At this stage, the test of traditional sound press is made up of product to be measured and earphone and relevant audio detection instrument
One closed circuit tests electronic product using detecting instrument while transmitting audio signal to earphone by product to be measured
Sound press data.This traditional approach is although efficient and convenient, but existing defects, because of meeting during signal is transmitted by cable
Signal decaying is generated, and traditional scheme exactly has ignored this loss value, leading to testing result, there are deviations.
It is therefore desirable to design a kind of sound press test macro, by adding 1KHz standard source of sound, earphone in a test system
And the connection circuit of audio analyzer, to measure specific loss of audio signal during being transmitted to audio analyzer
Value, then the sound press of the product of electronics to be measured is detected, solve the major technique for ignoring loss value in traditional detection mode
Problem.
Summary of the invention
To overcome the deficiencies in the prior art described above, the utility model aim is to provide a kind of sound press test macro.
In order to achieve the above objects and other related objects, technical solution provided by the utility model is: a kind of sound press is tested
System, including source of sound, switch, earphone, electronic product to be measured and audio analyzer；The source of sound passes through the first cable and described
Switch connection, the electronic product to be measured are connected by the second cable and the switch, and the switch passes through third cable and institute
State earphone connection；The switch is connected by the 4th cable with the audio analyzer, is additionally provided with electricity on the 4th cable
Hinder case.
Preferably, the resistance box is trimmable resistance case.
Preferably, the source of sound is specially 1KHz standard source of sound.
Preferably, the concrete model of the audio analyzer is U8903B, and the resistance box concrete model is UT620A.
Specific principle is as follows when in use for the sound press test macro of design described in the utility model:
The first step is first closed the switch what 1KHz standard source of sound was connect with earphone, and whole system is made to be in channel status,
1KHz standard source of sound output audio signal, be transferred to after earphone again by resistance box into audio analyzer, audio analyzer into
The reading of row signal is analyzed loss value of the signal in cable transmission process and is recorded.
Second step is again by switching to the state of electronic product to be measured and earphone connection, electronic product output signal to be measured
It is transferred to after earphone using resistance box into audio analyzer, data is read in audio analyzer.
The electronic product data that finally second step is read in audio analyzer is along with detection record in the first step
Loss value is last electronic product sound press data to be measured.
Setting resistance box is trimmable resistance case, and advantage is that resistance in resistance box can be tuned into different resistance values, in this way
It is adapted to the detection environment of different situations, guarantees going on smoothly for test macro；It can use circuit or else same resistance value simultaneously
In the environment of take multiple measurements, then be averaged, improve the accuracy of test data.
To sum up, the utility model has the following beneficial effects: the utility model by adding 1KHz standard pronunciation in a test system
The connection circuit in source, earphone and audio analyzer, to measure audio signal during being transmitted to audio analyzer
Specific loss value, then the sound press of the product of electronics to be measured is detected, it solves in traditional detection mode and ignores loss value
Technical problem underlying keeps the sound press data detected to electronic product to be measured more accurate, easy to operate, and practicability is high.
