In the following paragraphs, I’m going to study if cordless outdoor speakers can provide similar audio fidelity as their corded competitors.
Cordless speakers naturally are certainly more complicated than normal loudspeakers because they integrate a cordless radio together with an audio amp. Because of this the audio fidelity of wireless loudspeakers depends on many different circumstances. To start with, the cordless broadcast has got to be top notch. The wireless broadcast of previous era wireless speakers could leave a lot to be desired. Not only does digital wireless sound achieve CD-quality audio quality but it also offers highly developed techniques for dealing with radio interference.
For efficiency reasons, a good number of present-day wireless stereo speakers utilize switched-mode audio amps (Class-D). This particular working method, however, has pretty low power efficiency. Ordinarily MOSFET transistors are utilized for this stage. The working principle of Class-D amplifiers is non-linear. The pulse-width encoder as well as the switch-mode stage induce harmonic audio distortion. More modern amps, though, continue to reduce the level of harmonic distortion. One challenge in producing cordless speakers is usually that there are several parts that need to be integrated into the speaker housing for example the cordless radio and audio amplifier. These parts are going to induce reflections of the audio waves inside of the loudspeaker. Sometimes these built-in parts may shake and tarnish the audio of the loudspeaker. A few speaker control elements like buttons plus switches require openings in the loudspeaker housing which further impact the audio.
