wireless speaker
Wireless speakers are speakers that receive audio signals using radio
frequency (RF) waves instead of audio cables. The two most popular RF
frequencies that support streaming audio to wireless speakers include a
variation of WiFi, IEEE 802.11, while others rely on Bluetooth to transmit
audio data to the receiving speaker. 1
Overview
• A main speaker unit, which combines the speaker with an RF receiver,
and an RF transmitter unit make up a wireless speaker. The
transmitter can be connected to any audio output device, including
high-end audio equipment, televisions, laptops, MP3 players, and
others. An RCA connector is typically used to do this. You have the
option to relocate your wireless speakers without the use of cords
because the receiver is placed where the listener wishes to hear the
sound.
Bluetooth
• Bluetooth 4.0 or even Bluetooth 5 is typically used in more recent
versions, and wireless speakers typically have a 10 meter range. In
order to communicate with one another, Bluetooth devices do not
need to be in direct line of sight with one another.
• The NFC mechanism may help some speakers pair with the source
device more easily.
Wireless Hybrid Speakers
• Some wireless speakers now include VOIP telephony functionality as
early as 2015. 4 Other variants include an FM radio. Higher-end
models come with an LCD screen for simple radio station selection
and storage.
•
Most wireless speakers have a built-in microphone, allowing you to
use your phone in hands-free mode to take and make calls. The music
stops when a call comes in and starts playing again when the call
finishes.

• a suction cup-mounted shower speaker that is fixed to the shower
wall
• A Bluetooth speaker known as a "shower speaker" is one that is
intended to be used in wet areas like showers or bathrooms in
general. Wi-Fi-enabled shower speakers are also available, albeit they
are less common.
• A Bluetooth device must first pair with the speaker. Typically, it is a
tablet or a smartphone. The music that will be played through the
speaker will originate from this device.
Acoustic quality
• The simplest versions only provide an output power of 3W, which is
insufficient for the best sound quality. High-end devices can use up to
10W, while midrange models can use up to 5W.
• One speaker is the maximum number of speakers for entry-level
devices, whereas two speakers are available for stereo sound output
on more expensive versions. Some wireless speakers increase low-
frequency reproduction for richer sound by adding a passive radiator.
Terminology
• Individual drivers or an entire loudspeaker system, sometimes known
as a "speaker cabinet," made up of a baffle, one or more drivers, and
a crossover, are referred to as loudspeakers. Although the meanings
of "speaker" and "loudspeaker" are recognized, the loudspeaker is
referred to as speaker 3 or loudspeaker 4 horn in Mexico, Panama,
Colombia, and Ecuador. The same is true for El Salvador, Honduras,
Nicaragua, Peru, Chile, and Argentina. "Cornet" is the name given to it
in Venezuela.
Design of the system crossover filter
• Active crossover system with two amplifiers
• Only the frequency range appropriate for each loudspeaker should be
transmitted to it. The signal can either be filtered before amplification
(known as active filtering) or after amplification to achieve this (called
passive filtering). Although passive crossover filters do not require
power, they do have several drawbacks:
•
boosted speakers
• connections to an amplified loudspeaker with jack-accepting input on
a combo connector
• Depending on the type, loudspeakers with power amplifiers can
accept a digital signal that adheres to the standard for their intended
application or an analogue signal at line level.
Response frequency
• The output over a given frequency range with a constant input level
over the whole frequency range is referred to as the frequency
response. The margin of variation is occasionally stated as 2.5 dB. In
order for a piece of equipment to be termed high-quality, it must at
least cover the range of audio frequencies, or frequencies that people
can hear (20-20,000 Hz).
•
However, the speaker's frequency response is not linear. The ideal
loudspeaker would have an equal amount of power at all frequencies
and provide a uniform response, but such a speaker does not exist.
The frequency response is frequently mentioned in the technical
specifications:
The maximum power (the signal peak)
• The maximum power (the signal peak) that a loudspeaker can
withstand before degrading is time-limited. It relates to the highest
instantaneous power value that can be used for a very brief period of
time. The greatest voice coil travel without damaging the diaphragm,
which is another loudspeaker restriction, is strongly connected to this
figure (this problem is called loudspeaker undercounter). This power
is higher than the average maximum power.
