A Peek At The Cordless Functionality Of Bluetooth Speakers

By Linda Cullmann

It is easy to be puzzled by the terminology that cordless speaker suppliers employ to depict the performance of their models. I will explain the meaning of one usually used specification: "signal-to-noise ratio" to help you make an informed decision when buying a new a set of cordless speakers.

Once you have narrowed down your search by looking at some key criteria, like the level of output power, the dimensions of the speakers and the price, you are going to still have quite a few models to choose from. Now it is time to look at a couple of the technical specs in more detail. Every cordless speaker is going to create a certain amount of hiss and hum. The signal-to-noise ratio will help calculate the amount of noise created by the loudspeaker.

You can do a simple assessment of the cordless loudspeaker noise by short circuiting the transmitter input, setting the loudspeaker gain to maximum and listening to the speaker. The static that you hear is produced by the wireless speaker itself. Be certain that the volume of each couple of cordless loudspeakers is set to the same level. Otherwise you will not be able to objectively compare the amount of static between different models. The general rule is: the lower the level of noise that you hear the better the noise performance.

While taking a look at the cordless loudspeaker spec sheet, you want to look for a set of wireless loudspeaker with a high signal-to-noise ratio figure which indicates that the cordless loudspeakers output a small amount of noise. Noise is created due to a number of factors. One factor is that todays wireless loudspeakers all employ components such as transistors as well as resistors. Those elements are going to produce some amount of hiss. As the built-in power amp overall noise performance is mostly determined by the performance of components situated at the amp input, suppliers are going to attempt to choose low-noise components while designing the amplifier input stage of their wireless speakers.

A further cause of hiss is the cordless audio transmission itself. Usually types which utilize FM type broadcast at 900 MHz are going to have a rather high amount of static. Other wireless transmitters will interfer with FM type transmitters and bring about further hiss. For that reason the signal-to-noise ratio of FM style wireless speakers changes depending on the distance of the loudspeakers from the transmitter and the amount of interference. To steer clear of these problems, modern transmitters use digital music broadcast and usually transmit at 2.4 GHz or 5.8 GHz. This kind of audio broadcast offers higher signal-to-noise ratio than analog style transmitters. The amount of noise depends on the resolution of the analog-to-digital converters as well as the quality of other components.

Most of recent cordless loudspeakers use power amplifiers which are digital, also referred to as "class-d amplifiers". Class-D amplifiers utilize a switching stage that oscillates at a frequency in the range of 300 kHz to 1 MHz. This switching frequency is also noise that is part of the amplified signal. Yet, latest cordless speakerspecifications generally only consider the noise between 20 Hz and 20 kHz.

Makers measure the signal-to-noise ratio by setting the built-in amplifier such that the full output swing may be achieved and by inputting a test signal to the transmitter that is typically 60 dB underneath the full scale of the speaker amp. Subsequently, the noise floor between 20 Hz and 20 kHz is measured and the ratio to the full-scale signal calculated. The noise signal at other frequencies is eliminated through a bandpass filter throughout this measurement.

Time and again the signal-to-noise ratio is expressed in a more subjective manner as "dbA" or "A weighted". This technique was designed with the knowledge that human hearing perceives noise at different frequencies differently. Human hearing is most sensitive to signals around 1 kHz. However, signals under 50 Hz and above 13 kHz are hardly heard. The A-weighted signal-to-noise ratio is typically larger than the unweighted ratio and is published in most cordless loudspeaker parameter sheets.

Selecting A Pair Of Efficient Wireless Speakers

By Michelle Jaeger

Current wireless loudspeakers will by nature squander some amount of power they consume. Deciding on pair of cordless loudspeakers with high efficiency could minimize the amount of squandered energy. I will clarify a number of little-known facts about efficiency that will help you get the ideal type. The less efficient your cordless speakers are, the more power is going to be squandered which results in several difficulties: Cordless loudspeakers that have lower power efficiency will waste a great amount of energy. Its best to make note of the added power expense while choosing between a high- and low-efficiency type. The squandered power is dissipated by the cordless loudspeakers as heat. Cordless speakers with small efficiency routinely have various heat sinks to help dissipate the wasted power. Heat sinks as well as fans are heavy, use up room and also create noise. To help radiate heat, low-power-efficiency amplifiers need adequate air movement. Thus they cannot be put in places without any circulation. Additionally, they cant be fitted in water resistant enclosures.

A fairly large amount of power is radiated as heat if you get a set of low-efficiency wireless speakers. This can contribute to a number of problems: Cordless speakers that have low power efficiency are going to squander a great amount of power. Its best to make note of the additional power expense when choosing between a high- and low-efficiency product. The wasted energy is dissipated by the wireless loudspeakers as heat. To protect the circuit components, low-efficiency wireless loudspeakers must find solutions to get rid of the heat which is created. Usually extra elements have to be included to radiate adequate power and preserve the optimum running temperature. These components usually are heat sinks and also fans. These heat sinks consume a reasonable amount of space and make the cordless loudspeakers bulky and heavy. Additionally, they add to the cost of the cordless speakers. In order to help dissipate heat, low-power-efficiency amplifiers require adequate air circulation. Thus they cant be placed in areas with no circulation. Furthermore, they cant be installed in waterproof enclosures.

Since low-efficiency cordless loudspeakers will deliver merely a small percentage of the energy consumed by the amplifier as useful audio energy, the amplifier needs a bigger power supply than high-efficiency products resulting in more expensive. Additionally, because of the large amount of heat, there is going to be significantly greater thermal stress on the electric elements and internal materials that might trigger dependability complications. In comparison, high-efficiency wireless loudspeakers can be produced small and light. The efficiency is displayed as a percentage in the cordless loudspeakers data sheet. Class-A amplifiers are amongst the least efficient and offer a efficiency of approximately 25% only. In contrast, switching amplifiers, also referred to as "Class-D" amplifiers offer efficiencies of up to 98%. From the efficiency percentage it is possible to calculate the amount of power the amplifier will squander. An amp which has a 50% efficiency will waste 50 % of the used energy. An amplifier with 90% efficiency will squander 10%.

The power efficiency is shown as a percentage in the wireless loudspeakers data sheet. Various amplifier topologies deliver different power efficiencies. Class-A amps are amongst the least efficient and Class-D the most efficient. Standard power efficiencies vary from 25% to 98%. Getting an amp with an efficiency of 90% for example will mean that 10% of the power that is used is squandered when 90% would be audio power.

Yet, there are several things to note regarding power efficiency. For starters, this figure will depend on on the amount of power that the amplifier is providing. Amps have larger efficiency while providing higher output power than when working at small power mainly because of the fixed energy that they use up irrespective of the output power. The efficiency figure in the amp data sheet is normally provided for the highest amp output power. The measurement setup of amplifier power efficiency makes use of a power resistor that is connected to the amplifier. The amplifier is being fed a constant-envelope sine-wave tone. Next the power absorbed by the resistor is tested and divided by the energy the amp uses. To get a full power efficiency profile, the audio power of the amplifier is swept between several values. At every value the efficiency is measured and then plotted onto a graph.

Cordless speakers that use switching-mode amplifiers have a switching stage that causes a certain amount of non-linear behavior. Thus wireless speakers that use Class-D amplifiers commonly have smaller audio fidelity than products utilizing analog Class-A amps. Therefore you will need to base your decision on whether you need small dimensions and low energy usage or greatest audio fidelity. On the other hand, the most up-to-date cordless speakers that use switching-mode audio amps, such as Class-T amps, provide audio fidelity that comes close to that of low-efficiency analog amplifiers and can be manufactured ultra small and lightweight.
