High efficiency audio amplifier applied in the portable devices

As the energy is intensive, electronic system gains improvement on the energy and efficiency. For the battery power supply system, the demand is harsher. With the spreading of the cheap mobile phone, mp3 and mp4 player, the audio amplifier becomes the standard configuration. No matter the system engineer or the final user will not be content with the personalized music playback.

There is higher requirement on the audio magnifier. There will less consumed current to extend the battery using time. It will improve the perfect tone quality in the whole audio range. The good radio frequency suppression ability will decrease the current voice. The stable output power will protect the audio speaker.

In the future, there will greater demand for the high efficiency magnifier. The magnifier has wide prospect in the portable device application. As to the report of Gartner, the D magnifier will grow at a rate of 15.6% rom 2006 to 2011. The main growing power comes from the portable device and consumer electronics. The mobile phone is the important growing point.

Let's introduce a high efficiency audio amplifier with latest design. The product is mainly used on mobile phones. It can provide a perfect solution with few peripheral cells. The requirements on the magnifier are small size and simple peripheral circuit.

High Efficiency

D magnifier has great advantage in efficiency. The power mainly comes from the Rdson, switch loss and resting current. The efficiency can reach 90%. It extends the battery life or the portable device.

RF Noise Control

The mobile phone, PDA and other portable communication devices can work in the poor natural condition and noisy environment. For the audio amplifier with RF interference will demodulate the RF inter-carrier massaging to the audio frequency band. There will be current voice generated on the ouput end of the speaker.

The RF signal will be coupled to the power supply, input and output end of the amplifier. The good PSRR and CMRR can lower the requirement on the PCB and structure. The 10mV output can be felt by our ear. When the power voltage is superposed the 500mV GSM signal, the output can be restricted.

Low Distortion Noise

For the audio amplifier, though the entire test index is measured by the sine wave, the final assessor is the beautiful and fluent music. The beautiful tone is decided by the harmonic distortion and noise. The ideal D magnifier is non-tatiguing. There is noise in the band.

Basics about audio integrated amplifiers and how they actually work

An integrated amplifier can sound a bit complicated to a lot of individuals, especially those who are not familiar with the basics. But the fact is that it is actually quite a simple as normal amplifiers. Consider audio integrated amplifiers as some sort of stereo receivers with no built-in radio tuners.

Basically, an integrated amplifier is a combination of typical amplifier and a preamplifier. Although a receiver allows you to connect all of your entertainment boxes such as your VCR, CD player, DVD player, game consoles, and your surround sound system, an integrated amplifier lets you connect all your electric devices for projecting as well as recording music.

An integrated audio amplifier is an electronic audio device or equipment that a lot of home music enthusiasts, professional musicians, as well as audio engineers regularly use. Since it combines features of preamplifier and an amplifier, it is actually quite convenient and easy to use. To make it more comprehensible for those who are not familiar with this type of device, we will explain what those two parts really do within the integrated amplifier.
The preamplifier is the one responsible for the reception and processing of the audio signal from the input source such as a DVD or CD player. If, for instance, the audio signal is particularly low or weak, the preamplifier adjusts the voltage to line level so that the amplifier can accurately accept the audio signal.

In addition, the preamplifier portion of the integrated amp is also where would typically input connections as well as operate controls. Every time you adjust the volume or switch program modes, you are actually operating the preamplifier portion of your integrated amplifier.

The amplifier, on the other hand, is the one responsible for amplifying the strength of the signal to significant levels, once the signal is processed and sent from the preamplifier to the amplifier. The amplifier is actually the one that will give your awesome speakers a hell of a workout. It has the capability to drive your speakers to its maximum potential.

The basic parts of an integrated amplifier are actually quite similar to receivers. Receivers are a combination of three basic components which includes an amplifier, a control center, and an AM/FM tuner.

The integrated amplifier, on the other hand, integrates a multi-channel amplifier and a preamplifier, otherwise known as a control amplifier, which is previously discussed. Integrated amplifiers usually do not have AM/FM tuners, as they are typically accompanied by a separate AM/FM tuner.

Audio integrated amps are quite rare when it comes to stereo systems. To a lot of consumers, stereo receivers, which consist of a radio tuner and sometimes a satellite radio, are more popular. However, many enthusiasts typically use separate preamplifiers and amplifiers, and separate tuners as well, if they wish to listen to the radio on their system.

Some people on the other side of the aisle do prefer integrated amplifiers over the separate ones for various reasons such as eliminating the clutter of excess connections, which can result in distortions, save some needed space, as well as cut costs on separate devices that may cause a mismatch in circuitry and design. Integrated amplifiers are mostly built for two-channel or stereo use, rather than for surround sound systems.

By planning for a highly attractive design before installing a home theater, you will be able to increase the value of your home.

Should Cars Have High End Audio Cables

For years it has been well understood in home audio that cables can have a tremendous impact on a music sound system, both good and bad. Choose the right cables and you can expect a system to come to life. Choose poorly designed audio cables, and you may forever be wondering why you can’t get your music system to come to life.

Car audio however, has been a different story. While many companies still offer coaxial interconnect cables, most have come to realize that the basic twisted pair design offers far better noise rejection in a vehicle. And then… Nothing. That’s it. Innovation seems to have hit a brick wall at the shielded twisted pair interconnect in car audio system. This begs the question; Should cars have high end audio cables?

To begin with, let’s briefly go back to home audio. After many years of fighting an uphill battle, the idea that cables make a difference has become a mainstream ideology amongst audiophiles. But it isn’t just audiophiles who can hear the difference. In fact, in our own testing, the differences can be heard by just about anybody, even on very modest audio systems. It just takes a willingness to discard any preconceived notions and actually listen to some music.

So, if cables make a difference in home audio, is there a reason why it shouldn’t matter in car audio? The quick answer is no. The following outlines some of the reasons why cables matter just as much, if not more, in car audio.

Many people are under the impression that car audio uses shorter cables than home audio system, and therefore does not need to bother with high fidelity cables. This is completely incorrect. While the typical interconnect length in a home audio system is about 1 meter, vehicles will frequently use 5 or 6 meter interconnects to put amplifiers in the trunk. In terms of speaker cables, car audio almost always uses cables longer than the 6-8 feet used in most home audio setups.

Vehicles represent a far more challenging environment for cables than home audio systems. Two typical sources of noise in cables are Electro-Magnetic Interference (EMI) and Radio Frequency Interference (RFI). In vehicles, the entire chassis is frequently used as the ground return path. This allows noise from car components such as the alternator to be inducted into the audio cables via EMI. In terms of RFI, unless proper shielding is used, the longer cables in cars will act as antennas and pull in more noise. A third source of noise in a vehicle is vibration. This is of course far worse in a vehicle than in a home system. 

Is Quality Sound Just for Home Audio or does it have a Place in Car Audio Too?

Some people feel that a car audio sound system will never be as good as a home theater audio system, and therefore high fidelity cables are a waste of money in a car music system. This is a faulty conclusion. The experience of listening to music in your vehicle while driving down the highway is unique and cannot be replicated in the home audio environment. The bottom line here is that many people spend more time listening to their car audio system than their home system, and they want it to be the best that it can be. The characteristics of bad audio cables (listening fatigue, poor realism, overly bright treble, or general noise) will all still be audible in a car audio system. Just like home audio, the wrong cables in your vehicle will kill the listening music experience.

At the end of the day, many people want quality sound in their vehicles. If you are installing an aftermarket system in your vehicle and you care about sound quality, you need to care about cables. If you are only interested in having the loudest car, without regards to accuracy, then high fidelity audio cables probably aren’t for you. Otherwise, it simply doesn’t make sense to shell out good money on amplifiers and speakers, only to hook it all up with mediocre wire.
