Description

Technical Field

[0001] The utility model relates to the technical field of music teaching appliances, and particularly relates to a sound training device. Background Art

[0002] Pronunciation training in music learning is a key link to improve singing level. In terms of breath application, learners are taught how to inhale deeply and exhale steadily to support sustained and stable vocalization. For example, abdominal breathing training can make the breath more sufficient. For the training of vocal cords, it is to adjust their vibration frequency and mode to achieve changes in different pitches and timbres. There is also resonance practice, guiding learners to explore head cavity, oral cavity, and thoracic cavity resonance to shape a rich and full voice;

[0003] When using instrument equipment to assist learners in practice, such as the Chinese utility model patent disclosed in the publication number CN211454923U: A singing voice pronunciation trainer. In this application, the display screen is slidably connected to the connecting rod through a fixing frame. When in use, the user places the box body on the desktop and opens the box cover to expose the display screen. The motor works to drive the output shaft fixed to its output end to rotate, so that the connecting rod fixed to its outer wall rotates. The user can adjust the inclination angle of the display screen according to their own height and habits, so that the user can clearly view the correction prompts on the display screen when practicing singing. However, the way it is placed on the desktop limits the user's activity range and cannot meet the needs of learners to move freely during pronunciation training. If a handheld device is used for pronunciation assistance practice, one or both hands need to operate the device, and the hands cannot be liberated, making it difficult for learners to assist pronunciation through body movements, thereby affecting the training effect.
