Speaker/Receiver Unit Tester
-Type BK2120NA/BK2120A2
BaKo’s New Type BK2120NA Speaker/Receiver
Unit Tester, also known as the BK2120A2, is an
upgrade of our popular BK2120A Audio Analyzer.
Our redesign of the BK2120A hardware makes it
easier to set up, and our new software interface
allows you more versatility with the same speed
and accuracy.
More versatility means that you can use
either one or two sweeps to test frequency
characteristics and Rub & Buzz. Results
appear in seconds in your choice of formats,
whether you choose to simply check whether your DUT’s pass or fail, or need more
detailed information to see exactly where any problems occur. Messages for both
passing and failing can be custom tailored so you can make testing as easy or as
sophisticated as you need, to minimize your training time, and maximize reliability.
But the core system is still the same. You can test up to 2 DUT’s simultaneously
to quickly get accurate test results on the quality of microspeakers, receivers or
earphones on your product line. With the BK2120NA, you ensure your production is
succeeding in the short term and is stable in the long term.

8 Channel Speaker/Receiver Unit Tester
-Type BK9012
The BaKo Type BK9012 fully automatic
microspeaker Test System is our fastest system for
testing your microspeakers. It can simultaneously
test up to 8 microspeakers or receivers for standard
acoustic quality and for Rub & Buzz and then sort
them into the appropriate bins.
The BK9012 Microspeaker Test System consists
of a multi-channel unit based on the BK2120A
microspeaker tester and an automatic loading
system which loads 4 or 8 couplers at a time and
sorts the DUT’s according to the results. The
potential for sheer volume of testing makes this the economical solution if your
company counts its monthly output in millions.
When you begin testing, data from the couplers is sent from the DAQ to the PC
for analysis. Although you can monitor what is happening, the PC will determine
whether the DUT’s pass or fail and sort them into the appropriate bins based on the
grade of pass or the type of failure. The results can be saved to examine current
accuracy and trends in long term stability.

Earbud Function Button Tester
-Type BK2121
We developed the BaKo Type BK2121 in
response to Apple’s need to maintain quality
control in earbuds designed to be used with
newer IPods which contain function controls
and an internal microphone.
It is a compact, easy to setup, easy to use
machine with a short test time you can use to functionally validate each earbud unit
as it comes off the product line.
Function:
You connect the BaKo Type BK2121 to the DUT through a BX6110R10 Earphone
Extension Board. It contains a chip which enables it to simulate an Apple IPod and
provides regulated downstream power to the earbud unit, as well as a microphone
bias line. It detects the mode (Button or Tone Mode) and information in both Button
Mode and Tone Mode. The chipset will also detect the model ID of the microphone
and end the test if the incorrect model is connected.
Testing:
Testing in Automatic Mode is very easy. When you connect the earbuds, the timer
starts. If it detects the wrong ID, it will automatically “Fail”. Otherwise, you’ll see the
“mic” LED light up to indicate the mic is working and the model ID appear.
After the LED goes off, you can press +, - or ► on the cable in any order. When the
machine has received all these signals it switches to Button Mode. The user again
presses the +.—and ► buttons. If the entire process ﬁnishes before the timer counts

The BK3010V2 is the new, more
versatile version of the BK3010. It
was designed and manufactured
by BaKo to test the quality of
C-microphones on the assembly
line. It is still easy to set up or to
change to a new line but also gives
the added ability to connect to a computer, see your results there, and store them to
compare with each other or over time.
We speciﬁcally designed the BK3010V2 to use on your product line, in QA or QC,
so it uses DSP (digital signal processing) to enhance both speed and accuracy.
Because of its speed, versatility and accuracy, we also used it as the basis for the
BK9010B fully automatic C-mic test system and the BaKo Type BK3012 D-mic tester.
When you test a C-mic with the BK3010V2, it measures current to determine whether
there is an open or short circuit. Then it measures sensitivity in three frequency
bands and compares these sensitivities to make a quality determination based on
the differences. Your results are displayed in a custom format on the VFD screen so
quickly, they appear instantaneous.
The BK3010V2 is also available as the BK3010V2E MEMS Mic Tester.

to test the quality of D-microphones on
the assembly line. The BK3012V2 is still
easy to set up or to change to a new line
and it gives the added ability to connect
to a computer, see your results there, and
store them to compare with each other or over time.
The BK3012V2 measures current to determine whether there is an open or short
circuit. In addition, it measures sensitivity in three frequency bands. This means
you can not only assess the sensitivity in each band, but also compare the bands
and make quality determinations based on the difference. Because of its speed
and accuracy, we used the BK3012V2 as a basis for the BaKo Type BK9013, our 8
channel, fully automatic D-Mic Test System.
Setting up the BK3012V2 is very fast and easy because you can enter the DUT
and test speciﬁcations using the simple setup menu. And if you have special
requirements, we can customize your company’s machines for you.

C-mic Tester Lite
-Type BK2011
If you use C-mics, our smallest and most
portable tester may be exactly what you
need.
Based on the BaKo Type BK3010, you can
use the Type BK2011 to measure the electric
and acoustic characteristics of C-mics.
Because it uses DSP (digital signal processing), the results are always very accurate
and almost instantaneous.
The BK2011 is so small (29cm x 26cm x 7.5cm) that you can use it almost anywhere.
And you can easily set it up in a few minutes. These two facts make it the ideal
portable tester, which you can use for spot checking, QA, QC, or even to maintain
quality as a regular product line tester.
As soon as the DUT is connected, the BK2011 starts testing automatically and
shows the test results on the VFD screen, indicating SPL of the sensitivity band,
current and capacitance (BK2011C). It will also indicate a short or open circuit.
Set up and testing are so easy that it only takes a few minutes to learn. If you need a

Remote Control Voice Recognition Tester
-Type BK3013
We designed the BaKo BK3013 Remote Control
Voice Recognition Tester to test microphones used
for voice recognition functions in television remote
controls. It uses BaKo’s familiar “Test Shop” software
in conjunction with the DAQ, making it easy to set up
and easy to use.
The BK3013 tests three properties of the remote
control functions. The Frequency Response Function
(FRF) is tested using a uniform SPL sweep generated
by the BK3013. The computer also tests Transient
Noise (TRN) and checks that appropriate RF information is received. To test for Non
Linear Processing (NLP), the BK3013 runs an SPL sweep at a single tone, which
allows you to see that the mic performs in a linear
fashion as the SPL increases.
You can enter your own speciﬁc feedback messages
for different types of results and the computer quickly
determines whether the results of both the FRF and
NLP tests fall within the limits you set and displays
either your custom message accordingly. It also
displays graphs of each test so you can see where the
DUT deviates from the parameters. Of course, you can
save the data in a spreadsheet format to evaluate at a
later time.
If you produce remote voice recognition units, the
BK3013 can help you maintain the quality you require
on your product line.
Features and Uses:

C-Mic Auto-Test System
-Type BK9010B
With the BaKo Type BK9010B Automatic C-Mic
Test System, you can test both the electric and
acoustic characteristics of up to 8 C-mics at once
to get accurate and almost instantaneous results.
The BK9010B C-Mic Test System consists of one
or two testers with couplers for 4 C-mics and an
automatic loading/sorting system which loads
couplers simultaneously and sorts the DUT’s
according to your results. The potential for sheer
volume of testing makes this the economical
solution if your company’s monthly output is in
the millions.
When the probes connect to the C-Mics on the
couplers, you can see your results on the screen almost immediately. The system
determines whether the DUT’s pass or fail and sorts them into the appropriate bin
based on the grade of pass or the type of failure. You can also save results to
analyze and to track accuracy and consistency.
If your company makes MEMS mics, consider the BK9010E MEMS Mic Test System,
a variation of the same system.

D-Mic Auto Test System
-Type BK9013
If you need a superfast, fully automatic D-Mic
Test System, try the BaKo Type BK9013. It uses
DSP (Digital Signal Processing) to measure
the electric and acoustic characteristics of up
to 8 D-Mics at once, making the results very
accurate and almost instantaneous.
The BK9013 D-Mic Test System is very easy
to use. All you need to do is pour some
microphones into the feeder and press the
“Start” button. The tester loads the mics,
performs the test and sorts them into bins
according to their passing rank or type of failure.
The entire process takes just a few seconds, meaning you can test millions of mics
per month.
The D-Mic Tester measures current to determine whether there is an open or short
circuit and also sensitivity in three frequency bands. And although you can monitor
what is happening, it is the system that determines whether the DUT’s pass or fail
based on speciﬁcations you enter after the hardware is set up.
And of course, you can save the results for analysis and to track accuracy and
consistency. If your company puts out millions of D-mics per month, the BK9013 is
the ultimate testing tool for quality control.

Silicon Microphone 8 Channel Auto Test System
-Type BK9015
If you’re making millions of mics per month, the
BaKo Type BK9015, our fully automatic MEMS
(Silicon) microphone sweep tester, is our tool
to help you keep your standards at the highest
level. It can test up to 48 mics per minute
(assuming a 10 second total test time), or over 2
million mics in a month.
The BK9015 is based on the BK3011 Audio
Analyzer, so unlike the simpler BK9010 MEMS
Mic Test System, it uses a uniform SPL sweep
test. This means you can have frequency data
such as FRF as well as current, impedance and
sensitivity over the full test range. As the data is
absolute, it’s also easy to compare to anechoic
chamber data. And the DSP (Digital Signal Processing) ensures that testing is both
fast and accurate.
Test data from the couplers is sent from the DAQ to the PC for analysis. You can
monitor what is happening but the system will determine whether the DUT’s pass or
fail and sort them into the appropriate bin based on the grade of pass or the type of
failure. You can save the results to examine the accuracy of your production process
or trends in long term product stability. The BK9015 is the ideal test solution for
companies with high volume mic production and is also available for D-Mics.

Mouth Simulator
-Type BO1032
The BaKo Type BO1032 Mouth Simulator is your
testing solution for the high quality mics you make
for modern consumer devices. Although relatively
compact and versatile, this coupler is capable of
delivering a clear constant SPL sweep that can be
used to test a mounted mic.
We built the BO1032 to be calibrated with a
measuring microphone so you can produce a
sweep with all frequencies at a given SPL. This
also means that you can consider the data from
the microphone absolute data and compare it
across couplers or to anechoic data.
The jig on top is custom made for your DUT. You can load and unload it quickly and
it will hold the mic at the MRP to receive the required tone or sweep. The jig stays
ﬁrmly in place but is easy to change. For calibration, there is a separate, specially
designed jig to hold the measuring mic in place. Preparing the coupler for a different
type of microphone is as easy as changing jigs.
The BO1032 Mouth Simulator was designed for use with the BK3011 Audio Level
Analyzer but because of its precision and versatility, you can use it as an effective
part of almost any mic test system.

Piezo Actuator Multi Tester
-Type BK2118
As piezo actuators begin replacing vibration
motors in some smart phones, BaKo has created
the BK2118 Piezo Actuator Unit Multi Tester so you
can ensure quality.
Based on the popular BK2120C, the BK2118
measures both operating and vibration
characteristics, capacitance, touch noise and
polarity. It is versatile enough to work in R&D and
QA/QC as well as on your manufacturing line.
The BK2118 allows you to run up to 4 sequences
so you can test each DUT in several different
ways. You can also enter speciﬁc PASS and FAIL messages to tell you exactly how
a DUT has performed. The DSP based BK2118 is surprisingly fast and it has two
separate channels so that you can load one jig while the other channel is testing,
saving both time and space.
With our famous “Test Shop” program, testing is easy and you can save data for your
team to analyze later. And as with all BaKo equipment, if you need a feature that is
not already packed into this versatile machine, we will modify your systems to meet
your requirements.

Vibration Unit Tester
-Type BK2020B
We developed the BK2020 to test
the RPM, current, drop pulse and
start up voltage of your cylindrical
or coin type vibration units. You
can also test vibration level, noise,
isolation resistance, and DC
resistance. It makes fast, reliable,
highly accurate measurements because it uses DSP (digital signal processing).
Although the BK2020 is completely self contained it is also very versatile: connect
it to an external speaker or to a separate device such as an oscilloscope or
spectroanalyzer to hear or see the test signal; using the LAN interface, you can
connect several BK2020’s to a controlling PC to enter DUT speciﬁcations or receive,
store and analyze all the DUT data. It even has a PLC interface for use in a fully
automatic system.
In spite of its power and versatility, the BK2020 is easy to use. The menu system is
well laid out so you can set it up in just a few minutes. The test procedure is simple
and the display is easy to understand. With all this power and simplicity, we think the

Based on the BK2019A Linear Vibration
Motor Aging Test System, we designed
BaKo’s BK2017 Linear Vibration Motor
Current and Isolation Tester to test both
current and isolation. Although designed to
give individual tests either manually or as
part of a fully automatic system, the BK2017
is also fully capable of doing aging testing as well.
The BK2017 performs two tests. Pressing the RUN button once performs the current
test. Pressing a second time performs the isolation test. It is able to test 8 DUT’s at
a time and tests all 8 simultaneously with results in 10ths of a second. Essentially, it
can test as fast as you can load the jigs.
You can buy the BK2017 as part of a fully
automatic test system, which can test your
DUT’s faster as they come off the assembly
line. Obviously, as part of a fully automatic
system, the load time decreases and it will
test even faster.

If you need to measure unbalance
in electric motors in their
housings, with speeds of up
to 10,000rpm, the BaKo Type
BK2027 Unbalance Tester may
be the machine you’re looking
for. As a 2 channel Digital Signal
Processing (DSP) based system,
the BK2027 is capable of testing 2 motors at once and displaying the balance results
as either unbalance (cm.g), acceleration (m/s2) or vibration strength (g).
You can set up the BK2027 almost anywhere as a stand-alone machine simply by
plugging in the power cable and connecting the jigs to the BNC connectors at the
front. Then use the keypad and the VFD (display) on the front panel to enter the
DUT and test speciﬁcations from the setup menu. For additional functions, you can
also link it to a PC via a LAN cable.
A PC can display or save data as it is calculated by the machine. If your company
has more than one BK2027, it can be very useful to connect several machines to a
single PC and save information for analysis later. The PC can also be used to put
the speciﬁcations into the BK2027 — useful if you want several set up the same way.
Testing
You test two motors simultaneously so begin by loading both jigs with DUT’s. Then
press a button to run the test. Both DUT’s should start and the machine will begin

Camera Barrel Motor Noise Test System
-Types BK8612
The BaKo Type BK8612 is a 2
Channel DSP based Camera
Barrel Motor Noise Test System
designed to provide the highest
quality sound and vibration testing
for your digital camera barrel DC
Motors.
The testing takes place in a semi anechoic chamber, where the camera barrel is
placed with both a microphone and an accelerometer to gather data. During testing,
the BK8612 runs a series of tests by adjusting the camera barrel using the DC Motor
and collecting data from the accelerometer and mic. The BaKo Type BK2120B DAQ
monitors both and sends the data to the PC for analysis. In the PC, the BS1123Opt006 Test Shop Program controls the test process and analyzes the data acquired.
The software performs analysis to determine the sound trend and the loudness. If
the data falls within all the parameters you entered, the DUT passes. If it falls outside
of a parameter, the DUT fails and you can easily see the reason. Passing and failing
graphs appear during testing so you can easily see the ‘shape’ of the vibrations.
Pass or fail is also shown at the top in a green or red box with the word “Pass” or
Fail” respectively.
You can set up Test Shop to save test data, which can be examined later using a
