Karaoke microphone buzzing

Here are some reasons that may cause the karaoke microphone to produce a buzzing sound, let's explore with Electronics - Furniture Cho Lon right away.

During use, many people have the habit of holding the wireless microphone very close to the speaker's position, while also directing the microphone's body straight at the speaker. This causes the sound emitted from the speaker to be picked up by the microphone, which is then amplified by the speaker, resulting in the sound being greatly magnified. This cycle causes the karaoke microphone to buzz.

Due to users pointing the microphone directly at the speaker

Elements within a room such as wall design, room structure, arrangement of objects, etc., all have the ability to reflect sound when emitted from speakers. This creates a space with a lot of background noise and the sound resonance of these noises may affect the Bluetooth karaoke microphone.

Behind the diaphragm of the karaoke microphone, there are ventilation holes designed. If these holes are blocked, it will cause resonance inside the microphone body, which is also one of the reasons why the karaoke microphone produces a buzzing sound.

If the user inadvertently covers the antenna of the karaoke microphone with their hand, it will cause the sound to buzz. Therefore, when using it, we need to pay attention to holding it around the body of the microphone and not covering any other part of the device.

Simply put, a karaoke microphone experiencing power deficiency is a phenomenon where the audio signal exceeds the reserved Headroom, reaching the Clip level, causing the emitted sound quality to distort, resulting in a buzzing sound.

*Headroom is the reserved space for audio signal from normal level to maximum level. When it reaches the maximum level, it's called Clip.

Usually, the issue of karaoke microphone buzzing can also be due to the influence from other devices in the sound system, especially amplifiers and speakers. If the amplifier doesn't have enough power to operate at a stable output level, it will cause buzzing. Additionally, improper adjustments of sound elements by users (from the control knobs on the amplifier and speakers) can also lead to sound output issues such as buzzing.

Influence from adjusting sound on speakers

We've identified some common causes of buzzing on Bluetooth karaoke microphones. Now let's explore the corresponding solutions for each cause:

● If it's due to the microphone being too close to the speaker: Move farther away from the speaker, and avoid pointing the microphone directly at it to limit the microphone picking up sound from the speaker.

● If it's due to sound resonance phenomenon: Limit the placement of too many objects near or within the sound system setup.

● If the ventilation holes on the microphone are blocked: Properly clean the microphone to remove accumulated dust.

● If it's due to improper microphone handling: Hold the microphone in the middle section to minimize holding the tail of the microphone, as this is where the antenna is located.

● If it's due to the influence from amplifier and speakers: Adjust the settings of the sound elements on the amplifier and speakers to blend the emitted sound better and prevent buzzing.

A karaoke microphone is an indispensable device in a sound system to perfectly cater to the singing needs of music enthusiasts. However, if the karaoke microphone produces a buzzing sound, it will detract from our listening experience, rendering it imperfect.
