Insert earphone as previously discussed, it is characterized in that: described insert earphone is stereo insert earphone, be to be installed in from two loud speakers of different circuit in two chambeies of same shell, two loud speakers pick out acoustic transmission channel 3A, a 3B separately, and the length of acoustic transmission channel 3A, 3B is 155mm to 600mm.
Insert earphone as previously discussed is characterized in that: above-mentioned insert earphone is the insert earphone of any form in formula in inserting, big cavate, external ear formula, hanging, separation preventing or the stereo MP3/4 formula.
An important feature of the present invention is the movement with insert earphone, be that Microspeaker separates setting with the earplug head, the acoustic transmission channel of above length is set between Microspeaker and the earplug head, so the present invention to the lengthening acoustic transmission channel be because square being inversely proportional to of magnetic field intensity and acoustic transmission channel length, for example length increases by 2 times, and magnetic field intensity reduces to original 1/4; Smooth thereby the noise of the waveform of frequency response is reduced widely.The length of noise slip and channel of acoustic wave is directly proportional, and the CL10 tester test of being produced by Taiwan proves.So the channel of acoustic wave that extended, also improved tonequality simultaneously.
The depletion of magnetic field intensity and electric field strength can be calculated by the following method:
According to online report, magnetic field intensity and electric field strength are inequality, and in the distance of antenna less than wavelength 1/10th, if comparatively speaking antenna is very little with distance, so the depletion of electric field strength and magnetic field intensity and distance square or cube be inverse relation.(referring to the Silicon Valley motive force net);
Therefore, must increase the length of acoustic transmission channel, magnetic field intensity is weakened rapidly to alap level, this principle or formula are approved by University Of Suzhou's physics and the professor of technical college, doctoral advisor professor Di Guoqing, moreover audio signal or sound that Microspeaker produces are sent to the earplug head in ear by acoustic transmission channel;
Another important feature of the present invention is that insert earphone is provided with sound chamber or sound cavity: this sound cavity is set at the sound wave inlet of earplug and the exit of sound, and promptly advancing sound wave mouth to sounding mouth at earplug has a sound cavity.This place must be provided with a sound cavity, because the sound wave that passes through in very little acoustic transmission channel has been subjected to compression, so sound wave is freely loosened, make waveform adjusted, improved the sound of LF-response on frequency response when sound wave is returned to original sending (frequency range) basis, sent out until ear.The outlet of this sound cavity is provided with an aperture or several aperture, and is littler much doubly than the gross area of common earplug outlet, makes the sound chamber constitute a little audio amplifier, improved tonequality, and this hole diameter φ is: 2mm one 4mm.The shape of sound cavity: shown in each accompanying drawing; The sound cavity volume is generally 600mm
3To 3000mm
3
Another important feature of the present invention is that the employed material of this sound wave transmission passage of manufacturing is nonconducting insulating material, so just can stop the radiation on the mobile phone not passed in people's the ear by sound wave transmission passage; Simultaneously, lead used in the present invention is a metal isolation scribes, can stop high-frequency signal to pass through from lead like this, thereby reduce radiation intensity.
The function of sound cavity:
Play the proportionality action of frequency of sound wave response behind the sound wave process sound chamber, improved the frequency response waveform widely, thereby improved tonequality widely, and removed noise.
The comparison of tone-off cavity is arranged:
1, feel from sense of hearing aspect:
The tone-off cavity: the sound sounds that noise is big, and tonequality is bad; The sound cavity is arranged: the sound sounds very soft interesting to listen to; Because of LF-response has improved.
2, because the earphone tone-off chamber or the tone-off cavity of prior art so the curve characteristic gain inequality is big, make noise cause tonequality bad greatly, and sound sound hard; The radiation proof insert earphone that is provided with sound chamber or sound cavity of the present invention, because of the curve gain inequality of frequency response curve characteristic is little, so noise is little, the sound of various frequencies can both sufficiently discharge, so gentle in voice pleasing to the ear.
A kind of insert earphone of the present invention has following beneficial effect compared with prior art:
1, insert earphone of the present invention is because the acoustic transmission channel that extended, for example the length of channel of acoustic wave is 155mm to 600mm, can make the radiation intensity that is radiated people's ear reach 2mG that mobile phone inventor professor Shi Min proposes or below the 2mG, for example can reach the following requirement of 1.8mG or 1.8mG, really avoid electromagnetic radiation to people's brain with to the infringement of human body;
And the insert earphone of existing technology is because the length of acoustic transmission channel is not enough, for example be defined as 90mm, do not reach radiation-resistant effect, test through the applicant, the channel of acoustic wave that 90mm is long, above-mentioned radiation intensity can only reach about 8mG, and we think preferable acoustic transmission channel length for example: 380mm, this radiation intensity can be reduced to 1.8mG or less than 1.8mG, the mobile phone inventor thinks that 2mG and the above radiation of 2mG just have damage to human body, from above test result as can be seen: acoustic transmission channel because insert earphone of the present invention has extended, make the radiation intensity reach the These parameters that mobile phone inventor professor Shi Min proposes, avoided electromagnetic radiation to people's brain with to the infringement of human body, and existing technology since the length of channel of acoustic wave fall short of, therefore, do not reach the effect that prevents radiation;
2, the present invention advances sound wave to sounding mouth at earplug sound chamber or sound cavity, a sound cavity must be arranged herein, because the sound wave that passes through in very little channel of acoustic wave has been subjected to compression, make waveform adjusted so need allow sound wave freely loosen, the sound that sound wave is returned to the original frequency response that sends (frequency range) and improved LF-response sends out delivers to ear, the concrete shape in sound chamber is shown in each figure, and its volume is from 600mm
3To 3000mm
3, best volume is 1000mm
3The insert earphone of prior art does not have the sound chamber, and, in the exit of sound cavity of the present invention an aperture is set also, make the sound chamber constitute a little audio amplifier, improved tonequality, (insert earphone of prior art is large-area, has the aperture of a lot of outlets, be similar to a horn, so do not have the effect in sound chamber).Above-mentioned hole diameter φ of the present invention is 2mm-4mm.Can prove with the above-mentioned data that the CLIO tester that produce in Taiwan is measured about this point; The present invention is owing to there is a real sound cavity, and sound wave can freely loosen, and makes waveform adjusted, sound wave is returned on the basis of the original band width that sends, and has improved LF-response, makes the people can hear original not only soft but also dulcet sound;
3 moreover, described acoustic transmission channel uses nonconducting insulating material, and the radiation of collecting can not passed in people's ear by acoustic transmission channel, described lead uses metal isolation scribes, can stop high-frequency signal to pass through from lead.
