The earphone disclosed by the invention has the beneficial effects that the earphone wearer can compare the pronunciation of the wearer in speaking the foreign language with the standard pronunciation so as to correct the pronunciation at any time; the environmental noise is effectively eliminated, and the earphone is suitable for being used for studying in various environments; interaction is increased, so that the earphone is deeply appreciated by children and pupils, and can improve the interest in foreign language learning; and the earphone is easy to adjust and convenient to use, and the receiving effect is good.
Description
Technical field
The present invention relates to a kind of earphone, the particularly a kind of earphone that can hear own sound.
Background technology
The importance of foreign language studying is self-evident, and it is to strengthen international exchange, the indispensable instrument of learning overseas advanced technology and theory.Now, the upsurge of whole people's foreign language learning is in the ascendant, no matter is the large, medium and small student in the school, and the civil servant who still is employed, office worker are in the foreign language studying of making a great effort.Just learning a foreign language the stage, most important to the pronunciation training of foreign language, the correctness of pronunciation will have a strong impact on reading and writing after the day for human beings that learns a foreign language, listen, say.The means that present foreign language pronunciation is trained have following three kinds substantially: 1, the student is being shone the pronunciation of books exercise phonetic symbol, is being read word and text, and the discovery mistake was corrected after teacher aside listened; 2, student oneself follows recorder, language repeater or CD player to read word and text repeatedly; 3, word and text are read in pronunciation in the voice classroom of special use.These traditional learning methods can both obtain certain effect, but all have many shortcomings: first method, and a student is to a teacher, and the classroom utilance is extremely low, and instruction cost is too big; Second method is that study must have a relatively independent quiet environment, when the noisy interference of environment, mistake will take place listen, and cause mispronouncing, and learner's pronunciation will influence peripheral people's study and work; The third method must have private classroom, and equipment price is expensive, is not that general school and unit can realize.In addition, these methodology foreign languages are all very uninteresting, are difficult to improve learner's, particularly pupil learning interest.Therefore long-term next, be engaged in foreign language teaching department and seeking Perfected process and the environment that a suitable people that just learns a foreign language learns to pronounce always.
Summary of the invention
The object of the invention provides a kind of earphone; Wearing the people both can hear and oneself read aloud the sound that foreign language is sent; Can hear that also audio frequency apparatuses such as external CD player, recorder or computer transmit the standard correct pronunciation, increase learning interaction property, greatly improve learning interest; Simultaneously can effectively suppress to eliminate the external environment noise again, people's pronunciation exercises is used for just learning a foreign language.
The earphone that can hear own sound provided by the invention is made up of headband, receiver, microphone, control box, it is characterized in that headband connects two receivers; Receiver perimeter mounted sound insulation circle; Be equipped with flexible pipe at a receiver shell, connect microphone, this receiver shell connects control box one end by headphone line; One circuit board (not drawing among the figure) and battery are arranged in the control box, and the control box other end connects two plugs by plug cord.
Circuit board in the control box provided by the invention mainly is made up of feedback amplifier, amplifier and amplifirer, and it has two signal input parts, and one from the electret transducer in the microphone, the wearing headphones people is read outer language convert signal of telecommunication input to; Another is from audio-source such as the external CD player of plug, recorder or computers, and the former amplifies through the one-level amplifier after feedback amplifier amplifies again, and importing amplifirer then carries out power amplification, and the last and latter is exported by loudspeaker in the lump.
Two adjusting knobs are arranged on the control box panel provided by the invention, and one is used to regulate and wears the people and read aloud the in a minute volume of sound; A volume that is used to regulate audio-source such as external CD player, recorder or computer.
The plug cord that the present invention connects control box is the twin-core shielding conductor, connects φ 3mm and φ 6mm plug respectively, being connected with the socket coupling of different size.
Sound insulation circle fixing on the receiver sheet of the present invention is oval ring-type, and size just can be surrounded people's ear, adopt outer cover leather, in fill out the porous foam Composite Preparation, can effectively isolate extraneous ambient noise.
Headband of the present invention two ends connect the U-shaped steel wire by the headband regulating block, through the shift position of regulating block on the U-shaped steel wire, regulate headband length, to be fit to different capitiform people wearing headphones.
The operation principle of earphone of the present invention is: electret transducer converts the sound that the wearing headphones people reads aloud foreign language to signal of telecommunication input negative feedback amplifier circuit, and this signal of telecommunication is imported the power amplifier amplification again through amplifying, and sends into loudspeaker at last; Connected by plug and directly to send into loudspeaker from the audio signal of audio-source such as CD player, computer, promptly the wearing headphones people signal of telecommunication that converts to of sounding is exported through loudspeaker with the audio signal in external audio frequency source simultaneously; Be fixed with shape and the ring-type sound insulation circle that people's ear overlaps basically on the headset earpiece sheet, be close to and wear people's ear, the sound of having isolated the earphone outside imports into wears people's ear, effectively reduces the external environment noise.
The invention has the beneficial effects as follows, 1, the wearing headphones people can be from the clear sound of hearing that the sound of oneself reading aloud foreign language and audio devices such as CD or computer send of earphone, be convenient to read and with RP relatively, differentiates the correct degree of oneself pronouncing; 2, increase interactive sense, liked by children and pupil, can improve foreign language studying interest; 3, wearing headphones people oneself reads aloud outer speech and the audio devices volume can be regulated respectively, regulates simply, and easy to use, audibility is good; 4, can effectively eliminate ambient noise, be applicable to various environment, comprise high-noise environment.
