Description
Technical field
It the utility model is related to a kind of test sensitivity of microphone operation frock.
Background technology
Sensitivity of microphone refers to that microphone exports the size of electric signal under the sound effect of some strength, and sensitivity is got over
Height, represents the acoustic-electric high conversion efficiency of microphone, and the reaction to faint sound signal is sensitiveer.Because sensitivity of microphone is anti-
An important indicator of microphone property is reflected, therefore microphone is both needed to carry out sensitivity test before dispatching from the factory.Prior art is right
Microphone is sensitive when being tested, and handheld test pen is needed, on the both positive and negative polarity that both positive and negative polarity is correspondingly pricked to microphone.This mode is imitated
Rate is extremely low, requires higher to operating personnel's proficiency, and operating personnel's fatigue is easily caused in continuous flow procedure.
Utility model content
The purpose of this utility model is that providing a kind of test sensitivity of microphone operates frock, and its is rational in infrastructure, behaviour
Make simply, to avoid because personal gimmick difference causes test data inaccurate, and reduce the labor intensity of operating personnel, so as to
Improve production efficiency.
To achieve the above object, the technical solution of the utility model is that a kind of test sensitivity of microphone of design uses operative employee
Dress, including support, the support are provided with two vertical guide pillars, the support being fixed on support are provided between two guide pillars
Plate, action bars is hinged with the supporting plate, the action bars is connected with the elevating lever being vertically arranged by connecting rod, and described connecting rod one end is hinged
Action bars, the other end are hinged elevating lever；The lower end of the elevating lever is provided with installing plate, and the installing plate is provided with two linear axis
Hold, two linear bearings are set with above-mentioned two guide pillars, and the lower surface of the installing plate is provided with needle plate, on the needle plate
Provided with vertical flexibility test pin.In such scheme, microphone to be tested is fixed on to the underface of flexibility test pin, by
Operating personnel drive action bars action, action bars by connecting rod drive elevating lever up and down move along a straight line, while installing plate also along
Two guide pillars smoothly move along a straight line up and down, so as to drive the flexibility test pin on needle plate to act, by under flexibility test pin and its
The microphone of side is contacted and tested.It is simple to operate by using such scheme, avoid because personal gimmick difference causes to survey
It is inaccurate to try data, and reduces the labor intensity of operating personnel, so as to improve production efficiency.
Preferably, the supporting plate is provided with postive stop baffle, and the postive stop baffle is provided with through hole, and above-mentioned elevating lever is arranged in
The through hole, the elevating lever are provided with the baffle ring above postive stop baffle.In such scheme, elevating lever is moved downwardly to
It is blocked during specified location, now flexibility test pin contacts with microphone, by using such scheme, personnel behaviour easy to operation
Make.
Preferably, the action bars is provided with operation handle.By using such scheme, personnel easy to operation hold operation
Bar.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and can not limit protection model of the present utility model with this
Enclose.
The utility model specific implementation technical scheme be：
As shown in figure 1, a kind of test sensitivity of microphone operation frock, including support, the support are perpendicular provided with two
Straight guide pillar 1, the supporting plate 2 being fixed on support is provided between two guide pillars 1, action bars 3 is hinged with the supporting plate 2,
The action bars 3 is connected with the elevating lever 5 being vertically arranged, one end hinge operation bar 3 of connecting rod 4, the be hinged lifting of the other end by connecting rod 4
Bar 5；The lower end of the elevating lever 5 is provided with installing plate 6, and the installing plate 6 is provided with two linear bearings 7, two linear bearings 7
It is set with and needle plate 8 is installed in above-mentioned two guide pillars 1, the lower surface of the installing plate 6, the needle plate 8 is provided with vertical bullet
Property testing needle 9.In such scheme, microphone to be tested is fixed on to the underface of flexibility test pin 9, driven by operating personnel
Dynamic action bars 3 acts, and action bars 3 drives elevating lever to be moved along a straight line about 5 by connecting rod 4, while installing plate 6 is led also along two
Post 1 smoothly moves along a straight line up and down, so as to drive the flexibility test pin 9 on needle plate 8 to act, by flexibility test pin 9 and below
Microphone contact and tested.It is simple to operate by using such scheme, avoid because personal gimmick difference causes to test
Data are inaccurate, and reduce the labor intensity of operating personnel, so as to improve production efficiency.
In addition, above-mentioned supporting plate 2 is provided with postive stop baffle 10, the postive stop baffle 10 is provided with through hole, and above-mentioned elevating lever 5 is worn
Located at the through hole, the elevating lever 5 is provided with the baffle ring 11 positioned at the top of postive stop baffle 10.In such scheme, work as elasticity
When testing needle 9 contacts with microphone to be tested, prevent elevating lever 5 from moving downward with baffle ring 11 and postive stop baffle 10, keep away
Exempt from the position that operating personnel's moment observes flexibility test pin 9, and flexibility test pin 9 has certain elasticity, prevents elastic survey
Test point 9 damages microphone when being contacted with microphone to be tested.
Action bars 3 is held for ease of operating personnel, aforesaid operations bar 3 is provided with operation handle.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as the scope of protection of the utility model.
