The invention can eliminate the distortion of sound, and can obtain practical and accurate scoring results.

Description

technical field [0001] The invention relates to a singing scoring device, in particular to a vocal collector for singing and commenting. Background technique [0002] Singing scores have become a trend in many entertainment venues, especially karaoke. The singing scoring in the prior art is to download the singing scoring software on the terminal, and realize the scoring function on the acquired singing voice through the software. The terminal must support singing scoring software. Using the singing scoring software often only roughly estimates the overall score. It uses the singing decibel data as a displacement reference for scoring. Therefore, the scoring result mainly depends on the accurate collection of singing decibels. The collected sound is easily distorted. The result of singing scoring in the original equipment is often unsatisfactory, and its reason is that the collection to singing decibel is lacked, so the scoring result of above-mentioned singing scoring sof...
