electrostatic speakers

1. In the boot, shutdown, restart and other operations, the speaker should be turned down to the minimum or the power off to prevent large current on the speakers caused damage. 2. Correctly set the sound card output mode. Generally we all use integrated AC97 sound cards, chassis back panel has 3 interfaces, we commonly use active speakers, so should be inserted line output interface (green), while the red

surround recordings and several commercially available dvdmovies. we also created special files for our very own matrix surround "torture" test. We began by listening to a passage from a live recording of Mahler'sSymphony No. 5. Both systems have med equally well in terms ofoverall pleasantness. however, there are some fairly audibledifferences between the two. the CS-decoded version accuratelyreproduced the original with a more diffused and spatially widersoundfield should ss t

SRS Premium Sound is a randomly attached audio software that simulates stereo surround sound on a Dell notebook. Its purpose is to provide users with good audio-visual experience. Simulate surround sound on the stereo, let the user have immersive feeling. SRS certification and Dolby certification are the development of virtual surround sound, SRS is prior to the introduction of Dolby and related certification, currently using SRS certification of the main notebook brand has Dell, Asus, Lenovo a

1, is the quality of the speaker itself, of course, when we buy speakers, some speakers of the sound quality and effect itself will have a murmur, there is an active speaker inside the amplifier, the source of noise sources can be roughly divided into electromagnetic interference, mechanical noise and thermal noise. It will increase with the amplification of the sound. So the user in the selection of

Computer speakers are one of the most important external devices for multimedia computers, especially those "enthusiasts" players are at any price to buy high-quality speakers, how to buy the sound box? Its importance indicators are mainly as follows: Frequency response The hearing range of ordinary people's ears is the 25hz-20khz sound, therefore, the frequency of the

interface with other user's system, for instance EASYJF website Open Source Forum system. The conference system temporarily uses text chat and provides voice and video interfaces. 　　 second, the technical system The server side uses the Java language and MVC uses the Easyjweb framework; The client uses AJAX technology to interact with server-side data; Conference history Information storage format uses text format to facilitate system installation and operation, but also easy to manage.

280 ℃, the gas above this temperature must take cooling measures, the gas below the dew point temperature must take temperature measures. For bag-type dust collectors, the relationship between operating temperature and dust removal efficiency is not obvious. This is different from electrostatic dust removal. For electrostatic precipitator, temperature changes will affect the dust specific resistance and ot

Original article link Poisson equation is a mathematical partial differential equation that is common in electrostatic, mechanical engineering, and theoretical physics. It is named after French mathematicians, physicists, and physicists. Poisson Equation Here, △represents the Laplace operator, while F and θ can be real or complex numerical equations on the manifold. When the manifold belongs to the Euclidean space, and the Laplace operator is usually

What's different about radiation and static electricity?Radiation is a wave, with penetrating, any heat source has a certain radiation, but the strength is different. Radiation on the human body, monitors, keyboards, mice have radiation, but the intensity is slight, as long as not long-term use, there should be no problem, if it is nuclear radiation, then will cause great harm to the human body, and even death.Electrostatic phenomenon is caused by the static electricity that the point charge int

on the circuit board, the slice capacitor can be directly attached to the component and fixed on the VCC pin. It is best to use the porcelain capacitor because the capacitor has a low electrostatic loss (ESL) and High-Frequency Impedance. In addition, the medium stability of the capacitor temperature and time is also very good. Do not use the TA capacitor whenever possible, because it has a high impedance at a high frequency. Pay attention to the fol

and the inverter, touch screen, and so on, the communication port is damaged, common damages are as follows:● R1 or R2 is burned out, and Z1, Z1, and SN75176 are in good condition. This is because there is a large transient interference current through R1 or R2, bridge rectification, Z1 or Z1 to the ground, Z1, Z2 can withstand the impact of the maximum 10A current, the transient power generated by this current on R1 or R2 is: 102 × 10 = 1000 W, which of course will be burned out.● The SN75176

) This is a test that only makes sense for smart cards and is used to check the robustness of the chip against electrostatic discharge ESD (electrostatic discharge, A 100pf capacitor is charged to ± 1500v sequentially and discharged to different contacts of the chip through a 1500 Ω throttling resistor. Because these discharges must not endanger the functions of the chip and do not change the content of t

suddenly damaged. The tool for this test is a copper plate called an electrostatic gun. The electrostatic gun is adjusted to a high voltage and low current of 10-15 kV, discharge the battery test on all metal contact points of the mobile phone at around MS-2 s and conduct the test in a room with humidity control) there will also be the same test, qualified to be released. 9. Button Life TestWith the help

the electron beam and stop it from passing through the keyhole at the end of the control gate. The lower voltage applied to the control gate only reduces the number of electrons passed. Because the intensity of the light emitted by the fluorescence layer depends on the amount of electrons in the bombardment stock, the actual light intensity can be controlled by changing the voltage of the control gate. We use graphical software commands to set the brightness level of each screen position. (Conc

EMC testing consists of 4 main items:1. ESDUsing electrostatic gun test, contact voltage ±6kv, the whole box and the internal visible metal parts are detected;Air discharge positive and negative 8KV, detection of the box and the internal metal parts (such as Board jam body), the special detection of 220V power Plug and switch place.Note: The contact discharge and air discharge test is different from the electrosta
