Breathing training device for vocal practice

Abstract

The present invention discloses a breathing training device for vocal practice, comprising a protective box and a training device body fixed within the inner cavity of the protective box. An intake pipe is connected to the front of the training device body, and a connecting sleeve is threaded onto the outer surface of the intake pipe. The intake pipe connects to a blowing hose and a breathing mask. A flow sensor and a pressure sensor are integrated within the airflow path to enable real-time monitoring of instantaneous exhalation flow rate and pressure. This allows users to obtain quantitative feedback on their breathing strength, stability, and duration, enabling scientific, personalized respiratory training. The modular configuration allows for easy replacement and disinfection of the breathing mask and blowing hose. The invention improves training efficiency and safety, particularly for vocal performance, speech therapy, and respiratory rehabilitation applications.
