In the present embodiment, this method can be mounted in electruacousticfidelity instrument or electric sound testing system.It is using
When the loudspeaker of electruacousticfidelity instrument test product, tested product may be very poor without bluetooth or Bluetooth function module performance, but
Be most of product can all have usb debugging mouth (product usb debugging mouth be visible outside product, some product usb debugging
Mouthful be in interiors of products, it is externally invisible).
Since the electroacoustical measurement end of only a few can be by built-in interface come the order of call operation system, to pass through object
Reason connection, wireless AD B (Android Debug Bridge, Android debug bridge) directly control product.Even if can be with, realize nor
It is often difficult.In addition, since electric sound testing system is outside anechoic room, product in anechoic room, the two apart from several meters, physical connection
The problem of usb data line is too long to introduce excessive loss, lead to not communication.So by agent side as electroacoustical measurement end
With the transfer of test product.
Since test needs to carry out in anechoic chamber, so, electroacoustical measurement end is outside anechoic chamber, and test product is in anechoic chamber
Interior, the agent side as transfer is also in anechoic chamber.
For step S11, electroacoustical measurement end is instructed in response to the test that tester assigns, and is tested according in described instruction
Project, to determine corresponding basic parameter.Corresponding testing audio is generated by the basic parameter, due to test item
There are many kinds of, so, corresponding test item is determined in testing.For example, in product is tested for the first time, it is necessary to by each test
Project is all tested.At this point, the basic parameter of required determination is more, the testing audio time of generation is longer.By for the first time
After test, such as, it is determined that part electro mechanical parameter passes through, and part is obstructed out-of-date, and loudspeaker corresponding site adjusts in product
Afterwards, for the accuracy of test, it can choose each test item and all test；It may be testing efficiency, only selected that first
The project not passed through in secondary test is tested.In this way in test, tester can select accordingly according to actual needs

Distortion, difference frequency distortion is adjusted to need two-tone signal.These wave files input information certainly according to tester by electric sound testing system
It is dynamic to generate, such as the information such as start-stop frequency, frequency resolution, amplitude, minimum period number needed for the input of frequency sweep wave；Two-tone signal is defeated
Enter the information such as required frequency, amplitude.
It is bad that these electro mechanical parameters, which are used to evaluate its performance after speaker system is assembled in interiors of products, if is met
Specific to require: one, for user's sense of hearing aspect, whether the frequency response of speaker system Mid Frequency is flat, and low/high frequency playback frequency response is
No meet demand, if the problems such as introducing tremolo, abnormal sound after assembling；Two, for artificial intelligent voice interaction aspect, loudspeaker
Whether the total harmonic distortion of system, R&B are sufficiently small, if occur the problems such as mesomerism, abnormal sound, routing after assembling.Because
Total harmonic distortion and R&B is excessive or there are mesomerism, abnormal sound, routings, can all influence Speech processing algorithm performance,
Voice quality is destroyed, the experience of interactive voice is reduced, such as the problems such as wake-up rate is low, to interrupt success rate low, recognition accuracy is poor.
By analyzing these parameters, it is known that the improvement direction of product, finally promotes properties of product: such as frequency is rung
Answer, total harmonic distortion, intermodulation distortion, abnormal sound the problems such as need to improve speaker system；Tremolo, resonance, routing etc. need to improve structure
Design.
