Abstract

The utility model relates to a head cover for training the speech, which belongs to speech teaching equipment. The utility model is characterized in that the head cover for training the speech is composed of a speech isolating cover and an air resistor which are matched. The speech isolating cover is a sound blocking cover which is made of transparent material and can be completely buckled and worn at a head and neck part, the lower wall of the speech isolating cover is provided with an inlet and an air exhausting hole, and the external appearance can form shapes of a square body, or a cylindrical body, or a spherical body, etc. The air resistor clamped at the front lower wall of the speech isolating cover is a device which can discharge the air into the speech isolating cover, and comprises structures of a direct-current electric exhaust fan, etc. The utility model can cause the sound production and the auditory organ to be isolated from the surrounding environment, and the mutual interference of the surrounding sound can be reduced, when the students carry out the speech training. The head cover for training the speech has the functions of concentrating the attention, strengthening the spoken language training, and increasing the memory.

Description

The voice training head-shield

The utility model relates to the phonetic teaching equipment, and concrete is a kind of voice training head-shield.

At the foreign language teaching field, owing to lack language environment, the breakthrough of voice is important steps that foreign language is crossed the threshold.Can be the most loud, the most clear, read aloud the most fast---i.e. " three " oral cavity muscular training method and read the key point that coaching method has become spoken and Listening Training repeatedly again.The appearance of computer Language repeater has solved voice and has read, led in reading aloud and followed the imitation problem of reading again, but the student loud give classroom and family etc. when re-reading around environment bring noise, ambient noise also influences concentrating of attention of student simultaneously, is difficult to create " imagination language environment " to student oneself.Do not find to carry easily " voice training chamber " device at present in the technology as yet.

The purpose of this utility model is to provide a kind of voice training head-shield, as the student in the classroom and wait some to be unfavorable for using in the loud re-reading environment in the family, it can help making full use of the scattered time and carry out voice training, reaches the purpose that improves learning efficiency.

The purpose of this utility model is achieved in that

Adopt a kind of voice training head-shield, mainly be equipped with air governor and form by the voice cage.It is characterized in that: described voice cage is one can detain the transparent sound barrier cover that is worn over incidence fully, and its lower wall has inlet, vent and buckling groove; Shapes such as the profile of described voice cage can the side's of being body, right cylinder or spheroid; Preceding lower wall clamping one air governor of described voice cage has exhaust duct, direct current drive exhaust fan, fresh air inlet, charging device and chargeable battery in this air governor shell; There are structures such as switch, circumscripted power line and pilot lamp on its surface.

The utility model has the following excessive effect that actively has:

The utility model has adopted the voice cage to be equipped with the design proposal of air governor, and it can isolate or cut down sound wave in cover and propagation and diffusion outside covering; Simultaneously because there is air governor in cover, to blow into fresh air, make discharges of being flowed of hot-air in the cover and stale air, air is fresh in can keeping covering can lower the temperature again, makes it to do the long period to train usefulness.The utility model can reduce the phase mutual interference of voice training head-shield internal and external environment sound, can enlarge the sensory effect of the sound of oneself again, reach the purpose of focusing one's attention on, strengthening the oral cavity muscular training and promote memory when helping student's Oral Training the hearing organ.The utlity model has simple and reasonable, portably use advantages such as convenient, be fit to all students and foreign language learner and use.
