The smart headset according to the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The disclosed embodiment provides an intelligent headset, and referring to fig. 1, fig. 2, and fig. 5 to fig. 7, the intelligent headset includes a frame 11 and a temple 12, the temple 12 has a first end 121 and a second end 122 that are disposed opposite to each other, and the first end 121 of the temple 12 is connected to the frame 11; the intelligent head-mounted equipment further comprises an installation part 13 and a directional loudspeaker 14, wherein the directional loudspeaker 14 is arranged on the installation part 13; the mounting part 13 is arranged on the glasses leg 12, and the mounting part 13 is positioned on the bottom surface of the glasses leg 12 when the intelligent head-mounted equipment is in a wearing state; the mounting part 13 is fixedly connected with the temple 12, and the directional loudspeaker 14 is arranged towards the second end 122 of the temple 12; alternatively, the mounting portion 13 may be rotatably coupled to the temple 12, and when the mounting portion 13 is rotated to a first predetermined position, the directional speaker 14 faces the second end 122 of the temple 12.

Referring to fig. 1 and 3, in the smart headset provided by the embodiment of the present disclosure, by providing a mounting portion 13 on the bottom surface of a temple 12 of the smart headset, and providing a directional speaker 14 on the mounting portion 13, the directional speaker 14 faces a second end 122 of the temple 12, when the smart headset is in a wearing state, the directional speaker 14 may be located in a direction facing towards the human ear on the front side of the human ear. The directional loudspeaker 14 can realize the directional transmission of sound signals, the directional loudspeaker 14 can emit ultrasonic waves, and the frequency coverage range of the ultrasonic waves is 20 kHz-100 kHz. In the process of ultrasonic wave propagation, due to the nonlinear demodulation effect of the air medium, the required audio signal can be finally obtained in a specific area. Therefore, by utilizing the directivity characteristic of the ultrasonic wave and the nonlinear demodulation effect of the air, the audio signal in the sound wave can be self-demodulated in the process of propagation, the required audio signal which can be directly heard by the human ear is finally obtained, and the audio signal with the frequency range of 20Hz-20kHz can be heard by the human ear. The specific principle is as follows: for example, the directional speaker 14 emits two ultrasonic waves with frequencies of f1 and f2, and the two ultrasonic waves are subjected to nonlinear demodulation action of air, so that sound waves of f1, f2, f1+ f2, f1-f2, 2f1, 2f2 and the like are finally obtained. By reasonably selecting f1 and f2, the difference frequency sound waves f1-f2 in the audible sound frequency domain can be obtained. For example, f 1-41 kHz and f 2-40 kHz, an audible sound with a difference frequency of 1kHz is obtained. With audio directional technology, sound can travel along a straight line like light, with high directivity. Referring to fig. 3, since the directional speaker 14 is aligned with the ear of the user when the smart headset is worn, only the user himself can hear the sound emitted by the directional speaker 14, and the other people cannot hear the sound, so that not only the privacy of the user is ensured, but also the influence on the other people is avoided. Referring to fig. 4, the audio signal f0 is processed by digital signal processing and modulated to obtain an ultrasonic signal f1 and an ultrasonic signal f2, and after passing through a power amplifier and a directional speaker, the ultrasonic signals f1, f2, f1+ f2, 2f1, 2f2, etc. and a sound signal f0(f1-f2) audible to human ears are finally obtained due to the nonlinear demodulation effect of air.

Referring to fig. 2, in one embodiment, with the mounting portion 13 fixedly connected to the temple 12, the mounting portion 13 extends downward along the bottom surface of the temple 12 to form a mounting surface 130 facing the second end 122 of the temple 12 when the smart headset is in a wearing state, and the directional speaker 14 is disposed on the mounting surface 130.

In this embodiment, since the mounting portion 13 is fixedly connected to the temple 12, the orientation of the directional speaker 14 is fixed, and when the smart headset is worn, the directional speaker 14 is directed to the ear of the user, and the sound emitted by the directional speaker 14 can be heard by the user.

Further, the mounting portion 13 and the temple 12 are integrally formed.

In this embodiment, the installation part 13 and the temple 12 are integrally formed, the installation part 13 is more stable and firm, and the manufacturing process is more convenient, and when the temple 12 is manufactured, the bottom surface of the temple 12 directly protrudes downwards to extend for a section to be used as the installation part 13. Of course, the mounting portion 13 and the temple 12 may be provided in a separate body, and then the mounting portion 13 may be welded or bonded to the bottom surface of the temple 12.

Referring to fig. 5 and 6, in one embodiment, in a case where the mounting part 13 is rotatably coupled to the temple 12, the mounting part 13 includes a mounting plate 131 and a first rotation shaft 132; when the smart headset is in a wearing state, the first rotating shaft 132 is disposed on the bottom surface of the temple 12, the mounting plate 131 is rotatably connected to the first rotating shaft 132, the mounting plate 131 has a first side 1310, the directional speaker 14 is disposed on the first side 1310, the mounting plate 131 can rotate in a first direction to switch between a first preset position where the directional speaker 14 faces the second end 122 of the temple 12 and a second preset position where the first side 1310 is in contact with the bottom surface of the temple 12, and the directional speaker 14 is in a shielding state.

In this embodiment, the mounting portion 13 is not stationary but is rotatable. Referring to fig. 5, 6 and 7, the mounting plate 131 has a first preset position and a second preset position, and the mounting plate 131 can rotate around the first rotating shaft 132 along a first direction to switch between the first preset position and the second preset position. When the directional speaker 14 is not used, the mounting plate 131 is located at a position approximately parallel to the bottom surface of the temple 12, the first side 1310 is in contact with the bottom surface of the temple 12, and the directional speaker 14 is shielded by the temple 12, so that the directional speaker 14 can be protected, and the intelligent headset can be conveniently stored; when it is desired to listen to sound using directional speaker 14, mounting plate 131 is rotated clockwise by an angle α about first rotational axis 132 in a first direction, and first side 1310 with directional speaker 14 is directed toward second end 122 of temple 12, when the smart headset is worn, directional speaker 14 is located in front of the ear of a person and directed toward the ear of the person, and directional speaker 14 is directed toward the ear of the person, so that only the user himself can hear the sound emitted by directional speaker 14, and others cannot hear the sound. After the use, the directional speaker 14 can be retracted after the mounting plate 131 rotates counterclockwise around the first rotating shaft 132 by an angle α along the first direction, which is convenient for the storage of the smart headset and is also beneficial to protecting the directional speaker 14. Alternatively, the angle α may be, for example, 90 °.
