Abstract
The utility model relates to an earphone for contrasting pronunciation. Therefore, the earphone helps learning language. A sound conduction system, comprising a hollow pick-up cavity, a sound conduction pipe and a hollow poly-sound cavity, can feed back voice of learners to learners themselves, and contrasts to sound sent out by loud-speakers.
Description
The utility model relates to a kind of earphone that is used for the sense of hearing.
Existing earphone is mainly by Microspeaker, and lead and plug are formed, and such earphone only plays the effect that helps the learner to practise hearing in learning a language, because the learner is being with earphone, just can hear the pronunciation of oneself.And in the process of learning a language, the learner consciously contrasts the pronunciation of oneself and the difference between professor person's pronunciation is very important, by the difference of contrast pronunciation, the mistake on the learner can correct one's pronunciation with comparalive ease.Especially for foreign language studying, this point very important that seem, but existing earphone does not possess this function.Specialty can not heard own sound by microphone with earphone, monitors the pronunciation of oneself, but the very complicated stereo set of needs, and cost an arm and a leg, can not utilize the common radio-cassette player of family expenses to practise.
The purpose of this utility model provides a kind of contrast earphone that utilizes common radio-cassette player study pronunciation.
The utility model can be finished by following mode: utilize electroacoustic principle and sound reflection conduction principle, and both are combined.From the signal of telecommunication of recorder output, by plug, lead and Microspeaker are transformed into sound, and Microspeaker communicates with poly-sound cavity, and sound directly imports poly-sound cavity into.Poly-simultaneously sound cavity and sound conduit join, sound conduit is connected with the pickup cavity again, the pickup cavity is a hollow, and have a cavity body of hole, by hole, the pickup cavity is collected learner's sound, and by sound conduit transfer voice is arrived poly-sound cavity, according to sonic propagation principle and experiment showed, that sound can transmit in the tubular bodies of hollow.Therefore, the earpiece holes that in poly-sound cavity or by poly-sound cavity, links to each other, the learner can hear that promptly the sound of oneself can hear the sound of radio-cassette player again.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is a contrast earphone fundamental diagram.
Fig. 2 is a kind of contrast earphone embodiment schematic diagram.
Fig. 3 is a kind of contrast earphone embodiment schematic diagram.
Press Fig. 1, the present invention is made up of electroacoustics system 13 and sound conducting system 14, and the direction of arrow is the transfer voice direction among the figure.The signal that recorder 11 sends passes to poly-sound cavity 4 by electroacoustics system 13, the sound conduction system feedback that the sound that the learner sends is formed by pickup cavity 8 and sound conduit 5 is to poly-sound cavity 4, can hear promptly that from poly-sound cavity 4 learners 12 sound of oneself can hear the sound of radio-cassette player again.
Press Fig. 2, plug 7 links to each other with recorder, and the signal of telecommunication is by lead 6, and Microspeaker 3 is transformed into sound, and Microspeaker 3 is contained in the shell 2, and communicates with poly-sound cavity 4.The sound that the learner sends is collected by pickup cavity 8, is transferred to poly-sound cavity 4 by sound conduit 5, and the sound that the learner can not hear oneself by the earpiece holes 1 that communicates with poly-sound cavity 4 can not heard the sound of radio-cassette player again.
Press Fig. 3, plug 7 links to each other with recorder, and the signal of telecommunication is by lead 6, and Microspeaker 3 is transformed into sound, and Microspeaker 3 is contained in the shell 2, and communicates with poly-sound cavity 4.The sound that the learner sends is collected by pickup cavity 8, is transferred to poly-sound cavity 4 by sound conduit 5, and sound that promptly can not hear oneself by poly-sound cavity learner can not heard the sound of radio-cassette player again.Wherein cavernous body 10 and clamp clip 9 are the servicing unit of general earphone, no longer describe in detail.
Attractive in appearance for product, sound conduit 5 and pickup cavity 8 can use various materials to make.Earpiece holes 1 and pickup cavity 8 can clad sponge, do not repeat them here.
Characteristics of the present utility model are that Principles of Acoustics are used for the electroacoustic earphone, thereby so that the present invention can help the self-taught learner to pass through family expenses radio cassette player exercise pronunciation, need not complicated stereo set.
Claims (2)
1, a kind of earphone, it is characterized in that except that the conventional components of earphone, also comprise by pickup cavity 8, the sound conduction system 14 that sound conduit 5 and poly-sound cavity 4 are formed, wherein pickup cavity 8 is communicated with sound conduit 5, sound conduit 5 is communicated with poly-sound cavity 4, and poly-sound cavity 4 is communicated with loud speaker 3 again.
2, earphone according to claim 1 is characterized in that pickup cavity 8 is for having the cavity body of hole.
