Cordless loudspeaker manufacturers generally show the frequency response of their products which, sad to say, does not necessarily show you a great deal about the sound quality. In order to help you make a more intelligent buying decision, I am going to explain what this specification means and the way to understand it. This ideally is going to ensure you will get the perfect cordless loudspeakers for your project. A set of cordless speakers are transmit and the reproduce an audio signal which is within the frequency response range. This range is specified by showing 2 frequencies: a lower in addition to upper frequency. For example, the lower frequency might be 20 Hz and the upper frequency 20 kHz. From this specification it appears the cordless speakers would be able to work as a set of HIFI speakers. It may seem the larger the frequency response the better the cordless speakers. That, however, might not always be. You should evaluate the specifications far more carefully in order to adequately understand them.
A set of wireless loudspeakers are going to transmit and the reproduce an audio signal which is within the frequency response range. If the frequency range is 20 Hz to 20 kHz as an example, the wireless loudspeakers can transmit all signals with a frequency higher than 20 Hz and less than 20 kHz. It may seem the greater the frequency response the better the cordless speakers. That, on the other hand, will not necessarily be the case. You have to look at the specs far more meticulously in order to correctly interpret them.
In reality, a set of wireless speakers which has a frequency response from 10 Hz to 30 kHz might actually have much lesser sound quality than a set that provides a frequency response from 20 Hz to 15 kHz. Different suppliers appear to utilize different methods in order to determine frequency response. The most common technique is to describe the frequency response as the frequency range within which the wireless speakers have quite constant sound pressure level having a greatest drop of 3 decibel (dB). Generally the drop in sound pressure level is greatest at the upper and lower frequency. Yet, the frequency response often is used to mislead buyers by way of stretching the frequency range a great deal past the range in which the cordless speakers still function correctly and in addition conceals the fact that the cordless speakers aren't linear. Preferably you should attempt to get a frequency response diagram from the producer. In this diagram, you will see the way the cordless speakers behave within the frequency response range. You can even discover any kind of peaks along with valleys the cordless speakers could have. Peaks along with valleys leads to colorization of the audio. Ideally the wireless speakers should have a constant sound pressure level inside the entire frequency response apart from the drop off at the lower and upper limit. Apart from the frequency response, a phase response chart may also say a lot about the performance in addition to quality of sound of the cordless speakers.
However, various producers push this standard to the limit and will list a maximum frequency where the wireless speakers are going to barely generate a beep any longer. In addition, merely examining these 2 figures isn't going to say a lot about the linearity of the frequency response. A full frequency response graph, however, will show whether there are any peaks and valleys and in addition show how the frequency response is to be interpreted. You may even want to ask for a phase response diagram which presents important hints concerning the quality of sound.
The frequency response of Class-D amplifiers shows the greatest change with various speaker loads due to the integrated lowpass filter that eliminates switching noise from the speaker amplifier's signal. The lowpass filter characteristic, on the other hand, heavily depends on the connected speaker load.
Some amplifier topologies provide a mechanism to compensate for variations in the amplifier gain with different loudspeaker loads. One example of these techniques makes use of feedback. The amplifier output signal following the interior lowpass is input to the amplifier input for comparison. If not developed adequately, this technique might result in instability of the amp however. Other amps employ transformers and offer outputs for various loudspeaker loads. In addition to improving upon the frequency response of the amplifier, this technique normally furthermore improves the amplifier power efficiency.
