Abstract
The utility model discloses a dual-channel headphone for voice teaching, belonging to the field of an English teaching apparatus. The dual-channel headphone is characterized by comprising a microprocessor, an encoder, a memory, a data interface, a voice input unit, a voice output unit, a voice memory unit and a power supply connected via a circuit. The voice output unit adopts the dual-channel headphone and comprises a left channel and a right channel; the voice input unit is connected with the encoder; the memory, the voice memory unit and the data interface are respectively connected with the microprocessor; the encoder, the voice memory unit and the voice output unit are connected via data; and the memory is used for storing voice and digital information. Compared with the prior art, the utility model has the advantages that the dual-channel headphone can realize targeted and real-time correction of pronunciation and increase the interest of users in learning, is easy to carry and use, has a low manufacturing cost and can be promoted easily.
Description
[technical field]
The utility model relates to a kind of equipment of language teaching, particularly a kind of phonetic teaching dual-channel headphone that is used for English teaching.
[background technology]
Education is the key of human progress and development, and language education is the key of becoming a useful person.For a long time, people constantly develop on the language teaching series products, have also released many products and have helped people's study.Such as the tape phonetical repeater, the RP that teaching material is read aloud by language repeater by elder generation, people read aloud teaching material then, and language repeater is recording voice then, and by contrast standard pronunciation and exercise pronunciation, people can improve pronunciation level.Along with the IT technical development, the numeral voice learning machine has replaced traditional tape phonetical repeater, becomes the main flow instrument of present English study.But pronunciation-learning system in the market, though voice repetition is arranged, with function such as reading, the user can external microphone, will ownly get off with the voice record of reading, and plays a record then, by user oneself comparison, adjustment is pronounced.But can't reach the immediate interactive between learner and the learning machine like this, allow the learner lose interest easily, also can't realize the teaching that corrects one's pronunciation targetedly.
[summary of the invention]
Technical assignment of the present utility model is at above the deficiencies in the prior art, and a kind of phonetic teaching dual-channel headphone that is used for English teaching is provided.
The technical scheme in the invention for solving the technical problem is: a kind of phonetic teaching dual-channel headphone is characterized in that: comprise microprocessor, encoder, memory, data-interface, voice-input unit, voice-output unit, phonetic memory unit and power supply that circuit links to each other; Described voice-output unit is a dual-channel headphone, comprises L channel and R channel; Described voice-input unit is connected with encoder; Described memory, phonetic memory unit, data-interface are connected with microprocessor respectively; Encoder, phonetic memory unit, voice-output unit data connect; Described memory stores has speech digit information.
Above-mentioned phonetic memory unit is the voice digital signal memory chip, comprises flash memory, timer, comparator.
Above-mentioned memory be among ROM, PROM, EPROM or the EEPROM any one.
Above-mentioned data-interface be among USB interface, blue tooth interface or the infrared interface any one.
Compared with prior art, the utlity model has following characteristics:
1, can realize the language teaching that instantaneity corrects one's pronunciation targetedly, reach the interaction between learner and the study equipment, improve learner's learning interest easily.
2, adopt the pattern of circumaural earphone, easy to use, the person's that can not influence the adolescents with learning hearing is grown.
3, cheap, be convenient to promote.
[description of drawings]
Fig. 1 is a structural representation block diagram of the present utility model.
[embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, the utility model comprises microprocessor, encoder, memory, data-interface, voice-input unit, voice-output unit, phonetic memory unit and the power supply that circuit links to each other.Described voice-output unit is a dual-channel headphone, comprises L channel and R channel.Described voice-input unit is connected with encoder; Voice-input unit can for described phonetic teaching with microphone external on the dual-channel headphone.Described memory, phonetic memory unit, data-interface are connected with microprocessor respectively.Described memory be among ROM, PROM, EPROM or the EEPROM any one; Store speech digit information.Described phonetic memory unit is the voice digital signal memory chip, and model is ISD1806, comprises flash memory, timer, comparator, and encoder, phonetic memory unit, voice-output unit data connect.Described data communication interface be among USB interface, blue tooth interface or the infrared interface any one.
During use, the learner wears the utility model, then microphone is sent the pronunciation of word, and voice-input unit microphone input voice audio signals is to encoder, and encoder is converted to digital signal with voice audio signals.This digital signal is at first imported the voice digital signal memory chip into, module with this signal record in the flash memory of chip and carry out timing; Microprocessor reads corresponding standard pronunciation digital information from memory, transfer to voice digital signal memory chip comparator and carry out duration relatively and adjust and to equate with the recorded audio duration, digital information behind the word speed frequency modulation is converted to voice signal by the voice digital signal memory chip and exports by L channel, and the recorded audio signals of original record is exported by R channel.The learner, both can correct at the pronunciation of oneself with the same word speed standard pronunciation that the L channel loudspeaker are exported simultaneously by my pronunciation of R channel loudspeaker output relatively.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection range of the present utility model.
