How can I connect additional speakers to my soundbar?
With difficulty. Your sound bar does not have speaker outputs or audio outputs. That is actually the idea behind the sound bar. A piece of hardware that works on its own without the need of any extra wires and speakers.So, the only way you can connect any extra speakers to it will be by “redesigning” your sound bar or creating the outputs yourself. To do this correctly you should get the schematics of the soundbar circuit and find a point between its pre amp stage and and stage that you could use as a line level output.Another way to go about it, would be to connect the extra speakers to the existing speakers making sure you kept the correct impedance. Of course, you still need to know the circuit for the final stage of your sound bar. Your sound bar has a small woofer and tweeter on each side. It is possible it has an electronic crossover and separate amp stages for low and high frequencies, but it is also possible the woofers are working in full range and there is a small capacitor in series with the tweeter for treble, after the final amp stage.Without knowing how things are connected it is practically impossible to give you a correct answer. The possibilities are too many to consider without the correct knowledge of the circuit behind the loudspeakers.You could always try to connect a two way speaker on each side by connecting the wires leading to the tweeter in parallel or in series with the new tweeter and doing the same with the woofer trying to make sure you maintain the correct impedances.Or, if the woofer is working in full range, you could try and use a High to Low converter connected to the wires leading to the sound bar woofers.This way you would have a line level output that you could use to connect to an extra pair of active speakers or a speaker amplifier combination. But, if the woofers are not working in full range you would have only part of the frequency range with this “solution”.So, the answer to your question: ”How can I connect additional speakers to my soundbar ?”Without any further information of the electronics behind the speakers inside your sound bar, it is not possible to answer that question.Look for the service manual of your sound bar. Post it here along with the question and you may get a “better” answer.
How do ultrasonic humidifiers work?
Short answer: Ultra sonic humidifier uses ultrasonic waves to create a fine mist through cavitation in the water with a broken capillary wave at the water surface.Long answer: The humidifier consists of a piezoelectric ceramic disc which is provided with current through two nickel electrodes. Since the ceramic is piezoelectric, it oscillates in the presence of electric current at ultrasonic frequency (So you donot hear the sound waves generated in water)As the frequency of oscillation of the plate increases, water tries to follow the frequency oscillating with the plate. But water fails to match the frequency due to its inertia and weight and causes water hammers. So as the water wave lags behind the wave of the disc, an area of low pressure is created between them which forms a cavity. This is called cavitation. The cavity can be a void or filled with air since there is air dissolved in water and with the formation of low pressure, air moves into the cavity. When this cavity implodes it creates a lot of energy and the imploding jet as shown in the figure generally has a lot of energy. The vibrating disc also causes capillary waves at the surface of water (ripples). The capillary wave keeps oscillating up and down due to surface tension and gravity. With the cavity imploding, a crossed capillary wave is formed at the surface and as a result at the crest of the wave, very minute droplets of water have enough energy to break off the surface tension and get out of water. As soon as these minute drops of water exit the surface they are absorbed into the stream of air being blown by a fan and leave the humidifier as mist. The size of these aerosols would be smaller with increasing frequency. Moreover if the capillary waves are oscillating at around half of the driving frequency, the atomization threshold will be approximately linear with the viscosity of water[1].Here is a video that shows the deconstruction and parts of an ultrasonic humidifier. It has background music.http://science.discovery.com/vid... [1]http://asadl.org/jasa/resource/1...
Is it illegal to use an "electronic ultrasonic dog bark stopper" to shut up my neighbor's constantly barking mean evil dog?
Instead of trying to figure out if you can legally use a “bark stopper”, why don’t you try the unique approach of respectfully talking to your neighbor and explain that the barking is bothering you? Perhaps if you ask nicely, the neighbor might do something about it.I would be very upset if someone aimed one of those devices at my house. I have tried those ultrasonic/high-pitched noise makers for pest control and they gave me migraines. They should all be illegal. If I could not reason with the neighbor, I would start with filing a noise complaint. Please note, the authorities are not going to be willing to take a noise complaint seriously if you have not made a good faith effort at discussing the issue with your neighbor. They have better things to do.Dogs can literally smell emotions. It could be barking at you simply because you think of him as a mean, evil dog.
What all video formats are supported on DVD players and televisions which have USB ports in them?
Yeah, just like what Rory AK said, most DVD Players with USB ports can support MPEG-4/MPEG-2 video formats. And now some newer players support more video formats, like AVI, MKV, WMV, AVCHD, MPO, Xvid, DivxHD, etc. You can get such players from Amazon, such as this one Robot Check supports following formats:VideoMPEG-2/4, Xvid, MKV, HD JPEG, WMV avchd, mpo, DIVXHDAudioMP3, LPCM, WMA, AAC, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS
Hi, I'm just wondering what "Porto" means in English? I think "Porto" is a Spanish word.
"Porto's Bakery." It looks as if the Bakery belongs to Porto, more than likely the baker. "Porto" is also short for "portable" such as "portojohn" but that doesn't apply here
Why do some phone chargers make weird buzzing noises?
Mostly it is because of electricity running through it and it’s wire coils in it’s step down transformers and rectifiers . All electronics make noise just most don’t make them loud enough to hear with an unaided ear . Sometimes it is because of the wavelength they produce sound at . They do make noise none the less . The chargers that do make noise if normal may not have anything to deaden the sound radiating from them and sometimes if not normal it is because of electrical leakage shorting to ground . If a otherwise quiet charger starts to make a sounds then discharge the charger as it may be shorting inside and possibly cause a fire .
What is the formula for measuring sound?
double it by numbers cause you have two ears
