Description

Technical Field

[0001] This utility model relates to the field of audio technology, specifically to an audio system with lighting function. Background Technology

[0002] Audio equipment is a common entertainment device used in people's daily lives, playing an important role in their daily routines and becoming increasingly popular among music lovers. For example, some music lovers use audio equipment to listen to music, sing, exercise, or dance.

[0003] Existing audio systems mainly consist of a cabinet and speaker units. The speaker units are installed inside the cabinet, serving as the sound-producing component, while the cabinet supplements the speaker units by correcting the sound. The sound-producing principle of a speaker unit is the conversion of electrical energy into sound. When different amounts of electronic energy are transmitted to the coil, the coil generates energy that interacts with the magnetic field of the magnet. This interaction causes the diaphragm to vibrate. Because the electronic energy is constantly changing, the speaker coil moves forward or backward, thus causing the speaker diaphragm to move accordingly. These movements change the density of the air, thereby producing sound.

[0004] The existing speaker structure has the following shortcomings during use:

[0005] 1) Speakers typically have only one speaker unit, resulting in poor sound quality and reduced entertainment value. In outdoor venues or large spaces, the sound penetration is not strong enough, greatly diminishing the user's enjoyment.

[0006] 2) The speaker lacks a lighting function, making it inconvenient to use at night and affecting the user experience.

[0007] 3) The sound system lacks a place to store microphones, which need to be stored separately, making them easy to lose and inconvenient to manage. Utility Model Content
