Description
Technical field
The present invention relates to virtual reality, augmented reality, translator, directional loudspeaker, ultrasonic speaker and ear phone technologies
Field, and in particular to a kind of for virtually orienting earphone with the human-computer interaction acoustics of augmented reality.
Background technique
Earphone mainly divides open, semi open model, three kinds closed.
Closed earphone is exactly to wrap up user's ear by its included soft sound pad, is completely covered it.
For such earphone because there is big sound pad, head is also larger, but has sound pad that can use under the larger environment of noise
And it is unaffected.Earmuff is larger to prevent sound from entering and leaving to ear compressing, and sound is properly positioned clearly, more in professional monitoring field
See such, but this kind of earphone has one disadvantage in that be exactly that bass sound dye is serious.
Open earpiece is earphone pattern popular at present.The characteristics of such machine is by using spongiform micro-
Hole foamed plastic makes entrant sound ear pad.Its compact, wear it is very comfortable, do not use thick and heavy dye sound pad, then without
With extraneous isolation sense, otherwise sound can be revealed equally or hear extraneous sound.If the open degree of earphone is very
Height can hear the sound that another side unit issues, certain mutual feedback be formed, so that sense of hearing is natural.But it low frequency loss compared with
Greatly, also someone says that its low frequency is accurate.The general sense of hearing of open earphone naturally, wear relative comfort, but ear pad still with ear
Contact is common in the HIFI earphone of household appreciation.
Semi open model earphone is to combine the Novel earphones of closed and open two kinds of earphone advantages (it is one mixed-blood
Youngster, improves shortcoming at the advantages of having merged first two earphone), such earphone uses more diaphragm structures, in addition to a master
It moves except active vibrating diaphragm, there are also multiple passive driven vibrating diaphragms.It is plentiful simple and honest that there is low frequency to describe for it, the bright nature of high frequency description,
Many features such as clear layer, what is be nowadays widely applied on the earphone of many higher gears time is exactly this earphone.
Virtual reality is in use with augmented reality, there are also customer service, translator user, needs to wear ear for a long time
Machine, the above earphone since degree contacts ear differently, most people's meeting and do not feel like oneself, lead to work and study inefficiency,
These occasions, user mainly listen to voice, of less demanding to sound quality, and clear and natural can.
Therefore, a kind of super open earpiece for not contacting ear is needed at present, is worn for a long time for user.
Bugle is added before loudspeaker unit, is especially broadcasted the Professional sound box in loudspeaker, dancing hall in medium-high frequency and is added
Bugle.The low frequency of bugle speaker does not change, but the directive property of medium-high frequency enhances.Medium-high frequency speaker substantially vertically, water
Square to can control within 100 degree, can decay 12dB or more other than the angle.
The distance of traditional bugle system, centre and both sides that aditus laryngis to bugle exports differs.So sound transmission arrives
Time is also differed, and the phase angle differences of exit portion are very big, so the wave surface of exit portion is intended to centered on aditus laryngis
Spherical wave.Even if being spherical wave, the angle of flare of sound wave is also smaller than ventional loudspeakers more.
The middle section of splayed configuration bugle has been added to the plug of a diamond pattern.Diamond pattern plug among bugle can exist high pitch
The sound wave of bugle middle section does delay process, the time phase of the outlet each section of the sound wave made from the aditus laryngis of bugle to bugle
Deng.That is, sound wave is identical at the phase angle of outlet each section of the bugle.So in the wave of the exit portion of bugle
Front is intended to column type.
Ultrasonic speaker is the purpose that orientation Acoustic Wave Propagation is realized using the highly directive of ultrasonic wave.
For ultrasonic wave because frequency is higher, wavelength is shorter, it is not easy to diffraction occur, direction angle is smaller, possesses preferable direction
Property, and the frequency of audible sound is lower, wavelength is longer, diffraction is easy to happen, thus around the obstacle in communication process.
Different from the principle of conventional loudspeakers, ultrasonic speaker is using ultrasonic wave as carrier signal, then by audio signal
It is modulated in high-frequency signal and realizes aerial directional transmissions, and final realize in air demodulates certainly, can enable human ear
Enough hear the audio signal being reduced.
Sound wave direction propagation technology based on ultrasound, the basic principle is that audible signal is modulated to ultrasonic carrier
It on signal, and is emitted in air by ultrasonic transducer, the ultrasonic wave of different frequency is during air borne, due to sky
The nonlinear acoustics effect of gas, these signals can occur reciprocation and from demodulating, thus generate frequency for former supersonic frequency it
The new sound wave of the difference (difference frequency) of (and frequency) and frequency.As long as it is suitable that ultrasonic wave is chosen, difference frequency sound wave falls in audible sound section,
That is 20Hz-20000Hz.In this way, realizing the process of voice directional spreading by the high directivity of ultrasonic wave itself.
The 1960s, Westervelt and Berktay et al. had found ultrasonic wave nonlinear propagation in air
From demodulation effect, in the 1980s, Japan Kamkura T et al. has successfully made this speaker unit, thus experimentally
The correct of this principle is tested in fact, American Joseph in 2002 has then continued to press on the application of this technology in practice.
Currently, domestic have sound equipment enterprise to take the lead in having issued the directional loudspeaker array based on ultrasonic wave modulation, very well
Ground realizes the direction propagation of sound wave, can be used for indoor sound reinforcement system, auditorium sound reinforcement system, public address system and dedicated meeting
Conference system.
Therefore, a kind of super open orientation earphone for not contacting ear is needed at present, is worn for a long time for user.
