Piezoelectric ceramic speaker reliability life tester
With electro-acoustic devices testing requirements more perfect, CSI's engineers are constantly developing new products to better suit the needs of the market! Recently introduced a ZC1681B-A piezoelectric ceramic speaker life tester! To better meet the needs of the piezoelectric ceramic loudspeakers life test. The instrument is simple and convenient operation, especially for (mobile phone, MP3, laptop computers, PDAs and other piezoelectric speaker) R & D and QC departments manufacturers use to better assess the quality of products, automatically record the expiration time, no one can duty of long-term trial.

Currently the speaker on the market are generally aging life tester + amplifier from a combination of sources, has been unable to meet the increasingly stringent product quality testing requirements, and generally do not have the following test requirements and conditions:
1 displays the current value of the brightest speakers in real time
2 displays the real-time voltage brightest speakers
3 displays the brightest speaker impedance RMS
The display real-time capacitance values brightest speakers
Sine 5 autologous source can not produce a variety of frequency, square wave, etc.
6 not accurately display settings aging test of time, you can not record the state of the device under test. (Open, short, or too high impedance)
Six or more precisely by the user must be a basic requirement! However, according to market research, often do not have the tester made in the above conditions!
Changzhou CSI Instrument Co., Ltd. launched the latest ZC1681B-A loudspeaker life tester, in addition to fully equipped with more than six of its present requirements, as well as a number of the following features and benefits:
One, ZC1681B-A loudspeaker life tester is dedicated to the piezoelectric ceramic speaker rated power test, or the maximum power tests, the instrument with Chinese / English user interface (the factory setting is good). Functional test can be done as follows:
1) Rated noise power
2) Rated sinusoidal power
3) Long-term maximum power (requires external ZC6221 programmable noise signal / digital filter)
4) Short-term maximum power (requires external ZC6221 programmable noise signal / digital filter)
5) Custom intermittent test
Second, the testing process can be fully automated determination speakers (or headphones) with or without break. When a situation occurs when disconnected, ZC1681B-A road test immediately displays the time by the horn being broken, and also to stop the operation of the Road. The rest of the road is not yet broken continue testing until a break occurs.
Three, when all channels are used horn broken, even if less than the total test time, ZC1681B-A will automatically cease to function, and there is a flashing prompt inform testers. During testing, the instrument displays the following data measured in real-time speaker:
1 brightest speakers in real time the current value
2 brightest speakers in real-time voltage value
3 brightest speaker resistance (impedance) value (in the above functions can switch during the test)
4.-aging products can always see the test of time
Four, the measured electro-acoustic devices can automatically cut off the signal after the damage, stop the test, to avoid damage to the power amplifier can be precisely controlled trials off the automatic time recording device under test status ..
Fifth, the testing process can be connected via the instrument's RS232 port and the computer behind the test results can be stored in the computer, you can call at any time.
Six, in case of a power outage, ZC1681B-A may continue to test aging after utility power is restored.
Seven, built-in variety of signal sources :( line with China, Japan, Germany, Britain, the United States and other countries GB, MP3 directly available)
Eight, the unique pair of piezoelectric ceramic speaker impedance and the aging of the piezoelectric chip capacitance changes can be monitored.
