Description

A kind of headband receiver

Technical field

This utility model relates to ear phone technology field, is specifically related to a kind of headband receiver being applied on convenient multimedia and communication electronic equipment.

Background technology

Earphone is to be placed in by loudspeaker monomer in different suitable otoacoustic mechanisms (such as earplug shell or earphone enclosure), the electric signal that it accepts media player or receptor sends, the loudspeaker monomer utilizing ear converts it into the sound wave that can hear, and by suitable otoacoustic mechanism, sound wave is sent to the equipment of the head auditory system of people.

Current all of earphone, be no matter In-Ear, ear-sticking, half is In-Ear or totally enclosed type earphone is all adopt loudspeaker directly to award sound facing to ear side or facing to auditory meatus, this has resulted in effect in head, in head, effect is exactly that the person that listens to earphone sound that earphone is sent thinks that sound source comes from head, and custom audition generation great contrast naturally. " the most significant deficiency of earphone is exactly that sound field is unnatural " has become as the common recognition of headset user at present. In reality, when broadcasting with audio amplifier, acoustical signal sends from audio amplifier, by air borne, arrives human ear. At this moment, " the audio amplifier sound " that human ear is heard with hear that in nature, various sound are the same, through auricle, external ear, auditory meatus, are transmitted to ear drum membrane, by the perception of cerebral nerve institute. In this process, the auricle of people, auditory meatus, to the refraction of sound wave, diffraction and diffraction, all sound can be caused certain impact. Acoustically, with HRTF, namely " head-related transfer function " describes this impact. Just because of the impact of HRTF, the big brain-capacity of people rule of thumb judges the azimuth-range that sound sends. Even if people blindfolds also can judge direction and the distance that sound sends, here it is the judgement made according to the HRTF experience affected by brain. When appreciating music by earphone, sound is entered ears by the driver element of earphone directly " filling ", that is the auricle of people otherwise just do not awarded sound, otherwise suffered sound is all the vertical next loudspeaker monomer as auricle both sides, oncoming sound before auricle is come from as such as nature, such Auricle effect does not have, and HRTF is absent from.In this case, the brain of people just cannot accurately judge the azimuth-range of sound. This be also a lot of people feel with earphone appreciate music time, the main cause that feeling of sound field is unnatural, the location of musical instrument is seemingly virtual.

Auricle effect is also referred to as monaural effect, refer to that single the ear of people reflects the sound wave of different azimuth due to each position of auricle and has the time difference of US (millisecond) level, azimuth information is all brought to audition, sound wave and the sound wave of various different elevations angle incidence that horizontal plane is incident reflect at the position that auricle is different, reflection sound wave superposition, the discrete spectrum formed is different, its sound bearing is judged with this, especially the high frequency sound wave of more than 4khz there will be homophase addition between the echo of auricle each position, anti-phase subtract each other, interference even occurs, play comb filtering effect, produce different discrete spectrum shapes, make auditory system these difference of energy perception, judge orientation. the loudspeaker monomer of earphone on the market almost seldom comes from oncoming incident acoustic wave before auricle relative to the position of auricle as natural at present, Auricle effect is caused to be hardly obtained performance, cause effect in the head making people irritated, disconnect with the serious scene of actual acoustic image.
