Fig. 1 shows a schematic view of a smart headset 1 according to an embodiment of the present application. The smart headset 1 includes a body 10 and first and second side portions 100 and 200 connected to the body 10, the first and second side portions 100 and 200 extending from both ends of the body 10 toward the same side of the body 10 and including first and second sound emitting devices 110 and 210, respectively. Specifically, the smart headset 1 may be, for example, AR glasses as shown in fig. 1, and at least one lens 11 may be disposed on the body 10 for displaying or viewing, where the at least one lens 11 may be fixedly connected to the body 10 or detachably connected to the body 10, and in some embodiments, the at least one lens 11 may be a photochromic lens or an electrochromic lens, or other common optical lenses.

In other embodiments, the smart headset 1 may also be VR glasses, MR glasses, or other smart glasses or smart head-mounted devices provided with the first side 100 and the second side 200. . The smart headset 1 further includes a signal processor 300 (see fig. 2) electrically connected to the first sound emitting device 110 and the second sound emitting device 210, wherein the signal processor 300 sends electrical signals with opposite phases to the first sound emitting device 110 and the second sound emitting device 210, so that the vibration directions of the vibrators in the first sound emitting device 110 and the second sound emitting device 210 are opposite, and therefore the first sound emitting device 110 and the second sound emitting device 210 generate sound waves with opposite phases (preferably, the same amplitude), and the sound waves with opposite phases form a pair of sound dipoles, so that sound wave cancellation is formed in the environment around the wearer, thereby reducing the amount of sound leakage, reducing noise interference to surrounding people, and improving privacy protection for the wearer.

Under this kind of arrangement, this paper states intelligent head-mounted device through arranging sound generating mechanism on two lateral parts respectively to two sound generating mechanism send opposite in phase's signal of telecommunication, make sound generating mechanism form the sound dipole at the sound wave of wearer both sides, thereby reduced the sound wave vibration around the wearer, especially the noise in wearer the place ahead and rear obtains obviously reducing, thereby reduced the noise leakage volume in the environment, improved wearer's privacy security, reduced the interference to personnel on every side.

Further implementation or refinement, improvement procedures with respect to the smart headset will be described below by way of exemplary illustration in order to further improve its operational efficiency, reliability or improvement considerations in other respects.

In the embodiment shown in fig. 1, the first sound generating device 110 and the second sound generating device 210 may be disposed at the same distance from the body 10, for example, symmetrically arranged about the center plane of the body 10, so that the first sound generating device 110 and the second sound generating device 210 have the same distance to the spatial position right in front of or right behind the wearer, and the sound waves emitted therefrom are cancelled out in the surroundings of the wearer, particularly the spatial position right in front of or right behind the wearer, to reduce the leakage of sound to the outside.

Specifically, fig. 2 shows a schematic diagram of electrical connection between the signal processor 300 and the sound emitting device, wherein a positive electrode and a negative electrode of the signal processor 300 may be electrically connected with a positive electrode and a negative electrode of the first sound emitting device 110, respectively, and a positive electrode and a negative electrode of the signal processor 300 may be electrically connected with a negative electrode and a positive electrode of the second sound emitting device 210, respectively, so as to enable the signal processor 300 to transmit electrical signals with opposite phases to the first sound emitting device 110 and the second sound emitting device 210.

Fig. 3 is a graph comparing the muffling effect according to an embodiment of the present application with that of the prior art, showing the frequency response curve (frequency-sensitivity curve) at a position 30 cm in front of the wearer, and it can be seen by comparison that the embodiment of the present application reduces the far-field leakage by about 10 dB compared to the prior art, and the improvement is more obvious for the far-field leakage around the wearer.

In one embodiment, the first sound emitting device 110 includes a first sound emitter 111, the second sound emitting device 210 includes a second sound emitter 211, the first side portion 100 includes a first cavity, the second side portion 200 includes a second cavity, and the first and second sound emitters 111 and 211 are disposed in the first and second cavities, respectively. The first sound generator 111 includes a first vibrator, the first vibrator divides the first cavity into a first front sound cavity and a first rear sound cavity, the first front sound cavity has a first front sound cavity sound outlet 1111, the first rear sound cavity has a first rear sound cavity sound outlet 1112, the first vibrator compresses air in the first front sound cavity and expands air in the rear sound cavity, and vice versa, so that sound waves emitted from the first front sound cavity sound outlet 1111 and sound waves emitted from the first rear sound cavity sound outlet 1112 keep the same amplitude and opposite phase at all times, and form a pair of sound dipoles, thereby canceling sound leaking from the side of the wearer. Likewise, the second sounder 211 includes a second vibrator that divides the second cavity into a second front sound chamber having second front sound chamber sound outlet holes 2111 and a second rear sound chamber having second rear sound chamber sound outlet holes 2112, and the second front sound chamber sound outlet holes 2111 and the second rear sound chamber sound outlet holes 2112 emit sound waves in opposite phases based on the vibration of the second vibrator. Therefore, for the surrounding environment of the wearer, primary sound wave cancellation is also realized by the front sound cavity sound outlet hole and the rear sound cavity sound outlet hole of the same side part, and meanwhile, due to the fact that the phases of the sound generating devices on the two sides are opposite, the synthetic sound wave of the first side part after being cancelled by the first front sound cavity sound outlet hole 1111 and the first rear sound cavity sound outlet hole 1112 and the synthetic sound wave of the second side part after being cancelled by the second front sound cavity sound outlet hole 2111 and the second rear sound cavity sound outlet hole 2112 are opposite in phase, so that secondary sound wave cancellation is realized by the synthetic sound wave of the first side part and the synthetic sound wave of the second side part, and the sound leakage amount can be greatly reduced under the dual sound wave cancellation.

In the embodiment shown in fig. 1, a first front sound cavity sound outlet hole 1111 is provided in the lower bottom surface (i.e., the surface facing the ground when worn) of the first side portion 100 and aligned with the pinna of the corresponding side of the wearer, and a first rear sound cavity sound outlet hole 1112 is provided in the side of the first side portion 100 facing away from the wearer; a second front sound cavity exit hole 2111 is provided in the lower bottom surface of the second side portion 200 and aligned with the pinna of the corresponding side of the wearer, and a second rear sound cavity exit hole 2112 is provided on the side of the second side portion 200 facing away from the wearer.

Further, the front and rear sound cavity sound outlet holes of each side may be at different distances from the ear hole of the wearer, for example, the distance from the first front sound cavity sound outlet hole 1111 to the ear hole of the corresponding side of the wearer and the distance from the first rear sound cavity sound outlet hole 1112 to the ear hole of the corresponding side of the wearer may be different by more than 5 mm; the distance from the second front sound cavity exit hole 2111 to the ear hole on the wearer's corresponding side and the distance from the second rear sound cavity exit hole 2112 to the ear hole on the wearer's corresponding side may differ by 5 mm or more. Under this kind of arrangement, when the produced sound wave of front sound chamber sound outlet and back sound chamber sound outlet transmitted the earhole, amplitude difference was great, and cancellation of both at earhole department is less, and what the wearer's earhole mainly received is the produced sound wave of front sound chamber to, can not produce too big influence to wearer's acoustics experience. For example, fig. 4 shows a comparison graph (frequency-sensitivity curve) of the frequency response curve of the sound pressure in the ear of the wearer according to an embodiment of the present application with that of the prior art, and it can be seen from the comparison that the present embodiment only causes a small reduction in the sound pressure in the ear of the wearer, and has a small influence on the acoustic experience of the wearer.

In other embodiments, the rear sound cavity sound outlet hole may be located at other positions, such as a lower bottom surface of the corresponding side portion and an upper top surface of the corresponding side portion (i.e., a surface facing away from the ground when worn), as long as the distance from the front sound cavity sound outlet hole to the ear hole is different. Furthermore, it is understood that 5 mm is not the only threshold, and the smaller the distance difference between the front and rear sound cavity sound outlet holes to the ear hole, the smaller the leakage of sound to the surroundings, but the lower the sound pressure of the wearer's ear; the larger the distance, the larger the amount of sound leakage to the surroundings, but the smaller the amount of reduction in the in-ear sound pressure to the wearer. The specific distance difference is determined according to the acoustic specification of the sound generating device, the distance between the two sound emitting holes can be properly reduced for the sound generating device with higher sensitivity, and the distance between the two sound emitting holes can be properly increased for the sound generating device with lower sensitivity. The distance difference mentioned here is for realizing sound field cancellation and ensuring acoustic effect, and therefore is not limited to that the distance from the rear sound cavity sound outlet (e.g. first rear sound cavity sound outlet 1112 and second rear sound cavity sound outlet 2112) to the ear hole of the wearer is greater than the distance from the front sound cavity sound outlet (e.g. first front sound cavity sound outlet 1111 and second front sound cavity sound outlet 2111) to the ear hole of the wearer as shown in fig. 1, and may be set such that the distance from the front sound cavity sound outlet (e.g. first front sound cavity sound outlet 1111 and second front sound cavity sound outlet 2111) to the ear hole of the wearer is greater than the distance from the rear sound cavity sound outlet (e.g. first rear sound cavity sound outlet 1112 and second rear sound cavity sound outlet 2112) to the ear hole of the wearer.

In other embodiments, the first sound emitting device 110 may also include a plurality of first sound emitters 111, and the positive electrode and the negative electrode of each first sound emitter 111 in the plurality of first sound emitters 111 are electrically connected to the positive electrode and the negative electrode of the signal processor 300, respectively; the second sound generator 210 may also comprise a plurality of second sound generators 211, each of the plurality of second sound generators 211 having a positive and a negative pole electrically connected to the negative and positive pole of the signal processor 300, respectively. The plurality of first sounders 111 and the plurality of second sounders 211 may be arranged in the same array (e.g., four first sounders 111 arranged in a rectangular array on the first side 100 and four second sounders 211 arranged in the same rectangular array on the second side 200) such that the first and second sound emitting devices 110, 210 still form an acoustic dipole overall for sound wave cancellation, while at each side the arrangement of the plurality of sounders may enhance the sound effect, thereby optimizing the hearing experience of the wearer.

Under this kind of arrangement, effectively reduced the sound leakage around the wearer of intelligent head-mounted device according to this application, improved wearer's privacy protection to reduce the noise interference to personnel around, and further improved privacy and the travelling comfort of the intelligent system including this intelligent head-mounted device.

The above examples mainly illustrate the smart headset of the present application and the smart system including the smart headset. Although only a few embodiments of the present application have been described, those skilled in the art will appreciate that the present application may be embodied in many other forms without departing from the spirit or scope thereof.
