Abstract
Disclosed is a damage-free earphone which comprises a casing, a directional loudspeaker arranged in the casing, a connecting device and a fixing device, wherein the connecting device is used for connecting the directional loudspeaker and audio equipment. As the directional loudspeaker is arranged, the distance between the earphone and the ears is increased when the damage-free earphone is used, the damage to the ears is greatly reduced, and eardrums can be protected; and as the directional loudspeaker is adopted, the damage-free earphone has good directivity, audible sound is generated only in a well-regulated range, others cannot be influenced, and the damage-free earphone has a broad prospect of development.
Description
Technical field
The utility model relates to a kind of earphone, particularly relates to a kind of nothing and hinders earphone.
Background technology
Earphone because of its outstanding Portability, the performance of high-quality sound and outstanding soundproof effect, and very popular, in the life, is worn the people that earphone listens to the music and is seen everywhere.
Yet, live in for a long time and easily cause auditory nerve impaired under the noisy environment, cause noise dysaudia.Present young man can have on earphone in the street in order not allow the noise of the street often bother, and then sound is transferred to very large.The long-time earphone of listening, acoustic pressure directly enters in the ear, and the concentrated area is delivered on the very thin eardrum, has not a particle of the leeway of buffering, the easy like this tip that stimulates auditory nerve, the impulsion of stimulation causes acous exaltation, the as easy as rolling off a log auditory fatigue that causes.Also can cause the harmful effect of some generals, slightly feel pain etc. such as tinnitus, slight Hearing, hard of hearing and ear, serious, even can cause deafness.Nonetheless, still there are many people still to use for a long time earphone.
The utility model content
Based on this, be necessary for the deficiencies in the prior art, provide a kind of earphone that increases to hinder earphone to the nothing of ear distance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of nothing is hindered earphone, comprise housing, be installed in directional loudspeaker, jockey and fixture in the housing, this jockey is used for connecting directional loudspeaker and audio frequency apparatus.
Among embodiment, described jockey can adopt wire transmission therein.
Among embodiment, described jockey also can utilize Bluetooth technology to realize wireless transmission therein.
Among embodiment, described fixture is installed on the earphone therein, and fixture is provided with retaining piece.
Among embodiment, described retaining piece is a clip therein.
In sum; the utility model is without hindering earphone by being equiped with directional loudspeaker; during use, increase the distance of earphone to ear, greatly reduced the injury to ear; the protection ear-drum; and the employing directional loudspeaker, directive property is strong, only produces heard sound in the good scope of regulation and control; do not affect other people, have vast potential for future development.
Description of drawings
Fig. 1 is the schematic diagram of the directional loudspeaker course of work.
Fig. 2 is shown in Figure 1, directional loudspeaker operation principle schematic diagram.
Embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is elaborated.
The utility model comprises housing, is installed in directional loudspeaker, jockey and fixture in the housing without hindering earphone, and this jockey is used for connecting directional loudspeaker and audio frequency apparatus, and audio frequency apparatus can be the electronic audio devices such as MP3, MP4.Jockey can adopt wire transmission, in addition, also can utilize Bluetooth technology to realize wireless transmission, makes without the structure of hindering earphone and becomes easier.
See also Fig. 1 and Fig. 2, described directional loudspeaker comprises frequency overlapped-resistable filter, modulus walk around parallel operation VC33 chip, digital to analog converter, smoothing filter, ultrasonic power amplifier and ultrasound transducer array, during work, first armed audio signal x (t) is carried out voltage amplification, signal amplitude is adjusted to several volts at zero point a few volt scopes extremely.Then be converted into digital signal x (n) through frequency overlapped-resistable filter and ADC, deliver to again the VC33 chip and process.VC33 carries out amplitude adjustment, precompensation to x (n), produces carrier signal, carries out amplitude modulation(PAM) again, exports a digital am signal y (n).This digital am signal send ultrasonic power amplifier and ultrasound transducer array behind DAC, smothing filtering.Directional loudspeaker then is modulated at armed audio signal on the high-frequency carrier signal x (t), then this modulation signal y (t) is launched by ultrasonic transducer.The ultrasonic signal of launching has very strong directive property.
Described fixture is installed on the earphone, and fixture is provided with retaining piece, in the present embodiment, described retaining piece is a clip, and it can be clamped on the clothes, during use, to be fixed on collar or shoulder place without the retaining piece of hindering earphone, adjust angle, sound is only imported in user's the ear.Owing to having increased the distance of earphone to ear, greatly reduced the injury to ear, the protection ear-drum, and adopt directional loudspeaker, directive property is strong, only produces heard sound in the good scope of regulation and control, does not affect other people.
In sum; the utility model is without hindering earphone by being equiped with directional loudspeaker; during use, increase the distance of earphone to ear, greatly reduced the injury to ear; the protection ear-drum; and the employing directional loudspeaker, directive property is strong, only produces heard sound in the good scope of regulation and control; do not affect other people, have vast potential for future development.
The above embodiment has only expressed a kind of execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
