Modern technology manufacturers have minimized the use of cables and connection cords. Microphones do work via Bluetooth technology. And this is not just about singing devices. To talk on your mobile, you don't have to take your phone out of your pocket. The microphones built into the headphones work in a similar way. Today, wireless microphones are also used in the professional field. For example, the device helps teachers deliver lectures in large classrooms. And the guides easily move around the city with a group of tourists, telling them about local attractions.

What it is?

The first wireless microphone models appeared in the 60s and 70s of the last century. However, the devices have been under finalization for a long time. But just a few years after their presentation, wireless designs began to enjoy immense popularity among pop performers. Due to the lack of wires, the singer easily moved around the stage, and the singers even started dancing with a dancer, not being afraid to get confused and fall … Today, it is extremely difficult for a person to imagine life with wires.

Wireless microphone with Bluetooth technology - a device for transmitting sound.

Some models allow you to increase the volume of your voice, while others make it possible to communicate with people. But from the difference in the main purpose, the constructive part of the microphones does not change.

As described, microphones do not require additional acoustics . They, as an independent device, transmit incoming sounds in real time. Each individual model is endowed with individual capabilities:

• volume control;
• frequency adjustment;
• the ability to switch playback tracks;
• improved voice quality.

How does it work?

The signal from the microphone is redirected to the amplifier using radio waves or infrared rays. However, radio waves manage to create a wide range, so that sound can easily pass through various obstacles. In simple terms, the person's voice enters the microphone's transmitter, which converts the words into radio waves . These waves are instantly directed to the speaker receiver and the sound is reproduced through the speakers. In the design of microphones, where the speaker is located in the lumbar part of the device, the principle of operation is similar.

Any wireless device will not be able to function properly without charging.

Battery models must be recharged from the mains. Microphones with AA batteries or coin-cell batteries can only be restored to work by replacing them.

How to choose?

Choosing a high-quality Bluetooth microphone is a tricky one. And before you go to the store to shop, you need to decide on the main purpose of this device … There are no universal microphones.

For performances in a conference room, the simplest model is suitable, for karaoke a device with average parameters will do, and streamers need high-frequency designs. They will differ in frequency, sensitivity and power.

The next step in choosing is the connection method . Wireless microphones interface with sound receivers in several ways. A proven option is a radio signal. With its help, sound reproduction occurs without delay, even if the speaker is at a great distance from the sound receiver. The second way is Bluetooth. State-of-the-art technology found in almost all devices. For perfect signal transmission, the microphone and sound receiver must be equipped with Bluetooth version 4, 1 or higher.

Another nuance worth paying attention to is design features . Some models are designed for desktop use, other microphones must be handled, and lavalier devices are preferred by journalists.

It is also important to pay attention to type of selected device . There are 2 types of them - dynamic and capacitor . Dynamic models have a small speaker that picks up sound waves and converts them into electrical signals. Only the performance indicator and the sensitivity of dynamic microphones leaves much to be desired.

Capacitor designs are more durable and reliable. The incoming sound is converted into an electrical signal by means of a capacitor.

Directionality is also an important selection parameter . Omnidirectional microphone models pick up sounds from all directions. Directional designs only take sound from a specific point.

The technical characteristics of each individual microphone model are expressed in numerical values. For example, if the device is selected for home use, it is advisable to consider designs with a frequency of 100-10000 Hz. The lower the sensitivity, the easier it picks up sounds . However, for professional work, the sensitivity of the microphone should be as high as possible so that there are no extraneous noise in the recording.

To obtain high-quality sound, the resistance parameters must be high.

Thanks to this knowledge, it will be possible to acquire the highest quality microphone corresponding to the operational purpose.

How to connect?

There is no big difference between connecting a microphone to a phone, computer, or karaoke. However, before pairing, you need to prepare the new device for work. Gently take out the device and connect it to the charger. Once the microphone is charged, you can turn it on.

To pair the device with a Windows 7 or 8 computer, you need to check if the PC or laptop supports the microphone. And after that, you should follow a simple instruction.

• First you need to activate Bluetooth.
• Right-click the volume icon next to the clock.
• In the window that appears, select the "Recorders" item.
• In the list that opens, select the name of the microphone and by two clicks of the button call the "Device Application" window. Set "Use as default" and click "Apply".

There are a few simple steps to activate Bluetooth on your microphone and pair with another device

• Press the microphone button to activate Bluetooth.
• On the second device, make a "Search" Bluetooth. In the list that appears, select the name of the device and click on it.
• Primary pairing occurs with a password. By factory standards, this is 0000.
• Then enable any audio file on the main device.
• If necessary, adjust the frequencies.

The karaoke microphone connection system is similar. It remains only to install the program with songs.

For telephones, wireless microphones are used, combined with an earpiece . They are worn on one ear, which is very convenient for motorists. Designs can be small, slightly enlarged. Some people advise purchasing mini-models, but it cannot be argued that miniature devices will work correctly. Similar systems are used in many professional fields.

Here is the procedure for connecting a 2-in-1 Bluetooth microphone to the phone

• First you need to turn on the headset.
• Then activate Bluetooth on your phone.
• In the Bluetooth menu, do a search for new devices.
• In the resulting list, select the name of the headset and pair. In this case, you do not need to enter a password.
• After successful pairing, the corresponding icon will appear at the top of the phone.

Unfortunately, there are times when it is not possible to pair with a mobile device the first time. The reasons for these failures can be a mismatch of Bluetooth signals, malfunctioning of one of the devices. To prevent this from happening, it is recommended to purchase the headset only at specialized points . Otherwise, you can buy a fake, and it will be impossible to return the device or replace it.
