Description

Technical Field

[0001] This utility model relates to the field of full-range speaker technology, specifically a full-range speaker with an adjustment mechanism. Background Technology

[0002] A full-range speaker is a speaker made with only one full-range driver. Since there is only one driver, it is impossible for one driver to cover all frequency bands. Generally speaking, full-range means wide-range, which means that the frequency range is relatively wide. In the past, full-range speakers covered a frequency range of 200-10000Hz. In recent years, with the continuous advancement of acoustic technology, most full-range speakers can now reach a frequency range of 50-25000Hz, and some speakers can extend the low frequency down to 30Hz.

[0003] In KTVs and similar venues, speakers are typically installed on the ceiling of the booth. Adjusting the speaker's installation angle changes its orientation to achieve a better singing and listening experience. However, once the speaker is installed, its position is fixed, resulting in slight differences in the timbre of songs heard from different locations within the booth. This lack of flexibility and slightly diminished atmosphere makes us want to address this issue by proposing a full-range speaker with an adjustment mechanism. Utility Model Content
