Bearing information.

Furthermore, the control unit 12 is connected to a mobile unit 13, which is configured to transmit a movement command to the mobile unit 13 based on the orientation information. The mobile unit 13 is coupled to the audio device 14, and the mobile unit 13 is configured to control the position of the speaker of the audio device 14 toward the position of the human ear in accordance with the movement command.

Optionally, the control unit 12 is further configured to calculate the movement information based on the orientation information and to control the movement direction and/or the movement speed of the mobile unit 13 by transmitting the movement information to the mobile unit 13. It should be understood that the control unit 12 may separately control the moving direction of the moving unit 13, or may separately control the moving speed of the moving unit 13, or may simultaneously control the moving direction and moving speed of the moving unit 13.

As shown in FIG. 2, the audio device 14 is a directional speaker device, and the number of the audio devices 14 is at least two, which may include a first directional speaker device 141 and a second directional speaker device 142, and the first directional speaker device 141. The second directional speaker device 142 is connected to the mobile unit 13, respectively. These directional speaker devices can also be long cylindrical audio devices.

Further, as shown in FIG. 2, the moving unit 13 is a rotating mechanism, and the number of the moving units 13 is at least two, and the first rotating mechanism 131 and the second rotating mechanism 132 may be included. Two acoustic devices 14 are respectively disposed on the two mobile units 13. It should be understood that both the first rotating mechanism 131 and the second rotating mechanism 132 are coupled to the control unit 12. The first rotating mechanism 131 is connected to the first directional speaker device 141, configured to drive the first directional speaker device 141 to rotate under the control of the control unit 12, and the second rotating mechanism 132 is connected to the second directional speaker device 142, configured as The second directional speaker device 142 is rotated under the control of the control unit 12.

It should be noted that the sound of the traditional sound is spread in all directions. For example, the ordinary sound is spread by 360°, 720° and the like. The directional speaker can direct the sound, and the directional sound can be transmitted without being significantly attenuated by the distance, so the sound can be transmitted far away, up to 30 meters to 50 meters. Therefore, the directional speaker is quite different from the ordinary speaker, and the sound of the directional speaker is transmitted only in one direction.

Therefore, in practical applications, the acoustic mechanism 1 may include a camera 111, an MCU 121, a rotating mechanism, a long-tube sound, and the like. The camera 111 is configured to capture the direction of the human eye, obtain the orientation information of the ear through the eye direction, and transmit the orientation information of the ear to the MCU 121, and the MCU 121 receives the ear orientation information for arithmetic processing, and transmits an instruction to the rotation mechanism, so that each rotation mechanism The direction of rotation can be adjusted according to the direction of the ear. Since the long-tube sound is mounted on the rotating mechanism, the orientation of the speaker of the long-tube sound can be changed with the rotation of the rotating mechanism.

As another embodiment of the embodiment, the image capturing unit 11 such as the image capturing apparatus acquires the position of the human head and transmits it to the MCU 121, and the MCU 121 obtains the left ear position of the person through the left eye position of the person, and obtains the person by the right eye position of the person. In the right ear position, the MCU 121 controls the rotation direction and/or the rotation speed of the left rotation mechanism and the right rotation mechanism, the left rotation mechanism drives the left directional speaker device to propagate the sound to the left ear direction of the person, and the right rotation mechanism drives the right directional speaker. The device transmits sound to the person's right ear orientation.

In practical applications, when music or film is shown, the rotating mechanism in several speakers drives the middle and high-pitched speaker system to rotate, and the speaker is facing the user's head, from left to right, or from top to bottom, etc. Various different ways of sweeping enable users to experience the changes in the orientation of people and objects in the movie to achieve true 3D stereo sound. Of course, the sound size can be adjusted with the movie plot.

As another embodiment of the embodiment, two or more speakers may be placed at positions such as the left front and the right front of the user. A highly directional mid-high tweeter system is built into each speaker. This horn system is driven by a rotating mechanism, which can achieve the purpose of turning up, down, left and right. The audio and control systems of several speakers can be connected via Bluetooth, WIFI, wired, etc. The speaker is wired or wirelessly connected to a camera 111 so that the user's head position can be tracked at any time. Therefore, the direction of sound propagation can vary with the direction of the ear, or it can change as the size of the music changes.

Therefore, the adaptive ear following system can make the acoustic direction follow the orientation of the human ear, thereby realizing the change of the sound of different sizes and sizes, and achieving the experience of the stereo sound, and the sound size can also actively change following the movie plot. The long-tube directional speaker can transmit sound in a fixed direction without propagating sound in other directions. Therefore, the listening sound in the direction in which the long tube is facing is large, and the sound in other directions is small. In practical applications, the acoustic mechanism 1 can be mounted on the wall or suspended on the ground.

For the prior art, in order to achieve a good sound effect, people will adjust the sound of the sound very large, but in fact, the sound received by my ear is really a small part, most of the sound is scattered around, this is the surrounding People cause sound interference and influence. And if the device with headphones is inconvenient to use, and the headphones, the headset, etc. also make the sound limited, limiting the stereo sound effect.

By providing the acoustic mechanism 1, the camera 111 can realize the tracking of the human brain by capturing the position of the human eye, and the sound size and height in different directions are also different, so as to achieve a better stereo effect. Using the left and right long-tube directional speakers, the sound is transmitted to the human ear, and the ears can be heard by vibrating, azimuth changes, etc. by sweeping up and down and left and right. This effect is not achievable with traditional sound. Therefore, the audio mechanism 1 can also be an audio system capable of realizing special sound effects to prevent interference with others, and can not only affect the free movement of the user, but also allow the user to hear a variety of three-dimensional sounds that are very exciting. Can not interfere with other people.
