Bluetooth technology is everywhere these days, but few people understand how it works. Luckily, thanks to modern technology, you can find out How Bluetooth Speakers Work. These handy devices give you instant access to your music or podcasts, wherever you are in the room, and work even when you don’t have an internet connection. Join us to learn more about this technology.
What is Bluetooth?
To understand a wireless Bluetooth speaker, you need first to understand how phones work. Cell phones use radio waves to communicate with cell towers. These towers can be found as far away as two miles away.
Bluetooth technology uses much weaker radio waves. The Bluetooth range is limited to 10 meters. To ensure wireless Bluetooth speakers work, they should be located within a few feet of the source.
The most advanced devices, mainly for industrial use, will have a range of approximately 100 meters. However, consumer appliances will seldom offer the same content.
A Bluetooth speaker is a type of speaker that makes it easier to listen to music and watch movies. They are more convenient than traditional speakers because they don’t require wires or cables to connect to the audio source.
You can use the portable speaker remotely from your smartphone, tablet, or iPod without needing to connect to any audio jack ports. The external speaker can be carried around as a portable entertainment source.
How Do Bluetooth Speakers Work
Bluetooth speakers function just like wired speakers except that they receive radio signals.
Hard wired speaker cables are used to transmit speaker-level audio signals to wired a passive speaker. Wired active speakers can receive speaker-level alerts via speaker cable or line, microphone, and instrument level signals using a thinner audio cable.
A Bluetooth speaker receives their audio wirelessly via Bluetooth, as their names suggest.
To be more exact, the Bluetooth speaker’s built-in power amplifier will wirelessly receive the audio signals via Bluetooth.
Bluetooth protocols can carry standard line-level signals as they are. These signals level, like in wired setups, requires amplifiers to drive the loudspeaker driver properly.
Wireless speakers must be wirelessly connected to an audio device to function correctly. In the section How to Pair Bluetooth Speakers to Bluetooth Audio Devices, we’ll show you how to pair wireless speakers with different smart devices.
The speakers and digital audio devices form a Piconet when they are paired. This allows the device to send its audio signal via Bluetooth to the wireless speaker.
Wireless speakers with voice assistant technology or pause/play controls can also transmit information via Piconet to the audio device.
Before the Bluetooth receiver can receive the digital audio signal from the speaker, it must pass through two components.
First, Bluetooth transmits digital audio. Therefore, the received signal must first be converted to an analog audio signal. This is done using a built-in converter digital-to-analog.
The converted analog audio is then sent through a power amp, as we have discussed previously. The amplified signals will be low enough impedance to drive the speaker driver(s) correctly.
Once the signals have been passed through the driver, it is his job to create sound waves that correspond with the audio signal. This is how a Bluetooth speaker hears the audio signal.

Before we go into the details about how Bluetooth audio is transmitted, let’s look at how audio travels from the Bluetooth device to the Bluetooth speaker. Then, let us see how it is converted into sound waves that the listener can hear.
This is the signal flow from a Bluetooth audio player pairing Bluetooth speaker and the listener’s ears:
- The Bluetooth-capable audio device plays a digital audio signal.
- This codec encodes the audio signals (typically SBC, or Low Complexity Subband Codec) by A2DP’s transfer standard.
- This encoded audio signal acts as the modulating signal for the Bluetooth UHF radio carrier signal.
- Radio carrier waves are wirelessly transmitted as per Bluetooth standards between an audio device’s Bluetooth transmitter and a Bluetooth speaker’s BT receive.
- The Bluetooth receiver decodes then the modulation signal received from the carrier wave.
- The A2DP encoded signals can then be further decoded to the digital audio signal. Compression losses are applied when decoding or encoding the signal.
- The speaker’s digital-to-analog converter converts this digital audio signal into an analog format.
- An amplifier circuit is used to amplify the analog audio.
- The amplified audio signals will then be sent to the speaker drivers. (Note that surround codecs require the audio signals to be split at this point to drive their respective drivers).
- The drivers convert their analog audio signal(s) into sound waves.
- The listener hears the sound waves.
This is a very user-friendly signals flow. A Bluetooth speaker and wireless technology are user-friendly because engineers and inventors have taken care of all the technical details. We can then use wireless technology with no thought.
To understand Bluetooth speakers better, it is helpful to see how Bluetooth technology transmits audio. And now, you are know How do Bluetooth speakers work.
If you have just bought a new Bluetooth speaker then you should read the way how to test your speaker first:
Bluetooth speakers offer many benefits. One is that they don’t require any technical skills to set up or operate. Turn on the Bluetooth speaker. Once your audio system recognizes it, the speakers automatically sync, and music can be played.
These wireless speakers are generally smaller than other types of speakers, but they produce a clear and high-quality sound that makes them a perfect appliance for your home.
They are also compact and portable, making them very useful for those who want to be mobile while listening to their favorite music.
A lack of connecting wires means that there is very little clutter in your home or studio.
Bluetooth speakers can be used with many entertainment Bluetooth devices, including smartphones, tablets, and smartwatches.
The limited range of these speakers can benefit because it prevents large data transmissions over long distances. This could cause interference with other Bluetooth devices and networks.
Your phone should warn you about security risks when you use Wi-Fi outside your home.
This is because hackers and scammers can take advantage of you.
Bluetooth allows you to do the same.
Bluetooth technology can be great for convenience and affordability. However, security measures aren’t being taken seriously enough.
Hackers could intercept your Bluetooth signal and gain access to your phone via software. Hackers can see your phone’s contents by connecting to an unsecured connection.
You can protect yourself by taking precautions. It’s only a matter of time before your device is hacked in a world with more connected devices.
If you are the DJ at a party, you will be paired with the speaker. You are the DJ, so people at the party know that you’re the one who controls the music. This makes you a target.
Any party member can intercept your signal to blackmail you.
Pay attention to where your phone is connected devices. Bluetooth is a given, but it’s essential to be aware of your surroundings before making yourself vulnerable.
It is impossible to say the same for the other disadvantage.
You’ll notice a decrease in the quality of music if you have ever connected your phone with a wireless speaker and then gone to the bathroom.
- Distance is the reason.
- This is why new technology exists to address this problem.
- Bluetooth audio systems don’t come in all forms.
How To Connect Two Bluetooth Devices Together
It’s easy to synchronize Bluetooth devices together. Once you activate the Bluetooth devices within range, the connection will be established automatically.
Communication between them takes place over a piconet. This is a short-range network that can include multiple Bluetooth devices.
Two Bluetooth devices can be connected to a single piconet if they are within the same Piconet. One will be a discoverable device, while the other will serve as a control center.
This is how your Bluetooth keyboard or mouse will automatically be available when your laptop starts. You can also change their properties and settings.
Bluetooth is more than a communication technology. Bluetooth, like all wireless technologies, offers data transfer capabilities. Without this, Bluetooth speakers wouldn’t be capable of playing audio.
