improves production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, technical scheme of the present invention is described in further detail, but does not form any limitation of the invention.
With reference to described in Fig. 1, the multimedia loudspeaker box detection fixture of a modification of the present invention, comprise pedestal 1, wherein, two pairs of positive terminals 2 and negative terminal 3 is provided with at described pedestal 1, described positive terminal 2 and negative terminal 3 are fixed with pedestal 1 screw respectively, and described positive terminal 2 is connected with the positive signal output of detection device (not shown), and described negative terminal 3 is connected with the negative signal input of detection device (not shown).Utilize positive terminal 2 to follow the lead-in wire of multimedia loudspeaker box to be connected with negative terminal 3 and carry out detection detection, more stable than traditional multimedia loudspeaker box detection fixture wiring, when terminal changed by needs, as long as the screw that the positive terminal 2 of damage or negative terminal 3 are connected with pedestal 1 is unclamped, just can change, replacing construction shortens greatly, thus improves production efficiency.The versatility of multimedia loudspeaker box detection fixture of the present invention is high, is applicable to the multimedia loudspeaker box of the various model specification of detection.
Positive terminal 2 described in two pairs and negative terminal 3 are alternately arranged on pedestal 1 in yi word pattern, and the more convenient lead-in wire by multimedia loudspeaker box of such arrangement is connected on positive terminal 2 and negative terminal 3 and carries out detection.
The foregoing is only preferred embodiment of the present invention, all do within the scope of the spirit and principles in the present invention any amendment, equivalent to replace and improvement etc., all should be included within protection scope of the present invention.
Claims (2)
