Description

Semi-closed sound channel training device Technical Field The utility model relates to the technical field of vocal tract training devices, in particular to a semi-closed vocal tract training device. Background In voice training, the respiratory airflow exercise of the half-resistance channel is widely applied, can improve the stability and control force of airflow use of patients with hoarseness, can be used as a voice warming mode of an artistic singer, and has the scientificity of being commonly known in the voice training industry. At present, a common training mode is to fix a plastic straw between an upper lip and a lower lip by means of the plastic straw and breathe out air flow on the back of hand, so that the breathing condition can be known, the correct breathing is that the air flow is evenly breathed out, if the breathed air flow is uneven or the air flow heats, excessive force sounding behaviors are indicated, the straw is inconvenient to use in a straw training mode, the straw is difficult to put into a pocket and a handbag, and meanwhile, the straw is of a fixed length, the air flow resistance cannot be adjusted according to a user, and the straw is inconvenient to use in daily life. Disclosure of utility model The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing the semi-closed sound channel training device which is small in size, convenient to carry in daily life and adjustable in training resistance. The air channel block is connected with the air channel block in a sliding way and used for adjusting the size of air flow, an air cavity for the air flow to pass through is formed in the air channel block, a buccal part communicated with the air cavity is arranged at one end of the air channel block, a sliding groove communicated with the air cavity is arranged at the other end of the air channel block, a clamping block in sliding fit with the sliding groove is formed on the bottom surface of the sliding block, the bottom surface of the sliding block is tightly attached to the upper surface of the air channel block, and two guide blocks are arranged on the upper surface of the air cavity, and each guide block is in sliding fit with the sliding block. Further, the upper part of each guide block is provided with a plurality of scale points. Further, a push block for pushing a finger is arranged on the upper surface of the sliding block, a yielding groove is formed in the middle of the push block, and the yielding groove is correspondingly matched with the corresponding guide block in a guiding manner. Further, protruding blocks are arranged on two sides of the pushing block, and each protruding block is correspondingly in sliding fit with the lower surface of the corresponding guide block. Further, the cross section of the air cavity is arranged to be circular or elliptical. Further, the upper surface of the pushing block is provided with a marking hole corresponding to the clamping block. Further, the cross section of the air cavity is set to be rectangular. Further, one end of the air passage block, which is close to the sliding groove, is provided with a hanging lug. The sliding block has the beneficial effects that as the guide block is matched with the sliding block structure, the sliding block is in sliding extrusion with the guide block through the protruding block, the lower surface of the sliding block is tightly attached to the upper surface of the air passage block and is used for compacting the sliding groove, so that air flow is prevented from flowing out of a gap, a user can adjust the front and rear positions of the sliding block by pushing the pushing block, and the sealing degree of the sliding groove by the sliding block is determined by matching with the scale points and the marking points, so that the user can automatically adjust the air flow resistance degree, the optimal training resistance is achieved, the structure is compact, the use is convenient, the whole size is small, and the sliding block is convenient to carry in daily life.
