Real fire on the fire because the speakers of good quality – speakers, powered speakers, Logitech – h
Speaker system works during a fire situation sometimes occurs. This often leads to panic the user, they are usually quickly identified as speakers of poor quality, making it very difficult to the contractor. Therefore, having a correct understanding of this phenomenon is necessary, but to help fire preventDefault. General fire subwoofer speaker speaker cone or inner flame of fire, triggering other speakers from other parts of the fire, two fire, it can also cause other fires, we begin to analyze the cause of the speaker fire. Subwoofer first unit after a fire. Speaker to catch fire because of the quality of their own is very, very good. This argument, often parties want to disagree. To do this, we must analyze the specific causes.
As the speaker himself at the end of the speaker coil, after several input-Way Electrical connections, although the turns of the coil itself is a line from beginning to end, there no <- Next Page -> interface, but the whole process of coil always drawn a line somewhere in the middle may be more evenly. So, usually when the spool of thread in a different part of the power density of the coil current with different pinout from the point of connection is likely to cause poor contact and contact with the growing resistance, the results of all these factors when added to the speaker continued the excessive power of the speaker rated to withstand the power when the speaker unit in the collapse of a weak electric circle. The fire of the speaker, power open-loop, bass will stop working. This is normal, it is intentional, will appear in the speaker, there will be a part of lack of weak ties, different parts of the electrical connections are very strong loop (because the speaker quality from start to finishing very well done), when added to electricity continues the speaker is too large, more than when the power rating of the speaker to wear, must be <- Next Page -> blown at the time that does not blow, but this time the voice coil has a very high temperature, typically up to several hundred degrees Celsius, and now some material part of the coil itself can withstand very high temperatures, there no deformation of the coil (coil, part of the deformation of the coil will collide with the magnetic coil causing damage to burn). The result of this situation Settle, continuous high-temperature voice coil for cooking cone (cone is not capable of high temperatures of Baidu), which is the reason the speakers in the fire.
Imagine if the electric loop to open the initial stroke, heat coil is not so, and no chance to cook a cone, and an excess of very strong can quickly destroy the coil of the speaker and the unit divider n ‘ is usually not caused by fire, as they may be too late to have blown hot snacks, the diaphragm tweeters are generally non-flammable, it is gene rally tweeters will not fire. Therefore, the subwoofer unit on fire, we do not make a scene, need patience to <- Next Page -> explained the owner. Followed by a divider from overheating internal speaker started a fire caused by other ingredients. In fact it is a divisor because they are very good. Who is the speaker (which includes tweeters Circle) electrical connection is open, not identified, continue to pump due to high power signal, through a divider network Crossover L / C (inductor / capacitor) is the speaker must be connected to the load to network “filter” feature, can open the entire audio band signals according to different segments assigned to the audio unit loudspeaker plays a relevant role in the distribution of the signal, if the speakers burning, electrical connections. In other words, there is no speaker crossover network load, this time will be the frequency of electrical sub-network is called “serial network step up” circuit, the output amplifier is connected to the connection of the inductor and capacitor network consisting of slots, it is <- Next -> in the audio frequency signal is displayed on the estimated impedance is very low, but not short-circuit, short, probably not trigger the amp short circuit protection measures, if the amplifier is no protection against overload, sustained strong current sent to the induction coil separation can cause fever, if the coil winding inductor and thick enough (ie, quality itself), a short time’ve never blown, then the possibility of transforming the material around it. Of course, if the inductor or capacitor is fragile, has long been a strong current of a speaker is completely destroyed, then there is no fever Crossover chances ignited.
