How does a lavalier microphone work?

A lavalier microphone, also known as a lapel microphone or clip-on microphone, is a small wired microphone widely used in film production and broadcasting. Lavalier microphones are characterized by being small and unobtrusive, so they can be used for conversation recording. It can be adjusted to a position close to the lips and out of sight, ensuring clear audio in a variety of recording environments, whether it's for vlogging, video reporting, or recording interviews.

When using a lavalier microphone, you need to pay attention to two things: how to place the microphone and how to connect it to the recording device. Today Comtang lavalier microphone manufacturer will explain these two points in detail:

How to place a lavalier microphone

When placing a lavalier microphone, it is important to consider whether the microphone is close to the sound source (usually the subject's mouth) to ensure better sound quality. Most lavalier microphones have an omnidirectional head, which means they can pick up sound from all directions, making them very inclusive when recording. It is generally recommended to place the microphone a hand's width from your lips at chest level (around 20 centimeters) to ensure that the audio is picked up naturally and cleanly.

01. How to mount a lavalier microphone on a clamp

All lavalier microphones come with a clip that allows you to attach the microphone to your clothing. These clips can be confusing for first-time users, but the operation is actually very easy. Simply remove the windshield from the microphone, clamp the cord clip, insert the microphone into the loop, then release the clip to secure the microphone and slide the windshield back into its original position.

02. Lavalier microphone installation

If you wear a piece of clothing with hidden edges, such as the lapel of the jacket, collar shirt seams or the edge of the tie, this time the clip-on microphone is most convenient to wear fixed. Be sure to keep the microphone away from any other clothing that may cause friction that may be heard during the recording.

However, if you are wearing a garment without hidden edges, such as a tank top or t-shirt, this can be a bit tricky. You can attach the microphone to the neckline, but be aware that if the microphone is located directly under the neck, the sound may be colored and sound a little strange. To avoid this sound, wear a shirt with a looser neckline or place the microphone on either side of the neck just below the chin.

If you are wearing an undershirt, it is also a good idea to attach a lavalier microphone to the shoulder straps, or mount the microphone directly under the headband (if there is a headpiece). However, please note that it is important to make sure that the microphone is placed 20 to 30cm away from the mouth and that there is no friction with clothing so that you get a good audio.

03. How to hide a lavalier microphone

How to hide the microphone's cable to make your videos look cleaner and more professional? You can hide the microphone directly under your jacket or inside your shirt. Professional sound recordists use medical tape to secure the cable to the inside of the shirt, and Velcro is also a good option.

Connecting a Lavalier Microphone to a Recording Device

Once you have secured your lavalier microphone, the next step is to connect it to your recording device. When doing this, pay attention to the type of device the lavalier microphone is going to be plugged into and whether or not you need to use a wireless radio solution.

01. Computers and mobile devices

The receiver can be plugged into the device without any operation and paired immediately when the microphone is turned on. At the same time, the receiver has a charging port so you can charge the device while recording. Simply plug the lavalier microphone into the headphone jack of your device and select the input/output device in the audio settings or recording software to start recording.

02. Lapel Clip Design

Sturdy and durable clip that can be easily attached to your clothes or wherever you need it. Provides a stable hold for picking up sound on the camera.

03.Multi-scene application:

Whether for personal video production, professional filming, live presentations or educational training, the wireless lavalier microphone provides excellent audio support.
