Lautsprecher- und Transducer-Messung

Transducer Testing Telecom transducers are very small yet important components in modern mobile phones. Best performance over a wide frequency range and as small as possible is expected. Their naturally high problem rates may result in high costs for waste goods from finished materials. Nowadays manufacturer’s increase the production yield by a 100% quality control of the individual component, the pre-assembly and finally the completed phone. Especially the PureSound Rub&Buzz test is of great help to filter out any products with abnormal noise as early as possible, thus final testing of completed phones achieves close to a 100% PASSED rate and best performance. Vibration motor testing is included! The mobile phone test adapter TA2010 or artificial ears (type IEC 318 or IEC 711) are available, which simulate the acoustical conditions at the human ear. They are typically used for mobile phone receiver testing.

Driver QC Testing Woofers with large mechanical dimensions are challenging objects for quality control. The transfer function and acoustical performance needs to be measured in axis from the front. A woofer with its big membrane area and low frequency characteristics acts more or less like a piston with very large excursions. It is obvious that manufacturing defects are most audible close to the motor itself. The front microphone inside the test box is somewhat shielded by the membrane and in some cases not very effective. With a second microphone mounted at the rear-side, any Rub & Buzz can be measured, which is not audible from the front. The offered DC resistance measurement ensures accurate Thiele/Small parameter testing for all woofer types.

Passive Speaker Cabinet Testing The basic system configuration is quickly set up and ready to go for measurements with in a few minutes. For noisy production environments an acoustically shielded test-box is recommended. The measurement microphone distance to the speaker under test is commonly equal or higher than the speaker diameter. Regardless whether it is a passive or an active system, RT-Speaker evaluates the complete performance of the system cabinet. All speakers can be tested at once or sequentially using various available test configurations. In a passive system, the impedance measurement enables RT-Speaker to record the impedance plot and identifies multiple resonance frequencies from several drivers.

Stereo TV Appliance Testing Automated testing of consumer products with multiple inputs and electrical or acoustical outputs is supported by the PureSound speaker test system. The individual acoustical performance of Left/Right speakers is typically measured in sequential order. Additional microphones or vibration sensors may probe for housing vibrations or loose grids. Input- and Output Switcher Modules may be integrated for such comprehensive matrix testing.

100V Speaker Testing The PureSound speaker test system allows impedance response- & resonance frequency testing of 100 Volt speakers, which are often used in public address systems. Lower speaker test voltages, such as 75V, 50V, 25V are also supported. In the past the speaker and the 100V transformer had to be tested separately as individual components. The complete assembly could not be tested. Assembling faults often have been detected at the actual speaker installation on-site only. The PureSound speaker test solutions offers the all-in-one solution testing the completely assembled 100V speaker with transformer. The RT-IB 100V Impedance Box enables impedance measurements up to 30 kohm, allowing to test all power-taps of a 100V speaker transformer. System includes: 1x FX100 Audio Analyzer 1x RT-Speaker Software including PureSound Rub & Buzz 1x RT-IB 100V Impedance Box 1x M2010 Measurement Microphone 1x 100V Amplifier (not scope of NTi Audio)
