Some smart glasses that have open audio module at present have the sound to spill over the problem big, that the privacy is poor, because the sound wave amplitude that speaker front and back radiated is the same, opposite phase, consequently have the problem that the sound wave of front and back is offset to the user can not hear bass or bass effect is poor (sound short circuit phenomenon), is difficult to satisfy user's demand. And when the audio module is configured, directional sound production is realized by applying a dipole principle, and the far-field noise elimination effect of the dipole is inversely related to the length of the dipole, namely the longer the length is, the worse the noise elimination effect is. Therefore, in order to achieve a good sound-deadening effect, the dipole is generally short in length, so that the acoustic short-circuit phenomenon is not effectively suppressed, and the dipole is far from the ear canal when worn, and is low in sound and low in pitch.

In order to solve the above problem, the audio module 100 according to some embodiments of the present invention utilizes the characteristics of sound wave propagation to perform the layout of the radiation ports in a targeted manner, so as to form a reasonable acoustic duct, which can effectively weaken or eliminate the acoustic short circuit. In particular, referring to fig. 10, the ear canal orifice is indicated by a dashed circle, and the audio device according to the above embodiment is provided, wherein the proximal radiation port 105 is configured to have a set distance d from the ear canal orifice, the distal radiation port 106 is configured to have a set sound wave propagation distance a from the ear canal orifice, and a/d ≧ 3; a front sound guiding channel is communicated between the proximal radiation opening 105 and the first cavity 103, and/or a rear sound guiding channel is communicated between the distal radiation opening 106 and the second cavity 104.

It can be understood that, according to the characteristics that the propagation distance of the sound wave is doubled and the amplitude is attenuated by half, the near-end radiation port 105 is configured to be closer to the ear canal opening, and the far-end radiation port 106 is configured to be farther from the ear canal opening, so that when the sound wave radiated by the far-end radiation port 106 propagates to the ear canal opening, the sound wave radiated by the near-end radiation port 105 is far smaller, thereby weakening the sound short circuit and avoiding the bass missing. Based on this principle, in order to reduce or eliminate the acoustic short circuit as much as possible, the proximal radiation ports 105 can be as close to the ear canal opening as possible without affecting comfort and practicability, and the distal radiation ports 106 can be as far away from the ear canal opening as possible, so as to increase the distance difference between the two radiation ports to the ear canal (such as increasing the value of a-d or a/d), and thus the acoustic short circuit can be reduced to the maximum. The distances between the proximal radiation opening 105 and the distal radiation opening 106 relative to the ear canal opening can be configured appropriately according to the actual application scenario. The proximal radiation opening 105 may be covered by a protective cover 126, which may be dust-tight.

Referring to FIGS. 9 and 10, in the audio assembly 100 of the embodiment of the present application, the proximal radiation opening 105 is configured to have a set distance d from the ear canal opening, the distal radiation opening 106 is configured to have a set sound wave propagation distance a from the ear canal opening, and a/d ≧ 3. Since the sound wave needs to bypass the obstacle, the sound wave propagation distance a refers to the minimum value of the actual propagation distance of the sound wave, and since the sound wave attenuates as the propagation distance increases, the distance increases by one time, and the amplitude of the sound wave attenuates by half (6 dB). Thus, by increasing the ratio of a/d, the sound waves radiated from the second radiation surface 302 of the loudspeaker 300 through the distal radiation port 106 can be transmitted to the ear canal opening substantially lower than the sound waves radiated from the proximal radiation port 105 by the first radiation surface 301 of the loudspeaker 300, so that the sound waves radiated from the first radiation surface 301 of the loudspeaker 300 are mainly received by the ear canal of the user. Thereby, even in case the distance from the proximal radiation opening 105 to the ear canal opening is small, it is ensured that the difference between the sound wave propagation distance from the distal radiation opening 106 to the ear canal opening and the distance from the proximal radiation opening 105 to the ear canal opening is sufficiently large, so that the acoustic short circuit is effectively reduced or eliminated.

When the audio component 100 of the above embodiment is applied to smart glasses, when the audio component is worn, the sound wave of the second radiation surface 302 is radiated through the far-end radiation port 106, and then the sound wave far smaller than the sound wave of the first radiation surface 301 is radiated through the near-end radiation port 105, so that the sound short circuit is weakened, the good bass effect is ensured, and the requirement of a user on sound tone quality is met. And, when the intelligent glasses that use this audio frequency subassembly 100 were wearing, audio frequency subassembly 100 was put on outer auricle, and first radiation mouth can be corresponding to duct mouth position, need not to pack the radiation mouth into the duct in, supports open wearing, can avoid wearing the uncomfortable sense that brings for a long time.

Referring to fig. 10, in some embodiments of the audio component 100, the ratio a/d between the set sound wave propagation distance a and the set distance d may be configured to be 3, 3.5, 4, 4.5, 5 or other ratios according to the sound wave propagation characteristics. In practical use, the set distance d and the set sound wave propagation distance a satisfy: a-d is more than or equal to 20mm, the size is suitable for the audio frequency component 100 of the conventional intelligent glasses, and the audio frequency component can be supported or worn at the ear part of a person to form portable open type intelligent glasses. Based on the light and portable use requirement, the preferable size of some intelligent glasses can be d less than or equal to 10mm, or a more than or equal to 30 mm.

When the smart glasses with the audio assembly 100 of the embodiment of the present application are used, for the bystander at a regular social distance, the sound wave propagation distance from the two radiation ports to the ear canal mouth of the bystander is far greater than a, and the sound wave propagation distance from the two radiation ports to the ear canal mouth of the bystander can be considered to be equivalent, for example, referring to fig. 3, for the bystander at a distance M, the ear of the bystander is far away from the proximal radiation port 105, the ear of the bystander is far away from the distal radiation port 106, b is considered to be approximately equal to c, for the bystander at a regular social distance, the sound wave propagation distance from the two radiation ports to the ear canal mouth of the bystander is far greater than a, and the sound wave propagation distance from the two radiation ports to the ear canal mouth of the bystander can be considered to be equivalent, so that the sound waves radiated by the two radiation ports have almost the same amplitude and opposite phase when propagating to the ear canal mouth of the bystander, the sound waves can be mutually offset, so that the sound waves heard at a conventional social distance are very weak, and the sound privacy is good. For best privacy, it is desirable to maintain the same acoustic properties of the two cavities or/and the sound-guiding channels so that the sound waves radiated by the two radiation ports can be perfectly matched.

The audio frequency subassembly 100 of this application embodiment can connect in the spectacle frame 400 of intelligent glasses or ordinary glasses to wear the use, can adopt the open of open auditory canal to wear, still can effectively weaken the sound short circuit simultaneously, can guarantee the bass quality, guarantee good bass effect when open is worn. And the noise elimination of the far end is realized, and the privacy requirement of the user is met. In addition, the open wearing mode of smart glasses can avoid sealing the auditory canal, has promoted security and the travelling comfort of wearing, is suitable for wearing for a long time, therefore has higher practicality.
