Abstract
An analogue simulation human-head test frame is provided, which is composed of a frame and at least one artificial ear fixed on the frame; wherein the bottom plank of the frame is provided with at least one artificial mouth which is mainly made of a speaker and a shell; a pair of artificial ear are arranged on the column at the left and right sides of the frame respectively; the upper part of the columns is provided with a support block which is connected with a head-ring positioning board by an adjusting screw; the artificial ear is 318 type; a pair of guide pins are connected between the support block and the head-ring positioning block; each guide pin is provided with a spring. Compared with the prior art, the utility model has the advantages of simple structure and operation, rapid testing velocity and high degree of stability and precision of testing index.
Description
Technical field
The utility model relates to a kind of test earphone that is used for,, belong to the testing equipment field of electro-acoustic element especially with the electro-acoustic element analogue simulation number of people testing jig of microphone earphone
Background technology
In the prior art, to electro-acoustic element, particularly with the electroacoustic index of microphone earphone, testing equipment as sensitivity difference of 1K sensitivity, average sensitivity, frequency response curve, two ears etc., during its test, before this to each earphone messenger electric current, gather the voice signal that earphone sends by artitificial ear, be input to tester and carry out the test of electroacoustic index, changing testing equipment then tests microphone, the operating process of its whole test is comparatively complicated, test speed is also slow, and the result precision of test is low, and consistency of product is also bad.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, and easy and simple to handle, test speed is fast, the analogue simulation number of people testing jig that test index is stable, accuracy is high.
The purpose of this utility model is finished by following technical solution, and it mainly is made up of support and at least one artitificial ear that is fixed on the support, it is characterized in that also being equipped with on the described support at least one artificial mouth.
Described artificial mouth mainly is made up of a loud speaker and case, and artificial mouth is fixed on the base plate of support, has a pair of artitificial ear to be separately fixed on two lateral braces of support.
A piece is installed on the described pillar, and a headring location-plate links to each other with a piece by an adjustment screw.
Also be connected with a pair of pilot pin between described piece and the headring locating piece, respectively overlap a spring on each pilot pin; The artitificial ear of installing on two pillars is 318 types.
The utility model collection artitificial ear and artificial mouth are one, can once finish the test of electroacoustic index automatically to the earphone of biphone and band microphone, thereby, it compared with prior art has simple in structure, easy and simple to handle, characteristics such as test speed fast, test electroacoustic index is stable, accuracy height.
