Technical Field

The invention relates to the technical field of wearable equipment, in particular to intelligent head-mounted equipment.

Background

The smart glasses generally refer to glasses that can perform functions of adding schedules, map navigation, interacting with friends, taking photos, playing audio, playing video, and making audio and video calls through voice or motion control, and can realize wireless network access through a mobile communication network.

Existing smart glasses are typically provided with only one speaker, e.g., an open speaker. The speaker radiates sound towards the ear of the wearer.

However, such a speaker has a relatively serious sound leakage. The sound emitted from the speaker is easily heard by surrounding persons. This results in poor privacy of the smart glasses.

Therefore, a new technical solution is needed to solve the above technical problems.

Disclosure of Invention

An object of the present invention is to provide a new technical solution of an intelligent head-mounted device.

According to a first aspect of the invention, an intelligent head-mounted device is provided. This intelligence head-mounted apparatus include the lens and with the shank that the lens formed the connection is same be provided with sound generating unit on the shank, sound generating unit includes first sound generating mechanism and second sound generating mechanism, first sound generating mechanism with second sound generating mechanism outwards radiates the sound wave through respective phonate hole, at the during operation, first sound generating mechanism and second sound generating mechanism's opposite phase, first sound generating mechanism is different with the distance of second sound generating mechanism to the same earhole of wearer.

Optionally, a cavity is arranged in the leg, the sound generating unit is arranged in the cavity, and a first sound outlet communicated with the vibration part of the first sound generating device and a second sound outlet communicated with the vibration part of the second sound generating device are arranged on the leg.

Optionally, the leg portion includes a connecting portion and a bending portion connected to one end of the connecting portion, the other end of the connecting portion is hinged to the lens, the cavity is disposed in the connecting portion, an inclined surface facing the ear hole is formed at one end of the connecting portion connected to the bending portion, the first sound outlet is formed in the inclined surface, and the second sound outlet is located on a side surface or a top surface of the connecting portion.

Optionally, the first and second sound emitting devices are responsive to the same electrical signal, the polarity of the first and second sound emitting devices being opposite.

Optionally, when installed, the polarity of the first and second sound generators is the same, and the polarity of the electrical signals of the first and second sound generators is opposite.

Optionally, the first sound generating device and the second sound generating device are the same in model.

Optionally, a distance between the sound outlet hole of the first sound emitting device and the sound outlet hole of the second sound emitting device is less than or equal to 30 mm.

Optionally, the sound outlet of the first sound-emitting device faces the ear hole of the wearer, and the distance from the sound outlet of the second sound-emitting device to the ear hole is greater than the distance from the sound outlet of the first sound-emitting device to the ear hole.

Optionally, a difference between a distance from the second sound emitting device to the ear canal and a distance from the first sound emitting device to the ear canal is greater than or equal to 5 mm.

Optionally, the sound outlet of the first sound emitting device, the sound outlet of the second sound emitting device and the ear hole are located on the same straight line.

According to one embodiment of the present disclosure, since the two sound emitting devices are opposite in phase and far less than the distance between the two sound emitting devices and the surrounding person, the two sound emitting devices form an acoustic dipole effect with respect to the surrounding person, so that the sound waves of the two sound emitting devices can at least partially cancel each other when being transmitted to the ears of the surrounding person, thereby significantly reducing the sound leakage phenomenon of the sound emitting unit.

In addition, because the two sound generating devices are at different distances from the same ear hole of the wearer, for example, the distance difference between the two sound generating devices is greater than or equal to 1cm, the two sound generating devices do not form an acoustic dipole effect relative to the wearer, and therefore the attenuation of the sound wave near the ear hole is small, so that the wearer can hear the sound generated by the sound generating unit. The arrangement mode of the sound production unit improves the listening privacy of a wearer.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

According to one embodiment of the present disclosure, an intelligent headset is provided. The intelligent head-mounted equipment is intelligent glasses and the like. As shown in fig. 1, the smart glasses include a lens 11 and a leg part forming a connection with the lens 11. For example, the legs are connected directly to the edge of the lens 11; alternatively, the lens 11 is fixed in the frame 12, and the leg is connected to the frame 12. Smart glasses typically include two legs. Of course, one leg may be provided according to actual needs.

The same leg is provided with a sound production unit. For example, one sound emitting unit is provided on each of the two legs. The sound emitting unit is used for radiating sound to a wearer. For example, components such as a power module, a wireless communication module, a processor and the like are arranged in the smart glasses, and the components are connected through the PCB. For example, the wireless communication module includes a bluetooth device, an infrared device, and the like, and is configured to receive an external wireless signal and transmit the wireless signal to the outside. The processor is used for processing the received wireless signals, converting the wireless signals into electric signals and transmitting the electric signals to the sound production unit through the PCB. The sound production unit converts the electric signal into an audio signal.

The sound emitting unit includes a first sound emitting device 14 and a second sound emitting device 15. The first sound emitting device 14 and the second sound emitting device 15 radiate sound waves outward through the respective sound outlet holes. One of the sound emitting devices (e.g., the first sound emitting device 14) serves as a primary sound source for emitting sound; the other sound generating device is used as an auxiliary sound source and is used for reducing or even eliminating sound leakage around the wearer so as to ensure the privacy of the wearer.

The first and second sound emitting devices 14 and 15 may be, but are not limited to, moving coil speakers, moving iron speakers, MEMS speakers, and the like. The following description will be given taking a moving-coil speaker as an example. The moving-coil loudspeaker comprises a vibrating part and a magnetic circuit system matched with the vibrating part. The manner of matching the vibrating portion and the magnetic circuit system is common knowledge in the art and will not be described in detail here.

In operation, the first and second sound generators 14, 15 are in phase opposition to form an acoustic dipole. The opposite phase means that the sound waves radiated outwardly by the two sound emitting devices 14, 15 are 180 ° out of phase. An acoustic dipole refers to a sound source synthesized by two sound sources that are very close together, have the same or similar frequency and vibration amplitude, and are opposite in phase.

The first sound-emitting device 14 and the second sound-emitting device 15 are located at different distances from the same ear opening 17 of the wearer.

Because the phases of the two sound generating devices are opposite, the distance between the two sound generating devices is far smaller than the distance between the sound generating devices and surrounding people, and the two sound generating devices form a sound dipole relative to the surrounding people, sound waves of the two sound generating devices can be at least partially offset when being transmitted to the ears of the surrounding people, so that the sound leakage phenomenon of the sound generating unit is remarkably reduced.

In addition, because the two sound generating devices are at different distances from the same ear hole of the wearer, for example, the distance difference between the two sound generating devices is greater than or equal to 1cm, the two sound generating devices do not form an acoustic dipole relative to the wearer, and therefore the attenuation of the sound wave near the ear hole is small, so that the wearer can hear the sound generated by the sound generating unit. The arrangement mode of the sound production unit improves the listening privacy of a wearer.

In one example, as shown in fig. 2, the first and second sound emitting devices 14 and 15 are responsive to the same electrical signal. The polarities of the first sound generating device 14 and the second sound generating device 15 are opposite, and specifically, the current directions of the two sound generating devices are opposite.

Thus, at the time of vibration, the vibration directions of the vibration portions of the two sound emission devices 14, 15 are opposite to each other, and at the same time, one vibration portion 14a vibrates toward the sound outlet hole direction and the other vibration portion 15a vibrates toward the inside of the sound emission device, so that the phases of the first sound emission device 14 and the second sound emission device 15 are opposite to each other.

In one example, as shown in fig. 3, the first and second sound generators 14, 15 are of the same polarity when installed. The electrical signals of the first and second sound emitting devices 14 and 15 are of opposite polarity. Therefore, when vibrating, the vibrating portions of the two sound emission devices 14 and 15 vibrate in opposite directions, so that the phases of the first sound emission device 14 and the second sound emission device 15 are opposite.

Note that, in this example, the frequency ranges of the sound waves radiated from the two sound emission devices 14 and 15 are the same or close to each other, so that the two sound emission devices 14 and 15 easily form an acoustic dipole. Preferably, the first sound emitting device 14 and the second sound emitting device 15 are of the same model. The two sound generating devices 14 and 15 have the same sound generating frequency, so that the auxiliary sound source has a significant effect of reducing the main sound source around the wearer, and the leakage reduction effect is good.

The distance of the sound outlet openings of the two sound emitting devices 14, 15 should be as small as possible for the person around the wearer to form an acoustic dipole, so that the distance of the sound waves of the two sound emitting devices 14, 15 to the person around the wearer is approximately the same. Due to the superposition of the sound waves, people around the sounding unit cannot hear the sound waves emitted by the sounding unit clearly, and the leakage reduction function of the sounding unit is good.

The distance between the sound outlets of the two sound generators 14, 15 is much smaller than the distance of the sound generators to the surrounding persons. For example, the distance between the first sound emission device 14 and the second sound emission device 15 is less than or equal to 30 mm. In this example, the distance between the two sound emitting devices 14 and 15 is much smaller than the distance between the sound emitting devices and the surrounding persons, and in this range, the leakage reducing effect of the sound emitting unit to the surrounding persons is excellent.

For example, the sound outlet hole of the first sound-emitting device 14 faces the ear hole 17 of the wearer, and the distance from the sound outlet hole of the second sound-emitting device 15 to the ear hole 17 is larger than the distance from the sound outlet hole of the first sound-emitting device 14 to the ear hole 17.

For the wearer, due to the need for listening, the sound outlet of one of the sound emitting devices (e.g., the first sound outlet 16 of the first sound emitting device 14) may be located close to the ear hole 17; while the sound outlet of the other sound-emitting device (e.g., the second sound outlet 19 of the second sound-emitting device 15) is distant from the ear hole 17, thereby forming a distance difference. In this way, the sound waves do not form a large attenuation at the ear hole 17 of the wearer, and the wearer can hear the sound of the sound emitting unit, particularly the sound from the first sound emitting device 14.

Alternatively, the difference between the distance from the sound outlet hole (e.g., the first sound outlet hole 16) of the second sound emitting device 15 to the ear hole 17 and the distance from the sound outlet hole (e.g., the second sound outlet hole 19) of the first sound emitting device 14 to the ear hole 17 is greater than or equal to 5 mm. In this range, the effect of reducing the sensitivity of the second sound generating device 15 to the first sound generating device 14 is small at the ear hole 17, and the wearer can clearly listen to the sound wave radiated from the sound generating unit.

In one example, as shown in fig. 4, the sound outlet hole (e.g., the first sound outlet hole 16) of the first sound emitting device 14, the sound outlet hole (e.g., the second sound outlet hole 19) of the second sound emitting device 15, and the ear hole 17 are located on the same straight line. Thus, when the distance between the other sound outlet holes 16,19 is a predetermined value, the difference between the distances of the two sound outlet holes 16,19 from the ear hole 17 is the largest, and the listening effect of the wearer is good.

In one example, as shown in fig. 1, a cavity is provided within the leg. The sound generating unit is disposed within the cavity. The leg portion is provided with a first sound outlet 16 communicating with the vibrating portion of the first sound emitting device 14 and a second sound outlet 19 communicating with the vibrating portion of the second sound emitting device 15. For example, the leg includes a housing. The cavity is formed inside the shell. The housing is provided with a first sound outlet 16 and a second sound outlet 19. In this example, the sound emitting unit is mounted in a sealed manner. Compared with an open installation mode, the sound production unit can be effectively protected by the legs, and the intelligent glasses are good in appearance.

In one example, the housing includes a body portion and a sound emitting portion that are independently provided. For example, the body portion and the sound emitting portion as a whole constitute a rectangular body. The cross section of the rectangular body is rectangular or approximately rectangular. The sound emitting part is used for accommodating the sound emitting unit. The sound emitting part and the sound emitting unit together form a sound emitting module. After the sound production module is assembled and tested to be qualified, the sound production part is connected with the body part. In this way, the sound emitting unit is of modular design. This makes the replaceability of each part of the leg portion better, reducing the defective rate.

In one example, as shown in fig. 1, the sound outlet holes (e.g., the first sound outlet hole 16) of the first sound emitting device 14 and the sound outlet holes (e.g., the second sound outlet hole 19) of the second sound emitting device 15 are oriented differently. Thus, the second sound emitting device 15 has a small attenuating effect on the first sound emitting device 14 at the ear hole 17, and does not affect the listening effect of the wearer.

In one example, as shown in fig. 1, the sound emitting direction of the first sound emitting device 14 is directed toward the ear hole 17 of the wearer. The second sound emitting device 15 emits sound in a direction away from the wearer. For example, the first sound emitting device 14 radiates sound outward through the first sound outlet hole 16 of the housing. The second sound emission means 15 radiates sound outward through the second sound outlet hole 19 of the housing. The first sound outlet opening 16 is directed towards the ear opening 17. Due to the directivity of the sound waves, particularly the directivity of the medium and high frequency sound waves, the sound emitted by the first sound emitting device 14 can be more clearly heard by the ear of the wearer. The second sound outlet hole 19 is directed perpendicularly to the face of the wearer and outwardly, so that the sound waves radiated from the second sound emitting device 15 have a small attenuating effect on the sound waves radiated from the first sound emitting device 14 at the ear hole 17.

In one example, as shown in fig. 1, the leg portion includes a connection portion 13a and a bent portion 13b connected to one end of the connection portion 13 a. The other end of the connecting portion 13a is hinged to the lens 11. A cavity is provided in the connecting portion 13 a. The connecting portion 13a has a slope 18 facing the ear hole 17 at one end connected to the bent portion 13 b. The first sound outlet hole 16 is opened on the inclined surface 18. The second sound outlet hole 19 is located at a side surface or a top surface of the connection portion 13 a.

For example, the connecting portion 13a includes the housing enclosing the cavity described above. The whole body of the shell is a rectangular body. The first sound-emitting device 14 and the second sound-emitting device 15 are arranged within the cavity, e.g. the two sound-emitting devices 14, 15 are isolated from each other. The bent portion 13b protrudes from an upper portion of one end surface of the connecting portion 13 a. The lower part of the end surface forms a bevel 18.

The housing further comprises two sound outlet openings 16,19 communicating the cavity with the external space. The first sound emitting device 14 radiates sound waves outward through the first sound outlet hole 16. The first sound outlet hole 16 is opened on the inclined surface 18 so as to radiate sound waves toward the ear hole 17. The second sound emission means 15 radiates sound waves outward through the second sound emission hole 19. The second sound outlet holes 19 are opened on the outer side surface of the rectangular body so as to radiate sound waves outward perpendicularly to the wearer's face.

In this example, since the two sound holes 16 and 19 are oriented differently, the sound waves radiated from the second sound emitting device 15 at the ear hole 17 have a small effect of attenuating the sound waves of the first sound emitting device, and the smart glasses have a good sound emitting effect.

In addition, since the second sound outlet holes 19 radiate sound waves outward, the sound around the wearer can be effectively attenuated, and the leakage reduction effect is good.

In one example, the first sound outlet hole 16 extends from a slope to the lower surface of the leg portion. The first sound outlet hole 16 has a flat bar-shaped structure. For example, the first sound outlet hole has a width of 1mm and a length of 8-10 mm. In this example, the first sound outlet 16 is able to radiate sound waves to a wider space near the ear opening, and the wearer's listening is better.

The first sound-emitting device 14 is of the side-emitting type. Due to the adjusting function of the front sound cavity of the first sound-emitting device, the middle-frequency and high-frequency sound-emitting effects of the intelligent glasses are good. The second sound outlet hole 19 faces the vibrating portion 15a of the second sound emitting device 15. The second sound emitting device 15 is of a positive sound emitting type. The second sound generating device 15 has high radiation efficiency and good leakage reduction effect. For example, the second sound outlet 19 has a circular or square shape.

In other examples, both sound emitting devices 14, 15 project outwardly from the leg and are in opposite phase when vibrating. In this example, the two sound emitting devices 14 and 15 are arranged in an open manner. The effect of reducing the sound leakage of the wearer's surroundings can also be achieved.

In other examples, a portion of the cavity forms a rear acoustic cavity of the first acoustic device 14. And the sound absorption material is filled in the rear sound cavity. This makes the low frequency of the smart glasses work well.

It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention.
