In the correlation technique, some have open audio module's intelligent glasses, avoided closed ear canal mouth to the inconvenience and the danger that isolated external environment brought, but can produce more sound and spill over, the privacy is poor, and after open, because the sound wave amplitude of speaker front and back radiation is the same, the opposite phase, consequently under the condition that does not have any barrier, the sound wave of front and back offsets, thereby the user can not hear bass or bass effect difference (sound short circuit phenomenon), is difficult to satisfy user's demand.

Still some open intelligent glasses, when configuration audio module, utilize dipole principle to realize directional sound production, the far field noise cancelling effect of dipole is with the length negative correlation of dipole, and the length is longer, and noise cancelling effect is worse. 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.

For solving the above-mentioned problem, the embodiment of the application provides a spectacle frame leg and have intelligent glasses of this spectacle frame leg, set up the speaker in spectacle frame leg inside, utilize the characteristic of sound wave propagation, the overall arrangement of radiation mouth is carried out to pertinence, form reasonable acoustics pipeline, can effectively weaken or eliminate the sound short circuit, be applied to in the intelligent glasses, can adopt open wearing of open duct, can also guarantee the bass quality simultaneously, and realize the noise elimination to the distal end, satisfy user's privacy demand, in addition, the open wearing mode of intelligent glasses can avoid sealing the duct, the travelling comfort of security and wearing has been promoted, be suitable for and wear for a long time, therefore higher practicality has.

Fig. 1 is a schematic structural view of a spectacle frame leg 10 according to an embodiment of the present invention, fig. 2 is an exploded schematic structural view of the spectacle frame leg 10 shown in fig. 1, fig. 3 is a schematic view of the spectacle frame leg 10 according to an embodiment of the present invention when worn, referring to fig. 1 to fig. 3, the present invention provides the spectacle frame leg 10 according to an embodiment of the first aspect, which includes a speaker 200 and a body, the speaker 200 is located inside the body and connected to the body, and the speaker 200 has a first radiation surface 210 and a second radiation surface 220 capable of radiating sound waves, and is respectively used for radiating sound waves towards different directions. One end of the body is provided with a connecting part 400 for connecting a frame of the glasses, thereby assembling to form the complete glasses for wearing. The connecting part 400 can be detachably connected to the glasses frame, so that the glasses frame leg 10 and the glasses frame can be independently replaced, and the replacement cost can be reduced.

A first cavity 121 is defined between the inner wall of the body and the first radiation surface 210 of the speaker 200, a second cavity 113 is defined between the inner wall of the body and the second radiation surface 220 of the speaker 200, the second cavity being spaced apart from the first cavity 121, the first cavity 121 is used for receiving sound waves radiated from the first radiation surface 210 by the speaker 200, and the second cavity 113 is used for receiving sound waves radiated from the second radiation surface 220 by the speaker 200. The body is further provided with a proximal radiation port 122 communicating with the first cavity 121, and a distal radiation port 114 communicating with the second cavity 113. The proximal radiation port 122 is used for radiating sound waves towards the ear canal opening of the human body, and the distal radiation port 114 is used for radiating sound waves generated by the second radiation surface 220 at a position far away from the ear canal opening of the human body, so as to reduce or eliminate the phenomenon of acoustic short circuit at the ear canal opening.

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 122 is configured to be closer to the ear canal mouth, and the far-end radiation port 114 is configured to be farther from the ear canal mouth, so that when the sound wave radiated by the far-end radiation port 114 propagates to the ear canal mouth, the sound wave radiated by the far-end radiation port 122 is far smaller than the sound wave radiated by the near-end radiation port 122, 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 122 can be as close to the ear canal opening as possible without affecting comfort and practicability, while the distal radiation ports 114 can be as far away from the ear canal opening as possible, so that the distance difference between the two radiation ports to the ear canal is increased (e.g., the value of a-d or a/d is increased), and the acoustic short circuit can be reduced to the maximum. The distances between the proximal radiation opening 122 and the distal radiation opening 114 with respect to the ear canal opening can be configured appropriately according to the actual application scenario. The proximal radiation opening 122 may be covered with a protective cover 126 for dust protection.

Referring to fig. 1 to 3, in the temple 10 of the embodiment of the present application, the proximal radiation opening 122 is configured to have a set distance d from the ear canal opening, the distal radiation opening 114 is configured to have a set sound wave propagation distance a from the ear canal opening, and a/d ≧ 3, wherein, referring to fig. 2 and 3, it should be noted that the set distance d mentioned above may be the minimum distance between the edge of the proximal radiation opening 122 and the edge of the ear canal opening, and fig. 3 shows that d is very small because the proximal radiation opening 122 is located at the ear canal opening, so it is difficult to show d in fig. 3, so fig. 3 is performed with a lead wire. Since the sound wave needs to bypass the obstacle, the sound wave propagation distance a here 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). Therefore, by increasing the a/d ratio, the sound waves radiated from the second radiation surface 220 of the speaker 200 through the distal radiation port 114 can be transmitted to the ear canal opening substantially lower than the sound waves radiated from the proximal radiation port 122 by the first radiation surface 210 of the speaker 200, so that the sound waves radiated from the first radiation surface 210 of the speaker 200 are mainly received by the ear canal of the user. Thus, even if the distance from the proximal radiation opening 122 to the ear canal opening is small, the difference between the sound wave propagation distance from the distal radiation opening 114 to the ear canal opening and the distance from the proximal radiation opening 122 to the ear canal opening can be ensured to be large enough, thereby effectively reducing or eliminating the acoustic short circuit.

When the glasses frame leg 10 of the above embodiment is applied to the smart glasses, when the glasses frame leg is worn, the sound wave of the second radiation surface 220 is radiated through the far-end radiation port 114 and then is transmitted to the ear canal opening, and the sound wave is far smaller than the sound wave of the first radiation surface 210 and then is radiated through the near-end radiation port 122, so that the acoustic short circuit is weakened, the good bass effect is ensured, and the requirement of a user on the sound tone quality is met. And, when the intelligent glasses of using this spectacle frame leg 10 were wearing, spectacle frame leg 10 was erect on outer auricle, and first radiation mouth can be corresponding to duct mouth position, need not to fill in the duct with the radiation mouth in, supported open wearing, can avoid wearing the uncomfortable sense that brings for a long time.

In the temple 10 of the above embodiment, since the proximal radiation opening 122 is used for radiating sound waves towards the ear canal opening, when the temple 10 is worn, the proximal radiation opening 122 needs to be as close as possible to the ear canal opening, and the distal radiation opening 114 needs to be far away from the ear canal opening, so that the corresponding sound guiding channels can be set according to the relative distances among the proximal radiation opening 122, the speaker 200 and the distal radiation opening 114, for example:

a front sound guide channel 123 may be communicated between the proximal radiation port 122 and the first cavity 121, and a rear sound guide channel 116 may be communicated between the distal radiation port 114 and the second cavity 113, so that the speaker 200 may avoid the ear canal opening, sound waves radiated to the first cavity 121 by the first radiation surface 210 of the speaker 200 are conducted to the proximal radiation port 122 through the front sound guide channel 123 to radiate sound waves outwards, and sound waves radiated to the second cavity 113 by the second radiation surface 220 of the speaker 200 are conducted to the proximal radiation port 122 through the rear sound guide channel 116 to radiate sound waves outwards, so that the distance between the distal radiation port 114 and the ear canal opening can be increased, that is, the value of a/d is increased, thereby effectively reducing or eliminating acoustic short circuits and optimizing bass effects.

Or, only the front sound guiding channel 123 is communicated between the proximal radiation port 122 and the first cavity 121, and the rear sound guiding channel 116 may not be provided between the distal radiation port 114 and the second cavity 113, so as to simplify the internal structure, at this time, the speaker 200 may avoid the ear canal opening, and the distal radiation port 114 may be provided on the housing 100 at a position corresponding to the second cavity 113, so that when the distance between the speaker 200 and the proximal radiation port 122 is sufficiently large, the sound wave propagation distance a between the distal radiation port 114 and the ear canal opening and the distance d between the proximal radiation port 122 and the ear canal opening can satisfy a/d ≧ 3, that is, the acoustic short circuit can be effectively reduced or eliminated; in this embodiment, since there is no rear sound guiding channel 116, the sound wave radiated from the distal radiation port 114 by the second radiation surface 220 of the speaker 200 is larger than the sound wave radiated from the proximal radiation port 122 by the first radiation surface 210 through the front sound guiding channel 123, so that the cancellation effect is weakened, in order to improve the privacy of sound, a damping member may be disposed at the distal radiation port 114, and the aperture area and radiation damping of the distal radiation port 114 may be adjusted as required, so as to realize the radiation characteristic similar to that of the proximal radiation port 122, thereby improving the sound attenuation effect.

Or, only the rear sound guiding channel 116 is communicated between the distal radiation port 114 and the second cavity 113, and the front sound guiding channel 123 may not be provided between the proximal radiation port 122 and the first cavity 121, so as to simplify the internal structure, at this time, the speaker 200 may be disposed such that the speaker 200 corresponds to the ear canal when worn, and the proximal radiation port 122 may be disposed on the housing 100 at a position corresponding to the first cavity 121, so that when the distance between the speaker 200 and the distal radiation port 114 is sufficiently large, the sound wave propagation distance a between the distal radiation port 114 and the ear canal and the distance d between the proximal radiation port 122 and the ear canal can satisfy a/d ≧ 3, and thus the acoustic short circuit can be effectively reduced or eliminated.

When the smart glasses with the glasses frame legs 10 of the embodiment of the present application are used, for a person at a regular social distance, the sound wave propagation distance from the two radiation ports to the ear canal mouth of the person is far greater than a, and the sound wave propagation distance from the two radiation ports to the ear canal mouth of the person can be considered as equivalent, for example, referring to fig. 3, for a person at a far M point, the ear distance from the near radiation port 122 is b, and the distance from the far radiation port 114 is c, and since b and c are far greater than a, b can be considered as approximately equal to c, the amplitudes of the sound waves radiated by the two catheters are almost the same and opposite in phase, and the sound waves can cancel each other, so that the sound waves heard at the regular social distance are 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.

Referring to fig. 1-3, in some embodiments of the temple 10, the ratio a/d between the set acoustic propagation distance a and the set distance d may be configured to be 3, 3.5, 4, 4.5, 5, or other ratios, based on the acoustic propagation characteristics described above.

Referring to fig. 1-3, in some embodiments of the temple 10, the set distance d and the set acoustic travel distance a described above satisfy: a-d is more than or equal to 20mm, the size is suitable for the glasses frame leg 10 of the conventional intelligent glasses, and the glasses frame leg can be supported or worn on 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.

Referring to fig. 1 to 3, when the glasses frame leg 10 is worn or supported on the ear of a human body, the near-end radiation port 122 is located at a position close to the ear canal opening, for example, the distance d between the near-end radiation port 122 and the ear canal opening may be less than or equal to 20mm, and the sound wave propagation distance a between the corresponding far-end radiation port 114 and the ear canal opening may be greater than or equal to 60mm, so that a-d is greater than or equal to 20mm, and a/d is greater than or equal to 3, which can satisfy the miniaturized appearance, and can realize the above-mentioned good bass reproduction effect and good privacy, the ear canal is open when worn, which can reduce the risk, and does not need a specific clamping force, improve the comfort, and can satisfy the use requirement of long-term wearing.

The speaker 200 may be disposed in the accommodating cavity 112 in a vertical or horizontal manner, for example, the first radiation surface 210 and the second radiation surface 220 of the speaker 200 are parallel to the cross section of the accommodating cavity 112 (vertical), or the first radiation surface 210 and the second radiation surface 220 of the speaker 200 are perpendicular to the cross section of the accommodating cavity 112 (horizontal), and in specific implementation, the speaker 200 may be configured reasonably according to factors such as the overall structure or the internal layout of the housing 100. The present embodiment employs the speaker 200 of a horizontal type, and thus, the housing 100 has a thinner overall structure, thereby being more convenient to wear.

Referring to fig. 2, 4 and 5, in some embodiments, the housing 100 includes a mounting portion 110 and an extending portion 120, the mounting wall 111 is disposed in the mounting portion 110, a partition wall 115 is further disposed in the mounting portion 110, the partition wall 115 is connected to an inner wall of the mounting portion 110 and extends from the mounting wall 111 to a direction of the connecting portion 400, the partition wall 115 and a part of the inner wall of the mounting portion 110 surround to define a second sound guiding channel, and the distal radiation port 114 is disposed at a position on the mounting portion 110 corresponding to the second sound guiding channel and may be disposed at a top position so as to depart from a direction of an ear canal opening; the extension part 120 extends downward from one side of the mounting part 110, and thus, when the ear mount 300 is mounted on the auricle, the extension part 120 can extend to the mouth of the ear canal, the front sound channel 123 is located in the extension part 120, and the proximal radiation port 122 is disposed inside the extension part 120, so that the sound waves can be radiated corresponding to the mouth of the ear canal, and the sound waves can be transmitted to the human ear more intensively.

Fig. 6 is a schematic diagram of an outer side surface of the glasses frame leg 10 according to an embodiment of the present invention, referring to fig. 2, fig. 5 and fig. 6, in some embodiments, a first opening 124 communicating the first cavity 121 and the front sound guiding channel 123 is formed on an outer side of the extension portion 120, a structural member or a connecting member inside the extension portion 120 can be assembled or maintained through the first opening 124, the first opening 124 is covered with a surface cover 125, the surface cover 125 is detachably connected to the casing 100, so as to close the first opening 124, and the front sound guiding channel 123 is defined by the surface cover 125 and an inner wall of the extension portion 120. In some embodiments, the mounting portion 110 further includes an inner cover 117, the inner cover 117 is connected to the mounting wall 111 and the partition wall 115 on a side corresponding to the second radiation surface 220, the second cavity 113 is defined between the second radiation surface 220, the mounting wall 111 and the inner cover 117, and a second sound guide channel is defined between the partition wall 115 and the inner cover 117 and a side inner wall of the extension portion 120, so that the first cavity 121, the second cavity 113, the front sound guide channel 123 and the rear sound guide channel 116 are integrated into the casing 100, thereby making the structure more compact, facilitating a miniaturized design, facilitating wearing and improving wearing comfort.

The shapes of the front sound guiding channel 123 and the second sound guiding channel of the above embodiments may be any shapes, the sectional area may be adjusted according to the design requirement, and the sectional area S1 of the sound guiding channel is generally not larger than 1/2 of the effective radiation area of the loudspeaker 200. In some preferred embodiments, the sectional area S1 of the sound guide channel and the diaphragm area S2 of the speaker 200 satisfy: 1/2S2 is not less than S1 is not less than 1/8S 2.

As described above, since the sound wave propagation distance between the person at the M point far away and the two radiation ports is far greater than a, the amplitudes of the sound waves radiated by the two catheters are almost the same and the phases are opposite when the sound waves propagate to the M point, and the sound waves are cancelled out, so that the sound attenuation effect of the far end is realized, and the privacy is better and the surrounding environment is prevented from being disturbed by the sound. In some other embodiments, the cross-sectional areas of the leading sound channel 123 and the trailing sound channel 116 do not deviate from each other by more than ± 20% and the lengths do not deviate from each other by more than ± 20% for optimal sound attenuation.
