Cordless loudspeaker vendors typically show the frequency response of their items that, however, will not automatically show you a great deal about the audio quality. To help you make a wiser buying decision, I will explain what this specification means and how to interpret it. This ideally is going to ensure you will get the perfect wireless loudspeakers for your project.
A set of cordless speakers are transmit and the reproduce an audio signal that is inside the frequency response range. This range is specified by listing two frequencies: a lower and also upper frequency. For example, the lower frequency could be 20 Hz and the upper frequency 20 kHz. Using this specification it appears the wireless loudspeakers could function as a set of HIFI loudspeakers. You could be tempted to choose a set ofwireless speakers that offers the greatest frequency response. On the other hand, there's a lot more to knowing a cordless speakers's functionality than merely understanding this simple range.
It seems there are numerous approaches that makers employ whilst specifying the frequency response. The normal convention is to present the frequency range inside which the sound pressure level of the speakers will decrease a maximum of 3 dB from the nominal level. On the other hand, several manufacturers push this standard to the limit and may show an upper frequency where the wireless loudspeakers are going to hardly generate a beep any more. Furthermore, merely taking a look at these 2 figures is not going to say much about the linearity of the frequency response. A full frequency response graph, on the other hand, will show whether or not there are any kind of peaks and valleys and also show the way the frequency response is to be interpreted. You might also wish to request a phase response chart that also gives essential hints in regards to the sound quality.
However, the frequency response frequently is utilized to deceive buyers by way of extending the frequency range far past the range where the wireless loudspeakers still work effectively and also conceals the reality that the wireless loudspeakers may not be linear. If possible you should really make an effort to obtain a frequency response chart from the maker. In this diagram, you will see how the cordless loudspeakers function within the frequency response range. You may also discover any peaks or valleys the cordless speakers might have. You may also desire to demand a phase response chart which also offers crucial clues regarding the quality of sound.
You additionally may need to look at the conditions under which the frequency response was calculated. You usually are not going to find any kind of details about the measurement conditions, unfortunately, in the producer's data sheet. One condition which might affect the frequency response is the impedance of the loudspeaker driver built into the wireless speakers. Standard speaker driver impedances range between 2 to 16 Ohms. The lower the speaker driver impedance the greater the strain for the internal amplifier. The frequency response of Class-D amps shows the greatest change with various speaker loads because of the integrated lowpass filter that eliminates switching noise from the speaker amplifier's signal. The lowpass filter characteristic, on the other hand, greatly depends on the attached speaker load.
A few amps incorporate feedback in order to compensate for changes in gain because of different connected loads. Other amps make use of transformers and offer outputs for various speaker loads. Apart from improving upon the frequency response of the amplifier, this technique normally also improves the amplifier power efficiency.
