Description
Technical field
It the utility model is related to a kind of test sensitivity of microphone microphone position-limit mechanism.
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.To microphone spirit
It is quick when being tested, microphone need to be limited on the test piece with sound source, then by tester to the sensitive of microphone
Degree is tested.Process is relatively complicated when prior art limits the position of microphone to be measured, is easily made in continuous flow procedure
Into operating personnel's fatigue, cause to reduce production efficiency.
Utility model content
The purpose of this utility model is to provide a kind of test sensitivity of microphone microphone position-limit mechanism, the conjunction of its structure
Reason, the position of microphone to be measured can be quickly limited, it is simple to operate effective, so as to improve production efficiency.
The utility model wants spacing microphone to be measured also to include the plate-like piece with microphone one, in test process
In, the position of microphone and plate-like piece need to be limited simultaneously, the sensitivity of microphone can be tested.
To achieve the above object, the technical solution of the utility model is a kind of test sensitivity of microphone microphone of design
Position-limit mechanism, including jig platform and microphone test piece, the microphone test piece are parallel to each other spacing provided with two pieces
Baffle plate, two pieces of postive stop baffles are arranged at intervals, and are provided with breach in the middle part of one of postive stop baffle, and the indentation, there is provided with microphone
Stopper slot, the spacing trench bottom of the microphone are provided with sound source hole, sound source are installed in the sound source hole；Above-mentioned jig platform, which is provided with, to be surveyed
Test piece stopper slot, above-mentioned microphone test piece insertion is described to be tested in piece stopper slot.In such scheme, microphone is tested into piece
In the test piece stopper slot of embedded jig platform, the position of microphone test piece is limited by test piece stopper slot；Above-mentioned and Mike
The plate-like piece of wind one is located between two pieces of postive stop baffles of microphone test piece, and limits plate-like piece by two pieces of postive stop baffles
Position, while microphone is located in microphone stopper slot, and the sound source hole of the microphone spacing trench bottom of face microphone down.
By using such scheme, the position that can limit microphone to be measured is once placed, it is simple to operate effective, so as to improve production effect
Rate.
Preferably, the microphone test piece and test piece stopper slot are provided with corresponding bolt hole, microphone test piece
It is bolted to connection with test piece stopper slot.By using such scheme, make the position of microphone test piece more firm,
So that position during microphone test to be measured is accurate.
Preferably, the sound source hole is circular configuration.By using such scheme, make sound source hole and microphone profile to be measured
Adaptation, is advantageous to accurately test.
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, the utility model wants spacing microphone to be measured also to include the plate-like piece with microphone one,
In test process, the position of microphone and plate-like piece need to be limited simultaneously, the sensitivity of microphone can be tested.In order to limit
Fixed position of such microphone in measurement sensitivity, the utility model provide a kind of test sensitivity of microphone and limited with microphone
Position mechanism, including jig platform and microphone test piece 1, the microphone test piece 1 are parallel to each other spacing provided with two pieces
Baffle plate 2, two pieces of postive stop baffles 2 are arranged at intervals, and the middle part of one of postive stop baffle 2 is provided with breach, and the indentation, there is provided with wheat
Gram wind stopper slot 3, the bottom of microphone stopper slot 3 are provided with sound source hole 4, installation sound source in the sound source hole 4；Above-mentioned jig platform
Test piece stopper slot is provided with, above-mentioned microphone test piece 1 is embedded in the test piece stopper slot.In such scheme, by wheat
Gram wind test piece 1 is embedded in the test piece stopper slot of jig platform, and the position that microphone tests piece 1 is limited by test piece stopper slot
Put；The above-mentioned plate-like piece with microphone one is located between two pieces of postive stop baffles 2 of microphone test piece 1, and by this two pieces limits
Position baffle plate 2 limits the position of plate-like piece, while microphone is located in microphone stopper slot 3, and microphone face microphone down
The sound source hole 4 of the bottom of stopper slot 3.By using such scheme, the position that can limit microphone to be measured, operation letter are once placed
It is single effective, so as to improve production efficiency.
For make microphone test piece 1 position it is more firm, above-mentioned microphone test piece 1 and test piece stopper slot are provided with pair
The bolt hole answered, microphone test piece 1 and test piece stopper slot are bolted to connection；The program can make microphone to be measured
Position during test is accurate.
In addition, in order to improve the accuracy of test, above-mentioned sound source hole 4 is arranged to the circle with microphone external shape fits to be measured
Shape structure.
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.
