Current cordless speakers will naturally squander some amount of power they use up. Selecting set of wireless speakers with high power efficiency may lower the level of squandered power. I'll show you several little-known details about power efficiency to help you get the best type.
Low-efficiency types require more overall energy to output the identical level of audio power as high-efficiency products. Thus they require a larger power source which makes the wireless speakers costlier to make. In addition, due to the large amount of heat, there will be significantly greater thermal stress on the electric components as well as interior materials that might trigger reliability issues. In contrast, high-efficiency wireless speakers can be produced small and light.
Wireless speakers that have small efficiency require a larger power source in order to output the same amount of audio power as high-efficiency versions. Additionally, the thermal stress on the circuit board components as well as amp materials is more serious and may even decrease the reliability. While looking for a couple of wireless speakers, you'll find the efficiency in the data sheet. This value is usually shown as a percentage. Analog Class-D amplifiers offer a efficiency of around 25% whilst switching-mode amps provide up to 98%. The higher the efficiency value, the less the amount of energy wasted as heat. A 100-Watt amplifier with a 50% efficiency will have a power consumption of 200 W.
However, there are some things to note about efficiency. To start with, this figure depends on the amount of power that the amplifier is providing. Given that each amplifier is going to need a particular level of power, irrespective of the level of energy the amp provides to the speakers, the amplifier efficiency is larger the more power the amp provides and is generally specified for the greatest power the amplifier can handle.
The measurement setup of amp efficiency utilizes a power resistor that is attached to the amplifier. The amp itself is being fed a constant-envelope sine-wave tone. Next the power used by the resistor is tested and divided by the power the amp uses. Usually a full power report is plotted to show the dependency of the efficiency on the output power. This is why the output power is swept through several values. The efficiency at every value is measured plus a power efficiency graph generated.
Although switching (Class-D) amplifiers possess among the highest efficiency, they have a tendency to possess higher sound distortion than analog music amplifiers and reduced signal-to-noise ratio. Therefore you are going to have to weigh the dimensions of the cordless loudspeakers against the music fidelity. However, digital amps have come a long way and are providing improved music fidelity than in the past. Cordless loudspeakers which use Class-T amps come close to the audio fidelity of types which contain analog amps. Therefore picking a set of cordless speakers which use switching amp with good audio fidelity is now possible.
